Our Process
Reclaimed lumber does not process itself. Turning a rough salvaged beam into a precision-milled, job-site-ready board takes eight distinct stages — each one critical to the quality of the final product.
Eight Steps from Salvage to Delivery
Every piece of lumber we sell has passed through a rigorous, multi-stage process designed to ensure structural soundness, dimensional accuracy, and the preservation of the character that makes reclaimed wood special. Here is exactly how it works.
Sourcing & Salvage
Every piece of reclaimed lumber starts somewhere — a barn being taken down in rural Minnesota, a warehouse renovation in Northeast Minneapolis, a bridge replacement in Wisconsin, or a homeowner with a stack of dimensional lumber left over from a remodel. We maintain relationships with demolition contractors, property owners, and salvage crews across the upper Midwest, and we actively seek out structures slated for demolition that contain high-quality timber.
Quality Checkpoint
Before any material is loaded for transport to our yard, it passes a preliminary field inspection. Boards with visible rot, active insect infestation, or severe structural damage are separated on-site. Only material with reasonable salvage potential makes the trip to Roseville.
Key Details
- On-site evaluation of available lumber before purchase
- Hand deconstruction for high-value structures to maximize recovery
- Partnerships with 30+ demolition and renovation contractors
- Sourcing radius of 150 miles from Minneapolis for minimal transport impact
- Provenance documentation for every lot — we record what building the wood came from
Pre-Purchase Evaluation
Before we commit to buying material or deconstructing a structure, our team visits the site to assess the lumber. We identify species, estimate board footage, evaluate condition, and check for hazardous materials like lead paint or asbestos (common in pre-1978 structures). This evaluation determines whether the salvage is economically viable and what grade of material we can expect to recover.
Deconstruction Planning
For full building deconstructions, we develop a disassembly plan that maximizes material recovery. We identify load-bearing members that need to come out last, plan the removal sequence for sheathing and framing, and stage equipment and dumpsters for non-wood debris. The goal is to extract every usable board intact, with minimal splitting, cracking, or damage.
Inspection & Sorting
When lumber arrives at our Roseville yard, it enters the inspection queue. Our team evaluates every board for species identification, structural integrity, moisture content, and defect analysis. We are looking for rot, insect damage, excessive checking, and any compromise that would make a board unsuitable for reuse. Wood that passes inspection moves to the processing line. Wood that does not is diverted — but never wasted. Below-grade material is repurposed for non-structural applications, composted, or donated.
Quality Checkpoint
Every board that enters our processing line has been individually inspected and species-identified. Boards that do not pass inspection are marked and diverted to our secondary-use bins (short pieces, craft wood, compost stock) or donated to Habitat for Humanity ReStore.
Key Details
- Species identification: oak, pine, fir, maple, walnut, elm, and more
- Moisture meter readings on every board to ensure stability
- Visual and tap-test inspection for hidden rot or insect galleries
- Sorting by species, dimension, grade, and intended use
- Rejection rate of approximately 15% — we are selective so our customers do not have to be
Species Identification Protocol
Accurate species identification is critical for grading and pricing. Our team uses a combination of visual grain analysis, end-grain examination under magnification, weight-per-volume comparison, and — when necessary — chemical spot tests. The most common species we process are white oak, red oak, heart pine (longleaf), Douglas fir, white pine, maple, elm, walnut, and poplar. Each species has different structural properties, workability characteristics, and market value.
Moisture Assessment
We use both pin-type and pinless moisture meters to assess the moisture content of incoming material. For most reclaimed lumber that has been in a structure for decades, moisture content is typically between 8% and 14% — well within the acceptable range for interior use. Material that reads above 14% is separated and air-dried in our covered staging area until it reaches equilibrium. We never rush this process — dimensionally unstable lumber causes problems downstream.
De-Nailing & Cleaning
Reclaimed lumber arrives full of metal — nails, screws, staples, lag bolts, and sometimes decades-old hardware embedded deep in the grain. Removing these fasteners without damaging the wood is one of the most labor-intensive steps in our process, and it is the step that separates professional reclaimed lumber from the rough salvage you might find at a salvage yard. Our crew uses electromagnetic detection to find buried metal, then hand-extracts each fastener with care to avoid splitting the surrounding wood.
Quality Checkpoint
After de-nailing, every board goes through a second electromagnetic scan to verify that all metal has been removed. Boards that still show metal readings are returned to the de-nailing station. No board advances to milling until it passes the second scan clean.
Key Details
- Electromagnetic metal scanning on every board — both faces and edges
- Hand extraction of all fasteners to preserve surrounding wood fibers
- Surface cleaning to remove dirt, debris, and loose material
- All extracted metal is recycled — nails, bolts, and hardware go to local scrap yards
- Average de-nailing time: 2 to 5 minutes per board depending on fastener density
Electromagnetic Scanning
We use handheld electromagnetic metal detectors calibrated to detect ferrous and non-ferrous metals at depths up to 2 inches below the surface. Every board is scanned on both faces and both edges. Detected metal locations are marked with chalk before extraction begins. This step prevents the catastrophic equipment damage that occurs when buried metal hits a planer blade or bandsaw tooth — a single missed nail can destroy a $400 blade and create a dangerous projectile.
Fastener Extraction Technique
Our de-nailing crew uses specialized tools — cat's paw nail pullers, flush-cut nippers, and slide-hammer extractors — to remove fasteners without splitting the wood around them. For deeply embedded lag bolts, we use careful drilling to extract the bolt without enlarging the hole beyond the original diameter. The goal is to leave the smallest possible footprint from the extraction, preserving the board's usable surface area.
Grading & Classification
After cleaning, every board is graded. We use a classification system adapted from NHLA hardwood grading standards, modified for the realities of reclaimed material. Our grades account for structural soundness, surface condition, nail-hole density, and aesthetic character. The grading is transparent — every piece in our inventory is tagged with its species, grade, dimensions, and source lot. Customers know exactly what they are buying.
Quality Checkpoint
Every graded board is tagged with a physical label showing species, grade, dimensions (length x width x thickness), source lot number, and date graded. This tag stays with the board through storage, milling, and delivery. If a customer has a question about any board, we can trace it back to the structure it came from.
Key Details
- Premium Select: Minimal defects, tight grain, excellent for visible applications
- #1 Common: Sound structure with moderate character marks — ideal for flooring and paneling
- #2 Common: More character, suitable for rustic applications, accent walls, and furniture
- Structural: Graded for load-bearing use — beams, posts, and framing
- Rustic/Barnwood: Maximum character with weathering and patina — decorative use
Structural Integrity Assessment
For material graded as Structural, we go beyond visual inspection. We perform tap-tests to detect internal voids, check for compression wood that may indicate prior stress, and evaluate grain runout (the angle of grain relative to the edge of the board). Beams and posts intended for load-bearing applications are assessed for twist, bow, and crook. We do not certify structural grades to engineering specifications — a licensed structural engineer should evaluate beams for critical applications — but our Structural grade indicates material that is sound, free of rot and insect damage, and suitable for framing and support use.
Aesthetic Grading Criteria
For finish-grade material (Premium Select and #1 Common), we evaluate surface condition in detail: nail-hole density per square foot, depth and severity of checking, presence of staining or discoloration, and the quality of the grain pattern. Premium Select material has fewer than 3 nail holes per square foot, minimal checking, and consistent color. #1 Common allows more character but remains structurally sound with a presentable surface. The line between grades is a judgment call made by experienced graders — we err on the side of conservative grading so customers are never disappointed.
Storage & Seasoning
Properly storing reclaimed lumber is critical to maintaining its quality. Unlike new kiln-dried lumber that arrives at a uniform moisture content, reclaimed wood may come from a variety of environments — dry interior framing, damp barn walls, or weather-exposed siding. Our storage protocols ensure that all material reaches a stable equilibrium moisture content before milling or sale.
Quality Checkpoint
Before any stored material is pulled for milling or customer pickup, it receives a spot moisture check. Material reading above 12% for interior-use applications is held until it reaches target range. This prevents the warping, cupping, and gapping issues that occur when high-moisture wood is installed in conditioned spaces.
Key Details
- Covered storage racks with adequate airflow on all sides of stacked material
- Stickering between layers — 3/4-inch spacers every 24 inches for even air circulation
- Separation by species and intended use to prevent moisture cross-contamination
- Regular moisture monitoring of stored inventory — spot checks on a weekly cycle
- Minimum 30-day acclimation period for material from humid or outdoor environments
Environmental Controls
Our covered storage area maintains ambient temperature with natural ventilation. We avoid heated storage because rapid drying can cause case-hardening and internal stress in wood that has been in a high-moisture environment. Instead, we allow material to reach equilibrium gradually — a process that may take 4 to 8 weeks for heavily saturated stock. For most reclaimed lumber that was in a conditioned building interior, the acclimation period is minimal.
Inventory Rotation
We operate on a first-in, first-out inventory system for species and grade categories. Material that has been in storage longest is offered to customers first. This ensures that buyers receive material that has had maximum acclimation time and that our inventory does not stagnate. We also conduct quarterly inventory audits to identify and re-grade any material that shows changes in condition during storage.
Milling & Fabrication
This is where raw reclaimed timber becomes a finished product. Our milling shop is equipped to handle the unique challenges of reclaimed wood — case-hardened surfaces, irregular dimensions, and the density of old-growth timber that modern planers were not designed for. We run a wide-belt sander, a 20-inch thickness planer, a resaw bandsaw, a tongue-and-groove profiler, and a table saw for ripping to width. Whether you need a rough-sawn beam cleaned up on two faces or 1,000 square feet of tongue-and-groove flooring milled from reclaimed heart pine, we handle it in-house.
Quality Checkpoint
After milling, every board is checked for dimensional accuracy using digital calipers. Target tolerance is within 1/32 inch of specified dimensions. Boards with tear-out, snipe, or profiling defects are pulled and re-milled or downgraded. Profile fit is verified by test-assembling a 3-board section from each milling run.
Key Details
- Thickness planing from rough to S2S, S3S, or S4S
- Resawing thick stock into thinner boards for maximum yield
- Tongue-and-groove profiling for flooring and wall paneling
- Shiplap and V-groove profiles for siding and accent walls
- Custom dimensioning to exact project specifications
- Light sanding for smooth finish or skip-planing to preserve texture
Equipment & Tooling
Standard woodworking equipment struggles with reclaimed lumber. The density of old-growth wood dulls blades faster. Case-hardened surfaces resist standard planer settings. We run carbide-tipped tooling on all milling equipment, maintain an aggressive blade-sharpening schedule (typically every 500-800 board feet of throughput), and use slower feed rates calibrated for the higher density of aged timber. Our resaw bandsaw uses a 1.5-inch, 3 TPI bi-metal blade specifically chosen for its resistance to the stress fractures that plague standard blades when cutting through old-growth material.
Custom Profile Capabilities
Beyond standard S4S surfacing, we offer a range of profile options: tongue-and-groove (3/4-inch, 1-inch, and 5/4-inch thicknesses), shiplap (with 1-inch overlap), V-groove paneling, board-and-batten, and custom profiles for unique architectural applications. Our tongue-and-groove profiler creates a consistent 1/4-inch tongue with a matching groove, and we test-fit profiles from each batch to verify engagement before the full run proceeds.
Quality Control
Before any order leaves the shop, it goes through a final quality check. We verify dimensions with digital calipers, check moisture content one more time, and inspect every board for any defects that may have been revealed during milling. Tongue-and-groove profiles are test-fit to ensure consistent engagement. Beams are checked for twist and bow. Boards that do not meet spec are pulled and replaced. We would rather delay a delivery by a day than ship material that does not meet our standards.
Quality Checkpoint
The final quality checkpoint is a sign-off by the order preparer and a countersign by the yard manager. Both must confirm that the order matches specifications before it is cleared for delivery or pickup.
Key Details
- Dimensional accuracy verified to within 1/32 inch
- Final moisture content check — target range of 6% to 12% for interior use
- Profile fit testing on all tongue-and-groove and shiplap products
- Beam straightness and twist evaluation
- Order count verification — every board is counted, not estimated
Pre-Shipment Inspection
The final inspection is a separate step from the milling quality check. A different team member reviews the completed order against the original specifications — verifying species, grade, dimensions, profile type, board count, and total board footage. This second-set-of-eyes approach catches errors that can slip through when the same person who milled the order also checks it.
Documentation & Tagging
Each order is accompanied by a packing list that itemizes every piece: species, grade, dimensions, and board footage. For customers who have requested Environmental Impact Certificates, we calculate and attach the certificate at this stage — documenting the CO₂ prevented, equivalent trees preserved, and landfill tonnage diverted by the specific order. All documentation is copied to our records for traceability.
Delivery & Logistics
The last mile matters. We operate our own flatbed trucks for delivery across the Twin Cities metro and arrange freight for shipments throughout Minnesota and the upper Midwest. Lumber is banded, stickered for airflow during transit, and loaded to prevent shifting. For large orders, we coordinate delivery timing with your project schedule so material arrives when you need it, not when it is convenient for us. We also offer will-call pickup at our Roseville yard for customers who prefer to transport their own material.
Quality Checkpoint
Upon delivery, we perform a joint count with the receiving party to verify that all material has arrived in the specified quantities and condition. Any transit damage is documented on-site and replacement material is dispatched within 48 hours. For will-call pickups, we provide a loading verification before the customer leaves the yard.
Key Details
- Dedicated flatbed delivery within the Twin Cities metro area
- Freight coordination for greater Minnesota, Wisconsin, Iowa, and the Dakotas
- Lumber banded and stickered for safe transport
- Delivery scheduling coordinated with your project timeline
- Will-call pickup available at 2366 Rose Pl W, Roseville, MN 55113
- Forklift loading for pickup customers
Loading & Transport Protocols
Lumber is loaded onto our flatbed trucks in a specific sequence: heaviest items (beams and timbers) on the bottom, dimensional stock in the middle, and finish-grade material on top, wrapped in protective plastic. All loads are secured with ratchet straps at minimum 4-foot intervals and corner-protected where straps contact finished surfaces. For long-haul deliveries, we use tarps to protect material from road spray and weather.
Staged Delivery for Large Projects
For commercial projects and large residential builds, we offer staged delivery — splitting the order into multiple shipments timed to match your construction schedule. This reduces on-site storage requirements and ensures that material is not exposed to weather or job-site damage longer than necessary. We coordinate staging schedules directly with the project superintendent or general contractor.
Equipment & Technology
Processing reclaimed lumber requires specialized equipment configured for the unique demands of aged, dense, metal-scarred timber. Here is what we run in our shop and why it matters.
20-Inch Thickness Planer
Surface both faces of boards to uniform thickness. Handles stock up to 20 inches wide and 8 inches thick.
Specs: Carbide-tipped cutterhead, variable feed rate from 8 to 24 FPM, helical cutterhead design for reduced tear-out on difficult grain.

Pin & Pinless Moisture Meters
Measuring moisture content at multiple points on every board. Pin meters provide depth readings; pinless meters scan surface zones quickly.
Specs: Accuracy of plus or minus 0.5% MC. Species-specific correction factors applied for accurate readings on different wood types.
Dust Collection System
Capturing sawdust, chips, and airborne particles from all milling equipment. Maintains air quality in the shop and collects material for composting.
Specs: Central collection with 4-inch main duct and branch connections to each machine. Cyclone separator for primary filtration, bag filter for fine particles.
Waste Stream Management
Our goal is 100% material utilization. Every byproduct of our processing has a destination that is not a landfill. Here is how we manage each waste stream.
| Material Stream | Destination | % of Waste |
|---|---|---|
| Usable Off-Cuts (12 inches and longer) | Short-length retail bins — sold at discount for small projects, craft work, and picture frames | ~15% of total waste stream |
| Sawdust & Shavings | Local farms in Dakota and Scott counties — used for animal bedding and composting | ~55% of total waste stream |
| Metal (nails, screws, bolts, hardware) | Local scrap metal recycler — ferrous metals separated from non-ferrous for maximum recovery value | ~5% of total waste stream |
| Unusable Wood Scraps (under 12 inches, damaged) | Chipped for landscaping mulch and delivered to municipal composting facilities | ~20% of total waste stream |
| Non-Wood Debris (concrete, drywall, insulation from deconstructions) | Separated on-site and sent to appropriate recycling or disposal facilities | ~5% of total waste stream |
Current Landfill Diversion Rate: 98%+
The remaining 2% consists of contaminated material (paint, adhesives, chemical treatments) that cannot be safely recycled or composted. We are actively researching alternatives for this fraction, including thermal processing options that could recover energy value.
How We Identify Species in Reclaimed Lumber
Accurate species identification is one of the most critical skills in reclaimed lumber processing. Unlike new lumber that arrives with species labels and mill stamps, reclaimed wood often has no documentation. A century of use, weathering, and finishing can obscure the visual characteristics that would otherwise make identification straightforward.
Our grading team uses a multi-step identification process that combines visual analysis, physical testing, and experience to determine species with high confidence. Correct identification matters because it determines structural grade, market value, and the processing parameters we apply during milling.
Step 1: End-Grain Analysis
A fresh cross-cut reveals the end grain — the pattern of growth rings, pores, and rays. Ring-porous species (oak, ash, elm) show clearly different pore sizes in early and late wood. Diffuse-porous species (maple, poplar) have uniform pore distribution. Softwoods (pine, fir) show no visible pores at all. This is the most reliable initial sorting step.
Step 2: Weight and Density
Species have characteristic densities. A board that feels noticeably heavy for its size may be oak, hard maple, or old-growth heart pine. A board that feels light is more likely white pine or poplar. We use a weight-per-volume comparison against reference samples to confirm visual identification.
Step 3: Surface and Odor
A fresh surface (from a test cut or sanding) reveals the natural color and odor of the wood. Red oak has a distinctive vinegar-like smell. White pine produces a sweet, resinous scent. Douglas fir has a sharp, aromatic odor. These sensory clues, combined with visual and weight analysis, typically allow confident identification.
Step 4: Magnification & Chemical Tests
For ambiguous cases, we use 10x magnification to examine cellular structure and, when necessary, chemical spot tests. A drop of sodium hydroxide solution on white oak will turn the surface dark purple (due to tannin content), while red oak produces a lighter reaction. These tests are definitive for the most common identification challenges.
What We Can Mill for You
Our milling shop is set up to handle the full range of reclaimed lumber processing — from basic surfacing to complex custom profiles. Here is a detailed look at the milling services we offer and the specifications we can achieve.
S2S / S4S Surfacing
Surfacing two sides (S2S) or four sides (S4S) to create uniform thickness and width. We surface rough reclaimed boards to within 1/32-inch of target dimensions. Available for boards up to 20 inches wide and 8 inches thick.
Tongue-and-Groove Flooring
Custom-profiled tongue-and-groove flooring in 3/4-inch, 1-inch, and 5/4-inch thicknesses. Widths from 3 inches to 12 inches. We test-fit profiles from each batch to verify consistent engagement across the full run.
Shiplap Siding & Paneling
Shiplap profiles with 1-inch overlap for wall paneling, ceiling treatments, and exterior siding. Available with square edge or V-groove detail. Standard thicknesses: 3/4-inch and 5/4-inch.
Resawing
Converting thick stock into thinner boards on our resaw bandsaw. This maximizes material yield — an 8/4 board becomes two 4/4 boards, doubling the usable square footage from a single piece. Maximum resaw capacity: 20 inches.
Skip Planing
A light pass through the planer that removes surface dirt and roughness while preserving the character and patina of the original wood. Skip planing is popular for accent walls and rustic applications where a clean but not pristine surface is desired.
Beam Cleaning
Surfacing exposed faces of beams and timbers while leaving concealed faces rough. Options include two-face, three-face, or full four-face surfacing. We can also wire-brush beams to clean the surface while preserving the hand-hewn texture.
What Sets Our Processing Apart
Reclaimed wood demands a different skill set, different equipment, and a different mentality than working with new lumber. Here is what that looks like in practice.
Why Reclaimed Processing Is Different
New lumber comes off the mill uniform and predictable. Reclaimed lumber does not. Every board has a unique history — different species may be mixed in a single lot, dimensions vary from decades of use, and hidden metal can destroy a planer blade in an instant. Processing reclaimed wood well requires slower feed rates, sharper tooling, and a team that knows how to read grain direction on a board that has been weathered, torqued, and fastened for a century.
Equipment Built for the Job
Standard woodworking equipment struggles with reclaimed lumber. The density of old-growth wood dulls blades faster. Case-hardened surfaces resist standard planer settings. We run carbide-tipped tooling, maintain aggressive sharpening schedules, and use feed rates calibrated for the higher density of aged timber. Our resaw bandsaw is specifically set up to handle the stresses of cutting through wood that has dried and seasoned for decades.
Zero-Waste Processing
Milling generates waste: off-cuts, sawdust, and trim. In our shop, none of it reaches a landfill. Usable off-cuts are sorted into short-length bins for small projects and craft work. Sawdust is collected and sent to local farms for composting and animal bedding. Metal scraps go to recycling. The goal is 100 percent material utilization — and we are consistently above 95 percent.

Common Questions About Our Process
How long does custom milling take?
Typical turnaround for custom milling is 5 to 10 business days, depending on order size and complexity. Simple surfacing (S2S or S4S) on stock we already have graded can often be completed within 3 days. Tongue-and-groove profiling, resawing, and custom dimensions require additional time for setup and quality verification.
Can you match existing reclaimed material in my home?
In most cases, yes. Bring us a sample of the existing material, and we will identify the species, grain pattern, and approximate age. We will then search our inventory for matching material. Exact color matching depends on species and finish, but we can typically find wood with compatible grain density and character.
Is your reclaimed lumber safe for food-contact surfaces?
We test material from pre-1978 structures for lead paint before processing. Material confirmed free of paint contamination and chemical treatment is suitable for food-contact applications when finished with an appropriate food-safe finish. We can advise on which lots in our inventory are verified clean for this use.
Do you guarantee your material is nail-free?
Every board goes through two rounds of electromagnetic metal scanning — once before de-nailing and once after. We are confident in our de-nailing process, and we stand behind it. If you find metal in any board we sold as de-nailed, contact us and we will replace the board and reimburse any blade damage.
