Building Deconstruction & Material Recovery
We do not demolish buildings — we deconstruct them. Our team carefully dismantles structures board by board, salvaging up to 95% of usable materials and keeping hundreds of tons of lumber out of landfills.

What Happens During a Pre-Deconstruction Assessment
Every deconstruction project begins with a thorough on-site assessment. This is a free service — we invest time upfront to evaluate the structure so we can provide an accurate proposal and set proper expectations for material recovery, timeline, and cost.
Structural Evaluation
We assess the overall structural condition, load-bearing elements, and identify areas that require shoring or special handling during disassembly. Compromised areas are documented and factored into the work plan.
Material Inventory
We identify species, dimensions, and approximate quantities of all recoverable lumber. This includes framing, flooring, siding, trim, beams, and architectural elements. We estimate board footage for pricing.
Hazardous Material Screening
We visually screen for potential asbestos-containing materials (pipe insulation, floor tiles, vermiculite), lead paint (pre-1978 buildings), and other hazardous substances. Lab testing is coordinated if suspect materials are found.
Access and Logistics Planning
We evaluate site access for trucks and equipment, staging areas for sorted material, and proximity to neighbors and utilities. This information drives crew size, equipment needs, and scheduling.
Detailed Written Proposal
After the assessment, you receive a comprehensive written proposal including estimated recovery volumes, timeline, cost breakdown, tax deduction potential, and a comparison to standard demolition costs.
What We Deconstruct
We deconstruct a wide range of building types, each with unique material recovery potential. Here's what to expect from different structure categories.
Barns & Agricultural Buildings
Post-and-beam barns are the gold standard for deconstruction. The massive timbers, wide siding boards, and heavy flooring planks found in Minnesota barns are among the most sought-after reclaimed materials on the market. Many barns in the region date to the 1860s-1920s and contain old-growth species no longer commercially available.
Recovery Rate
85-95%
Timeline
1-2 weeks
Avg Recovery
5,000 - 25,000 board feet
Common Materials
Hand-hewn oak beams, pine siding, hardwood pegs, barn board, heavy timber framing
Pre-1960 Residential Homes
Older Twin Cities homes — particularly those built before 1960 — contain old-growth framing lumber, hardwood flooring, solid-wood millwork, and vintage hardware that have significant salvage value. Craftsman bungalows, Victorians, and mid-century homes yield especially desirable materials.
Recovery Rate
70-85%
Timeline
1-3 weeks
Avg Recovery
3,000 - 10,000 board feet
Common Materials
Oak flooring, fir framing, trim and moulding, doors, vintage hardware
Commercial & Industrial Buildings
Warehouses, factories, and mill buildings constructed with heavy timber framing yield massive beams, thick decking, and large quantities of dimensional lumber. Minneapolis has a rich industrial history, and many buildings being redeveloped contain exceptional structural timbers.
Recovery Rate
75-90%
Timeline
2-4 weeks
Avg Recovery
10,000 - 50,000+ board feet
Common Materials
Douglas fir timbers, heavy maple decking, industrial hardware, structural steel
Churches, Schools & Institutional Buildings
Historic institutional buildings often contain rare wood species, ornate millwork, stained glass, and architectural elements of exceptional craftsmanship. These buildings require careful deconstruction to preserve decorative elements alongside structural materials.

Timeline
2-4 weeks
Avg Recovery
5,000 - 20,000 board feet
Common Materials
Rare species millwork, ornate trim, pews, wainscoting, structural timbers
Deconstruction vs. Demolition
Demolition destroys. Deconstruction preserves. The difference matters — for the environment, for your wallet, and for the next generation of builders who will use these materials.
Careful, manual disassembly of the structure piece by piece, preserving materials for reuse
Rapid mechanical destruction using excavators and wrecking equipment
Up to 95% of usable materials are salvaged and enter the reclaimed supply chain
Virtually all materials are crushed and sent to landfill as mixed waste
Dramatically reduced landfill waste, lower carbon emissions, materials stay in circulation
Hundreds of tons of usable material sent to landfill, higher carbon footprint
Donated materials may qualify for a charitable tax deduction based on fair market value
No tax benefits — materials are waste, not donations
Takes longer than demolition — typically 1-4 weeks depending on structure size
Faster — large structures can be leveled in days
Often comparable to demolition when tax deductions and salvage value are factored in
Lower upfront cost but no material value recovery or tax benefits
Environmental Comparison: Hard Numbers
The environmental difference between deconstruction and demolition is measurable and significant. These figures are based on typical residential and commercial projects.
How We Deconstruct
Every deconstruction project follows a systematic process designed to maximize material recovery while maintaining safety and regulatory compliance.
Site Assessment
Our team inspects the structure to evaluate what materials can be salvaged, estimate recovery volumes, and identify any hazards (asbestos, lead paint, structural concerns). We provide a detailed written proposal.
Hazard Abatement
If hazardous materials are present, they are professionally abated before deconstruction begins. We coordinate with licensed abatement contractors to ensure full regulatory compliance.
Systematic Disassembly
Deconstruction proceeds from the top down and the inside out. Roofing is removed first, then interior finishes, followed by framing, siding, and finally the foundation. Every salvageable piece is carefully extracted.
Material Sorting & Grading
Recovered materials are sorted on-site or at our yard by species, dimension, and condition. Lumber is de-nailed, cleaned, and graded for its next use.
Site Cleanup
Once deconstruction is complete, we remove all remaining debris and leave the site clean and ready for its next chapter. Non-salvageable waste is responsibly disposed of or recycled.
Asbestos, Lead Paint & Hazardous Material Protocols
Most buildings constructed before 1980 contain some form of hazardous material — asbestos in insulation, floor tiles, or siding; lead paint on interior and exterior surfaces; or other regulated substances. We take a thorough, compliant approach to identification and abatement.
Pre-Project Inspection
A licensed inspector conducts a thorough survey of the building, collecting samples of suspected materials for laboratory analysis. This is a required step before any permit is issued in Minneapolis and St. Paul.
Licensed Abatement
If hazardous materials are confirmed, we coordinate with Minnesota-licensed abatement contractors for professional removal. Asbestos is wetted, contained, and transported to approved disposal facilities. Lead paint is either encapsulated or removed depending on location.
Air Monitoring
During abatement, air monitoring ensures that fiber and particulate levels remain within regulatory limits. Final clearance testing confirms the building is safe for deconstruction to proceed.
Documentation
All abatement activities are documented with inspection reports, lab results, abatement work plans, waste manifests, and clearance reports. This documentation is critical for regulatory compliance and future site use.
Timeline Expectations by Building Size
Deconstruction takes longer than demolition — but the material recovery, environmental impact, and financial benefits make the extra time worthwhile. Here are typical timelines by building size.

What We Salvage
We recover everything that can be reused. The goal is simple: as close to zero waste as possible.
Dimensional Lumber
Studs, joists, rafters, and framing lumber in all standard dimensions. Softwood and hardwood species.
Beams & Timbers
Large structural beams, posts, and timbers — often the most valuable material in older buildings.
Flooring
Hardwood strip and plank flooring, including oak, maple, and heart pine. Carefully removed to preserve tongue-and-groove profiles.
Siding & Sheathing
Clapboard, shiplap, board-and-batten, and plank siding. Weathered exterior wood is highly sought for accent walls.
Doors & Windows
Vintage solid-wood doors, window frames, and trim. Architectural salvage items with historical character.
Hardware & Fixtures
Hinges, handles, brackets, nails, and architectural metalwork. Even small hardware has value to restorers.
Permitting & Regulatory Information
Deconstruction requires permits, just like demolition. We handle the entire permitting process, but here's what you should know about requirements in different jurisdictions.
City of Minneapolis
A building permit is required for deconstruction, similar to demolition. The city requires a waste management plan documenting how materials will be diverted from landfill. Minneapolis has a strong sustainability focus and generally supports deconstruction over demolition. Permit processing typically takes 2-4 weeks.
City of St. Paul
St. Paul requires a demolition/deconstruction permit issued by the Department of Safety and Inspections. An asbestos survey by a licensed inspector is mandatory before the permit is issued. The city offers expedited processing for projects with documented waste diversion plans.
Hennepin County
Unincorporated areas of Hennepin County require permits through the county building department. The county has active construction waste diversion goals and provides resources for property owners choosing deconstruction over demolition.
Greater Minnesota / Rural
Permit requirements vary by township and county. Many rural communities have less stringent requirements for agricultural building removal (barns, outbuildings). We research and obtain all necessary permits as part of our project management for every deconstruction job.
Site Preparation & Post-Deconstruction Cleanup
A well-prepared site leads to a faster, safer deconstruction. And a thorough cleanup means you get a site that's ready for whatever comes next — new construction, landscaping, or simply open space.
Site Preparation (Your Responsibility)
- Remove personal property and belongings from the structure
- Disconnect all utilities (electric, gas, water, sewer, cable)
- Provide site access for trucks and equipment staging
- Notify neighbors about the project and expected timeline
- Obtain any HOA or neighborhood approvals if applicable
Post-Deconstruction Cleanup (Our Responsibility)
- Remove all debris, loose nails, wood scraps, and dust
- Sweep and rake the footprint area to a clean condition
- Haul non-salvageable waste to appropriate recycling or disposal
- Leave foundation in place (or remove for additional fee)
- Final walkthrough with property owner to confirm satisfaction
- Provide material recovery report documenting what was salvaged

Where We Work
Our deconstruction crews operate throughout the Twin Cities metro and across greater Minnesota. We have completed projects as far as Duluth, Rochester, and St. Cloud. For structures with significant salvage value, we will travel even further.
Best Candidates
While we can deconstruct nearly any structure, certain buildings yield the highest material recovery and provide the greatest environmental and economic return.
Barns & Agricultural Buildings
Barn wood and timbers are among the most sought-after reclaimed materials. Post-and-beam barns are ideal for deconstruction.
Pre-1960 Homes
Older homes contain old-growth lumber, hardwood flooring, and millwork that cannot be sourced from new timber.
Warehouses & Factories
Industrial buildings yield heavy timbers, thick decking, and large quantities of framing lumber.
Churches & Schools
Historic institutional buildings often contain rare wood species, ornate millwork, and exceptional craftsmanship.
Potential Tax Deductions
Property owners who donate salvaged materials through a qualified deconstruction project may be eligible for a federal tax deduction based on the fair market value of the donated materials. In many cases, the tax benefit alone can offset a significant portion of the deconstruction cost.
We work with qualified appraisers who can assess the fair market value of recovered materials and provide the documentation needed for IRS compliance. Consult your tax advisor for specific guidance on deduction eligibility.
Based on fair market value of donated materials
Qualified appraisals and documentation provided
Deduction often covers 50-100% of deconstruction cost
Residential vs. Commercial Deconstruction
Residential Deconstruction
Residential projects typically involve single-family homes, duplexes, garages, and outbuildings. These structures are smaller but often contain high-value materials — old-growth hardwood flooring, vintage trim, solid-wood doors, and character-rich framing lumber.
- Crew size: 2-4 workers
- Duration: 1-3 weeks typically
- Permits: City building permit required
- Tax deduction: Available for material donations
- Best value: Pre-1960 homes with original materials
Commercial Deconstruction
Commercial projects involve larger structures — warehouses, factories, retail buildings, schools, and churches. These projects yield significantly more material but require larger crews, more equipment, and longer timelines. They also tend to have more complex permitting and hazardous material considerations.
- Crew size: 4-10 workers
- Duration: 2-8 weeks typically
- Permits: Building permit + environmental review
- Tax deduction: Available; larger material value = larger deduction
- Best value: Heavy-timber warehouses and industrial buildings
Completed Deconstruction Projects
Here are detailed accounts of three recent deconstruction projects that illustrate what our process looks like in practice and the results we achieve.
The Goodhue County Dairy Barn (1887)
A three-level dairy barn built in 1887, located south of Red Wing. The barn had a hand-hewn white oak timber frame with pine board-and-batten siding and a gambrel roof. The structure was no longer in agricultural use and the owner planned to demolish it. After our assessment, we proposed deconstruction with a material donation for tax purposes.
Results
Recovered 12,000 board feet of white oak timber, 4,000 sq ft of pine siding, and 200+ hand-forged hardware pieces. The owner received documentation supporting a five-figure tax deduction — significantly more than a demolition company quoted for removal. The oak beams became mantels, restaurant tables, and structural accents in three different Twin Cities projects.
16,000+ board feet recovered | 3 weeks on-site | 92% material recovery rate
The Northeast Minneapolis Warehouse (1912)
A 15,000 sq ft warehouse in the Arts District being redeveloped into residential lofts. The developer needed the building cleared for new construction but wanted to preserve materials from the original structure. Heavy Douglas fir timber framing, maple factory flooring, and industrial steel hardware were identified during assessment.
Results
Recovered 22,000 board feet of Douglas fir timbers (some measuring 14" x 14" x 30'), 8,000 sq ft of maple factory flooring, and 2 tons of industrial hardware including cast iron columns and steel brackets. The developer retained a selection of beams for decorative use in the new loft units. The remaining material entered our supply chain.
30,000+ board feet recovered | 4 weeks on-site | 88% material recovery rate
The Kenwood Craftsman Home (1924)
A 2,400 sq ft Craftsman bungalow in the Kenwood neighborhood of Minneapolis, slated for removal to make way for new construction. The home contained original oak hardwood flooring, fir framing, ornate oak woodwork, and four-panel solid-wood interior doors — all characteristic of the Craftsman era.
Results
Recovered 1,800 sq ft of original 3/4" white oak flooring in excellent condition, 800 linear feet of oak crown moulding and baseboard, 12 original four-panel doors, vintage brass hardware, and 6,000 board feet of old-growth fir framing. The oak flooring was resold as-is to a homeowner in St. Paul restoring a similar-era home. The moulding was used to match historic profiles in a preservation project.
8,000+ board feet recovered | 2 weeks on-site | 82% material recovery rate
Frequently Asked Questions About Deconstruction
How much does deconstruction cost compared to traditional demolition?
The upfront cost of deconstruction is typically 10-30% higher than demolition because it is more labor-intensive and takes longer. However, when you factor in the fair market value tax deduction for donated materials and the salvage value of recovered lumber, deconstruction is often cost-neutral or even cheaper than demolition in total. For a typical 2,000 sq ft home, deconstruction might cost $15,000-$25,000 upfront, but the tax deduction could offset $10,000-$20,000 of that cost.
Who is responsible for obtaining deconstruction permits?
We handle the entire permitting process as part of our service. We prepare and submit all required applications to the relevant jurisdiction (Minneapolis, St. Paul, county, or township), coordinate any required inspections, and ensure all regulatory requirements are met before work begins. Permit costs are included in our project quote.
What happens if asbestos or lead paint is found during the assessment?
Asbestos and lead paint are common in buildings constructed before 1980. If our assessment identifies potential hazardous materials, we coordinate with licensed abatement contractors to have the material professionally tested and, if confirmed, safely removed before deconstruction begins. Abatement costs are quoted separately and are always performed by Minnesota-licensed abatement professionals. We do not proceed with deconstruction until all hazardous materials are cleared.
Can I keep some of the salvaged materials for my own use?
Absolutely. Many property owners want to keep specific materials — a favorite beam for a mantel, original flooring for a new project, or vintage doors and hardware. During the assessment phase, we work with you to identify which materials you want to retain. We set those aside during deconstruction and can even process them (planing, de-nailing, finishing) for you as part of the project.
How does the tax deduction for donated materials work?
When salvaged materials are donated to a qualifying 501(c)(3) nonprofit organization, the property owner may be eligible for a federal charitable tax deduction based on the fair market value of the donated materials. The fair market value is determined by a qualified appraiser — not by us and not by the nonprofit. For donations exceeding $5,000, IRS Form 8283 (Noncash Charitable Contributions) must be filed with your tax return. We coordinate the appraisal and documentation process. Consult your tax advisor for guidance specific to your situation.
Do you deconstruct the entire building, or just the parts with valuable lumber?
We deconstruct the entire structure. Our process removes all salvageable materials systematically — lumber, flooring, siding, doors, windows, hardware, and architectural elements. Non-wood materials (drywall, insulation, roofing, concrete) are separated for appropriate recycling or disposal. We do not cherry-pick high-value materials and leave the rest for you to deal with.
What condition is the site left in after deconstruction?
We leave the site clean and clear. After all materials are removed, we clean up all debris, loose nails, small wood scraps, and dust. The foundation is typically left in place unless removal is specifically requested (foundation removal is a separate service involving concrete breaking and hauling). The site is ready for grading, new construction, or landscaping upon our departure.
Is deconstruction safe for the surrounding neighborhood?
Deconstruction is significantly safer and less disruptive for neighbors than demolition. There is no heavy equipment crushing materials and generating clouds of dust. No wrecking balls or excavators shaking the ground. Noise levels are comparable to normal construction activity. We maintain clean, organized work sites and follow all OSHA safety protocols. Surrounding structures, utilities, and landscaping are protected throughout the process.
Can you deconstruct a building that is partially collapsed or structurally compromised?
Yes, but it requires additional safety measures. Our assessment evaluates structural integrity and identifies areas of concern. We use temporary shoring, bracing, and engineered fall-zone planning to safely work on compromised structures. In some cases, the most compromised sections may need to be mechanically removed (similar to demolition) before manual deconstruction can proceed on the remaining structure. Material recovery rates may be lower from severely damaged buildings.
How far will you travel for a deconstruction project?
Our primary deconstruction service area is the Twin Cities metro and greater Minnesota. We regularly travel to Duluth, Rochester, St. Cloud, Mankato, and throughout the southern Minnesota farm country where barns are most plentiful. For structures with exceptional salvage value — large post-and-beam barns, rare species timber frames, historic buildings — we will travel to western Wisconsin, northern Iowa, and eastern South Dakota. Travel costs for distant projects are built into the project quote.
