Assessment Process

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.

Building Types

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

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

Know the Difference

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.

Method
Deconstruction

Careful, manual disassembly of the structure piece by piece, preserving materials for reuse

Demolition

Rapid mechanical destruction using excavators and wrecking equipment

Material Recovery
Deconstruction

Up to 95% of usable materials are salvaged and enter the reclaimed supply chain

Demolition

Virtually all materials are crushed and sent to landfill as mixed waste

Environmental Impact
Deconstruction

Dramatically reduced landfill waste, lower carbon emissions, materials stay in circulation

Demolition

Hundreds of tons of usable material sent to landfill, higher carbon footprint

Tax Benefits
Deconstruction

Donated materials may qualify for a charitable tax deduction based on fair market value

Demolition

No tax benefits — materials are waste, not donations

Timeline
Deconstruction

Takes longer than demolition — typically 1-4 weeks depending on structure size

Demolition

Faster — large structures can be leveled in days

Cost
Deconstruction

Often comparable to demolition when tax deductions and salvage value are factored in

Demolition

Lower upfront cost but no material value recovery or tax benefits

Our Process

How We Deconstruct

Every deconstruction project follows a systematic process designed to maximize material recovery while maintaining safety and regulatory compliance.

01

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.

02

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.

03

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.

04

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.

05

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.

Hazardous Materials

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.

Material Recovery

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.

Permits & Regulations

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.

Before & After

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

Ideal Projects

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.

Financial Benefits

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.

Cost Offset

Deduction often covers 50-100% of deconstruction cost

Project Types

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
Case Studies

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

FAQ

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.

Tear Down Responsibly. Build Up Sustainably.

If you have a building coming down, let us take it apart the right way. Every board we save is a board that stays out of the landfill and becomes part of someone's next project.
