Step 01

Sourcing &
Acquisition

Every piece of reclaimed lumber starts at a demolition or deconstruction site. Our sourcing team evaluates over 200 potential projects per year and selects the ones that offer the best combination of material quality, volume, and logistical feasibility. We have built relationships with demolition contractors, property developers, and municipal agencies across six New England states.

We prioritize deconstruction — the careful, sequential disassembly of a structure — over demolition whenever possible. Deconstruction yields higher-quality lumber with less damage, more intact boards, and better species preservation. It also diverts significantly more material from landfills. On average, a well-planned deconstruction recovers 85% of reusable lumber compared to only 15-20% from conventional mechanical demolition.

Our sourcing network includes relationships with demolition contractors, property developers, municipal governments, renovation companies, and even homeowners. We also accept walk-in sellers who bring material to our yard at 37 Linden St, Medford, MA 02155. Every potential source is evaluated against five criteria: species quality, volume availability, structural condition, logistical accessibility, and environmental compliance.

Site Evaluation

Our team visits each potential source site to assess material type, species, volume, condition, and accessibility before committing resources. We photograph representative samples, measure key dimensions, and estimate recoverable board footage using standardized yield calculations.

Species Identification

On-site identification of wood species — heart pine, cypress, oak, Douglas fir, chestnut, and more — determines processing requirements and market value. Our sourcing crew carries field identification kits including hand lenses, hardness testers, and reference samples for visual grain matching.

Volume Estimation

Accurate board-foot estimates help us plan logistics, processing schedules, and inventory allocation before the first truck arrives. We use a combination of physical measurement, photographic documentation, and yield-factor databases to project recoverable volume within 10% accuracy.

Environmental Compliance

We verify all permits, check for hazardous materials (lead paint, asbestos, CCA-treated wood), and ensure the project meets environmental regulations. Any site with confirmed lead paint or asbestos requires documented abatement before we begin material recovery.

Logistics Planning

Before committing to a salvage project, we plan the full logistics chain: truck routing, loading equipment needs, staging areas, and processing schedule at our facility. For large projects generating 10,000+ board feet, we develop a phased extraction plan.

Chain of Custody Documentation

Every salvage acquisition is documented with source site address, property owner information, demolition permit numbers, species identification records, and estimated volume. This documentation forms the foundation of our FSC chain-of-custody system.

Species Expertise

Species Identification Protocol

Accurate species identification is fundamental to our operation. It determines structural properties, workability, market value, and appropriate end use. Our multi-step identification process ensures you get exactly the species you order.

1

Visual Grain Analysis

Trained graders examine end grain, face grain, and ray patterns under magnification. Each species has distinctive grain characteristics — oak has prominent rays, heart pine has dense growth rings, chestnut has ring-porous structure. This is the primary identification method and is accurate for over 90% of common species.

2

Color & Patina Assessment

The natural color of the heartwood and sapwood, along with how the wood has aged and patinated, provides additional species clues. Heart pine develops a distinctive amber-to-honey tone, white oak ages to a silvery gray, and American chestnut develops a warm brown with reddish undertones.

3

Weight & Density Testing

Each species has a characteristic density range. A sample board is weighed and measured to calculate its density in pounds per cubic foot, then compared against reference values. Douglas fir averages 34 lbs/cf, white oak averages 47 lbs/cf, and heart pine ranges from 38-52 lbs/cf.

4

Hardness Verification

Janka hardness testing measures the force required to embed a steel ball into the wood surface. This provides a numerical confirmation of species identification and helps assess suitability for specific applications like flooring where hardness determines durability.

5

Scent & Machining Characteristics

When freshly cut, many species have distinctive scents — cedar is aromatic, oak has a sharp tannic smell, and pine releases resin. Machining characteristics like how the wood planes, sands, and accepts finishes provide further confirmation during processing.

6

Reference Sample Comparison

Our facility maintains a reference library of confirmed species samples from known sources. Uncertain identifications are compared side-by-side with reference samples under identical lighting. For rare species, we may consult university forestry departments.

Step 02

Processing & Milling

Our processing facility is the heart of the operation. This is where raw salvaged timber is transformed into clean, graded, ready-to-use reclaimed lumber. Every board passes through multiple stations, each designed to maximize material quality and recovery.

De-Nailing

Industrial pneumatic de-nailers remove all embedded metal — nails, screws, staples, bolts, and brackets. Our operators have a trained eye for finding hidden fasteners that automated systems miss. Every board is hand-checked after de-nailing. A single board may contain 20-50 nails depending on its original use, and each must be found and removed. Our de-nailing crew processes 800-1,000 board feet per operator per day.

Metal Detection

After de-nailing, each board runs through a commercial metal detector. Any remaining metal fragments — broken nail tips, wire, or embedded hardware — are flagged and removed. This step protects our planer blades and ensures the final product is completely metal-free. Our detector sensitivity is calibrated to find ferrous fragments as small as 1mm in diameter.

Initial Grading

Trained graders evaluate each board for species, structural integrity, defects, character markings, and potential end use. Boards are sorted into grade categories that determine their processing path — structural, character, flooring, or resaw stock. Approximately 62% of incoming material grades as commercially resalable, 15% as utility, and 10% goes to donation.

Kiln Drying

Our on-site kiln brings reclaimed lumber to target moisture content (typically 6-8% for interior use, 12-14% for exterior). Heat treatment also eliminates pests and pathogens, meeting ISPM-15 certification requirements. Each kiln cycle takes 5-14 days depending on species, thickness, and starting moisture content.

Planing & Surfacing

A 24-inch industrial planer surfaces boards to specified thickness with tight tolerances. We offer S1S, S2S, S3S, and S4S surfacing options depending on the application. Rough-sawn faces can be preserved on request for character. Planer blades are inspected every 2,000 board feet and replaced as needed.

Resawing & Custom Milling

Our resaw can take thick timbers and slice them into thinner boards, maximizing yield from each piece. Custom tongue-and-groove profiles, shiplap, V-groove, bead board, and other milling profiles are available for flooring and wall cladding. Our moulder can match existing profiles from samples for historic restoration work.

Moisture Management

Moisture Testing
Protocol

Moisture content is one of the most critical factors in lumber performance. Wood that is too wet will shrink, warp, and cup as it dries in place. Wood that is over-dried may crack or become brittle. Our moisture testing protocol ensures every board is at the correct MC for its intended application.

We use both pin-type and pinless moisture meters for comprehensive testing. Pin-type meters measure MC at specific depth points and are essential for confirming that kiln drying has penetrated to the board core. Pinless meters provide rapid surface readings for pre-screening large quantities quickly without leaving pin holes in finished surfaces.

Every kiln-dried batch is tested at a minimum of three points per board: center, one-third from each end. Readings are documented on batch tracking sheets that travel with the material from kiln to inventory to shipping. Customers receive MC documentation with every kiln-dried order.

Target MC by Application

Interior Flooring6-8% MC

Critical for dimensional stability under heating systems. Acclimatization recommended before installation.

Interior Wall Cladding6-8% MC

Prevents seasonal movement and gapping in climate-controlled environments.

Furniture & Millwork6-7% MC

Tightest tolerance range. Requires precise kiln scheduling and post-kiln conditioning.

Exterior Siding12-14% MC

Equilibrium MC for exterior exposure in New England climate.

Structural Beams12-15% MC

Air-dried material often meets this range without kiln treatment.

Exterior Decking14-16% MC

Higher MC acceptable with good airflow and drainage.

Step 03

Quality Control &
Grading Standards

Grading reclaimed lumber is fundamentally different from grading new lumber. Our grading team has over 40 combined years of experience evaluating salvaged timber. They assess each piece across multiple dimensions to ensure you get exactly what you order.

We follow NHLA (National Hardwood Lumber Association) standards adapted for reclaimed material, with additional criteria specific to the unique properties of salvaged wood. Our grading system accounts for both structural performance and visual character — because with reclaimed lumber, those nail holes and patina are features, not defects.

Every board receives a grade stamp indicating species, grade, moisture content status (air-dried or kiln-dried), and dimensions. This standardized system allows architects and engineers to specify our products with the same confidence they have when specifying new lumber.

Our Grading Scale

Multi-Point Inspection

What We Check on Every Board

Species Verification

Positive identification of wood species using grain pattern analysis, weight, hardness testing, and visual examination by trained graders. Species determines structural properties, workability, and value.

Moisture Content

Pin-type and pinless meter readings at multiple points on each board. Interior-use lumber is kiln-dried to 6-8% MC. Exterior-use lumber is dried to 12-14% MC. Readings are documented per batch.

Structural Integrity

Evaluation for cracks, splits, checks, rot, insect damage, and cross-grain weakness. Boards with structural concerns are either downgraded, recut to salvage usable sections, or diverted to non-structural use.

Metal-Free Confirmation

Post-processing metal detection scan confirms zero remaining embedded metal. This protects end-user equipment (planers, saws, routers) and ensures safety for all downstream applications.

Dimensional Accuracy

Thickness, width, and length measurements verified against order specifications. Tolerances held to +/- 1/16 inch on surfaced dimensions. Any boards outside tolerance are resurfaced or replaced.

Visual Character Grading

Assessment of nail holes, patina, saw marks, mineral staining, weathering patterns, and other character features. Grades assigned per our published grading scale to match customer expectations.

Step 04

Packaging &
Delivery

The final step is getting your order to you safely. We invested early in building our own transportation fleet because we saw too much reclaimed lumber damaged by careless third-party haulers. Owning the trucks means we control the last mile — and that last mile matters.

Every order is banded, stickered (with spacer sticks between layers for airflow), and wrapped for transit protection. Load securement follows DOT standards with appropriate blocking, bracing, and strapping for the specific material being transported.

Our drivers are trained in proper lumber handling and understand the value of the material they carry. Every delivery includes a signed bill of lading documenting species, quantity, grade, and condition at delivery.
