Architects love specifying reclaimed wood — it photographs beautifully, clients love the story, and it checks every sustainability box. But specifying reclaimed lumber on drawings and successfully procuring it for a project are two very different things. The architects who use reclaimed wood most effectively understand its unique supply chain challenges and design around them. Here's what we at Houston Lumber wish every architect knew.
Availability Is the Starting Point, Not an Afterthought
Unlike new lumber, which can be ordered in virtually any species, dimension, and quantity with reliable lead times, reclaimed lumber inventory is supply-driven, not demand-driven. What's available depends on what buildings are being deconstructed at any given time. If you specify 3,000 square feet of 8-inch-wide reclaimed white oak flooring, there's no guarantee that quantity exists in one place, in one consistent batch.
The best practice is to engage your reclaimed lumber supplier during the design phase, not after construction documents are issued. At Houston Lumber, we regularly consult with architects early to identify what species, dimensions, and quantities we can realistically supply. This allows the architect to design around available material rather than specifying something that may require months of sourcing from multiple suppliers with inconsistent quality.
Writing Effective Specifications
A good reclaimed wood specification should include:
- Species — Be specific but flexible. Specify "reclaimed longleaf heart pine" if that's what you want, but consider listing acceptable alternatives (e.g., "or approved equal in reclaimed Douglas fir").
- Grade and character level — Describe the acceptable range of defects: nail holes (filled or open), checking, color variation, worm holes, and surface texture. Providing a reference sample or photo is invaluable.
- Dimensions and tolerances — Specify finished dimensions with realistic tolerances. Reclaimed wood often can't be milled to the tight tolerances of new lumber without excessive waste.
- Moisture content — Specify target MC (typically 6-8% for interior, 12-15% for exterior) and require kiln drying certification.
- Documentation — If pursuing LEED credits, specify the chain-of-custody documentation required.
Lead Times and Coordination
Budget more lead time for reclaimed lumber than you would for conventional materials. From initial inquiry to delivery, expect 4-8 weeks for standard items and 8-16 weeks for large quantities, unusual species, or custom milling. Long-lead procurement — ordering the reclaimed material early in the construction schedule, well before it's needed on-site — is standard practice for experienced reclaimed wood specifiers.
Coordinate with the general contractor on storage conditions. Reclaimed lumber should be delivered to a climate-controlled space (or at minimum a dry, covered area) and allowed to acclimate for at least 48 hours before installation. Site conditions during early construction — open walls, no HVAC — are not suitable for storing kiln-dried material.
Finally, build a relationship with a reliable supplier. The architects who have the smoothest experience with reclaimed wood are those who work with the same supplier repeatedly, developing mutual understanding of expectations, capabilities, and communication preferences. We welcome architects to visit our facility, review our inventory, and discuss upcoming projects. The earlier we're involved, the better the outcome.
