Reclaimed wood flooring is one of the most popular applications for salvaged lumber, and for good reason. Old-growth hardwood offers density, character, and visual warmth that no modern flooring product can match. A floor made from 19th-century heart pine or white oak tells a story with every plank — nail holes, saw marks, patina, and grain patterns that are genuinely unrepeatable. But installing reclaimed flooring requires more planning than dropping in a box of prefinished engineered planks.
Choosing the Right Species
Not all reclaimed wood makes good flooring. You need a species with sufficient hardness to withstand foot traffic, furniture, and daily wear. The Janka hardness scale is your primary reference. Heart pine rates around 1,225 lbf — harder than red oak (1,290 lbf) and significantly harder than modern southern yellow pine (690 lbf). White oak (1,360 lbf) and maple (1,450 lbf) are excellent choices for high-traffic areas. Cypress (510 lbf) is better suited for walls and ceilings.
Width matters too. Wider planks (5" to 12") showcase the wood's character but are more susceptible to seasonal movement. Narrower boards (3" to 4") are more dimensionally stable. For reclaimed flooring, we generally recommend widths between 4" and 8" as the best balance of aesthetics and performance.
Preparation and Acclimation
Reclaimed flooring boards must be properly processed before installation. This means de-nailing, planing to uniform thickness, and milling tongue-and-groove profiles. At Houston Lumber, we mill reclaimed flooring to 3/4" thickness standard, with custom thicknesses available for renovation projects matching existing floors.
Before installation, allow the flooring to acclimate in the room where it will be installed for at least two weeks. Stack it loosely with stickers between layers. The wood needs to reach equilibrium with the room's temperature and humidity — typically 6–9% moisture content for most indoor environments. Use a pin-type moisture meter to verify: the difference between the flooring and the subfloor should be no more than 2%.
Installation Considerations
Nail-down installation over a plywood subfloor is the gold standard for 3/4" solid reclaimed flooring. Use a pneumatic flooring nailer with 2" cleats spaced every 8 to 10 inches along each board. Reclaimed wood is harder than modern lumber, so adjust your nail pressure accordingly — too much pressure splits the tongues, too little leaves the boards loose.
Glue-down installation works for thinner reclaimed flooring (3/8" to 1/2") over concrete slabs. Use a moisture-curing urethane adhesive rated for solid hardwood. Floating installation is not recommended for solid reclaimed flooring due to the material's density and expansion characteristics.
Finishing is the final step. Many clients prefer a penetrating oil finish that soaks into the wood and highlights the natural grain without building a plastic-like film on the surface. Water-based polyurethane works well for high-traffic commercial applications. Whatever finish you choose, apply it after installation — prefinished reclaimed flooring loses much of its character when the edges are sealed before the boards are fitted together.
