Hardwood Floor Installation: Cost Factors and What to Expect Step by Step

Solid hardwood strip, usually around two and a quarter inches wide, is the classic New England floor. Wider planks look more modern but move more with humidity. Engineered hardwood has a real wood top layer over a stable plywood core and handles moisture changes better, which is why it is often used over concrete or radiant heat.

Prefinished boards arrive already stained and sealed, so the room is usable sooner. Unfinished boards are sanded and finished on site, which gives a smoother, more uniform surface but adds days and dust.

Wood needs to adjust to the moisture level of your home before it goes down. The boxes are brought into the room days ahead, depending on the product and the season. In a Massachusetts winter with the heat running, indoor air is very dry. In August it can be humid. Skipping acclimation is one of the most common causes of gaps and cupping later.

Hardwood needs a solid, flat wood subfloor. The installer checks for loose boards, squeaks and dips, adds screws where the subfloor moves, and lays a moisture barrier or underlayment paper. In older homes with plank subfloors, this is where most of the hidden work lives.

Boards usually run perpendicular to the floor joists for strength, and the layout is planned so the floor looks straight in the main sight lines of the room. Each board is blind nailed through the tongue with a flooring nailer, and the end joints are staggered so they do not line up.

For site finished floors, the floor is sanded flat, stained if desired, and coated with several layers of finish. Each coat needs drying time, and the room stays off limits during that stretch.

Baseboards and shoe molding go back on, thresholds and reducers are fitted where the hardwood meets tile or carpet, and doors are trimmed if the new floor is higher than the old one.

Species and grade of wood, width of the boards, prefinished versus site finished, the condition of the subfloor, stairs, and the number of doorways and transitions all affect price. Stairs in particular are slow, detailed work. Removing an old floor and repairing the subfloor can add meaningfully to the total.
