The average price to Install a Wood Subfloor noted above is cost data to compare a contractor’s estimate with doing it yourself.

How much does it cost to install a wood subfloor? A carpenter charges $1,164 to install a basement subfloor, but a homeowner can do the job for $650 and save 44 percent. 

A sound subfloor is needed when you’re laying carpet, vinyl, laminate or engineered hardwood on a cement basement floor so the surface is warm, dry and resilient. DRIcore® is a modular system of 2-foot square engineered wood panels bonded to a rigid moisture-resistant polyethylene sheet with molded-in dimples.

These dimples create airspace between the cement and subfloor to prevent the transfer of cold air and help dry up condensation. These panels are installed as a floating subfloor and press-fit together without nails or glue.

Here’s a breakdown of the numbers. A carpenter will install a subfloor in an 18-by-20-foot basement room for $1,164, which includes the labor and material. If you have carpentry experience, you can do the job for $650, the cost of the panels and leveling squares designed to slide under the panels to adjust for uneven areas. You’ll pocket a 44 percent saving if you do it yourself. You’ll need basic tools including a power saw, power drill, carpenter’s square, level, hammer, pry bar, measuring tape and scrap wood as a tapping block.

These materials are heavy so they’re not easy to transport and move around. Storing the material before installing it can be an issue because it should be in a dry level area.
