Subfloor Replacement

What This Service Involves

When water intrusion or rot has compromised a subfloor, patching is not enough and full replacement is the responsible fix. We remove the damaged decking, inspect the joists beneath, and install new structural sheathing rated for your conditions. Because moisture is relentless in the Northwest, we address the source and add protection to keep the new subfloor dry. The result is a sound, level base that supports your finished floor for decades.
