Frequently Asked Questions
How do I know if my subfloor is damaged?
Common signs of subfloor damage in Texas homes include soft or spongy spots when walking, visible sagging or dipping, persistent squeaking, musty odor from mold growth, and staining or discoloration on the surface. Bathroom subfloors around toilets and tubs are the most common failure points. If your tile is cracking without foundation issues or your hardwood is cupping in specific areas, the subfloor underneath may be deteriorating from moisture exposure.
How much does subfloor repair cost in Texas?
Subfloor repair in Texas costs $200 to $1,500 for localized damage and $5-$12 per square foot for larger replacement areas. A small patch around a leaking toilet costs $200-$500. Full bathroom subfloor replacement runs $500-$1,500. Joist repair costs $100-$300 per joist. A 200 square foot area costs $1,000 to $2,400. These costs do not include replacing the finish flooring on top, which is a separate expense.
What causes subfloor damage in Texas homes?
The most common cause in Texas is water damage from plumbing leaks, especially slow leaks under toilets, around tubs, and from dishwashers that go undetected for months. Pier and beam homes in Houston and East Texas are vulnerable to moisture rising from the crawl space. Termites cause significant subfloor damage throughout Texas, particularly in humid regions. Foundation settling in North Texas clay soils can crack slab-on-grade homes and damage plywood overlays.
Can subfloor repair be done without removing all the flooring?
For localized damage, a contractor can cut and remove only the section of finish flooring over the damaged subfloor area. The subfloor is repaired or replaced, then the finish floor patched to match. For widespread damage, removing all flooring in the room is more practical and ensures no hidden damage is missed. Carpet is the easiest to work around since it can be pulled back and re-stretched. Tile and hardwood require more invasive removal.
Should I replace OSB or plywood subfloor?
Plywood is the preferred subfloor material in Texas. It handles moisture exposure better than OSB, which swells permanently when wet and does not dry flat. If your existing OSB subfloor has water damage, replacing the affected area with plywood is recommended. For small patches, match the thickness of the existing material. For full-room replacement, 3/4-inch tongue-and-groove plywood is the gold standard. CDX grade plywood provides the best balance of cost and moisture resistance.
Does homeowner insurance cover subfloor damage?
Texas homeowner insurance typically covers subfloor damage from sudden events like a burst pipe or appliance failure. Gradual damage from slow leaks, poor maintenance, or termite damage is generally excluded. If a covered event caused the damage, both the subfloor repair and finish flooring replacement are typically covered minus your deductible. Document all damage with photos immediately and file a claim before starting repairs. Many Texas contractors assist with insurance documentation.
