Key points
- Particle-board subfloors swell and lose strength when wet.
- The underbelly wrap can hold water like a bag under the floor.
- Supply lines run under the floor and freeze if skirting or heat tape fails.
- Fast drying matters even more than in site-built homes.
Common sources
- Frozen supply lines under the home — see frozen pipe
- Water heater and washer leaks
- Roof seams and windows
- Toilet and tub connections
What to do
- Shut off the water at the main.
- Check for sagging belly wrap — trapped water may need to be drained.
- Call us to map moisture and dry the floor system before the subfloor fails.
See winter pipe protection. Vault documents the damage, records daily moisture readings, scopes in Xactimate, and bills State Farm, USAA, Allstate, Farmers, and Bear River Mutual directly.
