How Sill and Floor Joist Replacement in Spring, TX Works
Sill beams (also called sill plates) are horizontal framing elements that sit directly on top of your home’s foundation walls or piers. Floor joists span across the sill plates and support the subfloor and everything above it. When these components rot, crack, or shift, the floor above begins to sag, bounce, or warp.
Causes of Sill and Joist Damage in Spring, TX:
- Wood rot from high humidity or water intrusion
- Termite or pest damage in untreated or older wood
- Improper drainage causing persistent damp conditions under the home
- Shifting piers leading to unsupported joists
