Warning signs
- Floors that bounce when you walk across them
- A dip near the center of a room, a tub or the refrigerator
- Doors that stick or swing open on their own
- Cracks in tile or drywall above doorways
- Gaps between the floor and baseboards
What causes sagging floors
Moisture damage is the most common cause: years of humid air soften joists and sills and invite rot and termites. Many older homes also have joists or beams spaced farther apart than modern codes allow. Block piers set on shallow footings can sink into clay soil after wet seasons, and heavy tubs, kitchen islands or bookcases added later put extra load on old framing.
How we fix it
We start with a free inspection, measuring floor levels and checking the wood with a moisture meter. Repairs may include:
- Adjustable steel support posts on new concrete footings to shorten spans and lift sagging areas
- Sistering joists: bolting new lumber alongside damaged joists
- Beam replacement where the main girder has cracked or rotted
- Sill plate repair where the wood resting on the foundation has decayed
We lift floors gradually to avoid cracking drywall or tile, then lock the supports in place.
Stop it from happening again
Structural repair fixes the damage; moisture control prevents it from returning. Most of our floor repair jobs are paired with a vapor barrier or full encapsulation so the new wood stays dry. Steel support systems come with a written warranty, and we provide photos and a repair summary you can keep for insurance or a future sale.
