Sagging Floor & Wood Repair in Bettendorf
Sagging, sloping, or bouncy floors in Bettendorf usually mean a failed joist, beam, or support below. We find the real cause and fix it for good.
Why It Sags
Why Bettendorf Floors Sag — and How We Fix Them
A floor that slopes or bounces is a structural message: a joist has rotted, a beam is undersized, a sill plate has failed, or a support post has settled. On Bettendorf’s hillside and bluff-side lots, drainage and soil movement often play a role. We diagnose what actually failed and repair it so the floor stays level for good.
What We Do
What We Repair Below the Floor
Floor Joist Repair & Sistering
Reinforcing or “sistering” cracked, sagging, or undersized joists, and replacing those that are too far gone.
Beam & Girder Replacement
Replacing failing main beams and girders, and adding properly sized support where the original was undersized.
Sill Plate & Rot Repair
Cutting out water-damaged sill plates and rotted framing and rebuilding with treated, properly flashed material.
Support Posts & Jacks
Adding or replacing support posts and adjustable columns on proper footings to carry the load and re-level the floor.
Root Cause
Often It Starts With Water
Our Philosophy
A surprising amount of structural wood damage traces back to moisture — a wet crawl space, poor drainage, or a foundation leak quietly rotting the wood above it. We look for that root cause so the new framing doesn’t end up failing the same way. Sometimes the real fix is drainage or waterproofing →

A soft floor often isn’t the disaster it feels like
A floor that bounces or feels soft makes people fear the worst. Often it’s a single under-supported joist, a missing mid-span support, or subfloor — not a failing structure. We figure out what’s actually moving before anyone talks about tearing out floors.
