Sagging Floor & Wood Repair in LeClaire

Sagging, sloping, or bouncy floors in LeClaire usually mean a failed joist, beam, or support below. We find the real cause and fix it for good.

Why It Sags

Why LeClaire Floors Sag — and How We Fix Them

A sloping or bouncy floor is structural: a rotted joist, an undersized beam, a failed sill plate, or a settled support post. In LeClaire’s riverside homes, moisture is a common culprit behind the rot. We diagnose what actually failed and repair the structure 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 →

Floors sloping or bouncing?

We’ll get under the floor, find what’s actually failing, and recommend the repair that fixes it for good — with a written estimate, usually within one business day.

Sister it or replace it?

Not every damaged joist needs to come out

Often we can sister a new member alongside a damaged joist — stronger, less demolition, less cost — when the damage is localized. Full replacement is sometimes necessary, but it shouldn’t be the default answer or the automatic line on an estimate.

“We had our basement joists replaced. Reasonable quote, booked in a timely manner, great communication with expectations and the contract. We could park a semi on our new floors. The owner was a doll.”

“Kyle came out and did a very thorough job of looking for possible cracks in the foundation, digging down to see below surface line — and informed us he didn’t see any obvious cracks.”
