Sagging Floor Repair in Baton Rouge

Foundation Repair Baton Rouge is a foundation repair company with 20 years of industry experience, serving Baton Rouge and the Capital Region, and sagging floor repair is one of the most common calls from owners of older raised homes. A floor that dips in the middle of a room, bounces when you walk, or rattles the china cabinet is telling you something underneath has given up — a joist, a girder, or the support under it.

Sagging floor repair typically costs $1,500–$8,000, depending on the span, how much framing is damaged and how easy the crawl space is to work in.

Finding the cause

We take floor readings in the affected rooms, then go underneath. The usual causes are joists spanning too far between supports (common in older homes and additions), joists notched or cut for plumbing and ductwork, rot from a damp crawl space, and girders or piers that have settled. Each one has a different fix, so the diagnosis matters more than the lift.

How we fix it

• Sistering: new lumber fastened full-length alongside weakened joists.
• New girder and piers: a beam added under the middle of a long span, carried on new concrete piers on footings.
• Adjustable supports: steel posts on concrete pads under an existing girder, fine-tuned after installation.

We shore the floor while we work and lift gradually so plaster and tile don’t crack. If rot is the cause, the moisture problem gets addressed too — see crawl space repair. If the whole house is out of level rather than one room, you need house leveling or pier and beam repair.
