Crawl space repair is structural work. It's about the skeleton of your home — the beams, joists, piers, and supports that hold up every floor you walk on. When those members rot, crack, settle, or fail, the entire house above feels it.
This isn't the same as crawl space encapsulation. Encapsulation controls moisture. Repair fixes the structural damage that moisture causes. Many homes need both — but the structural repair has to come first.
Adjustable steel support posts set on concrete footings. These replace failing wood posts, leaning block columns, and settled piers. They carry the load of the beam and floor system above, and they can be adjusted over time to bring floors back toward level.
When floor joists crack, rot, or weaken from moisture and age, we sister new joists alongside the damaged ones to restore strength. Joists that are too far gone get fully replaced. This is what stops the bounce and sag in your floors.
The main carrying beam runs the length of your crawl space and supports the entire floor framing system. When that beam rots or cracks, the whole floor drops. We remove the damaged beam, install temporary shoring, and replace it with an engineered beam sized for the load.
These problems start small. They don't stay small.
Floors that dip, bounce, or feel soft when you walk across them mean the supports underneath have weakened. The joists or beams holding up your floor are no longer doing their job.
Cracks above doors and windows are a sign the structure below is shifting. As crawl space supports settle or fail, the framing above moves with them — a sign you may also need foundation repair.
When floor framing drops even slightly, door and window frames go out of square. Doors drag. Windows jam. The problem is underneath — not in the frame itself.
A damp crawl space leads to wood rot, mold growth, and decay in the structural members holding up your home. That musty smell means the damage is already happening.
Our Process
We go under your house and inspect every beam, joist, pier, and support. We document everything with photos and measure moisture levels so you see exactly what we see.
You get a written report showing what's damaged, what caused it, and what needs to be fixed. We tell you what's urgent and what can wait. No pressure. Just a clear plan and a fair price.
Our crew installs steel support posts, sisters or replaces damaged joists, and repairs or replaces failing beams. Every post sits on a concrete footing. Every repair is built to last.
We walk you through the completed work and show you every repair. You get documentation of everything that was done and a warranty that backs it for the long haul.
We do structural crawl space work — not just encapsulation. Many companies install vapor barriers and dehumidifiers. That matters. But if your floors are sagging and your supports are failing, moisture control alone won't fix it. We repair the actual structure under your home. Jack posts, joist repair, beam replacement, foundation wall stabilization — the work that makes your floors solid again.
Every repair starts with a real inspection. Not a quick look through the access door. We go under the house with lights, cameras, and moisture meters. We document everything, show you the photos, and tell you exactly what needs attention. If something doesn't need repair, we say so. You get the truth — not a sales pitch.
We back our work with a warranty and stand behind every repair we make. You get a written scope of work before we start, clear communication throughout the job, and a final walkthrough when it's done. No surprises. No hidden costs. Just honest structural repair from a team that knows crawl spaces inside and out.

Every crawl space is different. Cost depends on how many supports need repair, how much joist or beam work is needed, and how accessible the crawl space is. That's why we start with a free inspection — so you get an accurate, itemized quote based on your actual situation. No guesswork.
Crawl space repair fixes structural damage — sagging beams, rotting joists, failing support piers. Encapsulation controls moisture with vapor barriers and dehumidifiers. They solve different problems. Many homes need both, but structural repair should come before encapsulation. Fixing moisture won't stop your floors from sagging if the supports underneath have already failed.
Most crawl space structural repairs take one to three days. Smaller jobs like a few support posts can be done in a single day. Larger jobs involving beam replacement, multiple joist repairs, and foundation wall work can take up to a week. We'll give you a clear timeline before the work starts.
Yes. Sagging floors are one of the most common reasons homeowners call for crawl space repair. We install adjustable steel jack posts on concrete footings to support the beams and joists under your floor. The posts can be adjusted to gradually bring floors back toward level without stressing the structure.
In most cases, no. Homeowner's insurance typically covers sudden damage — a tree falling on your house or a burst pipe — but not gradual structural deterioration from moisture, settling, or age. Some policies have exceptions, so check with your provider. We also offer flexible financing to make crawl space repair affordable with manageable monthly payments.
