Most of what we fix in Chattanooga starts with moisture or movement — a wet crawl space, water after a hard rain, or clay shifting under the foundation. Here’s what we do about each.
Diagonal cracks from your windows, doors that stick, a floor that slopes to one corner — that’s the foundation settling on our clay soil. We drive steel piers down to stable ground to stop the movement, then lift the settled section back toward level. The work is done through small access points, not by tearing the house apart.

Not every crack is structural — a thin vertical one is usually just shrinkage. The ones that matter run diagonally from doors and windows, step through brick, or are wider at one end. We seal those with polyurethane or epoxy that flexes with the wall so they don’t reopen, and if the crack is really a settlement problem, we fix the movement first.

Soft, bouncy, or sloping floors usually trace back to the crawl space, where moisture has rotted the joists and let the support posts sink into the clay. We jack the floor back up, set new adjustable steel posts on concrete footings, and sister or replace any rotted joists. We fix the moisture at the same time so the rot doesn’t come back.

Most Chattanooga homes have a vented crawl space that stays damp, and that moisture rots the floor and pushes musty air up into the house. We seal the floor and walls with a heavy vapor barrier, close off the vents, and add a dehumidifier to keep it dry. It stops the rot, clears the smell, and eases your summer cooling bill.

When water shows up after a hard rain, sealing the inside of the wall won’t stop it — the water just finds the next gap. We install an interior drain below the floor that catches the water as it comes in and routes it to a sump pump. The right setup depends on where the water’s getting in, which is what the free inspection is for.

The sump pump is your last line of defense against water under the house. We install a primary pump sized to the water you actually get, with a battery backup so it keeps running when the power drops in a storm — which is exactly when you need it.

Most of what we fix in Chattanooga traces back to the clay, the water, and the humidity. Here’s what that does to your home — and why people call us to deal with it.

The soil here is clay, not sand. It swells when it rains and shrinks in a dry spell, and that constant push-pull works on your footings until something cracks. On the ridges and slopes around the valley, soil leans sideways against foundation and retaining walls, and over the limestone underneath, voids can open and drop a section of the house. We build the fix around what the ground is actually doing — not just the crack you can see.
Most homes here sit over a vented crawl space, and the climate keeps it damp — humid air most of the year and more than fifty inches of rain. That moisture rots the joists and beams holding your floors up and pushes musty air into the house. Drying the crawl space out and keeping it that way is the fix that protects the structure above it.
We tell you what you need and what you don’t. Not every crack is a structural job, and not every damp crawl space needs full encapsulation — when that’s the case, we say so, even when it’s the smaller ticket. You get the cause, the options, and the cost in writing, with no pressure and no scare pitch.

If you’re noticing a musty smell, soft floors, water, or cracks, you’ve probably got questions. Here are the ones we hear most.
It comes down to the clay and the water. Our soil swells when it’s wet and shrinks when it dries, and that movement cracks walls and settles foundations over time. Add a humid climate that keeps crawl spaces damp and hillside lots where soil pushes sideways against the walls, and you’ve got the three things we get called for most.
A thin vertical crack is usually just shrinkage from when the concrete cured — not structural. Watch for diagonal cracks running from the corners of doors and windows, stair-step cracks in brick, and any crack that’s wider at one end than the other. Those point to movement, especially if your doors are sticking or your floors are sloping. When in doubt, the inspection is free and we’ll tell you straight.
A vented crawl space pulls in humid air, and the clay underneath holds water instead of draining it, so the wood never gets a chance to dry. Over time that dampness rots the joists, grows mold, and pushes a musty smell up into the house. Sealing the space and controlling the humidity is what stops it.
Usually not. Insurance treats foundation settling, crawl space moisture, and rot as maintenance, not sudden damage — and that’s most of what we fix. It may cover a sudden event like a burst pipe. Check your policy, but plan on paying out of pocket. We offer financing to make it manageable.
It depends on what’s wrong. A single crack repair runs a few hundred dollars. Moderate work — crawl space supports, drainage, encapsulation — runs into the low thousands. Major structural work with piers or wall stabilization goes higher from there. We don’t quote a number sight unseen; the inspection is free and you get the exact cost in writing before any work starts, with financing available.
It gets worse and it costs more. A damp crawl space keeps rotting joists every season. A settling crack widens as the clay swells and shrinks. A moisture problem that’s a sealing job today can turn into replacing joists and girders if it sits long enough. The fix rarely gets cheaper by waiting.
