Straight answers, no runaround.
Your driveway and garage floor are separate concrete slabs, built with a flexible expansion joint between them so they can move independently without cracking each other. Over time that joint filler dries out, shrinks, or washes away, leaving an open gap. Resealing it is a quick, inexpensive fix compared to what happens if it's left open.
In the Houston area, the most common cause is expansive clay soil underneath the slab swelling and shrinking with rainfall and drought cycles, not poor original construction. Nearby trees can make it worse by pulling moisture unevenly from the soil.
An open crack or joint is a direct path to the soil underneath, which is exactly what water, weeds, and insects are looking for. Sealing it closes that entry point and also slows the erosion that leads to bigger settlement problems.
It's common and usually not structurally serious — exterior slabs sit on unengineered soil and can settle unevenly over time. It's typically fixable with polyurethane foam leveling rather than a full replacement.
No. Foundation repair addresses your home's structural foundation. We handle exterior flatwork — driveways, walkways, patios, pool decks, and garage floor slabs — which sits on soil rather than being part of the home's structural system. If we see something that looks like an actual foundation issue, we'll tell you honestly and point you toward a foundation specialist.
They're different materials requiring different sealer chemistry. Concrete uses a penetrating sealer and flexible joint sealants; asphalt uses a coal-tar or asphalt-emulsion blacktop sealcoat. The two aren't interchangeable, and using the wrong one won't bond or perform correctly. Most Houston-area driveways are concrete, and that's what we specialize in.
Yes — ask about specific warranty terms for your job when you call. Texas doesn't license concrete repair contractors specifically, so a strong warranty and documented work history are how we stand behind the job.
