Services

Foundation repair services across St. Louis

Structural repairs, waterproofing and concrete work for houses in the city, St. Louis County and St. Charles County. Every one of them starts with the same free inspection.

Pick the problem, or let the inspection pick it

Homeowners often call about one thing and learn it is another: a wet corner that turns out to be a settling footing, a crack that turns out to be harmless. You do not need to know which service you need before you call.

Foundation Crack Repair

Before anything is injected, we answer one question: is this crack a sign of movement, or just the concrete shrinking as it cured? The answer decides whether you need a sealed crack, a structural repair or nothing at all..

Structural, water, or both

Settlement, bowing walls and cracks are structural: the house or a wall has moved. Leaks, damp crawl spaces and failing sump pumps are about water. In St. Louis clay the two are often linked, because water is what makes the soil swell and shrink. The plan covers both where they are connected.

Structural repairs are done under a permit from the city or county office for your address. Plumbing connections, where a job needs one, are made by a licensed plumber.

Seeing a crack you did not see last year?

Call or send the form. An inspector measures the house, explains what is moving and why, and puts the repair and its price on paper before anything is dug.
