Foundation & Basement FAQ

Mostly water and soil movement: clay soils that shrink and swell, poor gutter and grading drainage, and settling of fill or river-deposit soils. Tree roots and plumbing leaks can add to it.

Usually not when the cause is settling or soil movement. Some policies cover sudden events like a burst pipe. Check your policy and ask your insurer.

For major movement, or a home sale or purchase, an independent engineer's report is a good idea and gives you an unbiased scope to compare contractor bids against.

Generally yes. Horizontal cracks in a basement wall usually mean soil pressure pushing the wall inward, a structural issue. Vertical hairline cracks are often shrinkage.

When it's wider than about 1/4 inch, horizontal, stair-stepped, leaking, or growing. Mark the ends with a pencil and date to track it.

DIY sealants can slow seepage in hairline cracks, but they don't fix structural movement. Have anything beyond a hairline crack inspected.

Saturated soil creates hydrostatic pressure that forces water through cracks, the wall-floor joint and porous block. Overflowing gutters and downspouts emptying near the foundation make it worse.

Exterior membranes stop water at the wall but require excavation and cost more. Interior drain-and-sump systems relieve pressure and are more common for existing homes. A contractor should explain why one fits your house.

Many local contractors offer transferable warranties, but terms vary. Get the warranty in writing before signing.

For damp crawl spaces, encapsulation plus a dehumidifier can control humidity, mold and wood rot. Ask for a moisture reading before and after.

Moisture-damaged joists, undersized beams, too few supports, or settling piers. Supplemental steel support jacks are a common fix.

Most homes take one to three days, depending on size and whether drainage or structural work is needed.

Often yes. Wall braces, anchors and carbon fiber install from inside or with minimal digging. Walls bowed past about 2 inches may need excavation.

Carbon fiber is low-profile for walls with minor bowing. Steel braces handle more movement and some can be tightened over time to straighten walls.

Active bowing can progress to collapse. Have it inspected promptly, and keep water away from that side of the house.

Push piers are hydraulically driven against the home's weight to a refusal depth. Helical piers have screw plates and are torqued in, which suits lighter loads or new construction.

It depends on the length of the settling section and the home's weight. Contractors typically space piers every 5 to 8 feet.

Sometimes partially. Contractors usually aim to stabilize first and lift only as far as is safe for finishes and plumbing.

Polyjacking uses smaller holes, weighs less (so it adds little load to weak soil), and cures in minutes. Mudjacking is often cheaper. Both work in the right situation.

It can last many years if the underlying drainage problem is fixed as well.

Often yes, if it's still in one piece. Badly broken slabs may need replacement.

Often 7 to 10 years, depending on use. Test it each spring by pouring water into the pit.

If your basement is finished or you've had water before, yes. Storms knock out power exactly when the pump is needed.

Well away from the foundation (typically 10+ feet) and not onto a neighbor's property. Check local rules.

Gutters, downspouts and grading. Simple fixes sometimes solve the problem before costly waterproofing is needed.

A gravel-filled trench with a perforated pipe that collects groundwater and carries it away from the house.

A common guideline is about 6 inches of fall over the first 10 feet. Check local code.
