Foundation Repair questions, answered by experts

A sinking foundation can be lifted, most often by installing piers to re-level and support the weight of the house. Depending on the cause and extent of the sinking, other methods to lift a foundation include underpinning and mudjacking. Consult a foundation repair pro to determine the best way to lift your sinking foundation. 

Yes, foundation repairs are worth it if you have a significant problem or see signs that could worsen if not dealt with. If your foundation fails, your home can lose up to 20% of its value. Protecting your home from serious structural damage and avoiding more costly repairs later is well worth the money.

Depending on the severity, a slab leak can go undetected for months or even years, especially if you don’t carry out routine foundation inspections to find foundation leaks early. However, minor leaks are likely to turn into more severe leaks over time, so you might notice increases in water bills and issues with yard drainage, even if the problem is minor.

If your foundation repair claim gets denied, the first step is to carefully read over your policy and denial letter so you understand the reason for the denial. Then, gather evidence and documents that can support your case and appeal the denial with your insurance company. If your insurer does not eventually honor your claim, you may want to file a complaint with the insurance department in your state. In some cases, it may make sense to work with an attorney and file a lawsuit.

Crawl space foundation problems can stem from a few different issues, but the most common are moisture and water problems and soil instability. Moisture and water issues are often a result of poor drainage, which can lead to water intrusion and soil expansion and contraction, leaving your foundation under added stress. A few things can cause soil instability, including poor drainage, karst landscapes and resulting sinkholes, and poorly compacted soil during construction.
