That following Monday, the technician arrived and went through each step is sealing off the concrete foundation to the water leak. The fix worked well and was put to the test with the recent record rains. Not one drop of water came into the basement."

"The worker who came over saw my situation and unoffically suggested a repair that would be cheap for me rather than have him and his crew come out and charge me a few thousand. I appreciated that he wanted what was best for me and not necessarily best for his company."

Foundation Repair questions, answered by experts

In most cases, yes, homeowners insurance will cover burst pipes, even if they run through your foundation. Not only that, but most home insurance companies will also cover any foundation repair you need done that resulted from the plumbing leak because your insurer will view the leak as an unforeseen and non-preventable issue.

Yes, slab leaks are fairly common, especially in older homes and places that are prone to earthquakes which can move home foundations.

Overwatering can cause issues like water pooling and drainage problems. To prevent overwatering, monitor your soil levels on a regular basis and change your watering schedule as necessary.

Most houses are expected to settle over time, but foundation sinking of more than a few inches or uneven sinking of more than an inch for every 20 feet is cause for concern. Any significant or uneven sinking should be assessed by a professional to determine the cause and perform any necessary repairs. 

A leak under your foundation from a water supply line or sewage line is likely to lead to water pooling on certain areas of your property during rainfall, abnormally fast-growing or green grass in certain sections of your lawn, and differential settlement of your foundation, which can result in large foundation cracks, windows and doors failing to operate properly, a wavy or sloping roofline, or damages or irregularities in your interior walls, including cracks and bulging. If it’s a plumbing line embedded in your slab, you’ll also likely notice above-average water bills.
