"We purchased a beach house that had an open French drain and 2 sump pumps in the basement. We spoke with several contractors, none of whom diagnosed why the pumps were running continuously and why the sisterns were always bubbling up water onto the front lawn. ACM diagnosed the problem, explained to us what was wrong. They were the only people we spoke to who really understood what the issue was. They recommended several upgrades, installed the new basement floor and sump pumps. This fixed the issue. They completed the work on time and on budget. HIGHLY RECOMMNEDED "

Foundation Repair questions, answered by experts

The best foundation repair method will depend on the issue you’re having, but usually, foundation instability is best fixed using supportive piers, like steel piers or helical piers. A professional foundation repair contractor or structural engineer should always decide what the best course of action is, and even then, it’s imperative that you also take measures to treat the underlying issue as well, like soil erosion or oversaturation from runoff.

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. 

Cracks, shifting, or uneven floors indicate potential foundation issues.

You can use a level or straight-edge to test for plumb foundation walls and a level slab, a level or a ball to check for sloping floors inside your home, and a hygrometer to look for moisture in your underhome area. Aside from these DIY tests, it’s important to get a foundation repair specialist or structural engineer to test the foundation to see if it’s supporting your structure properly. They can determine if the loads on the concrete are uneven or need reinforcement.

If improperly installed, an egress window can compromise your foundation’s structural integrity, so it’s important to work with a pro to ensure your foundation remains in good shape. Any money you may save on a DIY egress window installation may cost you in the long run if your foundation is damaged in the process.
