"I highly recommend Alpha Foundations. The first guy they sent out to evaluate the problem, Joseph Green, was extremely thorough and professional. He went above and beyond to make me happy. The two men who did the job, which was leveling two patios and filling in a gap between the house and the patios and repairing two substantial cracks, Cooper and Blake, did an amazing job. They were extremely thorough, making sure they addressed all issues and they did the job in a timely manner and cleaned up as if they were never there. I am 100 percent satisfied with all three men and I would highly recommend them and hire them again."

"John Walters and the AAA Construction and Restoration team are highly recommended. Our townhouse was built in 1967 and the bathroom was in serious need of remodeling, including significant water damage to the living room ceiling. John and his staff accompanied us to Home Depot twice to assist in selecting materials. The construction team was professional, hard-working, and always aimed to please. In fact, realizing that being out of the home was difficult for our family, the team even worked on Thanksgiving. They also even came the day after Thanksgiving to ensure that everything was perfect. It was. Our new bathroom is beautiful, the ceiling repaired, other work was also done and we are extremely pleased with the results. John Walters and the AAA Construction Team are A++. Work done included: Full bathroom remodeling with new shower/bath, toilet, vanity, mirror, fixtures, floor and shower tile with border, light fixtures, vent, painting. Replacement of structural beams, living room ceiling patch-up Downstairs toilet replacement Front door frame replacement"

"They did a great job. They solved all the problems I had with the chimney and it’s been working perfectly ever since. They also fixed a problem on the roof around the chimney; they replaced the wood around the chimney with a material that would never rot, so they fixed it even better than it was before. It took them a couple of days to do the work. They took care of all the cleanup as well. We've been real happy with them."

"Once they started working on it, the work was great. What they did was good, but they forgot to put caulking on one of our skylights. They came back quickly to fix it. We put half the money down and then we didn’t hear anything for 4 months. I guess they were switching company owners, but since then it has been good."

Foundation Repair FAQs, answered by experts

If your foundation isn’t properly square, there’s a chance that anything you built before detecting the issue may need to be torn down. A major miscalculation could leave some walls of your home unsupported. 

It depends on the bank and the extent of the issue. Some banks will lend against homes with minor foundation damage, but most won’t if the issue is structural since the home acts as collateral for the mortgage. Banks that offer renovation loans might still finance a home with structural problems. More minor issues like settling cracks and intermittent problems with humidity are unlikely to stop a bank from financing.

Yes, you can fix a block foundation. It’s important to address the issue immediately and have a foundation repair professional understand the severity of the issue and determine the best course of action. If the wall collapses before the foundation is repaired, then you’ll have to reassess your entire foundation.

The actual foundation repair costs will depend on the extent of the damage, how many blocks you need, labor costs, and material costs. As an estimate, the average repair costs for a cinder block foundation fall between $350 and $25,000. Because the range is so large, it’s important to call a professional foundation repair company and have them assess the damage and estimate the repair costs.

Yes, sustainable mixes and sealants minimize environmental impact.
