"Gavin Gordon exhibits excellent customer service and professionalism. After requesting an appointment online and choosing a day/time, the appointment was confirmed and scheduled. After asking us about our concerns, Gavin inspected the home inside and out, measured, evaluated the levels and gave us his expert recommendations. The experience was very informative and we are confident that our foundation issues will be repaired and resolved by Alpha Foundations."

"The owner of the company was in contact with me as the work was being done at the property. Pictures of the problems were sent as the project moved forward. Pictures of the repairs were sent during each phase of the cleanup and repairs. Couldn't ask for better communication. All repairs were done by the company employees of ADVANCED ENVIRONMENTAL SERVICES. No waiting for subcontractors for days or weeks on end. I received quotes from 4 different companies, and their quote was the most reasonable. When the project was completed I was pleased with the professional work with a guarantee they would come back free of charge if any mold reappeared. Professional, easy to contact, and most knowledgeable company I ever worked with,"

Foundation Repair FAQs, answered by experts

The best solution to fix a foundation crack in your basement floor depends on the underlying cause. If you just have hairline cracks from settlements that are no longer growing, the best option is to seal them with a crack sealant. If the cracks continue to grow, one edge rises above the other, or there are signs that water is getting in through the crack, a professional repair will be necessary. Depending on the root cause, your professional may employ foundation underpinning or some other type of stabilization, seal the cracks, or install a drainage system.

Most single-story homes don't have foundations strong enough to support a second story, but they can be reinforced for an addition. A structural engineer can assess your foundation and what needs to be done to get it ready. They'll look at any cracks or unevenness in your current foundation and consider any special framing or beams your home needs, especially if it’s in a high-wind or hurricane area.

“To support a second story, many structural engineers will require that you install additional concrete piers in the crawlspace,” says Tschudi. “This involves hand excavating, pouring a large concrete footing—usually with specially coated rebar—and then building concrete piers right up to the girders.”

The best way to determine if ceiling cracks are structural is to hire a ceiling contractor to inspect the cracks and provide a professional opinion. That said, you might be able to make an educated guess based on the size and appearance of the crack. Larger cracks, cracks accompanied by sagging or discoloration, and cracks that travel from the ceiling down the walls are all signs of structural issues.

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.

Foundation cracks that are 1/8 inch wide or less, aren’t uneven across the gap, and don’t continue widening over time are usually just normal settling cracks and don’t suggest structural issues. Horizontal cracks and stair-step cracks on foundation walls, any cracks that continue widening, are wider than 1/8 inch, or where one side juts out beyond the other, are often indicative of structural damage.
