"Blake was punctual and professional as he evaluated the crack in my concrete driveway. He was pleasant and explained why this was not the ideal match between Alpha and the repair I needed. Given the quality of Customer Service, I was disappointed to not be able to hire Alpha."

"I used to get water in my basement every time it rained. I had a sump pump installed and I still got water through the cracks. Seal pro Max was the perfect solution for me for fraction of the cost of other solutions. With all the snow and rain we’ve had this year I didn’t get a drop of water in my basement. The guys were very knowledgeable and professional and were able to finish the job in one day. I wish I knew about this years ago."

"Overall I am totally satisfied with the job done by Danilo Leyva. He is a trustworthy, very capable person who I would recommend 100 %. My only suggestion is to make sure you discuss with the crew that is forming the job, the drainage aspect of the area being poured. There they slipped up a little bit. But overall I am extremely happy with the worked one."

Foundation Repair FAQs, answered by experts

The average cost to repair a concrete driveway ranges from approximately $830 to $2,800, with a typical project costing around $1,765. The price varies widely depending on the type and extent of the damage. Minor crack repairs can be as low as $0.10 to $0.15 per linear foot and may be a DIY project. More significant repairs are priced per square foot: replacing a damaged slab costs about $6 to $14, while raising or leveling sunken concrete costs $3 to $25. Resurfacing is another option, costing around $3 to $5 per square foot. Factors influencing the total price include the size of the affected area, whether reinforcement is needed, and labor costs.

Yes, foundation problems can cause ceilings to collapse or even your whole house to crumble. Left unaddressed, natural sinking can build up and eventually harm your home’s supporting structure, such as walls, beams, and frames. Your basement ceiling may be the first place to look for signs of a ceiling collapse caused by foundation problems.

While a contractor is on-site repairing your concrete steps, you can have them inspect other concrete surfaces for minor damage. They may be able to fix cracks in your driveway or garage floor during the same visit. You can also ask them to check your home's foundation for minor issues they can address. However, general concrete repair experts typically cannot handle larger jobs, like leveling a sunken foundation. For major structural projects, you will need to hire a structural engineer.

If your concrete steps have crumbled or chipped, you can fix them by removing any chips or flakes, cleaning and wetting the affected area, applying a concrete bonding agent, and finally applying new concrete, usually in the form of Portland cement. For widespread damage, you can consider concrete resurfacing instead. For fixing concrete spalling that has led to deep damage, you might need to remove damaged material, add structural supports, and pour new concrete into a mold.

Whether you need a permit for foundation repair depends on your location and the scope of the work. Major repairs like foundation stabilization typically require a building permit, while smaller projects such as sealing non-structural cracks or applying waterproofing solutions often do not. It's crucial that your contractor follows all local building codes, as an inspector will review the work to ensure it's up to standard. Failing to obtain the necessary permits can create issues when selling your home and may lead to further damage if the work is not done correctly. Your foundation repair specialist will usually know if a permit is needed and can handle the process for you. You can also contact your local building department or municipal office to confirm the requirements and verify that your contractor has filed the appropriate paperwork.
