"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

Foundation repair can affect home value positively or negatively. If you address the underlying issue and hire a foundation repair contractor to complete the work—especially one that includes a warranty for the work—then your repair will likely increase your home’s value. If you fail to pull proper permits and cannot prove that a licensed expert completed the work, there’s a chance buyers will view your home in a negative light and end up offering less for your property.

Although some concrete cracks are cosmetic, others can be more serious. Cracks wider than ⅛ inch or that extend through the slab are serious and can cause structural damage. If you notice these types of cracks in your concrete patio, contact a local contractor who installs concrete patios to inspect the damage and determine how to fix it.

Cement companies offer a wide variety of services, including delivering and pouring concrete for home foundations, walkways, patios, driveways, concrete steps, pools, pool decks, and more, plus concrete repair and patching. Most companies also have the ability to demolish and haul away old concrete landscaping features. It’s a good idea to reach out to a few different companies before hiring to make sure you choose one that can tackle the entirety of the project you have from start to finish. This method will typically save you some money over hiring multiple contractors.

Underpinning is a specific type of foundation repair where a specialist installs deep piers under a foundation to provide additional support. This method is often used when the soil beneath the foundation can no longer evenly support the structure. Foundation repair is an umbrella term that includes many methods. Besides underpinning, other common repairs include foundation crack repair, waterproofing, cosmetic repairs, and concrete block wall stabilization. Often, underpinning is accompanied by other work to address the root cause of the foundation issue, such as regrading the yard to ensure water drains away from the house.

Yes. Foundation walls are always load-bearing.
