FOUNDATION REPAIR DALLAS: The A1 Guaranteed Foundation Repair Process


Once we have completed a thorough assessment of your home and determine foundation repair is necessary, we’ll provide you with a detailed report and discussion on what is needed and help you understand what the process will entail. We then schedule a date to complete the work.


Upon agreement, an appointment is made with an Independent Engineering firm to certify the repair plan.


With our approved plan, We install the piers in the approved locations to maximum depths. We work around bushes and plants as best we can, and if we have to remove them we do our best to preserve and replant them.


Our skilled foundation repair teams will very carefully and thoroughly employ techniques to level your home’s foundation based on your plan.


Once leveling is complete, we completely clean up the work area, we take any extra dirt and fill in any low areas on the property and then perform minor mortar repair to the exterior of the home.


Appointments are made for a final report from the engineering firm and a plumbing test is performed.

Request a Foundation Repair Assessment/Estimate by filling out the Get Your Free Estimate form on the right.

FOUNDATION REPAIR: What Causes Foundations and Slabs to Sink?

With more than 20 years of foundation repair experience, we have found that the majority of foundation problems are rooted in one of the three areas mentioned above.


Moisture changes in North Texas cause drastic clay composition changes. Acting like a sponge, soli expands during seasons of heavy rainfall and contracting during times of seasonal drought. Continuous fluctuation causes stress on your home’s foundation. Commonly, the center areas of the slab remain undisrupted, while the perimeters settle due to exposure to the seasonal moisture changes.


Trees and large shrubs with the extensive root systems require immense amounts of moisture to sustain their health. Moist soils located near the edge of the home, as well as underneath the slab, provide a viable source of water. And when the root system drains the additional moisture from these areas, it causes the slab to settle.


More common these days, plumbing has become a major issue for foundations. The cast iron plumbing commonly used in the 1960s and early 1970s is beginning to deteriorate and erode. The soli directly underneath the home can infuse with water, creating long-term foundation damage.

The service was very organized and handled professionally. Mr. Steve Greenhill is great in answering every concern that I had. Ms. Mariana at the office is prompt in replying my phone calls and messages. The working crew showed up on time and very organized. All these helped to make the whole ordeal less stressful. Thank you.

A friend/co-worker recommended A1 to us, because she was pleased with their work, so we hired them to do 12 piers, inside and outside our home. They definitely put the customer first!! I was very impressed with their organization and hard work! They sent 14 workers, each knowing exactly what their job was and the supervisors managed the entire operation efficiency and with professionalism. Awesome Job completed in ONE DAY!! I would definitely use them again

A1 did what they said they were going to do. They arrived when promised, did the work fast, and left my home the same condition as when they arrived -- despite Ll the holes. Good workers!
