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.

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.

There aren’t enough words to explain how to express my satisfaction with A1. My family and I have been in this house for 13 years and the floors have never felt this secure. The diligence of the entire team made this successful. The team leads kept me informed of every step, ensuring I was aware of all work. The entire crew were extremely friendly, and also explained the tasks they were working on when asked. I am 100% satisfied and would recommend A1 to all.

It was great! I had worried about this process for years before I bit the bullet and decided to have it done. I was not disappointed. Mario was so great in explaining every step in the process, and took pictures for me to see. He was very reassuring and I really appreciated his attentiveness. Overall, the process was surprisingly simple. The crews were very efficient - we couldn't believe they finished in 8 hours! They did a great job cleaning up too!

The crew was fabulous. I was very satisfied with their work. I have not been able to finish the plumbing inspection because I need to have a clean out going to the house installed before the sewer test can be done. I have contacted a plumber to do the job. He just hasn't scheduled it yet because of the rain. Steve at In-House Plumbing Company asked me to call him when the clean out has been installed and he will come back and finish the inspection.

Company represenative (Kevin) was extremely helpful and accommodating. He was the main reason that we chose A1-G. Work crew was also very efficient and helpful. Third-party structural engineer was congenial and qualified but late to promises on reports/data.
