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.

We are totally satisfied with the job you, Crannell Engineering, and In-House Plumbing did. It was a pleasure to work with you, although I hope we never have to again! Please also see our review in Angie's List.

I was apprehensive about such a large project on my home due to the cost and scope. Your team was great to work with through out the entire process. They worked quickly and professionally. The Project Managers were good at explaining the process. They did a decent job of clean up. Only complaint was broken plumbing a result of the lift, but that's to be expected I guess.

The crew did a great job and kept me informed and updated every step of the way. Everything was cleaned up and nicely restored when they were finished. While they were there, they even took the time to adjust some of the piers that A-1 had installed earlier this year.

Very good. Jeff was so helpful in explaining what was needed. And the crew did a fantastic job - quick and experienced. I don't know if you can say foundation repair is enjoyable, but I have to say that's how I felt when the crew was done.
