"Very professional and fixed the cracks in the garage the best that I can tell. Expensive fix but well worth going with the carbon fiber, you get a 15 year transferable warranty with it. Only deducted half star because they didn't show up on a modified scheduled date."

"Vincent Police, the owner, started and completed the work as per the schedule. He was on site the majority of the time both supervising his crew and performing the work. He kept me informed on a daily basis and was very helpful explaining the scope of work as it took place for removing the slab in my 2 car garage and pouring a new reinforced slab. The finished product has a professional looking appearance and the crew left a totally cleaned site. I'm very satisfied with the work and i recommend AA Outdoor Services for similar projects.d"

Foundation Repair FAQs, answered by experts

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, engineers assess soil load-bearing capacity and provide construction guidelines.

Yes, slab leaks are fairly common, especially in older homes and places that are prone to earthquakes which can move home foundations.

Many horizontal cracks in home foundations result from water and soil pressure from outside of the building or from a footing that is shifting. Under those circumstances, horizontal cracks are a structural problem that requires repair before they become worse and more difficult to fix. However, in very specific cases, thin horizontal cracks may simply be a cosmetic blemish due to concrete shrinkage.

If improperly installed, an egress window can compromise your foundation’s structural integrity, so it’s important to work with a pro to ensure your foundation remains in good shape. Any money you may save on a DIY egress window installation may cost you in the long run if your foundation is damaged in the process.
