"I had a 4 foot crack under a window well, 5 foot under another window well, and 7 foot total wall crack. All were actively leaking water into my basement - like fountains. Called Atlas and 2 other companies, and they responded first arranging Kaz to come out the next morning. I still hadn't heard from the other companies by the time he came. He evaluated the cracks, explained the injection procedure, quoted the price, and set up the appointment. The only negative thing was that the appointment was 3 weeks away and the cracks were significantly leaking. Because we had so much rain, I called again to try to get moved up, and they accommodated me on a Saturday for a $200 premium. Nestor fixed the cracks and the leaking stopped. He was polite, prompt, and answered all my questions. However, with the next rain, small wet areas were seen (nowhere near as bad as they were). I called back, appointment was made, and Nestor came back to fix them again under the lifetime warranty. Same great service with the call back, and no problems noted since! Would recommend, and also say that if you have small leaking, get it fixed, because you never know when it will get worse!"

"We were getting some water in our basement, which The Real Seal determined was coming from a crack in the foundation. They identified and repaired the crack quickly. Our technician worked neatly and efficiently, and all staff were pleasant and responsive throughout the process."

"The worker who came over saw my situation and unoffically suggested a repair that would be cheap for me rather than have him and his crew come out and charge me a few thousand. I appreciated that he wanted what was best for me and not necessarily best for his company."

"

I have an apartment building in which the garden unit had previously suffered water leakage.  I had the outside sealed previously, but wanted to get the inside sealed while the apartment was empty.  Chuck came out and offered three different solutions all with various price points.  We agreed to sealing just the inside for now, and if there were future leaks, we would consider the alternate solutions proposed.  In all 6 cracks were discovered.  Chuck had the cracks sealed and each of the tie bars sealed. 

I will be using them again for my other apartment units.

Foundation Repair questions, answered by experts

Periodic inspections and addressing drainage issues prevent further damage.

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.

Not all cracks in brick indicate foundation problems. For instance, small hairline cracks can occur as a new construction settles. However, larger cracks are often a sign of a more severe issue. Indicators of a potential foundation problem include long horizontal cracks, "stair-step" cracks, vertical cracks that appear indoors, or any crack that widens at the top. Other signs of structural damage to look for are uneven floors and doors or windows that stick. These issues could be caused by problems with the soil beneath the home or an overgrown tree.

Concrete can crack from general wear, improper installation, or in response to uneven support from the soil underneath. Small, thin cracks on the surface of aging concrete are usually a result of normal wear and tear, while cracks on new concrete more likely indicate a problem with installation. Larger cracks or uneven steps can signify a much more severe issue. A concrete contractor should be able to diagnose the cause and repair concrete cracks for you.

Yes, thicker concrete is less likely to crack. The thicker the concrete is, the less susceptible it is to extreme changes in weather conditions that often cause concrete to crack or chip. If you’re unable to install a thicker concrete driveway for any reason, you can also ask your professional to install more rebar or wire mesh to provide greater strength and better resilience to damage.
