"The estimator (Kaz) was prompt, informative, and responsive to my many queries before I signed a contract. The project manager and workers were all very prompt, professional, and courteous. They were respectful of our property and that of our neighbors, taking off their shoes when inside and cleaning up their work. I asked them to run an additional line from one of my downspouts, which was done without incident. We also worked together to problem solve an issue related to the sump discharge line. On day 1, they cut our buried cable line because it was marked incorrectly. However, the foreman called the company and it was resolved/fixed within a few hours (it has taken more than a day in the past when I’ve called!). I was quite surprised at how they cleaned up after excavating for the 6 inch drainage pipes. They estimated 5 days to complete the work and finished in 3 days. While I was not excited to spend that much to fix the problem, we knew we needed to address the improper drainage. Additionally, while I feel that I know what needed to be done and probably could have done so myself for less money, it would have taken me 3 months, not 3 days with my schedule. Overall, I’ve been pleased with the work and may have them come back and address an additional drainage issue in our yard in the future."

"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."

"Fantastic guys! Came out right away to fix three cracks in my foundation. Looking forward to using them for an epoxy floor in my basement. I would refer them without hesitation."

"For initial contact, Jason came on time, spent an hour trying to diagnose problem.  It was difficult because walls in crawl space are covered with spray foam.  He submitted a preliminary proposal.  I requested another meeting to discuss options and review  the proposal.  Jason readily agreed.
In our next meeting Jason did additional investigation, finding a gap in the wall that could not be seen from inside because of the spray foam, and identified another potential source of leakage.  Submitted proposal to patch the gap, and in the other area to remove spray foam as required to locate the source of leakage, patch the crack(s), and reinstall the spray foam.   Proposal was accepted and the work performed on time, and of good quality.
Unfortunately, a heavy rain revealed that we had not found all leak sources.  The crew came back in reasonable time, patched another gap in foundation, and removed spray foam in a second area to find an additional crack which had not been patched correctly by the previous owner.  This crack was patched correctly and spray foam reinstalled.  After the next rainfall, there has been no evidence of further leakage.
There was no additional charge for the second repair session, as it was covered by warranty.
I am very satisfied with the quality of the work, the promptness of scheduling, and the followup communication.

Foundation Repair questions, answered by experts

You have different options depending on the scale of repair needed. If you are repairing minor cracks that are between ¼ inch to 1.5 inch wide and less than half an inch deep, a self-leveling polyurethane sealant would be your best choice. Polyurethane sealants dry to the touch within one to two hours. Since they come in a tube applier, you also have the option to complete the repair without emptying out your garage.

If your foundation isn’t properly square, there’s a chance that anything you built before detecting the issue may need to be torn down. A major miscalculation could leave some walls of your home unsupported. 

Yes, foundation repairs are worth it if you have a significant problem or see signs that could worsen if not dealt with. If your foundation fails, your home can lose up to 20% of its value. Protecting your home from serious structural damage and avoiding more costly repairs later is well worth the money.

Foundation repair uses methods such as underpinning, slab jacking, or application of hydraulic piers. Each technique is chosen based on structural needs, soil conditions, and damage extent, ensuring a stable and secure foundation.

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.
