"Atlas did a fantastic job. Mike accurately diagnosed the problem (a foundation crack hiding behind wood paneling) and patiently explained it to us new homeowners. For the repair itself, he arrived on time, applied epoxy efficiently, and dealt with some unexpected obstacles. (Some flooring needed to be removed to -literally - get to the bottom of the issue.) Our neighbor highly recommended Atlas, and we see why!"

"Quacker's Waterproofing was wonderful. When they came for the estimate, they were fast and no nonsense. They weren't trying to convince me of things that needed doing or dramatizing the work for more money. When I had questions about the work, they didn't make me feel dumb but took extra time out of their day so that I had peace of mind with my foundation. I hope to never need their help again, but I will definitely call them if I do. Special kudos to Rob!"

I don't recall the date this occurred, but it was not July 2015, but the format requires a date.  In any event, I was concerned about a foundation problem, and Roberts sent a representative out who inspected inside and outside and advised that while he would love to have found a problem that would have involved an expensive repair, he could not do so because he saw no foundation problem.  He was as honest as the day is long, extraordinarily polite and gave considerable supporting statements as to his determination.  I really appreciated his integrity.

"I was very fortunate to have High & Dry to tackle couple of cracks that used to leak water whenever it rains. These cracks repaired couple years ago. So far I had No water leaking whatsoever. Job well done. Company you depend on. Fast, clean, reasonable. I’m a customer for life. I normally don’t write a bunch of reviews generally speaking. I had to leave thumbs up for their work. A BBB rating and been in business for over a decade."

"Finish Touch gets 5 stars from me. They built us a beautiful looking retaining wall at the rear of our house 4 years ago this month and were the low bidder by far--the bids ranged from over $17,000 to under $3000 for Finishing Touch with several others from 6k to 10k. I waited to post a review until now because build quality of a retaining wall can't be measured until after passage of time. Their wall has held up nearly perfectly over 4 years now so I believe it is justifiable to say it was properly built and the preparatory pre-construction work like ensuring drainage was all done well. On top of doing first rate work at the low price, a few months ago I contacted Mr. Watson about another potential job involving our crumbling and sagging concrete front steps and porch. He spent a good 20 minutes+ explaining we could get 90% of the benefit of redoing them by instead mud jacking them and using polymeric sand to fill a crack. He was right. I unreservedly recommend them."

Foundation Repair questions, answered by experts

In O'Fallon, homes with finished basements, walk-out lower levels, or mature landscaping often present access challenges for foundation repair. Split-level designs, additions, or attached garages can further complicate repairs. If your home has multiple foundation types or visible prior repairs, expect more involved planning. Watch for utility lines or irrigation systems near the work area, as these can also impact repair strategies.

Helpful?

To make foundation repair in O'Fallon safer for your family, clearly mark work zones with temporary fencing and communicate boundaries to everyone at home. Create indoor safe spaces away from noise and dust, and try scheduling repairs during school hours. Relocate pets if heavy equipment will be used. Keep windows closed near the work area, run air purifiers, and lock away all tools and materials when not in use.

Helpful?

In O'Fallon, schedule foundation repair if you notice widening foundation cracks, doors or windows that stick, uneven floors, or water seeping into your basement after storms. Seasonal changes, such as soil shifting after heavy rain or drought, can also signal problems. Regularly inspect your home’s foundation and act quickly if you see signs of soil movement or structural settling to prevent further damage.

Helpful?

O'Fallon’s humid summers, cold winters, and expansive clay soil can influence foundation repair timelines and methods. Spring rains may saturate the ground, causing delays, while summer heat can affect curing times for materials. Winter freezes often halt repairs. Local tornado and flood risks mean it’s wise to monitor forecasts and plan for possible weather-related interruptions when scheduling your project.

Helpful?

When comparing quotes for foundation repair in O'Fallon, be cautious of unusually low estimates, vague repair plans, or high-pressure sales tactics. Trustworthy professionals provide detailed written proposals, explain their methods, and reference local soil conditions. Avoid contractors who skip site visits, won’t discuss cleanup or warranties, or refuse to provide local references. A thorough soil analysis and clear communication are key indicators of reliability.
