"Called company on Monday and got an appointment for an inspection on Wednesday. That following Monday, the technician arrived and went through each step is sealing off the concrete foundation to the water leak. The fix worked well and was put to the test with the recent record rains. Not one drop of water came into the basement."

"I just bought a house in Glenview. I was looking for a company that could install a drainage solution to one side of my house. The grade runs towards the north side of the house causing excess water runoff and potential seepage into the basement. I did my research and found ULB-DRY Waterproofing. I have to say that the entire process was absolutely flawless. Their estimator came out to assess the situation and provide solutions. They had to come out a second time to perform a site survey to make sure their solution would work properly (making sure there was enough pitch from the front of the property to the back to drain the water). Once everything was assessed we scheduled a day for their crew to come out to perform the work (installing a french drain to move excess water build up away from the side of the house). They also connected one of my gutter downspouts to the pipe to drain that water away also. The crew was very professional, hard working, and technically sound. Not many companies have all these attributes. They really knew what they were doing. This company is awesome."

"All of the floor joists in my family room were rotted and/or collapsing due to prolonged water damage. Atlas staff, including the salesman Jim and engineer reviewed the situation and recommended a waterproof membrane and pitching the sidewalk on one side of the building away from the building. When water tested this only provided a partial fix of the problem. We eventually decided on drain tile and adding a concrete sidewall around the entire perimeter. This appears to have been the addition step needed. Only time will tell. There is a 10 warranty against water seepage. Robert and his team were great to work with. They were timely and responsive to my questions and concerns. The project took a little longer than expected due to having to add the drain tile and additional walk way."

"Out of the three basement waterproofing experts we called to offer solutions after getting a lot of water in the basement of our 1925 home, Joe at The Real Seal was the only one who seemed to take serious time in investigating the cause. He even came back a second time after we got more water in another spot to see what could be causing it and what a cost-effective solution might be. On top of that, the price was right! We never ever felt pressured into committing to the work, and they seemed confident in their skills to get the job done. Our partial interior drain tile job was finished in two days. While we can't yet vouch for the drain tile's efficacy since we haven't gotten a large spring rain yet and we're still in the process of refinishing our basement after it was demoed for this work, we expect we'll have a dry basement!"

"I had been having water leakage problems into my lower level family room for quite some time. Real Seal correctly diagnosed the problem, quoted a reasonable price, showed up to perform the work per agreed upon date and fixed it permanently. Even with the wet spring this year, I have not had any further water leakage problem. I highly recommend this company"

"I was getting water seepage in my basement last year. I called many of the well known waterproofing companies for an estimate and recommendations. They all wanted to tear up my basement and were very costly. I then contacted Allegro and spoke to the owner (Boris) Boris came to my house and did an extensive inspection and made a recommendation. He did all the work on the outside of my house causing the least disruption and mess. His price was very reasonable compared to the other waterproofing companies. He showed me that he really knew his knowledge of waterproofing. It is now almost a year after the work was preformed and my basement is dry. I waited until now to rate this company to see if his work held up. I'm glad to say after recent heavy rains, my basement is dry. Thanks Boris!"

Basement Waterproofing FAQs, answered by experts

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. The chances of mold developing depend on several factors, including the severity of the damage and how quickly the area is cleaned and dried. To prevent mold, you must act quickly—ideally within the first 24 hours. Clean up all water and thoroughly dry the affected area. If the damage is extensive, you were unable to address it immediately, or you suspect mold has already started to grow, it is best to assume it is present and hire a professional mold inspector or removal expert to assess the situation.

Some basement waterproofing methods can actually cause your water or moisture problems to get worse, which is why it’s so important to call in a professional who knows how to solve your underlying issue and use the appropriate waterproofing methods. An example of this would be applying latex waterproofing paint to the insides of your basement walls without fixing the water issue outside. Doing so can trap moisture in the basement walls, which can promote mold growth, peeling paint, and even damaged concrete. However, when done by a professional, the only downside to basement waterproofing is the up-front cost.

Roughing in and connecting utilities are the hardest parts of finishing a basement, and they’re the parts we typically don’t recommend doing as a DIY project. Unfortunately, your finishing timeline can be extended by weeks while you wait for contractors and inspectors to install electrical wiring, plumbing lines, and heating/cooling equipment and carry out inspections.

Preventing future basement flooding often involves installing sump pumps, improving drainage, sealing foundation cracks, and maintaining gutters. Costs vary, but preventive measures can range from a few hundred to several thousand dollars, depending on the solutions chosen. Investing in prevention can save you money on future flooded basement cleanup costs and repairs.

A plastic vapor barrier should completely cover your basement to prevent water from penetrating through the walls. This typically goes before installing insulation to prevent moisture from building up and becoming trapped on the inside of your insulation, where it can collect and lead to mold damage. Installing insulation after the vapor barrier allows for any moisture to exit the walls for better ventilation.
