"The crew was absolutely amazing! Very impressed with how professional, polite, and personable they all were. The management and crews are top notch! Management answered all the questions I had, walked me through what steps they were going to take to get things done. Dustin was extremely thorough, knowledgable, and took time to explain the recommended systems. I will 100% be utilizing them in the future strictly based on the level of trust and quality he presented! His communication was fantastic, they always arrived on time. They were careful with the property, always cleaned up when they were done. I will absolutely hire them again to complete any future foundation/basement work and I will absolutely recommend this company without reservation or hesitation. They stand behind their work."

"We did a lot of research prior to hiring Thrasher and we were not disappointed. Frankly I had been in denial (and fear) about the work I knew we needed done on our Midtown Omaha home because I was so concerned about the cost and impact on our brick Tudor. We had a crack in the brick near our garage and our basement had been leaking for a number of years with hard rains. From the start of the process, Thrasher was outstanding in terms of communication and education about what they do. Before we met with our Systems Design Specialist, Anthony, we had received e-mails and calls to confirm the date, along with a packet of educational materials about home foundations and waterproofing. When Anthony came to our home, he was very professional and performed a full inspection about our concerns. He prepared an estimate and we selected what was best for us following a thorough review of options he presented. The foundation work was completed first in ONE day. The basement waterproofing was completed the next week over a two-day time frame. The workers were very professional and arrived at the time they arranged with us. In regard to the basement waterproofing, we discovered one small issue. They came out immediately to correct this and all has been worked wonderfully since. We are very pleased with their work and commitment to customer service. Highly recommend Thrasher to anyone considering foundation or waterproofing work."

"Excellent service. Courteous and did a good job covering everything with plastic and cleaning up. They answered all of my questions and were always on time. They worked every day and did it in the time they said they would (one week). They came back after the ground dried to bury and sump pump line outside. The true test was all the rain we had this spring and my basement stayed dry!

Basement Waterproofing FAQs, answered by experts

Proper drainage is the only way to ensure that your crawl space stays dry. Depending on your property and the extent of your issue, you might need to consider a gutter system, a French drain, or sump pumps to avoid and handle water and moisture under your home. Dehumidifiers can also help to prevent moisture from accumulating if you have a high-humidity environment.

Water leakage through window openings is much more common in older homes, but it can also create issues with window frames that are improperly installed. If left unattended, water buildup can cause damage to surrounding fixtures, lead to harmful mold, and compromise the architectural integrity of your home. The potential damage that a water leak poses makes investing in weather- and water-proofing your window frames entirely worthwhile.

While water in your basement is unlikely to make you sick unless it’s coming from a sewage backup, mold is likely to start to grow in wet areas within 24 hours, and mold can make you sick. According to the Centers for Disease Control and Prevention (CDC), inhaling mold spores can cause allergy symptoms, including runny nose, itchy eyes, difficulty breathing, wheezing, and itchy skin. Individuals with pre-existing respiratory issues like asthma and immunocompromised individuals are at an elevated risk of symptoms when inhaling mold spores.

Rigid foam board insulation is one of the safest insulation materials for basement walls. The panels offer a moisture barrier to prevent mold and mildew build-up. At the same time, this material is also fire-resistant, so you don’t have to worry as much about a fire breaking out as you would with spray foam insulation. 

While it’s possible to seal a foundation yourself, it’s not recommended, as it’s a tricky and labor-intensive job. Foundation sealing is best left to the pros to save yourself time, remove the risk of doing it wrong, and keeping yourself safe. Call a foundation repair professional near you to see what the job will cost.
