"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

Water can seep into porous materials like wood beams, floor joists, and roof rafters within minutes, but they’ll need to see prolonged exposure before you have structural damage. Mold can start growing within 24 hours, and mold can eat away at the structural components over time. Wood rot is more of a concern, though. Wet and dry rot are fungal infections that set in in moist conditions and rapidly deteriorate wood, causing major structural damage within just a few months in some cases.

If not properly maintained, an underground downspout may damage your home's foundation. A clogged downspout can back up, causing water to pool around the base of your home and seep into the foundation. Regular inspections and maintenance keep your downspout in good working order, preventing damage and protecting your home.

Yes, it is possible to over-dehumidify a house by removing too much moisture from the air. This can create an overly dry environment that negatively affects those with respiratory or skin issues, and may cause your skin, hair, and sinuses to feel dry. However, this is unlikely to happen with most modern dehumidifiers, as they are equipped with moisture sensors and adjustable settings. These features allow the unit to pause automatically when the desired humidity level is reached, preventing the air from becoming uncomfortably dry. In contrast, older or more basic dehumidifiers left running for too long could potentially over-dry the air. To avoid this, aim for a balance between removing excess moisture and maintaining a comfortable environment. You can often monitor your home's humidity levels using a modern thermostat for guidance.

Yes, barndominiums can have basements. Barndominiums are typically built over concrete slabs, so barndo basements are not very common. However, it is possible to include a basement in a barndominium blueprint as long as you’re building completely from scratch. Barndos can have the same types of basements as traditional homes, including full or walk-out basements.

Most houses will have vents in the crawl space. This allows for air passage and energy retention, which in many ways can help control the temperature inside the home. If you are able to consider the cost of a crawl space encapsulation, you may not need your crawl space vents at all.
