Carrie S. hated that her driveway had created a nasty bump due to settling concrete. She had to drive her car each time over the bump and was looking for a driveway repair solution that didn’t require replacing the whole driveway or have mismatching pieces of concrete. She saw a Thrasher advertisement and decided to give us a call.

System Design Specialist Austin Ure went out to the home to see what we could do to fix the problem.

Charity H. is a homeowner in Andover, KS and was fed up with water seeping into her basement every time it rained. She became concerned with the damage water could cause on the foundation of her home. Needing a permanent and quality solution, she gave Thrasher a call.

 System Design Specialist Robert Griffin arrived at the scene to perform and inspection on the home. After investigating the exterior of the house, it was obvious the size and quality of the gutters were the issue. They weren’t large enough to handle the capacity of water needed to prevent them from overflowing and washing out the soil against the foundation. In addition, the downspouts hadn’t been maintained and were also contributing to the erosion of soil every time it rained. To combat this issue, Robert designed a gutter shutter system specifically for this home and buried the downspouts to drain the water effectively. In addition, our team added wide mouth outlets to the downspout for increased flow and prevention of any bottlenecks in the system.

 Charity was thrilled with her new gutter system’s appearance and functionality. She was impressed with our variety of solutions and dedication to her well-being. She now has confidence that her basement will stay dry every time rain is on the forecast.

Homeowner Ken P. in Andover, KS noticed the concrete leading to his front entryway and back patio had settled over time. The concrete had sunk and began to crack in the deepest areas. Frustrated with the appearance and worried about it becoming a tripping hazard, Ken decided it was time to get it fixed. After receiving bids from other companies, he quickly realized none of them had a reputation quite like Thrasher.

 To begin the project, System Design Specialist Brent Randolph arrived in Andover, KS to fully inspect the concrete areas that were problematic. The customer opted to have the team install our PolyLevel and NexusPro solutions. PolyLevel is a lightweight and strong high-density foam that lifts and levels the concrete permanently. It’s an effective solution because it not only lifts the concrete, but also compacts the soil underneath to ensure the concrete remains stable. Then, the NexusPro is applied to seal all the cracks and joints. It’s a durable solution that prevents moisture from entering long into the future.

Ken was grateful for our quality of work, display of professionalism, and dedication to doing the job right the first time. Ken loves the way his concrete looks and now has confidence in its functionality.

Stephanie S. is a homeowner in Andover, KS, and was becoming increasingly more frustrated with the water issues in her basement. She had contacted multiple companies for solutions, but none of them were effective or solved the problem. After viewing our reputation and process, she was confident that Thrasher would provide the permanent solution her home needed.

To begin the waterproofing project, our System Design Specialist Brad Painchaud arrived at the home in Andover and performed a full inspection. After discussing possible solutions, Stephanie opted to have Thrasher install our WaterGuard basement drainage system and TripleSafe sump pump to replace the old one. WaterGuard is an interior installation and doesn’t require any excavation of the outside soil. It’s designed to capture the water at the cold joints in the foundation of the home and carry it to the sump pump to be released outside.

Stephanie was thrilled with our waterproofing solutions and to finally have the confidence she needed in her home. After the first few rainstorms and no water issues in the basement, she was thankful that she could rely on Thrasher for a permanent solution.

Job Stories From Andover, KS
Concrete Protection in Andover, KS

This homeowner has had concrete work done before, but decided he wanted to be proactive and protect the rest of his driveway. He gave Thrasher a call because he knew he could trust us to give him the best results. System Design Specialist, Carl Ness, came out to meet with him. Carl surveyed the area, and came back to the homeowner with the results. His concrete driveway by his garage had settled back down in a few areas and the caulking had come unbonded. The cause being shrinking and expanding of the soil beneath the drive, along with not enough poly being used when lifting and leveling. Together, they decided the best solution would be use our Concrete Protection System. Polylevel would be used to lift, level, and stabilize the concrete back in place, as well as using NexusPro to seal the joints and cracks. The homeowner loved this solution, so we sent out our installation team. The homeowner was very happy with the results, and there is no doubt they have the peace of mind they were looking for!

Gutter Replacement in Andover, KS

This Andover, KS homeowner was tired of water seeping into her basement and concerned with the damage it may cause to her foundation. She made the call to Thrasher, and we had one of our System Design Specialist, Robert Griffin, head out to the property to perform an inspection. After examining the gutter system in place, it was clear they weren’t large enough to handle the capacity of water needed. In addition, the downspouts had not been maintained properly and were washing away the soil against the house.
