Durable aluminum gutters, downspouts, & gutter guards in Andover

Creating a dry, secure property starts with having the best gutter system. If you have leaky gutters that easily clog or sag under heavy loads, then the water that spills over can ruin roofing, siding, landscaping, and even seep into the home or building through the foundation. That is why Thrasher Foundation Repair offers the Gutter Shutter system, guaranteed to never clog, sag, or pull away.

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.

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.
