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! 

Basement Waterproofing in Andover, KS

In Andover, KS, this homeowner dealt with basement water issues and poor experiences with contractors for years. After discovering Thrasher and our extensive reputation, they gave us a call to provide her a permanent solution and restore her peace of mind.

Thrasher arrived at the home in Andover, KS, and immediately went to work installing our basement waterproofing products. The customer chose to have us install our WaterGuard interior basement drainage system and TripleSafe sump pump to replace the old one. These two products work together to keep the basement dry year-round.

Concrete Leveling in Andover, KS

This homeowner in Andover, KS was frustrated with his concrete’s appearance and potential of becoming a tripping hazard. Over time, the concrete leading up to the front door had settled causing it to sink and even crack in the deepest areas. They had a couple estimates from different companies, but the customer quickly realized none of them have a reputation quite like Thrasher.

 To begin the project, System Design Specialist Brent Randolph inspected the front entryway and discussed possible solutions with the homeowner. He opted to have our PolyLevel and NexusPro solutions installed for a permanent fix. PolyLevel is fast-acting and strong high-density foam that levels and lifts the concrete from its sunken state, permanently. Our team then paired that with the NexusPro sealant to seal all cracks and joints to prevent moisture from entering in the foreseeable future.

 The homeowner was more than satisfied with the final appearance and the professionalism our team displayed. After completing the project, he said he’d highly recommend Thrasher to anybody for all concrete needs.

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.

 In order to solve these issues, Robert designed a gutter shutter system fit for a house that size and buried the downspouts to drain the water effectively. The gutter shutter greatly improved the capacity of water flow preventing any overflow during heavier rains. This new system prevents any bottlenecks throughout the drainage process.

 The customer was more than pleased with the new gutter systems appearance and functionality. She now has confidence that her basement will stay dry, and her house is protected from any rain that comes her way.

Andover, KS Driveway Repaired to Prevent Settling

Carrie S.’s driveway formed a bump due to settling concrete. Each time Carrie would pull into the driveway she would have to drive over the bump and growing tired of it, she decided to give us a call.

We sent System Design Specialist Austin Ure out to Carrie’s home and he was able to come up with a solution that didn’t require Carrie to have to replace any of the concrete. We stabilized and lifted the concrete flush to the garage with PolyLevel and NexusPro. Carrie was impressed with the solution we came up with because it didn’t require new concrete.
