Durable aluminum gutters, downspouts, & gutter guards in South Sioux City

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.

Robert B. is a proud homeowner in South Sioux City, NE and considering moving within the next year. Before entering his home on the market, he wants to have complete confidence his house is in the best condition to achieve its highest value. However, the north wall of his basement foundation was showing visible signs of failure. Robert was familiar with Thrasher and our dedication to a quality solution and customer service. System Design Specialist Joe Mulheim arrived at Robert’s home and performed a thorough inspection on the failing wall. It was determined that it was experiencing stage two wall failure and was visible from both the outside and inside of the home.

 To begin repairing the foundation wall, our team used five of our GeoLock Anchor systems to permanently stabilize the wall and return it to its original position over time. The team opted to use this product because there were obstructions in the home’s joists that would have been costly to move. These anchors are embedded deep into stable soil and then attached to the steel plates on the interior of the wall (pictured in the after photo). GeoLock Anchors are installed year-round and often completed in less than one day.

 Robert was thankful for the painless solution we were able to provide, and for restoring the value of his home. He was impressed with the entire process and now has confidence his home will bring maximum value on the market.

Estel T. in South Sioux City, NE was looking to do some maintenance on his home. For a while now he been having problems with water leaking in his basement. Not wanting to deal with the cleanup and mess anymore, he decided it was time to investigate waterproofing solutions. After hearing about Thrasher’s reputation, he gave us a call.

System Design Jon Young went out to Estel’s home. He was able to identify that there was no waterproofing system in place. The crew installed WaterGuard, an interior basement drainage system. Also, to keep the walls dry, they encapsulated the areas with CleanSpace, so water would no longer come through. From start to finish Estel thought the process went smoothly and was happy not to have to worry about the water anymore.
