Evan G.’s home was settling, and he was having trouble with doors shutting properly and cracking in the drywall. Looking for a long-term solution to stabilizing his home, his son recommended to have Thrasher come out and take a look.

We sent Service Technician, Matthew George out to the home. His was able to identify that the westers corner of his home was settling into the ground, which was causing problems inside the home. Cracks were also starting to appear in the floors and back patio. We were able to install Push Piers and attach them into the footings of the home to permanently stabilize the foundation and prevent further settlement.

Rori S. takes great pride in how her home looks. She has been dealing with ugly concrete slabs for a while. She had someone she knew attempt to repair them for her and they settled again. She didn't want to spend any more time and money on them and wanted something that will permanently fix the issue making her home look good and maintaining its value

The back patio gets a lot of water and she never wanted to deal with those issues again. We lifted and leveled the areas she was struggling with. On the driveway we put in CompressionGuard to prevent damage from street creep and sealed all cracks in joints to prevent water from saturating the soil.

Crawl Space Encapsulation in Sioux City, IA

These homeowners in Sioux City, IA noticed cold and hot air entering the inside of their home during each season. In the winter, cold air was seeping through the basement and floors above making it costly to heat the home. During the summer, hot and humid air was leaking into the basement making it an uncomfortable space to be in. All these negative effects are caused by a poorly insulated crawl space. The homeowners wanted to protect their home and knew over time it could lead to mold and rot. The customer called Thrasher and was impressed with our thorough inspection and detailed solution. They chose our solutions because they knew it was going to be the best permanent fix.

 System Design Specialist Corey Little and our team arrived at the Sioux City home and immediately began work on the crawl space encapsulation. Our team started by installing SilverGlo insulation to reflect and trap the heat in the crawl space. That was then paired with our CleanSpace waterproof liner to limit the amount of water vapor that can enter the space, and keep it dry to prevent mold and foul odors. These two products together provide a permanent solution for crawl space insulation.

 The customers were pleased with the efficiency, professionalism, and communication displayed by the team. In addition, they were impressed with the quality of work, and happy to have a peace of mind moving forward through the seasons.

Wall Repair in Hornick, IA

It’s understandable that no homeowner wants to deal with a failing basement wall. Unfortunately for those homeowners in the marker to sell their homes, neither do potential home buyers. This is the situation Dena S. in Hornick, Iowa was facing as she received low ball offer after low ball offer on her home due to stage 3 wall failure.


Dena had heard of Thrasher Foundation and trusted that we would do a good job, but also knowing that the work would come with a transferable warranty for the next homeowner was another reason why she chose to work with us. Once we had inspected the home and proposed our solution, Dena said they she couldn’t wait to get this job going so she could finally sell her house!


We fixed the problem by permanently stabilizing the 2 walls. On one wall we used our Everbrace wall support system due to it exhibiting extreme wall failure. On the second wall we used our Powerbrace wall support system to permanently halt the inward movement of the wall and possibly straighten over time if the new owner wishes to.


Once buyers found out she was getting the wall fixed with Thrasher, she got an offer right away and is closing right when the work is done.

Full Basement Waterproofing in Sioux City, IA

The customer was remodeling this home to sell to some people he knows. He wanted to make sure the basement would stay dry and that the water issues he experienced with the home doesn't cause future problems for them. Water would get into the basement when we got heavy rain. He would have to push the water over to the drain to get it out of the basement.

We used our WaterGaurd system all the way around the basement to ensure the whole thing would stay dry all the time. We put in full height clean space to limit the amount of water vapor getting into the home. We also used our triple safe pump to make sure they won't have to deal with the stress of a sump system failure. 

He enjoyed that our system would guarantee the basement space to be dry. He knows the quality work we put into homes and know we will make sure the new homeowners will have no problems. The new homeowners and he also liked that the 25-year warranty would transfer over to them.

We were able to meet with the current and future homeowners and they worked so well together to design a system that would fully take care of their needs. They were so happy that we can make sure the basement always stays dry and it won't be a problem for them. The future homeowner was worried the moisture would cause health concerns for their family.
