These homeowners were struggling with severe sagging floors which were causing problems when they were renovating their home. When they decided to have something done about this, they gave us a call and we sent System Design Specialist Justice Haven. Justice inspected the homeowner's crawlspace as sagging floors are commonly a result of crawlspace problems, and he found that the crawlspace had a lot of water which had weakened support structures. He determined that this was due to the soil in the dirt crawlspace washing out and leaving moisture to cause problems with the structure. After discussing these problems with the homeowner, Justice designed a solution in which the crawlspace would be encapsulated and kept dry, as well as new support would be added to combat the sagging floors problem. One of our installation teams came out to this home and installed SmartJacks and supplemental support beams to reinforce and stabilize the flooring, then, they installed CleanSpace Vapor Barrier to encapsulate the crawlspace and keep it dry. The homeowners were very happy with the outcome and they were excited to have their renovation continue. Check out the newly supported crawlspace!

Foundation Repair in Seneca, MO

This homeowner wanted to restore her childhood home she had inherited from her parents. This meant a lot to her, and wanted quality work done. She was aware of Thrashers reputation, and was confident we would do a great job for her. She also loved how we stand behind our work. System Design Specialist, Trevor Stokes, came out to meet with them. Trevor found the East and South walls were tipping in and there were leaking cracks on the walls. She wanted to add a bedroom, living room, and bathroom in the basement. These issues needed to be resolved before proceeding with these plans. The homeowner was impressed at our thoroughness and willingness to take the time to explain everything, and we sent out our installation team. We used PowerBraces to stabilize the leaning wall, and WaterGuard with CleanSpace to help drain the water into the Sump Pump. The homeowner loved this solution. There is no doubt this homeowner has the peace of mind of her childhood home and is able to finish the basement without worries!
