Job Stories From Seneca, MO
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!
