We have a crawl space and have been concerned about the dirt floor for sometime. It also had a musty smell at times. To me it was just a dark place I didn t want to go into. Our furnace is located down there. It is so much brighter now with the white covering on the floor and walls. We were very pleased with Eric and Justin and the work they did. They were very polite, professional, and helpful.

Still not real happy with initial install. If it was just about Tony these questions would all get a 10!

Job Stories From Spencer, IA
Patio Repair in Spencer, IA

These homeowners were planning on selling the house down the road as they are both older and wanted to make sure they get the full value out of their home. The patio has been a pain for them for years and they wanted to make sure they get this fixed and protect the rest of their concrete. They wanted quality work done and wanted to ensure they would have a good warranty and company that stands behind their work. They knew of Thrasher and our reputation, so they gave us a call. System Design Specialist, Corey Little, came out to meet with them. Corey found the patio was starting to crack and bust apart. This was due to wash out and dry out of the soil underneath between the rainfall throughout the years and this years recent drought. He came back to the homeowners with these findings to talk through the best solution. Together, they decided on using Polylevel to lift the areas that needed to be lifted. Then we used it to stabilize the rest of the patio to ensure that it no longer settles and cracks. We used NexusPro to fill in the cracks and joints to prevent water from washout anymore. We also used this on the rest of the joints in the non-sinking areas, to prevent it from happening there. They were very pleased with the work we did, and were excited there was no need to replace when it was possible to just fix! We know they now have the peace of mind they need for resale, and for the future homeowners down the road.
