Trevor DeimelLocal Guide · 51 reviewsTotal number of Google reviews Trevor has written across all businesses on Google Maps, not just this one.
Review from Google · view on GoogleHad Calculus put in both Helical piers for the foundation of our addition that had sunk as well as install a French drain system in our basement as it was consistently leaking. Basement has been bone dry since the waterproofing has been done and the helical piers crew went above and beyond with pulling out a tree including the stump and repairing our fence even after they said they weren’t going to do that. Neighbors complemented how well they cleaned up the crew site as well.
Response from the owner · a week ago
Thank you so much! We’re really glad to hear your basement has stayed completely dry and that the helical pier work helped get your addition back on solid footing. It also means a lot to hear how our crew went above and beyond with the tree, fence, and cleanup. Hearing that even the neighbors noticed the care they put into the job is a wonderful compliment. We truly appreciate you trusting Calculus Foundation Repair & Waterproofing with your home!
