A Madison-based foundation repair and basement waterproofing crew. We work on Dane County's clay soils, the isthmus high water table, the Glacial Drumlin cut-fill subdivisions, and the Norwegian-heritage masonry of downtown Stoughton. 30+ years of combined Wisconsin foundation experience, no franchise overhead, no out-of-state corporate office sending the inspection report through a sales pipeline.
Foundation crack repair via polyurethane and epoxy injection. Basement waterproofing through interior drain-tile systems, exterior dimple-board membranes, and sump-pump installation. Bowing-wall stabilization with carbon-fiber straps, helical wall anchors, and steel I-beam bracing. Foundation settlement repair using helical piers and push piers. Egress window installation for code-compliant basement bedrooms. Sump pump replacement with battery-backup options sized for Dane County water tables.
Foundation contractors who refuse to publish ranges almost always charge more than the ones who do. A homeowner walking into an inspection with no reference point will accept whatever number sits on the first quote. Our pricing pages exist so the inspection conversation starts with the math already on the table: $400 to $800 per crack injection, $70 to $110 per linear foot for interior drain tile, $1,500 to $2,500 per helical pier. The job-by-job number lands inside those ranges based on soil profile, access, and engineering scope, and the quote breaks out every line item.
We will not run a high-pressure sales pitch. We will not quote a project before we have walked the basement. We will not recommend a repair the engineering does not support, even if the homeowner asks for it (we have walked away from carbon-fiber jobs that needed wall anchors, and from wall-anchor jobs that needed wall replacement). We do not subcontract the structural work. We do not paint a crack and call it repaired.
All of Dane County plus the western edges of Jefferson and Rock counties. Madison core out through Verona, Middleton, Sun Prairie, Fitchburg, Waunakee, Stoughton, McFarland, Monona, and Cottage Grove. Each city has its own soil profile and its own predictable failure patterns, mapped on the individual service-area pages.
Fully insured general contractor. Wisconsin does not require a state foundation-repair license, but we carry general liability above industry minimums and pull permits on every structural job through the Dane County building inspector's office. We will email a current Certificate of Insurance on request before the truck rolls. Ask the dispatcher.
