Concrete Crack & Floor Repair in Janesville, WI

Concrete crack & floor repair is often the biggest part of a coating job in Janesville. A slab that has taken decades of road salt, or one poured thin under a detached garage, can be cracked, pitted and scaled. A coating will copy every flaw underneath it, and loose concrete will take the coating with it when it lets go. Concrete crack & floor repair gives the new floor a sound base.

Why so many slabs need work here

Janesville's housing spans a long time. Census survey data for 2019 to 2023, compiled by Point2Homes, shows about 14% of the city's homes were built in 1939 or earlier and the median year built is 1972. Concrete that age has been through decades of winters. The city averages about 36.6 inches of snow, and the 2008 Michigan Tech review for the South Dakota DOT found that sodium chloride usually causes severe scaling when concrete freezes and thaws. Scaling, pop-outs and cracked joints are common on garage floors near the door.

Types of damage we repair

• Hairline and shrinkage cracks: opened up and filled so they do not telegraph through the coating
• Wider cracks: routed and filled with a rigid or semi-rigid filler, depending on movement
• Spalling and scaling: loose surface removed and rebuilt with a repair mortar
• Pitting and pop-outs: filled and ground flat
• Chipped control joints: edges rebuilt, then filled or left open as you prefer
• Low spots: built up where water collects

When a crack is more than cosmetic

Some cracks point to bigger problems. A crack that keeps getting wider, one where one side sits higher than the other, or a slab that heaves in winter and settles in summer can signal soil, drainage or foundation issues. HomeAdvisor notes that foundation repair for structural cracks costs $2,150 to $7,730 or more. That is a different trade. If we see signs of it, we tell you before you pay for a coating.

Resurfacing a worn slab

When most of the floor is scaled, spot repair is not enough. A resurfacing layer over the ground slab gives a new, even surface to coat. HomeGuide puts concrete resurfacing at $3 to $7 per square foot, and HomeAdvisor lists typical resurfacing projects at $1,000 to $5,000. We tell you whether spot repair or resurfacing fits your slab and price it in the written quote.

Repair as part of coating

Most of the time, repair is done in the same project as the coating. After diamond grinding, we can see the real condition of the concrete, fill and patch it, grind the repairs flush, and roll the base coat that day or the next. Doing it together keeps the cost down and gives a continuous finish.

Repair without a coating

If you only want cracks filled or a few areas rebuilt, we can do that too. Bare repairs are more visible than repairs under a coating, and we explain how they will look before we start.
