Basement Waterproofing
Chicago’s wet climate demands professional basement waterproofing. Our interior drain tile systems, crack repair, and moisture control solutions permanently eliminate water intrusion, protecting your home and creating dry, usable living space.
Foundation Repair
Foundation problems are common in Chicago due to expansive clay soils and freeze-thaw cycles. Our foundation repair solutions—including crack injection, wall bracing, and pier underpinning—restore structural integrity and prevent further damage.
Concrete Leveling
Sunken driveways, patios, and sidewalks are safety hazards common throughout Chicago. Our polyurethane foam injection technology lifts and levels concrete in hours—not days—at a fraction of replacement cost.
Window Wells
Properly installed window wells prevent water intrusion while providing emergency egress and natural light. We install, repair, and replace window wells with drainage systems designed for Chicago’s heavy rainfall.

Every Chicago basement needs a reliable sump pump system. We install primary pumps, battery backups, and water-powered emergency systems to keep your basement dry during Chicago’s notorious spring storms and power outages.

Chicago’s humidity makes crawl space encapsulation essential. Our vapor barrier systems, dehumidifiers, and drainage solutions eliminate moisture, prevent mold growth, and improve your home’s air quality and energy efficiency.

"Hired this company to install 3 window well drains last year in August. The drains have been effective, even through all the heavy rains this year. The price was fair, and the crew was professional. We are happy with the results. I definitely plan on considering this company again in the future for concrete lifting.
