Homeowner Reviews

“Complete Basement Systems installed a window well sump pump for us. Although the weather was not cooperating, they went ahead and installed the pump as intended, and the electrical was installed about a week later. Overall, a top-quality and professional job!”

“Did a great job of lifting a settled concrete patio to prevent water draining into foundation.”

“Great job sealing my crawl space to remove critters.”

“With flooding in the basement, we felt like we were in crisis. Complete Basement Systems came in, developed a workable plan, and were affordable. We were glad we selected them as our contractor.”
