"I was getting water in my basement every time it rained, Dan helped me rule out other causes and recommended a french drain. Basement has been bone dry ever since. The workers took great care and even repaired the water damage from before. I highly recommend calling Basement Gurus for any basement related needs"

"They worked steadily, efficiently. They were respectful of our other furnishings trying to keep the dust and dirt from getting to them. They were pleasant to speak with. They explained a few things when I asked. I would recommend them to anyone that was looking for a company that would deal with their water in the basement problem."

"The job inside was done. However the drainage put in outside has turned our yard into a swimming pool. We once had a pipe draining to the creek and this was a perfect solution to the rains/weather. These guys came in and put a round small cylinder well. Water pumps up into our yard turning it into a swamp. Called them to come and see the problem they created. Their response $2900 to fix THEIR DAMAGE. I WOULD NEVER RECCOMEND THIS COMPANY!!"

"We hired Groundworks (formerly Baker?s Waterproofing) for a $20,000 basement waterproofing project that was promised to be fast, dust-free, and high-quality. Instead, our home was left coated in concrete dust, parts of the job were rushed, and unsafe wiring still powers our sump pump. Promised electrician service has yet to happen. Three months later, the $10,000 filtration system is still unusable. This project has cost us significant time, caused stress for our family, and left us with ongoing safety concerns. We cannot recommend this company based on our experience. Although one middle manager tried to help and arranged partial repairs, upper management ignored most issues. Three months later, the air filtration system remains unusable, electrical hazards persist, and no restitution has been made. What an exhausting mistake at a deeply personal cost. "
