"I wish all the contractors on this basement project were as good to deal with as Family Waterproofing. Throughout the whole process, communication was good. Ken the owner was responsive and patient in answering all my questions and addressing concerns. They prepared a detailed contract of all work to be performed, and did what they said they would. I like that they did an exploratory dig after signing the contract to make sure we had a solid plan and avoid any surprises during installation. There was an area under the basement stairs and an old cistern that required a creative solution. They came up with a solid plan that didn't add extra cost. I asked them to pour some extra concrete under the stairs which wasn't included in the contract, which they did for a good price. The crew was friendly and had a good natured camaraderie on the job. The overall cost was very fair and we received great service and quality. They are honest, care about their customers and want you to be happy. Now I'm looking forward to a big rain!"

"The bathroom remodel was in April 2018. The job was finished one day later than described and that was unavoidable because I live in a very old house. Larry and Augie were absolute gentlemen, talented and skillful, and the job was cleaned up every day before they left. They arrived on time, took their lunches and breaks nearly to the minute and kept me informed every day of what was happening. The family room remodel will be completed next week when the bar top is installed and this job went exactly the same as the bathroom. Tommy and Eddie were also complete gentlemen and also very skillful and creative because in this old home creativity was a necessity to overcome some obstacles. Andy, the project manager, continually made his presence known and I felt very comfortable contacting him for any thoughts or questions I had. I would most definitely use Apex again."

"If I could give them zero or negative stars that would be more to the quality of the work they did for me. I contracted them to install 13 windows in a brand new patio door on my mobile home. Dan and his partner were the installers and initially I thought it was just some lack of attention to detail and poor quality in their workmanship but it turned out it was completely just negligent ********! Almost every window leaked cold air when it came time in the winter and after they had finished installing everything towards the end of November beginning of December. Missing caulk lines and having the use my own insulation and drywall because of the negligent job they did. They had to come in and recaulk around almost every window and or put insulation in but I ended up doing most of that myself. The worst was the opening they left on each corner of my patio door and a few other windows and with all the rain and snow I ended up with black mold and fungus growing inside at the base of the door"

"We had quotes from 30,000 to 60,000. It was like some of these guys wanted to rebuild the house. Kenny Wood initially came in close but under the lowest, but still a little too much for our budget. We discussed it and he made some suggestions to save money but still get the job done. His guys came in the next week, got right to work and did an excellent job. I would definitely hire Kirkenlow again."
