“I spent a number of years as a field engineer on large commercial projects. My strength is knowing construction....I like giving personal service. You are not hiring a big company. You don’t see a service truck come out to do the work. You hire me, my knowledge, and my experience.” - Charlie Flagg, President

Select Quotes from Customer Reviews

A selection from 164 homeowner reviews:

“They were wonderful. They were absolutely marvelous. They solved my problems, and I’d had two or three other people work on the basement who didn’t solve the problems, but I haven’t had a drop of water since Flagg came. I was impressed with that. He knew exactly how to fix the problem—he had several drains to fix and ditches to dig, and they were perfect.”

“They are best in the whole wide world. So, on a scale of one through ten, they get a twenty. They were the most professional workers—they were fabulous.”

“They did an excellent job. I had a water leak in about two or three locations, and they basically came in and sealed those, and the work’s been holding up quite well. They cleaned up after themselves and did everything just as they promised.”

“It was a wonderful job....Charlie was extremely knowledgeable, took the time to explain everything that he was doing and why, and made sure that it was a premium job for me.”

“Every time it would rain really hard, water would come in our entry and in the garage. We never knew why, and we never could fix it, and then we found Charlie Flagg. He’s the only one who was able to fix this. Very, very good. He’s magic.”

“He gets a total thumbs up all the way around for us. He really listened to all of our concerns...really cared about addressing everything; he wasn’t just about a quick fix just for the obvious issue. He provided an outlet for that water to move out of our house, whereas before it was getting trapped. He created a scenario where the water could exit freely. We just really appreciated it....He acted as a consultant as well as a repair person.”

“He took care of our basement at the other house, and then we had him come look at our new house before we moved in. He showed us where we could potentially have problems. After we moved in, we realized that there were drainage problems around the house, and he came over and fixed all of that. He’s excellent.”

“He was fabulous. He not only looked at the problem but found the most sensible way to fix the problem. He kept me informed all along. I would always recommend him. Charlie looked at the problem to see how to solve it, rather than just spend money on it. That made sense to me.”

“He does good work. He’s done those waterproofing evaluations as well as actual waterproofing work where he’s filled cracks with injections. I would give him a very positive rating.”

"He’s superb.  I had puddles of water when I bought my house, and I’ve had zero since the work was done.  He sealed some cracks in my foundation.  I’m extremely confident in him.  Everything has lasted.  We just got a big flood, and my basement’s dry as a bone.  They’re that good."
