“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 115 homeowner reviews:

“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."
