"Kevin built us a custom storage shed, and we couldn’t be happier with how it turned out. It looks amazing—so much so that neighbors have actually stopped to compliment it! I’m pretty picky about details, and this definitely met my expectations. Kevin is honest, easy to work with, and clearly knows his stuff. There were a couple of small bump: his invoices were a bit hard to follow and getting him back to wrap up the final touches took a little extra effort, but in the end the shed is fantastic and I am very satisfied. I’d definitely recommend Kevin to anyone looking for quality custom work."

"We had a pretty big project, removing an old camp roof and building a new roof rotated 90 degrees, and adding a loft area. We were very happy with Andrew and his crew. They really go the extra mile to make sure everything is done right - they don't cut corners and take pride in their work. They installed new windows in the front and even used Windex to wipe off their finger smudges! Price was very good, and they're good, honest guys to work with. Very pleased!"
