We used JMC to replace the deck in our backyard with interlocking. They came and in two days powered through the rain and completed our beautiful new backyard patio. It turned out better than we could have hoped - and it was the small things that made it better: raising the gate, trimming the window wells, etc. I'd definitely recommend JMC to anyone looking for interlocking, I'm hoping to use them again for some future jobs we have planned.
