What Our Clients Say
-
“Jason and his crew are far and away the best in the business. I have hired other companies to remodel parts of my house but Jason was the most attentive to my needs and also was willing to make suggestions that I hadn't even thought of. Jason's crew are punctual and professional craftsmen willing to go the extra mile to be sure I was satisfied with each phase of the project. The attitude and craftsmanship of Jason and his crew make JNM the best in the business. Thank you Jason, Brad, William and Josh for making our house more beautiful than we could ever have imagined.”

“Jason and his crew with JNM delivered outstanding work and attention to detail on our projects. After an extensive siding replacement project, we had total confidence in Jason and his team to take on a big interior remodel that included all new flooring, taking down walls, relocating a laundry room, bathroom revamps, bedroom carpet replacement, baseboards and trim, anchoring a deck, replacement and install of a slider, total kitchen gut job with new cabinets, island, butcher block and concrete countertops, hood range exhaust, backsplash tile, and each step of the process was smooth and there was extraordinary attention to detail.”

“I would give 10 stars if I could. When I called Jason about my countertops and house in general, he pointed me in the right direction for everything, replied back very fast, even came out to my home multiple times to help me figure everything out. He’s very caring and great at what he does. Not to mention you can’t beat his prices! I definitely won’t be going to anybody else after having the privilege to meet him.”
