"We were stuck in the middle of a plumbing project and couldnâ t complete it. We had been trying for hours to drill a hole into a stainless sink to no avail. We needed an expert! I googled plumbers in the area and found Felix right away. It was our lucky day because he was available and he came over immediately. What had taken us hours (without success) took Felix maybe 15 minutes tops. He came with the right tools as well as his personal experience and we were able to continue on with the installation of our reverse osmosis filter installation. Felix was fast, professional, reliable, and very friendly. Thank you Felix! You saved the day!!"

"Nathan and his crew recently did a partial remodel of our master bathroom. It is now a beautiful tub/shower. They did a wonderful job removing the old shower/tub, and drywall. Now there is a jacuzzi tub, travertine on the shower walls up to the ceiling, and new fixtures for the shower and sink. It looks like a museum piece. They also clean up thoroughly before they leave everyday, there are contractors that are not nearly as thorough as Nathan's team is. A great experience from start to finish, if you are in need of a remodel, don't hesitate to call Nathan"
