About
I'll take each job seriously. No job too small. When I joined US Army I fixed helicopters. Attention to details is a must because lives of people depend on quality work. I carried this attitude to civilian life.

I was impressed. He literally rose my grill from the dead and gave it new life. Outstanding level of detail and mechanical knowledge on how grills work. He cleaned every inch of the grill, making it show-room, out-of-the-box quality. I recommend his services 150 percent!

Val did a great job installing three Container Store Elfa reach in closets as well as building a bookshelf and anchoring it to the wall. He spent all day working hard, came to us when there were any issues with the supplies, and cut shelving that was incorrectly sized. He fit us in easily and came prepared with a van full of equipment to make sure the job could be done. Super nice guy!
