"I hired Mark with Anderson Diagnostics on 2 separate occasions. Both were very positive experiences. The first time Mark changed out interior and exterior door hardware, and did drywall/wall texture repair. The second time I hired him to paint the interior of my home as well as change the baseboards in my master bedroom. He does excellent quality work and communicates very well. I also feel like he has integrity. I plan to hire him for future jobs."

"Really responsive and prompt, especially in the installation phase. We did have a couple of small hiccups, which in my mind a homeowner should expected on literally any remodeling project, and they were resolved quickly. Communication on final details like inspections could have been smoother, but overall the whole process was very clear, well managed, and well executed. Happy with the choice to go with Red Rocks."
