“If you are seeking an exceptional quality home, Vertical | Design+Build and Trade Mark Interiors is the team for you.”

“Grant Castilow and the entire team at Vertical Design + Build are simply the best. Grant took over a stalled project which we had begun with another contractor and immediately got it back on track and completed ahead of schedule and under budget. When does that happen? I would highly recommend him for any new construction or major remodel project.”

“Dear Anthony, Just want to thank you for helping me with the elevator pads – We appreciate your kindness and think you are pretty special.”
