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

“The design and quality that Grant Castilow and his team put in to the homes they build is unparalleled.”

“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.”
