"VERY impressed with the work and overall professionalism of Coast to Coast. From the proposal/quote stage all the way through payment, everything was fully communicated, executed quickly, and delivered with the utmost attention to detail —probably 2-3 weeks from first contact to finished work. They fixed the tuck pointing on our very old, crumbling limestone foundation and installed 3 glass brick windows. Even rough areas I would've expected them to miss because I hadn't explicitly pointed them out were touched up. Would definitely use again in the future. THANKS"

"Set up was done nice and clean."

"Car key programming by Tom's Car Locksmith was fast, accurate, and professionally handled. The technician quickly synced the new key, tested everything thoroughly, and ensured smooth, reliable vehicle access without delays."

"Tom was on time and did the needed work. I highly recommend him and would definitely use him again."

"I would highly recommend MG Doors and Mark. He is a true expert and is also an extremely kind person. We shopped around to three different vendors and Mark was the only company who could give us what we needed and he was also the most affordable."
