"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"

"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."

"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."

"Tony was great to work with. He provided accurate estimates for the job. He ran HDMI cable through the walls to my new tv and receiver. He found a way to do this without putting holes in the walls. He also installed a tv in my garage and family room. Lastly, Tony recommended a universal remote for my components which works great. Thanks again, Tony!!"
