"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."

"The company did an exceptional job. They provided a quote for the work and with each encounter they were always on time. Within a few hours my garage had power, outlets were setup, and an external light was in place. Work by the employees went on non stop and the site was cleaned very well when they were done. I would absolutely use their services again and recommend them without hesitation for anyone in need of electrical work."

"Mark was exceptional. We reworked the scope of work several times to fit my budget and evolving needs as we decided to change our entire plan for the basement. The work he did was exceptional. I would definitely hire him again."

"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!!"
