"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"
