Sion Dean10/03/2019Great Service! I have used Decorative Glass & Glazing twice, and on both occasions they have been great. They are friendly, attentive and above all do a very good job at a fair price. They are extremely clean and tidy, when they left you wouldn’t know they had been there, except for my nice new windows. I highly recommend this company.
