We initially were unsure where to start but the glassatwork web site explained everything we needed to know. It is a very good site which clearly explains the options available and gives a good indication of pricing along the way. On contacting the support team we were assisted through the whole process with expert knowledge and courteous manners. Nothing was too much from start to finish. We were extremely pleased with the service, knowledge, professionalism and speedy installation and on a whole it was a real pleasure to do business with this company.
