Paula DELVE
Kitchen Renovation
★★★★★
“I couldn’t be more happy with my kitchen renovation. Carl and Chris have been great. They kept me updated at every stage of the renovation. The work was carried out on time, on budget and in a professional manner. I would not hesitate to ask Glassar Projects to complete any future work in my property.”
Marie Gettings
Extension & Loft Conversion
★★★★★
“An experienced and accomplished project manager, he has very good communication skills, listening and keeping people updated on progress. He has built up a great team of trustworthy tradespeople. This was an ambitious project, involving conversion of large roofspace in big Victorian semi. All was completed to an extremely high specification.”
Colin Dorricott
Home Renovation
★★★★★
“Carl and the team were quality from start to finish. They were courteous whilst in the house and kept in touch throughout. When extra things came up they were upfront about costs and there were no issues. After it was finished a few bits needed tweaking and they came back to do so without hesitation.”
Paul Kristiansen
Garage Conversion
★★★★★
“Chris and Carl were amazing from start to finish. They converted our garage into a level access bedroom and wet room. The end result was amazing and much more than we ever had imagined. We can not fault how clean they kept our property during the work and how well everything was managed. True professionals.”
Emily Griffiths
Two Storey Extension
★★★★★
“Two storey rear extension including new kitchen, bathroom and en suite, Allerton. Couldn’t be happier with the end result. The quote was very reasonable and they were able to start within weeks. The whole build went really smoothly and was finished on time and to a very high standard. The house has been completely transformed.”
Janet Hudson
House Extension
★★★★★
“It was great to have a company that just got on with the job of extending my house, who listened to my ideas, made suggestions when appropriate, then efficiently and quietly just got on with the job! I have recommended this company to all my friends who are as happy as I am with the standard of their work at a very fair price.”
