“May I thank you, your team for the great job of replacing all of our windows. The boys worked so hard despite the extreme heat and did a thoroughly professional job. The disruption was minimal, I would recommend your company without hesitation. Good luck, best wishes to all”

Joy & Peter Martindale

“I wanted to write to you and your team for the swift supply and installation of new double glazing windows for the entire flat. I’m very pleased with the appearance; they are, as you promised, ‘A rated products’ both visually and, I’m sure, performance wise.”

Richard Mutton

“Just a short note of thanks, for the efficient installation of porch and windows earlier this week. I cannot heap enough praise on John and his brother for the skilled work they undertook. Nothing was too much trouble, their craftmanship was superb, and their cleaning skills legendary. All rolled in with a great sense of humour.”
