“I chose Darren from a small group of double glazing specialists after he had, unlike the others, described and recommended repairs rather than replacement. He explained why and showed me how that would be achieved, with careful attention to my requirements as the client. Today he completed the job, replacing glass and locks where required and, while the weather conditions have improved since yesterday, I can feel the difference in temperature in that room and there is no draft. This will make a difference to the whole house and hence my heating bills. Recommended.”
