This is the second time we’ve used Diamond, they’ve excelled once again. Their estimator turned up on time and gave us exactly what we asked for, with helpful advice offered. The quote wasn’t cheap but wasn’t too expensive, either. They employ clean, tidy, careful, polite, friendly and truly conscientious workmen – grafters, who know how to produce a quality finish. All work done to our complete satisfaction, the end result is stunning! We can’t stop admiring our new windows! Faultless service, highly recommended – a terrific local company, worthy of their excellent reputation.
