I wanted to wait a few months after installation, before leaving this review. I have been very happy with the quality of the windows and the installation. BWC did exactly what they said they would do and charged exactly what they quoted. These weren't the cheapest product but I genuinely feel I got a product and installation that justified the cost. We went with the timber alternative flush casement windows and have no regrets with choosing Barnet Window Company. The installation work was also of a a very high standard, they did a ground floor front and back in just 2 days. The original pebble dash has been closely replicated to allow for a very neat and tidy, external finish. Door and windows work perfectly and the house is significantly warmer and more secure. They even suggested some extra touches like angled sills that would allow the French doors to open wider. They came back on a couple of occasions to ensure we were happy and we have now had them in for a couple of months without any issue.
