South East London's trusted team for windows & doors 

"Have recently had Windows installed by this company who were recommended to me by friends, I cannot speak highly enough of this company from the I installment of the windows to the follow up service was excellent. The guys who fitted them were very professional and helpful I live in West London and the company are in Kent but they came back twice to me for minor problems which was nothing to do with them. Would definitely recommend them to anyone, thanks sdg."

"I recently used this company and I am really pleased with the work they did. We agreed a price for the work within a few minutes. The workers arrived promptly each day, were polite, cleaned up themselves and the rubble was cleared at the end of the job. The windows and doors look great. I would definitely use this company again and recommend them to anyone wanting a hassle free job done well and with minimum disruption for a reasonable price."

The price was very reasonable and good advice was also given as to whether my ideas were going to be a good one. The company undertook the work at my house and I should say hats off. I highly recommended them."

"The double glazing units are of a very high quality. They came on time and replaced two bathroom windows in about three hours. They cleaned up well and left everything neat and tidy. Their price is very competitive and their work has an excellent finish, I would definitely recommend them!"

- Mr Nick

"Very reasonably priced and quality windows. No hard sell. I chose the windows I wanted and the openings I wanted. They did not try to convince me to buy more expensive ones and gave me a few days to think about it before placing my order. The installers were fast and efficient and cleaned up the mess. Very impressed."
