Traditional Timber Sash Window Specialists



“I had a sash window and two floor to ceiling windows replaced with double glazed versions in a Georgian house. RG Windows were recommended by a friend and I am happy to recommend them to others. They not only offered the best price, but took that extra care and attention to detail that marks the work of a crafts person. The making good after installation was meticulous. I am an extremely satisfied customer.”
Catherine Barber, Bermondsey

“I used this company about within the last year and I was very pleased not only with the price & quality of the work but by the attention to detail - ensuring that everything was in first class working order- but in the after care service. I had a minor problem and they arrived within 24 hours to rectify it. I have no hesitation in recommending them to anybody else, in fact I have done so already to several friends, who have been equaly pleased with the work carried out for them.”
Mike Byrnes, St Margrets

“Can we take this opportunity to thank you for the fantastic job you have done in installing our replacement sash windows. We are really, really pleased with them and the finish is superb. We were also impressed with how tidy you left everything and the finishing touch was putting our curtain poles and curtains back up for us.
We would certainly recommend you to anyone and you will be our first contact should we need work doing on any of our other windows.
It was a pleasure doing business with you!.”
Christine & Dave Richardson, Kingston

“RG Windows recently carried out work involving the replacement and refurbishment of sash windows at a Grade 1 Listed Building Project I am
involved in. (Vanbrugh Castle Greenwich) I found them to be friendly and conscientious and their workmanship to be excellent. The work was completed to budget and I have no hesitation in recommending them.”
Christopher Hardinge, Architect, Greenwich

“We had given up in exasperation waiting for a joiner to give us a quote. So we contacted RG Windows who came promptly, provided a written
quotation within days, and then replaced our window on the date and time agreed. It was a neat job done to a professional standard with high levels of service.”
