As standard you will receive an ultra efficient ‘A’ rated window. Our latest casement windows utilise some of the most advanced double glazing on the market. Our windows easily exceed building regulations so you will have the peace of mind that you are installing the very best double glazing.

The eco energy plus window system has achieved a BFRC (British Fenestration Rating Council) Window Energy Rating of ‘A’, the highest achievable.

The eco energy plus window system uses it’s multiple chambers to lock in the heat, and high performing bubble gasket seals to ensure there are no gaps for heat to escape.

Was recommended by a friend who had windows replaced by this company at a third of the price quoted by a well known big company. I have had a new front door and am absolutely delighted with it. I can not fault the service and will recommend to my friends. Thanks

I would like to thank the staff of Sidcup Double Glazing for doing an excellent job. They were very professional and punctual. The team who installed the windows were very good tradesman. The rooms were left spotlessly clean. I have no hesitation in recommending Sidcup Double Glazing. From Garry’s visit to my property to price the job through to completion of the work they are to be commended.

We had several windows replaced (2 bay windows plus 3 others) and decided to go with Sidcup Double Glazing. The first visit was very professional and the quote was competitive. For all appointments they showed up on time and the job was finished a day early. Staff is very friendly and respectful of the house. Everything was cleaned up afterwards and we couldn’t be happier. The windows look great. It is a family run local business and we would go back to them anytime.
