Double Glazing in London

See below for a list of glaziers near you. Many of these local window and door experts have been rated and reviewed by people in your area, making it easy for you to enquire about double glazing prices and hire a trader that your community trusts.

What is double glazing?

Double glazing, or double-pane glazing as it is often called, is a great way to insulate your home and save money on your energy bills. It’s also great for preventing draughts and reducing noise pollution from external sources such as road traffic in busy areas.

How does double glazing work?

Generally double glazed windows will consist of two windows separated by a vacuum or gas which is sealed within the cavity between the two panes of glass. This doesn’t just help with heat loss, it also helps with temperature regulation, meaning your home will be warmer in the winter and cooler in the summer months.

Double glazing is often paired with UPVC frames which are well known for their durability, heat retention and protection against outside elements such as the weather.  Wooden and aluminium frames are also a common option, helping you to modernise your home without compromising on your existing style and features.

Double glazing advantages

There are many other advantages of double glazed windows and doors, such as increased security for your home (if you opt for toughened glass). You can also reduce condensation, helping to minimise the risk of mould and mildew problems and general damp prevention. Double glazing is also a desirable factor for home buyers, meaning an investment in new window and door glass is likely to increase the resale value of your home.

    • After much deliberation my wife and I decided to have our aged windows replaced and on a recommendation we visited the showroom/shop of WJ Richardson in West Wickham. It was the best thing we could have done as from the initial contact to the completion of the job their service was first class. Just before they was to start we were given a 'plan of action' which meant we could prepare the respective rooms the day before. The 4 man team arrived just after 9am each day and were a pleasure to have around. Easy to get on with answering any questions we had, they were polite and very respectful of our home environment leaving the minimal amount of clearing-up to be done. Their workmanship was top class. The windows look superb. Thank you to all concerned. I would thoroughly recommend WJ Richardson to anyone thinking of have replacement windows

    • I was absolutely dreading having two new windows fitted, one in the kitchen and one in our second bedroom. WJ Richardson had been recommended to be my somebody else on our block could use them to do sliding doors. They couldn't have been better. The two theatres arrive promptly at 9 AM and were courteous and smiling and helpful throughout the day. They absolutely made a minimum of mess, cleared up after them, did a brilliant job, and the windows look absolutely fantastic. I am absolutely thrilled and would heartily recommend them

    • One word for this Company Awesome! They have just replaced all my windows and doors. My fronts were large bay windows. From the initial survey to the finish this company has been 100% Professional. The 2 men who did all of the installation were Brilliant, Paul and Gary were always happy, professional and advised us each day of what they were doing next. The workmanship and quality of the windows is first class as well as the installation. I would recommend Lifestyle to everyone. A rarerity in this day and age is you get a personal service and you are treated with total respect by all the company. If anyone is considering any work I would recommend Lifestyle with out a second thought. Finally I would like to say to Lifestyle, Paul and Gary thank you so much for a Fantastic job and will always recommend you and use you for any other work I might need doing.

    Soffits are found under fascia boards and they are not usually visible at street level. Soffits can be ventilated to allow for the flow of air into the underlying roof area, although some of our Sutton and Surrey clients prefer that ventilation is provided over the top of the fascia boards. At Generation Windows, all of our soffits provide excellent ventilation. Good ventilation prevents condensation from forming in the roof void, which in turn reduces the risk of timber decay. Our specialist uPVC roofline products do the job that older bargeboards and timber panels can't. In addition to fascias and soffits, we also offer guttering, dry verge products, cladding, trims and accessories.
