The uPVC casement windows we install for our customers throughout the London area look good from the inside and the outside. Using a higher ratio of glass-to-frame, they’ll reward you with clearer views of your garden, while letting in more natural light than a conventional uPVC casement window that hasn’t been engineered to the same exacting standards.
Our high-performing and aesthetically outstanding range of windows are manufactured by Liniar, an innovator and recognised industry leader in their field.
One of the key advantages of choosing uPVC casement windows for your home in or near London is that they’re easy to look after. No extensive maintenance will be required to preserve their colour or prevent them from rotting, blistering or warping. A quick wipe down with a soapy cloth is all that’s required to keep your windows looking beautiful all year round.
Decorate your uPVC casement windows using an eclectic range of astragal and Georgian bars, then select from our extensive portfolio of colouring and woodgrain foil options to achieve an effect that’s truly unique. Our specialist team will work with you throughout the design process to ensure your made-to-measure windows are a perfect fit for your home in or near London – and are built to accommodate your home improvement budget.
Whether you opt for 28mm double or 36mm triple glazing, our uPVC casement windows – when built using Liniar’s EnergyPlus profile – will help you achieve U-ratings of up to 0.8%. You can depend on the quality of their construction to block out unwanted acoustic noise and retain heat, resulting in a peaceful and warm home environment. Save money and stay warm when you choose your brand-new uPVC casement windows from BBL.
BBL understands the intricacies of the uPVC casement windows it installs for its many customers throughout London and any of its surrounding areas. We can install your brand-new uPVC casement windows on a standalone basis. Perhaps you have been looking at Lean-to or Edwardian conservatories, which need to incorporate uPVC bi-folding doors and a new roofline. Either way, contact us today for an informal discussion.

Frequently asked questions
What is the lifespan of uPVC windows?
Well-made uPVC windows typically last 25 to 30 years, and good frames can reach 35. The sealed glass units usually give up first, often somewhere between 15 and 25 years. Profile quality, installation and hardware decide the outcome more than age alone. Read the full answer
What is the average cost of a uPVC window?
There is no single useful average cost for a uPVC window, because the price depends mainly on size, opening style, specification and installation work. The only reliable figure comes from a survey and a measured quote for your actual openings, so treat any average with caution. Read the full answer
Is it worth replacing 20 year old double glazing?
Often yes, if the units have misted, the frames are warped or draughty, or the hardware is failing. Windows of that age were built to older standards than today's 1.4 W/m²K limit. If the frames are sound and only the glass has failed, replacing the sealed units may be enough. Read the full answer
Should I replace wooden windows with uPVC?
On a modern or unlisted home, usually yes: uPVC needs little maintenance and seals better than ageing timber. Keep timber, or choose a close match, where the home is listed or in a conservation area, because planning rules may restrict uPVC and some timber is worth repairing. Read the full answer
