We’ve just had windows and doors supplied and fitted by Bellwood’s and cannot recommend them highly enough. From Joe, who sold the windows to us, to Dave and Les who fitted them, we had a friendly and professional service. We’re delighted with our doors and windows …they even arranged a builder to fit a new lintel to enable a safe install of our French doors. Thank you, Bellwood’s.

Dave and Les came and fitted front/backdoor on 22/12/23. 2 great gents,very professional in their trade,doors fitted to perfection,cannot fault one bit. Would highly recommend these guys. A very happy customer.
Best window fitters I've ever had. I've had several houses and these guys are great. Joe who came round first was brill. No sale tactics or call the manager rubbish. Just an honest and straightforward price. I was impressed from the get go. The turnaround was really fast. Dave and Les fitted them over 2 days. I noticed huge attention to detail inside and out. Perfectly sealed and spotlessly clean. They also went the extra mile lifting a big frame over the roof to get it in and also serviced another door I which I wasn't changing. I think the bacon sarnies swayed that one. Great lads all round. I highly recommend them. The windows and doors themselves are perfect. Makes a huge difference to the home. Thank you all.

Window Styles

Pick the perfect new window style to suit your home. Our expert window fitters work on a variety of projects and can use a range of types and shapes to suit any home.

Modern UPVC Windows

UPVC windows are the ultimate low-maintenance solution for modern homes. UPVC, or Unplasticized Polyvinyl Chloride, is easy to clean and lasts for many years.

The material fits a variety of casement options, so you can choose the window frame style you want for your home.

Casement Windows

A casement window has a hinge on one side to allow it to open and close like a door.

Casement windows are popular with older homes, as the frame can be made from a variety of materials to enhance the traditional look.

Frosted Glass Windows

For bathrooms or rooms that face the street, misted windows are an ideal choice to ensure privacy while still letting in light.

Our frosted glass units come in a range of styles, so you can select the one that works best for your home.

Sash Windows

Sash windows are a traditional style that involves fitting two window casements, one above the other.

Each of the panes can be raised or lowered vertically for ventilation.

Our sash windows are energy efficient and made to last, so they’ll give you a traditional look with all the benefits of modern double-glazing window technology.

Bay Windows

Bay windows consist of a large protruding casement with three or more windows fitted to the frame.

A bay window installation requires more time and skill than traditional window types, but it can create a beautiful atmosphere in any room.

Bay windows are a traditional style that needs to be installed at the right angle, so working with experienced window fitters like us is crucial.

Tilt & Turn Windows

Tilt-and-turn windows are multi-functional and give you various ways to open them and ventilate your room.

To ensure tilt and turn windows work properly, you need to make sure you hire the right window fitters to install them.

Bellwood’s has been installing tilt and turn windows for many years and knows how to ensure the window frames function correctly and look great.
