uPVC and Sash Windows in Bicester

If you’re looking for new windows and doors in Bicester, our range of double glazing and stunning replacement doors can bring out the best in your home, whether you are looking to sell and maximise asking prices or you’ve just moved in and want to add your mark.

Bicester includes some modern housing developments these days, but it has a long history. Today, it’s rapidly expanding, well-connected transport-wise and the variety of its housing stock reflects its proud heritage, incorporating everything from 1950s, ‘60s and ‘70s homes to the more recent estates on Bicester’s outskirts. There are townhouses, terraces and cottages, too.
The old town centre, a conservation area, has many Grade I and II listed properties suiting vertically sliding sash windows – popular since the 1700s and 1800s for their sheer elegance, and to which our solutions add modern technology. Meanwhile, low maintenance, versatile and strong aluminium or affordable, secure and durable uPVC could be ideal for a twentieth century home in Bicester.
Whatever you’re looking for when replacing your Bicester doors and windows, or if you’re after a conservatory here, we can help. Talk to us today and request a free, no obligation estimate.

Conservatories in Bicester

Conservatory Styles

Conservatories in the Victorian or Edwardian style, as well as lean-to models, remain popular with our customers and tend to suit older properties. You could have full-height glass walls or dwarf walls with glass. Orangeries are another option, originally devised to cultivate orange trees, and which have solid walls inset with glazed panels or full-length doors and a glass roof. They tend to be rather more substantial structures. Contemporary conservatories tend to be bespoke designs, with a wide choice of styles and materials available. And modern ones can even work well alongside period buildings, as long as they are sympathetically designed.

At Isis Windows, we offer orangeries and sunrooms, Victorian and Edwardian conservatories and bespoke designs together with a great selection of stunning roofing options. And our products and service come with a full guarantee, giving you genuine peace of mind. Remember, most of our business comes from personal recommendations.
