Croston's range of PVCu windows provide you with a maintenance free alternative to timber with the additional benefits of increased comfort and security.

We install the highest quality UPVC windows on the market, in the form of the Spectus Elite 70mm profile. The care taken throughout each installation provides us with the confidence to offer a comprehensive 10 year guarantee which is backed by the Independent Warranty Association to provide you with the ultimate piece of mind.

Whether you are looking for a bay, bow, casement or tit and turn window, we can create a design of almost any size of shape with a combination of fixed and opening panes to suit your needs and the character of your home. Other design features available include Georgian bars and decorative run through sash horns, as well as the option of a classic Bevelled profile or the elegant curved Ovolo profile.

Our frames are reinforced with galvanised steel to provide structural rigidity making your home safe and secure. Elite twin cam security locking from the DGS Group offers more than double the security of industry standard products.

If you are looking to replace an existing bay or bow window, or convert from a flat casement, you can be assured that our bay windows are constructed using reinforced corner posts which provides strength.

What our customers' say...

"The price was very competitive and the service was great from start to finish. The fitting was done to a very high standard with no mess to clean up afterwards. I would certainly recommend Croston Conservatories to anyone. I have used this company to replace all my windows and have never had any problems."
