Choosing uPVC flush sash windows

The flat frame line is the starting point.

Flush appearance

The sash closes level with the outside frame. Look at the whole elevation when choosing where openers and fixed panes sit.

Colour and hardware

White, coloured and timber-effect foils change the appearance of the frame. Compare them with handle finishes using actual samples.

Glazing bars

Bars divide the glass visually. Their position should follow the proportions of your windows and any adjoining windows you are keeping.

Buckingham

Buckingham homes, and what to check first.

The homes. Much of Buckingham's centre was rebuilt in brick after the fire of 1725, which gives the town its Georgian core, with Victorian streets and newer estates around it.

What that means. In the centre, windows need to respect the Georgian proportions of the houses. Slim frames, sliding sash and flush styles and heritage colours are the usual choices there.

Check first. The town centre is a conservation area with many listed buildings. Check the status of your house before you choose a style or material.

Your questions

Buying uPVC flush sash windows in Buckingham.

Product choices, pricing and what happens before we fit.

What is the difference between flush and standard casements?

A flush sash closes level with the outer frame on the outside. A standard casement sash projects from it. Both open on hinges; the choice changes the frame lines you see from the street.

How do I get a price for uPVC flush sash windows?

Build your price online using approximate sizes, or book a free consultation and we price the job with you. Both use the same software and price list. Once you decide to go ahead, a technical survey confirms the measurements and fitting details before anything is made.

Do you supply and fit in Buckingham?

Yes. We cover Buckingham and its MK18 postcodes from our Milton Keynes base, and everyone who surveys and fits works for us. Nearby, we also fit uPVC flush sash windows in Stony Stratford, Whitehouse and Aylesbury.

Do I need permission to replace windows in Buckingham?

Buckingham is covered by Buckinghamshire Council. Listed buildings need listed building consent for new windows or doors, and in the conservation area a change of style or material may need planning permission. The newer estates are usually permitted development.

Great service from Fenster Glazing, very happy with our new bi-fold door, glass door and windows (with built-in blinds) There was an issue with the wrong spec of glass provided to them from their supplier, so they had to temporarily board up a door and a window, but this was put right within a few weeks. Recommended, thanks.
