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.

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

Oldbrook homes, and what to check first.
The homes. Oldbrook sits beside Central Milton Keynes and was built from the late 1970s, with terraces, semis, flats and housing association homes along its redways.
What that means. The houses here are usually straight replacements. Flats and shared buildings follow different rules, and the landlord or management company often has a say in what is fitted.
Check first. If you own a flat or a shared-ownership home, find out who is responsible for the windows before you get quotes. In many leases it is not the occupier.

Buying uPVC flush sash windows in Oldbrook.
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 Oldbrook?
Yes. We cover Oldbrook and its MK6 postcodes from our Milton Keynes base, and everyone who surveys and fits works for us. Nearby, we also fit uPVC flush sash windows in Furzton, Shenley Church End, Great Linford and Monkston.
Do I need permission to replace windows in Oldbrook?
Most Oldbrook houses can have windows and doors replaced like for like without planning permission. For flats and leasehold or shared-ownership homes, the freeholder or housing association usually has to agree first.
What our customers say.
Real reviews from real installations. Every one is public, so you can go and check them yourself.
We have used Fensters for years on a variety of glazing work, and 2 door installations. They are competitively priced and responsive. They take great care over measuring and specifying the work, giving you a clear quote so you understand what you are getting (thanks Perry!). The fitters are all extremely competent and personable. We had to replace our front door for accessibility reasons, they gave us confidence that our requirements would be met, reproduced the intricate leaded and stained-glass pattern of our old door, and did a quality fitting job (thanks to Johnnie and Shane!). In summary they are our go-to suppliers for all replacement and repair work.
