Choosing aluminium sliding doors
Choose the view and the clear opening together.
Tracks and panels
A sliding panel moves behind another pane. The number of tracks and moving panels determines how much of the overall width opens.

Flitwick homes, and what to check first.
The homes. Flitwick grew from a village into a commuter town around its station on the Midland Main Line, and most of its homes date from the 1960s onwards, from post-war houses to recent estates.
What that means. Most homes here are straight replacements. The big choices are usually the glass, the colour and whether to open up the back with new garden doors.
Check first. On the newer estates, check your deeds for covenants on the front elevation before changing its style or colour.

Buying aluminium sliding doors in Flitwick.
Product choices, pricing and what happens before we fit.
How much of a sliding door opening will be clear?
It depends on the number of panels, the track arrangement and which panels move. Sliding panes overlap when open. We can compare configurations against your approximate opening width before technical survey.
How do I get a price for aluminium sliding doors?
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 Flitwick?
Yes. We cover Flitwick and its MK45 postcodes from our Milton Keynes base, and everyone who surveys and fits works for us. Nearby, we also fit aluminium sliding doors in Ampthill, Toddington, Bedford and Woburn Sands.
Do I need permission to replace doors in Flitwick?
Flitwick is covered by Central Bedfordshire Council. Replacing windows and doors like for like is usually permitted development; on newer estates, check your deeds for covenants 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.
