Aluminium Sliding Doors for Grantham homes and sites
Sliding doors suit an opening where you want the glass to stay glass — the panels slide past each other rather than fold, so you keep an uninterrupted view even when the door is shut. They're the usual choice where a bifold's stacked leaves would block a walkway.
We supply aluminium sliding doors across the NG postcode area and the rest of Lincolnshire, including Newark-on-Trent (13 miles north-north-west), Melton Mowbray (14 miles south-west) and Stamford (19 miles south-south-east).We manufacture and deliver — your own installer or builder does the fitting.

- Delivered on our own fleet to a fixed date — Grantham is 72 miles south-south-east of Leeds, about 1½ hours by road via the M1 and A1

Aluminium Sliding Doors in Grantham — questions we get asked
Are sliding or bifold doors better for my Grantham extension?
Sliding doors give you more glass and a cleaner sightline when closed, and they don't need clear space for stacked panels. Bifolds open the whole aperture. If you want the opening fully clear in summer, choose bifold; if you want the view year-round, choose sliding.
What threshold options are there?
There's a standard 47mm threshold or an eco-drain low threshold. The threshold needs detailing alongside your drainage, so decide it with your builder early and ask us for the threshold detail.
What's the lead time for aluminium sliding doors in Grantham?
2–10 working days from confirmed sizes — the same wherever you are. Grantham is about 72 miles south-south-east of our Leeds factory, and every order is delivered on our own fleet, to a fixed date confirmed when you order.
Do you offer trade prices on aluminium sliding doors in Grantham?
Yes. Installers, builders and fabricators across the NG area — Grantham, Newark-on-Trent, Melton Mowbray and Stamford — can open a trade account: manufacturer-direct pricing, no minimum order value and a dedicated account manager.
