Aluminium Windows for Grantham homes and sites
Windows are usually a whole-house order rather than a single opening, which means colour consistency and survey accuracy matter more than lead time. We make every frame to your surveyed sizes in one batch so the colour and finish match across the property.
We supply aluminium windows across the NG postcode area and the rest of Lincolnshire — Newark-on-Trent, Melton Mowbray and Stamford are all on the same delivery run, so if you are coordinating more than one property it is worth ordering them together.
Getting it to Grantham
- 5–12 working days from confirmed sizes
- Our own fleet on scheduled regional runs — 72 miles south-south-east of Leeds, about 1½ hours on the M1 and A1
- We survey in this area on planned visits — we will group your survey with other work nearby, which normally means a slot inside a week or two.

Aluminium Windows in Grantham — questions we get asked
What U-value can I get on aluminium windows in Grantham?
From 1.4 W/m²K depending on the glass specification, which comfortably meets current Building Regulations for replacement windows. We will confirm the exact figure for your glass build-up on the quote.
Can I have different colours inside and out?
Yes — dual-colour is a standard option. A dark exterior with a white or light grey interior is the most common combination, and it costs less than you would expect.
How quickly can you deliver aluminium windows to Grantham?
5–12 working days from confirmed sizes. Grantham is roughly 72 miles south-south-east of our Leeds factory — about 1½ hours on the M1 and A1 — so delivery is by our own fleet on scheduled regional runs. You get a guaranteed fixed delivery date rather than a courier window.
Do you offer trade prices on aluminium windows in Grantham?
Yes. Installers, builders and fabricators across the NG area — Grantham, Newark-on-Trent, Melton Mowbray and Stamford — can open a trade account for published trade pricing, a named contact, and delivery to site or yard.
