Aluminium Windows for Whitby 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 YO postcode area and the rest of North Yorkshire Scarborough, Malton and Middlesbrough are all on the same delivery run, so if you are coordinating more than one property it is worth ordering them together.

Whitby carries a lot of period and conservation-area stock, so colour and section profile tend to matter more here than raw specification. We can match a RAL colour to existing joinery and supply heritage-style detailing where a planning officer needs it.

Whitby is coastal, so specify the marine-grade coating. It is the difference between a coating guarantee that means something within sight of salt water and one that does not.

Aluminium Windows in Whitby — questions we get asked

What U-value can I get on aluminium windows in Whitby?

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 Whitby?

5–12 working days from confirmed sizes. Whitby is roughly 61 miles north-east of our Leeds factory — about 1½ hours on the A64 and A63 — 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 Whitby?

Yes. Installers, builders and fabricators across the YO area — Whitby, Scarborough, Malton and Middlesbrough — can open a trade account for published trade pricing, a named contact, and delivery to site or yard.
