Aluminium Windows for Sevenoaks 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 TN postcode area and the rest of Kent — Tunbridge Wells, Bromley and Croydon are all on the same delivery run, so if you are coordinating more than one property it is worth ordering them together.
Sevenoaks 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.

Aluminium Windows in Sevenoaks — questions we get asked
What U-value can I get on aluminium windows in Sevenoaks?
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 Sevenoaks?
10–20 working days from confirmed sizes. Sevenoaks is roughly 189 miles south-south-east of our Leeds factory — about 4½ hours on the M1 and M25 — so delivery is by planned long-haul runs or palletised freight, depending on order size. Larger orders go on a dedicated run; smaller ones travel palletised on a tracked service.
Do you offer trade prices on aluminium windows in Sevenoaks?
Yes. Installers, builders and fabricators across the TN area — Sevenoaks, Tunbridge Wells, Bromley and Croydon — can open a trade account for published trade pricing, a named contact, and delivery to site or yard.
