Surveys and fitting in Durham
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.
Durham has a significant conservation-area and period property stock. Where a planning officer is involved, heritage colours and slimmer heritage-style sections usually get approval where a standard modern frame will not — send us the address and we will tell you what tends to pass locally.

Durham — common questions
Do you deliver aluminium doors and windows to Durham?
Yes. Durham is about 68 miles due north of our Leeds factory — about 1½ hours on the A1(M) — so your order travels by our own fleet on scheduled regional runs. You get a guaranteed fixed delivery date rather than a courier window.
How long does an order for Durham take?
5–12 working days for a standard order in Durham, measured from the point your sizes are confirmed. We make everything ourselves in Leeds rather than buying in finished frames, which is why the lead time holds. The 68-mile run down the A1(M) is the only part outside the factory.
Do you survey in Durham?
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.
Can trade customers order from Durham?
Yes — trade pricing is available to installers, builders and fabricators in Durham, Bishop Auckland, Sunderland and Gateshead and across North East. Trade accounts get published lead times, a named contact, and delivery to site or to your yard in the DH area.
