What gets replaced in County Durham, and why
Colliery terraces, interwar semis, and stone-built market-town stock. Cool, exposed, with real wind load on the higher ground.
The failure that shows up first here is Condensation and cold-bridging where cavity insulation was retrofitted around old frames. A large proportion of solid-wall stock — reveal detailing matters at replacement.
Because there is no surveyor to book and no fitting team to queue for, the lead time is about a week rather than the 8–12 weeks that is normal in this trade. On a supply-only order you notify your own building control and pay their fee — there is no FENSA or CERTASS certificate, because no registered installer was involved. What that means in practice. If we install, we certify.
Send the structural opening sizes and the design code and you will have a written price back, normally the same working day.

Delivery to County Durham — questions
Who notifies building control on a supply-only order in County Durham?
You do. Replacement windows and external doors are notifiable work, and with no registered installer involved there is no FENSA or CERTASS self-certification. If we install, we certify.
What size do I order to?
The structural opening — brick to brick, lintel to cill. Measure in three places and use the smallest figure. Do not take a fitting tolerance off yourself; that is done at our end.
Which postcodes does that cover?
County Durham covers DH1, DH2, DH3, DH6, DH7, DH8, DH9, DL1, DL12, DL13, DL14, DL15, DL16, DL17 and 21 more. Anything outside that list is still delivered — it just prices differently.
What usually needs replacing in County Durham?
Condensation and cold-bridging where cavity insulation was retrofitted around old frames. That is the pattern across most of the county, though an individual property can differ.
Is there a minimum order for County Durham?
No minimum on the product. Delivery is priced by area and size of load, so a single unit to County Durham carries a delivery charge that a full house of windows effectively absorbs.
Can I get a price without giving you my details?
Prices are published on the product pages with an inc and ex VAT switch. For your exact sizes we need to price it, but you can see the range before you speak to anyone.
