About us
Makers first, and it shows
We are a North West company that makes windows and doors, fits them properly and stands behind them afterwards.

Who we are
A factory, not a call centre
Northwest Window Co. is built around its own workshop, where our team has been making uPVC windows and doors for more than 20 years. Profiles are cut, welded, fitted with hardware and glazed under one roof, then checked before they leave.
Making the product ourselves changes how we deal with customers. We can tell you exactly what is in a window because we put it there. We can turn an order round quickly because we are not waiting on anyone else. And if something needs putting right, the people who can fix it are down the corridor.
Alongside our own uPVC frames we supply and install composite doors, aluminium windows and doors, conservatories and commercial glazing, sourced from manufacturers we know and trust.
What we stand for
Four things we will not compromise on
One honest price
No commissioned salespeople, no pretend discounts and no pressure. You get a clear, itemised figure in writing.
Made to measure
Every frame is made for the opening it will fill. Nothing comes off a shelf and nothing is made to fit with filler.
Fitted with care
Dust sheets down, old frames taken away, sealed and finished neatly inside and out, and the house left clean.
There afterwards
A 10-year guarantee on our uPVC frames, in writing, from a company you can walk into.

Come and see
A showroom where you can open and close things
Brochures and screens only go so far. At our showroom you can see the frame colours in daylight, compare handles, feel how a tilt-and-turn window moves and look closely at the finish on a composite door.
There is no hard sell. Have a look round, ask whatever you like and take a quotation away with you.

Homes and trade
The same care, whoever is buying
Homeowners come to us for a fitted job from survey to sign-off. Builders and installers come for frames made to their sizes, quickly, at trade prices. Both get the same product from the same benches.
