Your trusted local double glazing installer in Chelmsford
We’re based at Warners Farm in Howe Street, on the main road between Chelmsford and Great Dunmow. Most of Chelmsford is a short drive away, so we can get out to measure up quickly and come back if anything needs looking at once the job’s done.
Our showroom has windows, front doors, French doors and bi-folds set up as working displays, including the Gerda range of front doors. You can open them, try the handles, compare colours and finishes, and talk through your home with the people who will be fitting it.
Every installation is carried out by our own fitters. We never pass work on to subcontractors, so you deal with the same team from the first visit to the final clean-up.

Double glazed windows for homes in Chelmsford
Chelmsford has a real mix of houses, from Victorian terraces near the city centre to 1960s and 70s estates in Springfield and Great Baddow and new-builds at Beaulieu and Channels. We’ll recommend a window style that suits the age of your home, and match the original look where it matters, such as keeping glazing bars on a period property.
Every window is made to measure and fitted by our own team. You can see each style below in the showroom before you decide.
uPVC casement windows
The most popular choice for homes in Chelmsford. Side or top opening, in white, woodgrain or colours such as anthracite grey, with secure locking handles.
Sliding sash windows
The traditional look of a timber sash without the draughts, rattles and repainting. If your home is in a conservation area, check with Chelmsford City Council before you replace original sashes.
Bay and bow windows
We replace bay and bow windows as a complete unit, made to follow the exact shape of your existing bay so the outside of the house looks as it should.
Aluminium windows
Slimmer frames and more glass, in colours such as anthracite and black. A good match if you’re also having aluminium bi-folds or sliding doors fitted.
Front, back and patio doors we fit in Chelmsford
A new front door changes how your house looks from the street, and a wider opening at the back changes how you use the garden. We fit composite and Gerda front doors, French doors, sliding patio doors and aluminium bi-folds across Chelmsford, from a single back door to a full-width opening in a new extension.
The showroom has working displays of each type, so you can try the handles, locks and sliding gear before you choose.
Composite doors in Chelmsford › · Patio doors in Chelmsford ›
Composite and Gerda front doors
Solid, well insulated and low maintenance, with a wide choice of colours, glass and handles. Gerda is our premium high-security range, with several on display in the showroom.
Aluminium bi-fold doors
Fold right back to open a kitchen or extension onto the garden. Slim frames in anthracite, black or white, set up to open the way you want.
Sliding patio doors
Large glass panels that slide past each other, so they take up no room inside when open. Available in uPVC or aluminium.
French doors
A pair of doors that both open fully, with or without glazed side panels. A good fit for period homes and smaller openings onto a patio.

Common questions about double glazing in Chelmsford
How much does double glazing cost in Chelmsford?
It depends on how many windows or doors you need, their size, the material and the glass and hardware you choose. We give every Chelmsford customer a free, fixed quote, online, by WhatsApp or at your home, so you know the full price before you decide.
Do I need planning permission in a conservation area?
Replacing windows in a house with ones of a similar style doesn’t usually need planning permission. In a conservation area, or if your home is listed or a flat, the rules can be stricter, so check with Chelmsford City Council before you order. We can recommend styles that keep the original look.
How long does fitting take?
It depends on the size of the job. A front door or a few windows is often fitted in a day, while a full house or a large bi-fold opening takes longer. We’ll tell you how long your job will take when we quote.
Can I see the windows and doors before I order?
Yes. Our showroom at Warners Farm, Howe Street, just north of Chelmsford, has working displays of our windows, front doors, bi-folds and sliding doors. It’s open Monday to Friday, 9am to 5pm.
Do you use subcontractors?
No. Every job is fitted by our own team, from survey to finishing, so you know who is coming to your house.
