Double glazing, windows and doors in Halifax
Calder Windows in Halifax
We're Calder Windows, a family-run window and door company. From our showroom on Normanton High Street, around 35 minutes from Halifax along the M62, we've been fitting double glazing, composite doors, conservatories and extensions across West Yorkshire for over 30 years.
We fit in Halifax town and across Calderdale, including Shelf, Northowram, Southowram, Hipperholme, Lightcliffe, Brighouse, Sowerby Bridge, Illingworth and Ovenden. Wherever you are, we'll come out, measure every opening and give you a written quote.
Halifax homes: stone, hills and weather
Halifax is built on steep hillsides, mostly in local stone, and a lot of it faces whatever the Pennine weather throws at it. That changes what a good window or door job looks like here.

Stone terraces on the hillsides
Rows of stone terraces step up the slopes all around the town. Openings are rarely square, and the frame has to be sealed properly to the stone to keep wind-driven rain out. uPVC casement windows and a solid composite front door are the most common jobs.

Victorian villas around Savile Park and Skircoat
Larger stone houses with tall openings, bays and wide front doors. Sliding sash windows and flush sash casements keep the proportions the house was built with.

Weavers' cottages in the villages
Many of the older cottages in Calderdale's villages have long rows of small windows divided by stone mullions, built to give hand-loom weavers as much light as possible. Each opening is a slightly different size, so we make each frame to fit its own opening and leave the stone untouched.

Semis and newer homes
Shelf, Hipperholme, Lightcliffe and Brighouse have plenty of semis and newer homes. Casement windows, bay window replacements, new front and back doors, and patio or bifold doors on rear extensions.
Conservation areas and listed homes
Parts of Halifax and many of the villages around it are conservation areas, and a lot of older stone houses are listed. If your home is one of them, the rules on windows and doors depend on the building and the street. Some allow well-matched uPVC flush sash or sliding sash windows. Listed buildings usually need timber and consent first. We check before we quote and tell you plainly what's allowed.

Windows built for hillside weather
On an exposed Halifax street, the details matter more than the brochure.
- Drainage and seals - Wind pushes rain sideways into frames. Good drainage channels and a proper seal between frame and stone keep it out.
- Locks and hinges that stay tight - Multi-point locking on every opening window and door keeps the sash pulled tight against the seals, so it doesn't rattle or let draughts in.
- The right glass
- A-rated double glazing is our standard. 40mm triple glazing is worth pricing on north-facing and exposed walls, where the extra warmth and quiet count most.
Conservatories in Halifax
Many Halifax conservatories face long, cold winters with a roof that was never built for them. A
tiled warm roof
turns a room you avoid into one you use all year, and it usually costs far less than starting again. Planning a new one? We build
traditional conservatories and orangeries too..

Can you fit uPVC windows in a stone cottage?
Yes, in most cases. We make each frame to fit its own opening. If the cottage is listed or in a conservation area, we check the rules first.

No. Our quotes include travel within our service area.
