Bay and bowwindow replacement
Angled bays and curved bows replaced like for like, with the support checked before anything comes out.
More light, more room, and done safely
A bay window projects out from the wall in straight, angled sections; a bow window does the same in a gentle curve of narrower panes. Both are common on 1930s semis and older terraces across the North East, and both bring extra light and floor space into the room.
The photo shows one of our bay replacements: white uPVC casements with Georgian bars, set under the original decorative header and finished with a new bay sill.
Why bays need a careful survey
In many older houses, the original timber bay frame was carrying part of the weight of the wall or roof above. Take it out without checking, and the brickwork above can drop. Before a bay comes out, we check how it’s built and fit bay poles or other support where it’s needed, so the new frame is never left holding up the house.
Choosing the windows in the bay
A bay is several windows joined together, so you can mix styles:
- Casement openers in each section, or just the side panes, with a large fixed pane in the middle for the view.
- Sliding sashes, if the house was built with them.
- Georgian bars to match the rest of the front.
- A new uPVC bay sill and, if needed, a new roof or header trim above.
Bow windows
A bow is made from more, narrower frames set at shallow angles to form a curve. It’s a softer look that suits cottages and some post-war homes. The survey and support checks are the same as for a bay.

Common questions
Can’t see your question? Call 07733 408235 and ask.
What’s the difference between a bay and a bow window?
A bay has straight sections set at angles, usually three. A bow has more, narrower sections forming a curve. Both project out from the wall.
Will the wall above my bay need support?
Sometimes. In many older homes the original bay frame carries load from above. We check at the survey and fit bay poles or other support where it’s needed.
Can you replace just one section of a bay?
It’s possible, but it’s often hard to match an older frame’s colour and profile. We’ll tell you honestly whether a full replacement makes more sense.
