Heritage steel window replacement in Northumberland
We design and install heritage steel window replacement throughout Northumberland, from Hexham and Morpeth to Alnwick and Berwick-upon-Tweed, with fixed written quotes after a free survey.

Fitting heritage steel window replacement in Northumberland
Northumberland's stone farmhouses and market-town houses suit robust external steel doors and sympathetic heritage windows.
Safety glass is standard in every internal pane, and we check whether fire-rated glazing is needed before anything is ordered. Lead times are confirmed in writing when you sign off the drawings, so you can plan the rest of your project around them.
We cover Hexham, Morpeth, Alnwick and Berwick-upon-Tweed, plus the villages and towns between them. Lead time is 5–7 weeks from signed-off drawings, and we confirm dates in writing when you sign off the drawings.
What we can include
- Original-style ironmongery including monkey-tail handles
- Drawings to support listed building or Article 4 applications
- Slim double-glazed units in modern thermal sections
- Horizontal and Georgian glazing-bar patterns reproduced
Heritage steel window replacement means removing failing original metal windows, typically from the 1920s to 1950s, and fitting new steel windows that copy their slim sections, glazing-bar patterns and opening lights. Read the full guide to heritage steel window replacement.

Heritage steel window replacement in Northumberland: questions
Do I need permission to replace steel windows?
If the house is listed you will need listed building consent, and some conservation areas have Article 4 directions that control window changes. Otherwise replacement is usually permitted, subject to building regulations.
Can you match curved Art Deco bay windows?
Yes. Curved and corner bays can be made in steel to follow the original radius and bar layout.
