Should I replace timber windows with aluminium?
Replacing timber windows with aluminium makes sense if you want less maintenance, slimmer frames and a long life. Aluminium does not rot or need repainting, but it costs more than uPVC and needs checking if you live in a conservation area or listed building.
What are the advantages over timber?
- No rot, warping or repainting cycle
- Slimmer frames and larger glazed areas, because aluminium is strong
- A long lifespan, typically 30 to 45 years or more
- Wide colour choice, including dual colour finishes
When should you keep or restore timber?
If the windows are original features of an older or listed home, restoring them may be better. Timber can last for generations when maintained, and consent rules for changes to listed buildings are strict.
Do you need permission to switch from timber to aluminium?
Like-for-like replacement is generally permitted development for houses, but not in listed buildings, and conservation areas with Article 4 directions can restrict changes to the appearance of windows. Check with the local planning authority first.
Look matters here: slim aluminium can mimic timber sightlines, but the profile you choose should suit the age of the house. Jake surveys every job himself, and JMF Windows Oxford fits aluminium windows with a 10-year guarantee and Certass registration.
