FAQs
Do I need permission to change my windows in the conservation area?
Often yes, especially for like-for-like replacement or any change to appearance. We’ll advise and prepare documents.
Can I have double glazing?
Slim-profile double glazing is sometimes acceptable on non-listed buildings if profiles/sightlines are preserved. If not, we recommend secondary glazing.
What timbers and finishes do you use?
Accoya®, engineered redwood, or hardwoods on request. Factory spray finishes or site finishing to match existing.
How long does a typical overhaul take?
A standard 4-sash terrace can be overhauled in 1–2 days once on site; full replacements vary by scope.
