WINDOWS FOR LEWISHAM
Traditional details that belong to the property.
Lewisham’s varied period homes include Victorian and Edwardian terraces, particularly around Brockley, Forest Hill and Hither Green. Timber joinery can maintain character while improving comfort.
Compare the upper-floor windows, front bays and rear openings, particularly where earlier replacements have made the facade inconsistent.

Windows worth choosing carefully.

Good windows start with the details.
Every property is different. After you get in touch, we’ll call to find out what you have in mind and whether a visit would be the right next step.
At a visit, we can examine the existing joinery, discuss sash dimensions, glazing and decorative details, then prepare a more considered quotation. If the property is listed or in a conservation area, any necessary consents should be checked with the relevant local planning authority before work is agreed.
Get in touchYOUR QUESTIONS
Useful things to know.
Can new timber windows match the originals in Lewisham?
We can discuss proportions, glazing bars, meeting rails, mouldings and other details that help a new window suit its property. A home visit can help us judge what is achievable.
Do I have to book a visit immediately?
No. Start by getting in touch. Someone from Box Sash will call you to learn about your project; if a home visit is appropriate, we can discuss arranging one.
Do conservation-area restrictions affect windows?
They can, particularly for visible changes on historic buildings. Rules differ by property and location. Check the relevant council and any listed-building status before beginning work.
Do you make uPVC windows?
No. Box Sash specialises in authentic timber joinery manufactured in Britain.
