How we handle sand mastic in Burstow
If your home is listed or in a conservation area, check with your local planning authority whether consent is needed for work to windows. Like-for-like sand mastic is often the preferred finish. We work on sash and case windows, tenement windows and period & listed homes, and common reasons people get in touch are cement or filler used on old window joints that has cracked and gaps between timber frames and stone or brick.
Somewhere as small as Burstow, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
All our work comes with our one-year guarantee, wherever you are in Surrey.

FAQs for Burstow
Do you cover Burstow for sand mastic?
Yes, Burstow is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear price.
Is Burstow within the area you cover?
Yes. Burstow is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Should I use sand mastic or silicone?
For period timber windows in stone or brick, sand mastic is often the better fit. Modern frames normally suit a flexible sealant, and we will explain why.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.
Is it worth trying it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
How long does sand mastic take to go off?
A skin forms quite soon, but full hardening takes longer. We will tell you what to expect for your job.
Can new sealant go over the old?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Should I check with the council before work on a listed or conservation-area home?
Checking first is sensible. Your local planning authority can say if consent is needed for listed or conservation-area properties.
What else we do in Burstow
Why it’s worth doing now in Burstow
Before painting the windows, it pays to renew the mastic. Painting over failed mastic doesn’t seal it, and the new mastic is traditionally left unpainted. Older cottages and farmhouses around Burstow can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Combining jobs into one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.

Sand mastic in Burstow: local notes
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Managing a site like Oakwood School? Then its window and door frames need their mastic kept sound, just like a home’s. Homes close to Church of St Bartholomew include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

We will always be straight with you, so here’s what new sealant won’t do:
- Planning or listed building consent (your local planning authority decides)
