How we handle sand mastic in Stowting
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant and we’ll explain which is best for yours. We work on brick reveals, timber door frames and period & listed homes, and the jobs we see most are old sand mastic that has cracked, crumbled or fallen out and patchy fillers round a sash window.
Outdoor sealant needs dry, clean surfaces, so work on frames around Stowting is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
Each job carries a 12-month guarantee.

What sand mastic looks like in Stowting
Historic houses like Westenhanger Castle (about 3.2 miles south) are a reminder that the area around Stowting has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Letting a property close to Westenhanger station? Then any sash windows need sound mastic to keep draughts and rain out. If you live in an older home near Church of St Mary, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Common problems we fix in Stowting
Sand mastic slowly weathers. It hardens, cracks and starts to come away from the frame or the masonry.
Any of these means the joints need attention:
- Silicone on a period window that looks wrong
- Old sand mastic that has cracked, crumbled or fallen out
- Failed mastic on an exposed elevation
- Old cement repairs round a window that have failed
Schools such as Stowting Church of England Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
What to look for in a quote
- Are they insured?
- Whether all the old sealant comes out first
- When the joint can take water or movement
- How long the guarantee is
How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Ask the planning authority about consent for listed or conservation-area homes
- Look over the window mastic once a year
- Avoid heavy scraping on the mastic joint
- Don’t run silicone over sand mastic
When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens.
Stowting questions
Do you work for landlords with property near Westenhanger station?
Yes. We work for landlords and letting agents as well as homeowners. You can call 0345 464 0079 or email us with the details for a clear quote.
Will you come out to Stowting?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Are you ARBOMaster approved?
Yes. We are an ARBOMaster approved applicator.
Do you take out the old sealant first?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.
When will the new mastic be hard?
A skin forms quite soon, but full hardening takes longer. We will explain what to expect before we leave.
Are you insured?
Yes. We are fully insured, with over 20 years’ experience in sealant work.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Do I need permission for sand mastic on a listed building?
Check with your local planning authority. They decide whether consent is needed.

Surface by surface
Tenement and terrace windows
Where a building is shared, window work may involve neighbours, so check who is responsible first.
Period and listed homes
On a listed home or in a conservation area, the right material matters. Like-for-like sand mastic is generally favoured.
When it isn’t the sealant
Some problems need a builder, plumber or other trade rather than us:
- Sash cords, weights and draught-proofing of the sashes
- Decayed frames that need repair
- Decisions on consent for listed homes
If in doubt, call 0345 464 0079 or email us and we’ll say what we think before you book.
