About our sand mastic in Steeple Barton
We work across Steeple Barton renewing sand mastic on sash windows and doors. Each joint is raked out, prepared and pointed by hand for a neat, traditional finish. If you’re dealing with window mastic to renew ahead of painting and modern sealant on a period surround, we can put it right, on period & listed homes, stone surrounds and brick reveals alike.
Around Steeple Barton, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
Our work is backed for twelve months.

Common questions in Steeple Barton
Do you cover smaller places like Steeple Barton?
Yes. Steeple Barton is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is Steeple Barton in your area for sand mastic?
Yes. We work across London and the South East, and Steeple Barton is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear quote.
What guarantee comes with the work?
There’s a 12-month guarantee on every job, sand mastic included.
Can I do it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
What exactly is sand mastic?
It’s a mix of sand and a linseed-oil-based binder. It’s applied by hand and finished to sit neatly against the masonry.
Do you have insurance?
Yes. We are fully insured.
Is there any odour?
It depends on the product. Some smell for a while, some hardly at all.
Is it OK to seal over old sealant?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
Do you need sand mastic in Steeple Barton?
Over the years, sand mastic weathers. It dries out, cracks and loses its grip on the stone or timber.
Keep an eye out for these signs:
- Wind and rain getting in round a sash window
- A silicone bead on a sash window that spoils the look
- Patchy fillers round a sash window
- Weathered mastic on the most exposed windows
Managing a site like Middle Barton Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.
What to look for in a quote
- When the joint can take water or movement
- Who turns up on the day
- Whether they’re fully insured
- What happens if they find a problem under the old sealant
What the job involves on each surface
Period and listed homes
Many older homes were built with sand mastic round the windows. If your home is listed, ask your local planning authority about consent.
Tenement and terrace windows
Where a building is shared, window work may involve neighbours, so check who is responsible first.
When it isn’t the sealant
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Damaged stone surrounds
- Decisions on consent for listed homes
- Broken panes
If in doubt, ring 0345 464 0079 or email us and we’ll say what we think before booking.
Surfaces we seal
- Brick reveals
- Sash and case windows
- Tenement windows
- Stone surrounds
- Timber door frames
- Period & listed homes
Leave it or put it right?
Filling over old, loose mastic does not last. We remove the loose material first so the new work lasts. In a small place like Steeple Barton, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
What you pay reflects the work, not guesswork. That is why we ask a few questions first and send you a clear quote before we start.
