Burmarsh Sand Mastic
Traditional burnt sand mastic around sash and case windows and doors in stone and brick for homeowners, landlords and businesses in Burmarsh. Fully insured, ARBOMaster approved and guaranteed for a year.
- Wind and rain getting in round a sash window
- Gaps round a timber door in stone or brick
- Weathered mastic on the most exposed windows
What we do, step by step
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a single window, longer for several. Somewhere as small as Burmarsh, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each surround is checked first.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic is not too thick.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
How to prepare
- For business premises, tell us about site rules or sign-in
- Clear the area around the work
- Let us know if you’ve seen damp or leaks

Sand mastic for homes and businesses in Burmarsh
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s made from sand and a linseed-oil-based binder and built up by hand. On older homes, it suits the building far better than silicone. If you’re dealing with mastic round period door frames that has failed and window mastic to renew ahead of painting, we can put it right, on sash and case windows, stone surrounds and period & listed homes alike.
Around Burmarsh, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
We stand behind the work with a one-year guarantee.

Questions from Burmarsh
Does living near the coast affect sand mastic in Burmarsh?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Can you help a landlord with a rental near Westenhanger station?
Yes. We work for letting agents and landlords as well as householders. You can call 0345 464 0079 or email us with the details for a clear quote.
Do you work for hotels and businesses?
Yes. We’ve worked for hotels, offices and other businesses, and we are fully insured.
Can you seal over the old sealant?
No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.
Can you do several jobs on one visit?
Yes, we can. More than one area can be quoted together.
Are you an approved applicator?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
How long does the job take?
That depends on the amount of work, but most jobs take anything from a few hours to a full day, depending on how many windows. We will tell you when we quote.
Do you guarantee sand mastic work?
Our 12-month guarantee applies to all our work.
How the job changes by surface
Tenement and terrace windows
Upper-floor windows need access planning. Tell us the height and we’ll confirm what’s needed.
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.
What affects the cost of sand mastic
The price is agreed before any work begins. It’s based on:
- How much there is to do
- The number of rooms or windows
- Any working-time requirements on site
- Whether old sealant or filler has to be cut out
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.
Asking for a quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- The problem you’ve noticed
- The rough size of the job
- Any access issues, like height or stairs
- The type of property
For a quote, phone 0345 464 0079 or email us and tell us where the job is and what the problem looks like. You will have a clear quote before work begins.
For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Why it’s worth doing now in Burmarsh
A silicone bead can be quicker, but on period stone or brick it often looks out of place. Sand mastic suits the building and blends with the stone or brick. In a small place like Burmarsh, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.

What sand mastic looks like in Burmarsh
Burmarsh is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Historic houses like Westenhanger Castle (about 3.5 miles north-east) are a reminder that the area around Burmarsh 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.
In the older streets around Church of All Saints, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What we’re called out for in Burmarsh
Some old mastic was never deep enough. Mastic that’s too thin cracks and drops out so we make sure the new mastic is the right thickness.
Any of these means the joints need attention:
- Draughts and rain around sash boxes
- Mastic that needs renewing before redecorating
- Silicone on a period window that looks wrong
- Gaps between timber frames and stone or brick
If you let a flat or house near Westenhanger station, any sash windows need sound mastic to keep draughts and rain out.
