Sand mastic for homes and businesses in Mulberry Green
Sand mastic does not last for ever and gaps open up round the frame. We rake it out and renew it so the surround looks right again. We work on sash and case windows, stone surrounds and brick reveals, and people most often call us about tired mastic found when preparing windows for paint and patchy fillers round a sash window.
In a village or hamlet like Mulberry Green, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
Whatever the size of the job, you get the same one-year guarantee.

What the job involves on each surface
Sash and case windows
On a sash window, the mastic joint shows on the outside so we finish it carefully.
Tenement and terrace windows
Rows of sash windows on tenements and terraces often need renewing together. We can do one window or several.
What happens if it’s left?
New mastic over crumbling mastic will not hold. Raking out and preparing the joint gives it a sound base so the new work lasts. In a small place like Mulberry Green, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Doing several joints on one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will give you a clear price for the lot.

Sand mastic in Mulberry Green: local notes
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Layer Marney Tower (about 2.8 miles south) are a reminder that the area around Mulberry Green has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
For landlords with property near Marks Tey station, any sash windows need sound mastic to keep draughts and rain out. If you look after a building such as The Stanway School, larger buildings have plenty of frames, and the mastic around each one ages. For an older house near a landmark such as Church of St Mary, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Mulberry Green: your questions answered
I let a flat near Marks Tey station. Can you help?

What’s sand mastic made of?
A traditional pointing material made from sand and a linseed-oil-based binder, used between timber frames and stone or brick.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
Do I need permission for sand mastic on a listed building?
Your local planning authority is the one to ask. They decide whether consent is needed.
Do the sealants smell?
Some sealants have a smell while they cure, but it fades. Opening a window helps.
Are you insured?
Yes. We’re fully insured, with over 20 years’ experience in sealant work.
Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Check the mastic when you check the paintwork
- Avoid patching sand mastic with silicone
- Ask a joiner to look at soft timber first
- Avoid heavy scraping on the mastic joint
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.
Landlord and commercial work in Mulberry Green
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
