Sand mastic in Bredgar
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s a mix of sand and a linseed-oil-based binder, applied by hand. On period homes, it looks right where silicone wouldn’t. We work on timber door frames, sash and case windows and stone surrounds, and the jobs we see most are mastic that needs renewing before redecorating and open joints round the window box.
Homes in small places like Bredgar often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
We stand behind the work with a 12-month guarantee, so you’re covered after we have gone.

What we’re called out for in Bredgar
Water gets into small cracks in the mastic and loosens it further. Exposed elevations usually fail first.
The most common problems we see are:
- Tired mastic found when preparing windows for paint
- Cement or filler used on old window joints that has cracked
- Failed mastic on an exposed elevation
- Crumbling sand mastic round a window
If you let a flat or house near Sittingbourne station, older sash windows in a rental need their mastic kept sound to keep the weather out.

Common questions in Bredgar
Will you come out to Bredgar?
Yes. Bredgar is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for landlords with property near Sittingbourne station?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or email us and tell us about the property, and we will give you a clear price.
What sealant do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Will the old sealant be removed?
Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access.
What does sand mastic cost?
Every job is different, so each one gets its own quote. To get one, ring 0345 464 0079 or send us an email with a short description of the job.
What information do you need?
Only a few details: where it is, what you’ve noticed and how we reach it. Then call 0345 464 0079 or email us.
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Plan mastic work ahead of painting
- Take care around the mastic when scraping paint
- Ask a joiner to look at soft timber first
- Ask us before painting near the mastic
Leave the new mastic alone while it firms up. It forms a skin fairly soon, but takes longer to harden fully.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.
How it works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a single window, longer for several, and the area is left clean. Somewhere like Bredgar needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
How to prepare
- Mention if the joints have been sealed before
- Keep children and pets away from the work area
- Mention any tricky access

Advice
Sand mastic in Bredgar: local notes
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Schools such as Bredgar Church of England Primary School are buildings too, and 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 John the Baptist, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
