How we handle sand mastic in Brattle
For a listed home or one in a conservation area, ask your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. If you have mastic dropping out of the joint and patchy fillers round a sash window, we can help, whatever the surface.
In a village or hamlet like Brattle, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
All of our work is guaranteed for twelve months.

Why it’s worth doing now in Brattle
New sash windows are a major, costly change, and in listed buildings it may need consent. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Around Brattle, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

What else we do in Brattle
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Leave the new mastic unpainted
- Go gently near the mastic when preparing windows
- Keep modern sealant off the mastic
- Have rotten timber repaired before new mastic goes in
Don’t touch or press the mastic while it hardens. It forms a skin fairly soon, but takes longer to harden fully.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.
When to call us in Brattle
Age is the main cause. Even well-laid mastic needs renewing in time, depending on exposure and upkeep.
If you can see any of these, it’s time to have the joints looked at:
- Cracked mastic round a front door frame
- Failed mastic on an exposed elevation
- Mastic that needs renewing before redecorating
- Silicone on a period window that looks wrong
For site and facilities teams at buildings such as Woodchurch Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Brattle questions
I let a flat near Appledore (Kent) station. Can you help?
Yes, we work for landlords and agents. Just call 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.
Is Brattle within the area you cover?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
What sealant do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
What information do you need?
Let us know what needs doing and where, with pictures by email if possible. If we need more, we will ask.
Can I paint the new mastic?
Sand mastic is normally left unpainted, which is what traditional guidance recommends. Ask us before decorating.
Do you have insurance?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Can you quote for more than one area?
Yes, we can. Several rooms, windows or areas can go on one quote.
What sand mastic looks like in Brattle
With historic houses such as Smallhythe Place (about 4.1 miles south-west) nearby, there’s older building stock in the area around Brattle as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you live in an older home near Parish Church of All Saints, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Rented homes near Appledore (Kent) station change hands often, and any sash windows need sound mastic to keep draughts and rain out.

DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
