Sand mastic for homes and businesses in Caring
A silicone bead around a sash window can look out of place and doesn’t suit the building. Sand mastic is the traditional choice, and we can replace one with the other. If you are dealing with tired mastic found when preparing windows for paint and failed mastic on an exposed elevation, we can put it right.
Homes in small places like Caring 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.
You’re covered for a year from the day we finish. If anything is not right with it, call 0345 464 0079 or email us.

Signs you need sand mastic in Caring
Timber swells and shrinks with the weather. The movement cracks the mastic little by little.
Keep an eye out for any of the following:
- Mastic dropping out of the joint
- Open joints round the window box
- Tired mastic found when preparing windows for paint
- A silicone bead on a sash window that spoils the look
For an older house near a landmark such as St Nicholas's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
Letting agents and landlords in Caring can book us as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.

There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the job takes anything from a few hours to a full day, depending on how many windows in most cases. Somewhere like Caring needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

Caring questions
Is Caring within the area you cover?
Yes, Caring is covered. 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.
I let a flat near Bearsted station. Can you help?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before we start.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures.
What is sand mastic?
It’s sand mixed with a linseed-oil-based binder for the joint between timber frames and masonry.
Do I need to be at home?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
When will the new mastic be hard?
Not right away. The skin forms first, and the full set comes later and we’ll give you an idea for your job.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We’ll tell you what we’re using and why.
How do I get a quote for sand mastic in Caring?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.
Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Renew mastic before redecorating the windows
- Ask a joiner to look at soft timber first
- Clear gutters so water does not pour onto the windows
- Avoid patching sand mastic with silicone
When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
When something else is needed
It helps to know what we cannot do too:
- Sash cords, weights and draught-proofing of the sashes
- Putty and glazing repairs
- Decisions on consent for listed homes
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly before booking.

Why act early in Caring
Draughts round a sash window are not always the sashes. Gaps between the frame and the wall can be just as bad and new mastic seals them. In a small place like Caring, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

Caring homes and the weather
With historic houses such as Stoneacre (about 0.7 miles south-west) nearby, there’s older building stock in the area around Caring 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 is traditional sand mastic. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Letting a property close to Bearsted station? Then older sash windows in a rental need their mastic kept sound to keep the weather out. For site and facilities teams at buildings such as Leeds and Broomfield Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s.
