What we do, step by step
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for a single window, longer for several. In a smaller place like Bearsted, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We check the window surrounds and agree which joints need renewing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The mastic is finished to sit tidily against the stone or brick.
Before we arrive
- Let us know about earlier repairs to the joints
- Mention any sign-in or site rules at work premises
- Tell us about access, such as stairs, a lift or high-level joints

Advice
Sand mastic for homes and businesses in Bearsted
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 sash and case windows, tenement windows and period & listed homes, and people most often call us about draughts and rain around sash boxes and patchy fillers round a sash window.
In smaller places like Bearsted, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. Each frame material needs the right sealant against the right wall.
You’re covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
Leave it or put it right?
Not every draught comes from the sashes themselves. Open mastic joints round the box can let air in and new mastic seals them. Around Bearsted, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

Most of the time, yes. We’ll tell you which colours the right product comes in and agree one before any work starts.
Can you replace silicone on a period window with sand mastic?

Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.

What sand mastic looks like in Bearsted
With historic houses such as Stoneacre (about 1.3 miles south) nearby, there’s older building stock in the area around Bearsted as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homes close to Holy Cross Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For site and facilities teams at buildings such as Thurnham Church of England Infant School, larger buildings have plenty of frames, and the mastic around each one ages.

Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Sort the mastic before the decorators arrive
- Ask the planning authority about consent for listed or conservation-area homes
- Do not run silicone over sand mastic
- Ask us before painting near the mastic
Don’t run silicone over the new mastic. If anything cracks, get it looked at before trying a quick fix.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.
