Aftercare tips
Good habits help new joints last longer. Our tips:
- Avoid heavy scraping on the mastic joint
- Ask us before painting near the mastic
- Ask a joiner to look at soft timber first
- Avoid patching sand mastic with silicone
Don’t touch or press the mastic while it hardens. It skins over quickly, but takes longer to harden fully.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.
Sand mastic in Brabourne, done properly
Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. Renewing it closes the gap so the surround looks right again. We work on timber door frames, sash and case windows and brick reveals, and the jobs we see most are gaps between timber frames and stone or brick and draughts and rain around sash boxes.
Outdoor sealant needs dry, clean surfaces, so work on frames around Brabourne is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
Big or small, you get the same 12-month guarantee in Brabourne and across Kent.

Leave it or put it right?
Not every filler suits an old window surround. Sand mastic is the like-for-like choice, which can matter on listed and conservation-area homes. In a small place like Brabourne, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or drop us an email and we’ll talk you through it.

Sand mastic in Brabourne: 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. With historic houses such as Westenhanger Castle (about 3.3 miles south-east) nearby, there’s older building stock in the area around Brabourne as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Schools such as Brabourne Church of England Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. If you live in an older home near Church of St Mary, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

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.

There can be a smell while the sealant cures. Ventilation helps.
