About our sand mastic in Hadlow Down
Fresh sand mastic forms a skin quite soon, but it takes longer to harden fully. Traditionally, sand mastic is left unpainted, so ask us before you decorate. Typical jobs include a silicone bead on a sash window that spoils the look and weathered mastic on the most exposed windows, across brick reveals, period & listed homes and timber door frames.
Around Hadlow Down, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
Each job carries a 12-month guarantee, whatever its size.

What sand mastic looks like in Hadlow Down
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to St Mark's Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you let a flat or house near Buxted station, any sash windows need sound mastic to keep draughts and rain out.

What affects the quote in Hadlow Down
Jobs vary more than people expect. The main factors:
- Whether the work is at height
- Working hours on commercial sites
- Whether old sealant or filler has to be cut out
- The number of rooms or windows
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

For landlords and businesses
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 that we can handle for you.
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
Do you need sand mastic in Hadlow Down?
Shallow joints are a common cause. Mastic that’s too thin cracks and drops out, which is why we pack deep voids first and get the depth right.
Most people get in touch when they notice something like this:
- Window mastic to renew ahead of painting
- Patchy fillers round a sash window
- Mastic round period door frames that has failed
- Silicone on a period window that looks wrong
Schools such as St Mark's Church of England Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

- Whether all the old sealant comes out first
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
