Sand mastic for sash & case windows in Moorstock, Kent
Professional sand mastic in and around Moorstock, with every bit of old sealant taken out first.
- Silicone on a period window that looks wrong
- Old sand mastic that has cracked, crumbled or fallen out
- Mastic worn away on windows facing the weather
How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Renew mastic before redecorating the windows
- Keep sills and gutters clear so water drains away
- Ask the planning authority about consent for listed or conservation-area homes
- Inspect the joints round the windows every year or so
Leave the new mastic unpainted, which is the traditional advice. If you’re redecorating, ask us first.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.
About our sand mastic in Moorstock
If your home is listed or in a conservation area, check with your local planning authority if consent is needed before window work. Like-for-like sand mastic is often the preferred finish. Common call-outs are for gaps round a timber door in stone or brick and failed mastic on an exposed elevation, on brick reveals, period & listed homes and tenement windows.
Around Moorstock, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
Each job carries a 12-month guarantee, large or small.

Honest limits
New sealant cannot fix everything, and we’d rather say so up front. It won’t solve:
- Rotten sashes, sills or window boxes (a joiner’s job)
- Putty and glazing repairs
- Whether work needs listed building consent
If in doubt, ring 0345 464 0079 or email us and we’ll say what we think before booking.
What we seal
- Stone surrounds
- Sash and case windows
- Period & listed homes
- Timber door frames
- Tenement windows
- Brick reveals
What we are called out for in Moorstock
Rain on the window surround works into any crack and loosens it further. Windows facing the weather tend to go first.
The most common problems we see are:
- Mastic dropping out of the joint
- Tired mastic found when preparing windows for paint
- A silicone bead on a sash window that spoils the look
- Patchy fillers round a sash window
If you live in an older home near Church of St Mary, the joint between an old wall and a newer frame is normally the first place rain gets in.

Surface by surface
Timber door frames
A neat sand mastic joint round a front door suits a period home.
Stone surrounds
Old stone surrounds are often uneven, so the gap is not the same all the way round. We shape it by hand to follow the stone.
The process
There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The work itself takes a few hours per window, depending on the condition of the joints, including the tidy-up. For a village or hamlet like Moorstock, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.
How to prepare
- For business premises, tell us about site rules or sign-in
- Let us know about earlier repairs to the joints
- Where the joints are inside, avoid wetting them before we arrive

Windows and doors in Moorstock
With historic houses such as Westenhanger Castle (about 1.6 miles south-east) nearby, there’s older building stock in the area around Moorstock as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. 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.
Managing a site like Sellindge Primary School? Then the mastic around its windows and doors needs looking after like any other building’s. Letting a property close to Westenhanger station? Then older sash windows in a rental need their mastic kept sound to keep the weather out.

Around Moorstock

Why act early in Moorstock
Draughts round a sash window aren’t always the sashes. Open mastic joints round the box can let air in, and renewing the mastic closes them. In a small place like Moorstock, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.
