Saltwood Sand Mastic
Sand mastic in Saltwood from a team with over 20 years’ experience. Rated 4.9 on Google from 180+ five-star reviews.
- Weathered mastic on the most exposed windows
- Gaps between timber frames and stone or brick
- A silicone bead on a sash window that spoils the look
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Sand mastic in Saltwood, done properly
Our applicators renew the sand mastic around sash and case windows and doors set in stone or brick. The old mastic is raked out, and new mastic is applied and shaped by hand. We are often asked to deal with mastic round period door frames that has failed and draughty sash windows at the surround, across period & listed homes, timber door frames and stone surrounds.
Homes in small places like Saltwood often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.

Saltwood questions
Do you cover smaller places like Saltwood?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Sandling station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Can new sealant go over the old?
No, it will not last. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
What information do you need?
A short description and the location. If we need more, we’ll ask.
Is it messy?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
How long does sand mastic take to go off?
It skins over fairly quickly but takes longer to harden fully. We will tell you what to expect for your job.
What sealant do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
When it is not the sealant
Before booking, it’s worth knowing the limits too:
- Rotten sashes, sills or window boxes (a joiner’s job)
- Sashes that need overhauling
- Crumbling stone or brickwork round the window
If you’re not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer before booking.

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Avoid patching sand mastic with silicone
- Ask us before painting near the mastic
- Check with your local planning authority if your home is listed
- Go gently near the mastic when preparing windows
When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall, so renewing it early is worth it.

Leave it or put it right?
Draughts round a sash window are not always the sashes. Gaps between the frame and the wall can be just as bad, and renewing the mastic closes them. Where a wall is exposed, as many are in small places like Saltwood, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first.

How the job changes by surface
Period and listed homes
On a listed home or in a conservation area, the right material matters. Sand mastic is often the preferred finish.
Timber door frames
A neat sand mastic joint round a front door suits a period home.
The process
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours per window, depending on the condition of the joints and we leave things clean and tidy. Somewhere as small as Saltwood, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each surround and agreeing the joints to renew.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- 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
- Mention any sign-in or site rules at work premises
- Mention if the joints have been sealed before
- Keep children and pets away from the work area

Advice
Saltwood homes and the weather
Saltwood is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Historic houses like Westenhanger Castle (about 2.2 miles north-west) are a reminder that the area around Saltwood has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
In the older streets around Church of St Peter and St Paul, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you look after a building such as Saltwood CofE Primary School, the mastic around its windows and doors needs looking after like any other building’s. Letting a property close to Sandling station? Then older sash windows in a rental need their mastic kept sound to keep the weather out.
