Palmarsh Sand Mastic
We cover Palmarsh for traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.

Sand mastic in Palmarsh
Fresh sand mastic forms a skin quite soon but full hardening takes longer. Traditional guidance is not to paint over it, so ask us before you decorate. Typical jobs include gaps round a timber door in stone or brick and gaps between timber frames and stone or brick, on stone surrounds, tenement windows and brick reveals.
In a smaller place like Palmarsh, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. The mastic around frames on those walls tends to age faster.
Big or small, you get the same 12-month guarantee in Palmarsh and across Kent.

What we do, step by step
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes a few hours for a single window, longer for several, depending on how much there is to do. For a job in Palmarsh, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First, we look at the surrounds with you and agree what needs doing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Getting ready for the visit
- Let us know about parking restrictions
- Mention any leaks or damp you’ve noticed
- For indoor joints, keep the area dry beforehand if you can

Related advice
Do you need sand mastic in Palmarsh?
Over the years, sand mastic weathers. It dries out, cracks and loses its grip on the stone or timber.
Most people get in touch after spotting something like this:
- Silicone on a period window that looks wrong
- Tired mastic found when preparing windows for paint
- Mastic round period door frames that has failed
- Gaps between timber frames and stone or brick
Rented homes near Sandling station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.
What your quote should include
- Is the old sealant removed completely?
- What happens if the job turns out different
- How the surfaces are prepared before sealing
- The length of the guarantee
Why it’s worth doing now in Palmarsh
New sash windows are a major, costly change and on a listed home, consent may be needed. Where the frames are in good order, new mastic seals the surround. In a smaller place like Palmarsh, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we will go through it with you.

FAQs for Palmarsh
Do you work for landlords with property near Sandling station?
Yes, we work for landlords and agents. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before we start.
Is Palmarsh within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
What information do you need?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Where are you based?
We work from Crawley. Our applicators cover Palmarsh, along with the rest of our area.
Which is right for my windows, sand mastic or modern sealant?
We will talk it through with you. Period homes often look best with sand mastic and newer frames suit modern sealant.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us and we are fully insured.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Will the old sealant be removed?
Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.
Windows and doors in Palmarsh
Palmarsh 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. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For site and facilities teams at buildings such as Palmarsh Primary School, larger buildings have plenty of frames, and the mastic around each one ages. For an older house near a landmark such as Holy Cross, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Aftercare tips
How long the joints last depends on use and care. We suggest:
- Keep sills and gutters clear so water drains away
- Find out about consent before window work on a listed home
- Have rotten timber repaired before new mastic goes in
- Don’t run silicone over sand mastic
Leave the new mastic unpainted, as traditional guidance advises. If you’re redecorating, ask us first.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber, which can lead to rot.
DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
