How we handle sand mastic in West Langdon
Sand mastic suits most period window surrounds. Newer frames normally get a flexible sealant instead, and we’ll talk through which suits your home. We work on tenement windows, sash and case windows and brick reveals, and people most often call us about gaps round a timber door in stone or brick and failed mastic on an exposed elevation.
In a village or hamlet like West Langdon, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
You get a one-year guarantee, the same in West Langdon as everywhere else we work.

What sand mastic looks like in West Langdon
Historic houses like Walmer Castle (about 3.9 miles north-east) are a reminder that the area around West Langdon has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
For an older house near a landmark such as St Mary the Virgin, the joint between an old wall and a newer frame is generally the first place rain gets in. Rented homes near Martin Mill station change hands often, and any sash windows need sound mastic to keep draughts and rain out.

What affects the cost of sand mastic
Every job gets its own quote. This is what makes a difference:
- How easy the joints are to reach
- Whether old sealant or filler has to be cut out
- Working hours on commercial sites
- How many areas need sealing
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins.
Asking for a quote
There’s no need for technical detail. Just tell us:
- Pictures of the joints, sent by email
- How many joints, rooms or windows are involved
- Where the job is, and your postcode
- If someone has resealed it before
Getting a quote is simple: let us know the job and the location. Photos by email help us understand the job, and we’ll come back to you with a quote.
DIY versus a professional finish
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

Leave it or put it right?
New mastic over crumbling mastic won’t hold. Raking out and preparing the joint gives it a sound base so the new work lasts. Older cottages and farmhouses around West Langdon can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll explain what it covers.

What is sand mastic?
It’s the traditional filler for the joint round timber windows and doors. It combines sand with a linseed-oil-based binder.
Where do you work from?
We are based in Crawley, and we work across South East England, London and Scotland.
Can I choose the sealant colour?
We will suggest a colour to suit the surroundings, from white and clear to greys and other shades. The product needed can limit the range.
Can you seal over the old sealant?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. It all has to come out first.

Common problems we fix in West Langdon
Over the years, sand mastic weathers. It hardens, cracks and starts to come away on the stone or timber.
The most common problems we see are:
- Gaps between timber frames and stone or brick
- Old sand mastic that has cracked, crumbled or fallen out
- Modern sealant on a period surround
- Tired mastic found when preparing windows for paint
Schools such as Langdon Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
