Sand mastic in Hankham
Sand mastic skins over fairly quickly but full hardening takes longer. Traditional guidance is not to paint over it, so ask us before you decorate. If you have mastic dropping out of the joint and gaps between timber frames and stone or brick, we can put it right, on period & listed homes, stone surrounds and brick reveals alike.
Around Hankham, 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.
All of our work is guaranteed for twelve months, in Hankham and everywhere else we cover.

Sand mastic in Hankham: local notes
Hankham is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In the older streets around St Luke's Church, the joint between an old wall and a newer frame is normally the first place rain gets in. Rented homes near Pevensey & Westham station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.

If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each surround is checked first.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic isn’t too thick.

What else we do in Hankham
Hankham: your questions answered
Do you work for landlords with property near Pevensey & Westham station?
Yes, we work for landlords and letting agents. Just ring 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.
Does the coastal weather in Hankham affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Can old silicone round a sash window be swapped for sand mastic?
Generally, yes. Once the silicone is out and the joint prepared we point it with sand mastic.
What exactly is sand mastic?
It’s sand mixed with a linseed-oil-based binder, used between timber frames and stone or brick.
Are you insured?
Yes. We are fully insured, with over 20 years’ experience in sealant work.
What sealant do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll explain our choice.
Is there any odour?
There can be a smell while the sealant cures. Ventilation helps.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is normally more efficient.

Housing providers, facilities teams and property managers book us too in Hankham and across East Sussex. We can quote a run of properties together, and we’re fully insured.

What we are called out for in Hankham
Sand mastic slowly weathers. It dries out, cracks and loses its grip from the frame or the masonry.
Common reasons people contact us include:
- A silicone bead on a sash window that spoils the look
- Mastic worn away on windows facing the weather
- Mastic that needs renewing before redecorating
- Wind and rain getting in round a sash window
If you look after a building such as Hankham Primary School, its window and door frames need their mastic kept sound, just like a home’s.
Questions to ask before booking
- Whether they’re fully insured
- Whether you can choose the colour
- What product goes in the joint
- Is the old sealant removed completely?
Why act early in Hankham
Draughts round a sash window aren’t always the sashes. Gaps between the frame and the wall can be just as bad and new mastic seals them. In a small place like Hankham, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part.
Why us?
- We leave the area clean and tidy
- Sanitary silicone with an anti-fungal additive in wet areas
- Full insurance on every job
- One-year guarantee on every job

What sealant work can’t fix
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- Sash cords, weights and draught-proofing of the sashes
- Broken panes
- Decayed frames that need repair
If you’re not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer.
