How we handle sand mastic in Pevensey
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s a mix of sand and a linseed-oil-based binder and built up by hand. On older homes, it suits the building far better than silicone. We work on stone surrounds, tenement windows and period & listed homes, and the jobs we see most are mastic round period door frames that has failed and gaps between timber frames and stone or brick.
Outdoor sealant needs dry, clean surfaces, so work on frames around Pevensey is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
Every job comes with a one-year guarantee.

When it isn’t the sealant
We’d rather tell you now than do work that will not last, so these are the limits:
- Sash cords, weights and draught-proofing of the sashes
- Rotten sashes, sills or window boxes (a joiner’s job)
- Crumbling stone or brickwork round the window
If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before booking.
What we seal
- Timber door frames
- Stone surrounds

- Tenement windows
- Period & listed homes
- Sash and case windows
Why act early in Pevensey
New mastic over crumbling mastic won’t hold. We remove the loose material first so the new mastic stays put. Where a wall is exposed, as many are in small places like Pevensey, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

Frames and glazing around Pevensey
Pevensey is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around older windows and doors, especially on the side facing the sea. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Homes close to St. Nicolas Church include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in. Schools such as Pevensey and Westham CofE Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. For landlords with property near Pevensey Bay station, any sash windows need sound mastic to keep draughts and rain out.

Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
What we do, step by step
Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes anything from a few hours to a full day, depending on how many windows. Somewhere as small as Pevensey, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we look at the surrounds with you and agree what needs doing.
- Old, loose mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- Tell us if parking is tricky
- For indoor joints, keep the area dry beforehand if you can

Advice
Looking after it afterwards
A little care helps the new joints last. We recommend:
- Make sure water runs off the sill
- Don’t run silicone over sand mastic
- Go gently near the mastic when preparing windows
- Inspect the joints round the windows every year or so
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.

Common questions in Pevensey
Do you cover smaller places like Pevensey?
Yes. Pevensey is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is sand mastic in a coastal place like Pevensey any different?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. Walls facing the sea are normally the first to need attention.
Do I need permission for sand mastic on a listed building?
Checking first is sensible. Ask your local planning authority whether consent is needed for listed or conservation-area properties.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
How long does sand mastic take to go off?
It takes a while. It skins first and hardens fully later and we’ll give you an idea for your job.
Is it messy?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before resealing.
Do you do commercial work?
Yes. Larger jobs can be planned room by room or area by area to suit the site.
