About our sand mastic in Abberton
Our applicators renew the sand mastic around sash and case windows and doors set in stone or brick. The old mastic is raked out, the joint is prepared and new mastic is shaped by hand. Common call-outs are for silicone on a period window that looks wrong and crumbling sand mastic round a window, across sash and case windows, brick reveals and stone surrounds.
In a village or hamlet like Abberton, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
Big or small, it’s backed by our one-year guarantee in Abberton and across Essex.

How the visit works
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the job takes anything from a few hours to a full day, depending on how many windows in most cases. Somewhere like Abberton needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic isn’t too thick.
- 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.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Mention any tricky access
- Plan for the work area to be out of bounds to pets and children

Advice
Sand mastic in Abberton: local notes
Abberton is within about 3 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around older windows and doors, especially on the side facing the sea. 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.
If you look after a building such as Langenhoe Community Primary School and Pre-School, larger buildings have plenty of frames, and the mastic around each one ages. For landlords with property near Wivenhoe station, older sash windows in a rental need their mastic kept sound to keep the weather out.
Abberton is about 4 miles south of Colchester, in Essex. From the centre of Abberton to the outskirts, sand mastic is available for homes and businesses alike, from flats and houses to offices and hotels. Abberton is one of 644 towns and villages in Essex where we work for sand mastic. We also work in Chelmsford, around 19 miles away.

Local landmarks in Abberton
Locally, jobs take us to homes and businesses close to Thomas Lord Audley School and Language College and The Lion pub and the streets around them.

For a walk, there’s Roman River Valley.
Why it’s worth doing now in Abberton
New sash windows are a major, costly change and on a listed home, consent may be needed. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Where a wall is exposed, as many are in small places like Abberton, 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 is why we ask a few questions first.

What we are called out for in Abberton
Timber frames move with the seasons. The movement cracks the mastic little by little.
Common reasons people contact us include:
- Open joints round the window box
- Window mastic to renew ahead of painting
- Mastic worn away on windows facing the weather
- A silicone bead on a sash window that spoils the look
If you live in an older home near Church of St Andrew, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
What your quote should include
- Whether they’re fully insured
- How the joint is cleaned and prepared
- Is VAT in the price?
- What product goes in the joint
How the job changes by surface
Stone surrounds
Old stone surrounds are often uneven, so the joint varies in width. We shape it by hand to follow the stone.
Timber door frames
Period doors in stone or brick openings are often pointed with sand mastic. The method is the same as for windows.
When it isn’t the sealant
We will not take on work that will not last, so these are the limits:
- Crumbling stone or brickwork round the window
- Sashes that need overhauling
- Cracked or broken glass
Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly before booking.
What we seal

Abberton questions
Can you help a landlord with a rental near Wivenhoe station?
Yes. We work for landlords and agents as well as homeowners. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear price.
Is sand mastic in a coastal place like Abberton any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Can you seal over the old sealant?
No. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Should I try DIY first?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you do not need to watch us work.
What do you need from me for a quote?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply call 0345 464 0079 or email us.
When will the new mastic be hard?
Not straight away. The skin forms first, and the full set comes later and we will give you an idea for your job.
Are you insured?
Yes. We’re fully insured, and we have been doing sealant work for more than 20 years.
Can I do it myself?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
A careful DIYer can reseal a simple joint, 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.
