Advice
Sand mastic for homes and businesses in Great Braxted
A silicone bead around a sash window can look out of place and doesn’t suit the building. Sand mastic is the traditional choice, and we can replace one with the other. Common call-outs are for mastic worn away on windows facing the weather and crumbling sand mastic round a window, on sash and case windows, timber door frames and brick reveals.
Homes in small places like Great Braxted often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
The work is covered for a year after we finish. If anything is not right with it, call 0345 464 0079 or send us an email.

Keeping the joints in good condition
After the cure time, these simple habits help:
- Check the mastic when you check the paintwork
- Keep sills and gutters clear so water drains away
- Take care around the mastic when scraping paint
- Keep modern sealant off the mastic
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens as more mastic falls out.
What sealant work can’t fix
In fairness, some problems need a different trade:
- Decisions on consent for listed homes
- Putty and glazing repairs
- Crumbling stone or brickwork round the window

Great Braxted: your questions answered
I let a flat near Witham station. Can you help?
Yes. We work for landlords and agents as well as homeowners. Just phone 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear quote.
Do you cover Great Braxted for sand mastic?
Yes, Great Braxted is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll give you a clear quote.
Is it OK to seal over old sealant?
No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Can sand mastic be painted?
Sand mastic is normally left unpainted, which is what traditional guidance recommends. Talk to us before any painting near it.
How long does sand mastic take to go off?
A skin forms quite soon, but full hardening takes longer. We’ll tell you what to expect for your job.
Are you insured?
Yes. We’re fully insured.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Windows and doors in Great Braxted
Historic houses like Layer Marney Tower (about 4.7 miles north-east) are a reminder that the area around Great Braxted 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, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Common problems we fix in Great Braxted
Paint, silicone or cement used over old mastic causes problems. They don’t suit the joint, and they normally need raking out.
These are the problems we’re asked about most:
- Tired mastic found when preparing windows for paint
- Cement or filler used on old window joints that has cracked
- Gaps round a timber door in stone or brick
- Draughty sash windows at the surround
If you live in an older home near Church of All Saints, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What affects the cost of sand mastic
We do not publish a price list, because jobs vary so much. What we look at:
- Whether old sealant or filler has to be cut out
- How many areas need sealing
- Whether the work is at height
- Which sealant suits the joint
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we will explain what it covers.
What to tell us for a quote
There’s no need for technical detail. Just tell us:
- Any access issues, like height or stairs
- Roughly how big the job is
- Any previous sealing or DIY work
- The problem you’ve noticed
It all starts with a short chat. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. When it suits you, call 0345 464 0079 or email us.
Why deal with it now?
New mastic over crumbling mastic won’t hold. We remove the loose material first so the new work lasts. Around Great Braxted, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.
