Sand mastic for homes and businesses in Fairbourne Heath
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s made from sand and a linseed-oil-based binder and built up by hand. On period homes, it looks right where silicone wouldn’t. We work on stone surrounds, sash and case windows and period & listed homes, and common reasons people get in touch are draughty sash windows at the surround and gaps between timber frames and stone or brick.
In a village or hamlet like Fairbourne Heath, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
Your job is guaranteed for a year, as with all our work.

Questions from Fairbourne Heath
Will you come out to Fairbourne Heath?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Harrietsham station?
Yes. We work for landlords and letting agents as well as householders, and several properties can be quoted together. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Where do you work from?
Our base is in Crawley, and we work across South East England, London and Scotland.
What does sand mastic cost?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before work begins.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Can you match the sealant colour?
Normally, yes. Sealants come in white, clear, grey and other colours, and we’ll agree it with you first.
How long does the job take?
Typically it takes a few hours per window, depending on the condition of the joints. Bigger jobs take longer, and we’ll tell you how long to expect.
Will the old sealant be removed?
Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.
Why act early in Fairbourne Heath
Replacing sash windows is a big decision for a period home 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 Fairbourne Heath, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.
What you get with us
- Quality sealants from Arbo and Everbuild
- Experience in homes, commercial sites and hotels

Advice
Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Keep modern sealant off the mastic
- Have rotten timber repaired before new mastic goes in
- Renew mastic before redecorating the windows
- Look over the window mastic once a year
Avoid sealing over the mastic with silicone. If anything cracks, get it looked at rather than patching it.
Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger.

Period and listed homes

Windows and doors in Fairbourne Heath
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. Historic houses like Leeds Castle (about 2.3 miles north-west) are a reminder that the area around Fairbourne Heath has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
In the older streets around All Saints Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you look after a building such as Platts Heath Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Should I try it myself first?

Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
