How we handle sand mastic in Easton
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant and we’ll explain which is best for yours. Typical jobs include mastic dropping out of the joint and gaps round a timber door in stone or brick, on tenement windows, brick reveals and period & listed homes.
In a village or hamlet like Easton, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
You get a 12-month guarantee, the same in Easton as everywhere else we work.

Can I do it myself?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
What happens on the day
There isn’t much for you to do on the day. Show us the job and we’ll take it from there. The job generally takes anything from a few hours to a full day, depending on how many windows from start to finish. Somewhere as small as Easton, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic is not too thick.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
Before we arrive
- On commercial sites, let us know about site rules
- Mention any parking rules near the property
- Try not to wet indoor joints just before the visit

Why it’s worth doing now in Easton
A silicone bead can be quicker, but it can look wrong on a period surround. Sand mastic suits the building and blends with the stone or brick. Older cottages and farmhouses around Easton can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Why Easton clients choose us

What sand mastic looks like in Easton
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Benham Park (about 3.1 miles south-east) are a reminder that the area around Easton has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you live in an older home near Church of St Gregory, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Aftercare tips
Aftercare is simple:
- Have rotten timber repaired before new mastic goes in
- Make sure water runs off the sill
- Find out about consent before window work on a listed home
- Take care around the mastic when scraping paint
When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.
