Sand mastic for homes and businesses in Fingest
On many period windows, sand mastic looks right and suits the building. On modern frames we’d normally use a flexible sealant and we’ll explain which is best for yours. Typical jobs include gaps round a timber door in stone or brick and crumbling sand mastic round a window, across period & listed homes, brick reveals and timber door frames.
Homes in small places like Fingest 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.
A one-year guarantee comes as standard.

Fingest homes and the weather
Historic houses like Stonor Park (about 2.5 miles south-west) are a reminder that the area around Fingest 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. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homes close to Church of St Bartholomew include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Rented homes near Saunderton station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.

Can I do it myself?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What we can’t put right
We’d rather tell you now than do work that won’t last, so these are the limits:
- Crumbling stone or brickwork round the window
- Rotten sashes, sills or window boxes (a joiner’s job)
- Broken panes
If you are not sure, just call 0345 464 0079 or send us an email and we’ll give you a straight answer before you book.
Joints and surfaces we work on
- Sash and case windows
- Brick reveals
- Timber door frames
- Stone surrounds
- Tenement windows
- Period & listed homes
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Make sure water runs off the sill
- Avoid heavy scraping on the mastic joint
- Ask us before painting near the mastic
- Sort the mastic before the decorators arrive
Keep paint scrapers and sanders off the mastic when redecorating. It can be damaged by heavy scraping.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.

How it works

Everything for the job comes with us, so a second trip is avoided where possible.
