About our sand mastic in Ellesborough
We renew sand mastic around sash windows and doors in stone and brick. The old mastic is raked out, and new mastic is applied and shaped by hand. Typical jobs include old cement repairs round a window that have failed and mastic round period door frames that has failed, on sash and case windows, stone surrounds and brick reveals.
Somewhere as small as Ellesborough, older homes often have timber frames set in stone or brickwork. 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 Ellesborough as everywhere else we work.

What we do, step by step
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a single window, longer for several, and the area is left clean. Somewhere as small as Ellesborough, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check the window surrounds and agree which joints need renewing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- We dress the surface so it sits neatly against the masonry.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- For business premises, tell us about site rules or sign-in
- Where the joints are inside, avoid wetting them before we arrive

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
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. Everything old must be removed first.

Frames and glazing around Ellesborough
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For an older house near a landmark such as Church of St Peter and St Paul, the joint between an old wall and a newer frame is generally the first place rain gets in. Rented homes near Little Kimble station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. If you look after a building such as Great Kimble Church of England School, larger buildings have plenty of frames, and the mastic around each one ages.

Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we’ll quote.
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Keep modern sealant off the mastic
- Avoid heavy scraping on the mastic joint
- Do not paint over the new mastic
- Make sure water runs off the sill
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.
