Sand mastic for homes and businesses in Street End
Sand mastic skins over fairly quickly but full hardening takes longer. Traditional guidance is not to paint over it, so ask us before you decorate. If you are dealing with wind and rain getting in round a sash window and silicone on a period window that looks wrong, we can put it right, whatever the surface.
Around Street End, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

Why deal with it now?
Replacing sash windows is a big decision for a period home and on a listed home, consent may be needed. Where the frames are in good order, new mastic seals the surround. In a small place like Street End, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

Surface by surface
Timber door frames
Sand mastic is used round timber door frames too. We renew it the same way as on windows.
Stone surrounds
Stone openings are rarely perfectly straight, so the joint varies in width. Sand mastic is shaped by hand to suit.

How it works
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. Most jobs take anything from a few hours to a full day, depending on how many windows. For a village or hamlet like Street End, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- 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.
- The mastic is finished to sit tidily against the stone or brick.
How to prepare
- Mention any leaks or damp you’ve noticed
- Mention any tricky access
- Try not to wet indoor joints just before the visit

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Go gently near the mastic when preparing windows
- Keep sills and gutters clear so water drains away
- Inspect the joints round the windows every year or so
- Plan mastic work ahead of painting
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber, which can lead to rot.
What sand mastic looks like in Street End
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around Church of St Mary, the joint between an old wall and a newer frame is usually the first place rain gets in. Schools such as Simon Langton Grammar School for Boys are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
