About our sand mastic in Woolmer Hill
Traditional burnt sand mastic that sits naturally against stone and brick. It suits period and listed homes where a modern sealant bead would stand out. Common call-outs are for window mastic to renew ahead of painting and gaps where the frame meets the masonry, across sash and case windows, tenement windows and brick reveals.
Somewhere as small as Woolmer Hill, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
Each job carries a 12-month guarantee.

What happens on the day
There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the work takes a few hours for a single window, longer for several for a typical job. Somewhere like Woolmer Hill needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
Getting ready for the visit
- Move anything stored near the joints
- Tell us if parking is tricky

Woolmer Hill questions

Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
What’s sand mastic made of?
Sand plus a binder based on linseed oil. It’s applied by hand and shaped to suit the surround.
How long will you be here?
That depends on the amount of work, but as a guide it takes anything from a few hours to a full day, depending on how many windows. We’ll tell you when we quote.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.
Leave it or put it right?
Cement-based fillers and modern sealants don’t always suit a period surround. Sand mastic is the like-for-like choice, which can matter on listed and conservation-area homes. Where a wall is exposed, as many are in small places like Woolmer Hill, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first.

What we are called out for in Woolmer Hill
Some old mastic was never deep enough. Mastic that is too thin cracks and drops out, which is why we pack deep voids first and get the depth right.
If you can see any of these, it’s time to have the joints looked at:
- Gaps where the frame meets the masonry
- Wind and rain getting in round a sash window
- Tired mastic found when preparing windows for paint
- Silicone on a period window that looks wrong
Schools such as Camelsdale Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

When it isn’t the sealant
Some problems need a builder, plumber or other trade rather than us:

- Putty and glazing repairs
- Decisions on consent for listed homes

Windows and doors in Woolmer Hill
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For an older house near a landmark such as St Paul, the joint between an old wall and a newer frame is generally the first place rain gets in. If you let a flat or house near Haslemere station, any sash windows need sound mastic to keep draughts and rain out.

Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
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. Everything old must be removed first.
