Sand Mastic in Woolley Green
Our applicators work in Woolley Green on traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old sealant removed completely, joints prepared properly.

- Tired mastic found when preparing windows for paint
How we handle sand mastic in Woolley Green
If your home is listed or in a conservation area, check with your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. If you have cement or filler used on old window joints that has cracked and window mastic to renew ahead of painting, we can put it right.
Somewhere as small as Woolley Green, 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.
We stand behind the work with a one-year guarantee.

Sand mastic in Woolley Green: local notes
Historic houses like Harleyford Manor (about 3.3 miles north-west) are a reminder that the area around Woolley Green has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For an older house near a landmark such as Saint John the Evangelist, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Managing a site like Manor Green School? Then larger buildings have plenty of frames, and the mastic around each one ages.

Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Leave the new mastic unpainted
- Avoid patching sand mastic with silicone
- Clear gutters so water doesn’t pour onto the windows
- Check with your local planning authority if your home is listed
Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look before trying a quick fix.
An open joint round the box lets weather through. Left, the gap tends to get bigger.
How the job changes by surface
Timber door frames
Period doors in stone or brick openings are often pointed with sand mastic. The method is the same as for windows.
Brick reveals
Loose mastic comes out and deep gaps are packed before pointing.
Why it’s worth doing now in Woolley Green
A silicone bead can be quicker, but on period stone or brick it often looks out of place. Sand mastic is the traditional material and blends with the stone or brick. In a small place like Woolley Green, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.

Yes, Woolley Green is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or email us and let us know what needs doing.
Will you come out to Woolley Green?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you replace silicone on a period window with sand mastic?
Yes, we do this often. All the old silicone is removed first so the mastic beds in well.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
How do I get a quote for sand mastic in Woolley Green?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Is it possible to paint over sand mastic?
The usual advice is to leave sand mastic unpainted. If you’re redecorating the window, ask us first and we’ll talk you through it.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Is it OK to seal over old sealant?
No, because it fails. We remove every bit of old sealant first.
