Sand mastic for homes and businesses in Badlesmere
We renew sand mastic around sash windows and doors in stone and brick. The old mastic is raked out, the joint is prepared and new mastic is shaped by hand. We work on stone surrounds, brick reveals and tenement windows, and common reasons people get in touch are mastic round period door frames that has failed and draughts and rain around sash boxes.
In a village or hamlet like Badlesmere, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

How we quote for sand mastic
We don’t publish a price list. The quote depends on:
- Whether the work is at height
- Whether old sealant or filler has to be cut out
- The size of the job
- Working hours on commercial sites
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part.
What we need to know
Before you ask for a quote, have a think about:
- Where the job is, and your postcode
- Access, such as stairs, a lift or height
- The problem you’ve noticed
- Whether it’s a home or a business
To get a quote, ring 0345 464 0079 or email us with the location and a short description of the problem. You will have a clear quote before any work starts.
How the job changes by surface
Stone surrounds
Stone openings are rarely perfectly straight, so the joint varies in width. We shape it by hand to follow the stone.
Timber door frames
A neat sand mastic joint round a front door suits a period home.
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Ask a joiner to look at soft timber first
- Clear gutters so water does not pour onto the windows
- Inspect the joints round the windows every year or so
- Leave the new mastic unpainted
Do not touch or press the mastic while it hardens. It forms a skin fairly soon, but takes longer to harden fully.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
Sand mastic in Badlesmere: local notes
With historic houses such as Belmont House and Gardens (about 1.9 miles north-west) nearby, there’s older building stock in the area around Badlesmere as well as newer homes. Where a home is older, 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, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Rented homes near Selling station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about. Schools such as Sheldwich Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. Homes close to Church of St Leonard include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What is sand mastic?
A traditional pointing material made from sand and a linseed-oil-based binder for the joint between timber frames and masonry.
How long does sand mastic take?
Typically it takes a few hours per window, depending on the condition of the joints. Larger jobs naturally take longer.
Should I check with the council before work on a listed or conservation-area home?
Check with your local planning authority. They’ll tell you if consent is needed.
Can I do it myself?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
What happens on the day
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and tidy away. It normally takes a few hours per window, depending on the condition of the joints. Somewhere as small as Badlesmere, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Mention any tricky access
- Tell us if parking is tricky

Why it’s worth doing now in Badlesmere
Silicone might seem the quicker option, but it can look wrong on a period surround. Sand mastic suits the building and finishes neatly against the masonry. Where a wall is exposed, as many are in small places like Badlesmere, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
What you pay reflects the work, not guesswork. That is why we ask a few questions first and agree the price before starting.
