Sand mastic for homes and businesses in Mislingford
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s made from sand and a linseed-oil-based binder, applied by hand. On period homes, it looks right where silicone wouldn’t. We work on stone surrounds, tenement windows and sash and case windows, and the jobs we see most are modern sealant on a period surround and crumbling sand mastic round a window.
Somewhere as small as Mislingford, 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.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

DIY versus a professional finish
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Common problems we fix in Mislingford
Rain on the window surround works into any crack and loosens it further. Exposed elevations normally fail first.
These are the problems we’re asked about most:
- Open joints round the window box
- Modern sealant on a period surround
- Cement or filler used on old window joints that has cracked
- Mastic that needs renewing before redecorating
If you look after a building such as Swanmore College of Technology, its window and door frames need their mastic kept sound, just like a home’s.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Do not run silicone over sand mastic
- Get any rot dealt with first
- Take care around the mastic when scraping paint
- Do not paint over the new mastic
Make sure water drains away from the window surround. Constant wetting wears the mastic faster.
An open joint round the box lets weather through. Left, the gap tends to get bigger.
Common questions in Mislingford
Do you work for landlords with property near Botley station?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we will send you a clear quote.
Do you cover Mislingford for sand mastic?
Yes, Mislingford is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear price.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that generally means someone at home.
Is it possible to paint over sand mastic?
Sand mastic is normally left unpainted, as guidance on traditional windows advises. Ask us before decorating.
Is the work guaranteed?
Every job comes with our one-year guarantee, and we’re fully insured.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Will it make a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Where do you work from?
We are a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
What happens if it’s left?
If you are redecorating, renew the mastic first. Paint over cracked mastic will not stop the gaps, and the new mastic is traditionally left unpainted. Older cottages and farmhouses around Mislingford can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before any work starts.
