Sand mastic in Mount Bures, done properly
Across Mount Bures, we renew sand mastic around sash and case windows. Every joint is cleaned out and filled by hand for a neat, traditional finish. We work on tenement windows, timber door frames and brick reveals, and common reasons people get in touch are gaps where the frame meets the masonry and mastic worn away on windows facing the weather.
In a village or hamlet like Mount Bures, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
Your job is guaranteed for a year, as with all our work.

Advice
Why act early in Mount Bures
If you’re redecorating, renew the mastic first. Painting over failed mastic doesn’t seal it, and the new mastic is traditionally left unpainted. Older cottages and farmhouses around Mount Bures can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on the amount of work, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts.
Why us?
- We never seal over old sealant
- 20+ years of sealant experience
- Tidy, careful work
- Full insurance on every job

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Ask us before painting near the mastic
- Plan mastic work ahead of painting
- Get any rot dealt with first
- Clear gutters so water does not pour onto the windows
Leave the new mastic alone while it firms up. It forms a skin fairly soon, but takes longer to harden fully.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
Questions from Mount Bures
Is Mount Bures in your area for sand mastic?
Yes. Our work covers London and the South East, and Mount Bures is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear quote.
Do you cover smaller places like Mount Bures?
Yes, Mount Bures is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Are you fully insured?
Yes. We are fully insured, and we have been doing sealant work for more than 20 years.
Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Can you replace silicone on a period window with sand mastic?
Yes, it’s a common request. The old silicone has to come out completely so the mastic can sit properly.
What exactly is sand mastic?
Sand mastic is a traditional material for pointing round windows and doors. It’s made with sand and a linseed-oil-based binder.
Where are you based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.

We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
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, and the work is guaranteed for a year.
