Sand mastic for homes and businesses in Little Mill
Burnt sand mastic is a traditional material blends with stone and brick surrounds. It suits period and listed homes where a modern sealant bead would stand out. We work on period & listed homes, tenement windows and stone surrounds, and people most often call us about mastic dropping out of the joint and old cement repairs round a window that have failed.
In a village or hamlet like Little Mill, 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.
The work is covered for a year after we finish. If anything is not right with it, ring 0345 464 0079 or send us an email.

How the visit works
There is not much for you to do on the day. Show us the job and we will take it from there. The work itself takes a few hours for a single window, longer for several. For a village or hamlet like Little Mill, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by checking each surround and agreeing the joints to renew.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.
Preparing for the visit
- Mention if the joints have been sealed before
- Let us know if you’ve seen damp or leaks
- Plan for the work area to be out of bounds to pets and children

How to look after the new joints
Good habits help new joints last longer. A few tips:
- Take care around the mastic when scraping paint
- Have rotten timber repaired before new mastic goes in
- Ask the planning authority about consent for listed or conservation-area homes
- Plan mastic work ahead of painting
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.
How the job changes by surface
Tenement and terrace windows
In shared buildings, the windows may be part of a wider repair, so check who is responsible first.
Timber door frames
Sand mastic is used round timber door frames too. The method is the same as for windows.
Do you need sand mastic in Little Mill?
Age is the main cause. Sand mastic is a maintenance item like any pointing, depending on exposure and upkeep.
Signs it’s time to call us include:
- Draughty sash windows at the surround
- Old sand mastic that has cracked, crumbled or fallen out
- Old cement repairs round a window that have failed
- Silicone on a period window that looks wrong
Schools such as East Peckham Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

What sand mastic looks like in Little Mill
Historic houses like Old Soar Manor (about 4.4 miles north-west) are a reminder that the area around Little Mill has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around Church of the Holy Trinity, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Rented homes near Beltring station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.

Which products do you use?

Is consent needed for window work on a listed home?
It’s best to ask your local planning authority first. Sand mastic is often favoured as like for like but the decision is theirs.
How long will you be here?
As a guide, most jobs take a few hours per window, depending on the condition of the joints. Bigger jobs take longer.
Can I paint the new mastic?
It’s traditionally left unpainted, as guidance on traditional windows advises. Ask us before decorating.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
