Sand mastic in Stoke
Traditional burnt sand mastic that sits naturally against stone and brick. It’s a good fit for period properties, where modern sealant can look out of place. We work on brick reveals, stone surrounds and timber door frames, and people most often call us about window mastic to renew ahead of painting and gaps round a timber door in stone or brick.
In a village or hamlet like Stoke, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Stoke homes and the weather
Stoke is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Historic houses like Warblington Castle (about 1.8 miles north) are a reminder that the area around Stoke has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
For an older house near a landmark such as Church of St Peter, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Rented homes near Warblington station change hands often, and any sash windows need sound mastic to keep draughts and rain out. If you look after a building such as The Hayling College, larger buildings have plenty of frames, and the mastic around each one ages.

How the job changes by surface
Sash and case windows
Most of our sand mastic work is on sash windows. We renew the mastic round each box.
Timber door frames
Sand mastic is used round timber door frames too. We renew it the same way as on windows.
Aftercare tips
So the new joints stay in good condition:
- Make sure water runs off the sill
- Inspect the joints round the windows every year or so
- Ask us before painting near the mastic
- Keep modern sealant off the mastic
Avoid painting over the new mastic, as traditional guidance advises. If you are redecorating, ask us first.
Once mastic starts to crumble, rain gets in. That water can reach the timber frame and the wall, so renewing it early is worth it.
How the visit works
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours for a single window, longer for several, and the area is left clean. In a small place like Stoke, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
How to prepare
- Let us know about stairs, lifts or work at height
- Tell us about any previous sealing or DIY attempts
- Mention any sign-in or site rules at work premises

Related advice
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Landlord and commercial work in Stoke
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will quote.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can be quoted together.
Your questions about sand mastic in Stoke
Does living near the coast affect sand mastic in Stoke?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Do you work for landlords with property near Warblington station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear quote.
What should I tell you?
Let us know what needs doing and where. If we need more, we’ll ask.
Can old silicone round a sash window be swapped for sand mastic?
Yes, we do this often. The old silicone has to come out completely so the mastic can sit properly.
Where is Mr Mastic based?
Our base is Crawley. Our area covers South East England, London and Scotland.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Do the sealants smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.

Asking for a quote

- Where the job is, and your postcode
