DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
About our sand mastic in Speldhurst
Burnt sand mastic is a traditional material that sits naturally against stone and brick. It suits period and listed homes, where modern sealant can look out of place. If you are dealing with window mastic to renew ahead of painting and gaps where the frame meets the masonry, we can put it right, on period & listed homes, sash and case windows and brick reveals alike.
Around Speldhurst, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
Whatever the size of the job, you get the same one-year guarantee.

What the job involves on each surface
Stone surrounds
Sand mastic sits naturally against stone. The finish blends with the masonry.
Period and listed homes
Sand mastic is the like-for-like choice for many period homes. If your home is listed, ask your local planning authority about consent.
What we do, step by step
There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the job takes a few hours for a single window, longer for several for a typical job. In a small place like Speldhurst, access is usually 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.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.
Preparing for the visit
- Move anything stored near the joints
- Keep pets and children clear of the area while we work
- Mention any sign-in or site rules at work premises

What does sand mastic cost?

Can old silicone round a sash window be swapped for sand mastic?

It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Which is right for my windows, sand mastic or modern sealant?
That depends on your windows. Period windows in stone or brick normally suit sand mastic, while modern frames normally get a flexible sealant.
Do you have insurance?
Yes. We are fully insured, and we can confirm the details when we quote.
What affects the quote in Speldhurst
The price is agreed before any work begins. It’s based on:
- Any mould that needs treating

- The number and length of the joints

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

Sand mastic in Speldhurst: local notes
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Penshurst Place (about 2.1 miles north-west) are a reminder that the area around Speldhurst 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.
If you live in an older home near Church of St Mary the Virgin, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For site and facilities teams at buildings such as Speldhurst Church of England Voluntary Aided Primary School, its window and door frames need their mastic kept sound, just like a home’s.
