Sand mastic for homes and businesses in Tarpots
Traditional burnt sand mastic blends with stone and brick surrounds. It’s a good fit for period properties, where modern sealant can look out of place. We work on tenement windows, timber door frames and sash and case windows, and common reasons people get in touch are tired mastic found when preparing windows for paint and gaps between timber frames and stone or brick.
Around Tarpots, 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.
Big or small, it’s backed by our one-year guarantee in Tarpots and across Essex.

How to look after the new joints
A little care helps the new joints last. Our advice:
- Check the mastic when you check the paintwork
- Make sure water runs off the sill
- Leave the new mastic unpainted
- Find out about consent before window work on a listed home
Leave the new mastic unpainted, which is the traditional advice. Ask us before any decorating around it.
Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger as more mastic falls out.

Leave it or put it right?
Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic suits the building and finishes neatly against the masonry. Older cottages and farmhouses around Tarpots can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and give you a clear quote before work begins.

Can I do it myself?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
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.

Common problems we fix in Tarpots
Decorating can disturb tired mastic. It’s often found when windows are being prepared for paint, which is a good time to renew it.
If you can see any of these, it’s time to have the joints looked at:
- Failed mastic on an exposed elevation
- Wind and rain getting in round a sash window
- Crumbling sand mastic round a window
- Gaps round a timber door in stone or brick
For an older house near a landmark such as St George, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

- How the joint is cleaned and prepared

How it works
On the day, we start by going over the job with you, so you know exactly what we are doing. We protect the surfaces around the joints before work begins. Most jobs take a few hours per window, depending on the condition of the joints. For a village or hamlet like Tarpots, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We check the window surrounds and agree which joints need renewing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- For business premises, tell us about site rules or sign-in
- Move anything stored near the joints

What sand mastic looks like in Tarpots
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For site and facilities teams at buildings such as The Appleton School, the mastic around its windows and doors needs looking after like any other building’s. Letting a property close to Benfleet station? Then older sash windows in a rental need their mastic kept sound to keep the weather out.
