About our sand mastic in Pleshey
On many period windows, sand mastic looks right and suits the building. On modern frames we’d normally use a flexible sealant, and we’ll talk through which suits your home. If you have modern sealant on a period surround and old sand mastic that has cracked, crumbled or fallen out, we can help, on stone surrounds, brick reveals and timber door frames alike.
Homes in small places like Pleshey often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
All our work comes with our 12-month guarantee.

Frames and glazing around Pleshey
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Around Pleshey, as everywhere, sand mastic is only as good as the preparation behind it. If you live in an older home near Church of Holy Trinity, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

How it works
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take anything from a few hours to a full day, depending on how many windows. Somewhere as small as Pleshey, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic isn’t too thick.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
Preparing for the visit
- Tell us about any water getting in
- Clear items away from the joints we’re working on
- Mention any tricky access

Related advice
DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Why it’s worth doing now in Pleshey
Replacing sash windows is a big decision for a period home, and in listed buildings it may need consent. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Where a wall is exposed, as many are in small places like Pleshey, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Combining jobs into one visit is normally more efficient than separate visits. We’ll give you a clear quote for the lot.

Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Check with your local planning authority if your home is listed
- Keep sills and gutters clear so water drains away
- Look over the window mastic once a year
- Go gently near the mastic when preparing windows
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
