Landlords, agents and businesses in Chale Green
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
How we handle sand mastic in Chale Green
Sand mastic skins over fairly quickly but full hardening takes longer. Traditional guidance is not to paint over it and we will advise if you’re redecorating. We are often asked to deal with gaps round a timber door in stone or brick and window mastic to renew ahead of painting, across period & listed homes, brick reveals and stone surrounds.
In a village or hamlet like Chale Green, 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.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Why it’s worth doing now in Chale Green
Filling over old, loose mastic doesn’t last. Raking out and preparing the joint gives it a sound base so the new work lasts. Where a wall is exposed, as many are in small places like Chale Green, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and send you a clear quote before work begins.
Why book with us
- A 12-month guarantee on all work
- We never seal over old sealant

Windows and doors in Chale Green
Chale Green is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. 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.
In and around Chale Green, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint. If you live in an older home near St. James' Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Do you remove the old sealant?
Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.

Where are you based?

Is consent needed for window work on a listed home?
Your local planning authority is the one to ask. They decide whether consent is needed.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Do not paint over the new mastic
- Keep modern sealant off the mastic
- Plan mastic work ahead of painting
- Avoid heavy scraping on the mastic joint
Keep gutters and sills clear so water runs away from the surround. Water sitting against the mastic shortens its life.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber, which can lead to rot.
