Related advice
DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
If you’ve already had a go yourself, that is fine. We cut it out and start again.
Why deal with it now?
Not every filler suits an old window surround. Sand mastic matches what was there, which can matter on listed and conservation-area homes. Where a wall is exposed, as many are in small places like Hunters Forstal, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Doing several joints on one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear quote for the lot.

Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Check the mastic when you check the paintwork
- Go gently near the mastic when preparing windows
- Plan mastic work ahead of painting
- Keep sills and gutters clear so water drains away
Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.

Hunters Forstal: your questions answered
Do you cover smaller places like Hunters Forstal?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is sand mastic in a coastal place like Hunters Forstal any different?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are usually the first to need attention.
Do you remove the old sealant?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
How long does sand mastic take?
As a guide, most jobs take anything from a few hours to a full day, depending on how many windows. Larger jobs naturally take longer.
What guarantee comes with the work?
All our work has a one-year guarantee, and we’re fully insured.
Do you offer different sealant colours?
Usually, yes. Sealants come in white, clear, grey and other colours, and we agree the colour with you before we start.
Can sand mastic be painted?
It’s traditionally left unpainted, which is what traditional guidance recommends. Ask us before decorating.
Do I need to be at home?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you do not need to watch us work.
When it isn’t the sealant
We will always be straight with you, so here’s what sealant can’t fix:
- Sash cords, weights and draught-proofing of the sashes
- Whether work needs listed building consent
- Cracked or broken glass
If you’re not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer.

Sand mastic in Hunters Forstal: local notes
Hunters Forstal is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For landlords with property near Herne Bay station, older sash windows in a rental need their mastic kept sound to keep the weather out. Schools such as Herne Church of England Infant School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. Homes close to Church of St Bartholomew include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.
