Sand mastic for homes and businesses in Hammerpot
Traditional burnt sand mastic that sits naturally against stone and brick. It’s a good fit for period properties, where modern sealant can look out of place. We are often asked to deal with window mastic to renew ahead of painting and patchy fillers round a sash window, on sash and case windows, tenement windows and timber door frames.
In a village or hamlet like Hammerpot, 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.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

FAQs for Hammerpot
Is sand mastic in a coastal place like Hammerpot any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are usually the first to need attention.
Can you help a landlord with a rental near Angmering station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just phone 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear price.
What exactly is sand mastic?
Sand plus a binder based on linseed oil. It’s applied by hand and shaped to suit the surround.
Is consent needed for window work on a listed home?
Speak to your local planning authority before work starts. Like-for-like sand mastic is often the preferred finish, but they decide.
How much does sand mastic cost in Hammerpot?

Which is right for my windows, sand mastic or modern sealant?

Aftercare tips
Aftercare is simple, and it makes a real difference:
- Do not run silicone over sand mastic
- Sort the mastic before the decorators arrive
- Clear gutters so water does not pour onto the windows
- Ask a joiner to look at soft timber first
Don’t run silicone over the new mastic. If you see a crack, ask us to take a look before trying a quick fix.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.

DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
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 does not work out, we can still put it right.
What we can’t put right
It helps to know what we can’t do:
- Damaged stone surrounds
- Cracked or broken glass
- Sashes that need overhauling
If you are not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer.

Frames and glazing around Hammerpot
Hammerpot is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around older windows and doors, especially on the side facing the sea. 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.
For an older house near a landmark such as The Parish Church of St Margaret, the joint between an old wall and a newer frame is generally the first place rain gets in. If you look after a building such as St Margaret's CofE Primary School, larger buildings have plenty of frames, and the mastic around each one ages. For landlords with property near Angmering station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

Leave it or put it right?
Gaps round a sash window let in rain and draughts. Water can get to the frame and the masonry so renewing it early protects the window. In a small place like Hammerpot, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
