About our sand mastic in Brighton and Hove
For a listed home or one in a conservation area, ask your local planning authority if consent is needed before window work. Sand mastic is often favoured as a like-for-like material. We work on period & listed homes, tenement windows and stone surrounds, and the jobs we see most are window mastic to renew ahead of painting and a silicone bead on a sash window that spoils the look.
Plenty of homes in a town like Brighton and Hove have had conservatories, patio doors or new windows added over the years. Every addition brings more joints, each wearing at its own pace. Leaks normally start at a sill, a frame head or a glazing joint.
The work is covered for a year after we finish. If anything isn’t right with it, ring 0345 464 0079 or drop us an email.

Surface by surface
Period and listed homes
Many older homes were built with sand mastic round the windows. If your home is listed, ask your local planning authority about consent.
Timber door frames
Round a period front door, sand mastic gives the right look.
Looking after it afterwards
After the cure time, these simple habits help:
- Ask us before painting near the mastic
- Don’t run silicone over sand mastic
- Inspect the joints round the windows every year or so
- Check with your local planning authority if your home is listed
When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.
Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger.
Sand mastic in Brighton and Hove: local notes
Brighton and Hove is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. With historic houses such as Portslade Manor (about 1.3 miles west) nearby, there’s older building stock in the area around Brighton and Hove as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Managing a site like West Hove Infant School? Then larger buildings have plenty of frames, and the mastic around each one ages. For landlords with property near Aldrington station, any sash windows need sound mastic to keep draughts and rain out.

How the visit works
We keep the work tidy and contained to the joints we’re treating, so you can carry on as normal. Expect the work to take a few hours for a single window, longer for several, and we tell you how long to leave it before we go. In Brighton and Hove, parking is rarely complicated, though it helps to know about driveways or restrictions, and mention if the work is upstairs, in a flat or high on the outside.
- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
How to prepare
- Mention any tricky access
- Keep pets and children clear of the area while we work
- Let us know about parking restrictions

Brighton and Hove: your questions answered
Do you work for landlords with property near Aldrington station?
Yes, we work for landlords and agents. You can call 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Does living near the coast affect sand mastic in Brighton and Hove?
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 normally the first to need attention.
What’s sand mastic made of?
A traditional pointing material made from sand and a linseed-oil-based binder for the joint between timber frames and masonry.
What information do you need?
Tell us what needs doing and where, plus pictures if you have them. We will ask anything else we need to know.
Is consent needed for window work on a listed home?
Your local planning authority is the one to ask. They’ll tell you if consent is needed.
Can you do several jobs on one visit?
Yes. Several rooms, windows or areas can go on one quote.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Are you insured?
Yes. We’re fully insured, with over 20 years’ experience in sealant work.
What we are called out for in Brighton and Hove
Rain on the window surround works into any crack and pushes it out. Windows facing the weather tend to go first.
Look out for these signs:
- Mastic that needs renewing before redecorating
- Gaps where the frame meets the masonry
- Failed mastic on an exposed elevation
- Draughty sash windows at the surround
In the older streets around Holy Cross Church, the joint between an old wall and a newer frame is usually the first place rain gets in.
