Sand mastic for sash & case windows in Somerley, West Sussex
Sand mastic across Somerley and nearby, with old sealant always removed completely and a 12-month guarantee.
- Old cement repairs round a window that have failed
- Cracked mastic round a front door frame
- Mastic dropping out of the joint
Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Keep modern sealant off the mastic
- Get any rot dealt with first
- Do not paint over the new mastic
- Ask the planning authority about consent for listed or conservation-area homes
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
Sound mastic protects the frame. Once it fails, water can sit against the timber and timber that stays wet can rot.
About our sand mastic in Somerley
Sand mastic doesn’t last for ever, leaving gaps round the window. We rake it out and renew it and tidies the surround. We work on tenement windows, timber door frames and brick reveals, and people most often call us about a silicone bead on a sash window that spoils the look and gaps round a timber door in stone or brick.
Around Somerley, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
There’s a 12-month guarantee on every job, whatever its size.

What else we do in Somerley
Somerley homes and the weather
Somerley is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Rented homes near Fishbourne station change hands often, and any sash windows need sound mastic to keep draughts and rain out. In the older streets around St James' Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
Somerley is about 4 miles north-west of Selsey, in West Sussex. Homes, rented property, offices and hotels in Somerley can book us for sand mastic, old or new, large or small.

It’s worth asking for a quote if you see:
- Draughty sash windows at the surround

- Mastic worn away on windows facing the weather
If you look after a building such as Birdham CE Primary School, the mastic around its windows and doors needs looking after like any other building’s.

FAQs for Somerley
Do you cover smaller places like Somerley?
Yes, Somerley is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
I let a flat near Fishbourne station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can call 0345 464 0079 or email us with the details for a clear quote.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures.
Can I paint the new mastic?
Sand mastic is normally left unpainted, which is what traditional guidance recommends. Talk to us before any painting near it.
Is it OK to seal over old sealant?
No, it won’t last. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Are you ARBOMaster approved?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
How long does sand mastic take to harden?
It forms a skin fairly soon, then hardens over a longer period. Timing depends on the weather and the joint.
Which is right for my windows, sand mastic or modern sealant?
It depends on the window. Period windows in stone or brick normally suit sand mastic and newer frames usually get a flexible sealant.
When it isn’t the sealant
It helps to know what we cannot do too:
- Planning or listed building consent (your local planning authority decides)
- Putty and glazing repairs
- Sashes that need overhauling
