Brick reveals
An open joint at a brick reveal lets weather in. New mastic seals the gap.
Period and listed homes
On a listed home or in a conservation area, the right material matters. Like-for-like sand mastic is generally favoured.
Sand mastic in Brading, done properly
Across Brading, we renew sand mastic around sash and case windows. Each joint is raked out, prepared and pointed by hand for a neat, traditional finish. Typical jobs include cement or filler used on old window joints that has cracked and gaps between timber frames and stone or brick, across timber door frames, tenement windows and stone surrounds.
Around Brading, 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.
All our work is covered by a 12-month guarantee.

Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Go gently near the mastic when preparing windows
- Clear gutters so water doesn’t pour onto the windows
- Do not paint over the new mastic
- Get any rot dealt with first
Do not run silicone over the new mastic. If you see a crack, ask us to take a look before trying a quick fix.
Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger.
Brading questions
Will you come out to Brading?
Yes. Brading is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Does living near the coast affect sand mastic in Brading?
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 tenants book the work?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll tell you what we are using.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status, and we are fully insured.
Is sand mastic better than silicone for my windows?
For period timber windows in stone or brick, sand mastic is often the better fit. Modern frames normally suit a flexible sealant.
Do you have insurance?
Yes. We’re fully insured.
Brading homes and the weather
Brading 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. Historic houses like Morton Manor (about 0.4 miles south) are a reminder that the area around Brading has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
For site and facilities teams at buildings such as Brading Church of England Controlled Primary School, its window and door frames need their mastic kept sound, just like a home’s. Rented homes near Brading station change hands often, and any sash windows need sound mastic to keep draughts and rain out.

What we’re called out for in Brading
Decorating can disturb tired mastic. It’s often found when windows are being prepared for paint, which is a good time to renew it.
Any of these means the joints need attention:
- Failed mastic on an exposed elevation
- Mastic round period door frames that has failed
- A silicone bead on a sash window that spoils the look
- Tired mastic found when preparing windows for paint
For an older house near a landmark such as St. Mary's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

- Whether they’re fully insured
- Whether all the old sealant comes out first
