Different surfaces, different methods
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.
Sash and case windows
The box of a sash and case window sits in the stone or brick opening. Sand mastic seals the joint round it.
Sand mastic in Yaverland
Silicone on a period window often looks wrong and isn’t always the right material. Sand mastic is the traditional choice and we can swap the silicone for it. If you are dealing with mastic dropping out of the joint and modern sealant on a period surround, we can help.
Somewhere as small as Yaverland, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
All of our work is guaranteed for twelve months, in Yaverland and everywhere else we cover.

Signs you need sand mastic in Yaverland
Shallow joints are a common cause. A thin layer does not hold well so we make sure the new mastic is the right thickness.
These are the problems we’re asked about most:
- Cracked mastic round a front door frame
- Weathered mastic on the most exposed windows
- Gaps where the frame meets the masonry
- Old sand mastic that has cracked, crumbled or fallen out
Letting a property close to Brading station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about.
Questions to ask before booking
- What the quote includes, VAT included or not
- Whether all the old sealant comes out first
- Which sealant they’ll use, and why
- The length of the guarantee
What happens on the day
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes anything from a few hours to a full day, depending on how many windows. For a village or hamlet like Yaverland, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- Large voids are packed out first, so the mastic isn’t too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about earlier repairs to the joints

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Your questions about sand mastic in Yaverland
Does the coastal weather in Yaverland affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Do you work for landlords with property near Brading station?
Yes, we work for landlords and letting agents. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before we start.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access.
Will the old sealant be removed?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.
Do you guarantee sand mastic work?
Every job comes with our one-year guarantee.
How long does the job take?
That depends on the amount of work, but most jobs take a few hours per window, depending on the condition of the joints. We’ll tell you when we quote.
What does sand mastic cost?
It depends on the job, so we quote each one individually. For a quick quote, ring 0345 464 0079 or email us with a short description of the job.
What’s sand mastic made of?
A traditional pointing material made from sand and a linseed-oil-based binder, used between timber frames and stone or brick.
What sand mastic looks like in Yaverland
Yaverland is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s 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, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For an older house near a landmark such as St John the Baptist Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For site and facilities teams at buildings such as The Bay Church of England School, its window and door frames need their mastic kept sound, just like a home’s.

Keeping the joints in good condition
So the new joints stay in good condition:
- Avoid heavy scraping on the mastic joint
- Ask us before painting near the mastic
- Keep sills and gutters clear so water drains away
- Inspect the joints round the windows every year or so
Leave the new mastic alone while it firms up. It forms a skin fairly soon, but takes longer to harden fully.
Sound mastic protects the frame. Failed mastic lets water reach the timber and timber that stays wet can rot.
Landlords, agents and businesses in Yaverland
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
Letting agents often deal with us directly. Tell us the address, the job and how access works.
