Sand mastic for sash & case windows in Little Atherfield, Isle of Wight
Professional sand mastic in and around Little Atherfield, with every bit of old sealant taken out first and a 12-month guarantee.
- Draughts and rain around sash boxes
- Mastic round period door frames that has failed
- Mastic dropping out of the joint
Why act early in Little Atherfield
Not every draught comes from the sashes themselves. Gaps between the frame and the wall can be just as bad and new mastic seals them. Around Little Atherfield, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.

Sand mastic for homes and businesses in Little Atherfield
Across Little Atherfield, we renew sand mastic around sash and case windows. Each joint is raked out, prepared and pointed by hand, finished to suit the masonry. If you have weathered mastic on the most exposed windows and modern sealant on a period surround, we can put it right, on timber door frames, stone surrounds and tenement windows alike.
Around Little Atherfield, 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.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Common questions in Little Atherfield
Is sand mastic in a coastal place like Little Atherfield any different?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Do you cover smaller places like Little Atherfield?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
What guarantee comes with the work?
There’s a 12-month guarantee on every job, sand mastic included.
Can you seal over the old sealant?
No, it won’t last. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Do you work for landlords and businesses?
Yes, regularly. We can quote for several properties at once, and between tenancies is a good time for the work.
Are you fully insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
When will the new mastic be hard?
A skin forms quite soon, but full hardening takes longer. We will explain what to expect before we leave.
Is it possible to paint over sand mastic?
Traditional guidance is not to paint over sand mastic. Ask us before you decorate around it and we’ll advise.
What we can’t put right
We will not take on work that will not last, so these are the limits:
- Decisions on consent for listed homes
- Sashes that rattle, stick or will not open
- Timber that has rotted
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think before you book.

Surface by surface
Period and listed homes
Materials matter on listed and conservation-area homes. Sand mastic is often the preferred finish.
Stone surrounds
Old stone surrounds are often uneven, so the joint varies in width. We shape it by hand to follow the stone.

Windows and doors in Little Atherfield
Little Atherfield 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’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.

What affects the cost of sand mastic
You’ll get a clear quote before any work starts. It takes into account:
- The type of sealant required
- Whether there’s mould to deal with
- The old material and how stubborn it is
- The number of rooms or windows
The cost depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.
Helping us quote
You don’t need to know the technical terms. Just tell us:
- Whether it’s a home or a business
- If someone has resealed it before
- The rough size of the job
- Where the property is
It all starts with a short chat. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. Whenever you’re ready, call 0345 464 0079 or email us.
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Take care around the mastic when scraping paint
- Ask us before painting near the mastic
- Sort the mastic before the decorators arrive
- Clear gutters so water does not pour onto the windows
Leave the new mastic unpainted, which is the traditional advice. Ask us before any decorating around it.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.
How it works
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. It normally takes anything from a few hours to a full day, depending on how many windows. In a small place like Little Atherfield, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic is not too thick.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- For indoor joints, keep the area dry beforehand if you can
- For business premises, tell us about site rules or sign-in
