Sand mastic in Cheriton, done properly
If your home is listed or in a conservation area, check with your local planning authority if consent is needed before window work. Sand mastic is often favoured as a like-for-like material. If you have silicone on a period window that looks wrong and old sand mastic that has cracked, crumbled or fallen out, we can help.
Somewhere as small as Cheriton, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
Whatever the size of the job, it’s backed by our 12-month guarantee in Cheriton and across Hampshire.

Advice
Frames and glazing around Cheriton
Historic houses like Hinton Ampner House (about 0.8 miles south-east) are a reminder that the area around Cheriton has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
Homes close to Church of St Michael include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Questions from Cheriton
Will you come out to Cheriton?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you do sand mastic in Cheriton?
Yes, Cheriton is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear quote.
What information do you need?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Can sand mastic be painted?
Traditional guidance is not to paint over sand mastic. Ask us before you decorate around it and we will advise.
Will there be a smell?
That depends on the sealant. Some products have a noticeable smell, others very little.
Do I need to be at home?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that usually means someone at home.
When will the new mastic be hard?
It takes a while. It skins first and hardens fully later and we will give you an idea for your job.
Can old silicone round a sash window be swapped for sand mastic?
Yes. The silicone is cut out and the joint cleaned, then point it with sand mastic.
For landlords and businesses
Hotels need rooms back in use, so we plan the work room by room. We’ve worked in hotels as well as homes and businesses.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Different surfaces, different methods
Timber door frames
Door frames get knocked and soaked, so their mastic can fail sooner. We rake it out and renew it.
Brick reveals
Gaps between frame and brick let in rain and draughts. New mastic seals the gap.
When something else is needed
Before you book, it’s worth knowing the limits too:
- Cracked or broken glass
- Sashes that need overhauling
- Whether work needs listed building consent
If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before booking.

Also in Cheriton
Do you need sand mastic in Cheriton?
Sand mastic slowly weathers. It hardens, cracks and starts to come away on the stone or timber.
If you can see any of these, it’s time to have the joints looked at:
- Wind and rain getting in round a sash window
- Crumbling sand mastic round a window
- Failed mastic on an exposed elevation
- Gaps round a timber door in stone or brick
Schools such as Cheriton Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

How we quote for sand mastic
The quote reflects the job in front of us. We look at:
- Any working-time requirements on site

Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we will explain what it covers.
Helping us quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Where the job is, and your postcode
- The problem you’ve noticed
- If it’s domestic, commercial or a hotel
- Photos by email, if that is easy
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.
How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Leave the new mastic unpainted
- Take care around the mastic when scraping paint
- Inspect the joints round the windows every year or so
- Keep modern sealant off the mastic
Do not run silicone over the new mastic. If you see a crack, ask us to take a look before trying a quick fix.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.
