Sand mastic in Viables, 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. Like-for-like sand mastic is often the preferred finish. Typical jobs include open joints round the window box and gaps round a timber door in stone or brick, on stone surrounds, timber door frames and period & listed homes.
Many houses in smaller places like Viables have conservatories, garden rooms or patio doors. Their glazing joints and frame seals are as much a part of the job as the windows.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or email us.

Questions from Viables
Do you cover Viables for sand mastic?
Yes. Our work covers London and the South East, and Viables is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear price.
Is Viables within the area you cover?
Yes. Viables is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can new sealant go over the old?
No, it will not last. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
Which is right for my windows, sand mastic or modern sealant?
We will talk it through with you. Period homes often look best with sand mastic, and modern sealants suit newer frames.
How long does sand mastic take to harden?
It takes a while. It skins first and hardens fully later, and we will tell you what to expect.
Does someone need to be in?
We need access to the joints, so we will agree that with you when we book. Indoors, that generally means someone at home.
Can you match the sealant colour?
Most of the time, yes. We will explain which colours are available and agree one before work begins.
Do you work for hotels and businesses?
Yes. We can plan bigger jobs in stages to suit the site.

How the visit works
There isn’t much for you to do on the day. Point us to the joints and we’ll get on with it. The work itself takes anything from a few hours to a full day, depending on how many windows, including the tidy-up. Parking around Viables is generally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- 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.
How to prepare
- Mention any tricky access
- For business premises, tell us about site rules or sign-in
- Plan for the work area to be out of bounds to pets and children

Advice
What affects the quote in Viables
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The size of the job
- Which sealant suits the joint
- Any working-time requirements on site
- The old material and how stubborn it is
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and agree the price before starting.

Do you need sand mastic in Viables?
Rain on the window surround works into any crack and pushes it out. Windows facing the weather tend to go first.
Signs it’s time to call us include:
- Mastic worn away on windows facing the weather
- Patchy fillers round a sash window
- Mastic that needs renewing before redecorating
- Draughty sash windows at the surround
If you look after a building such as St John's Church of England Voluntary Aided Primary School, the mastic around its windows and doors needs looking after like any other building’s.

Windows and doors in Viables
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like The Vyne (about 3.9 miles north) are a reminder that the area around Viables has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Rented homes near Basingstoke station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about. Homes close to Church of All Saints include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Why deal with it now?
Gaps round a sash window let in rain and draughts. Water can get to the frame and the masonry, so dealing with it now protects both. Homes in smaller places like Viables can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.

How the job changes by surface
Sash and case windows
The mastic round a sash window is on show, so a neat, even finish matters.
Stone surrounds
Stone openings are rarely perfectly straight, so the gap is not the same all the way round. We shape it by hand to follow the stone.
Aftercare tips
Aftercare is simple:
- Sort the mastic before the decorators arrive
- Do not paint over the new mastic
- Check the mastic when you check the paintwork
- Keep modern sealant off the mastic
Avoid sealing over the mastic with silicone. If anything cracks, get it looked at rather than patching it.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
