Sand mastic in Shortheath
Sand mastic skins over fairly quickly but full hardening takes longer. Traditional guidance is not to paint over it and we’ll advise if you are redecorating. If you have old sand mastic that has cracked, crumbled or fallen out and window mastic to renew ahead of painting, we can put it right, on period & listed homes, sash and case windows and stone surrounds alike.
Mastic can only go onto a dry, clean joint, so window work in Shortheath is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Your job is guaranteed for a year, as with all our work.

DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
A careful DIYer can reseal a simple joint, 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.
Aftercare tips
Aftercare is simple:
- Go gently near the mastic when preparing windows
- Avoid patching sand mastic with silicone
- Leave the new mastic unpainted
- Look over the window mastic once a year
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.
Frames and glazing around Shortheath
Historic houses like Farnham Castle (about 1.6 miles north) are a reminder that the area around Shortheath 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. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Rented homes near Farnham station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. For site and facilities teams at buildings such as St Peter's CofE Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Advice

Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
When to call us in Shortheath
Over the years, sand mastic weathers. It hardens, cracks and starts to come away from the frame or the masonry.
Common reasons people contact us include:
- Draughty sash windows at the surround
- Mastic worn away on windows facing the weather
- Open joints round the window box
- Patchy fillers round a sash window
For an older house near a landmark such as St Peter's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What else we do in Shortheath
Why deal with it now?
If you are redecorating, renew the mastic first. Painting over failed mastic does not seal it, and the new mastic is traditionally left unpainted. Older cottages and farmhouses around Shortheath can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint generally makes the job bigger, not smaller. If you are not sure whether it needs doing, phone 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.

Shortheath: your questions answered
Do you cover Shortheath for sand mastic?
Yes. We work across London and the South East, and Shortheath is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear price.
I let a flat near Farnham station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just ring 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear price.
Can I choose the sealant colour?
We help you choose a colour that suits. The choice depends on the product the joint needs.
Can old silicone round a sash window be swapped for sand mastic?
Yes, we do this often. The old silicone has to come out completely so the mastic beds in well.
Will it make a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Can you seal over the old sealant?
No, because it fails. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
What’s sand mastic made of?
It’s sand mixed with a linseed-oil-based binder, used between timber frames and stone or brick.
Is sand mastic better than silicone for my windows?
We’ll talk it through with you. Period homes often look best with sand mastic, and modern sealants suit newer frames.
