DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Sand mastic for homes and businesses in Wisley
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s a mix of sand and a linseed-oil-based binder and built up by hand. On older homes, it suits the building far better than silicone. If you are dealing with mastic worn away on windows facing the weather and gaps between timber frames and stone or brick, we can put it right.
Homes in small places like Wisley often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
We stand behind the work with a 12-month guarantee, so you are covered after we’ve gone.

The problems people normally mention when they call include:
- Draughts and rain around sash boxes
- Old cement repairs round a window that have failed
- Failed mastic on an exposed elevation
- A silicone bead on a sash window that spoils the look
If you let a flat or house near West Byfleet station, any sash windows need sound mastic to keep draughts and rain out.

FAQs for Wisley
Do you cover smaller places like Wisley?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Is Wisley in your area for sand mastic?
Yes. Our work covers London and the South East, and Wisley is part of that. Just call 0345 464 0079 or email us with a few details of the job.
Can you replace silicone on a period window with sand mastic?
In most cases. The silicone is cut out and the joint cleaned before the sand mastic goes in.
What exactly is sand mastic?
A traditional pointing material made from sand and a linseed-oil-based binder for the joint between timber frames and masonry.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Can I paint the new mastic?
It’s traditionally left unpainted, as guidance on traditional windows advises. Talk to us before any painting near it.
Is it OK to seal over old sealant?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Can I add another job to the visit?
Yes. More than one area can be quoted together.
Wisley homes and the weather
Historic houses like Byfleet Manor (about 0.8 miles north-east) are a reminder that the area around Wisley has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you live in an older home near Wisley Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. For site and facilities teams at buildings such as St Mary's CofE Controlled Primary School, the mastic around its windows and doors needs looking after like any other building’s.

Related advice
Leave it or put it right?
Cement-based fillers and modern sealants don’t always suit a period surround. Sand mastic is the like-for-like choice and that can be important for listed homes. In a small place like Wisley, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.
