Sand mastic for homes and businesses in Temple
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s made from sand and a linseed-oil-based binder and built up by hand. On period homes, it looks right where silicone wouldn’t. Typical jobs include mastic dropping out of the joint and failed mastic on an exposed elevation, on tenement windows, brick reveals and sash and case windows.
Somewhere as small as Temple, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.

What you pay reflects the work, not a rough estimate. That is why we ask about the job first and send you a clear quote before any work starts.
What we need to know
When you call or email, these details help:
- What’s wrong with the joints now
- If someone has resealed it before
- Photos by email, if that is easy
- Where the job is, and your postcode
We don’t publish a price list. Instead, we give you a clear price for your job. To get started, call 0345 464 0079 or drop us an email.
What the job involves on each surface
Stone surrounds
Old stone surrounds are often uneven, so the joint varies in width. Sand mastic is shaped by hand to suit.
Tenement and terrace windows
Windows above ground floor need the right access. Tell us the height and we will confirm what’s needed.

Temple homes and the weather
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Harleyford Manor (about 0.9 miles west) are a reminder that the area around Temple 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’s traditional sand mastic.
If you look after a building such as Bisham Church of England Academy, larger buildings have plenty of frames, and the mastic around each one ages. For an older house near a landmark such as Church of All Saints, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For landlords with property near Marlow station, older sash windows in a rental need their mastic kept sound to keep the weather out.

Aftercare tips
To keep the joints looking good and working properly:
- Ask the planning authority about consent for listed or conservation-area homes
- Sort the mastic before the decorators arrive
- Ask a joiner to look at soft timber first
- Keep sills and gutters clear so water drains away
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.
For landlords and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
When it isn’t the sealant
Before you book, it’s worth knowing the limits:
- Rotten sashes, sills or window boxes (a joiner’s job)
- Broken panes
- Planning or listed building consent (your local planning authority decides)
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly.
What we seal
- Stone surrounds
- Sash and case windows
- Timber door frames
- Period & listed homes
- Brick reveals
- Tenement windows
What happens if it’s left?
Not every filler suits an old window surround. Sand mastic is the like-for-like choice and that can be important for listed homes. Older cottages and farmhouses around Temple can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we will explain what it covers.
