Sand mastic in Swan Street, done properly
Silicone on a period window often looks wrong and does not suit the building. Sand mastic is the traditional choice and we can swap the silicone for it. We work on sash and case windows, timber door frames and tenement windows, and the jobs we see most are mastic that needs renewing before redecorating and open joints round the window box.
Around Swan Street, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
A one-year guarantee comes as standard.

For landlords and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
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.

Advice
How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Plan mastic work ahead of painting
- Avoid heavy scraping on the mastic joint
- Ask the planning authority about consent for listed or conservation-area homes
- Inspect the joints round the windows every year or so
Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look before trying a quick fix.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall, so renewing it early is worth it.

Surface by surface
Stone surrounds
Stone surrounds suit sand mastic well. It finishes to look like part of the surround.
Period and listed homes
Many older homes were built with sand mastic round the windows. If your home is listed, ask your local planning authority about consent.
Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
