How we handle sand mastic in Branchton
Burnt sand mastic is a traditional material that sits naturally against stone and brick. It suits period and listed homes, where modern sealant can look out of place. We work on stone surrounds, brick reveals and period & listed homes, and people most often call us about weathered mastic on the most exposed windows and old cement repairs round a window that have failed.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
You are covered for a year from the day we finish. If anything isn’t right with it, send an email to info@mrmastic.co.uk.

Should I try DIY first?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

Frames and glazing around Branchton
Branchton is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around older windows and doors, especially on the side facing the sea. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
Historic houses such as Ardgowan House, about 2.8 miles south-west, show how far back building around Branchton goes. Managing a site like Inverclyde Academy? Then its window and door frames need their mastic kept sound, just like a home’s.

What the job involves on each surface
Period and listed homes
Sand mastic is the like-for-like choice for many period homes. On listed buildings, check with your planning authority first.
Tenement and terrace windows
Tenements and terraces often have many sash windows with ageing mastic. We can do one window or several.
DIY versus a professional finish
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, then guaranteed for a year.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Signs you need sand mastic in Branchton
Timber frames move with the seasons. That movement opens up the mastic joint little by little.
Most people get in touch after spotting one of these:
- Draughty sash windows at the surround
- Cracked mastic round a front door frame
- Modern sealant on a period surround
- Patchy fillers round a sash window

Looking after it afterwards
A little care helps the new joints last. Our advice:
- Check with your local planning authority if your home is listed
- Make sure water runs off the sill
- Plan mastic work ahead of painting
- Ask us before painting near the mastic
Avoid painting over the new mastic, as traditional guidance advises. Ask us before any decorating around it.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.
