- Crumbling sand mastic round a window
- Gaps between timber frames and stone or brick
- Silicone on a period window that looks wrong
Can I do it myself?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
Sand mastic for homes and businesses in Prestongrange
Silicone on a period window often looks wrong and doesn’t suit the building. Sand mastic gives a finish that matches the age of the house and we can swap the silicone for it. Typical jobs include crumbling sand mastic round a window and wind and rain getting in round a sash window, on period & listed homes, timber door frames and tenement windows.
Outdoor sealant needs a dry surface, so window work around Prestongrange is planned around the weather. Let us know about access to every frame, including any upstairs.

Signs you need sand mastic in Prestongrange
Paint, silicone or cement used over old mastic causes problems. They don’t suit the joint, and they usually need raking out.
These are the problems we are asked about most:
- Old cement repairs round a window that have failed
- Cracked mastic round a front door frame
- Old sand mastic that has cracked, crumbled or fallen out
- Draughts and rain around sash boxes
Homes close to Prestongrange Parish Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Frames and glazing around Prestongrange
Prestongrange is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
For landlords with property near Prestonpans station, older sash windows in a rental need their mastic kept sound to keep the weather out. Schools such as Preston Lodge High School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Nearby you’ll also find Royal Infirmary of Edinburgh (5.8 miles west) and Battle of Prestonpans Jacobite Museum (0.5 miles north-east).
Why deal with it now?
New mastic over crumbling mastic won’t hold. Raking out and preparing the joint gives it a sound base so the new mastic stays put. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.

What we cannot put right
New sealant can’t fix everything, and we’ll tell you before any work starts. It will not solve:
- Whether work needs listed building consent
- Masonry that needs repairing
- Rotten sashes, sills or window boxes (a joiner’s job)
If in doubt, email us at info@mrmastic.co.uk and we will say what we think before booking.
What we seal
- Period & listed homes
- Sash and case windows
- Timber door frames
- Stone surrounds
- Tenement windows
- Brick reveals
Different surfaces, different methods
Stone surrounds
Stone openings are rarely perfectly straight, so the joint varies in width. We shape it by hand to follow the stone.
Timber door frames
Round a period front door, sand mastic gives the right look.
