Sand mastic in Bearsden, done properly
Old sand mastic cracks, crumbles and falls out over time, leaving gaps round the window. We rake it out and renew it so the surround looks right again. We work on timber door frames, stone surrounds and sash and case windows, and people most often call us about cracked mastic round a front door frame and old sand mastic that has cracked, crumbled or fallen out.
In a town like Bearsden, stone-built older streets generally sit alongside harled houses and newer estates, and windows range from older sash and case to modern uPVC. Each needs the right sealant against the right wall.
All our work comes with a one-year guarantee.

What sand mastic looks like in Bearsden
Bearsden is in the west of Scotland, which is wetter than the east, which means the mastic around older windows and doors has to cope with a lot of rain. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.
Rented homes near Bearsden station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. Schools such as Bearsden Academy are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.
Bearsden is about 5 miles north-west of Glasgow, in East Dunbartonshire.

How the job changes by surface
Sash and case windows
The mastic round a sash window is on show, so a neat, even finish matters.
Tenement and terrace windows
Upper-floor windows need access planning. Let us know the floor and we will confirm access.
What we are called out for in Bearsden
Paint, silicone or cement used over old mastic causes problems. They do not suit the joint, and they generally need raking out.
Signs it’s time to call us include:
- Mastic worn away on windows facing the weather
- Crumbling sand mastic round a window
- Wind and rain getting in round a sash window
- Modern sealant on a period surround
Historic houses such as Tenement House, about 4.4 miles south-east, show how far back building around Bearsden goes, and older homes nearby need a sealant that suits their walls.

Why deal with it now?
Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic suits the building and blends with the stone or brick. In Bearsden, wind and rain soon get through failed outside joints. Indoors, failed sealant lets water into floors and ceilings.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we will go through it with you.

How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Renew mastic before redecorating the windows
- Get any rot dealt with first
- Make sure water runs off the sill
- Avoid heavy scraping on the mastic joint
Don’t touch or press the mastic while it hardens. It forms a skin fairly soon, but takes longer to harden fully.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall, so renewing it early is worth it.
The process
Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours per window, depending on the condition of the joints. Parking around Bearsden is rarely difficult, though older streets in the centre can be tight. For flats, mention the shared stair or door entry system.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.
How to prepare
- Let us know if you’ve seen damp or leaks
- Plan for the work area to be out of bounds to pets and children
- Move anything stored near the joints
