Sand mastic in Westquarter, done properly
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. 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. We work on stone surrounds, tenement windows and period & listed homes, and the jobs we see most are mastic round period door frames that has failed and old sand mastic that has cracked, crumbled or fallen out.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
A 12-month guarantee comes as standard.

The process
At the end, we look at the finished work together and explain the cure time. The work normally takes a few hours per window, depending on the condition of the joints, depending on how much there is to do. Outdoor work around Westquarter depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We check the window surrounds and agree which joints need renewing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
How to prepare
- Try not to wet indoor joints just before the visit
- Tell us about any water getting in
- Move anything stored near the joints

Advice
Sand mastic in Westquarter: local notes
Westquarter 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. Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
If you live in an older home near Brightons Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Letting a property close to Polmont station? Then older sash windows in a rental need their mastic kept sound to keep the weather out.

Your questions about sand mastic in Westquarter
Do you work for landlords with property near Polmont station?
Yes, landlords and agents are among the people we work for. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we’ll send you a clear quote.
Does the coastal weather in Westquarter affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Can you quote for more than one area?
Yes. More than one area can go on one quote.
Can I paint the new mastic?
Sand mastic is normally left unpainted, as guidance on traditional windows advises. Talk to us before any painting near it.
Will you leave a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Do you guarantee sand mastic work?
All our work has a one-year guarantee, and we’re fully insured.
Can you replace silicone on a period window with sand mastic?
Often, yes. Once the silicone is out and the joint prepared, sand mastic is applied by hand.
Do you come to Westquarter?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland, Westquarter included.
How to look after the new joints
So the new joints stay in good condition:
- Avoid patching sand mastic with silicone
- Take care around the mastic when scraping paint
- Inspect the joints round the windows every year or so
- Make sure water runs off the sill
Leave the new mastic alone while it firms up. It forms a skin fairly soon but needs longer to fully harden.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.
What sealant work can’t fix
Before booking, it’s worth knowing the limits:
- Crumbling stone or brickwork round the window
- Whether work needs listed building consent
- Decayed frames that need repair
If you are not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer.
Surfaces we seal

Why it’s worth doing now in Westquarter
Draughts round a sash window aren’t always the sashes. Open mastic joints round the box can let air in, and renewing the mastic closes them. In a place like Westquarter, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

What else we do in Westquarter
Different surfaces, different methods
Tenement and terrace windows
Where a building is shared, window work may involve neighbours, so check who is responsible first.
Sash and case windows
Most of our sand mastic work is on sash windows. We renew the mastic round each box.
What we are called out for in Westquarter
Sand mastic slowly weathers. It hardens, cracks and starts to come away from the frame or the masonry.
Most people get in touch when they notice one of these:
- Modern sealant on a period surround
- Mastic round period door frames that has failed
- Draughts and rain around sash boxes
- Cement or filler used on old window joints that has cracked
Managing a site like Beancross Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.
