About our sand mastic in Spittal
A silicone bead around a sash window can look out of place and isn’t always the right material. Sand mastic is the traditional choice and we can swap the silicone for it. Common call-outs are for gaps between timber frames and stone or brick and mastic round period door frames that has failed, on timber door frames, brick reveals and sash and case windows.
In and around a place like Spittal, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill.
The work is covered for a year after we finish. If there’s a problem with it, please send an email to info@mrmastic.co.uk.

Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Clear gutters so water does not pour onto the windows
- Do not paint over the new mastic
- Inspect the joints round the windows every year or so
- Plan mastic work ahead of painting
Make sure water drains away from the window surround. Constant wetting wears the mastic faster.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.
What we are called out for in Spittal
Shallow joints are a common cause. A thin layer does not hold well, which is why we pack deep voids first and get the depth right.
Keep an eye out for these signs:
- Patchy fillers round a sash window
- Modern sealant on a period surround
- Mastic round period door frames that has failed
- Wind and rain getting in round a sash window
For landlords with property near Croftfoot station, any sash windows need sound mastic to keep draughts and rain out.

What sand mastic looks like in Spittal
Historic houses like Provand's Lordship (about 3.2 miles north) are a reminder that the area around Spittal has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
Schools such as Stonelaw High School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around Stonelaw Parish Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Advice
Common questions in Spittal
Is Spittal within the area you cover?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.

Yes. We work for letting agents and landlords as well as householders. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear price.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all.
Should I check with the council before work on a listed or conservation-area home?
Your local planning authority is the one to ask. They’ll tell you if consent is needed.
What exactly is sand mastic?
A traditional pointing material made from sand and a linseed-oil-based binder, used between timber frames and stone or brick.
Can you replace silicone on a period window with sand mastic?
In most cases. We remove the silicone and clean the joint before the sand mastic goes in.
How long does sand mastic take to go off?
A skin forms quite soon, but full hardening takes longer. We’ll tell you what to expect for your job.
Can you seal over the old sealant?
No, it will not last. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.

DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We cut it out and start again.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What the job involves on each surface
Brick reveals
Sand mastic is also used where timber frames meet brick. It gives a traditional finish.
Stone surrounds
Sand mastic sits naturally against stone. It finishes to look like part of the surround.
