How we handle sand mastic in Sgiogarstaigh
Silicone on a period window often looks wrong and is not always the right material. Sand mastic gives a finish that matches the age of the house and we can swap the silicone for it. We work on sash and case windows, period & listed homes and tenement windows, and the jobs we see most are failed mastic on an exposed elevation and window mastic to renew ahead of painting.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

What else we do in Sgiogarstaigh
What the job involves on each surface
Period and listed homes
A traditional finish suits a period property.
Stone surrounds
Old stone surrounds are often uneven, so the joint varies in width. Sand mastic is shaped by hand to suit.
Common questions in Sgiogarstaigh
Do you cover smaller places like Sgiogarstaigh?
Yes, Sgiogarstaigh is covered. We work across all of Scotland, islands included, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is sand mastic in a coastal place like Sgiogarstaigh any different?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
I rent my home. Can I book you?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we’re fully insured.
Do you offer different sealant colours?
Generally, yes. White, clear and grey are common, and other colours are available for many products, and we agree the colour with you before we start.
What do you need from me for a quote?
Only a few details: where it is, what you’ve noticed and how we reach it. Then email us at info@mrmastic.co.uk.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.

When something else is needed
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Whether work needs listed building consent
- Damaged stone surrounds
- Broken panes
If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think before you book.
Where we work in Sgiogarstaigh
- Brick reveals
- Timber door frames
- Sash and case windows
- Period & listed homes
- Tenement windows
- Stone surrounds
Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Check with your local planning authority if your home is listed
- Keep sills and gutters clear so water drains away
- Inspect the joints round the windows every year or so
- Go gently near the mastic when preparing windows
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens.
Common problems we fix in Sgiogarstaigh
Previous repairs in cement or silicone often trap water or crack away. They don’t move with the timber and we normally remove them.
These are the problems we’re asked about most:
- Cement or filler used on old window joints that has cracked
- Weathered mastic on the most exposed windows
- Crumbling sand mastic round a window
- Open joints round the window box
In and around Sgiogarstaigh, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.
Before you book anyone
- Whether VAT is included
- What product goes in the joint
- Which colour the sealant will be
- The length of the guarantee
What happens on the day
There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the work takes a few hours for a single window, longer for several in most cases. For a place like Sgiogarstaigh, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We check the window surrounds and agree which joints need renewing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.
Preparing for the visit
- Mention any parking rules near the property
- Clear items away from the joints we’re working on
- Mention if the joints have been sealed before

Related advice
Sgiogarstaigh homes and the weather
Sgiogarstaigh is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. 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.
For jobs in and around Sgiogarstaigh, choosing the right material for each joint is as important as a tidy finish.
