Sand mastic for homes and businesses in Scadabhagh
Sand mastic doesn’t last for ever, leaving gaps round the window. Renewing it closes the gap and tidies the surround. Common call-outs are for tired mastic found when preparing windows for paint and wind and rain getting in round a sash window, across sash and case windows, tenement windows and period & listed homes.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
Big or small, you get the same one-year guarantee in Scadabhagh and across Na h-Eileanan Siar.

What happens if it’s left?
Not every draught comes from the sashes themselves. Open mastic joints round the box can let air in, and renewing the mastic closes them. In a place like Scadabhagh, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

Questions from Scadabhagh
Does living near the coast affect sand mastic in Scadabhagh?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Will you come out to Scadabhagh?
Yes, we do. Our work covers the whole of Scotland, islands included, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
What does sand mastic cost?
Every job is different, so each one gets its own quote. To get one, send an email to info@mrmastic.co.uk and tell us what needs doing and where.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Do I need permission for sand mastic on a listed building?
Yes, it’s worth checking. Ask your local planning authority whether consent is needed for listed or conservation-area properties.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Is it messy?
No. We protect the surfaces around the joints, and we tidy up before we go.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures.
How the visit works
When we arrive, we start by going over the job with you, so you know exactly what we’re doing. We protect the surfaces around the joints before any work starts. Most jobs take a few hours for a single window, longer for several. In smaller Scottish places, parking is usually less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- Each surround is checked first.
- The joint is raked out and cleaned.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Clear the area around the work
- Let us know about earlier repairs to the joints
How to get a quote
Asking for a quote is easy: tell us what needs doing and where, and roughly how big it is. Photos by email help us understand the job.
Advice
Different surfaces, different methods
Tenement and terrace windows
In shared buildings, the windows may be part of a wider repair so it’s worth checking responsibilities.
Sash and case windows
The box of a sash and case window sits in the stone or brick opening. Sand mastic seals the joint round it.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Ask the planning authority about consent for listed or conservation-area homes
- Renew mastic before redecorating the windows
- Make sure water runs off the sill
- Get any rot dealt with first
Leave the new mastic alone while it firms up. It forms a skin fairly soon but needs longer to fully harden.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.
What affects the quote in Scadabhagh

Frames and glazing around Scadabhagh
Scadabhagh is within about 1 mile of 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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
For jobs in and around Scadabhagh, choosing the right material for each joint is as important as a tidy finish. Around Scadabhagh, as everywhere, sand mastic is only as good as the preparation behind it.
