How we handle sand mastic in Rothesay
Traditional burnt sand mastic blends with stone and brick surrounds. It suits period and listed homes, where modern sealant can look out of place. We work on sash and case windows, brick reveals and tenement windows, and the jobs we see most are mastic round period door frames that has failed and tired mastic found when preparing windows for paint.
Mastic can only go onto a dry joint, so outside work in Rothesay depends on the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
Big or small, it’s backed by our one-year guarantee in Rothesay and across Argyll and Bute.

Rothesay homes and the weather
Rothesay is within about 1 mile of 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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
If you look after a building such as Rothesay Academy, its window and door frames need their mastic kept sound, just like a home’s.

Leave it or put it right?
Draughts round a sash window aren’t always the sashes. Gaps between the frame and the wall can be just as bad and new mastic seals them. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first.

Do you need sand mastic in Rothesay?
Shallow joints are a common cause. Mastic that’s too thin cracks and drops out, which is why we pack deep voids first and get the depth right.
Look out for any of the following:
- Patchy fillers round a sash window
- Window mastic to renew ahead of painting
- Draughts and rain around sash boxes
- Gaps between timber frames and stone or brick
For an older house near a landmark such as St Andrews R.C. Church Hall, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Other services in Rothesay
Different surfaces, different methods
Tenement and terrace windows
Windows above ground floor need the right access. Let us know the floor and we’ll confirm access.
Sash and case windows
On a sash window, the mastic joint shows on the outside, so a neat, even finish matters.
The process
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the job takes a few hours per window, depending on the condition of the joints for a typical job. For a place like Rothesay, 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.
- Old, loose mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- The mastic is mixed, pressed into the joint by hand and shaped.
- We dress the surface so it sits neatly against the masonry.
Preparing for the visit

Which is right for my windows, sand mastic or modern sealant?
We’ll help you decide. Period homes often look best with sand mastic, and modern sealants suit newer frames.
What information do you need?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply email us at info@mrmastic.co.uk.
Should I check with the council before work on a listed or conservation-area home?
Yes, it’s worth checking. Ask your local planning authority whether consent is needed for listed or conservation-area properties.
Do you work for landlords and businesses?
Yes. We work for homeowners, landlords, letting agents, businesses and hotels.
Will the old sealant be removed?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
Is there any odour?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Clear gutters so water does not pour onto the windows
- Keep modern sealant off the mastic
- Look over the window mastic once a year
- Take care around the mastic when scraping paint
Don’t touch or press the mastic while it hardens. It forms a skin fairly soon, but takes longer to harden fully.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.
