Sand mastic in Garmouth
Silicone on a period window often looks wrong and doesn’t suit the building. Sand mastic is the traditional choice and we can swap the silicone for it. Common call-outs are for weathered mastic on the most exposed windows and gaps between timber frames and stone or brick, across sash and case windows, brick reveals and timber door frames.
Mastic can only go onto a dry joint, so outside work in Garmouth depends on the weather. Tell us about access to all the windows and doors, upstairs included.
Each job carries a 12-month guarantee, large or small.

When something else is needed
We’ll always be straight with you, so here’s what sealant can’t fix:
- Whether work needs listed building consent
- Decayed frames that need repair
- Damaged stone surrounds

Where we work in Garmouth
- Stone surrounds
- Period & listed homes
- Tenement windows
- Brick reveals
- Timber door frames
- Sash and case windows
Looking after it afterwards
So the new joints stay in good condition:
- Plan mastic work ahead of painting
- Look over the window mastic once a year
- Ask us before painting near the mastic
- Avoid heavy scraping on the mastic joint
Look at the mastic when you look over the windows. Catching cracks early keeps repairs small.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.
What we are called out for in Garmouth
Water gets into small cracks in the mastic and loosens it further. Exposed elevations generally fail first.
Signs it’s time to call us include:
- Mastic worn away on windows facing the weather
- Mastic that needs renewing before redecorating
- Mastic round period door frames that has failed
- A silicone bead on a sash window that spoils the look
If you live in an older home near Garmouth Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Surface by surface
Sash and case windows
A sash window’s box frame sits in the masonry opening. The gap round it is pointed with sand mastic.
Tenement and terrace windows
Where a building is shared, window work may involve neighbours, so check who is responsible first.
What we do, step by step
You don’t need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the job takes anything from a few hours to a full day, depending on how many windows for a typical job. Outdoor work around Garmouth depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- 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
- Keep pets and children clear of the area while we work
- Tell us about any water getting in
- Mention any tricky access

Advice
Windows and doors in Garmouth
Garmouth 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. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
Around Garmouth, as everywhere, sand mastic is only as good as the preparation behind it.

Garmouth: your questions answered
Is sand mastic in a coastal place like Garmouth any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are normally the first to need attention.
Can you do sand mastic in Garmouth?
Yes. We work across all of Scotland, and Garmouth is part of that. Just email us at info@mrmastic.co.uk with a few details of the job.
Where do you work from?
We are a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done and you’ll get one quote.
Is it possible to take out silicone and use sand mastic instead?
Usually, yes. Once the silicone is out and the joint prepared, sand mastic is applied by hand.
Are you an approved applicator?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Should I use sand mastic or silicone?
For period timber windows in stone or brick, sand mastic is often the better fit. Modern frames normally suit a flexible sealant.
Is the work guaranteed?
You get our 12-month guarantee to all our work.
