Signs you need sand mastic in Bràigh na h-Aoidhe
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.
Most people get in touch when they notice something like this:
- Tired mastic found when preparing windows for paint
- Gaps round a timber door in stone or brick
- Cement or filler used on old window joints that has cracked
- Weathered mastic on the most exposed windows
In the older streets around St Columba's Church, the joint between an old wall and a newer frame is normally the first place rain gets in.

Sand mastic in Bràigh na h-Aoidhe
Silicone on a period window often looks wrong and is not always the right material. Sand mastic is the traditional choice, and we can replace one with the other. We’re often asked to deal with patchy fillers round a sash window and wind and rain getting in round a sash window, on timber door frames, sash and case windows and brick reveals.
Mastic can only go onto a dry joint, so outside work in Bràigh na h-Aoidhe depends on the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
Big or small, you get the same one-year guarantee.

Why act early in Bràigh na h-Aoidhe
Draughts round a sash window are not always the sashes. Gaps between the frame and the wall can be just as bad, and renewing the mastic closes them. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part.

- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.

Bràigh na h-Aoidhe homes and the weather
Bràigh na h-Aoidhe 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.
Around Bràigh na h-Aoidhe, as everywhere, sand mastic is only as good as the preparation behind it.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Take care around the mastic when scraping paint
- Keep modern sealant off the mastic
- Make sure water runs off the sill
- Renew mastic before redecorating the windows
Look at the mastic when you look over the windows. Catching cracks early keeps repairs small.
Sound mastic protects the frame. Failed mastic lets water reach the timber, which can lead to rot.
Bràigh na h-Aoidhe questions
Do you cover smaller places like Bràigh na h-Aoidhe?

Yes, Bràigh na h-Aoidhe is within the area we cover. Our work covers the whole of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Is it possible to paint over sand mastic?
It’s traditionally left unpainted, as guidance on traditional windows advises. Ask us before decorating.
How long will you be here?

Can you replace silicone on a period window with sand mastic?
Yes. The silicone is cut out and the joint cleaned before the sand mastic goes in.
Do you do commercial work?
Yes, regularly. Larger jobs can be planned room by room or area by area.
For landlords and businesses
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.

What else we do in Bràigh na h-Aoidhe
Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
