Sand mastic in Braehoulland, done properly
Across Braehoulland, we renew sand mastic around sash and case windows. Each joint is raked out, prepared and pointed by hand for a neat, traditional finish. We work on tenement windows, period & listed homes and sash and case windows, and people most often call us about window mastic to renew ahead of painting and modern sealant on a period surround.
Mastic can only go onto a dry joint, so outside work in Braehoulland depends on the weather. Tell us about access to all the windows and doors, upstairs included.
Each job carries a 12-month guarantee, whatever its size.

For landlords and businesses
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will give you a quote.
In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
How to look after the new joints
Looking after new joints is easy:
- Plan mastic work ahead of painting
- Avoid heavy scraping on the mastic joint
- Ask us before painting near the mastic
- Get any rot dealt with first
Avoid painting over the new mastic, which is the traditional advice. Ask us before any decorating around it.
An open joint round the box lets weather through. Left, the gap tends to get bigger.

Braehoulland questions
Can you do sand mastic in Braehoulland?
Yes. We work across all of Scotland, and Braehoulland is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job, and we’ll send you a clear quote.
Does living near the coast affect sand mastic in Braehoulland?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Do you offer different sealant colours?
Usually, yes. White, clear and grey are common, and other colours are available for many products, and we agree the colour with you before any work starts.
Should I check with the council before work on a listed or conservation-area home?
Checking first is sensible. Ask your local planning authority whether consent is needed for work on a listed home or in a conservation area.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Can you replace silicone on a period window with sand mastic?
Yes. The silicone is cut out and the joint cleaned, then point it with sand mastic.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Will you leave a mess?
We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.
DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
What sealant work can’t fix
In fairness, some problems need a different trade:
- Timber that has rotted
- Crumbling stone or brickwork round the window
- Planning or listed building consent (your local planning authority decides)
If you are not sure, just drop us a line at info@mrmastic.co.uk and we’ll give you a straight answer.

Common problems we fix in Braehoulland
Sand mastic slowly weathers. It hardens, cracks and starts to come away from the frame or the masonry.
Common reasons people contact us include:
- Weathered mastic on the most exposed windows
- Gaps where the frame meets the masonry
- Mastic round period door frames that has failed
- Tired mastic found when preparing windows for paint
In and around Braehoulland, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

Windows and doors in Braehoulland
Braehoulland 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. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
For jobs in and around Braehoulland, choosing the right material for each joint is as important as a tidy finish.

Leave it or put it right?
Cement-based fillers and modern sealants don’t always suit a period surround. Sand mastic is the like-for-like choice, which can matter on listed and conservation-area homes. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we’ll explain what it covers.

The process
Once we are on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours per window, depending on the condition of the joints. Outdoor work around Braehoulland depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic is not too thick.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Tell us about access, such as stairs, a lift or high-level joints
- Try not to wet indoor joints just before the visit
