Mount Vernon questions
Do you cover smaller places like Mount Vernon?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near Mount Vernon station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can email us at info@mrmastic.co.uk with the details for a clear quote.
Is it possible to take out silicone and use sand mastic instead?
Yes, it’s a common request. The old silicone has to come out completely so the mastic beds in well.
Should I check with the council before work on a listed or conservation-area home?
Check with your local planning authority. They decide whether consent is needed.
Can you seal over the old sealant?
No, it won’t last. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
What do you need from me for a quote?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply drop us a line at info@mrmastic.co.uk.
Are you insured?
Yes. We are fully insured for domestic and commercial work.
What’s sand mastic made of?
It’s a mix of sand and a linseed-oil-based binder. It’s built up in the joint by hand and shaped to suit the surround.
How we handle sand mastic in Mount Vernon
Old sand mastic cracks, crumbles and falls out over time, leaving gaps round the window. Renewing it closes the gap so the surround looks right again. We work on sash and case windows, stone surrounds and period & listed homes, and the jobs we see most are patchy fillers round a sash window and modern sealant on a period surround.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What we do, step by step
We keep the work tidy and contained to the area we are working on. Expect the work to take anything from a few hours to a full day, depending on how many windows, and we explain the cure time before we leave. Outdoor work around Mount Vernon depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Tell us about any previous sealing or DIY attempts
- Try not to wet indoor joints just before the visit

Do you need sand mastic in Mount Vernon?
Decorating can disturb tired mastic. It’s often found when windows are being prepared for paint, which is a good time to renew it.
Common reasons people contact us include:
- Old sand mastic that has cracked, crumbled or fallen out
- Tired mastic found when preparing windows for paint
- Cement or filler used on old window joints that has cracked
- A silicone bead on a sash window that spoils the look
If you look after a building such as Carmyle Primary School, the mastic around its windows and doors needs looking after like any other building’s.

Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic. With historic houses such as Provand's Lordship (about 3.9 miles west) nearby, there’s older building stock in the area around Mount Vernon as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.

Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Keep sills and gutters clear so water drains away
- Have rotten timber repaired before new mastic goes in
- Go gently near the mastic when preparing windows
- Keep modern sealant off the mastic
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens as more mastic falls out.
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
