About our sand mastic in Smyrton
Sand mastic doesn’t last for ever, leaving gaps round the window. We rake it out and renew it so the surround looks right again. Typical jobs include cement or filler used on old window joints that has cracked and wind and rain getting in round a sash window, across timber door frames, sash and case windows and stone surrounds.
In and around a place like Smyrton, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.
Whatever the size of the job, you get the same one-year guarantee.

Common problems we fix in Smyrton
Scraping and sanding before painting can loosen old mastic. It’s often found when windows are being prepared for paint, which is a good time to renew it.
If you can see any of these, it’s time to have the joints looked at:
- Gaps round a timber door in stone or brick
- Weathered mastic on the most exposed windows
- Old cement repairs round a window that have failed
- Window mastic to renew ahead of painting
Around Smyrton, as everywhere, sand mastic is only as good as the preparation behind it.
Before booking anyone
- Who turns up on the day
- Whether you can choose the colour
- Whether the sealant suits the joint
- What guarantee comes with the work
What happens if it’s left?
If you are redecorating, renew the mastic first. Paint over cracked mastic won’t stop the gaps, and the new mastic is traditionally left unpainted. 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 guesswork. That is why we ask about the job first.

Questions from Smyrton
Will you come out to Smyrton?
Yes. Smyrton is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Can you do sand mastic in Smyrton?
Yes. We work across all of Scotland, and Smyrton is part of that. You can email us at info@mrmastic.co.uk and let us know what needs doing, and we’ll give you a clear quote.
Can old silicone round a sash window be swapped for sand mastic?
Yes. The silicone is cut out and the joint cleaned before the sand mastic goes in.
Do you work for letting agents?
Yes, regularly. We can quote for several properties at once, and between tenancies is a good time for the work.
How long does sand mastic take?
Most jobs take a few hours for a single window, longer for several, including preparation and clearing up. We’ll confirm how long when we quote.
Does someone need to be in?
We need access to the joints, so we will agree that with you when we book. Indoors, that generally means someone at home.
Do I need permission for sand mastic on a listed building?
It’s best to ask your local planning authority first. Like-for-like sand mastic is often the preferred finish but the decision is theirs.
Is it worth trying it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
A careful DIYer can reseal a simple joint, 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.
How we quote for sand mastic
The quote reflects the job in front of us. We take into account:
- Any working-time requirements on site
- How many rooms, windows or areas are involved
- Whether the work is at height
- How much there is to do
The cost depends on the size of the job, how much old material has to come out and access to the work. You will have a clear quote before any work starts.
Asking for a quote
To help us quote quickly, please include:
- A few pictures by email, if you can
- Any access issues, like height or stairs
- Whether it has been sealed before
- The type of property
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add pictures by email if you can.
What we do, step by step
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. It usually takes a few hours for a single window, longer for several. Somewhere like Smyrton may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- For business premises, tell us about site rules or sign-in
- For indoor joints, keep the area dry beforehand if you can

What sealant work can’t fix
To be straight with you, there are a few things sealant will not fix:
- Broken panes
- Sash cords, weights and draught-proofing of the sashes
- Rotten sashes, sills or window boxes (a joiner’s job)
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we will tell you honestly before booking.
Joints and surfaces we work on
- Tenement windows
- Timber door frames
- Sash and case windows
- Period & listed homes
- Stone surrounds
- Brick reveals
Keeping the joints in good condition
So the new joints stay in good condition:
- Have rotten timber repaired before new mastic goes in
- Avoid patching sand mastic with silicone
- Take care around the mastic when scraping paint
- Look over the window mastic once a year
When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry so early renewal protects both.
Sand mastic in Smyrton: local notes
Smyrton is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around older windows and doors, especially on the side facing the sea. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
Whether the job is in Smyrton itself or nearby, the right material for each joint matters as much as a neat finish.
