About our sand mastic in Ardentinny
We work across Ardentinny renewing sand mastic on sash windows and doors. Every joint is cleaned out and filled by hand, finished to suit the masonry. Typical jobs include tired mastic found when preparing windows for paint and old cement repairs round a window that have failed, across sash and case windows, brick reveals and tenement windows.
Mastic can only go onto a dry joint, so outside work in Ardentinny depends on the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
We stand behind the work with a 12-month guarantee, so you are covered after we’ve gone.

What sand mastic looks like in Ardentinny
Ardentinny is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. 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.

DIY sealant or a professional job?
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.
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.
Ardentinny: your questions answered
Does living near the coast affect sand mastic in Ardentinny?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Can you help a landlord with a rental near Garelochhead station?
Yes, we work for landlords and agents. You can drop us a line at info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before work begins.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned.
What do you need from me for a quote?
A short description and the location, with pictures by email if possible. If we need more, we’ll ask.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
When will the new mastic be hard?
The surface skins quite quickly and it hardens fully over a longer time. Timing depends on the weather and the joint.
Can you seal over the old sealant?
No, because it fails. We remove every bit of old sealant first, so the new sealant bonds properly.
Can you replace silicone on a period window with sand mastic?
Yes, it’s a common request. The old silicone has to come out completely so the mastic beds in well.

How we quote for sand mastic
There’s no set price list, because jobs vary so much. What we look at:
- Any working-time requirements on site
- Whether there’s mould to deal with
- The size of the job
- Access and height
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and agree the price before starting.
Helping us quote
Photos help, but a description is a good start. Try to tell us:
- The rough size of the job
- Any previous sealing or DIY work
- If it’s domestic, commercial or a hotel
- What’s wrong with the joints now
To get a quote, drop us a line at info@mrmastic.co.uk and tell us where the job is and what the problem looks like. We’ll send you a clear quote before any work starts.
Leave it or put it right?
If you’re redecorating, renew the mastic first. Paint over cracked mastic won’t stop the gaps and traditional guidance is to leave the new mastic unpainted. In an older home around Ardentinny, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we will go through it with you.

Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Ask us before painting near the mastic
- Avoid patching sand mastic with silicone
- Look over the window mastic once a year
- Renew mastic before redecorating the windows
Avoid painting over the new mastic, as traditional guidance advises. Ask us before any decorating around it.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.

What we’re called out for in Ardentinny
Age is the main cause. Even well-laid mastic needs renewing in time and how long it lasts depends on the weather it faces.
The problems people usually mention when they call include:
- Mastic that needs renewing before redecorating
- A silicone bead on a sash window that spoils the look
- Gaps round a timber door in stone or brick
- Cement or filler used on old window joints that has cracked
If you live in an older home near Ardentinny Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
