Sand mastic for homes and businesses in Armadale
Burnt sand mastic is a traditional material blends with stone and brick surrounds. It’s a good fit for period properties where a modern sealant bead would stand out. Typical jobs include cement or filler used on old window joints that has cracked and mastic that needs renewing before redecorating, across period & listed homes, timber door frames and stone surrounds.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
All of our work is guaranteed for twelve months.

Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- Large voids are packed out first, so the mastic isn’t too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.

Armadale: your questions answered
Will you come out to Armadale?
Yes, Armadale is covered. We work across all of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Armadale station?
Yes, we work for landlords and letting agents. You can send an email to info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before work begins.
Is the work guaranteed?
Every job comes with our one-year guarantee.
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 listed or conservation-area properties.
How long does the job take?
As a guide, most jobs take anything from a few hours to a full day, depending on how many windows. Larger jobs naturally take longer.
Can you replace silicone on a period window with sand mastic?
Usually, yes. With the silicone removed and the joint cleaned, sand mastic is applied by hand.
Will there be a smell?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
Are you insured?
Yes. We’re fully insured, and we can confirm the details when we quote.
What affects the cost of sand mastic
The price is agreed before any work begins. It’s based on:
- Whether there’s mould to deal with
- Whether the work is at height
- Working hours on commercial sites
- How much old sealant there is and how hard it is to remove
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and send you a clear quote before work begins.
What to tell us for a quote
Before you ask for a quote, have a think about:
- If someone has resealed it before
- If it’s domestic, commercial or a hotel
- Where the property is
- Pictures of the joints, sent by email

Why deal with it now?
Filling over old, loose mastic does not last. Raking out and preparing the joint gives it a sound base so the new work lasts. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, drop us a line at info@mrmastic.co.uk for an honest opinion and a quote.

These are the problems we’re asked about most:
- Crumbling sand mastic round a window
- Silicone on a period window that looks wrong
- Gaps between timber frames and stone or brick
- Mastic worn away on windows facing the weather
If you let a flat or house near Armadale station, any sash windows need sound mastic to keep draughts and rain out.

Aftercare tips
Aftercare is simple:
- Renew mastic before redecorating the windows
- Clear gutters so water doesn’t pour onto the windows
- Check with your local planning authority if your home is listed
- Do not run silicone over sand mastic
Don’t touch or press the mastic while it hardens. It forms a skin fairly soon, but takes longer to harden fully.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.
