You’ll get a clear quote before we start. It’s based on:
- The size of the job
- Whether old sealant or filler has to be cut out

How we handle sand mastic in Gartloch
Across Gartloch, we renew sand mastic around sash and case windows. Each joint is raked out, prepared and pointed by hand for a neat, traditional finish. If you have silicone on a period window that looks wrong and mastic that needs renewing before redecorating, we can help.
Mastic can only go onto a dry joint, so outside work in Gartloch depends on the weather. Tell us about access to all the windows and doors, upstairs included.
All our work comes with a one-year guarantee, wherever you are in Glasgow.

What happens if it’s left?
Replacing sash windows is a big decision for a period home, and in listed buildings it may need consent. Where the frames are in good order, new mastic seals the surround. Around Gartloch, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
We don’t show prices on the website, because each job is priced on what it involves. For a quick quote, please drop us a line at info@mrmastic.co.uk and we’ll talk you through it.

Gartloch: your questions answered
Do you cover smaller places like Gartloch?

Is Gartloch in your area for sand mastic?
Yes. We work across all of Scotland, and Gartloch is part of that. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing.
Can I choose the sealant colour?
We will suggest a colour to suit the surroundings, from white and clear to greys and other shades. The product needed can limit the range.
Do you work for letting agents?
Yes. We work for householders, landlords, letting agents, businesses and hotels across Glasgow.
How long does sand mastic take?
Typically it takes anything from a few hours to a full day, depending on how many windows. Larger jobs naturally take longer.
Will it make a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Do you remove the old sealant?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Can you seal over the old sealant?
No, because it fails. We remove every bit of old sealant first.
Gartloch homes and the weather
Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
Letting a property close to Gartcosh station? Then older sash windows in a rental need their mastic kept sound to keep the weather out. If you live in an older home near Saint Benedict's Church, the joint between an old wall and a newer frame is normally the first place rain gets in.

Aftercare tips
Aftercare is simple:
- Get any rot dealt with first
- Ask the planning authority about consent for listed or conservation-area homes
- Look over the window mastic once a year
- Avoid heavy scraping on the mastic joint
Leave the new mastic unpainted, which is the traditional advice. If you’re redecorating, ask us first.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
