Glen More: your questions answered
Is sand mastic in a coastal place like Glen More any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Can you do sand mastic in Glen More?
Yes. Our work covers the whole of Scotland, and Glen More is part of that. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Do the sealants smell?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
Is it OK to seal over old sealant?
No, it will not last. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Do you offer different sealant colours?
We help you choose a colour that suits. The choice depends on the product the joint needs.
Do you hold any approvals?
Yes. We’re approved under the ARBOMaster scheme.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Sand mastic for homes and businesses in Glen More
Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. Renewing it closes the gap so the surround looks right again. We work on timber door frames, sash and case windows and stone surrounds, and people most often call us about old cement repairs round a window that have failed and gaps round a timber door in stone or brick.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
We stand behind the work with a one-year guarantee, so you’re not left on your own once the job is done.

What we are called out for in Glen More
Age is the main cause. Even well-laid mastic needs renewing in time and how long it lasts depends on the weather it faces.
Look out for any of the following:
- Crumbling sand mastic round a window
- Draughts and rain around sash boxes
- Failed mastic on an exposed elevation
- Open joints round the window box
Around Glen More, as everywhere, sand mastic is only as good as the preparation behind it.

What affects the cost of sand mastic
There’s no set price list, because jobs vary so much. What we look at:
- Whether there’s mould to deal with
- The size of the job
- How easy the joints are to reach
- The type of sealant required
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we’ll explain what it covers.
Asking for a quote
There’s no need for technical detail. It helps if you can tell us:
- A few photos by email, if you can
- The address or postcode of the job
- Any previous sealing or DIY work
- How we’d reach the joints
For a quick quote, get us on the phone, or send an email if you’d rather. Describe what needs sealing and we will explain what’s involved and give you a clear quote.

What happens if it’s left?
New mastic over crumbling mastic will not hold. Raking out and preparing the joint gives it a sound base so the new mastic stays put. Around Glen More, 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.
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, email us at info@mrmastic.co.uk for an honest opinion and a quote.
What you get with us
- A 12-month guarantee on all work
- Homes, businesses and hotels
- Any old sealant cut out fully, not covered over
- Fully insured

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Frames and glazing around Glen More
Glen More is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around older windows and doors, especially on the side facing the sea. Glen More is in the west of Scotland, which is wetter than the east, which means the mastic around older windows and doors has to cope with a lot of rain.
Whether the job is in Glen More itself or nearby, the right material for each joint matters as much as a neat finish.
