Sand mastic for homes and businesses in Corpach
Sand mastic skins over fairly quickly, but it takes longer to harden fully. Traditionally, sand mastic is left unpainted, so ask us before you decorate. Common call-outs are for silicone on a period window that looks wrong and crumbling sand mastic round a window, across period & listed homes, brick reveals and timber door frames.
Many older Scottish homes still have timber windows set into stone walls. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.

What sand mastic looks like in Corpach
Corpach is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
If you let a flat or house near Corpach station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

How it works
The work is kept neat and contained to the joints we’re treating, so you can carry on as normal. The job normally takes anything from a few hours to a full day, depending on how many windows, and we explain the cure time before we leave. In smaller Scottish places, parking is generally less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We check the window surrounds and agree which joints need renewing.
- Old, loose mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
Getting ready for the visit
- Clear the area around the work
- Plan for the work area to be out of bounds to pets and children
- Mention any leaks or damp you’ve noticed

Advice
Corpach questions
Can you help a landlord with a rental near Corpach station?
Yes, rental work is part of what we do. Just email us at info@mrmastic.co.uk and tell us about the property, and we’ll give you a clear quote.
Is Corpach within the area you cover?
Yes. Corpach is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Do I need permission for sand mastic on a listed building?
Check with your local planning authority. They’ll tell you if consent is needed.
How long does sand mastic take to harden?
A skin forms quite soon, but full hardening takes longer. We’ll tell you what to expect for your job.
Do you hold any approvals?
Yes. We’re approved under the ARBOMaster scheme.
Can you seal over the old sealant?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. We remove it all first.
What do you need from me for a quote?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply email us at info@mrmastic.co.uk.
Can sand mastic be painted?
The usual advice is to leave sand mastic unpainted. If you’re redecorating the window, ask us first and we’ll advise.

Common problems we fix in Corpach
Over the years, sand mastic weathers. It hardens, cracks and starts to come away from the frame or the masonry.
Common reasons people contact us are:
- Gaps between timber frames and stone or brick
- Cracked mastic round a front door frame
- Patchy fillers round a sash window
- Modern sealant on a period surround
If you look after a building such as Lochaber High School, the mastic around its windows and doors needs looking after like any other building’s.

Aftercare tips
So the new joints stay in good condition:
- Ask the planning authority about consent for listed or conservation-area homes
- Have rotten timber repaired before new mastic goes in
- Renew mastic before redecorating the windows
- Inspect the joints round the windows every year or so
Avoid painting over the new mastic, which is the traditional advice. Ask us before any decorating around it.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.
What the job involves on each surface
Stone surrounds
Sand mastic sits naturally against stone. It finishes to look like part of the surround.
Period and listed homes
Many older homes were built with sand mastic round the windows. If your home is listed, ask your local planning authority about consent.
For landlords and businesses
For anyone letting property in or around Corpach, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs, and photos by email help.
In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
When something else is needed
Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Planning or listed building consent (your local planning authority decides)
- Damaged stone surrounds
- Cracked or broken glass
If you are not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer before booking.
