Sand mastic for homes and businesses in Kilmuir
On many period windows, sand mastic looks right and suits the building. Newer frames normally get a flexible sealant instead and we’ll explain which is best for yours. If you have gaps round a timber door in stone or brick and mastic dropping out of the joint, we can help, whatever the surface.
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.
Every job is covered by our 12-month guarantee, wherever you are in Highland.

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.
Tenement and terrace windows
Windows above ground floor need the right access. Let us know the floor and we’ll confirm access.
Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Don’t paint over the new mastic
- Go gently near the mastic when preparing windows
- Sort the mastic before the decorators arrive
- Check with your local planning authority if your home is listed
Don’t touch or press the mastic while it hardens. It skins over quickly but needs longer to fully harden.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens.
Why deal with it now?
Draughts round a sash window aren’t always the sashes. Open mastic joints round the box can let air in and new mastic seals them. Around Kilmuir, water from a failed joint in an older stone home can soak into timber and plaster.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first.

Your questions about sand mastic in Kilmuir
Do you work for landlords with property near Invergordon station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can email us at info@mrmastic.co.uk with the details for a clear quote.
Do you cover smaller places like Kilmuir?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Is it OK to seal over old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
Will there be a smell?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
Can old silicone round a sash window be swapped for sand mastic?
In most cases. The silicone is cut out and the joint cleaned, then point it with sand mastic.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
How do I get a quote for sand mastic in Kilmuir?

Frames and glazing around Kilmuir
Kilmuir is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.
If you let a flat or house near Invergordon station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

- Cracked mastic round a front door frame
- Mastic that needs renewing before redecorating
- Crumbling sand mastic round a window
- Patchy fillers round a sash window
If you live in an older home near Parish Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
