Sand mastic for homes and businesses in Blairmore
A silicone bead around a sash window can look out of place and isn’t always the right material. Sand mastic gives a finish that matches the age of the house and we can swap the silicone for it. If you’re dealing with gaps round a timber door in stone or brick and failed mastic on an exposed elevation, we can put it right.
In and around a place like Blairmore, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill, so the mastic there works hard.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

How it works
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take anything from a few hours to a full day, depending on how many windows. For a place like Blairmore, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- We check the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.
- 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.
How to prepare
- Keep pets and children clear of the area while we work
- For business premises, tell us about site rules or sign-in
- Mention any leaks or damp you’ve noticed

Why it’s worth doing now in Blairmore
Filling over old, loose mastic does not last. We remove the loose material first 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.
We do not show prices on the website, because each job is priced on what it involves. Call for a quick quote.

What sand mastic looks like in Blairmore
Blairmore is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around older windows and doors, especially on the side facing the sea. The west of Scotland is wetter than the east, so there’s plenty of rain for the mastic around older windows and doors to keep out.
Homes close to Strone Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you let a flat or house near Gourock station, any sash windows need sound mastic to keep draughts and rain out.

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.

No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part.

FAQs for Blairmore
Is sand mastic in a coastal place like Blairmore any different?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are normally the first to need attention.
Do you cover smaller places like Blairmore?
Yes, Blairmore is covered. Our work covers the whole of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you take out the old sealant first?
Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.
Will it make a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
How do I get a quote for sand mastic in Blairmore?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You will get a clear quote before any work starts.
Is sand mastic better than silicone for my windows?
For period timber windows in stone or brick, sand mastic is often the better fit. Modern frames normally suit a flexible sealant.
Can I choose the sealant colour?
In most cases you can choose. We will tell you which colours the right product comes in.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.

Period and listed homes
A traditional finish suits a period property, and sand mastic is one of them.
Brick reveals
We rake out the old mastic and pack deep voids before the new mastic goes in.
DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Aftercare tips
To keep the joints looking good and working properly:
- Avoid heavy scraping on the mastic joint
- Plan mastic work ahead of painting
- Get any rot dealt with first
- Don’t run silicone over sand mastic
Leave the new mastic unpainted, as traditional guidance advises. Ask us before any decorating around it.
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.
