Sand mastic in Galltair
Our applicators renew the sand mastic around sash and case windows and doors set in stone or brick. The old mastic is raked out, the joint is prepared and new mastic is shaped by hand. If you have a silicone bead on a sash window that spoils the look and gaps where the frame meets the masonry, we can put it right.
In and around a place like Galltair, 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.
All our work comes with our 12-month guarantee, wherever you are in Highland.

What affects the cost of sand mastic
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Any working-time requirements on site
- Any mould that needs treating
- The number and length of the joints
- The number of rooms or windows
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, drop us a line at info@mrmastic.co.uk for an honest opinion and a quote.
Helping us quote
Photos help, but a description is a good start. Please mention:
- Whether it’s a home or a business
- If someone has resealed it before
- How we’d reach the joints
- Photos by email, if that’s easy
We don’t publish a price list, as no two jobs are quite the same. Instead, we give you a clear quote for your job. To arrange one, send an email to info@mrmastic.co.uk.
What we can’t put right
Some problems need a builder, plumber or other trade rather than us:
- Timber that has rotted
- Cracked or broken glass
- Whether work needs listed building consent
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we will tell you honestly before booking.
What we seal
- Timber door frames
- Brick reveals
- Period & listed homes
- Stone surrounds
- Sash and case windows
- Tenement windows
What happens if it’s left?
Draughts round a sash window are not always the sashes. Gaps between the frame and the wall can be just as bad, and renewing the mastic closes them. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

Signs you need sand mastic in Galltair
Timber swells and shrinks with the weather. That movement opens up the mastic joint little by little.
Keep an eye out for these signs:
- Gaps where the frame meets the masonry
- Mastic that needs renewing before redecorating
- Mastic round period door frames that has failed
- Wind and rain getting in round a sash window
Managing a site like Bernera School? Then its window and door frames need their mastic kept sound, just like a home’s.

Advice
Sand mastic in Galltair: local notes
Galltair 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 is 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.
Around Galltair, as everywhere, sand mastic is only as good as the preparation behind it.

Galltair questions
Is sand mastic in a coastal place like Galltair any different?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. Walls facing the sea are generally the first to need attention.
Do you cover smaller places like Galltair?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Should I use sand mastic or silicone?
Sand mastic normally suits period timber windows best. On modern frames, we’d normally use a flexible sealant, and we will explain why.
Do you remove the old sealant?
Yes, every time. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Do you have insurance?
Yes. We are fully insured, and we have been doing sealant work for more than 20 years.
Is it messy?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will explain our choice.
Can sand mastic be painted?
Traditional guidance is not to paint over sand mastic. Ask us before you decorate around it and we’ll advise.

Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
