Sand mastic for sash & case windows in Whiterow, Highland
Professional sand mastic in and around Whiterow, with old sealant always removed completely.
- Tired mastic found when preparing windows for paint
- Mastic worn away on windows facing the weather
- Mastic dropping out of the joint
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Clear gutters so water does not pour onto the windows
- Ask the planning authority about consent for listed or conservation-area homes
- Don’t run silicone over sand mastic
- Do not paint over the new mastic
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber, which can lead to rot.
Sand mastic in Whiterow, done properly
Sand mastic skins over fairly quickly but full hardening takes longer. Traditional guidance is not to paint over it, so ask us before you decorate. We work on period & listed homes, timber door frames and stone surrounds, and common reasons people get in touch are old sand mastic that has cracked, crumbled or fallen out and mastic round period door frames that has failed.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
There’s a 12-month guarantee on every job, large or small.

What sand mastic looks like in Whiterow
Whiterow is within about 1 mile of 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. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
If you live in an older home near Pulteneytown Parish Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Schools such as Wick High School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

Your questions about sand mastic in Whiterow
Is sand mastic in a coastal place like Whiterow 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 work for landlords with property near Wick station?
Yes. We work for letting agents and landlords as well as homeowners. You can send an email to info@mrmastic.co.uk with the details for a clear quote.
How much does sand mastic cost in Whiterow?
It depends on the job, so we quote each one individually. To get one, send an email to info@mrmastic.co.uk and let us know what needs doing and where.
Can I add another job to the visit?
Yes. Just list everything you need and we’ll quote it together.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Do I need permission for sand mastic on a listed building?
Yes, it’s worth checking. Ask your local planning authority whether consent is needed for work on a listed home or in a conservation area.
Will there be a smell?
Possibly a little. It fades as the sealant cures, and ventilation helps.
Do you guarantee sand mastic work?
You get our one-year guarantee on every job.

Common problems we fix in Whiterow
Over the years, sand mastic weathers. It hardens, cracks and starts to come away on the stone or timber.
Any of these means the joints need attention:
- A silicone bead on a sash window that spoils the look
- Tired mastic found when preparing windows for paint
- Cracked mastic round a front door frame
- Open joints round the window box
For landlords with property near Wick station, any sash windows need sound mastic to keep draughts and rain out.
Questions to ask before you book
- Whether you can choose the colour
- How the joint is cleaned and prepared
- What the quote includes, VAT included or not
- What the cure time is
Different surfaces, different methods
Sash and case windows
The box of a sash and case window sits in the stone or brick opening. Sand mastic seals the joint round it.
Brick reveals
An open joint at a brick reveal lets weather in. Renewing the mastic closes it.
Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
When it isn’t the sealant
We’d rather tell you now than do work that will not last, so here’s what sealant can’t put right:
- Cracked or broken glass
- Whether work needs listed building consent
- Timber that has rotted
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly before booking.

What happens on the day
You do not need to clear the whole room or building, only the area right around the joints. We protect the rest, and the work takes anything from a few hours to a full day, depending on how many windows in most cases. 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.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic is not too thick.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Clear the area around the work
- Mention any tricky access
