Sand mastic in Brough, done properly
We renew sand mastic around sash windows and doors set in stone or brick. The old mastic is raked out, and new mastic is applied and shaped by hand. We work on period & listed homes, tenement windows and sash and case windows, and the jobs we see most are mastic worn away on windows facing the weather and gaps where the frame meets the masonry.
In and around a place like Brough, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.
Your job is guaranteed for a year, as with all our work.

What happens if it’s left?
Before painting the windows, it pays to renew the mastic. Painting over failed mastic doesn’t seal it and traditional guidance is to leave the new mastic unpainted. In an older home around Brough, damp from a failed joint can get into timber and plaster.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

When to call us in Brough
Paint, silicone or cement used over old mastic causes problems. They do not move with the timber and we normally remove them.
These are the problems we are asked about most:
- Gaps between timber frames and stone or brick
- Modern sealant on a period surround
- Mastic worn away on windows facing the weather
- Crumbling sand mastic round a window
Around Brough, as everywhere, sand mastic is only as good as the preparation behind it.

Your questions about sand mastic in Brough
Does living near the coast affect sand mastic in Brough?
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 generally the first to need attention.
Do you cover Brough for sand mastic?
Yes. Our work covers the whole of Scotland, and Brough is part of that. Just email us at info@mrmastic.co.uk with a few details of the job, and we will give you a clear quote.
Is sand mastic better than silicone for my windows?
That depends on your windows. Period windows in stone or brick usually suit sand mastic, while modern frames normally get a flexible sealant.
Do you guarantee sand mastic work?
Our 12-month guarantee applies on every job.
How long does sand mastic take to go off?
It forms a skin fairly soon, then hardens over a longer period. The weather and joint depth both affect it.
Do I need permission for sand mastic on a listed building?
Checking first is sensible. Ask your local planning authority whether consent is needed for listed or conservation-area properties.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us, and we are fully insured.
Is it possible to take out silicone and use sand mastic instead?
In most cases. We remove the silicone and clean the joint, then point it with sand mastic.
Landlords, agents and businesses in Brough
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Aftercare tips
Good habits help new joints last longer. Our tips:
- Make sure water runs off the sill
- Plan mastic work ahead of painting
- Don’t run silicone over sand mastic
- Inspect the joints round the windows every year or so
Avoid painting over the new mastic, as traditional guidance advises. If you’re redecorating, ask us first.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.
Can I do it myself?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
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.
Sand mastic in Brough: local notes
Brough 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 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, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
Castle of Mey, about 4.8 miles east, is one of the historic houses in the wider area around Brough, and older homes nearby need a sealant that suits their walls.
Brough is about 7 miles north-east of Thurso, in Highland. Jobs in Brough get the same care as everywhere else we work: old sealant removed completely, careful preparation and a one-year guarantee. Our area takes in 253 places across Highland, from the larger towns to small villages.

Let us know how to find you and how to reach the joints.
- We start by checking each surround and agreeing the joints to renew.
- The loose and crumbling 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.
