Sand mastic in Portessie, done properly
Sand mastic doesn’t last for ever, leaving gaps round the window. Renewing it closes the gap and tidies the surround. We work on timber door frames, period & listed homes and stone surrounds, and common reasons people get in touch are patchy fillers round a sash window and gaps where the frame meets the masonry.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Exposed frames and sills take the full force of wind-driven rain.
You’re covered for a year from the day we finish. If anything isn’t right with it, email us at info@mrmastic.co.uk.

How the job changes by surface
Tenement and terrace windows
Where a building is shared, window work may involve neighbours, so check who is responsible first.
Period and listed homes
On a listed home or in a conservation area, the right material matters. Like-for-like sand mastic is normally favoured.
Why it’s worth doing now in Portessie
If you are redecorating, renew the mastic first. Painting over failed mastic does not seal it, and the new mastic is traditionally left unpainted. Around Portessie, water from a failed joint in an older stone home can soak into timber and plaster.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we’ll go through it with you.
Why book with us
- Arbo and Everbuild products
- Anti-fungal sanitary silicone in wet areas
- Any old sealant cut out fully, not covered over
- Fully insured
See our cost guide or our reviews.
The process
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours for a single window, longer for several and we leave things clean and tidy. Outside jobs in Portessie need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Preparing for the visit
- Clear the area around the work
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know if you’ve seen damp or leaks

When to call us in Portessie
Rain on the window surround works into any crack and pushes it out. Exposed elevations usually fail first.
Keep an eye out for these signs:
- Open joints round the window box
- Cracked mastic round a front door frame
- A silicone bead on a sash window that spoils the look
- Draughts and rain around sash boxes
Managing a site like Buckie High School? Then its window and door frames need their mastic kept sound, just like a home’s.

Portessie questions
Does the coastal weather in Portessie affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Is Portessie in your area for sand mastic?
Yes. Our work covers the whole of Scotland, and Portessie is part of that. Just email us at info@mrmastic.co.uk with a few details of the job.
What guarantee comes with the work?
Every job comes with our one-year guarantee, and we are fully insured.
What sealant do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Should I use sand mastic or silicone?
It depends on the window. Period windows in stone or brick usually suit sand mastic, while modern frames normally get a flexible sealant.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Can I add another job to the visit?
Yes. More than one area can go on one quote.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Avoid patching sand mastic with silicone
- Renew mastic before redecorating the windows
- Check with your local planning authority if your home is listed
- Check the mastic when you check the paintwork
When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.

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 the work is at height. Your quote takes all of that into account.

What else we do in Portessie
Frames and glazing around Portessie
Portessie 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. 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.
For an older house near a landmark such as St Peter's Church and Old Burial-Ground, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Portessie is about 1 mile north-east of Buckie, in Moray. Jobs in Portessie get the same care as everywhere else we work: old sealant removed completely, careful preparation and a one-year guarantee. Across Moray, we cover 58 places, Portessie among them. Our Aberdeen page covers work nearby.
