What happens if it’s left?
Working on frames from a ladder with a sealant gun is not easy, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, using a product chosen for the frame and wall. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

How we handle window mastic in Port Mholair
Mr Mastic’s applicators have more than 20 years’ experience with window and door sealants. We’re fully insured ARBOMaster approved applicators, and we give a one-year guarantee on the work. We work on window sills, composite doors and patio & French doors, and the jobs we see most are hard, cracked sealant around windows and untidy mastic left by window fitters.
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, so the mastic there works hard.
Your job is guaranteed for a year, as with all our work.

How the visit works
There isn’t much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes a morning for a couple of windows and a door from start to finish. Somewhere like Port Mholair may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely.
- The surfaces are cleaned and left dry.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- For indoor joints, keep the area dry beforehand if you can
- Clear items away from the joints we’re working on

Do you need window mastic in Port Mholair?
Joints that are too thin or too deep fail early. A skim of sealant over a wide gap soon tears, while a joint packed solid can’t stretch. That is what backing rod is for.
Signs it’s time to call us include:
- Hard, cracked sealant around windows
- White mastic on grey or black frames
- Draughts coming in around windows and doors
- Gaps where the sill meets the wall
Around Port Mholair, as everywhere, window mastic is only as good as the preparation behind it.

FAQs for Port Mholair
Does the coastal weather in Port Mholair affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Will you come out to Port Mholair?
Yes. Port Mholair is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland, including the islands, where work is planned around ferry crossings. Just mention lanes, gates or anything else about the route when you book.
Can you get sealant to suit coloured frames?
Yes, in most cases. Mention the frame colour when you ask for a quote and we’ll use the nearest match.
Can you seal the gap between the frame and the plaster indoors?
Yes, we do both. Inside, the joint between frame and plaster is sealed neatly, using a paintable sealant if you want to decorate.
Will the old sealant be removed?
Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Will new mastic stop draughts?
Yes, where the draught is at the frame edge. We find where the air is coming from before we reseal.
Can I add another job to the visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
What window mastic looks like in Port Mholair
Port Mholair 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 window and door frames, especially on the side facing the sea. Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
If you look after a building such as Aird Primary School, its window and door frames need their mastic kept sound, just like a home’s.
