Window mastic in Ardheisker
Most frames have an outside joint and an inside one. The external joint is the weather seal; the internal joint closes the gap to the plaster and stops draughts. We seal one or both, depending on what’s needed. Typical jobs include water coming in at the bottom corners of a door and old mastic that has gone black or come away, across uPVC windows, composite doors and aluminium frames.
Outdoor sealant needs a dry surface, so window work around Ardheisker is planned around the weather. Let us know about access to every frame, including any upstairs.
You get a 12-month guarantee, the same in Ardheisker as everywhere else we work.

Windows and doors in Ardheisker
Ardheisker 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 window and door frames, especially on the side facing the sea. Ardheisker is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for the mastic around window and door frames to keep out.
For jobs in and around Ardheisker, choosing the right material for each joint is as important as a tidy finish. In and around Ardheisker, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

Patio & French doors
Heavy door frames can move more than windows. A flexible sealant copes with that without cracking.
uPVC windows
We clean the frame edge carefully so the plastic is not marked, then the sealant goes in between frame and wall.

Leave it or put it right?
If you’re painting or rendering, reseal at the same time. Fresh joints finish the job neatly, and it’s easier while the walls are being worked on anyway. In a place like Ardheisker, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first and give you a clear price before we start.
Why us?
- A 12-month guarantee on all work
- We never seal over old sealant
- You choose the colour before work begins

Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Make sure the drainage slots are not blocked
- Ventilate rooms so frames don’t stay wet inside
- Keep paint and stain on wooden frames in good order
- Paint up to the joint, not over it
Keep sill grooves and drainage slots clear, so rain drains out rather than building up at the sealant.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. Resealing closes it.
FAQs for Ardheisker
Is window mastic in a coastal place like Ardheisker any different?
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 Ardheisker in your area for window mastic?
Yes. We work across all of Scotland, and Ardheisker is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job.
Can tenants book the work?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Can you seal the gap between the frame and the plaster indoors?
Yes. Draughts often come through the inside gap too, so sealing both is often worthwhile.
Are you fully insured?
Yes, we’re fully insured for every job we do.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Where is Mr Mastic based?
We’re based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Do you guarantee window mastic?
Yes. All our work carries a 12-month guarantee, and we’re fully insured.

Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
