About our window mastic in Glenelg
Every window and door frame has a gap around it, and mastic is what closes it. When it cracks, hardens or pulls away, draughts and rain get in. The old mastic is removed and the joint resealed with a flexible exterior sealant. We work on aluminium frames, composite doors and window sills, and people most often call us about draughty joints inside around the window and rain getting in at the frame or under the sill.
Outdoor sealant needs a dry surface, so window work around Glenelg is planned around the weather. Tell us about access to all the windows and doors, upstairs included.
Your job is guaranteed for a year, as with all our work.

Honest limits
In fairness, there are a few things sealant won’t fix:
- A frame that has rotted at the joint
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Worn gaskets, brush seals or a door that has dropped
If you’re not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer.

DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
What happens if it’s left?
Working on frames from a ladder with a sealant gun is not easy, especially upstairs. A professional job is cut out properly, backed where needed and finished 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.
Combining jobs into one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. We will send you a clear quote for the lot.

What we do, step by step

- We check each frame and agree which ones need doing.
- The old mastic is cut out and the surfaces cleaned back.
- Where gaps are deep, backing rod goes in first.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- We clear up and check every joint is fully closed.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Keep pets and children clear of the area while we work
- Mention any sign-in or site rules at work premises

Related advice
Your questions about window mastic in Glenelg
Do you cover smaller places like Glenelg?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Is window mastic in a coastal place like Glenelg any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint before we leave.
Can you seal the gap between the frame and the plaster indoors?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We do one or both.
Can you get sealant to suit coloured frames?
Yes, we choose a colour to suit the frame. Anthracite grey, black, brown and white cover most frames, with clear as an option.
Can new sealant go over the old?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
Can you reach windows above the ground floor?
Yes, as long as they can be reached safely. Let us know about access when you ask for a quote and we’ll plan for it.
Are you fully insured?
Yes. We are fully insured, and we have been doing sealant work for more than 20 years.
Common problems we fix in Glenelg
Mastic ages in the weather. Sunlight dries the surface out, until it loses its stretch and starts to crack.
The problems people usually mention when they call include:
- Sealant in the wrong colour for the frame
- Gaps between the frame and the inside reveal
- Gaps left after new windows were fitted
- Damp patches on the reveal after heavy rain
Around Glenelg, as everywhere, window mastic is only as good as the preparation behind it.

Frames and glazing around Glenelg
Glenelg is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. The west of Scotland is wetter than the east, which means the mastic around window and door frames has to cope with a lot of rain.
Schools such as Bernera School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
