Landlord and commercial work in Kilmun

Glazing silicone in Kilmun, done properly
We work across Kilmun on glazing joints for homes and businesses. Conservatories, rooflights, glass panels and shower screens are all part of the job, with a sealant chosen for the joint. Typical jobs include water tracking down the inner face of the glass and conservatory leaks at frame and glazing joints, on glass balustrade bases, glass-to-glass joints and shower screens.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
There’s a 12-month guarantee on every job, whatever its size.

What happens on the day
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself usually takes a few hours, depending on how many joints need doing, depending on the size of the job. Outside jobs in Kilmun need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We look at the glazing and agree which joints need resealing.
- We cut away the failed silicone.
- We clean and prepare the joint.
- We apply and tool the new silicone.
- The joints are checked before we leave.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Mention any tricky access
- Keep pets and children clear of the area while we work

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
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.

Frames and glazing around Kilmun
Kilmun is within about 1 mile of 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 glazing joints and frame seals, which can dry out and crack sooner where a building faces the weather. Kilmun is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for glazing joints and frame seals to keep out.
For site and facilities teams at buildings such as Dunoon Grammar School, its window and door frames need their mastic kept sound, just like a home’s. In the older streets around St Munn's Parish Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Kilmun questions
Does the coastal weather in Kilmun affect outside sealant?
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.
Do you cover smaller places like Kilmun?
Yes. Kilmun is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Where do you work from?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Can I choose the sealant colour?
Most of the time, yes. We will explain which colours are available.
Is it enough to run a bead over the old sealant?
New silicone won’t bond to old silicone and water gets between the layers. The old bead always comes out first.
How long before the joint can be used?
It depends on the product and the conditions. We tell you how long to leave it before we go.
How long does glazing silicone take?
That depends on how much there is to do, but most jobs take anything from an hour or two to most of a day, depending on the size of the job. We’ll tell you when we quote.
Is it worth trying it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Why it’s worth doing now in Kilmun
If the problem is a misted unit or a broken panel, sealant won’t help. We say so plainly, so you can call the right trade. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
We don’t show prices on the website, because each job is priced on what it involves. For a quick quote, please drop us a line at info@mrmastic.co.uk.

Aftercare tips
So the new joints stay in good condition:
- Keep harsh solvents off the silicone
- Open vents or windows to let moisture out
- Inspect the sealant on glazing annually
- Avoid scraping close to the bead
Keep the new joints dry for as long as we advise. After that, clean glass with a mild cleaner.
If silicone on glass has cracked, water is already getting in. Renewing it early keeps it simple compared with fixing water damage later.
