How we handle glazing silicone in Dunoon
We work across Dunoon 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. We’re often asked to deal with water tracking down the inner face of the glass and mouldy sealant around glass panels, across shower screens, conservatory frames and glass-to-glass joints.
In and around a place like Dunoon, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

How it works
When we arrive, we start by going over the job with you, so you know exactly what we’re doing. We protect the surfaces around the joints before any work begins. The work usually takes anything from an hour or two to most of a day, depending on the size of the job. In smaller Scottish places, parking is generally less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- First we agree the joints to be done.
- Old sealant is removed from the glass and frame.
- The surfaces are cleaned with a suitable solvent.
- We apply and tool the new silicone.
- The joints are checked before we leave.
How to prepare
- Mention any leaks or damp you’ve noticed
- Keep children and pets away from the work area
- Move anything stored near the joints

Surface by surface
Shower screens
Most shower screen leaks come from the wall or tray joint. We reseal both with anti-fungal silicone.
Conservatory frames
Conservatory frame joints are a common source of leaks. We cut out the old sealant and reseal.
Dunoon homes and the weather
Dunoon 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’s hard on glazing joints and frame seals, especially on the side facing the sea. The west of Scotland is wetter than the east, which means glazing joints and frame seals has to cope with a lot of rain.
If you live in an older home near St John’s Church (Dunoon), replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Schools such as Dunoon Primary School And Janitor's House are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. If you let a flat or house near Inverkip station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

What happens if it’s left?
Resealing cannot fix a failed unit or a cracked panel. We say so plainly and point you to a glazier or roofer. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference.

Can I do it myself?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
FAQs for Dunoon
Do you work for landlords with property near Inverkip station?
Yes, we work for landlords and letting agents. Just email us at info@mrmastic.co.uk and tell us about the property, and we will send you a clear quote.
Does living near the coast affect glazing silicone in Dunoon?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
What information do you need?
Only a few details: where it is, what you’ve noticed and how we reach it. Then drop us a line at info@mrmastic.co.uk.

The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we’ll talk you through it.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status.
Is it worth trying it myself?

Will you leave a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
