Glazing silicone in Janetstown
Frameless shower screens rely on sealant to keep water in. The joint down the wall and the one along the tray are common leak points and both get fresh anti-fungal silicone. If you’re dealing with new silicone smeared over old sealant and failed joints on frameless glass, we can put it right, on shower screens, glass-to-glass joints and rooflights alike.
Mastic can only go onto a dry joint, so outside work in Janetstown depends on the weather. Let us know about access to every frame, including any upstairs.
A one-year guarantee comes with the work, just as it does everywhere we cover.

What glazing silicone looks like in Janetstown
Janetstown 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’s hard on glazing joints and frame seals, especially on the side facing the sea. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
If you let a flat or house near Thurso station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. If you look after a building such as Thurso High School, its window and door frames need their mastic kept sound, just like a home’s.
Janetstown is about 3 miles south-west of Thurso, in Highland. Across the KW14 area, we cover glazing silicone for homes and businesses. 253 places in Highland are on our list, from the larger towns to small villages.

When it is not the sealant
We’ll always be straight with you, so here’s what new sealant won’t do:

Where we work in Janetstown
- Glass-to-glass joints
- Shower screens
- Glass-to-frame joints
- Conservatory frames
- Rooflights
- Glass balustrade bases
Keeping the joints in good condition
After the cure time, these simple habits help:
- Do not leave a drip for the next storm
- Clean glass with a mild cleaner and a soft cloth
- Check the gutters above the glazing for debris
- Check the silicone on glass every year or so
Use mild cleaners on and around the silicone. Strong solvents can soften or mark it.
Act on black or lifting silicone early. Once it starts to peel, water gets behind it and the leak gets worse.
Why deal with it now?
Silicone around glazing needs the right product. A general-purpose tube may not bond well or may react with the frame, so we use neutral-cure glazing silicone. Around Janetstown, water from a failed joint in an older stone home can soak into timber and plaster.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.

Common questions in Janetstown
Is Janetstown within the area you cover?
Yes. Janetstown is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
I let a flat near Thurso station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can go on one quote. You can send an email to info@mrmastic.co.uk with the details for a clear quote.
Where is Mr Mastic based?
We’re based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
How long before the joint can be used?
Different products cure at different speeds, so please follow the time we give you when we finish.
Do you remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Can you fix a leaking conservatory?
It depends on the cause. Failed glazing and frame joints can be resealed but roof and panel problems need another trade.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Do you reseal glass shower screens?
Yes. We remove the old sealant and reseal the wall and tray joints.
