How the job changes by surface
Glass-to-frame joints
Old sealant is removed carefully from the glass before new glazing silicone goes in.
Conservatory frames
The joints where the conservatory meets the house take a lot of movement. We reseal them with a sealant suited to the frame.
Glazing silicone in Bishopton, done properly
We don’t replace glass and a misted double-glazed unit needs a glazier. Our work is the sealant joints, which is where many leaks start. We work on glass-to-glass joints, shower screens and glass balustrade bases, and people most often call us about leaking glazing joints on a rooflight and silicone pulling away from the glass.
Mastic can only go onto a dry joint, so outside work in Bishopton depends on the weather. Let us know about access to every frame, including any upstairs.
You get a one-year guarantee, the same in Bishopton as everywhere else we work.

After that, the work takes a few hours, depending on how many joints need doing.

Glazing silicone in Bishopton: local notes
Bishopton 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 glazing joints and frame seals, especially on the side facing the sea. Bishopton is in the west of Scotland, which is wetter than the east, which means glazing joints and frame seals has to cope with a lot of rain.
Letting a property close to Bishopton station? Then glazing joints are worth checking at the end of a tenancy, before a small leak grows. Homes close to Church Centre include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you look after a building such as Park Mains High School, larger buildings have plenty of frames, and the mastic around each one ages.

Why it’s worth doing now in Bishopton
You do not need new glazing because the sealant has gone. Sound glass and frames usually just need resealing, and we’ll tell you if that’s not the case. In an older home around Bishopton, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, email us at info@mrmastic.co.uk for an honest opinion and a quote.

Common questions in Bishopton
Does the coastal weather in Bishopton affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Is Bishopton within the area you cover?
Yes. Bishopton 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.
Can you do several jobs on one visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
Do you take out the old sealant first?
Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
What does glazing silicone cost?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You will get a clear quote before work begins.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used before we leave.
Which silicone is used for glass joints?
A glazing silicone chosen for the joint. Neutral-cure silicone is the usual choice.
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Use a gentle glass cleaner and a soft cloth
- Avoid scraping close to the bead
- Avoid strong solvents on or near the sealant
- Open vents or windows to let moisture out
Look over the glazing joints every year or so. Catching a split early keeps the repair small, before water gets in.
Shower screen leaks can go unnoticed. It can damage the floor or the ceiling below before you spot it.
