Why deal with it now?
Dealing with a leaking shower screen early protects the floor and ceiling. Water from a failed joint can soak into the floor before you notice. In a place like Dunbar, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.

Glazing silicone in Dunbar
Not every silicone suits glass. Our applicators use neutral-cure glazing silicone that is suited to glass and the frame, and we tool it to a neat, even finish. We work on glass-to-glass joints, shower screens and glass balustrade bases, and common reasons people get in touch are leaks where conservatory glass meets the frame and shower screens leaking along the wall or tray.
Outdoor sealant needs a dry surface, so window work around Dunbar 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.

How the job changes by surface
Shower screens
Most shower screen leaks come from the wall or tray joint. Both are resealed with anti-fungal silicone.
Glass-to-glass joints
Glass-to-glass joints depend entirely on the sealant. It must be clean, neat and well bonded.
FAQs for Dunbar
Does living near the coast affect glazing silicone in Dunbar?
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.
Can you help a landlord with a rental near Dunbar station?
Yes, rental work is part of what we do. You can send an email to info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before we start.
Is it enough to run a bead over the old sealant?
A top-up rarely holds. Fresh silicone will not bond to cured silicone so we take it all out and start clean.
Can you reseal the base of a glass balustrade?
Yes, we reseal the joint at the base channel. We do not install or replace the glass.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Do you have insurance?
Yes, we are fully insured for every job we do.
What do you need from me for a quote?

Glazing silicone in Dunbar: local notes
Dunbar 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. Both are hard on glazing joints and frame seals, which can dry out and crack sooner where a building faces the weather. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
Rented homes near Dunbar station change hands often, and leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.

How we quote for glazing silicone
Call for a quick quote. The main things that affect it are:
- Whether old sealant or filler has to be cut out
- Whether there’s mould to deal with
- The amount of work
- Working hours on commercial sites
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
What we need to know
When you contact us, these details help:
- How we’d reach the joints
- The problem you’ve noticed
- Roughly how big the job is
- The type of property
We quote each job on its own. Just send an email to info@mrmastic.co.uk with the details, and photos are welcome.
Looking after it afterwards
After the cure time, these simple habits help:
- Act on drips or damp patches early
- Wipe the screen down after showering
- Open vents or windows to let moisture out
- Avoid strong solvents on or near the sealant
Gentle products are best near the sealant. Strong solvents can soften or mark it.
A leaking shower screen may not show at first. Water can soak into the floor or reach the room below before you spot it.
Common problems we fix in Dunbar
Using a sealant not made for glass causes many failures. Some products do not bond well to glass and vinegar-smelling acetoxy silicone can attack some metals.
Keep an eye out for any of the following:
- Failed sealant around rooflight glass
- Drips on the inside of a conservatory window
- Stained, discoloured glazing silicone
- Water getting into a conservatory at the joints
In the older streets around Abbey Church of Scotland, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
