- Gaps opening along the back of the worktop
Aftercare tips
Aftercare is simple, and it makes a real difference:
- Find out why the sealant failed first
- Air the bathroom so the sealant can dry
- Check ceilings under showers for marks
- Use a soft cloth, not a scourer, on silicone
If we’ve found a cause, such as a loose tray or a leaking waste, get it fixed, because the new sealant can’t hold back a problem underneath.
Movement joints that have split let water into the structure, and the longer it’s left, the more the joint edges break down. A joint with sound edges is far easier to reseal.
How we handle remedial sealant in Port Dundas
In Port Dundas, as anywhere, remedial jobs tend to look alike: over-sealed joints, hidden mould, repeat leaks and split movement joints. Each is stripped back and done again properly. We work on expansion joints, failed movement joints and shrunken worktop sealant, and people most often call us about products that weren’t meant for the joint and torn expansion joints.
Scotland’s cities have a lot of flats, from sandstone or granite tenements to modern blocks, as well as houses in the suburbs. Generally soft Scottish water means less limescale, but steam and poor ventilation still let mould into the sealant and grout.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Leave it or put it right?
Repeat failures have a cause. Finding it, whether movement, water from elsewhere or an unsuitable product, ends the cycle. Wind-driven rain gets into any failed joint on the outside of a city building, and in Port Dundas, damp can spread through stone and plaster before anyone sees it.
Combining jobs into one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

Surface by surface
Leaking trays & enclosures
A shower that leaks after resealing often has a tray that moves or an enclosure sealed on the wrong side. Both are checked before any new sealant goes on.
Mouldy bath & shower sealant
Black mould inside the bead won’t scrub out. All of it comes out, and the joint is treated and dried ahead of a new anti-fungal bead.

What remedial sealant looks like in Port Dundas
Scotland’s water is generally soft, so sealant and grout see less limescale than in much of England. Mould is another matter: a bathroom that stays damp still turns sealant and grout black. Glasgow has a lot of sandstone tenements, so many bathrooms sit right above a neighbour’s ceiling.
If you let a flat or house near Glasgow Queen Street station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

Do you need remedial sealant in Port Dundas?
All sealant wears out eventually. Mould grows into the silicone, the surface hardens and the bead shrinks, especially in damp, poorly aired rooms. At that point it has to come out.
Any of these means the joints need attention:
- Decorators’ caulk around a bath or shower
- Beads that never stuck properly
- A second bead peeling off the first
- Thick, messy sealant smeared over tiles
For site and facilities teams at buildings such as St Aloysius' College, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

How the visit works
When we arrive, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before any work begins. Most jobs take a few hours for a typical bath or shower, longer where several layers have been applied. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. For a job in Port Dundas, tell us the floor, how the door entry system works and where we can park nearby.
- First we find out how and where the joint has failed.
- We strip the joint completely, removing any layers below.
- We clean the joint, treat any mould and let it dry.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- Finally we finish the joint and talk you through what we found.
Getting ready for the visit
- Plan for the work area to be out of bounds to pets and children
- Mention any leaks or damp you’ve noticed
- Move anything stored near the joints
Getting a quote
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.
Advice
Common questions in Port Dundas
I let a flat near Glasgow Queen Street station. Can you help?
Yes, rental work is part of what we do. You can email us at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before any work starts.
I’m in a tenement in Port Dundas. Could worn sealant affect the flat downstairs?
It can. Tenement floors are normally timber, and water from a failed seal can find its way down to the flat below, and then the repair involves your neighbours too. It’s worth sorting sealant and grout before it gets that far.
Does remedial work come with a guarantee?
Yes. You get our 12-month guarantee, and we are ARBOMaster approved.
What does remedial sealant cost?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Do you work in Port Dundas?
Yes. We cover Port Dundas and the rest of Glasgow, as part of our work across South East England, London and Scotland. To book, email us at info@mrmastic.co.uk.
Can old silicone be taken off without scratching the tiles?
Yes. We cut and lift the old sealant with tools suited to the surface, and the residue is cleaned away. We point out any damage that is already there.
Someone resealed my shower and it’s leaking again. Can you help?
Yes, usually. We check it’s the sealant and not the tray, valve or waste, then strip and reseal the joints.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
