How it works
Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours, depending on how many layers have to come out. Parking in city streets around Shieldhall can be tight or controlled, so it helps to know about permits or nearby bays. If you’re in a flat, let us know how we get in at the street door.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Old beads and residue are removed down to clean surfaces.
- Mould is treated and the joint dried.
- The right product goes in, with backing where the joint moves.
- We finish neatly and point out anything that needs another trade.
Getting ready for the visit

About our remedial sealant in Shieldhall
A joint that keeps letting you down needs more than another bead. It helps to have photos when you email us at info@mrmastic.co.uk, along with when it was last resealed. If you have a shower that leaks however often it’s resealed and decorators’ caulk around a bath or shower, we can put it right, whatever the surface.
Shieldhall is in one of Scotland’s four big cities, where many tenement bathrooms were fitted into rooms that weren’t built for them. Space is tight and ventilation can be poor, which is hard on sealant and grout.
Whatever the size of the job, you get the same 12-month guarantee.

When it is not the sealant
It helps to know what we cannot do too:
- Tiles that have come away from the wall
- A leaking trap, valve or supply pipe
- Movement from fittings that are not supported
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think before you book.
Where we work in Shieldhall
- Expansion joints
- Leaking tray & enclosure joints
- Botched or over-sealed joints
- Mouldy bath & shower sealant
- Failed movement joints
- Shrunken worktop sealant
What happens if it’s left?
Stripping out botched sealant adds time to a reseal, but rarely a lot: it takes a few hours for a typical bath or shower, longer where several layers have been applied. It’s far less disruption than resealing the same joint again and again. For landlords in Shieldhall, damp and leaks can be a Repairing Standard issue, so failed sealant is best replaced before it becomes a complaint.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs. Call for a quick quote and we will go through it with you.

Shieldhall questions
Can a failed shower seal in a tenement flat in Shieldhall leak into the flat below?
Yes, and the first sign is often a mark on the ceiling below. A proper reseal, with all the old sealant cut out, stops it at the source.
Can you help a landlord with a rental near Hillington West station?
Yes. We work for landlords and agents as well as homeowners. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear quote.
How long should I leave it?
Different products cure at different speeds, so follow the cure time we give you.
My shower still leaks after a reseal. Can you sort it?
Yes. Repeat leaks normally come from over-sealing, movement or water getting in elsewhere, and we deal with the cause first.
Do you work in Shieldhall?
We do. Our applicators work in Shieldhall, and the service is the same as everywhere else.
How long does remedial resealing take?
Allow a few hours for a typical bath or shower, longer where several layers have been applied. We will give you a timescale when we quote.
Are you insured?
Yes. We’re fully insured.
What does remedial sealant cost?
Size, access and the old material all affect the cost. Ask us for a quote and we will talk you through it.

How we quote for remedial sealant
Jobs vary more than people expect. What affects the quote:
- How many rooms, windows or areas are involved
- Any mould that needs treating
- The old material and how stubborn it is
- Which sealant suits the joint
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, email us at info@mrmastic.co.uk and we’ll give you an honest view and a quote.

To help us quote quickly, please include:

- The rough size of the job
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add pictures by email if you can.
DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Never fill a movement joint with mortar or grout
- Run the fan after every shower
- Don’t add new sealant on top of old
- Keep bleach and abrasives off the bead
Where we’ve pointed out another fault, have it put right, or the new joint may fail again.
Leaks through failed sealant grow over time. Every shower or downpour sends more water through, into whatever is behind or below. Sorting it early limits the damage.
Remedial sealant around Shieldhall
Private landlords in Scotland must be registered and meet the Repairing Standard, which includes keeping fixtures and fittings in reasonable repair. Tired, leaking sealant is worth putting right before a new tenant moves in. Scottish Water supplies are generally soft, so limescale is less of a problem than in hard-water areas. Mould is another matter: a bathroom that stays damp still turns sealant and grout black.
For site and facilities teams at buildings such as Renfrew High School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. Rented homes near Hillington West station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.
