About our remedial sealant in Perth
Not every leak is a sealant leak. A cracked tray, a failed shower valve or a leaking waste can look just the same. If that’s what we find, we’ll tell you rather than reseal something that will not fix it. We work on botched or over-sealed joints, shrunken worktop sealant and leaking tray & enclosure joints, and common reasons people get in touch are mould trapped under a layer of silicone and sealant that came away because the surface wasn’t prepared.
In a town like Perth, stone-built older streets normally sit alongside harled houses and newer estates. Bathrooms and kitchens across all of them need their sealant and grout renewing from time to time.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Looking after it afterwards
After the cure time, these simple habits help:
- Run the fan after every shower
- Don’t wait for a small gap to become a leak
- Never fill a movement joint with mortar or grout
- Ask why a joint failed before redoing it
If we’ve found a cause, such as a loose tray or a leaking waste, get it fixed, because the new sealant cannot hold back a problem underneath.
Leaks through failed sealant grow over time. Each use pushes more water behind the bead, into floors, walls or ceilings. Early action keeps it to a sealant job.
Remedial sealant in Perth: local notes
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. Private landlords in Scotland must be registered and meet the Repairing Standard, which covers keeping fixtures and fittings in a reasonable state of repair. Tired, leaking sealant is worth putting right before a new tenant moves in.
For site and facilities teams at buildings such as Perth High School, washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes.

DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, 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. Everything old must be removed first.
Honest limits
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- A tray or worktop that needs refixing first
- Failed tanking or loose tiles behind the sealant
- Plumbing leaks behind walls or under trays
If you are not sure, just send an email to info@mrmastic.co.uk and we’ll give you a straight answer.
Where we work in Perth
- Shrunken worktop sealant
- Leaking tray & enclosure joints
- Expansion joints
- Failed movement joints
- Botched or over-sealed joints
- Mouldy bath & shower sealant
The process
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours for most joints, depending on how much old sealant has to come out. For a job in Perth, tell us where the work is, how to get in and where to park. Outside work depends on the weather, as sealant needs a dry surface.
- We protect the surfaces around the joint.
- The botched or failed sealant is cut away completely.
- We clean and degrease the joint and look for signs of movement or water.
- New sealant goes in once the joint is dry, and is tooled smooth.
- You get the cure time and our view on why the joint failed.
Before we arrive
- Try not to wet indoor joints just before the visit
- Keep pets and children clear of the area while we work
- Mention if the joints have been sealed before

What else we do in Perth
Why it’s worth doing now in Perth
A failed seal rarely means a new bathroom. When the fittings are sound, stripping and resealing the joints is often enough. Where something else has failed, you’ll hear it from us. In Perth, wind and rain soon get through failed outside joints. Indoors, failed sealant lets water into floors and ceilings.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first and send you a clear quote before any work starts.

FAQs for Perth
Do you work for hotels and guest houses in Perth?
Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.
I let a flat near Perth station. Can you help?
Yes. We work for landlords and agents as well as householders. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.
My shower still leaks after a reseal. Can you sort it?
Yes. We will take all the sealant out, look for why it failed and reseal it properly.
Can you quote for more than one area?
Yes. Just list everything you need and we will quote it together.
What do you put in the joint?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
How do I get a quote for remedial sealant in Perth?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
Will there be a smell?
It depends on the product. Some smell for a while, some hardly at all.
What if resealing won’t fix my leak?
We will tell you. A cracked tray, faulty valve or leaking waste needs a different trade, so we won’t pretend it will.
Do you need remedial sealant in Perth?
Some joints fail because water is reaching them from behind. A slow leak behind the tiles soaks the joint from the back, and the sealant lifts or goes mouldy from underneath.
These are the problems we are asked about most:
- Sealant that came away because the surface wasn’t prepared
- Floor or wall movement joints that have failed
- Decorators’ caulk around a bath or shower
- A shower that leaks however often it’s resealed
If you let a flat or house near Perth station, botched sealant from a previous quick fix is easier to strip out between tenants.
