What we’re called out for in Canongate
Sealant needs a clean, dry surface with no grease on it. Soap film, dust, damp or old residue stop it gripping, so it starts lifting sooner than it should.
Any of these means the joints need attention:
- Black mould underneath the bead
- Kitchen joints letting water behind the worktop
- A second bead peeling off the first
- Wide, uneven beads that look worse than the old ones
Schools such as Old Royal High School are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
Questions to ask before you book
- Whether all the old sealant comes out first
- What guarantee comes with the work
- What happens if they find a problem under the old sealant
- What product goes in the joint
About our remedial sealant in Canongate
The wrong product in the wrong joint won’t last, however tidy it looks. We take it out and use a sealant made for that joint. We work on mouldy bath & shower sealant, failed movement joints and botched or over-sealed joints, and the jobs we see most are torn expansion joints and kitchen joints letting water behind the worktop.
Canongate is in one of Scotland’s four big cities, where many tenement bathrooms were fitted into rooms that weren’t built for them. Rooms like that are often small and slow to dry out, which is hard on sealant and grout.
A 12-month guarantee comes as standard.

Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Work for landlords, hotels and businesses
We also work for property managers and facilities teams in Canongate and across Edinburgh. Several sites can go on one quote, and we are fully insured for the work.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
Why it’s worth doing now in Canongate
It’s easy to scratch acrylic, enamel or an uPVC frame cutting out old sealant, and any film left behind stops new sealant sticking. Careful stripping is where most of our time goes. In a tenement flat in Canongate, a failed seal is rarely just your problem: a leak can come through the ceiling below, and gaps in shared walls or fire-rated joints matter to every flat.
The cost reflects the work involved, not guesswork. That is why we ask a few questions first and give you a clear price before any work starts.
What you get with us
- A 12-month guarantee on all work

Canongate: your questions answered
I’m in a tenement in Canongate. Could worn sealant affect the flat downstairs?
It can. Tenement floors are generally 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.
Do you work for hotels and guest houses in Canongate?
Yes, we work for hotels as well as homes and businesses. A room-by-room programme keeps most rooms in use while the work goes on.
What information do you need?
Only a few details: where it is, what you’ve noticed and how we reach it. Then send an email to info@mrmastic.co.uk.
Can failed expansion joints be resealed?
Yes. Backing sets the depth and stops the sealant sticking to the back, which lets it stretch.
I’m a tenant. Can you help?
Of course. Check with your landlord; we can send the quote to them too.
How do I get a quote for remedial sealant in Canongate?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done.
Do you offer different sealant colours?
Yes. Sealants come in white, clear, grey and other colours for many products, and we’ll agree it with you first.
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Do not wait for a small gap to become a leak
- Use a soft cloth, not a scourer, on silicone
- Check ceilings under showers for marks
- Always have old sealant cut out, not covered
Where we have pointed out another fault, have it put right, because the new sealant can’t hold back a problem underneath.
Mould trapped under over-sealed joints spreads unseen. By the time it shows through, the joint is well past saving.
Bathrooms and kitchens in Canongate
Canongate is close to the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, and sealant and grout that work that hard wear out sooner. 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.
In the older streets around Kirk of the Canongate, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. Rented homes near Edinburgh Waverley station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

What we do, step by step
When we arrive, we look over the joints with you first, so you know exactly what we are doing. We protect the surfaces around the joints before any work begins. The work normally takes a few hours for a typical bath or shower, longer where several layers have been applied. In a city area like Canongate, parking may be by permit or pay-and-display, so tell us what’s nearby. If you’re in a flat, let us know how we get in at the street door.
- First we work out whether the problem is the sealant, movement or a leak.
- Each layer is cut out and the residue cleaned off.
- Mould is treated and the joint dried.
- The right product goes in, with backing where the joint moves.
- The joint is tooled and you’re told about anything else we found.
Getting ready for the visit
- Clear the area around the work
- Let us know if you’ve seen damp or leaks
- For business premises, tell us about site rules or sign-in

Advice
Different surfaces, different methods
Movement & expansion joints
Bonding on three sides is a common reason movement joints tear. Backing stops that, letting the sealant flex between the two faces.
Worktops & kitchens
Old kitchen sealant pulls back from the wall over time. It’s cut out, degreased and resealed colour-matched to the worktop.
