About our remedial sealant in Blackhall
A joint that keeps failing normally has a reason. Movement, the wrong product or a leak from somewhere else will beat any new bead. We look for the cause before we reseal. We’re often asked to deal with caulk or the wrong sealant used in a wet area and a second bead peeling off the first, on mouldy bath & shower sealant, shrunken worktop sealant and leaking tray & enclosure joints.
Blackhall 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.
All our work comes with a one-year guarantee, wherever you are in Edinburgh.

Why it’s worth doing now in Blackhall
A failed seal rarely means a new bathroom. If the bath, tray and tiles are sound, remedial resealing generally puts it right. If they’re not, we’ll tell you. For landlords in Blackhall, damp and leaks can be a Repairing Standard issue, so it’s worth fixing failed sealant before a tenant reports it.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
What you get with us
- Anti-fungal silicone where joints get wet

FAQs for Blackhall
Can you help a landlord with a rental near Haymarket station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.
Do you take on hotel work around Blackhall?
Yes. Hotel and guest-house work is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
My shower still leaks after a reseal. Can you sort it?
Yes. All the sealant comes out, we find out why it failed, and the joint is resealed properly.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Will the old sealant be removed?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.
Do you fix expansion and movement joints?
Yes. We cut out the failed sealant, fit backing and reseal with a flexible product.
Can you strip sealant from an acrylic tray safely?
Yes. We take our time over removal, particularly on softer surfaces like acrylic.
Can I add another job to the visit?
Yes, we can. More than one area can go on one quote.
What we cannot put right
We’ll always be straight with you, so here’s what sealant cannot fix:
- Older mastics that may need an asbestos check before removal
- Plumbing leaks behind walls or under trays
- A bath, tray or worktop that moves until it’s properly fixed
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly.
What we seal
- Expansion joints
- Shrunken worktop sealant
- Failed movement joints
- Mouldy bath & shower sealant

For landlords and businesses
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can be quoted together.

- 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.
Preparing for the visit

Common problems we fix in Blackhall
Silicone only bonds to surfaces that are clean and dry. Soap film, dust, damp or old residue stop it gripping, so it starts lifting sooner than it should.
These are the problems we’re asked about most:
- Black mould underneath the bead
- Movement joints that have split or pulled away
- Thick, messy sealant smeared over tiles
- Sealant applied over old sealant that has lifted
If you look after a building such as The Mary Erskine 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.
Questions to ask before you book
- How long the guarantee is
- What happens if they find a problem under the old sealant
- What the cure time is
- How the surfaces are prepared before sealing
Remedial sealant around Blackhall
Blackhall is close to the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, and sealant and grout that work that hard wear out sooner. Edinburgh has a lot of tenement flats, in the Old and New Towns and well beyond, and in a tenement, a leaking seal can reach the neighbours below.
For an older house near a landmark such as St Columba's Parish Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them. Letting a property close to Haymarket station? Then a joint that keeps failing is best fixed properly while the property is empty.

Different surfaces, different methods
Mouldy bath & shower sealant
Black mould inside the bead will not scrub out. The sealant is cut out completely, the joint treated with a mould remover and dried ahead of a new anti-fungal bead.
Worktops & kitchens
Kitchen joints hold grease and residue, so cleaning takes longer than in a bathroom before resealing.
What affects the cost of remedial sealant
Jobs vary more than people expect. The main factors:
- Working hours on commercial sites
- Whether there’s mould to deal with
- The amount of work
- Whether the work is at height
A failed joint rarely gets cheaper to fix by waiting. If you’re unsure, drop us a line at info@mrmastic.co.uk for an honest opinion and a quote.
