About our remedial sealant in Canonmills
Remedial work is what we do when sealant has failed or been done badly. Silicone laid over silicone, smears across tiles, the wrong product in a moving joint or mould trapped underneath all need stripping out before the joint can be done properly. We work on botched or over-sealed joints, failed movement joints and mouldy bath & shower sealant, and the jobs we see most are worktop sealant that has shrunk and split and a second bead peeling off the first.
In Scotland’s cities, including the area around Canonmills, many older flats had their bathrooms added into small rooms later on. Space is tight and ventilation can be poor, and steam with nowhere to go is what turns sealant black and grout grey.
All our work comes with a one-year guarantee, wherever you are in Edinburgh.

Signs you need remedial sealant in Canonmills
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.
Common reasons people contact us are:
- Over-sealed joints coming away
- Worktop sealant that has shrunk and split
- Floor or wall movement joints that have failed
- A shower that leaks however often it’s resealed
Letting a property close to Edinburgh Waverley station? Then botched sealant from a previous quick fix is easier to strip out between tenants.

Your questions about remedial sealant in Canonmills
Do you take on hotel work around Canonmills?
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.
Could a leaking bath seal in my Canonmills flat reach the neighbours below?
Yes, and the first sign is often a mark on the ceiling below. Cutting out the old sealant and laying a fresh bead puts a stop to it.
How long will it take to strip and reseal the joint?
That depends on how many layers there are and how many joints. You will have a timescale before any work begins.
What do you need from me for a quote?
Let us know what needs doing and where, plus photos if you have them. We will ask anything else we need to know.
Can you do several jobs on one visit?
Yes, we can. More than one area can be quoted together.
What sealant do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will tell you what we’re using.
Will it make a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status.
Bathrooms and kitchens in Canonmills
Canonmills is within about 1 mile of the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, which wears sealant and grout out faster than in a quiet home. In Scotland, private landlords have to meet the Repairing Standard, which covers keeping fixtures and fittings in a reasonable state of repair. Failed sealant around a bath or shower is worth sorting between tenancies.
For site and facilities teams at buildings such as Drummond Community High School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

How the visit works
When we arrive, we look over the joints with you first. Surfaces next to the work are protected before any work begins. The work generally takes a few hours, depending on how many layers have to come out. For a tenement in Canonmills, work inside your flat is between us and you, while shared parts may need the factor or neighbours to agree. It helps to know which it is when you get in touch.
- 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.
- The joint is tooled and you are told about anything else we found.
How to prepare
- On commercial sites, let us know about site rules
- Let us know about earlier repairs to the joints
- For indoor joints, keep the area dry beforehand if you can

Landlords, agents and businesses in Canonmills
We work for landlords and agents as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order.
Failed sealant is one of the commonest items on a check-out report. Several properties can be quoted together.
What happens if it’s left?
Adding more sealant is the usual quick fix, and it rarely works. It does not grip the old layer, so the leak carries on and there’s now more to remove. Private landlords in Canonmills must meet the Repairing Standard, and damp or leaks can fall short of it, so it’s worth fixing failed sealant before a tenant reports it.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please email us at info@mrmastic.co.uk.

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Act on a lifting corner right away
- Keep movement joints clear of mortar and paint
- Always have old sealant cut out, not covered
- Look for stains below bathrooms now and then
If the joint ever needs renewing, have it cut out, not sealed over. New silicone doesn’t bond to old, so the old bead should always come out first.
A failing joint rarely gets better on its own. Every shower or downpour sends more water through, into floors, walls or ceilings. Sorting it early limits the damage.
When something else is needed
It helps to know what we cannot do too:
- A cracked shower tray or bath (that needs repair or replacing)
- A tray or worktop that needs refixing first
- A leaking trap, valve or supply pipe
If you are not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer before you book.
What we seal
- Botched or over-sealed joints
- Mouldy bath & shower sealant
- Leaking tray & enclosure joints
- Shrunken worktop sealant
- Failed movement joints
- Expansion joints
Different surfaces, different methods
Movement & expansion joints
A movement joint must be able to stretch. Failed sealant is cut out, backing rod or tape is fitted and the joint resealed with a low-modulus product.
Mouldy bath & shower sealant
Where mould keeps coming back, ventilation is generally part of the cause. We will reseal and tell you if extraction looks to be the issue.
