Silverknowes questions
Do you work for landlords with property near South Gyle station?
Yes, rental work is part of what we do. You can send an email to info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before work begins.
I’m in a tenement in Silverknowes. Could worn sealant affect the flat downstairs?
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.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
What does remedial sealant cost?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before we start.
Can you remove old sealant without damaging the bath?
Yes. We cut and lift the old sealant with tools suited to the surface, and the residue is cleaned away. We point out any damage that is already there.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done and you’ll get one quote.
How long will it take to strip and reseal the joint?
That depends on how many layers there are and how many joints. We will tell you before work begins.
About our remedial sealant in Silverknowes
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. If you are dealing with wide, uneven beads that look worse than the old ones and over-sealed joints coming away, we can put it right.
Stone-built tenements are part of every Scottish city, alongside suburban houses and modern blocks. In a tenement, most bathrooms sit above someone else’s ceiling, so failed sealant around a bath or shower can soon become a neighbour’s problem.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
What we cannot put right
We will not take on work that will not last, so here’s what sealant cannot put right:
- A tray or worktop that needs refixing first
- Cracks in the fitting rather than the joint
- Water damage behind tiles that needs a tiler
If you’re not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer.

Remedial sealant in Silverknowes: local notes
Silverknowes is within about 1 mile of 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. 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.
If you live in an older home near St Columba's Parish Church, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. Letting a property close to South Gyle station? Then failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.
Silverknowes is about 3 miles north-west of Edinburgh, in Edinburgh. Homes, rented property, offices and hotels in Silverknowes is covered for remedial sealant. Every job comes with our 12-month guarantee. Silverknowes is one of 175 places in Edinburgh where we work for remedial sealant.

Why it’s worth doing now in Silverknowes
Leaks that are left keep doing damage out of sight: wet floors, stained ceilings and swollen worktops. Dealing with the joint now is a small job by comparison. Wind-driven rain gets into any failed joint on the outside of a city building, and in Silverknowes, damp can spread through stone and plaster before anyone sees it.
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and give you a clear quote before work begins.

What the job involves on each surface
Movement & expansion joints
Joints filled with mortar, grout or rigid filler cannot move. We rake that out where it can be removed and seal with a flexible product.
Worktops & kitchens
Kitchen joints often have grease and cleaning residue deep in them, so we spend extra time cleaning before resealing.
Do you need remedial sealant in Silverknowes?
Even good sealant ages. Over the years it shrinks, hardens and gets colonised by mould, faster where ventilation is poor. At that point it has to come out.
Keep an eye out for these signs:
- Torn expansion joints
- Over-sealed joints coming away
- Smears and lumps from a botched reseal
- A shower that leaks however often it’s resealed
If you look after a building such as Craigroyston Community High School, we reseal washrooms and kitchens in schools and businesses as well as homes.

The process
We bring everything the job needs with us, so there’s nothing for you to buy. Once we’ve agreed what’s being done, we protect the area and start. It normally takes a few hours for a typical bath or shower, longer where several layers have been applied. In a city area like Silverknowes, 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.
- We treat any mould and dry the joint thoroughly.
- We reseal with a product suited to the joint, backed where needed.
- We finish neatly and point out anything that needs another trade.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Mention any sign-in or site rules at work premises
- Keep pets and children clear of the area while we work
Ask for a quote
Asking for a quote is easy: let us know the job and the location. A few photos by email make the job easier to understand, and we will come back to you with a quote.

Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Never fill a movement joint with mortar or grout
- Always have old sealant cut out, not covered
- Keep an eye on the ceiling below the bathroom
- Run the fan after every shower
Keep the room ventilated: use the extractor or open a window after showering.
If a joint has failed more than once, stop resealing it. Get the cause found first, or the next bead will go the same way.
