About our remedial sealant in Carrick Knowe
Some sealant jobs aren’t a simple reseal, because someone has already had a go. Silicone laid over silicone, smears across tiles, the wrong product in a moving joint or mould trapped underneath all have to come out. We work on mouldy bath & shower sealant, expansion joints and shrunken worktop sealant, and the jobs we see most are black mould underneath the bead and sealant applied over old sealant that has lifted.
Stone-built tenements are part of every Scottish city, alongside suburban houses and modern blocks. With flats above and below, a leak from a tired seal can reach the flat underneath, and that is as true in Carrick Knowe as anywhere in the city.
A 12-month guarantee comes as standard, so you’re not left on your own once the job is done.

Windows & doors
Wrong-coloured or messy mastic can be replaced for appearance too, in a colour that suits the frame.
Over-sealed & botched joints
A botched joint can hide two or three layers of sealant, and silicone residue is cleaned off the tiles too. Only a clean joint will take a new bead.
DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
What a professional job adds is preparation and the right 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.
Leave it or put it right?
Spraying mould remover on a sealed-over joint doesn’t reach what’s underneath. The layers have to come out. Scottish rain finds any gap around a frame or wall joint, and in a tall building in Carrick Knowe, damp can travel a long way before it shows.
Combining jobs into one visit usually makes better use of the time than several visits. We will send you a clear quote for the lot.

How we quote for remedial sealant
Jobs vary more than people expect. The main factors:
- How easy the joints are to reach
- How many rooms, windows or areas are involved
- The product the joint needs
- Working hours on commercial sites
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
What to tell us for a quote
Before you ask for a quote, have a think about:
- Where the property is
- Photos by email, if that is easy
- How we’d reach the joints
- Roughly how big the job is
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and add pictures by email if you can.

Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Keep movement joints clear of mortar and paint
- Never seal over old silicone
- Ask why a joint failed before redoing it
- Deal with small splits early
Keep the room ventilated: use the extractor or open a window after showering.
Mould under a second layer of sealant keeps growing out of sight. By the time it shows through, the joint is well past saving.

Remedial sealant in Carrick Knowe: local notes
Carrick Knowe 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, where a failed seal can soon reach the flat below.
If you live in an older home near St Anne's Parish Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them. 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.

How it works
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. It usually takes a few hours for most joints, depending on how much old sealant has to come out. Inside a flat in Carrick Knowe, the job is planned with you; outside, shared parts may need the factor or other owners involved. It helps to know which it is when you get in touch.
- Surrounding tiles, trays and frames are protected first.
- 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.
Preparing for the visit
- On commercial sites, let us know about site rules
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know if you’ve seen damp or leaks

When to call us in Carrick Knowe
Silicone only bonds to surfaces that are clean and dry. Residue, moisture or dust left in the joint weaken the bond, so it starts lifting sooner than it should.
These are the problems we’re asked about most:
- Movement joints that have split or pulled away
- Products that weren’t meant for the joint
- Gaps opening along the back of the worktop
- Leaks that keep coming back after resealing
If you look after a building such as Scotus Academy, 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.
What to look for in a quote
- Is the old sealant removed completely?
- When the joint can take water or movement
- What insurance they hold
- How long the guarantee is
