Surface by surface
Mouldy bath & shower sealant
Mould often spreads under the bead as well as through it. Once it’s all removed, the joint is treated so the new sealant starts clean.
Movement & expansion joints
Joints filled with mortar, grout or rigid filler can’t move. We rake that out where it can be removed and seal with a flexible product.
About our remedial sealant in Cove
Remedial jobs in Cove generally fall into a few patterns: sealant over sealant, mould under the bead, leaks that come back and movement joints that have split. We strip each one back and start from scratch. We are often asked to deal with sealant that came away because the surface wasn’t prepared and kitchen joints letting water behind the worktop, on expansion joints, botched or over-sealed joints and leaking tray & enclosure joints.
Bathrooms in smaller places like Cove work just as hard as those in the cities. Generally soft Scottish water means less limescale, but steam still lets mould into sealant and grout.
Whatever the size of the job, it’s backed by our one-year guarantee.

Remedial sealant in Cove: local notes
Cove 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. Private landlords in Scotland must be registered and meet the Repairing Standard, which includes keeping fixtures and fittings in reasonable repair. Tired, leaking sealant is worth putting right before a new tenant moves in.
For an older house near a landmark such as Craigrownie Church, walls and floors in older homes can move, and sealant and grout show it first. For landlords with property near Gourock station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

What else we do in Cove
How it works
We bring everything the job needs with us, so there’s nothing for you to buy. Once we’ve agreed what’s being done, the area is protected and the work begins. It normally takes a few hours for most joints, depending on how much old sealant has to come out. In smaller Scottish places, parking is usually less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- 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.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Clear items away from the joints we are working on
- Mention any tricky access

Advice
How we quote for remedial sealant
Jobs vary more than people expect. What affects the quote:
- Whether the work is at height
- How many areas need sealing
- Mould in or behind the old joints
- Working hours on commercial sites
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
What we need to know
There’s no need for technical detail. It helps if you can tell us:
- Roughly how big the job is
- Whether it has been sealed before
- The problem you’ve noticed
- Any access issues, like height or stairs
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. When it suits you, send an email to info@mrmastic.co.uk.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Look for stains below bathrooms now and then
- Always have old sealant cut out, not covered
- Keep bleach and abrasives off the bead
- Air the bathroom so the sealant can dry
Give the new sealant its full cure time: normally around 24 hours, or as long as we advise.
Movement joints that have split let water into the structure, and left long enough, the edges of the joint can crumble. Resealing while the edges are sound is simpler.
