Cuidhir Remedial Sealant
Our applicators work in Cuidhir on removing failed, mouldy or leaking sealant and putting it right. Old sealant removed completely, joints prepared properly.
- Wide, uneven beads that look worse than the old ones
- Torn expansion joints
- Caulk or the wrong sealant used in a wet area
How we handle remedial sealant in Cuidhir
Decorators’ caulk in a shower, bathroom silicone on a window, a rigid filler in a movement joint will not last, however tidy it looks. We take it out and use a sealant made for that joint. Typical jobs include smears and lumps from a botched reseal and beads that never stuck properly, on mouldy bath & shower sealant, failed movement joints and leaking tray & enclosure joints.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses. Older buildings can move a little, and that shows first in cracked grout and split sealant.
We stand behind the work with a one-year guarantee, so you’re covered after we’ve gone.

Quotes for remedial sealant in Cuidhir
For a quick quote, just ask. What matters most is:
- How many areas need sealing
- Which sealant suits the joint
- Mould in or behind the old joints
- The size of the job
Rather than a set price list, 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.
Asking for a quote
When you contact us, these details help:
- Access, such as stairs, a lift or height
- The problem you’ve noticed
- If someone has resealed it before
- Whether it’s a home or a business
To get a quote, send an email to info@mrmastic.co.uk and tell us where the job is and what the problem looks like. You will have a clear quote before work begins.
What happens if it’s left?
Mould under a bead cannot be reached by cleaning. The layers have to come out, so the joint can be treated and resealed. In an older home around Cuidhir, damp from a failed joint can get into timber and plaster.
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.
Why choose Mr Mastic in Cuidhir
- A sealant colour to suit the surroundings
- Over 20 years’ experience
- We leave the area clean and tidy
- Anti-fungal silicone where joints get wet

What remedial sealant looks like in Cuidhir
Cuidhir is close to 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. Island jobs need planning around ferries and the weather, so the more notice, the better.
In the older streets around Cuier Parish Church and Churchyard, walls and floors in older homes can move, and sealant and grout show it first.

How the visit works
Every visit runs the same way: we check the joints, protect the area around them, carry out the job and clear up. It normally takes a few hours, depending on how many layers have to come out. For a place like Cuidhir, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Each layer is cut out and the residue cleaned off.
- Mould is treated and the joint dried.
- We reseal with a product suited to the joint, backed where needed.
- We finish neatly and point out anything that needs another trade.
Getting ready for the visit
- Mention if the joints have been sealed before
- Tell us about any water getting in
- Try not to wet indoor joints just before the visit

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
How the job changes by surface
Mouldy bath & shower sealant
Repeat mould usually points to a damp, poorly aired room. We will reseal and tell you if extraction looks to be the issue.
Windows & doors
Wrong-coloured or messy mastic can be replaced for appearance too, matched to the frame colour.
Cuidhir questions
What guarantee comes with remedial sealant in Cuidhir?
Every job comes with our 12-month guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Will you come out to Cuidhir?
Yes, Cuidhir is covered. We work across all of Scotland, islands included, from towns to the smallest places. Longer journeys are simply planned in advance.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Can you take off two layers of silicone?
Yes. Both layers come out; over-sealing fails because silicone will not bond to silicone.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
How much does remedial sealant cost in Cuidhir?
Every job is different, so each one gets its own quote. For a quick quote, send an email to info@mrmastic.co.uk with a short description of the job.
What information do you need?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply drop us a line at info@mrmastic.co.uk.
Can old silicone be taken off without scratching the tiles?
Yes. We cut and lift the old sealant with tools suited to the surface, then clean off the residue. We point out any damage that’s already there.
What we cannot put right
It helps to know what we cannot do too:
- A bath, tray or worktop that moves until it’s properly fixed
- A tray or bath that’s cracked
- Failed tanking or loose tiles behind the sealant
Not sure which it is? You can email us at info@mrmastic.co.uk and we will tell you honestly.
Joints and surfaces we work on
- Leaking tray & enclosure joints
- Failed movement joints
- Botched or over-sealed joints
- Expansion joints
- Mouldy bath & shower sealant
- Shrunken worktop sealant
When to call us in Cuidhir
Sealant needs a clean, dry surface with no grease on it. Soap film, dust, damp or old residue stop it gripping, so it starts lifting sooner than it should.
Keep an eye out for these signs:
- Dark patches showing through the sealant
- Torn expansion joints
- Kitchen joints letting water behind the worktop
- Caulk or the wrong sealant used in a wet area
Around Cuidhir, as everywhere, remedial sealant is only as good as the preparation behind it.
Questions to ask before booking
- Whether they’re fully insured
- How the joint is cleaned and prepared
