Cliasmol Remedial Sealant
Removing failed, mouldy or leaking sealant and putting it right for householders, landlords and businesses in Cliasmol. Fully insured, ARBOMaster approved and guaranteed for a year.
- Smears and lumps from a botched reseal
- Sealant applied over old sealant that has lifted
- Black mould underneath the bead
How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Never seal over old silicone
- Keep the room well ventilated
- Keep bleach and abrasives off the bead
- Keep movement joints clear of mortar and paint
Keep the room ventilated: run the fan during and after showers, or open a window.
Leaks through failed sealant grow over time. Each use pushes more water behind the bead, into whatever is behind or below. Sorting it early limits the damage.
Remedial sealant in Cliasmol, done properly
A joint that keeps failing normally has a reason. Movement, the wrong product or a leak from somewhere else will defeat even a perfect bead. Finding that cause comes before any new sealant. We’re often asked to deal with products that weren’t meant for the joint and kitchen joints letting water behind the worktop, on expansion joints, botched or over-sealed joints and leaking tray & enclosure joints.
In and around a place like Cliasmol, homes range from older stone-built properties to newer houses. Where a building moves, cracked grout and split sealant are normally the first signs.
You are covered for a year from the day we finish. If there’s a problem with it, please send an email to info@mrmastic.co.uk.

DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What happens on the day
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours for most joints, depending on how much old sealant has to come out and we leave things clean and tidy. In smaller Scottish places, parking is usually less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We protect the surfaces around the joint.
- The botched or failed sealant is cut away completely.
- The joint is degreased and checked for movement and leaks.
- 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
- Let us know about parking restrictions
- Let us know about earlier repairs to the joints
- Where the joints are inside, avoid wetting them before we arrive

Advice
FAQs for Cliasmol
Is Cliasmol in your area for remedial sealant?
Yes. We work across all of Scotland, and Cliasmol is part of that. Just email us at info@mrmastic.co.uk with a few details of the job.
Do you cover smaller places like Cliasmol?
Yes. Cliasmol is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland, including the islands, where work is planned around ferry crossings. Just mention lanes, gates or anything else about the route when you book.
Can you remove old sealant without damaging the bath?
Yes. Residue is removed with a product suited to the surface rather than scraped hard, so the new sealant bonds cleanly.
Can tenants book the work?
Of course. Ask your landlord first, and we can send them the quote if that helps.
Can you do several jobs on one visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
My shower still leaks after a reseal. Can you sort it?
Yes. We will take all the sealant out, look for why it failed and reseal it properly.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
Does someone need to be in?
We need access to the joints, so we will agree that with you when we book. Indoors, that normally means someone at home.
Do you need remedial sealant in Cliasmol?
Using the wrong product is a common cause: acrylic caulk in a wet area, a general-purpose sealant on a moving joint, or an acetoxy silicone on natural stone or some metals. None of them last.
Keep an eye out for any of the following:
- Decorators’ caulk around a bath or shower
- Wide, uneven beads that look worse than the old ones
- Over-sealed joints coming away
- Mould trapped under a layer of silicone
Around Cliasmol, as everywhere, remedial sealant is only as good as the preparation behind it.
Before booking anyone
- How the surfaces are prepared before sealing
- Whether all the old sealant comes out first
- What guarantee comes with the work
- Whether VAT is included
Leave it or put it right?
Adding more sealant is the usual quick fix, and it rarely works. It can’t bond to what’s underneath, so the leak carries on and there’s now more to remove. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
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.

Remedial sealant around Cliasmol
Cliasmol is close to the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, which wears sealant and grout out faster than in a quiet home. Scotland’s water is generally soft, so sealant and grout see less limescale than in much of England. Mould is another matter: a bathroom that stays damp still turns sealant and grout black.
For jobs in and around Cliasmol, choosing the right material for each joint is as important as a tidy finish.
