Common problems we fix in Leverburgh
Sealant needs a clean, dry surface with no grease on it. Soap film, dust, damp or old residue stop it gripping, and the joint starts to come away early.
These are the problems we’re asked about most:
- Sealant peeling off a dusty or damp surface
- Black mould underneath the bead
- Leaks that keep coming back after resealing
- Products that weren’t meant for the joint
For jobs in and around Leverburgh, choosing the right material for each joint is as important as a tidy finish.

Remedial sealant in Leverburgh, done properly
Decorators’ caulk in a shower, bathroom silicone on a window, a rigid filler in a movement joint fails however neatly it’s applied. We take it out and use a sealant made for that joint. We’re often asked to deal with worktop sealant that has shrunk and split and sealant peeling off a dusty or damp surface, on leaking tray & enclosure joints, failed movement joints and shrunken worktop sealant.
In and around a place like Leverburgh, homes range from older stone-built properties to newer houses. Where a building moves, cracked grout and split sealant are normally the first signs.
We stand behind the work with a 12-month guarantee, so you’re not left on your own once the job is done.

How we quote for remedial sealant
There’s no set price list, because no two jobs are the same. The quote depends on:
- The size of the job
- Whether there’s mould to deal with
- Whether old sealant or filler has to be cut out
- Whether the work is at height
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, drop us a line at info@mrmastic.co.uk for an honest opinion and a quote.
What we need to know
What to tell us when you ask for a quote:
- The rough size of the job
- The address or postcode of the job
- What the problem is, such as mould, gaps, leaks or cracking
- Access, such as stairs, a lift or height
To get a quote, drop us a line at info@mrmastic.co.uk and tell us where the job is and what the problem looks like. We’ll send you a clear quote before any work starts.
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Leverburgh: your questions answered
Do you cover smaller places like Leverburgh?
Yes. Leverburgh is within the area we cover, which takes in towns, villages and rural addresses. We work across all 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.
Is remedial sealant in Leverburgh guaranteed?
All our work, in Leverburgh and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Someone sealed over the old bead. Can you fix it?
Yes. We cut out all the layers and clean off the film, before resealing with a single bead.
Can you reseal a split movement joint?
Yes. Where mortar or filler has been used instead of sealant, it’s removed where it can be, then the joint is sealed properly.
Can I choose the sealant colour?
We help you choose a colour that suits, from white and clear to greys and other shades. The choice depends on the product the joint needs.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator.
What does remedial sealant cost?
It depends on the job, so we quote each one individually. To get one, email us at info@mrmastic.co.uk and tell us what needs doing and where.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
What we can’t put right
It helps to know what we can’t do too:
- Movement from fittings that are not supported
- A cracked shower tray or bath (that needs repair or replacing)
- Sealant in an older building that needs testing for asbestos first
If you are not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer.

Remedial sealant around Leverburgh
Leverburgh is close to 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. Scotland’s water is generally soft, so sealant and grout see less limescale than in much of England. But mould still grows into sealant and grout in a room that does not dry out.
Around Leverburgh, as everywhere, remedial sealant is only as good as the preparation behind it.
