Remedial sealant in St Fergus
If a joint fails again and again, something is causing it. A tray that moves, a worktop that isn’t fixed, the wrong sealant or water getting in elsewhere will defeat even a perfect bead. We look for the cause before we reseal. We’re often asked to deal with mould trapped under a layer of silicone and sealant applied over old sealant that has lifted, on leaking tray & enclosure joints, expansion joints and botched or over-sealed 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 guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Different surfaces, different methods
Leaking trays & enclosures
Where the joints are the problem, every bead is stripped and resealed with anti-fungal sanitary silicone, tray edges and screen profiles included.
Mouldy bath & shower sealant
Black mould inside the bead won’t scrub out. All of it comes out, and the joint is treated and dried before anti-fungal sanitary silicone goes in.

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
The difference is mostly in the preparation and the 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.
What affects the cost of remedial sealant
Jobs vary more than people expect. The main factors:
- Whether old sealant or filler has to be cut out
- Whether the work is at height
- Whether there’s mould to deal with
- Which sealant suits the joint
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Asking for a quote
What to tell us when you ask for a quote:
- Where the property is
- A few photos by email, if you can
- How we’d reach the joints
- If it’s domestic, commercial or a hotel
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.
Honest limits
A few problems are outside what sealant work can do:
- Cracks in the fitting rather than the joint
- A bath, tray or worktop that moves until it’s properly fixed
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think.
Surfaces we seal

St Fergus: your questions answered
Is there a guarantee on remedial sealant in St Fergus?
All our work, in St Fergus and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Will you come out to St Fergus?
Yes. St Fergus is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Can you remove sealant that’s been put over old sealant?
Yes. Stripping layered sealant takes longer than a normal reseal, but it’s what makes the new bead last.
Do you have insurance?
Yes. We are fully insured, and we can confirm the details when we quote.
Are you an approved applicator?
Yes. We’re an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Do you work for landlords and businesses?
Yes. We work in homes, commercial premises and hotels.
Where do you work from?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
When to call us in St Fergus
Joint depth matters. Sealant packed too deep, or stuck to the back of the joint as well as the sides, can’t stretch, and tears at the first real movement. Backing rod or bond-breaker tape prevents it.
Common reasons people contact us are:
- Products that weren’t meant for the joint
- Black mould underneath the bead
- Beads that never stuck properly
- A second bead peeling off the first
In and around St Fergus, as anywhere, good remedial sealant starts with a clean, dry, properly prepared joint.
Questions to ask before you book
- What product goes in the joint
- What happens if the job turns out different
- Are they insured?
- How the surfaces are prepared before sealing
The process
We work through the job in order: protect, prepare, seal, tidy. For most jobs that 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 generally less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Old beads and residue are removed down to clean surfaces.
- We treat any mould and dry the joint thoroughly.
- The right product goes in, with backing where the joint moves.
- We finish neatly and point out anything that needs another trade.
Before we arrive
- Tell us about any water getting in
- Plan for the work area to be out of bounds to pets and children
- Try not to wet indoor joints just before the visit

Advice
Why it’s worth doing now in St Fergus
Stripping out botched sealant adds time to a reseal, but rarely a lot: it takes a few hours, depending on how many layers have to come out. It’s far less disruption than resealing the same joint again and again. Around St Fergus, water from a failed joint in an older stone home can soak into timber and plaster.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.
What you get with us
- Neat joints and a tidy finish
- We agree the colour with you first
- Colour picked to suit the job
- We never seal over old sealant

Bathrooms and kitchens in St Fergus
St Fergus 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.
In the older streets around St Fergus Parish Church and Churchyard, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.
