About our remedial sealant in Gargunnock
The wrong product in the wrong joint fails however neatly it’s applied. Out it comes, and in goes a sealant suited to the job. Common call-outs are for beads that never stuck properly and worktop sealant that has shrunk and split, across leaking tray & enclosure joints, botched or over-sealed joints and expansion joints.
Bathrooms in smaller places like Gargunnock 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.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
When it is not the sealant
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- Water damage behind tiles that needs a tiler
- A tray or bath that’s cracked
If you are not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer.
What we seal
- Expansion joints

What affects the cost of remedial sealant
Your quote is based on your job. We look at:
- The product the joint needs
- Any working-time requirements on site
- How easy the joints are to reach
- How many areas need sealing
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. Your quote takes all of that into account.
What to tell us for a quote
Photos help, but a description is a good start. Please mention:
- The problem you’ve noticed

- The rough size of the job

What happens if it’s left?
Mould under a bead cannot be reached by cleaning. Removal is the only way to get at it, so the joint can be treated and resealed. Around Gargunnock, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.
What you get with us
- Anti-fungal silicone where joints get wet
- One-year guarantee on every job
- We are fully insured
- Trusted Arbo and Everbuild sealants

Surface by surface
Worktops & kitchens
If a worktop moves when you lean on it, the sealant will keep splitting. It needs fixing down first, which we will point out.
Mouldy bath & shower sealant
Repeat mould generally points to a damp, poorly aired room. Along with resealing, we will mention if the room needs better ventilation.
What remedial sealant looks like in Gargunnock
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. Private landlords in Scotland must be registered and meet the Repairing Standard, which covers keeping fixtures and fittings in a reasonable state of repair. Failed sealant around a bath or shower is worth sorting between tenancies.
Homes close to Parish Church include some older properties, and walls and floors in older homes can move, and sealant and grout show it first.

Common problems we fix in Gargunnock
All sealant wears out eventually. Over the years it shrinks, hardens and gets colonised by mould, especially in damp, poorly aired rooms. At that point it has to come out.
It’s worth asking for a quote if you see:
- Dark patches showing through the sealant
- Wide, uneven beads that look worse than the old ones
- Decorators’ caulk around a bath or shower
- Floor or wall movement joints that have failed
Around Gargunnock, as everywhere, remedial sealant is only as good as the preparation behind it.

Gargunnock: your questions answered
Is there a guarantee on remedial sealant in Gargunnock?
All our work, in Gargunnock and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Is Gargunnock within the area you cover?
Yes. Gargunnock is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. 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 you fix a reseal that hasn’t worked?
Yes. Repeat leaks normally come from over-sealing, movement or water getting in elsewhere, and we deal with the cause first.
I rent my home. Can I book you?
We are happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Will you leave a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Do the sealants smell?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
