Kirn: your questions answered
Do you take on hotel work around Kirn?
Yes, we work for hotels as well as homes and businesses. Rooms can be done a few at a time, so the building stays open.
Is Kirn within the area you cover?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you guarantee remedial jobs?
Yes. Our one-year guarantee covers the work.
What happens if the problem is the tray or the plumbing?
We will tell you. A cracked tray, faulty valve or leaking waste needs a different trade, so we won’t pretend it will.
Do you fix expansion and movement joints?
Yes. Failed movement joints are cut out and resealed with backing and a flexible sealant suited to the movement.
Where do you work from?
We’re a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
What does remedial sealant cost?
Every job is different, so each one gets its own quote. To get one, send an email to info@mrmastic.co.uk with a short description of the job.
Do you have insurance?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Remedial sealant in Kirn
A movement joint stops working when its sealant splits or sets hard. The old sealant comes out and backing goes in to control the depth, before resealing with a flexible product suited to the movement. If you have thick, messy sealant smeared over tiles and a second bead peeling off the first, we can help, on mouldy bath & shower sealant, shrunken worktop sealant and failed movement joints alike.
Being further from a city does not change the work: everything old is cut out, the joints are cleaned and dried, and new sealant or grout goes in. We just plan the journey and access beforehand.
Every job comes with a one-year guarantee.

Common problems we fix in Kirn
Some joints fail because water is reaching them from behind. A slow leak behind the tiles soaks the joint from the back, so the silicone goes mouldy or lets go.
It’s worth asking for a quote if you see:
- Movement joints that have split or pulled away
- Worktop sealant that has shrunk and split
- Smears and lumps from a botched reseal
- A shower that leaks however often it’s resealed
If you let a flat or house near Gourock station, botched sealant from a previous quick fix is easier to strip out between tenants.

What remedial sealant looks like in Kirn
Kirn is close to the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, 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. Mould is another matter: a bathroom that stays damp still turns sealant and grout black.
In the older streets around Kirn Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them. For site and facilities teams at buildings such as Kirn Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
Kirn is about 4 miles west of Gourock, in Argyll and Bute. From the centre of Kirn to the outskirts, remedial sealant is available for homes and businesses alike, from flats and houses to offices and hotels. Our Argyll and Bute coverage runs to 118 places, Kirn among them. Glasgow is on our list too, about 26 miles from Kirn.
All of PA23 is within our area for remedial sealant, from the main roads to the quietest streets. We cover properties on Ard Mhor, Kirn Brae and Ash Gardens. Nearby, we also carry out remedial sealant in Hunters Quay (1 mile north-east), Dunoon (1 mile south-west), Sandbank (2 miles north-west), Strone (2 miles north) and Bullwood (2 miles south-west).

What the job involves on each surface
Movement & expansion joints
Movement joints in floors, walls and façades need a flexible sealant set to the right depth. Failed sealant is cut out, backing rod or tape is fitted and the joint resealed.
Mouldy bath & shower sealant
Mould often spreads under the bead as well as through it. Once it’s all removed, the joint is treated.
The process
There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes a few hours, depending on how many layers have to come out from start to finish. Outside jobs in Kirn need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- 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.
- We treat any mould and dry the joint thoroughly.
- The right product goes in, with backing where the joint moves.
- The joint is tooled and you are told about anything else we found.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Mention any tricky access
- Mention any sign-in or site rules at work premises

How we quote for remedial sealant
We do not publish a price list, because jobs vary so much. The quote depends on:
- Whether old sealant or filler has to be cut out
- Access and height
- The number of rooms or windows
- When we can work, for business premises
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please email us at info@mrmastic.co.uk.
Asking for a quote
To make quoting easier, let us know:
- A few pictures by email, if you can
- How many joints, rooms or windows are involved
- If someone has resealed it before
- Access, such as stairs, a lift or height
For a quick quote, get us on the phone, or send an email if you’d rather. Describe what needs sealing and we will explain what’s involved and send you a clear quote.
When something else is needed
In fairness, some problems need a different trade:
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- A tray or worktop that needs refixing first
- A tray or bath that is cracked
If in doubt, drop us a line at info@mrmastic.co.uk and we will say what we think.

Landlord and commercial work in Kirn
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
We work for landlords and letting agents as well as householders. Sealant work between tenants keeps a property looking cared for before the next move-in.
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
