Work for landlords, hotels and businesses
We also work for property managers and facilities teams. We can quote a run of properties together.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Bathroom resealing for homes and businesses in Dunoon
Kitchens need the same care as bathrooms. Worktop upstands, sink edges and splashback joints get wet every single day, and water behind a laminate worktop can make it swell. Kitchen joints get a sealant suited to kitchens, colour-matched where it shows. Common call-outs are for water escaping at the shower enclosure and gaps between the worktop and the wall, across kitchen worktops & upstands, sinks & splashbacks and basins & vanity units.
In and around a place like Dunoon, homes range from older stone-built properties to newer houses. Where a building moves, cracked grout and split sealant are generally the first signs.
There’s a 12-month guarantee on every job.

Signs you need bathroom resealing in Dunoon
Not every tube in the shop is meant for a shower. Acrylic caulk and general-purpose sealants are not designed for a joint that is wet every day, so they crack, discolour or grow mould quickly. A bathroom joint needs anti-fungal sanitary silicone.
The most common problems we see are:
- A messy, uneven bead from a previous reseal
- Black spots spreading through the bead
- Water escaping at the shower enclosure
- Water getting behind the kitchen upstand
For site and facilities teams at buildings such as Dunoon Primary School And Janitor's House, we reseal washrooms and kitchens in schools and businesses as well as homes.

Basins & vanity units
The back of a basin gets wet every time someone washes. Corners behind basins are where mould tends to start, and we treat it exactly as we would a bath.
Sinks & splashbacks
Splashbacks in glass, tile or acrylic meet the worktop in a long joint. It’s resealed in white, clear or a colour to suit.
What affects the quote in Dunoon
Call for a quick quote. What matters most is:
- The number and length of the joints
- The product the joint needs
- Any mould that needs treating
- How much old sealant there is and how hard it is to remove
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
Helping us quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Any previous sealing or DIY work
- What’s wrong with the joints now
- How we’d reach the joints
- The rough size of the job
Asking for a quote is easy: tell us what needs doing and where. Photos by email help us understand the job.
Questions from Dunoon
Will you come out to Dunoon?
Yes. Dunoon 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.
Do you work in hotels near Dunoon?
Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.
Can tenants book the work?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Is it OK to put new sealant on top of the old bead?
No. New silicone will not bond to old silicone, so it lifts and traps water and mould underneath. All the old sealant comes out first.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
How long before the new sealant can get wet?
Silicone is touch-dry quite quickly, but it takes longer to cure. Leave it around 24 hours before it gets wet, or follow the cure time we give you.
Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Do you have insurance?
Yes. We’re fully insured, and we’ve been doing sealant work for more than 20 years.
Should I try it myself 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.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
How the visit works
Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it usually takes around two hours for one bath or shower, longer for a whole bathroom. Somewhere like Dunoon may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- Protection goes down around the bath, shower or worktop.
- Old sealant is sliced away and the residue removed.
- We treat any mould and let the joint dry properly.
- Baths are filled first, then anti-fungal sanitary silicone is applied in a colour to suit.
- We finish the joint, clear up and tell you how long to leave it before it gets wet.
How to prepare
- Let us know about earlier repairs to the joints
- Let us know if you’ve seen damp or leaks
- Tell us if parking is tricky

Dunoon homes and their sealant
Dunoon 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. Dunoon has hotels and guest accommodation nearby. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room.
For an older house near a landmark such as St John’s Church (Dunoon), older homes can move a little, which is hard on rigid grout and tired sealant. If you let a flat or house near Inverkip station, fresh sealant around the bath, shower and sink between tenancies helps a property present well and keeps leaks at bay.
Dunoon (Gaelic: Dùn Obhainn) is about 6 miles west of Greenock, in Argyll and Bute. Dunoon gets the same service as everywhere we cover: old sealant removed completely, careful preparation and a one-year guarantee. Dunoon is one of 118 places in Argyll and Bute we cover. Glasgow is on our list too, around 26 miles away.
Postcode districts we cover here for bathroom resealing: PA23. That includes homes and businesses on Queen Street, Queens Court and Pilot Street.

Nearby, we also carry out bathroom resealing in Kirn (1 mile north-east), Hunters Quay (1 mile north-east), Bullwood (2 miles south), Sandbank (2 miles north) and Strone (2 miles north).

Being one of Argyll and Bute’s larger places, Dunoon has homes, rented property and businesses of every kind. If you’re somewhere remote, the job takes a little more planning.

When it is not the sealant
New sealant can’t fix everything, and we’d rather say so up front. It will not solve:
- Cracks in the tray itself rather than the joint
- Failed grout lines across the wall
- A tray that rocks until it’s re-bedded
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly before booking.
