Where the photographs don’t tell the full story, we arrange a site visit.

Searching for sealant specialists in Dunoon? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
A lot of what we do in Dunoon is replacing sealant that has done its years: split, chalky or peeling, with leaks or mould starting behind it.
In smaller Scottish places like Dunoon, commercial buildings are often hotels, pubs, shops, schools, surgeries and farm or estate buildings put to new use. Each has kitchens, washrooms and frames that depend on sound joints.

Our process
Inspect, seal, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Where we can, we combine work around Dunoon with other jobs nearby, to make the most of each trip. Tell us how flexible your dates are.
- We start with the evidence: photographs, drawings or a look on site.
- A fixed quote follows, with removal and preparation included.
- Sequence, access and working times are settled before the first joint is touched.
- The failed sealant comes out and the faces are prepared, with primer where required.
- Backing goes in, the new sealant is laid and tooled, and the area is left neat.
- We hand back each area with its cure time and our 12-month guarantee.
What we need from you
- Confirm the product named in the specification
- Point out parking and an unloading spot
- Send asbestos survey details if the building is pre-2000
Getting a fixed quote
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to give us a call on 01277 525 020 or email us with what you know.

Commercial sealant contractors around Dunoon: how the place shapes the job
With the shore within about 1 mile, Dunoon counts as a coastal location. For shops, hotels and offices, that means frontage and frame joints that weather faster than they would inland. A matched colour is only half the brief on an exposed frontage. Being in the west of Scotland, Dunoon gets more rain than eastern areas. Outside sealing needs dry spells and a programme that can move a little. Weather-facing frames tend to need resealing before the sheltered ones
Premises within reach of Inverkip station (to the south-east of Dunoon) often have busy frontages where joints are seen by everyone passing.
Dunoon (Gaelic: Dùn Obhainn) is about 6 miles west of Greenock, in Argyll and Bute. We send applicators to Dunoon for sealant joints. Dunoon is one of 124 places we cover in Argyll and Bute for sealant joints. We also cover Glasgow, around 26 miles from Dunoon.
Commercial sites across PA23 are covered. Among the streets we cover are Queen Street, Queens Court and Pilot Street. Dunoon sits on or close to the A815 and A885, useful when we plan access and materials. Nearby places we also cover include Kirn (1 mile north-east), Hunters Quay (1 mile north-east), Bullwood (2 miles south), Sandbank (2 miles north) and Strone (2 miles north) for sealant joints. Bigger towns within reach include Helensburgh (9 miles north-east), Rothesay (10 miles south-west), Cardross (11 miles east), Rhu (7 miles north-east), Garelochhead (10 miles north-east) and Port Bannatyne (9 miles south-west). Dunoon ranks among the main centres of Argyll and Bute, with offices, shops, schools and other public and commercial buildings, and we cover them all. Remote and island addresses take more planning, from travel and ferries to the weather, so give the site location in your enquiry.
Near you in Dunoon
Around Dunoon, our work takes us to commercial buildings near Dunoon Grammar School and the streets around them. For rail, the closest station is Inverkip station, roughly 3.9 miles south-east. Other landmarks nearby include Dunoon Castle (0.6 miles south) and Castle House Museum (0.6 miles south). The countryside around Dunoon includes Loch Loskin.
What we’re called out for in Dunoon
Resealing over the top is a false economy we come across often. Fresh sealant won’t stick to the old bead underneath. Getting back to a clean joint then means removing every layer.
Common reasons buildings call us in:
- Mouldy silicone around WCs, urinals and vanity tops
- Smeared sealant across finishes from a rushed job
- Damp patches where an external joint has failed
- External beads that have gone brittle and cracked
A hotel such as Argyll Hotel (to the south of Dunoon) shows how much sealant a hospitality building has on show, from bathroom joints to the bar.
What your quote should include
- The terms of the workmanship guarantee
- Which product they’ll use, and why it suits the joint
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Whether old or failed sealant will be cut out, not overlaid
Leave it or put it right?
Putting off a reseal normally moves the cost rather than avoiding it. Once water gets behind the seal, finishes and ceilings underneath are next, which brings decorators and flooring contractors into the repair. Resealing while only the sealant has failed keeps the job small. Around smaller places like Dunoon, halls, stores and seasonal buildings may not be checked often, so a failed joint has time to cause damage. Early resealing prevents it.
The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site rules also count.
Why appoint us
- Fully insured, including public liability cover
- Matching to RAL references, product permitting
- One phone line for London, the South East and Scotland
- Colour agreed before work starts
What sealant work can’t fix
Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be one of these:
- Old mastic that tests positive for asbestos
- A dripping trap, valve or pipe behind a fitting
- Faulty windows rather than failed perimeter sealant
If you are not sure, just give us a call on 01277 525 020 or use the quote form and we will give you a straight answer.
Where we work in Dunoon

What the job involves on each surface
Commercial kitchens and tea points
Gaps and ragged beads trap dirt that cleaning can’t reach. We seal to a neat, cleanable finish and work around service times you agree with us.
Window and door perimeters
Internally, window boards and frame edges often have decorators’ caulk or silicone that has cracked. We use a paintable product where decorating follows and a silicone where it doesn’t.
How the quote is worked out
There’s no standard rate for sealant work, since sites vary so much. What we look at:
- How much there is to seal
- Travel to remote or island sites
- The product specified
- Phasing around occupants
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
Sending details for a quote
For an accurate fixed quote, we need to understand the site. Useful things to include:
- Specification clauses that apply
- Anything awkward about access or site hours
- A wide shot and a close-up of the area
- Whether the building will be occupied during the work
A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or phone 01277 525 020 or email a schedule or drawings if you’d rather talk the job through.
Your questions answered
Do hotels near Dunoon have to close for sealant work?
Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. We agree the order of rooms and the timings with you before we start.
Is Dunoon too far out for you?
No. Small places get the same service as large ones. We cover the whole of Scotland. We plan jobs in smaller places so return trips are kept to a minimum.
Could the old sealant in an older building contain asbestos?
It’s possible in older buildings, especially those built before 2000. Before cutting anything out, we ask for the asbestos register or survey, and anything suspect is left until it has been tested.
When is resealing likely to be due?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
What do you need from us to quote?
Start with whatever information is to hand. Questions or a site visit follow where needed, and then a fixed quote for the agreed scope.
Are your applicators CSCS-carded?
Yes. If you need card details for site access, tell us and we’ll confirm them with the quote.
Which site documents can you send us?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We’re CHAS accredited and a Constructionline member, with five million pounds of public liability insurance.
