Remedial sealant in Dounby
Getting old sealant out properly is slow, careful work. Every layer is cut out, the residue cleaned off and the joint degreased, without scratching tiles, trays or frames. New sealant only bonds to a clean, dry joint. If you have thick, messy sealant smeared over tiles and worktop sealant that has shrunk and split, we can put it right.
In and around a place like Dounby, homes range from older stone-built properties to newer houses. Older buildings can move a little, and that shows first in cracked grout and split sealant.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

How the visit works
Every visit runs the same way: we check the joints, protect the area around them, carry out the job and tidy away. Most jobs take a few hours for a typical bath or shower, longer where several layers have been applied. Outside jobs in Dounby need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- Surrounding tiles, trays and frames are protected first.
- Every layer of failed sealant is stripped out.
- We clean and degrease the joint and look for signs of movement or water.
- Once dry, a suitable sealant is applied and tooled.
- You get the cure time and our view on why the joint failed.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Mention if the joints have been sealed before
- Where the joints are inside, avoid wetting them before we arrive

Bathrooms and kitchens in Dounby
Dounby 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. Island jobs need planning around ferries and the weather, so the more notice, the better.
Around Dounby, as everywhere, remedial sealant is only as good as the preparation behind it.
Dounby is about 12 miles north-west of Kirkwall, in the Orkney Islands. We provide remedial sealant to householders, landlords and businesses in Dounby and nearby, as part of our work across the Orkney Islands. Our area takes in 51 places across the Orkney Islands.
Every address in KW17 is covered for remedial sealant, from the main roads to the quietest streets. You will find streets such as Flett's Park, Back Road and Hillside Road, and we cover them all.

When to call us in Dounby
Water from somewhere else can ruin a good seal. A leaking valve, a failed waste or cracked grout feeds water behind the bead, so the silicone goes mouldy or lets go.
The most common problems we see are:
- Products that weren’t meant for the joint
- A shower that leaks however often it’s resealed
- Over-sealed joints coming away
- Mould trapped under a layer of silicone
For jobs in and around Dounby, choosing the right material for each joint is as important as a tidy finish.
Questions to ask before booking
- What product goes in the joint
- Whether they’re fully insured
- Whether VAT is included
- Who turns up on the day

We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.

Your questions about remedial sealant in Dounby
What guarantee comes with remedial sealant in Dounby?
All our work, in Dounby and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Do you cover Dounby for remedial sealant?
Yes. Our work covers the whole of Scotland, and Dounby is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job, and we will send you a clear quote.
Can you quote for more than one area?
Yes. Just list everything you need and you will get one quote.
Where are you based?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
Do the sealants smell?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Can you match the sealant colour?
We’ll suggest a colour to suit the surroundings, from white and clear to greys and other shades. The product needed can limit the range.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status, and we are fully insured.
What the job involves on each surface
Movement & expansion joints
A sealant stuck to the back of the joint can’t stretch. Backing rod or bond-breaker tape prevents it, so the sealant grips the two sides only.
Over-sealed & botched joints
A thick bead smeared across tiles often hides mould or gaps. Taking it back shows what’s underneath, then reseal neatly.
When something else is needed
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Failed tanking or loose tiles behind the sealant
- Sealant in an older building that needs testing for asbestos first
- Cracks in the fitting rather than the joint
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly before booking.

DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
What happens if it’s left?
Repeat failures have a cause. Finding it, whether movement, water from elsewhere or an unsuitable product, ends the cycle. In a place like Dounby, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
