Remedial sealant & repairs in North Roe, Shetland Islands
Remedial sealant across North Roe and nearby, with every bit of old sealant taken out first.
- Repeat leaks from the same joint
- Black mould underneath the bead
- Products that weren’t meant for the joint
How to look after the new joints
To keep the joints looking good and working properly:
- Never fill a movement joint with mortar or grout
- Air the bathroom so the sealant can dry
- Find out why the sealant failed first
- Keep bleach and abrasives off the bead
Watch the joint over the first few weeks, particularly where the original failure was caused by movement. Should anything change, drop us a line at info@mrmastic.co.uk.
Warning signs: sealant lifting at the ends, a second bead visible on top of the first, black mould under the silicone, or stains below a bathroom. Any of them means it’s time for remedial work.
Remedial sealant in North Roe, done properly
Removing failed sealant is the hardest part of the job. We cut out every layer, clear the residue and degrease the surfaces, taking care not to scratch the surfaces around it. Only then can new sealant bond. Common call-outs are for sealant applied over old sealant that has lifted and smears and lumps from a botched reseal, across shrunken worktop sealant, mouldy bath & shower sealant and expansion joints.
Bathrooms in smaller places like North Roe work just as hard as those in the cities. Limescale is less of a problem with Scotland’s generally soft water, but mould still takes hold in damp sealant and grout.
Every job comes with a one-year guarantee.

Why it’s worth doing now in North Roe
A failed seal rarely means a new bathroom. If the bath, tray and tiles are sound, remedial resealing generally puts it right. Where something else has failed, you’ll hear it from us. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.

Landlord and commercial work in North Roe
In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed 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.
North Roe homes and their sealant
North Roe 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. Island jobs need planning around ferries and the weather, so the more notice, the better.
Around North Roe, as everywhere, remedial sealant is only as good as the preparation behind it.
North Roe is in the Shetland Islands. Across the ZE2 area, we can carry out remedial sealant at your property. North Roe is one of 63 places in the Shetland Islands where we work for remedial sealant.
All of ZE2 is covered for remedial sealant, from the main roads to the quietest streets. If you need remedial sealant at a property on Mid Gard, Anniesland and Bayview or anywhere close by, we can help. Close by, we work in Ollaberry (5 miles south), Hogaland (6 miles south), Urafirth (8 miles south-west), Hillswick (9 miles south-west) and Braehoulland (10 miles south-west). Island and remote addresses take a little more planning, so tell us where you are when you ask for a quote.

Surface by surface
Mouldy bath & shower sealant
Black mould inside the bead won’t scrub out. All of it comes out, and the joint is treated and dried before anti-fungal sanitary silicone goes in.
Windows & doors
Smeared or badly matched mastic can be cut out and redone neatly, matched to the frame colour.
Signs you need remedial sealant in North Roe
Some joints fail because water is reaching them from behind. A leaking valve, a failed waste or cracked grout feeds water behind the bead, and the sealant lifts or goes mouldy from underneath.
Look out for these signs:
- A shower that leaks however often it’s resealed
- Floor or wall movement joints that have failed
- Products that weren’t meant for the joint
- Sealant applied over old sealant that has lifted
In the older streets around Methodist Church, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

What happens on the day
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. It normally takes a few hours for most joints, depending on how much old sealant has to come out. Around North Roe, distance and access matter more than parking. Let us know how to find you and how to reach the joints.
- We start by checking the joint for movement, leaks and the reason it failed.
- We strip the joint completely, removing any layers below.
- The joint is cleaned, treated for mould and left to dry.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- We tool the joint and tell you about anything else that needs attention.
Getting ready for the visit
- Tell us about any water getting in
- Tell us if parking is tricky
- For business premises, tell us about site rules or sign-in

North Roe questions
What guarantee comes with remedial sealant in North Roe?
All our work, in North Roe and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Is North Roe within the area you cover?
Yes, we do. We work across all of Scotland, islands included, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is there any odour?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
Do I have to be there?
It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
When is the sealant fully cured?
It depends on the product and the temperature. Before we leave, we will tell you the cure time.
Do you work for letting agents?
Yes, often. Several properties can go on one quote, and between tenancies is a good time for the work.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us and we are fully insured.
