How we handle remedial sealant in Carloway
Two decades of sealant work means we recognise most failures quickly. We are ARBOMaster approved and fully insured, and remedial work carries our 12-month guarantee. If you’re dealing with sealant that came away because the surface wasn’t prepared and wide, uneven beads that look worse than the old ones, we can put it right, whatever the surface.
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. The journey and access are simply planned in advance.
The work is covered for a year after we finish. If anything isn’t right with it, send an email to info@mrmastic.co.uk.

When it is not the sealant
In fairness, there are a few things sealant will not fix:
- A tray or worktop that needs refixing first
- A cracked shower tray or bath (that needs repair or replacing)
- Older mastics that may need an asbestos check before removal
If you are not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer before booking.
Joints and surfaces we work on
- Mouldy bath & shower sealant
- Leaking tray & enclosure joints
- Failed movement joints
- Botched or over-sealed joints
- Shrunken worktop sealant
- Expansion joints
How it works
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. It generally takes a few hours for a typical bath or shower, longer where several layers have been applied. Outdoor work around Carloway depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Old beads and residue are removed down to clean surfaces.
- We treat any mould and dry the joint thoroughly.
- We reseal with a product suited to the joint, backed where needed.
- The joint is tooled and you’re told about anything else we found.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Mention any leaks or damp you’ve noticed
- For indoor joints, keep the area dry beforehand if you can

Carloway homes and their sealant
Carloway is within about 2 miles of 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. Scottish Water supplies are generally soft, so limescale is less of a problem than in hard-water areas. But mould still grows into sealant and grout in a room that doesn’t dry out.
Whether the job is in Carloway itself or nearby, the right material for each joint matters as much as a neat finish.
Carloway (Gaelic: Càrlabhagh) is in Na h-Eileanan Siar. From the centre of Carloway to the outskirts, remedial sealant is available for homes and businesses alike. We cover 87 towns and villages across Na h-Eileanan Siar.

Common problems we fix in Carloway
Even good sealant ages. Over the years it shrinks, hardens and gets colonised by mould, faster where ventilation is poor. Then the only fix is removal and a new bead.
Look out for any of the following:
- Decorators’ caulk around a bath or shower
- Torn expansion joints
- Kitchen joints letting water behind the worktop
- Dark patches showing through the sealant
In and around Carloway, as anywhere, good remedial sealant starts with a clean, dry, properly prepared joint.

How to look after the new joints
Looking after new joints is easy:
- Never seal over old silicone
- Use a soft cloth, not a scourer, on silicone
- Keep the room well ventilated
- Never fill a movement joint with mortar or grout
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.
A failing joint rarely gets better on its own. Every shower or downpour sends more water through, into whatever is behind or below. Sorting it early limits the damage.
Questions from Carloway
Is there a guarantee on remedial sealant in Carloway?
All our work, in Carloway and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Do you cover smaller places like Carloway?
Yes, smaller places are covered as well as towns. We work across all of Scotland, including the islands, where work is planned around ferry crossings. Just mention lanes, gates or anything else about the route when you book.
Do you have insurance?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Can you take off two layers of silicone?
Yes. Both layers come out; new silicone does not bond to old silicone, which is why over-sealing fails.
Do you work for letting agents?
Yes. As well as householders, we work for landlords, agents, businesses and hotels in Carloway.
What happens if the problem is the tray or the plumbing?
We’ll tell you. A cracked tray, faulty valve or leaking waste needs a different trade, so we won’t pretend it will.
Can old silicone be taken off without scratching the tiles?
Yes. We take our time over removal, particularly on softer surfaces like acrylic.
I rent my home. Can I book you?
We can work for tenants, landlords or agents. Just make sure your landlord agrees.
For landlords and businesses
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll give you a quote.
Hotels need rooms back in use, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
Leave it or put it right?
Ripping out a bathroom is not normally needed. If the bath, tray and tiles are sound, remedial resealing generally puts it right. Where something else has failed, you will hear it from us. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, send an email to info@mrmastic.co.uk and we will give you an honest view and a quote.
