Remedial sealant in Hoswick, done properly
Two decades of sealant work means we recognise most failures quickly. We’re fully insured ARBOMaster approved applicators, and remedial work carries our one-year guarantee. Common call-outs are for smears and lumps from a botched reseal and worktop sealant that has shrunk and split, on expansion joints, botched or over-sealed joints and failed movement joints.
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. We just plan the journey and access beforehand.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

- Mould in or behind the old joints

Common problems we fix in Hoswick
A lot of failed joints have been sealed over rather than replaced. New silicone cannot stick to the old bead, so the top layer lifts and water and mould collect between the two.
The problems people generally mention when they call include:
- Movement joints that have split or pulled away
- Decorators’ caulk around a bath or shower
- A second bead peeling off the first
- Thick, messy sealant smeared over tiles
Around Hoswick, as everywhere, remedial sealant is only as good as the preparation behind it.

Can tenants book the work?

Do you have insurance?
Yes. We’re fully insured, with over 20 years’ experience in sealant work.
Do I have to be there?
It depends on the job. Inside work needs someone to give us access.
Can landlords and businesses book you?
Yes. We work for householders, landlords, letting agents, businesses and hotels across the Shetland Islands.
Can you remove old sealant without damaging the bath?
Yes. We avoid heavy scraping and use the right cleaner for each surface, so the new sealant bonds cleanly.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before resealing.
How to look after the new joints
Aftercare is simple:
- Keep an eye on the ceiling below the bathroom
- Never seal over old silicone
- Run the fan after every shower
- Use a soft cloth, not a scourer, on silicone
Give the new sealant its full cure time: follow the cure time we give you.
Signs to act on: peeling layers, mould showing through the bead, leaks after showering or cracks in a movement joint. Any of them means it’s time for remedial work.
DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Different surfaces, different methods
Leaking trays & enclosures
If the tray is cracked, or the leak is from the valve or waste, sealant won’t fix it. We will tell you what we find.
Worktops & kitchens
If a worktop moves when you lean on it, the sealant will keep splitting. It needs fixing down first, and we will tell you if we find it.
How the visit works
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes a few hours for most joints, depending on how much old sealant has to come out from start to finish. For a place like Hoswick, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- 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.
- Mould is treated and the joint dried.
- We reseal with a product suited to the joint, backed where needed.
- We finish neatly and point out anything that needs another trade.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- For business premises, tell us about site rules or sign-in
- Tell us if parking is tricky

Remedial sealant around Hoswick
Hoswick is within about 1 mile 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. Scotland’s water is generally soft, so sealant and grout see less limescale than in much of England. But mould still grows into sealant and grout in a room that does not dry out.
Whether the job is in Hoswick itself or nearby, the right material for each joint matters as much as a neat finish.
