Surface by surface
Worktops & kitchens
Kitchen joints often have grease and cleaning residue deep in them, so we spend extra time cleaning.
Mouldy bath & shower sealant
Mould often spreads under the bead as well as through it. Once it’s all removed, the joint is treated so the new sealant starts clean.
Remedial sealant in Dunvegan
Remedial jobs in Dunvegan usually fall into a few patterns: sealant over sealant, mould under the bead, leaks that come back and movement joints that have split. We strip each one back and start from scratch. Typical jobs include torn expansion joints and thick, messy sealant smeared over tiles, on failed movement joints, botched or over-sealed joints and mouldy bath & shower sealant.
For a place like Dunvegan, the job is the same as anywhere: old material out, joints cleaned and dried, and a fresh, even finish. The journey and access are simply planned in advance.
Every job is covered by a one-year guarantee, wherever you are in Highland.

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Never fill a movement joint with mortar or grout
- Never seal over old silicone
- Air the bathroom so the sealant can dry
- Find out why the sealant failed first
Keep an eye on the joint at first, particularly where the original failure was caused by movement. Should anything change, send an email to info@mrmastic.co.uk.
Movement joints that have split let water into the structure, and the longer it’s left, the more the joint edges break down. A joint with sound edges is far easier to reseal.
What happens on the day
We bring everything the job needs with us. Once we have agreed what’s being done, the area is protected and the work begins. Most jobs take a few hours for most joints, depending on how much old sealant has to come out. Around Dunvegan, distance and access matter more than parking. Tell us how to find the property and how to reach the work.
- 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.
- The right product goes in, with backing where the joint moves.
- We finish neatly and point out anything that needs another trade.
How to prepare

- Leaks from a shower valve, waste or pipework (a plumber’s job)
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we will tell you honestly before you book.

Remedial sealant in Dunvegan: local notes
Dunvegan 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. Private landlords in Scotland must be registered and meet the Repairing Standard, which includes keeping fixtures and fittings in reasonable repair. Failed sealant around a bath or shower is worth sorting between tenancies.
For jobs in and around Dunvegan, choosing the right material for each joint is as important as a tidy finish. Around Dunvegan, as everywhere, remedial sealant is only as good as the preparation behind it.

What happens if it’s left?
Mould under a bead cannot be reached by cleaning. The layers have to come out, and the joint treated and dried before resealing. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Call for a quick quote and we will go through it with you.

DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
