Gergask Remedial Sealant
Failed sealant joints in Gergask need attention? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Products that weren’t meant for the joint
- Beads that never stuck properly
- Worktop sealant that has shrunk and split
How we handle remedial sealant in Gergask
Not every leak is a sealant leak. Cracked trays, leaking wastes and faulty valves often look like a sealant problem. When the fault is elsewhere, we say so instead of resealing for the sake of it. If you are dealing with black mould underneath the bead and repeat leaks from the same joint, we can put it right.
Bathrooms in smaller places like Gergask 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.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
Signs you need remedial sealant in Gergask
Silicone only bonds to surfaces that are clean and dry. Residue, moisture or dust left in the joint weaken the bond, so it starts lifting sooner than it should.
People generally contact us after spotting something like this:
- Sealant that came away because the surface wasn’t prepared
- Worktop sealant that has shrunk and split
- Smears and lumps from a botched reseal
- Torn expansion joints
Homes close to Laggan Parish Church include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them.

Remedial sealant in Gergask: local notes
Scotland’s water is generally soft, so sealant and grout see less limescale than in much of England. Mould is another matter: a bathroom that stays damp still turns sealant and grout black. 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.
In and around Gergask, as anywhere, good remedial sealant starts with a clean, dry, properly prepared joint.

Why act early in Gergask
Ripping out a bathroom is not normally needed. If the bath, tray and tiles are sound, remedial resealing usually puts it right. If they’re not, we’ll tell you. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.

Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Keep an eye on the ceiling below the bathroom
- Never fill a movement joint with mortar or grout
- Never seal over old silicone
- Don’t wait for a small gap to become a leak
Watch the joint over the first few weeks, particularly where the original failure was caused by movement. If anything changes, just email us at info@mrmastic.co.uk.
If a joint has failed more than once, stop resealing it. Have someone find out why, or the next bead will go the same way.
When it is not the sealant
It helps to know what we cannot do:
- Failed tanking or loose tiles behind the sealant
- 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 booking.

How the visit works
You do not need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the job takes a few hours for most joints, depending on how much old sealant has to come out for a typical job. For a place like Gergask, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- Surrounding tiles, trays and frames are protected first.
- The botched or failed sealant is cut away completely.
- The joint is degreased and checked for movement and leaks.
- Once dry, a suitable sealant is applied and tooled.
- We give you the cure time and explain what caused the failure.
Preparing for the visit
- On commercial sites, let us know about site rules
- Move anything stored near the joints
- For indoor joints, keep the area dry beforehand if you can

How the job changes by surface
Windows & doors
Smeared or badly matched mastic can be cut out and redone neatly, in a colour that suits the frame.
Mouldy bath & shower sealant
Mould that has grown into silicone does not clean out for good. All of it comes out, and the joint is treated and dried ahead of a new anti-fungal bead.
