Remedial sealant in Longbar, done properly
Remedial work is what we do when sealant has failed or been done badly. New sealant over old, smeared beads, unsuitable products and hidden mould all have to come out before the joint can be done properly. If you have torn expansion joints and sealant peeling off a dusty or damp surface, we can put it right.
A bathroom in a place like Longbar gets the same daily wear as one in a city flat. Limescale is less of a problem with Scotland’s generally soft water, but mould still takes hold in damp sealant and grout.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Can I do it myself?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What we are called out for in Longbar
A lot of failed joints have been sealed over rather than replaced. Silicone doesn’t bond to silicone, so the new layer peels, and damp and mould settle between them.
People usually contact us when they notice something like this:
- Movement joints that have split or pulled away
- Products that weren’t meant for the joint
- Repeat leaks from the same joint
- Mould trapped under a layer of silicone
Rented homes near Glengarnock station change hands often, and botched sealant from a previous quick fix is easier to strip out between tenants.

Is Longbar within the area you cover?

Where are you based?

Can you take off two layers of silicone?
Yes. We cut out all the layers and clean off the film, before resealing with a single bead.
Are you ARBOMaster approved?
Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Do you guarantee remedial jobs?
Yes, for 12 months. Where we have flagged another fault, it needs fixing for the joint to last.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Keep bleach and abrasives off the bead
- Keep an eye on the ceiling below the bathroom
- Never seal over old silicone
- Keep movement joints clear of mortar and paint
Watch the joint over the first few weeks, particularly where the original failure was caused by movement. Should anything change, email us at info@mrmastic.co.uk.
If a joint has failed more than once, stop resealing it. Get the cause found first, otherwise the next attempt will fail too.

Longbar homes and their sealant
In Scotland, private landlords have to 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. 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 does not dry out.
For an older house near a landmark such as Kilbirnie Auld Kirk, older homes can move a little, which is hard on rigid grout and tired sealant.

How the job changes by surface
Worktops & kitchens
If a worktop moves when you lean on it, the sealant will keep splitting. It needs fixing down first, which we’ll point out.
Over-sealed & botched joints
Botched joints sometimes have damaged edges from earlier scraping. We work carefully to avoid adding to it, and tell you about any damage we find.
Leave it or put it right?
Repeat failures have a cause. Taking time to find the cause, whether it’s movement, a leak or the wrong product, is what stops it happening again. In a place like Longbar, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
A failed joint rarely gets cheaper to fix by waiting. If you are not sure whether it needs doing, send an email to info@mrmastic.co.uk and we’ll give you an honest view and a quote.
