Remedial sealant in Portincaple
Some sealant jobs are not a simple reseal, because someone has already had a go. New sealant over old, smeared beads, unsuitable products and hidden mould all have to come out. Typical jobs include a second bead peeling off the first and a shower that leaks however often it’s resealed, on leaking tray & enclosure joints, botched or over-sealed joints and expansion joints.
In and around a place like Portincaple, homes range from older stone-built properties to newer houses. Older buildings can move a little, and that shows first in cracked grout and split sealant.
We stand behind the work with a one-year guarantee.

Why it’s worth doing now in Portincaple
DIY removal often leaves scratches and a film of residue, and the residue left behind stops the next bead bonding. Careful removal is most of a remedial job. In a place like Portincaple, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.

How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Don’t point over movement joints
- Never seal over old silicone
- Have loose fittings fixed before resealing
- Find out why the sealant failed first
Don’t let anyone seal over it later. Over-sealing is how many remedial jobs start, so the old bead should always come out first.
Mould trapped under over-sealed joints spreads unseen. By the time it shows through, the joint is well past saving.
Different surfaces, different methods
Mouldy bath & shower sealant
Mould can sit behind the silicone, not just in it. We treat the exposed joint once the bead is out.
Movement & expansion joints
A movement joint must be able to stretch. We remove the failed sealant, fit backing and reseal with a low-modulus product.
What remedial sealant looks like in Portincaple
Portincaple is within about 1 mile of the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, 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 does not dry out.
Around Portincaple, as everywhere, remedial sealant is only as good as the preparation behind it.

What we do, step by step
You don’t need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the work takes a few hours for most joints, depending on how much old sealant has to come out in most cases. Outside jobs in Portincaple need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Each layer is cut out and the residue cleaned off.
- Mould is treated and the joint dried.
- The right product goes in, with backing where the joint moves.
- We finish neatly and point out anything that needs another trade.
Before we arrive
- Mention any tricky access
- Tell us about any water getting in
- Where the joints are inside, avoid wetting them before we arrive

That depends on how many layers there are and how many joints. You’ll have a timescale before any work begins.

Signs you need remedial sealant in Portincaple
Some joints fail because water is reaching them from behind. A slow leak behind the tiles soaks the joint from the back, so the silicone goes mouldy or lets go.
Look out for any of the following:
- Worktop sealant that has shrunk and split
- Decorators’ caulk around a bath or shower
- A second bead peeling off the first
- A shower that leaks however often it’s resealed
For landlords with property near Garelochhead station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.
