Remedial sealant in Port Mholair
Getting old sealant out properly is slow, careful work. We cut out every layer, clear the residue and degrease the surfaces, taking care not to scratch the surfaces around it. New sealant only bonds to a clean, dry joint. Typical jobs include movement joints that have split or pulled away and sealant peeling off a dusty or damp surface, across leaking tray & enclosure joints, botched or over-sealed joints and expansion joints.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses. Where a building moves, cracked grout and split sealant are normally the first signs.
We stand behind the work with a 12-month guarantee, so you are covered after we’ve gone.

What the job involves on each surface
Over-sealed & botched joints
Thick, smeared sealant looks messy and hides problems. We strip it back so we can see the joint.
Worktops & kitchens
Shrunken worktop sealant leaves a gap that lets water into the back edge. We strip it, degrease the joint and reseal.
When to call us in Port Mholair
Even good sealant ages. Mould grows into the silicone, the surface hardens and the bead shrinks, especially in damp, poorly aired rooms. At that point it has to come out.
Any of these means the joints need attention:
- Caulk or the wrong sealant used in a wet area
- Torn expansion joints
- A second bead peeling off the first
- Gaps opening along the back of the worktop
Around Port Mholair, as everywhere, remedial sealant is only as good as the preparation behind it.
Questions to ask before booking
- How long to leave it before use
- Whether they seal over old material or remove it
- What guarantee comes with the work
- Whether the sealant suits the joint
The process
There isn’t much for you to do on the day. Show us the job and we’ll take it from there. The job generally takes a few hours for most joints, depending on how much old sealant has to come out from start to finish. Outside jobs in Port Mholair need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- We protect the surfaces around the joint.
- Every layer of failed sealant is stripped out.
- We clean and degrease the joint and look for signs of movement or water.
- New sealant goes in once the joint is dry, and is tooled smooth.
- You get the cure time and our view on why the joint failed.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- Tell us if parking is tricky
- Plan for the work area to be out of bounds to pets and children

Keeping the joints in good condition
After the cure time, these simple habits help:
- Ask why a joint failed before redoing it
- Always have old sealant cut out, not covered
- Check trays and worktops do not move
- Clean sealant with mild products only
Leave the new joint to cure fully before it gets wet or moves: generally around 24 hours, or as long as we advise.
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.
Remedial sealant in Port Mholair: local notes
Port Mholair is close to 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. Work on the islands has to be planned around ferry crossings and the weather, so the more notice, the better.
If you look after a building such as Aird Primary School, washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes.
Port Mholair (Gaelic: Portvoller) is in Na h-Eileanan Siar. From the centre of Port Mholair to the outskirts, remedial sealant is available for homes and businesses alike. Port Mholair is one of 87 towns and villages in Na h-Eileanan Siar where we work for remedial sealant.

Port Mholair questions
Is remedial sealant in Port Mholair guaranteed?
Every job comes with our 12-month guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Is Port Mholair within the area you cover?
Yes, we do. Our work covers the whole of Scotland, islands included, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you work on commercial sites?
Yes, regularly. We can plan bigger jobs in stages.
Someone sealed over the old bead. Can you fix it?
Yes. We cut out all the layers and clean off the film, before resealing with a single bead.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We will give you the cure time for the product we used.
Can failed expansion joints be resealed?
Yes. If a joint has been filled with mortar or rigid filler, we rake it out where possible, then the joint is sealed properly.
How do I get a quote for remedial sealant in Port Mholair?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before work begins.
Is it worth trying it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- A bath, tray or worktop that moves until it’s properly fixed
- Failed tanking or loose tiles behind the sealant
- Leaks from a shower valve, waste or pipework (a plumber’s job)
If in doubt, drop us a line at info@mrmastic.co.uk and we’ll say what we think before you book.
