In and around Portvoller, as anywhere, good remedial sealant starts with a clean, dry, properly prepared joint.

How we handle remedial sealant in Portvoller
The wrong product in the wrong joint won’t last, however tidy it looks. Out it comes, and in goes a sealant suited to the job. We work on failed movement joints, leaking tray & enclosure joints and mouldy bath & shower sealant, and the jobs we see most are smears and lumps from a botched reseal and torn expansion joints.
Being further from a city doesn’t change the work: old material out, joints cleaned and dried, and a fresh, even finish. The journey and access are simply planned in advance.
All of our work is guaranteed for twelve months.

Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.

Keeping the joints in good condition
After the cure time, these simple habits help:
- Deal with small splits early
- Never seal over old silicone
- Keep the room well ventilated
- Keep an eye on the ceiling below the bathroom
Go easy on the new sealant: a mild cleaner and a soft cloth, with no blades or scourers.
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.
Signs you need remedial sealant in Portvoller
How a joint is built matters as much as the product. A bead bonded on three sides, or laid too thick, cannot flex, so it tears when the joint moves. Backing rod or bond-breaker tape prevents it.
Common reasons people contact us are:
- Sealant that came away because the surface wasn’t prepared
- Leaks that keep coming back after resealing
- Movement joints that have split or pulled away
- Decorators’ caulk around a bath or shower
Managing a site like Aird Primary School? Then we reseal washrooms and kitchens in schools and businesses as well as homes.

How it works
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for most joints, depending on how much old sealant has to come out. Somewhere like Portvoller may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We start by checking the joint for movement, leaks and the reason it failed.
- Every layer of old sealant is cut and cleaned out.
- Next, any mould is treated and the joint dried.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- The new joint is tooled neatly and we explain anything else we found.
Getting ready for the visit
- Mention if the joints have been sealed before
- Tell us if parking is tricky
- Move anything stored near the joints

- A leaking trap, valve or supply pipe

FAQs for Portvoller
Do you cover Portvoller for remedial sealant?
Yes, Portvoller is within the area we cover. We work across all of Scotland. Just send an email to info@mrmastic.co.uk with a few details of the job, and we’ll send you a clear quote.
Do you cover smaller places like Portvoller?
Yes, we do. Our work covers the whole of Scotland, islands included, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do I need to be at home?
Access is agreed with you when the job is booked. Indoors, that generally means someone at home.
Can I add another job to the visit?
Yes. Just list everything you need and we will quote it together.
My shower still leaks after a reseal. Can you sort it?
Yes, normally. We check it’s the sealant and not the tray, valve or waste, then strip and reseal the joints.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We will tell you what we are using and why.
Do you have insurance?
Yes. Mr Mastic is fully insured.
How long should I leave it?
Different products cure at different speeds, so follow the cure time we give you when we finish.
Why deal with it now?
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. Around Portvoller, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
What it costs depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.
