About our remedial sealant in Dunkeld
Water on the floor doesn’t always mean failed silicone. A cracked tray, a failed shower valve or a leaking waste can look just the same. If that’s what we find, we will tell you rather than reseal something that won’t fix it. If you have movement joints that have split or pulled away and decorators’ caulk around a bath or shower, we can put it right, whatever the surface.
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 one-year guarantee, so you’re not left on your own once the job is done.

Do you need remedial sealant in Dunkeld?
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.
Keep an eye out for these signs:
- Gaps opening along the back of the worktop
- Over-sealed joints coming away
- Sealant that came away because the surface wasn’t prepared
- Mould trapped under a layer of silicone
In and around Dunkeld, as anywhere, good remedial sealant starts with a clean, dry, properly prepared joint.

Dunkeld questions
Do you work for hotels and guest houses in Dunkeld?
Yes, hotels and guest houses are among the places we work. A room-by-room programme keeps most rooms in use while the work goes on.
Can you help a landlord with a rental near Dunkeld & Birnam station?
Yes, rental work is part of what we do. You can email us at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before work begins.
Can I choose the sealant colour?
Usually, yes. White, clear and grey are common, and other colours are available for many products, and we agree the colour with you before any work starts.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status and we are fully insured too.
Where are you based?
Our base is Crawley. Our area covers South East England, London and Scotland.
My shower still leaks after a reseal. Can you sort it?
Yes. Repeat leaks generally come from over-sealing, movement or water getting in elsewhere, and we deal with the cause first.
Do the sealants smell?
Possibly a little. It fades as the sealant cures, and ventilation helps.
Are you insured?
Yes. Mr Mastic is fully insured.
Leave it or put it right?
Spraying mould remover on a sealed-over joint does not reach what’s underneath. Removal is the only way to get at it, so the joint can be treated and resealed. In an older home around Dunkeld, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before work begins, so you know where you stand.
Why us?
- You choose the colour before work begins
- 12-month guarantee on every job
- More than 20 years in sealant work
- Fully insured

What sealant work can’t fix
We’ll always be straight with you, so here’s what new sealant will not do:
- Cracks in the fitting rather than the joint
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- Movement from fittings that aren’t supported
Not sure which it is? You can email us at info@mrmastic.co.uk and we will tell you honestly before booking.
Surfaces we seal
- Mouldy bath & shower sealant
- Expansion joints
- Failed movement joints
- Shrunken worktop sealant
- Botched or over-sealed joints
- Leaking tray & enclosure joints
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Don’t add new sealant on top of old
- Act on a lifting corner right away
- Keep bleach and abrasives off the bead
- Run the fan after every shower
Keep an eye on the joint at first, especially if movement was the problem. Should anything change, send an email to info@mrmastic.co.uk.
Leaks through failed sealant grow over time. Every shower or downpour sends more water through, into floors, walls or ceilings. Sorting it early limits the damage.
What affects the quote in Dunkeld
There’s no set price list, because no two jobs are the same. What we look at:
- Access and height
- Working hours on commercial sites
- How many areas need sealing
- Any mould that needs treating
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What we need to know
There’s no need for technical detail. Just tell us:
- The problem you’ve noticed
- The rough size of the job
- Access, such as stairs, a lift or height
- Any previous sealing or DIY work
For a quick quote, get us on the phone, or send an email if you’d rather. Describe what needs sealing and we will talk you through the work.
What we do, step by step
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 a typical bath or shower, longer where several layers have been applied. Outdoor work around Dunkeld depends on the weather, as sealant needs a dry surface, 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.
- Old beads and residue are removed down to clean surfaces.
- Mould is treated and the joint dried.
- We reseal with a product suited to the joint, backed where needed.
- We finish neatly and point out anything that needs another trade.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- On commercial sites, let us know about site rules
- Let us know about stairs, lifts or work at height

Advice
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
