DIY sealant or a professional job?
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.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Remedial sealant for homes and businesses in St Madoes
Decorators’ caulk in a shower, bathroom silicone on a window, a rigid filler in a movement joint will not last, however tidy it looks. Out it comes, and in goes a sealant suited to the job. Common call-outs are for dark patches showing through the sealant and leaks that keep coming back after resealing, across shrunken worktop sealant, botched or over-sealed joints and mouldy bath & shower sealant.
A bathroom in a place like St Madoes gets the same daily wear as one in a city flat. Generally soft Scottish water means less limescale, but steam still lets mould into sealant and grout.
The work is covered for a year after we finish. If there’s a problem with it, please send an email to info@mrmastic.co.uk.

For landlords and businesses
We also work for property managers and facilities teams in St Madoes and across Perth and Kinross. Several sites can go on one quote, and we are fully insured.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
Honest limits
A few problems are outside what sealant work can do:
- Cracks in the fitting rather than the joint
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- Water damage behind tiles that needs a tiler
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we will tell you honestly.
What we seal
- Mouldy bath & shower sealant
- Botched or over-sealed joints
- Shrunken worktop sealant
- Failed movement joints
- Expansion joints
- Leaking tray & enclosure joints
Why deal with it now?
Leaks that are left keep doing damage out of sight: wet floors, stained ceilings and swollen worktops. By comparison, sorting the joint is quick. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Combining jobs into one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. We will send you a clear quote for the lot.

St Madoes: your questions answered
Is remedial sealant in St Madoes guaranteed?
Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Is St Madoes in your area for remedial sealant?
Yes, St Madoes is within the area we cover. We work across all of Scotland. You can email us at info@mrmastic.co.uk and tell us what needs doing, and we’ll give you a clear price.
Will the old sealant be removed?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Will there be a smell?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
Can you remove old sealant without damaging the bath?
Yes. Careful removal is most of a remedial job, particularly on softer surfaces like acrylic.
Do you offer different sealant colours?
We help you choose a colour that suits. The choice depends on the product the joint needs.
Do you do commercial work?
Yes. We have worked for hotels, offices and other businesses and we’re fully insured.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Do you need remedial sealant in St Madoes?
Products get mixed up: acrylic caulk in a wet area, a general-purpose sealant on a moving joint, or an acetoxy silicone on natural stone or some metals. None of them last.
Look out for these signs:
- Caulk or the wrong sealant used in a wet area
- A second bead peeling off the first
- Sealant that came away because the surface wasn’t prepared
- Kitchen joints letting water behind the worktop
If you live in an older home near St Madoes Parish Church, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.
What to look for in a quote
- How long to leave it before use
- Whether they seal over old material or remove it
- What preparation is included
- What happens if the job turns out different
How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Don’t wait for a small gap to become a leak
- Look for stains below bathrooms now and then
- Use a soft cloth, not a scourer, on silicone
- Keep movement joints clear of mortar and paint
Clean gently: a mild cleaner and a soft cloth, with no blades or scourers.
A split movement joint lets rain into walls and floors, and the longer it’s left, the more the joint edges break down. A joint with sound edges is far easier to reseal.
How the visit works
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours, depending on how many layers have to come out and we leave things clean and tidy. Somewhere like St Madoes 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.
- First we find out how and where the joint has failed.
- Every layer of old sealant is cut and cleaned out.
- Next, any mould is treated and the joint dried.
- We use the right backing and sealant for any joint that moves.
- We tool the joint and tell you about anything else that needs attention.
Getting ready for the visit
- Mention if the joints have been sealed before
- Clear items away from the joints we’re working on
- Mention any sign-in or site rules at work premises

Remedial sealant in St Madoes: local notes
St Madoes 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. Private landlords in Scotland must be registered and meet the Repairing Standard, which includes keeping fixtures and fittings in reasonable repair. Tired, leaking sealant is worth putting right before a new tenant moves in.
Around St Madoes, as everywhere, remedial sealant is only as good as the preparation behind it.
