DIY versus a professional finish
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Movement from fittings that aren’t supported
- A leaking trap, valve or supply pipe
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
If you are not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer before you book.
Joints and surfaces we work on
- Failed movement joints
- Botched or over-sealed joints
- Shrunken worktop sealant
- Expansion joints
- Leaking tray & enclosure joints
- Mouldy bath & shower sealant
Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Keep bleach and abrasives off the bead
- Report a tray that rocks or a worktop that lifts
- Keep the room well ventilated
- Check ceilings under showers for marks
Keep the room ventilated: run the fan during and after showers, or open a window.
Movement joints that have split let water into the structure, and left long enough, the edges of the joint can crumble. Resealing while the edges are sound is simpler.
Remedial sealant around Isle of Whithorn
Isle of Whithorn 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. In Scotland, private landlords have to 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.
In the older streets around Isle Parish Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them. In and around Isle of Whithorn, as anywhere, good remedial sealant starts with a clean, dry, properly prepared joint.

What the job involves on each surface
Windows & doors
A frame that keeps leaking may not be the mastic. If the frame joint isn’t the cause, we’ll say so.
Mouldy bath & shower sealant
Mould can sit behind the silicone, not just in it. Once it’s all removed, the joint is treated.

Isle of Whithorn: your questions answered
Is Isle of Whithorn in your area for remedial sealant?
Yes, Isle of Whithorn is within the area we cover. We work across all of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear price.
Do you cover smaller places like Isle of Whithorn?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Can you remove old sealant without damaging the bath?
Yes, with care. The old bead is cut and lifted with tools that suit the surface, and the residue is cleaned away. We point out any damage that’s already there.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
My shower still leaks after a reseal. Can you sort it?
Yes. We’ll take all the sealant out, look for why it failed and reseal it properly.
What if the leak is not the sealant?
That is why we look for the cause first. If we find the leak is elsewhere, we tell you before going further.
Will there be a smell?
Some sealants have a smell while they cure, but it fades. Ventilation helps.
Can you remove sealant that’s been put over old sealant?
Yes. It’s slower than a standard reseal, because every layer has to come out cleanly, but it’s the only way the new joint will last.
What happens if it’s left?
Another bead over the top will not fix a failed joint. It does not grip the old layer, leaving the leak in place and one more layer to cut out later. 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.
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first.
