Remedial sealant in Shawbost, done properly
Water on the floor does not always mean failed silicone. A cracked tray, a failed shower valve or a leaking waste can look just the same. When the fault is elsewhere, we say so instead of resealing for the sake of it. We work on failed movement joints, expansion joints and leaking tray & enclosure joints, and people most often call us about a second bead peeling off the first and products that weren’t meant for the joint.
In and around a place like Shawbost, homes range from older stone-built properties to newer houses. Older buildings can move a little, and that shows first in cracked grout and split sealant.
Every job is covered by a one-year guarantee.

What we do, step by step
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take a few hours for most joints, depending on how much old sealant has to come out. In smaller Scottish places, parking is generally less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- First we work out whether the problem is the sealant, movement or a leak.
- Each layer is cut out and the residue cleaned off.
- Mould is treated and the joint dried.
- We reseal with a product suited to the joint, backed where needed.
- The joint is tooled and you are told about anything else we found.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any parking rules near the property
- For business premises, tell us about site rules or sign-in

Different surfaces, different methods
Over-sealed & botched joints
Botched joints sometimes have damaged edges from earlier scraping. We work carefully to avoid adding to it, and point out any existing damage.
Mouldy bath & shower sealant
Where mould keeps coming back, ventilation is normally part of the cause. Along with resealing, we will mention if the room needs better ventilation.
Remedial sealant around Shawbost
Shawbost is close to the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, and sealant and grout that work that hard wear out sooner. Scotland’s water is generally soft, so sealant and grout see less limescale than in much of England. But mould still grows into sealant and grout in a room that doesn’t dry out.
For jobs in and around Shawbost, choosing the right material for each joint is as important as a tidy finish.

Your questions about remedial sealant in Shawbost
What guarantee comes with remedial sealant in Shawbost?
All our work, in Shawbost and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Do you cover Shawbost for remedial sealant?
Yes. We work across all of Scotland, and Shawbost is part of that. You can send an email to info@mrmastic.co.uk and tell us what needs doing.
Can you strip sealant from an acrylic tray safely?
Yes. We cut and lift the old sealant with tools suited to the surface, then clean off the residue. Any existing damage is pointed out before we start.
Is it worth trying it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.
My shower still leaks after a reseal. Can you sort it?
Yes. We will take all the sealant out, look for why it failed and reseal it properly.
Can you take off two layers of silicone?
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.
Where are you based?
We’re a Crawley-based firm. Our area covers South East England, London and Scotland.
Do you need remedial sealant in Shawbost?
Sealant needs a clean, dry surface with no grease on it. Soap film, dust, damp or old residue stop it gripping, and the joint starts to come away early.
Keep an eye out for any of the following:
- Products that weren’t meant for the joint
- Black mould underneath the bead
- Smears and lumps from a botched reseal
- Beads that never stuck properly
In and around Shawbost, as anywhere, good remedial sealant starts with a clean, dry, properly prepared joint.

Why it’s worth doing now in Shawbost
DIY removal often leaves scratches and a film of residue, and the residue left behind stops the next bead bonding. Careful stripping is where most of our time goes. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and give you a clear price before we start.
Why book with us
- You choose the colour before work begins
- A 12-month guarantee on all work
- Colour picked to suit the job
- White, clear, grey or coloured to suit, where the product allows

Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Check trays and worktops do not move
- Keep the room well ventilated
- Act on a lifting corner right away
- Use a soft cloth, not a scourer, on silicone
If we have found a cause, such as a loose tray or a leaking waste, get it fixed, because the new sealant cannot hold back a problem underneath.
A split movement joint lets rain into walls and floors, and the longer it’s left, the more the joint edges break down. Resealing while the edges are sound is simpler.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
