Remedial sealant in Walls from a team with over 20 years’ experience. Rated 4.9 on Google from 180+ five-star reviews.

- Kitchen joints letting water behind the worktop
What we are called out for in Walls
Movement tears sealant that isn’t designed for it. Flexing baths, rocking trays and building movement joints will split a rigid or thin bead.
These are the problems we are asked about most:
- Black mould underneath the bead
- Sealant applied over old sealant that has lifted
- Products that weren’t meant for the joint
- Kitchen joints letting water behind the worktop
In and around Walls, as anywhere, good remedial sealant starts with a clean, dry, properly prepared joint.

Remedial sealant in Walls, done properly
If a joint fails again and again, something is causing it. A tray that moves, a worktop that is not fixed, the wrong sealant or water getting in elsewhere will beat any new bead. Finding that cause comes before any new sealant. If you are dealing with a second bead peeling off the first and products that weren’t meant for the joint, we can put it right, whatever the surface.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses. Older buildings can move a little, and that shows first in cracked grout and split sealant.
There’s a 12-month guarantee on every job, whatever its size.

How we quote for remedial sealant
Every job gets its own quote. These are the things that affect it:
- The number and length of the joints
- Whether old sealant or filler has to be cut out
- Whether there’s mould to deal with
- Working hours on commercial sites
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we’ll go through it with you.
Helping us quote
Photos help, but a description is a good start. Please mention:
- The problem you’ve noticed
- Any access issues, like height or stairs
- How many joints, rooms or windows are involved
- Where the property is
Every job is quoted individually, so start by telling us what you need. Simply drop us a line at info@mrmastic.co.uk and describe the job.
Aftercare tips
Good habits help new joints last longer. A few tips:
- Check ceilings under showers for marks
- Use a soft cloth, not a scourer, on silicone
- Keep movement joints clear of mortar and paint
- 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.
Mould trapped under over-sealed joints spreads unseen. When it finally shows, the whole bead needs to come out.
Work for landlords, hotels and businesses
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we are fully insured.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
How it works
Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it normally takes a few hours for a typical bath or shower, longer where several layers have been applied. For a place like Walls, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- First we work out whether the problem is the sealant, movement or a leak.
- Each layer is cut out and the residue cleaned off.
- We treat any mould and dry the joint thoroughly.
- We reseal with a product suited to the joint, backed where needed.
- We finish neatly and point out anything that needs another trade.
Before we arrive
- Try not to wet indoor joints just before the visit
- Tell us about any water getting in
- Tell us about access, such as stairs, a lift or high-level joints

Different surfaces, different methods
Worktops & kitchens
Kitchen joints hold grease and residue, so we spend extra time cleaning.
Mouldy bath & shower sealant
Where mould keeps coming back, ventilation is usually part of the cause. Along with resealing, we’ll mention if the room needs better ventilation.
Common questions in Walls
Do you cover Walls for remedial sealant?
Yes. Our work covers the whole of Scotland, and Walls is part of that. You can send an email to info@mrmastic.co.uk and let us know what needs doing.
Will you come out to Walls?
Yes, Walls is covered. We work across all of Scotland, islands included, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
What if resealing won’t fix my leak?
We check for that before we reseal. If we find the leak is elsewhere, we tell you before going further.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Are you insured?
Yes. We’re fully insured.
How much does remedial sealant cost in Walls?
It depends on the job, so we quote each one individually. For a quick quote, send an email to info@mrmastic.co.uk with a short description of the job.
Can failed expansion joints be resealed?
Yes. We cut out the failed sealant, fit backing and reseal with a flexible product.
My shower still leaks after a reseal. Can you sort it?
Yes. There’s generally a reason: sealant over sealant, movement or another leak, so we find that first.
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
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.
Remedial sealant around Walls
Walls is within about 1 mile of 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. Mould is another matter: a bathroom that stays damp still turns sealant and grout black.
Whether the job is in Walls itself or nearby, the right material for each joint matters as much as a neat finish.
