Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Never fill a movement joint with mortar or grout
- Keep the room well ventilated
- Check trays and worktops do not move
- Act on a lifting corner right away
If we have found a cause, such as a loose tray or a leaking waste, get it fixed, or the new joint may fail again.
Movement joints that have split let water into the structure, and the longer it’s left, the more the joint edges break down. Resealing while the edges are sound is simpler.

The process
Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a typical bath or shower, longer where several layers have been applied. For a place like Charlestown, 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.
- 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.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Mention if the joints have been sealed before
- Mention any tricky access

Remedial sealant in Charlestown: local notes
Charlestown is close to the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, and sealant and grout that work that hard wear out sooner. Scottish Water supplies are generally soft, so limescale is less of a problem than in hard-water areas. But mould still grows into sealant and grout in a room that does not dry out.
Managing a site like Inverness High School? Then we reseal washrooms and kitchens in schools and businesses as well as homes. Letting a property close to Inverness station? Then failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

Why act early in Charlestown
Hidden water does the most damage: soaked floorboards, ceiling stains below and blown plaster. By comparison, sorting the joint is quick. In a place like Charlestown, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Questions from Charlestown
Can you do remedial sealant in Charlestown?
Yes, Charlestown is within the area we cover. We work across all of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
I let a flat near Inverness station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can send an email to info@mrmastic.co.uk with the details for a clear quote.
Do the sealants smell?
Possibly a little. It fades as the sealant cures, and ventilation helps.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done and we’ll quote it together.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.
Someone sealed over the old bead. Can you fix it?
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.
Should I try DIY first?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Can I choose the sealant colour?
We’ll suggest a colour to suit the surroundings, from white and clear to greys and other shades. The choice depends on the product the joint needs.
Landlords, agents and businesses in Charlestown
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Letting agents often deal with us directly. Tell us the address, the job and how access works.
How we quote for remedial sealant
You’ll get a clear quote before work begins. It’s based on:
- Whether there’s mould to deal with
- Whether the work is at height
- How many areas need sealing
- The number and length of the joints
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Asking for a quote
When you call or email, these details help:
- Access, such as stairs, a lift or height
- Pictures of the joints, sent by email
- What the problem is, such as mould, gaps, leaks or cracking
- Any previous sealing or DIY work
It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll explain how we’d tackle it. Whenever you are ready, drop us a line at info@mrmastic.co.uk.
What sealant work can’t fix
New sealant cannot fix everything, and we’ll tell you before any work starts. Sealant will not put right:
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- Cracks in the fitting rather than the joint
- A leaking trap, valve or supply pipe
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly.
Joints and surfaces we work on
- Mouldy bath & shower sealant
- Expansion joints
- Leaking tray & enclosure joints
- Failed movement joints
- Botched or over-sealed joints
- Shrunken worktop sealant
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
