About our remedial sealant in Largs
Some sealant jobs aren’t a simple reseal, because someone has already had a go. New sealant over old, smeared beads, unsuitable products and hidden mould all need stripping out. We’re often asked to deal with decorators’ caulk around a bath or shower and movement joints that have split or pulled away, on expansion joints, botched or over-sealed joints and leaking tray & enclosure joints.
A bathroom in a place like Largs 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.
A 12-month guarantee comes as standard, so you’re covered after we’ve gone.

Photos by email are helpful but not essential. Try to tell us:

- What’s wrong with the joints now
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.
Largs homes and their sealant
Largs is within about 1 mile of the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, which wears sealant and grout out faster than in a quiet home. Largs has hotels and guest accommodation nearby. Hotel bathrooms are part of our work as well as homes, and can be done room by room.
For landlords with property near Largs station, botched sealant from a previous quick fix is easier to strip out between tenants.

How to look after the new joints
Good habits help new joints last longer. Our tips:
- Run the fan after every shower
- Deal with small splits early
- Never fill a movement joint with mortar or grout
- Clean sealant with mild products only
Keep the room ventilated: run the fan during and after showers, or open a window.
Do not keep resealing the same joint. Have someone find out why, or the next bead will go the same way.
For landlords and businesses
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
How the job changes by surface
Over-sealed & botched joints
Every layer has to come out, and silicone residue is cleaned off the tiles too. Only a clean joint will take a new bead.
Leaking trays & enclosures
If the tray is cracked, or the leak is from the valve or waste, sealant won’t fix it. We’ll tell you what we find.
The process
When we arrive, we look over the joints with you first. We protect the surfaces around the joints before we start. The work normally takes a few hours for a typical bath or shower, longer where several layers have been applied. In smaller Scottish places, parking is generally less of an issue than access and distance. Let us know how to find you and how to reach the joints.
- 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’re told about anything else we found.
Getting ready for the visit
- Tell us about any water getting in
- Mention if the joints have been sealed before
- On commercial sites, let us know about site rules

Advice
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
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.
FAQs for Largs
Do you work for hotels and guest houses in Largs?
Yes, we work for hotels as well as homes and businesses. Rooms can be done a few at a time, so the building stays open.
Do you work for landlords with property near Largs station?
Yes. We work for landlords and letting agents as well as householders, and several properties can be quoted together. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
What does remedial sealant cost?
Size, access and the old material all affect the cost. Ask us for a quote.
How long should I leave it?
That depends on the sealant used, so please follow the time we give you when we finish.
What information do you need?
Let us know what needs doing and where. We’ll ask anything else we need to know.
Can you do several jobs on one visit?
Yes. Several rooms, windows or areas can go on one quote.
Is it messy?
We keep the work tidy. We protect what’s around the joints.
Common problems we fix in Largs
Silicone only bonds to surfaces that are clean and dry. Soap film, dust, damp or old residue stop it gripping, and the joint starts to come away early.
It’s worth asking for a quote if you see:
- Over-sealed joints coming away
- Worktop sealant that has shrunk and split
- Black mould underneath the bead
- Torn expansion joints
Schools such as Largs Academy are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes.
