What affects the cost of remedial sealant
There’s no set price list, because jobs vary so much. The quote depends on:
- How much there is to do
- The product the joint needs
- How easy the joints are to reach
- Whether old sealant or filler has to be cut out
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.

About our remedial sealant in Rhu
Water on the floor doesn’t always mean failed silicone. Cracked trays, leaking wastes and faulty valves often look like a sealant problem. When the fault is elsewhere, we say so instead of resealing for the sake of it. If you are dealing with sealant that came away because the surface wasn’t prepared and mould trapped under a layer of silicone, we can put it right.
For a place like Rhu, the job is the same as anywhere: old material out, joints cleaned and dried, and a fresh, even finish. We just plan the journey and access beforehand.
The work is covered for a year after we finish. If there’s a problem with it, please drop us a line at info@mrmastic.co.uk.

Looking after it afterwards
So the new joints stay in good condition:
- Always have old sealant cut out, not covered
- Find out why the sealant failed first
- Don’t wait for a small gap to become a leak
- Keep an eye on the ceiling below the bathroom
Leave the new joint to cure fully before it gets wet or moves: follow the cure time we give you.
Warning signs: sealant lifting at the ends, a second bead visible on top of the first, black mould under the silicone, or stains below a bathroom. Any of them means it’s time for remedial work.

Remedial sealant around Rhu
Rhu 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, 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.
Homes close to Rhu Parish Church include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them. For landlords with property near Helensburgh Upper station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. Managing a site like Lomond School? Then washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes.

How it works
We keep the work tidy and contained to the area we’re working on, so you can get on with your day. The job usually takes a few hours for a typical bath or shower, longer where several layers have been applied, and we explain the cure time before we leave. In smaller Scottish places, parking is normally less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We protect the surfaces around the joint.
- The botched or failed sealant is cut away completely.
- We clean and degrease the joint and look for signs of movement or water.
- New sealant goes in once the joint is dry, and is tooled smooth.
- You get the cure time and our view on why the joint failed.
Before we arrive
- Let us know about parking restrictions
- Tell us about any water getting in
- Mention any tricky access

Related advice
Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What happens if it’s left?
It’s easy to scratch acrylic, enamel or an uPVC frame cutting out old sealant, and any film left behind stops new sealant sticking. Careful stripping is where most of our time goes. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, email us at info@mrmastic.co.uk and we’ll give you an honest view and a quote.

Yes. Hotel and guest-house work is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
Will you come out to Rhu?

Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.
Where is Mr Mastic based?

How long does the work take?
Allow a few hours, depending on how many layers have to come out. We’ll give you a timescale when we quote.
Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Do you guarantee remedial jobs?
Yes, for 12 months. Where we have flagged another fault, it needs fixing for the joint to last.
