Remedial sealant for homes and businesses in Strontian
Movement and expansion joints fail when the sealant can’t stretch. We cut out the failed sealant and set the depth with backing, then a flexible sealant matched to the movement goes in. If you are dealing with dark patches showing through the sealant and repeat leaks from the same joint, we can help, whatever the surface.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses. Where a building moves, cracked grout and split sealant are usually the first signs.
Our work is backed for twelve months.

Remedial sealant around Strontian
Strontian is within about 1 mile of the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, which wears sealant and grout out faster than in a quiet home. 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.
Around Strontian, as everywhere, remedial sealant is only as good as the preparation behind it.
Strontian (Gaelic: Sron an t-Sithein) is in Highland. Across the PH36 area, we can carry out remedial sealant at your property. Our Highland coverage runs to 253 places, and Strontian is one of them. Our Glasgow page covers work nearby (76 miles or so).

Common problems we fix in Strontian
Silicone only bonds to surfaces that are clean and dry. Residue, moisture or dust left in the joint weaken the bond, so it starts lifting sooner than it should.
These are the problems we’re asked about most:
- Products that weren’t meant for the joint
- Mould trapped under a layer of silicone
- Torn expansion joints
- Worktop sealant that has shrunk and split
Homes close to Strontian Church include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them.
What your quote should include
- What insurance they hold
- What happens if the job turns out different
- Is the old sealant removed completely?
- How long the guarantee is
Should I try it myself first?
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.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.

FAQs for Strontian
Is remedial sealant in Strontian guaranteed?
All our work, in Strontian and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Is Strontian in your area for remedial sealant?
Yes, Strontian is within the area we cover. We work across all of Scotland. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Can you remove old sealant without damaging the bath?
Yes. We take our time over removal, particularly on softer surfaces like acrylic.
I’m a tenant. Can you help?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
Do the sealants smell?
There can be a smell while the sealant cures. Opening a window helps.

How the job changes by surface
Mouldy bath & shower sealant
Repeat mould usually points to a damp, poorly aired room. Along with resealing, we will mention if the room needs better ventilation.
Windows & doors
Wrong-coloured or messy mastic can be replaced for appearance too, in a colour that suits the frame.
The process
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours for a typical bath or shower, longer where several layers have been applied. For a place like Strontian, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Old beads and residue are removed down to clean surfaces.
- 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.
Before we arrive
- Clear items away from the joints we are working on
- For business premises, tell us about site rules or sign-in
- Tell us about any water getting in
Getting a quote
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. When it suits you, send an email to info@mrmastic.co.uk.
Advice
Why deal with it now?
A failed seal rarely means a new bathroom. When the fittings are sound, stripping and resealing the joints is often enough. Where something else has failed, you’ll hear it from us. In an older home around Strontian, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and give you a clear price before we start.
