Remedial sealant in Smithstone
A movement joint stops working when its sealant splits or sets hard. We cut out the failed sealant and set the depth with backing, before resealing with a flexible product suited to the movement. We work on botched or over-sealed joints, leaking tray & enclosure joints and mouldy bath & shower sealant, and the jobs we see most are sealant applied over old sealant that has lifted and floor or wall movement joints that have failed.
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.
The work is covered for a year after we finish. If there’s a problem with it, please email us at info@mrmastic.co.uk.

Asking for a quote
To make quoting easier, please include:
- What the problem is, such as mould, gaps, leaks or cracking

Different surfaces, different methods
Movement & expansion joints
Bonding on three sides is a common reason movement joints tear. Backing rod or bond-breaker tape prevents it, letting the sealant flex between the two faces.
Worktops & kitchens
Shrunken worktop sealant leaves a gap that lets water into the back edge. We strip it, degrease the joint and reseal in a colour to suit.
Smithstone: your questions answered
Will you come out to Smithstone?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you cover Smithstone for remedial sealant?
Yes. Our work covers the whole of Scotland, and Smithstone is part of that. Just email us at info@mrmastic.co.uk with a few details of the job.
How long should I leave it?
Cure times vary by product and the temperature. Before we leave, we’ll tell you the cure time.
Can tenants book the work?
Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.
Where do you work from?
Mr Mastic is based in Crawley. We cover Smithstone and the rest of North Lanarkshire.
My shower still leaks after a reseal. Can you sort it?
Yes. We’ll take all the sealant out, look for why it failed and reseal it properly.
Do you have insurance?
Yes. We are fully insured.
Can I do it myself?
You can, for simple jobs. 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.
What we are called out for in Smithstone
How a joint is built matters as much as the product. Sealant packed too deep, or stuck to the back of the joint as well as the sides, can’t stretch, so it tears when the joint moves. Backing rod or bond-breaker tape prevents it.
People usually contact us when they notice something like this:
- Caulk or the wrong sealant used in a wet area
- Sealant that came away because the surface wasn’t prepared
- Floor or wall movement joints that have failed
- Repeat leaks from the same joint
For site and facilities teams at buildings such as Our Lady's High, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

Leave it or put it right?
Stripping out botched sealant adds time to a reseal, but rarely a lot: the work takes a few hours for a typical bath or shower, longer where several layers have been applied. It’s far less disruption than resealing the same joint again and again. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.

Advice
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Do not point over movement joints
- Get the cause of a repeat leak found before resealing
- Look for stains below bathrooms now and then
- Run the fan after every shower
Where we’ve pointed out another fault, have it put right, because the new sealant cannot hold back a problem underneath.
Warning signs: peeling layers, mould showing through the bead, leaks after showering or cracks in a movement joint. Any of them means it’s time for remedial work.
Bathrooms and kitchens in Smithstone
Private landlords in Scotland must be registered and meet the Repairing Standard, which includes keeping fixtures and fittings in reasonable repair. Failed sealant around a bath or shower is worth sorting between tenancies. 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.
Rented homes near Croy station change hands often, and a joint that keeps failing is best fixed properly while the property is empty.
