About our remedial sealant in Strathmartine
A joint that keeps failing generally has a reason. Movement, the wrong product or a leak from somewhere else will beat any new bead. Finding that cause comes before any new sealant. We work on failed movement joints, mouldy bath & shower sealant and leaking tray & enclosure joints, and common reasons people get in touch are torn expansion joints and kitchen joints letting water behind the worktop.
In and around a place like Strathmartine, homes range from older stone-built properties to newer houses. Where a building moves, cracked grout and split sealant are usually the first signs.
Big or small, you get the same 12-month guarantee in Strathmartine and across Dundee.

What remedial sealant looks like in Strathmartine
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. Dundee has plenty of sandstone tenements, where a failed bath or shower seal can reach the flat below.
For landlords with property near Dundee station, botched sealant from a previous quick fix is easier to strip out between tenants.

Common questions in Strathmartine
Will you come out to Strathmartine?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for landlords with property near Dundee station?
Yes, we work for letting agents and landlords. You can drop us a line at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before work begins.
Do you offer different sealant colours?
We help you choose a colour that suits, from white and clear to greys and other shades. The choice depends on the product the joint needs.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Can I add another job to the visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Does remedial work come with a guarantee?
Yes. Every job comes with our one-year guarantee.
Is it messy?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We cut it out and start again.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
When to call us in Strathmartine
Joints that move need sealant that can stretch. A bath that flexes, a tray that rocks or a building joint that opens and closes split any bead that’s too stiff or too thin.
Any of these means the joints need attention:
- Repeat leaks from the same joint
- Sealant that came away because the surface wasn’t prepared
- Gaps opening along the back of the worktop
- Wide, uneven beads that look worse than the old ones
For site and facilities teams at buildings such as Baldragon Academy, we reseal washrooms and kitchens in schools and businesses as well as homes.

Why deal with it now?
Stripping out botched sealant adds time to a reseal, but not by much: the work takes a few hours for most joints, depending on how much old sealant has to come out. It’s far less disruption than resealing the same joint again and again. In a place like Strathmartine, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first.
Why book with us
- Full insurance on every job
- Arbo and Everbuild products

What happens on the day
You do not need to clear the whole room or building, just the space around the work. We protect the rest, and the job takes a few hours for a typical bath or shower, longer where several layers have been applied for a typical job. Outside jobs in Strathmartine need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- 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 parking rules near the property
- Clear the area around the work
- On commercial sites, let us know about site rules

How we quote for remedial sealant
There’s no set price list, because jobs vary so much. What we look at:
- How many areas need sealing
- Working hours on commercial sites
- How easy the joints are to reach
- Which sealant suits the joint
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
What to tell us for a quote
Photos by email are helpful but not essential. Please mention:
- The rough size of the job
- The address or postcode of the job
- Photos by email, if that’s easy
- The problem you’ve noticed
For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we’ll explain what’s involved and give you a clear price.
Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Report a tray that rocks or a worktop that lifts
- Deal with small splits early
- Run the fan after every shower
- Get the cause of a repeat leak found before resealing
Give the new sealant its full cure time: usually around 24 hours, or as long as we advise.
Warning signs: peeling layers, mould showing through the bead, leaks after showering or cracks in a movement joint. Each one is worth getting looked at.
