DIY sealant or a professional job?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Remedial sealant in Stobswell, done properly
In Stobswell, as anywhere, remedial jobs tend to look alike: over-sealed joints, hidden mould, repeat leaks and split movement joints. We strip each one back and start from scratch. We work on expansion joints, leaking tray & enclosure joints and shrunken worktop sealant, and common reasons people get in touch are dark patches showing through the sealant and floor or wall movement joints that have failed.
From stone-built tenements to new flats and suburban houses, Stobswell is in a city with every kind of home. Scottish water is generally soft, so limescale is less of a problem than in hard-water areas, but mould still grows into sealant and grout in a steamy bathroom.
We stand behind the work with a 12-month guarantee, so you are covered after we’ve gone.

What we do, step by step
On the day, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before any work begins. The work generally takes a few hours, depending on how many layers have to come out. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. In Stobswell, it helps to know the floor, the door entry arrangements and the nearest parking.
- We protect the surfaces around the joint.

Mouldy bath & shower sealant
Repeat mould generally points to a damp, poorly aired room. We will reseal and tell you if extraction looks to be the issue.
Over-sealed & botched joints
Every layer has to come out, and silicone residue is cleaned off the tiles too. New sealant needs a fully clean surface.

Scottish Water supplies are generally soft, so limescale is less of a problem than in hard-water areas. Mould is another matter: a bathroom that stays damp still turns sealant and grout black.

FAQs for Stobswell
Do you work for hotels and guest houses in Stobswell?
Yes, we work for hotels as well as homes and businesses. A room-by-room programme keeps most rooms in use while the work goes on.
Can you help a landlord with a rental near Dundee station?
Yes, landlords and agents are among the people we work for. You can email us at info@mrmastic.co.uk with the details for a clear quote.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Can you remove old sealant without damaging the bath?
Yes. Careful removal is most of a remedial job, particularly on softer surfaces like acrylic.
Do you remove the old sealant?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Will it make a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
How much does remedial sealant cost in Stobswell?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.
My shower still leaks after a reseal. Can you sort it?
Yes. There’s usually a reason: sealant over sealant, movement or another leak, and we deal with the cause first.
What sealant work can’t fix
To be straight with you, some problems need a different trade:
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- Cracks in the fitting rather than the joint
- Failed tanking or loose tiles behind the sealant
If you’re not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer before booking.
Joints and surfaces we work on
- Mouldy bath & shower sealant
- Expansion joints
- Botched or over-sealed joints
- Leaking tray & enclosure joints
- Shrunken worktop sealant
- Failed movement joints
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Never seal over old silicone
- Clean sealant with mild products only
- Look for stains below bathrooms now and then
- Get the cause of a repeat leak found before resealing
Leave the new joint to cure fully before it gets wet or moves: follow the cure time we give you.
Movement joints that have split let water into the structure, and left long enough, the edges of the joint can crumble. Resealing while the edges are sound is simpler.
Quotes for remedial sealant in Stobswell
There’s no set price list, because jobs vary so much. The quote depends on:
- The number of rooms or windows
- Mould in or behind the old joints
- How much old sealant there is and how hard it is to remove
- Which sealant suits the joint
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and agree the price before starting.
Asking for a quote
You do not need to know the technical terms. Just tell us:
- How we’d reach the joints
- What’s wrong with the joints now
- How many joints, rooms or windows are involved
- Whether it’s a home or a business
For a quote, send an email to info@mrmastic.co.uk and tell us where the job is and what the problem looks like. You’ll have a clear quote before work begins.
What we are called out for in Stobswell
Some joints fail because water is reaching them from behind. A slow leak behind the tiles soaks the joint from the back, so the silicone goes mouldy or lets go.
People generally contact us after spotting something like this:
- Sealant applied over old sealant that has lifted
- Mould trapped under a layer of silicone
- Thick, messy sealant smeared over tiles
- Floor or wall movement joints that have failed
For an older house near a landmark such as St Patrick's R.C. Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them.
