What affects the cost of bathroom resealing
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Any working-time requirements on site
- Which sealant suits the joint
- How many rooms, windows or areas are involved
- The old material and how stubborn it is

Bathroom resealing in St Marys
A shower joint gets soaked every day. Trays, enclosures, screen profiles and wet room floors all need a flexible, waterproof seal. Each gets a bead of anti-fungal sanitary silicone, tooled smooth so water runs off instead of sitting in a ridge. If you’re dealing with splits where the tray meets the wall and water getting behind the bath panel, we can help.
Tenement flats are common in all four of Scotland’s big cities, alongside houses and newer flats. In a tenement, most bathrooms sit above someone else’s ceiling, so failed sealant around a bath or shower can soon become a neighbour’s problem.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

What happens on the day
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and clear up. It generally takes two to three hours for a typical bath, depending on how much old sealant there is. Parking in city streets around St Marys can be tight or controlled, so it helps to know about permits or nearby bays. If you’re in a flat, let us know how we get in at the street door.
- We look at every joint first and check for movement or leaks.
- The old silicone is cut out completely, along with the film it leaves on the tiles.
- The joint is cleaned, degreased and treated for mould.
- When the joint is dry, and a bath has been filled with water, the new silicone goes on.
- We tool the bead to a neat finish and give you the cure time, generally around 24 hours.
Before we arrive
- Try not to wet indoor joints just before the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Keep children and pets away from the work area

What the job involves on each surface
Basins & vanity units
The back of a basin gets wet every time someone washes. Old sealant there often goes black at the corners, and we treat it exactly as we would a bath.
Shower trays & enclosures
Water often gets past the wall profile of a shower enclosure. We reseal it along with the base of the enclosure, sealing the side the enclosure’s instructions call for.
Do you need bathroom resealing in St Marys?
Mould is the reason many people want their sealant replaced. Bathrooms without good ventilation keep the silicone damp for hours, and once it has grown into the bead, cleaning rarely gets it out.
Common reasons people contact us are:
- A bead that has pulled away from the tiles
- Gaps where the bath or tray has moved
- Leaking joints on a shower screen
- A messy, uneven bead from a previous reseal
For site and facilities teams at buildings such as Lawside Academy, 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.
Questions to ask before booking
- Whether VAT is included
- Who turns up on the day
- How the colour is chosen
- Is the old sealant removed completely?
Bathroom resealing around St Marys
St Marys is close to the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, which wears sealant and grout out faster than in a quiet home. Dundee has plenty of sandstone tenements, where a failed bath or shower seal can reach the flat below.
Letting a property close to Invergowrie station? Then fresh sealant around the bath, shower and sink between tenancies helps a property present well and keeps leaks at bay.

Your questions about bathroom resealing in St Marys
I let a flat near Invergowrie station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear quote.
I’m in a tenement in St Marys. Could worn sealant affect the flat downstairs?
Yes. With flats above and below, a leak from a failed seal rarely stays in one flat. A proper reseal, with all the old sealant cut out, stops it at the source.
How much does bathroom resealing cost in St Marys?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we will talk you through it.
How long does it take to reseal a bath or shower?
Allow two to three hours for a typical bath, depending on how much old sealant there is. You’ll know how long to expect before we start.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done.
Do the sealants smell?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
Do I have to be there?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
My sealant has gone black. Can you sort it?
Yes, we can. The old sealant comes out, the mould is treated, and we reseal with anti-fungal sanitary silicone.
Why deal with it now?
Bleach and mould sprays may lighten black marks for a while, but where mould is inside the silicone it normally comes back. The lasting answer is to remove the bead and start again. In a tenement flat in St Marys, a failed seal is rarely just your problem: a leak can come through the ceiling below, and gaps in shared walls or fire-rated joints matter to every flat.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
What you get with us
- We never seal over old sealant
- Anti-fungal sanitary silicone in wet areas

Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Clean with a mild bathroom cleaner and a soft cloth
- Keep scourers and sharp tools away from the bead
- Do not leave water standing on kitchen joints
- Wipe the sealant dry after showering
Do not stand bottles along the bead, as they hold water against it. Squeegeeing the walls and tray after use helps the joint dry.
Each shower pushes a little more water through a failed joint. Left alone, it soaks into the floor, the wall behind the tiles or the ceiling below. Early resealing closes the gap before damage is done.
