Problem with your baths, showers and worktops in Cowglen? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.

About our bathroom resealing in Cowglen
A reseal only lasts if the joint is properly prepared. The old sealant is removed to the last smear, then the joint is cleaned, degreased and treated for mould. Only once it’s dry does the new bead go on. We work on sinks & splashbacks, baths and wet rooms, and common reasons people get in touch are two layers of silicone, both failing and damp behind the bath or under the tray.
From stone-built tenements to new flats and suburban houses, Cowglen is in a city with every kind of home. Generally soft Scottish water means less limescale, but steam and poor ventilation still let mould into the sealant and grout.
All of our work is guaranteed for twelve months, in Cowglen and everywhere else we cover.

Cowglen: your questions answered
Can a failed shower seal in a tenement flat in Cowglen leak into the flat below?
It can. Tenement floors are usually timber, and water from a failed seal can find its way down to the flat below, and then the repair involves your neighbours too. Replacing tired sealant early is the simplest way to avoid that.
I let a flat near Kennishead station. Can you help?
Yes. We work for landlords and agents as well as homeowners, and several properties can be quoted together. You can email us at info@mrmastic.co.uk with the details for a clear quote.
Are you insured?
Yes. We’re fully insured, with over 20 years’ experience in sealant work.
How long does it take to reseal a bath or shower?
One bath or shower is around two hours’ work, old sealant removal included. A full bathroom and kitchen can take most of a day.
Do you come to Cowglen?
We do. Cowglen is part of the area we cover.
What does bathroom resealing cost?
Every job is different, so each one gets its own quote. To get one, send an email to info@mrmastic.co.uk with a short description of the job.
Is there any odour?
Some sealants have a smell while they cure. Opening a window helps.
My sealant has gone black. Can you sort it?
Yes. Once mould has grown into the silicone, it usually can’t be cleaned out for good, so the bead comes out, the joint is treated and new anti-fungal silicone goes in.
DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Landlord and commercial work in Cowglen
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
We work for letting agents and landlords as well as homeowners. Sealant work between tenants keeps a property looking cared for.
Bathrooms and kitchens in Cowglen
Sandstone tenements are a big part of Glasgow’s housing, where most bathrooms sit above another flat. Scotland’s water is generally soft, so sealant and grout see less limescale than in much of England. But mould still grows into sealant and grout in a room that doesn’t dry out.
For landlords with property near Kennishead station, mouldy sealant is one of the first things a new tenant notices, so it’s worth renewing between lets.

- Tiles that have come away from the wall
- A leaking waste, trap or valve
- Cracked or missing grout between tiles (that’s regrouting)

Where we work in Cowglen
- Shower trays & enclosures
- Sinks & splashbacks
- Kitchen worktops & upstands
- Baths
- Wet rooms
- Basins & vanity units
Surface by surface
Wet rooms
A wet room floor and its walls can move independently, so the internal corners need silicone rather than grout. Where grout in a corner has cracked, we can replace it with sealant.
Basins & vanity units
A vanity top has a joint along the wall and sometimes at the sides. Water that gets behind can damage the unit, so a neat, continuous bead matters.
Common problems we fix in Cowglen
Black mould is behind a lot of resealing. Bathrooms without good ventilation give mould all the damp it needs, and mould that has grown into the silicone usually will not clean off.
If you can see any of these, it’s time to have the joints looked at:
- Sealant that has split, shrunk or peeled away
- Splits where the tray meets the wall
- Leaks into the floor or ceiling below
- Water escaping at the shower enclosure
If you look after a building such as St. Paul's High School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

What happens on the day
Every visit runs the same way: we look at the joints together, protect the area around them, do the work and tidy away. It normally takes around two hours for one bath or shower, longer for a whole bathroom. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. In Cowglen, it helps to know the floor, the door entry arrangements and the nearest parking.
- We cover the area around the joints we’re working on.
- Old sealant is sliced away and the residue removed.
- We treat any mould and let the joint dry properly.
- Baths are filled first, then anti-fungal sanitary silicone is applied in a colour to suit.
- The joint is finished neatly and we explain when it can get wet.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Where the joints are inside, avoid wetting them before we arrive
- Move anything stored near the joints

Leave it or put it right?
The difference in a professional reseal is mostly what you do not see: cutting out every trace of the old bead, cleaning, treating mould and letting the joint dry. Without that preparation, the new bead won’t last. Wind-driven rain gets into any failed joint on the outside of a city building, and in Cowglen, damp can spread through stone and plaster before anyone sees it.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.
What you get with us
- One-year guarantee on every job
- An ARBOMaster approved applicator
- Anti-fungal sanitary silicone in wet areas
- Domestic, commercial and hotel work
