Different surfaces, different methods
Over-sealed & botched joints
Every layer has to come out, including the smears and film on surrounding tiles. New sealant needs a fully clean surface.
Leaking trays & enclosures
Where the joints are the problem, every bead is stripped and resealed with anti-fungal sanitary silicone, including the screen profile and tray edges.
What we do, step by step
We keep the work tidy and contained to the joints we’re treating, so you can get on with your day. The job usually takes a few hours, depending on how many layers have to come out, and we explain the cure time before we leave. Around Keir Mill, distance and access matter more than parking. Let us know how to find you and how to reach the joints.
- Surrounding tiles, trays and frames are protected first.
- Every layer of failed sealant is stripped out.
- The joint is degreased and checked for movement and leaks.

Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.

Of course. Check with your landlord; we can send the quote to them too.

It depends on the job, so we quote each one individually. To get one, send an email to info@mrmastic.co.uk and tell us what needs doing and where.

Why deal with it now?
Mould under a bead cannot be reached by cleaning. Removal is the only way to get at it, and the joint treated and dried before resealing. In an older home around Keir Mill, damp from a failed joint can get into timber and plaster.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

Bathrooms and kitchens in Keir Mill
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. In Scotland, private landlords have to meet the Repairing Standard, which covers keeping fixtures and fittings in a reasonable state of repair. Failed sealant around a bath or shower is worth sorting between tenancies.
For site and facilities teams at buildings such as Wallace Hall Academy, we reseal washrooms and kitchens in schools and businesses as well as homes.

When it isn’t the sealant
We will not take on work that won’t last, so these are the limits:
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- Sealant in an older building that needs testing for asbestos first
- A tray or bath that is cracked
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly before booking.
Surfaces we seal
- Leaking tray & enclosure joints
- Shrunken worktop sealant
- Mouldy bath & shower sealant
- Failed movement joints
- Botched or over-sealed joints
- Expansion joints
How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Keep the room well ventilated
- Check trays and worktops don’t move
- Do not point over movement joints
- Deal with small splits early
Watch the joint over the first few weeks, especially if movement was the problem. If anything changes, just send an email to info@mrmastic.co.uk.
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.
What we are called out for in Keir Mill
Joint depth matters. Sealant packed too deep, or stuck to the back of the joint as well as the sides, can’t stretch, and tears at the first real movement. Backing sets the depth and stops that.
Keep an eye out for these signs:
- Torn expansion joints
- Gaps opening along the back of the worktop
- Caulk or the wrong sealant used in a wet area
- A second bead peeling off the first
For an older house near a landmark such as Church and Churchyard, timber floors under older bathrooms flex, so joints need a sealant that moves with them.
