Persistent shower mould is often a sign of moisture retention, failed sealing, or poor ventilation. Treating only the surface rarely lasts, so it is important to fix the underlying cause.
Everything you need to know about mould in showers
Shower mould can return quickly when moisture is trapped in grout lines, silicone joints, or poorly ventilated areas. Long-term results come from cleaning plus corrective repair where needed.
Why it happens
Moisture, poor airflow and failed joints create ideal conditions
Mould thrives where water lingers. Failed silicone, porous grout, and limited ventilation all increase the chance of recurrent mould growth.
What it looks like
Black spotting, staining and musty odours
Common signs include dark specks in corners, discoloured grout, mouldy silicone lines, and a persistent damp smell after shower use.
If you leave it
Mould can spread and become harder to remove
Ignoring shower mould can lead to deeper contamination in porous areas and increased health concerns for people sensitive to damp indoor environments.
How we approach it
We treat visible mould and the moisture source
Effective mould in shower repair includes replacing contaminated sealant, improving sealing, and addressing moisture entry points so mould is less likely to return.
Why this matters
"Shower mould keeps returning when moisture issues are not fixed at the source."
Professional mould treatment
Lasting mould control needs cleaning plus corrective shower repairs
Surface cleaning can improve appearance temporarily, but recurrent mould usually means joints, grout, loose tiles, or moisture management need attention. We focus on long-term outcomes, not short-term masking.
Contaminated silicone and affected joints are properly removed
Moisture-prone zones are assessed and repaired where needed
New sealing and aftercare advice help reduce mould recurrence
We check silicone lines, grout joints, and ventilation patterns to identify why mould keeps returning.
2
Remove contaminated materials
Mould-affected sealants and unstable joint materials are removed so repairs start on a clean base.
3
Repair and reseal
We regrout or reseal where needed to restore water resistance and reduce conditions that support mould growth.
4
Provide prevention guidance
You get practical maintenance and ventilation advice to help keep the shower cleaner and mould-resistant over time.

Our 10-year warranty
We provide a 10-year warranty on eligible repair work. We explain the warranty terms before work begins, so you know what is covered. If a covered issue comes up within 10 years, we will return and address it under our warranty terms.
Straightforward answers on causes, health concerns, and mould removal vs repair.
If sealing has failed or moisture remains trapped in grout and joints, mould can return quickly. Cleaning helps visually, but leaking shower repairs may be needed for long-term control.
Mould can affect indoor air quality and may aggravate allergies or respiratory sensitivities. Prompt treatment and moisture control are recommended.
Many showers need both. Surface mould removal handles immediate contamination, while sealing and grout repairs help prevent ongoing regrowth.

There was a lot of mould and rotten wood underneath, so they had to remove the shower base and redo the waterproofing properly! It made a huge difference! I've got before and after photos and the improvement is very clear! They also sorted a few cracked tiles in another bathroom as part of a separate shower repair. Everything was done quickly and Daniel was very professional. 5/5 stars!

Every step was performed thoroughly and with care. Daniel explained each step from the grout used down to the tile sealer. The grout lines are clean and the tile surfaces restored to their former sheen. The screen doors were cleaned and the shower door moulding replaced with new. We picked Daniel because of his tiling background and we wanted someone that has the expertise to fix any issues if they pop up during the job. Happy to recommend Shiny Shower!!

Thanks Daniel for respecting our home & go the second mile to delay your lunch to ensure the epoxy sets well, prioritizing results above convenience.

He just finished resealing and regrouting both of our shower bases with epoxy grout, and the craftsmanship is next-level. The job was completed to such a high standard, and the cleanliness throughout the process was incredible, not a speck of mess left behind.
If your shower needs repair, don’t hesitate or risk getting caught out with sub-contractors. Having the owner himself complete the job makes all the difference. Booking Daniel is easily the best decision you can make to get your showers looking brand new again! 🚿✨

We experienced full transparency on the quote too, a 24 hour window for 10% discount, deposit & balance of payment. Nothing left in doubt. No uncertainty here.
Only time will tell whether the quality of the waterproof epoxy & low maintenance will prove true. We were assured it will.
There is one sad thing though - Daniel delayed taking his lunch until the job was well completed & the epoxy well set! Thanks, Daniel, for your "no compromise" attitude towards excellent results!

He arrived on time each time which is no feat and was much appreciated as we negotiated home and work life. Daniel also did a fantastic job with our bathrooms - each having several issues: water damaged tiles and minor leaks (Causing various flow on effects to ceilings and floors). I highly recommend Daniel. Our bathrooms look great and more importantly are waterproofed and sealed.

What really stood out was going above and beyond! They even did the silicone around my basin at no extra cost, which was such a thoughtful touch and made a big difference to the overall finish.
Professional, efficient, and genuinely lovely to deal with. I’d highly recommend them to anyone needing grouting or sealing work done!

Excellent job, professionally done. Attention to detail, friendly service, you can't ask for more. The house was brand new in 1995, this is the second job to freshen up the shower, to re-grout and eradicate mould. Many thanks!!!

The space is pretty narrow but they made it feel a lot more open and modern. Tiles are straight, finish is neat, and the drainage works properly now which was our biggest issue before. They were easy to deal with, turned up when they said they would, and didn’t leave a mess behind. Happy with the result.
