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.

The previous shower was done badly and ended up leaking into the timber underneath, so we needed it rebuilt properly from scratch. You can tell straight away this one’s been done with a lot more care. The falls to the drain are spot on, it looks clean, and the whole base feels solid. Honestly, such a relief to have it fixed properly by actual professionals. I very much recommend Daniel and Shiny Showers for your shower work :) Thank you Daniel and your amazing team.

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

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!

Put on new white grout which has made a huge difference to our shower tiles. Lucky it wasnt a leak as we cant find these tiles anywhere anymore. Daniel did a comprehensive leak detection test to make sure and it put my mind at ease before the job.

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.

From first in-person consult, to booking via their online system was easy and timely. Daniel came out to do a full regrout with epoxy / re-silicone all completed in a day. I can now shower with ease without mouldy silicone and failed grout!
I will definitely use them again for our upstairs bathrooms 😊

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!!

I requested a complete shower rebuild of my shower in an older style apartment block. Daniel, the installer, was a great communicator and explained the process, every step of the way. This company is professional, experienced, and does high-quality tiling and certificated waterproofing work. The result was a very smart looking ultra modern shower. If ever I need a shower rebuild service into the future, I will be calling them again.

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!
