Whether you’ve spotted a wet patch, mould, or pooling water, our Newcastle plumbing team will sort it quickly and fix it right the first time.
Why Newcastle Homeowners Choose Regrouting Over Full Renovation
A leaking shower used to mean a full bathroom renovation from the ground up. Tile regrouting now costs around a tenth of a full rebuild, and the bathroom is back in service within 36 hours rather than out of action for two to three weeks.
The reason a renovation runs so high is that the waterproofing membrane runs continuously, underneath the floor and up behind the wall tiles around the whole bathroom. Once one section is lifted, the rest usually have to come up with it. In the video, Mick walks through why a regrout and reseal avoids that and how our team gets in and out in a day.
Most leaking showers in Newcastle do not need a renovation, they need an accurate diagnosis. The video shows how our team identifies the cause before any tiles are disturbed.

The Signs of a Leaking Shower
The earliest signs your shower is leaking behind the wall are easy to miss. Left alone, a failing seal or grout line can lead to structural damage, mould and mildew through the wall cavity, and water bills that climb without explanation. Our team traces shower leaks with moisture meters and non-invasive testing before any tile is lifted, and the earlier the leak is found, the smaller the repair will be.
Why Failed Waterproofing is almost always
the cause
Most leaking showers in Newcastle homes turn out to be waterproofing failures rather than plumbing leaks. Water seeps through the grout lines, gets underneath the tiles, and starts rotting out the substrate. The first sign for many homeowners is water damage on the exterior wall of the adjoining room, rather than anything obvious in the shower itself.
The video walks through the common signs to look out for, including water damage on exterior walls and the void areas around strip drains, which our team treats as one of the main leak points to check before anything else.
If any of those signs match what you are seeing at home, the next step is a non-invasive inspection rather than ripping up the bathroom.

Inside Our Shower Repair Process
Why it beats ripping out the tiles
Most shower repair jobs start with one question: What signs are you seeing? In the job covered, the client had a rotting door jamb, which is one of the classic indicators that the grout and waterproofing have failed, and water has tracked through the substrate.
The video walks through how our team grinds out the floor joint, packs it with epoxy, and seals the grout lines to stop water from reaching the failed membrane. The result is a watertight shower for a fraction of the cost of stripping the tiles.
The same approach applies whether your shower is in a Cooks Hill terrace or a Charlestown weatherboard.
Replacing One Shower in a Renovation
The Problem and the Smarter Solution
When the waterproofing membrane has failed, a renovation cannot simply replace the shower in isolation. A new membrane cannot be joined to an old one, painted onto it, or installed in the shower alone, which is why a textbook fix usually means stripping the entire bathroom for tens of thousands of dollars.
In the video, Mick stands in front of a rotted-out membrane and shows how our team works around this. By grinding out the grout, sealing the inside with epoxy, and reworking the strip drain voids, the bathroom stays in place, and the cost stays a fraction of a full bathroom renovation.
If you have already paid for a repair that has not held, the right next step is a second opinion from a fully licensed plumber rather than a quote for a new bathroom.

Frequently Asked Questions
How do I know if my shower is leaking?
Peeling paint, mould, damp walls and water pooling outside the shower are the usual signs. Others are easier to miss: water damage on the wall of the next room, a rotting door jamb, or a water bill that climbs without explanation. If you're not sure, contact our team for a non-invasive inspection, as the earlier the leak is found, the smaller the repair.
Do I need a plumber to fix a leaking shower?
Usually, yes. Most leaking showers are waterproofing failures rather than plumbing leaks, with water getting through the grout lines, under the tiles and into the substrate. A licensed plumber traces the source with moisture meters and non-invasive testing before any tile is lifted, checks the grout, seals, pipes, fittings and strip drain voids, and fixes only what's needed.
Can I repair my shower myself?
Unless it's a simple silicone job, most shower repairs involve plumbing, waterproofing and tiling work that's best left to a licensed plumber. DIY fixes tend to mask the problem and can lead to bigger issues later. If a previous repair hasn't held, get a second opinion from a licensed plumber before paying for a new bathroom.
Do you need to remove the tiles to fix a leaking shower?
In most cases, no. We grind out the floor joint, pack it with epoxy and seal the grout lines so water can't reach the failed membrane underneath, reworking the strip drain voids where needed. The tiles stay in place, and every repair comes with a guarantee.
How long does a shower repair take?
A regrout and reseal usually has our team in and out in a day, with the bathroom back in service within 36 hours, compared with two to three weeks for a full renovation. Same-day assessments are available.
How much does it cost to fix a shower?
It depends on the cause, so we inspect first and give you a fixed-price quote with no hidden fees. A regrout and reseal costs around a tenth of a full bathroom renovation.
Why can't a renovation replace just the shower?
The waterproofing membrane runs continuously under the floor and behind the wall tiles of the whole bathroom. A new membrane can't be joined to an old one, painted onto it or installed in the shower alone, so lifting one section usually means lifting the rest. That's why a textbook fix means stripping the entire bathroom, for tens of thousands of dollars.
