Regrouting a Shower for Leak Prevention and Durability

Have you noticed water gathering on the bathroom floor outside your shower? You might see cracked or discoloured grout lines, and despite your diligent cleaning efforts, a persistent musty smell prevails. Perhaps you’ve observed bubbling paint on the nearby wall or the wooden door frame swelling due to excess moisture.

It’s easy to assume that a pipe has ruptured behind the wall. in many cases, water seeps through damaged grout and deteriorated silicone. A simple regrouting and resealing can effectively address that leak without the need for any tile removal.

This guide explains when regrouting your shower can successfully fix a leak and when it might not suffice. You will also discover the regrouting process employed by Leaking Showers Sealed, including how long you should wait before using the shower again. If you suspect that the grout is contributing to your issue, our specialised shower regrouting page provides a detailed overview of our services in North Richmond, the Hills District, and the North Shore.

Can Regrouting Effectively Stop My Shower Leak?

• Regrouting can effectively halt leaks when water escapes through damaged grout or silicone.
• We remove the old grout and replace it with Ardex EG15 epoxy grout, a non-porous material, while resealing corners and junctions with Ardex neutral cure silicone.
• Your tiles stay intact, allowing you to repair a leaking shower without extensive renovations or removing tiles.
• If the leak originates from a faulty pipe, drain, or tap, you will need to consult a plumber. A damaged membrane beneath the tiles will require tile removal, meaning a regrout alone will not resolve these issues.
• It is advisable to wait a minimum of 24 hours before using the shower again.

The Importance of Shower Regrouting Explained

Shower regrouting involves the removal of old, cracked, or mouldy grout from between your shower tiles, followed by the application of new grout to restore the seal between the joints. At Leaking Showers Sealed, we use Ardex EG15 epoxy grout, which is non-porous and prevents water and mould from penetrating, unlike traditional cement grout.

Over time, grout deteriorates due to heat from hot water, exposure to cleaning chemicals, and minor shifts in structure. This degradation results in cracks and pinholes that allow water to seep through the joints, even when the tiles themselves seem unaffected. Often, this damage remains unnoticed as water accumulates behind the tiles and beneath the shower floor.

Regrouting restores these joints, re-establishing the shower’s watertight integrity. It also removes unsightly stained grout lines that can make a pristine bathroom look outdated, all without the expense and disruption of a full renovation.

Will Regrouting My Shower Resolve the Leaks?

Regrouting effectively addresses leaks when water escapes through compromised grout or silicone, which are frequent culprits of shower leaks. The first step is to identify the source of the water to determine if regrouting is the appropriate solution.

When Is Regrouting and Resealing the Optimal Solution?

Regrouting and resealing is the ideal choice when you notice cracked, crumbling, or missing grout, or mould that recurs after cleaning. This method is also effective if the silicone around corners and the shower base has split or detached. In these cases, the tiles remain intact while water leaks through the joints.

When Should You Contact a Plumber Instead of Regrouting?

If the leak originates from a pipe within the wall, the shower drain, or a tap, regrouting will not resolve the problem. We work alongside plumbers, and if our inspection indicates an issue with a pipe, drain, or tap, we will provide a thorough explanation and refer you to a plumber for further assistance.

What If the Waterproofing Membrane Beneath the Tiles Is Damaged?

A waterproofing membrane is located behind the tiles and under the shower floor. Continuous exposure to water through damaged grout can compromise this membrane. Replacing a failing membrane involves removing tiles, categorising it as renovation work that we do not undertake.

Andreas, holding NSW licence 89111C, is an expert in waterproofing. Our team is trained to identify a compromised membrane. If we discover during our inspection that your shower requires more than just a regrout, we will inform you prior to beginning any work.

Addressing issues at the first signs of trouble helps protect the membrane. Fresh epoxy grout and new silicone create a barrier against water, making it crucial to address cracked grout before further damage occurs.

How to Identify the Need for Shower Regrouting

Watch for the following signs that may indicate your shower is leaking through the grout and silicone:

• Cracked, loose, or missing grout between the tiles
• Mould that quickly returns after cleaning
• Damp odours or visible moisture damage near the shower
• Water pooling outside the shower or leaking into adjacent areas
• Bubbling paint, discoloured walls, or soft floorboards
• Tiles that feel loose or sound hollow when tapped

If you notice any of these symptoms, it is likely that the grout and silicone are no longer effectively retaining water within the shower. Tiles that sound hollow when tapped, known as drummy tiles, may require refixing before the shower can be resealed, and we check for these during our inspection.

What to Anticipate During the Regrouting Process with Leaking Showers Sealed

The regrouting process at Leaking Showers Sealed consists of five essential steps, ensuring your tiles remain undisturbed throughout.

Step 1: Inspecting the Shower and Identifying the Leak Source

We perform a thorough examination of the grout, silicone, tiles, and surrounding areas to pinpoint where the water is escaping. If our inspection reveals an issue with a pipe, drain, or tap, we will inform you before scheduling any regrouting.

Step 2: Removing Old Grout and Silicone

We carefully cut out the old grout and remove all existing silicone, including any layers applied over previous silicone. New grout cannot bond effectively to old grout, making it crucial to start with a clean slate.

Step 3: Thoroughly Cleaning the Tiles and Exposed Joints

We ensure that the tiles and empty joints are meticulously cleaned to eliminate soap scum, dust, and mould, guaranteeing that the new grout adheres effectively to a clean surface.

Step 4: Applying Epoxy Grout to Regrout the Shower

We fill the joints with Ardex EG15 epoxy grout. For sealing the shower base, we regrout the shower floor, the floor-to-wall junction, and the perimeter. For a complete shower seal, we also regrout every wall grout line.

Step 5: Resealing Corners, Junctions, and Tap Flanges

We apply Ardex ST neutral cure silicone to reseal internal corners and junctions. For a comprehensive shower seal, we ensure the tap flanges are also sealed.

Typically, sealing the shower base takes approximately 3 to 4 hours to complete, while a full shower seal for both walls and floor generally requires 4 to 5 hours. You must wait at least 24 hours before using the shower again to allow the grout and silicone to cure effectively.

Can Regrouting Eliminate Shower Mould?

Regrouting effectively removes mould that has infiltrated the grout, as the mouldy grout is entirely replaced. Surface cleaning with bleach or mould sprays only targets the upper layer, allowing mould to return since it resides within the grout where water is trapped. For more information on the factors that cause shower grout to become stained and damaged, please refer to our guide.

Can Regrouting Help You Avoid a Complete Bathroom Renovation?

For many homeowners, regrouting offers a practical solution to postpone or avoid a complete bathroom renovation. If the tiles are in good condition and the leak is traced back to the grout and silicone, a regrout and reseal will restore the shower’s watertight integrity. This approach also provides you with additional time to save for a future renovation.

A regrout, reseal, and thorough clean can also serve as an effective refresh before listing a home for sale or for landlords between tenant occupations. Our article on regrouting a shower as a cost-effective renovation illustrates how significantly a regrout can enhance a bathroom’s appearance.

Is DIY Regrouting a Shower a Viable Option?

Although DIY grout kits are readily available at hardware stores, regrouting a shower correctly is more intricate than it appears. Without the appropriate tools and expertise, you risk:

• Damaging or cracking tiles while removing old grout
• Leaving remnants of old grout in the joints, preventing proper bonding of new grout
• Overlooking silicone joints, which are common leak sources
• Failing to identify a leak from a pipe or a compromised membrane

If you are unsure about the source of the water, it is advisable to have the shower inspected before purchasing a DIY kit.

What Is the Cost of Shower Regrouting?

The cost of regrouting a shower varies based on several factors:

• Tile size, as smaller mosaics and 100mm tiles have more grout lines compared to larger 300mm or 600mm tiles
• The dimensions and layout of the shower, including features such as double showers, niches, and additional corners
• The condition of the grout and silicone, including issues like extensive mould, silicone layered over old silicone, or previous repairs needing removal
• Drummy or loose tiles that require refixing prior to resealing the shower

Regrouting is significantly more cost-effective than a full bathroom renovation or retiling. For a cost estimate, please send photos of the shower floor, walls, and the entire shower to sales@leakingshowerssealed.com.au, or call 1300 815 512.

Frequently Asked Questions About Shower Regrouting

How long does the regrouting process take?
A shower base seal typically requires about 3 to 4 hours on site, while a complete shower seal for both walls and floor takes around 4 to 5 hours. Please allow at least 24 hours before using the shower again.

<a href=”https://writebuff.com/regrouting-a-shower-a-smart-budget-renovation-idea/”>Will regrouting resolve a leak?</a>
Yes, if the leak is due to damaged grout or silicone. Regrouting will not address leaks from a pipe, drain, or tap, which require a plumber, nor will it rectify a failed membrane that necessitates tile removal.

How often should a shower be regrouted?
The frequency of regrouting depends on the type of grout used, the bathroom’s ventilation, and the cleaning practices employed. Signs indicating the need for regrouting include cracked grout, recurring mould, and persistent damp odours. Our article on how long shower regrouting lasts discusses the factors that influence this.

Can new grout be applied over old grout?
No. New grout applied over existing grout will not bond properly and will not fix the leak. All old grout must be removed before regrouting the shower.

<a href="https://homerenonews.com.au/shower-reseal-genuine-solution-or-just-a-quick-fix-5/">Is regrouting covered by warranty?</a>
Yes. A regrout and reseal includes a 10-year warranty on Ardex products and a 7-year workmanship warranty from Leaking Showers Sealed, contingent upon a site assessment.
