Frequently Asked Questions

Our company has been operating for over 10 years, with a team bringing more than 40 years of combined industry experience.

Yes, we are fully certified installers of Mapei Kerapoxy Grout.

We hold a 5-star rating on Google, based on over 580 customer reviews.

Yes. We provide warranties on our epoxy grout and silicone work, subject to the relevant terms and conditions.
Our epoxy grout has a 10-year limited replacement warranty for cracks or breaks, while our silicone has a 2-year limited replacement warranty for splits or breaks.
We believe providing a clear warranty is an important part of standing behind the work we do.

The 10-year limited replacement warranty covers cracks or breaks in the epoxy grout, subject to the applicable terms and conditions.
It is worth understanding that a grout warranty isn’t a guarantee against every possible problem that can occur in a shower. The condition of the underlying structure and other factors can also affect the performance of a tiled area.

Alpha Sealed WA provides a 2-year limited replacement warranty covering splits or breaks in the silicone, subject to the applicable warranty terms.
The warranty relates specifically to the silicone installation and shouldn’t be confused with a guarantee covering unrelated plumbing, structural or waterproofing problems.

Our warranty applies to the specific grout and silicone work covered by the warranty terms. It doesn’t mean that every problem that subsequently appears in a bathroom is automatically covered.
For example, plumbing issues, structural movement or problems with underlying waterproofing can have causes unrelated to the grout or silicone. The full warranty terms should always be referred to for the specific inclusions and exclusions.

There’s no sensible one-size-fits-all price for shower regrouting because the condition of the shower can make a big difference to the amount of work involved.
We look at the size of the shower, the condition of the existing grout and silicone, how much preparation is required and the overall condition of the area. Once we’ve seen the shower, we can provide a clear quote rather than giving you a price that may not reflect the work actually required.

It depends on what’s actually causing the leak.
A shower that needs some old silicone replaced is a very different job from one requiring extensive regrouting and other repairs. That’s why we prefer to inspect the shower before providing a price. It also means we’re quoting on the work you actually need rather than guessing from a few photographs.

Yes. We provide free, no-obligation assessments and quotes.
The idea is straightforward: we’ll look at the problem, explain what we believe needs to be done and provide a price. You can then decide whether you’d like to proceed. There’s no obligation to use our services simply because we’ve provided a quote.

Photos can certainly be useful, particularly for getting an initial idea of the condition of the shower.
The problem is that a photograph doesn’t always show cracked grout, loose silicone or the condition of the surrounding areas clearly enough to diagnose a leak. Where possible, we’d prefer to inspect the shower in person so that we’re quoting on the actual job rather than making assumptions from a photograph.

Two showers that look similar at first glance can require quite different amounts of work.
The size of the shower is only part of the equation. We also need to consider how much old grout has to be removed, the condition of the silicone, the amount of preparation required, access and the overall condition of the tiled area. That’s why we assess each job individually.

We start by looking at the shower as a whole rather than immediately assuming that the grout is the problem.
We check the condition of the grout and silicone, look closely at corners and junctions, inspect around the shower screen and look for visible signs of moisture or deterioration. From there, we can explain what we believe is happening and what we recommend doing about it.

There isn’t always one obvious thing to look at. That’s why experience matters.
We look at the grout, silicone, shower screen, corners, wall-to-floor junctions and surrounding areas, as well as any visible signs of water damage. We’ve worked on a lot of leaking showers over the years, so we’re familiar with the common areas where problems develop. If something looks like it may be a plumbing or more significant waterproofing issue, we’ll tell you rather than simply recommending regrouting.

Not necessarily, and this is one of the questions we get asked quite often.
Where the tiles are sound and the problem is associated with deteriorated grout and silicone, the shower can often be repaired without removing the existing tiles. This can save a considerable amount of mess, time and expense compared with stripping out the entire shower.
Of course, not every shower can be repaired this way. If there is a more serious underlying problem, we’ll explain that before any work starts.

Yes. We’re working in your home, so we understand that you don’t want the rest of your bathroom covered in dust and mess.
We take care around the work area and aim to keep disruption to a minimum. Preparation and clean-up are both part of doing the job properly, not something that should be left to the customer.

Yes. We don’t consider the job finished just because the grout has been installed.
Once the work is complete, we clean up the work area and leave the shower looking neat and presentable. It’s something that sounds obvious, but it’s important to us and it’s regularly mentioned by our customers in their reviews.

If we uncover something that wasn’t obvious during the initial inspection, we’ll explain it to you before carrying out additional work.
We’d rather have an honest conversation about what we’ve found than simply add work to the bill. If something needs attention, we’ll explain why, what the options are and what it is likely to cost before proceeding.

Absolutely.
We’re specialists in regrouting and leaking shower repairs, but that doesn’t mean every shower needs to be regrouted. If we inspect your shower and believe the existing grout is still in good condition, we’ll tell you.
We’d rather recommend the right solution than sell you work that isn’t necessary. That’s how we believe a good service business should operate.

I’d look beyond the cheapest quote.
Ask how much experience the company has specifically with shower regrouting, what products they use, how the old grout is removed, whether they provide a warranty and whether they have genuine customer reviews.
Regrouting might look like a relatively simple job, but the preparation and application can make a big difference to the result. A company that specialises in the work should be able to explain exactly what they are recommending and why.

Regrouting isn’t simply a matter of putting new material between the tiles. Before starting, you need to understand why the existing grout has failed and whether there are other issues contributing to the problem.
A specialist regrouting company spends its time dealing with tiled wet areas, leaking showers and deteriorated grout. That experience can be particularly valuable when the problem isn’t immediately obvious or when you’re trying to avoid an unnecessary bathroom renovation.

Look for evidence rather than just claims on a website.
Customer reviews, examples of completed work, years of experience, product certifications, warranties and clear information about the company’s process can all help. At Alpha Sealed WA, we’ve been specialising in this type of work for more than 10 years, our senior team has more than 40 years of combined experience, and we’re a certified installer of Mapei Kerapoxy Grout.

In our experience, preparation is one of the biggest factors affecting the finished result.
The old deteriorated grout needs to be properly removed before the new grout is installed. Simply spreading new grout over the top of old, damaged material may look fine initially, but it doesn’t provide the same foundation for a long-lasting repair.
Taking the time to prepare the joints properly is more work, but it’s an important part of doing the job properly.

The most common causes are cracked grout, deteriorated silicone sealant, failed waterproofing membranes, or leaking pipes behind the wall. Movement in the building structure can also contribute over time.

Signs include water stains on adjacent walls or ceilings, musty smells, peeling paint, swollen skirting boards, or damp carpet near the bathroom. A regrouting company, plumber, or leak detection specialist can confirm the source.

Yes, in many cases you can. Non-invasive methods like regrouting, resealing, or applying an epoxy sealant system can fix surface leaks without removing tiles. However, underlying structural or waterproofing issues may require tile removal.

If the leak is from pipes, a licensed plumber is needed. If the issue is with grout, sealant, or the waterproofing membrane, a regrouting company is more appropriate.

Generally, insurance covers sudden water damage, but not gradual leaks or lack of maintenance. Some policies may cover repairs to damage caused by the leak but not the cost to fix the shower itself. Check your PDS (Product Disclosure Statement).

Regrouting a standard sized shower typically takes between 4 to 6 hours.

Regrouting can fix surface-level leaks caused by deteriorated grout, but it won’t resolve leaks from failed waterproofing or plumbing behind the wall. A professional inspection is recommended to identify the root cause.

Use a neutral-cure silicone specifically designed for bathrooms. It should be mould-resistant and compliant with Australian Standards (AS 3740 for waterproofing).

 – Reseal joints every 1–2 years
 – Repair cracked grout promptly
 – Use a shower screen that prevents splashing
 – Avoid harsh chemicals that damage sealants
 – Ensure proper slope for drainage

A leaking shower isn’t always as obvious as water running across the bathroom floor. In fact, some of the first signs we see are recurring mould, a musty smell, cracked grout, deteriorating silicone, damp patches or water staining on the wall or ceiling next to or below the shower.
If you’ve noticed one or more of these problems, it doesn’t necessarily mean you have a major waterproofing failure. It could be something as straightforward as deteriorated grout or silicone. The important thing is to have the shower assessed before assuming you need a complete renovation.

Yes. We’ve seen plenty of showers where there is no obvious water on the bathroom floor, yet there are signs that moisture is getting where it shouldn’t.
Water can gradually work its way through gaps in deteriorated grout, silicone or other areas of the shower. You might first notice a damp smell, mould that keeps returning or staining on an adjoining wall. These signs are worth investigating rather than waiting until you have a much more obvious leak.

A musty smell can sometimes be a sign that moisture is lingering somewhere it shouldn’t. Poor bathroom ventilation and condensation can also cause musty smells, so it isn’t automatically an indication of a leaking shower.
However, if the smell keeps coming back despite cleaning and is accompanied by mould, cracked grout, deteriorating silicone or dampness, we’d recommend having the shower checked. The smell itself isn’t the diagnosis, but it can be a useful warning sign.

If you’re constantly cleaning mould from the same areas, it’s worth looking beyond the mould itself. Bathrooms naturally have a lot of moisture, but recurring mould can be made worse by poor ventilation, condensation and areas where water isn’t drying properly.
We often see mould developing around old silicone and deteriorated grout. Cleaning the surface may remove the mould temporarily, but if the underlying area has deteriorated, the problem can keep returning. Good ventilation and regular cleaning are still important even after repairs have been completed.

Yes. It’s one of the issues we regularly come across when looking at older showers.
Once grout starts cracking, crumbling or separating, water can find its way through areas that should be protected. That doesn’t mean every shower with cracked grout has a failed waterproofing membrane, though. We look at the overall condition of the shower before deciding whether regrouting is actually the appropriate solution.

Yes. Silicone is particularly important around shower screens, corners, wall-to-floor junctions and other areas where different surfaces meet.
Over time, silicone can shrink, split, crack or pull away from the surface. Once that happens, water can get through the gap. Replacing old silicone is a relatively straightforward repair, but it’s important to make sure the new seal is applied properly and that any underlying issues are also considered.

They can, although a loose tile doesn’t automatically mean the shower is leaking.
Tiles can become loose for a number of reasons, including movement, adhesive failure or problems with the original installation. However, if you’re seeing loose tiles together with cracked grout, mould, dampness or other signs of water penetration, we’d recommend getting the area checked rather than assuming it’s just a loose tile.

Yes. Water that gets through a shower floor or surrounding structure can eventually make its way into the area below.
The first sign might be a small stain or patch of discolouration on the ceiling. Left long enough, ongoing moisture can cause much more significant damage. If you’ve noticed staining below a bathroom, it’s worth investigating the source sooner rather than later.

Yes, and this can sometimes make diagnosing a shower leak confusing.
Water doesn’t necessarily appear directly underneath the point where it enters. It can travel through building materials before becoming visible on an adjoining wall or another part of the property. If you notice dampness, staining, bubbling paint or mould on the wall next to a shower, the shower should be one of the areas investigated.

This isn’t always something you can determine just by looking at the affected area. A leaking pipe and a leaking shower can produce very similar symptoms.
When we inspect a shower, we look at the condition of the grout, silicone, shower screen, junctions and surrounding areas for signs that water is escaping from the shower itself. If the evidence points towards a plumbing problem, a licensed plumber may be required instead. It’s better to identify the likely cause before starting work.

Bathroom regrouting is the process of removing old, damaged grout between tiles and replacing it with fresh grout. It improves the appearance and functionality of tiled surfaces, especially in areas like showers, bathtubs, and floors.

You may need to regrout if you notice cracked, discolored, or moldy grout, or if the grout is crumbling or missing in certain areas. These are signs that the grout has deteriorated and may no longer provide a proper seal.

It’s generally not recommended to regrout over existing grout. The old grout should be removed for the best results. Applying new grout over old grout can lead to uneven surfaces and poor adhesion.

To remove old grout, use a grout removal tool or a grout saw. You can also use a rotary tool with a grout removal attachment for quicker results. Be careful not to damage the tiles when scraping out the grout.

Regrouting a bathroom typically takes between 4 to 6 hours for a small area, or up to 1-2 days for larger bathrooms, depending on the complexity of the job and drying time for grout.

For bathrooms, it’s best to use cement-based grout for standard installations. For areas exposed to high moisture, such as showers, use epoxy or urethane grout, which are more resistant to water and stains.

Standard grout is a mixture of cement, water, and sand, which is porous and can absorb moisture, leading to potential mold growth. Epoxy grout is made from a resin and hardener, offering superior water resistance, stain resistance, and durability, but it is harder to work with and more expensive.

Yes, sealing your grout after regrouting helps protect it from moisture, stains, and mold. It’s particularly important in high-moisture areas like bathrooms. Wait 48 hours after regrouting before applying a grout sealer.

Yes, epoxy grout is an excellent choice for bathrooms, especially in high-moisture areas like showers. It’s more durable, water-resistant, and less prone to staining than standard grout.

Yes, you can regrout a bathroom yourself, but it requires patience, precision, and the right tools. If you’re comfortable with DIY projects, it can save money. However, if you’re unsure or dealing with complex areas, hiring a professional may be a better choice.

Bathrooms with standard (cement-based) grout typically need regrouting every 5 to 10 years, depending on moisture exposure and maintenance. In contrast, bathrooms with epoxy grout may not need regrouting for 15 years or more, as it is significantly more durable, water-resistant, and less prone to cracking or staining.

Commercial regrouting involves removing old, damaged grout and replacing it with new, durable grout to restore tiled surfaces. It’s essential for maintaining hygiene, preventing water damage, and extending the lifespan of tiled areas in high-traffic environments like hotels, gyms, and shopping centres. Property managers also rely on commercial regrouting to prepare properties for new tenants and maintain safe, presentable tiled areas for existing occupants.

Common signs include cracked or missing grout, mould growth, loose tiles, water leaks, or discoloured grout that won’t clean up. If left untreated, these issues can lead to structural damage and costly repairs.

Yes. In most cases, leaking showers can be repaired without removing tiles by regrouting and resealing the area. This is a cost-effective solution that minimises downtime for commercial properties.

We work with a wide range of facilities across Perth, including hotels, restaurants, schools, universities, hospitals, gyms, shopping centres, and public swimming pools, as well as strata and managed properties.

The timeframe depends on the size and condition of the area, but most jobs are completed quickly and efficiently to minimise disruption. We can also schedule work after hours or in stages for busy commercial sites.

In most cases, yes. Tile regrouting is significantly more affordable and less disruptive than retiling, while still delivering a fresh, clean appearance and restoring waterproof integrity.

When applied and maintained properly, professional regrouting and sealing with epoxy grout can last many years, even in high-use commercial environments. We exclusively use high-quality epoxy grout and materials designed for durability and long-term performance.

Yes. We work with property managers and facility operators across Perth to provide ongoing maintenance plans, helping prevent costly repairs and keeping tiled areas in top condition year-round.

Alpha Sealed WA is a trusted partner for commercial businesses and property managers across Perth, known for reliable service, minimal disruption, and long-lasting results. Our experience across a wide range of commercial environments means we understand the unique demands of high-traffic spaces.

Drying and curing times may vary, but we provide clear guidance on when areas can be safely used again. Epoxy grout systems typically allow for faster return to service compared to traditional grout.

We use epoxy grout because showers are a demanding environment. They’re constantly exposed to water, cleaning products, soap and general use.
Epoxy grout has very low porosity and is highly resistant to moisture and staining compared with traditional cement-based grout. We believe using a quality product is an important part of getting a result that will stand up to everyday use.

Epoxy grout has very low water absorption and is highly resistant to water, which makes it particularly well suited to showers and other wet areas.
However, it’s important not to confuse grout with the waterproofing membrane behind the tiles. Epoxy grout is one part of the shower system. It isn’t a substitute for properly installed underlying waterproofing.

Epoxy grout is much less porous than traditional cement grout, which means it is less likely to absorb moisture and become stained.
That doesn’t mean your shower can never develop mould. Mould can still grow on soap residue, dirt, silicone and other surfaces, particularly where ventilation is poor. Keeping the shower clean and well ventilated remains important.

Yes. Epoxy grout is well suited to shower floors and other wet areas when the correct product is selected and installed properly.
The existing tiles and grout joints also need to be suitable for the application. This is something we consider when assessing the shower rather than simply assuming the same product is appropriate for every situation.

It can be, depending on the particular balcony and how it has been constructed.
Balcony leaks can have several causes, so grout should not automatically be blamed. The condition of the tiles, joints and surrounding areas, as well as the underlying waterproofing, all need to be considered when determining the appropriate solution.

The grout is exposed to a lot more than people sometimes realise. It has to cope with moisture, cleaning, movement and everyday wear.
We’ve seen the difference that good materials and proper preparation can make. That’s why Alpha Sealed WA uses premium Mapei products rather than treating grout as simply something that fills the gaps between tiles.

The best approach is generally regular, gentle cleaning rather than using aggressive chemicals.
Warm soapy water and a soft-bristled brush are suitable for routine cleaning. Keeping soap residue and grime under control will help maintain the appearance of the new grout and reduce the conditions that encourage mould.

We recommend avoiding harsh chemicals and abrasive cleaning products that can affect grout, silicone or surrounding surfaces.
It’s tempting to reach for strong chemicals when a shower starts looking dirty, but regular gentle cleaning is usually a better approach. If you’re unsure about a particular cleaning product, check that it is suitable for the grout and sealant installed in your shower.

Repeated use of harsh chemicals such as bleach can contribute to deterioration or discolouration of some grout and sealant products.
For everyday shower cleaning, we’d recommend a gentler approach. You don’t need an aggressive chemical regime to keep a properly regrouted shower clean.

There’s no single trick that will prevent mould in every bathroom. Good ventilation, regular cleaning and reducing excess moisture all make a difference.
If mould is continually returning around the same grout or silicone joints, however, don’t just keep treating the surface. It’s worth checking whether the grout or silicone has deteriorated and whether moisture is contributing to the problem.

Look after it in much the same way you’d look after any other part of your bathroom. Keep the shower clean, avoid harsh chemicals, maintain good ventilation and don’t ignore damaged grout or silicone.
If you notice a crack, gap or deteriorating seal, dealing with it early is generally better than waiting until the problem has become much more extensive.

The new grout and sealants need time to cure before they are exposed to water.
For Alpha Sealed WA’s shower regrouting work, customers are generally advised to wait 24 hours before using the shower. We’ll provide the appropriate instructions when the work is completed.
