What Does Bathroom Resealing Entail?

Bathroom resealing involves removing and replacing the old or damaged sealant (usually silicone caulk) around fixtures in your bathroom to restore a watertight barrier. Over time, the seals around your shower, tub, sink, and other joints can crack, peel or grow mouldy due to constant exposure to water and humidity. Once seals fail, water can sneak into gaps and crevices, leading to hidden leaks and damage. This is where professional resealing comes in.
Our resealing process is efficient and often does not require removing tiles, making it a convenient and cost-effective solution.
Why Does Bathroom Resealing Matter?

Proper sealing is essential in any wet area. When seals are intact and done to code, they keep moisture confined to places with proper drains. If seals degrade, you could face:
- Leaks and Water Damage: Water seeping behind tiles or fixtures can rot wooden framing, damage plasterboard, or drip to lower levels. Resealing stops leaks at the source before they cause expensive structural repairs.
- Mould and Mildew: Broken seals trap moisture, creating a breeding ground for mould and mildew. These not only look and smell bad but can also pose health risks. Fresh sealant with anti-mould properties helps keep your bathroom hygienic.
- Loss of Waterproofing Integrity: Bathrooms are built with waterproofing membranes and sealants as per Australian Standards (AS 3740 for wet areas). When part of that system (like the silicone seals) fails, the entire waterproofing is compromised. Resealing restores the integrity and compliance of your bathroom’s waterproofing.
- Deterioration of Fixtures and Tiles: Constant water exposure at unsealed joints can cause tiles to lift or fixtures to loosen. Keeping seals in good condition preserves the lifespan of your bathroom fittings and finishes.
In short, professional bathroom resealing addresses common issues like leaking showers, bath leaks, mouldy silicone, and water-damaged corners, giving your bathroom a fresh start without the cost of a full renovation. Professional resealing also includes comprehensive leak repairs to ensure your bathroom remains watertight and damage-free.
Benefits of Professional Bathroom Resealing

Opting for a professional reseal of your bathroom comes with a host of benefits that DIY fixes often can’t guarantee. We offer a free quote and competitive pricing to ensure you get the best value for your bathroom resealing needs.
Here are some key advantages of using Canberra Plumbing’s expert resealing service:
- Stop Leaks at the Source: Our experienced plumbers will effectively seal all gaps around tubs, showers, basins, and toilets, preventing ongoing leaks. This protects your walls, floors, and cabinetry from water damage before it gets out of hand.
- Prevent Costly Water Damage: By resealing early, you avoid bigger problems like rotting subfloors, structural repairs, or mould remediation. A quick reseal now can save you thousands in future repair bills, as well as the headache of major bathroom works.
- Hygienic and Mould-Free Bathroom: We use mould-resistant silicone sealants that inhibit mildew growth. Professional removal of old grimy sealant and replacement with fresh, clean lines instantly improves your bathroom’s cleanliness and appearance. Say goodbye to black mouldy corners and hello to a cleaner, healthier bathroom.
- High-Quality Materials for Durability: We only use premium-grade, bathroom-specific sealants that are designed for wet area use in Australian homes. These quality materials are flexible (to handle expansion and contraction), anti-fungal, and formulated to last. A professional reseal gives you a durable finish that can withstand daily use and Canberra’s climate, far longer than hardware store quick fixes.
- Compliance with Waterproofing Standards: Our team follows industry best practices and adheres to Australian waterproofing standards (such as AS 3740) during the resealing process. This means your bathroom will not only be leak-free but also compliant with building regulations for wet areas. Proper resealing maintains the warranty of your bathroom waterproofing and ensures any future buyers or inspectors see a job done right.
- Peace of Mind and Warranty: When done by Canberra Plumbing, you can trust that the job is done correctly the first time. We stand by our workmanship, if any issues arise with our resealing, we’ll make it right. Professional resealing gives you the peace of mind that you’ve invested in a long-term solution, not just a temporary patch.

Our Bathroom Resealing Process
At Canberra Plumbing, we follow a step-by-step resealing process to guarantee a thorough job and long-lasting results. Here’s what you can expect when you book our bathroom resealing service:
- Initial Inspection & Consultation: Our plumber will first assess your bathroom to identify all areas where the seals are failing or vulnerable. We check around showers, tubs, sinks, toilets, and anywhere water could escape. We’ll discuss our findings with you, answer any questions, and recommend the best resealing solution. If we suspect any deeper issues (like a plumbing leak or failing waterproof membrane), we’ll inform you of additional steps beyond just re-sealing.
- Preparation, Removing Old Sealant: Preparation is key to a quality reseal. We carefully remove all the old silicone or caulking from the affected joints using specialised tools. Any loose or crumbling grout in corners may also be scraped out if it’s affecting the seal line. The area is then cleaned thoroughly to eliminate soap scum, mould, dirt, and debris. We make sure surfaces are dry and clean, because a sealant can only adhere properly to a clean, dry surface. (If mould is present, we treat the area with an appropriate cleaner to kill spores before resealing.)
- Surface Priming (If Required): In some cases, especially with certain types of tiles or shower materials, we apply a primer to the joints to improve sealant adhesion. This step ensures the new seal will bond strongly and creates a water-tight seal that endures. We use primers and materials that are compatible with Australian building materials.
- Professional Resealing Application: Once prep is done, our plumber applies a fresh bead of high-quality silicone sealant to all necessary joints and gaps. We use a bathroom-grade, neutral cure silicone that is anti-fungal (to resist mould) and flexible (to handle expansion or movement). Using steady, expert technique, we lay down smooth, even seals around your bathtub edges, shower screen, vanity, floor joints, and anywhere needed. The sealant is tooled neatly (usually with a finishing tool or finger in a glove) to ensure it is pressed in and shaped correctly for maximum hold and a clean look.
- Curing Time & Clean-Up: After application, the new sealant needs time to cure (dry and set). We’ll advise you on the necessary curing time – typically, silicone needs around 24 hours to fully cure before it should get wet. We perform a tidy clean-up of any excess sealant and ensure your bathroom is left as clean (or cleaner) than we found it. We’ll also double-check all seals for a consistent finish.
- Final Inspection & Customer Walk-through: Finally, we inspect the newly sealed areas to make sure every gap is sealed and the work meets our quality standards. We’ll have you take a look as well. Our plumber will inform you of any care instructions (like keeping the area dry for the curing period, and how to clean the new seals gently going forward). We make sure you’re satisfied with the result. Once cured, your bathroom is ready to use with its new, improved waterproofing!
We work directly with you to ensure clarity and precision in our quotes and services.
Throughout the process, we treat your home with respect, using drop cloths or tape as needed to protect surfaces, and working carefully to avoid mess.
The entire resealing procedure for a standard bathroom can usually be completed in just a few hours (plus curing time), meaning minimal disruption to your routine. You’ll be left with a freshly resealed bathroom that not only looks revitalized, but is properly protected against leaks.
Signs You Need Bathroom Resealing
| Sign | Description |
| Cracked, Peeling, or Missing Sealant | Inspect the silicone around your shower screens, bathtub edges, sinks, and toilet bases. Sealant that is cracked, peeling away, or partially missing indicates compromised seals. These gaps allow water to seep through, making resealing necessary. |
| Mould and Mildew Growth | Black or pink mould along silicone or in tile corners indicates trapped moisture and exhausted anti-mould properties in the existing sealant. Simply cleaning isn’t enough—removal and resealing with mould-resistant silicone is needed to permanently address this issue. |
| Water Leaks or Pooling Water | Noticeable water pooling outside showers or baths, or water stains appearing on ceilings or floors below bathrooms in multi-storey homes suggest failing seals. Professionally resealing these joints and edges typically resolves such leaks promptly. |
| Damaged Paint or Wall Plaster | Bubbling, peeling paint or swollen and cracked plaster near your bathroom fixtures may indicate moisture intrusion through failing seals. A musty smell accompanying these symptoms strongly suggests resealing is necessary to prevent further damage. |
| Loose or Shifting Tiles | Tiles coming loose in showers or around tubs often result from water infiltration caused by poor sealing. Immediate resealing helps prevent further tile damage or the need for extensive retiling. |
| It’s Been Many Years Since Last Sealing | Sealants generally degrade after 5-10 years due to continuous water exposure, cleaning chemicals, and temperature fluctuations. If it’s been a decade or you can’t recall your last resealing, it’s a proactive measure to have your bathroom resealed to prevent leaks and damage. |
| Recent Bathroom Renovation or Repairs | Any recent renovations, such as installing new shower screens, taps, or fixtures, could have disrupted your bathroom’s sealing. It’s important to reseal after these works to ensure your new or updated bathroom remains protected and watertight. |
If you notice any of these signs, it may be time for re sealing leaking showers to prevent further damage.
If you notice any of these warning signs, don’t wait until a minor leak becomes a major issue. Bathroom resealing is a quick, effective fix that can save your bathroom from extensive damage. We’re happy to inspect your seals and give an honest assessment.
Often, homeowners are surprised at the difference fresh sealing can make, both in looks and performance.
How do I know if my bathroom needs to be resealed or regrouted?
How do I know if my bathroom needs to be resealed or regrouted?
Resealing typically refers to replacing the silicone sealant around joints (like where the wall meets the tub or shower edges), whereas regrouting involves replacing the grout between tiles. If you’re seeing leaks at edges or mouldy, peeling silicone, then resealing is the solution. If the grout lines between tiles are cracked or falling out, regrouting might be needed. Often, a leaking shower might need both regrouting and resealing. Our experts will assess your bathroom and let you know what’s required – we can do minor regrouting in the corners if needed when we reseal. For many common leaks, simply resealing the perimeter and corners will do the trick.

New sealant sticks best to clean surfaces; if you put new silicone on top of old, the bond may be weak and the mould underneath can still spread. As professionals, we will remove the old degraded sealant completely before applying new silicone. While DIY kits exist, achieving a long-lasting, neat result can be tricky without experience. A poor seal job might only last a short time before leaking again. Hiring a professional ensures the old seal is properly removed and the new seal is applied correctly for a watertight finish you can trust.
How long does bathroom resealing take and when can I use my shower again?
How long does bathroom resealing take and when can I use my shower again?
The active work of removing old sealant and applying new usually takes only a couple of hours for an average bathroom. Once we’re done, we typically advise waiting about 24 hours to allow the new silicone to fully cure (dry and set) before using the shower or bath. This cure time ensures the sealant achieves its full strength and waterproof capability. In some cases, if we use fast-curing products, the wait might be shorter – we will let you know. We always aim to schedule work at a convenient time so the curing period causes as little inconvenience as possible (for example, resealing in the morning so you can use the shower the next day).
Do you offer any warranty or guarantee on your resealing work?
Do you offer any warranty or guarantee on your resealing work?
Yes, we stand behind the quality of our workmanship and materials. Canberra Plumbing offers a guarantee on our bathroom resealing – if the seal we applied fails due to workmanship within a specified period (we’ll detail this in your quote, often 12 months), we’ll return to fix it free of charge. That said, our use of premium sealants and proper technique means your new seals should last many years if cared for properly. It’s also important to note that if a leak persists after resealing, it could indicate a deeper issue (like a plumbing leak or failed waterproofing membrane) which we would have alerted you to. In such cases, additional work might be needed outside the scope of a standard reseal. But for the resealing itself, you can have peace of mind with our service guarantee.
Will resealing fix a leaking shower base or do I need a whole bathroom renovation?
Will resealing fix a leaking shower base or do I need a whole bathroom renovation?
Resealing is a targeted, cost-effective solution for leaks that originate from failing seals or grout in the shower area. In most cases of a minor leaking shower, resealing the shower tray edges and corners (and sometimes regrouting where needed) will stop the leak effectively. It saves you from undertaking a full renovation. However, if the leak is due to a compromised waterproofing membrane behind the tiles or a cracked shower base, the fix might be more involved than just resealing. Our plumber can usually tell during the inspection if the issue goes beyond old sealant. We believe in honesty – if resealing will not solve your problem, we’ll tell you and can discuss other repair options. But often, especially in showers that are a few years old, refreshing the seals does the job and extends the life of your bathroom for several more years without needing overhaul.
