A leaking shower doesn’t always mean tiles need to come out. Cracked or peeling silicone, gaps around the shower base, persistent mould, or dampness outside the enclosure can point to water escaping through worn seals. Shower resealing in Perth may help when failed silicone is allowing water through a joint.It’s understandable to worry that a leak means a major renovation. If the leak is coming from a sealed joint, carefully removing the old silicone and applying fresh sealant may address it without removing tiles.This guide covers the signs to look for, how old silicone is removed and replaced, and when resealing may not be enough. You’ll also learn what affects the work involved and how professional shower and tile restoration can help care for your bathroom surfaces.

What Are the Signs of a Leaking Shower?
Watch for water beyond the shower screen, swollen skirting, peeling paint, or damp carpet beside the bathroom. Inside the enclosure, check silicone joints and grout for cracks, gaps, dark staining, or sections pulling away. These signs may indicate a leak, but plumbing faults or water escaping elsewhere can cause similar damage.After showering, dry the floor outside the enclosure and check for fresh moisture near the doorway or adjoining wall. Persistent mould in a corner, a musty smell, or staining on the ceiling below can also signal water damage. A balcony leak can cause similar ceiling marks, so the location alone doesn’t identify the source.Surface repairs suit failed sealant or localised grout damage. A split silicone bead at the base may need resealing, while crumbling grout across several joints may call for regrouting. If water continues escaping after repairs, or the waterproofing membrane or plumbing appears faulty, surface work won’t fix the cause. The underlying issue needs assessment by the relevant specialist.How can I tell if a shower needs resealing or full regrouting? A loose or cracked silicone joint with sound grout points towards resealing. Widespread crumbling, missing grout, or open joints across the tiled area suggests regrouting may be needed.Are there local building or waterproofing rules relevant to shower repairs in Western Australia? Surface resealing and grout repairs don’t replace a waterproofing membrane. If the membrane or building work is involved, the applicable Western Australian requirements must be considered for that work.Repair pricing depends on the case and is provided after a quote request; the affected area, access, grout condition, and whether the repair covers a shower base or the full shower influence the work. A warranty describes the work it covers, so review its terms alongside the repair scope.After repairs are completed, keep the shower unused for at least 48 hours. This allows the repaired area to cure before water reaches the new sealant or grout, helping protect the finish and limit further leaks.How do you reseal a shower?
Shower resealing addresses failed silicone at joints, while regrouting renews deteriorated grout between tiles. The right approach depends on where the seal has failed and how widely the grout is damaged.Resealing and Regrouting Services
A reseal generally involves removing old silicone, preparing the joint, then applying fresh sealant. For softened silicone, allow the remover to work for a few hours before scraping away residue. Regrouting is different: it renews grout in affected joints rather than sealing the edges. In Perth bathrooms, inspect the floor-to-wall junction, corners, and screen edges to identify the work needed.Ask for the scope to distinguish silicone replacement from grout repairs. A clear description should identify the affected joints, preparation, and finish. Sealant life depends on use, ventilation, cleaning, and the condition of the joint. A main family bathroom may warrant repair sealing every six months, while a guest bathroom may need it every two years.Choosing a Reliable Contractor
When arranging shower repairs in Perth, compare written scopes, preparation steps, product details, and workmanship terms. A clear quote explains whether it covers resealing, regrouting, or both, and identifies areas excluded from the work. It should describe how the repair addresses the visible cause, rather than relying on a broad promise of satisfaction.For a home in Perth or Fremantle, check that the quoted service area includes the property and that its booking hours suit your schedule. Warranty and guarantee terms vary; read the written coverage, exclusions, and duration before accepting the work. No single warranty term applies to every repair.Do Perth shower resealing contractors offer warranties or guarantees? Terms differ between contractors and jobs. Review the written workmanship coverage and its exclusions, rather than assuming a guarantee covers every cause of a leak.Service prices depend on the affected area, access, and whether the job involves the shower base or full-shower regrouting. The price is provided after a quote request, not as a universal rate. The repair method and scope also determine when the bathroom can return to use; allow the sealant or grout to cure as directed before exposing it to water.Signs of a leaking shower
A leaking shower can show signs inside the enclosure and in adjoining rooms. Inspect the shower recess, nearby walls, and floor after use, noting where moisture appears and whether it returns.Moisture Damage Indicators
Look beyond the tiles. Bubbling paint, lifting skirting, swollen door trim, or a musty smell near the bathroom can indicate moisture behind finished surfaces. In a multi-storey home, staining on the ceiling below the bathroom is another warning. Note where and when it appears; repeated dampness after shower use can help narrow down the source.Check grout lines and silicone closely, especially where the shower floor meets the wall. Darkened or persistently damp grout, a loose tile, or a visible gap can indicate water is travelling past the surface. Don’t assume a stain proves the shower is leaking; note its position and compare it with the wet area after use.Common Leak Causes and Warnings
Cracked grout, separated silicone, and unsealed cement-based grout can leave routes for water through tiled surfaces. In Perth, homes built between the 1980s and 2000s may have cement-based grout that wasn’t sealed properly. That history makes careful inspection useful, but age alone doesn’t establish the cause of a leak.Look for movement at corners, gaps around screen fittings, or silicone pulling away from a joint. These defects may let water escape during normal shower use. Removing failed silicone can reveal a gap beneath, but it won’t show whether the waterproofing membrane is intact. A surface repair can’t restore a damaged membrane.To keep a useful record, photograph each affected joint and note the damp area’s location. Record whether moisture appears only after showering or remains between uses. Compare the shower recess with the adjoining wall and floor, then check whether the signs are spreading. These details help distinguish a localised seal failure from broader moisture damage and guide the next repair assessment.Removing old silicone and applying new sealant
A durable reseal starts with complete removal of failed silicone. Applying a fresh bead over old material can leave gaps, trap moisture, and weaken adhesion. Inspect the full joint, including corners, screen edges, and the shower base, before deciding whether resealing can address the leak.For silicone removal, work carefully along the bead with a suitable scraper, avoiding damage to tiles and fittings. A silicone softening agent can help loosen stubborn residue; leave it to work for a few hours before scraping. Remove remaining traces, then clean the joint and let it dry thoroughly. New sealant won’t bond reliably to a damp or contaminated surface.Apply the sealant as a continuous bead, keeping it even through corners and changes of direction. Smooth it so it contacts both sides of the joint, with no visible gaps or pinholes. Preparation is essential: sealing over residue or moisture can undermine the finish before the shower is used again.After application, follow the sealant’s curing instructions and keep water away from the repaired area. Don’t assume the same waiting period applies to every product or joint. Follow the product’s stated cure time to determine when shower use can resume. This helps protect the new seal and prevent moisture from entering the joint.Fresh silicone only addresses the joint it seals. It doesn’t repair damaged grout, plumbing faults, or a failed waterproofing membrane. If an inspection finds ongoing dampness behind the tiles, the cause needs investigation beyond surface sealing. A clear repair scope should identify the joints being treated and distinguish resealing from work on other causes.For shower resealing in Perth, choose careful removal, a clean and dry joint, continuous application, and proper curing.

Does it cost anything to get a quote?
Ask for a quote before approving any work, and review its scope and charges before proceeding. A quote request gives the trade professional the details needed to assess the shower and outline the proposed work. Include clear photos of the affected area, whether the issue is at the base or walls, and any previous repairs. This helps make the scope more specific.How much does it cost to fix a leaky shower in Perth?
The cost depends on the cause and extent of the leak, and is provided after a quote request. A localised seal failure differs from widespread grout deterioration or a problem involving plumbing or waterproofing. Access and the areas needing repair also affect the scope. A written quote should distinguish surface work from repairs addressing other causes, so you can understand what the proposed amount covers.What does shower resealing involve in Perth?
Shower resealing in Perth generally focuses on renewing failed sealant at joints, such as where the shower base meets tiled walls. The work involves removing old silicone, preparing the joint, and applying fresh sealant. It suits leaks travelling through a failed sealed joint, rather than a plumbing fault or damaged waterproofing membrane. The scope should identify which joints are included.How much does shower resealing cost in Perth?
The price depends on the repair scope and is given after a quote request. Relevant factors include the length and condition of the joints, access to the shower, and the preparation required before new sealant can be applied. A small section of failed silicone differs from several affected edges. Check that the quote describes the areas being resealed and any additional work.What is the average cost per metre to reseal a shower in Perth?
A per-metre figure alone may not reflect the full work involved, because preparation and access matter as well as joint length. Each shower has a different scope. For a useful comparison, review which joints are included and whether removing old silicone and preparing the surface are part of the work.How long does shower resealing take and how soon can the shower be used?
The resealing duration depends on the amount of silicone to remove, joint preparation, and the area being treated. Regrouting takes longer: a shower-base regrout typically takes 2-3 hours, while a full-shower regrout typically takes 6-10 hours. After repairs are completed, keep the shower unused for at least 48 hours before using it again.
