Suggested reads about Waterproofing

What do waterproofing contractors offer?

Water issues can come from many sources. Areas like bathrooms that are commonly wet are the most prone, but you can also be a victim of water damage through burst pipes, leaky roofs or torrential rain. 

Waterproofing contractors and some local handymen offer professional services to protect your property from water damage. They specialise in waterproofing solutions, such as assessing vulnerabilities, applying waterproofing materials, conducting repairs, and ensuring a watertight seal. Trustworthy waterproofing contractors near you provide expertise to safeguard your home or building from potential water-related issues.

Bathroom waterproofing

Waterproofing contractors or bathroom tiling specialists can help seal your bathroom when building a new one or renovating your old space, as well as leaking showers. Bathroom waterproofers can waterproof your bathroom flooring and walls should you need to reseal your bathroom after its construction. 

Roof waterproofing

Waterproofing your roof is vital to keep your property’s or roofing membranes’ structural integrity intact. Roof waterproofing specialists identify areas prone to leaks, apply roof waterproofing membranes or coatings, repair existing damage, and ensure a watertight seal. Hiring a pro to waterproof your roof enhances roof durability and avoids water-related issues.

Wall waterproofing

A burst pipe, rising dampness or mould growth can cause problems in your home. Wall waterproofing is one of the steps to repair the damage on your interior walls or retaining walls and avoid the same case in the future. When looking for waterproofing near you, look for wall painting experts or local tradies experienced in wall waterproofing. They can come by, repair the damage and give your walls a fresh new look. 

Floor and tile waterproofing

A tiler can remove tiles, clean up your grout and set your new tiles. Their waterproofing service can come as an add-on cost. Ask your tile and floor waterproofers if they also do tile cleaning and sealing, so you can hire a professional that offers the services you require for a complete job. Consider concrete waterproofing contractors near you as well, as they can safeguard your driveways and footpaths.

Shower waterproofing

$200

Clovelly NSW, Australia

I’ve had water leaking into carpet outside my ensuite which I believe is due to failed waterproofing in the shower recess

Waterproof en-suite shower drain on second level of semi

$139

North Bondi NSW, Australia

18th May 2025

I need my en-suite shower drain waterproofed. The en-suite is on the second level of a semi and there is a small drip going to the ground level roof. I’ve run some tests and know the waterproofing issue is occurring in the shower strip drain of the en-suite above (by using a bucket and pouring water only into the drain strip insert). I don’t think it’s the pipe in the drain. The metal drain insert also seems loose when pressing on it. Attached are photos incl. the space between the downstairs ceiling and the above en-suite floor where the drip can be seen (taken by putting phone through recessed lighting on ground floor). It looks like the prior owners have previously done a dodgy job of trying to waterproof from ground floor using silicon so I am looking to get this fixed properly. Would like this fixed on a Wednesday, Thursday, Saturday or Sunday. Flexible with time of day. Thanks Rory Update: Unfortunately I don’t have any spare tiles, if tiles need be taken up and replaced.

Licensed Plumber Needed – Internal Shower Wall Leak & Waterproofing

$20

Kensington, New South Wales

1st May 2025

We need a licensed plumber to assess and repair a leaking shower in our Kensington unit. Strata has already arranged a plumber to test the shower tray and pipework—both passed with no leaks. However, the internal shower walls have been flagged as original and the waterproofing has failed, causing water damage to the opposite wall (bubbling paint, photos attached). We need: • On-site inspection of internal shower wall • Removal of wall lining as needed • Re-waterproofing and repair of affected wall areas • Advice on any tiling or follow-up work required This is owner-responsibility work (not covered by strata), so we are seeking a reliable and experienced plumber to carry out the job.

Came in, was very detailed, gave great advice and options on ways forward

Kitchen waterproofing issue

$5

Bellevue Hill NSW 2023, Australia

20th Sep 2021

I am unsure of the cost for this job so am open to quotes There is water / waste leaking into the B1 Car Park Our plumbers have identified that the leak is coming from around the floor waste in our kitchen area. See photos. On inspection it has been noted that there are a large amount of tiles in your kitchen area that appear to be missing grout between the tiles. This is the most likely cause, as it is allowing the water to penetrate below the drainage point and then passing though the slab penetration around the drain and leaking into the car park. The other concern is that the waterproof membrane that would normally be installed under the tiles and around the penetrations for drainage, may have been compromised. Can you please have your contractors look into this and carry out the necessary repairs as a matter of urgency.
