Water can cause massive amounts of damage if allowed to leak throughout your home or business. Leaks can cause rotting wood, mould growth, rusting steel and other metals, delamination of materials like plywood and much, much more.

Water damage can be slow and appear in small dots around the affected area, or it can be rapid and catastrophic, causing major flooding and damage throughout the building. To help avoid water damage in your home or business, we recommend keeping on top of waterproofing.

That’s where we come in. At Newcastle Plumbing Service & Blocked Drain Specialist, we’ve been helping home and business owners throughout Newcastle, to waterproof their buildings for more than 40 years.

Over the years, Dave Levey and the team have developed a strong reputation as Newcastle’s waterproofing and plumbing experts. From waterproofing to roofing, hot water systems, blocked drains and more, we can handle all of your plumbing and home improvement needs in Newcastle.

Get in touch with our professional team of waterproofers and plumbers. We’d love to help improve the functionality of your home or business!


Looking for a team of plumbers and waterproofers in Newcastle to help with your new home build or renovations? Our team would love to help make your brand new home both comfortable and functional with effective waterproofing.

On average, waterproofing makes up around 2% of your total building costs. It’s a small price to pay for professional waterproofing and eliminating the risk of leaks and water damage down the line.

Just give us a call to discuss your waterproofing needs for your new home build. If you’re unsure what needs to be done, our team of waterproofers can come to the building site and determine what areas need waterproofing – for example, the tiles, the bathroom, shower, laundry, roofing, and even structures like decks, patios, and balconies.

It might come as a surprise, but insurance statistics have shown the highest number of waterproofing failures come from rooftops and balconies. It’s important to get a professional waterproofer in to highlight all areas of your new home which could be prone to leaks and water damage.

Along with plumbing and quality waterproofing, we’re Newcastle’s roofing and guttering specialists. Let us help make your dream home a reality!


The most common area that needs waterproofing is the bathroom. Due to amenities like showers, sinks, baths, and toilets, the risk of water damage is much higher in the bathroom than the rest of the house.

A lot of homeowners probably aren’t aware, but underneath the tiles in your bathroom there should be what’s called a “waterproof membrane”. This is a water-tight layer of material designed to stop water from leaking through into the walls and floors.

Unfortunately, waterproof membranes are prone to breaching and letting water trickle through the cracks. This can cause major water damage over time. Waterproof membrane breaches can be caused by your home or business settling into its foundations, movement, and even the use of cleaning chemicals in the bathroom.

Blocked drains can also cause a buildup of water and potential leaks. This affects the bathroom, kitchen, and even the laundry. These areas have sinks, dishwashers, washing machines, and more – all water-based amenities which can leak or malfunction from a blocked drain.

What kind of waterproofing services do you offer?

We offer general waterproofing repairs, bathroom waterproofing, balcony waterproofing, deck and patio waterproofing.

It depends how much waterproofing work needs to be done and whether it’s a complete waterproofing service or a simple repair. Make sure to get in touch with our team to discuss the problem at hand, or we’ll organise a time to visit your location and determine what work needs to be done.

Then, we’ll provide an obligation free quote so you can decide whether you want to go ahead with the job.

Again, it depends on the scale and nature of the waterproofing job at hand. However, our team has more than two decades of experience in plumbing and waterproofing, so we will get the job done as quickly and efficiently as possible so you can get back to your day.

It depends on what method we use to waterproof the area. However, you’ll need to wait until the waterproofing solution has dried completely before using the space.

Most of the time, a leak from a water membrane breach is slow and steady. However, in severe circumstances, it could cause major water damage and even flooding. In the event of a major water membrane breach, get in touch with our team immediately.

Through our emergency plumbing service, we can get the leak under control and prevent expensive water damage.

We offer a wide range of plumbing, gas fitting, and waterproofing services in Newcastle. Our services include:

We can also install, manage, and maintain your hot water system to ensure you have warm water at all times. There’s nothing worse than waking up to a cold shower!
