Who we are

A licensed plumber who specialises in water

Seaside is run by Sean, who has been a licensed plumber in Perth's northern suburbs for over 25 years and now specialises in whole-house water filtration. After seeing the impact of poor water quality on Perth families, and being frustrated by industry practices that put profit before people, he's dedicated to honest, affordable water filtration for the Perth community.

We tackle Perth's water challenges, like hardness, taste and quality, with whole-house and under-sink filtration and water softeners. And we're still your local plumber for hot water upgrades, burst pipe repairs, leak detection and general maintenance.

We pride ourselves on friendly, reliable service, using only premium products to ensure lasting results.

Jobs we're proud of

Filmed with Scott, two months after his install
In a customer's words

“He was so easy to deal with”

We asked Scott, a customer, how his whole-house system was going two months after we installed it, and what he'd tell a friend weighing us up against the bigger companies.

  • We've had it two months now on the system and it's great.

  • He was so easy to deal with. He'd come out and done a professional job.

Quotes are Scott's own words from the video.
