Seaford sits on the bay at the northern end of the city, with Kananook Creek running behind the coastal dune toward Frankston. Much of its housing went up in the 1950s and 1960s, and at the 2021 Census about 74% of homes were separate houses and about a third were rented. Frankston Blocked Drains is a free referral service connecting you with licensed drain plumbers who cover Seaford and the 3198 area. We are not a plumbing business, and the referral costs you nothing.
Postwar sewer lines
The older Seaford houses have sewer lines that are 60 years old or more, and with established trees around them, root intrusion at the joints is a common cause of slow drains and repeat blockages. Where blocks have since been redeveloped for units, the new buildings may connect into lines that are shared between lots, and a blockage there is one for the owners corporation to arrange.
Stormwater and heavy rain
VICSES notes that Seaford is prone to flash flooding during heavy rainfall, which can close roads and affect private property. In a big storm, water pooling in the yard may be the street drainage overwhelmed rather than a blockage on your land. Once the rain stops, check your own pits and downpipes. Near the coast, sand washing into stormwater pits is worth watching for. Your property's drainage links to Frankston City Council's network at a stormwater discharge point, which the council can locate on request. See blocked stormwater.
Rentals
About a third of Seaford homes are rented. Renters should tell the landlord or agent straight away, in writing. Landlords can send the quote form with the tenant's contact details and the plumber can arrange access.
What it typically costs
As a guide, a standard clear typically runs $150 to $400, a camera with jet blasting $350 to $900, and relining $3,000 to $8,000 and up. Quotes vary, the plumber's written quote is the price that counts, and confirm GST on it. See the cost guide.
Frequently asked questions
Why does my stormwater pit fill with sand?
Sand and soil wash in with heavy rain, particularly near the coast. Regular clearing and a pit cover help.
Where can I check flood information for my address?
Ask Melbourne Water, which manages the main drains and waterways, or Frankston City Council.
My unit shares a drain. Who pays?
A shared private line is usually a matter for the owners corporation. Start there.
