Mona Vale is the commercial centre of the Pittwater end of the Beaches, with a busy shopping strip, business park, apartments around the village and family homes stretching from the beach back toward the hills. Its drain problems are as varied as its buildings. Beaches Blocked Drains is a local referral service. We connect you with licensed local drain plumbers who service Mona Vale.
Why Mona Vale drains block
Beachside sand. Homes near Mona Vale Beach and Bongin Bongin Bay deal with sand in gullies, outdoor showers and stormwater pits, and in cracked pipes.
Older homes. Many original houses still run clay sewer lines. Roots from garden trees and Norfolk pines find the joints.
Apartments and shops. Unit blocks around the village share sewer stacks, and cafes and restaurants produce grease that builds up in lines and arrestors.
Low ground. Parts of Mona Vale are flat and close to the water table, so stormwater can struggle in heavy rain.
How it gets cleared
A CCTV drain camera identifies the cause, whether sand, roots, grease or a cracked pipe. Jet blasting clears all four types of blockage and is the standard approach for sand and grease. If the camera shows a damaged section, pipe relining can repair it without breaking up a driveway or courtyard.
What it costs in Mona Vale
A standard clear typically runs $150 to $400. A combined camera and jetting job typically runs $350 to $900. Root clearing typically runs $250 to $600. Commercial jobs are quoted for the site. You get the price before work starts.
If waste water is backing up, see emergency blocked drains.
Frequently asked questions
Can the plumbers you work with help with a cafe or shop drain?
Many do commercial work. Tell us the type of business and whether there is a grease arrestor when you enquire.
Why is my drain full of sand when I live a few streets back from the beach?
Wind-blown sand and sandy soil reach further than you might expect. If it is inside the pipe, a cracked joint is usually letting it in.
My unit's sink is blocked. Is it my cost?
If the blockage is in pipework serving only your unit, it is usually yours. If it is in a shared stack, it usually sits with the owners corporation.
