What we do
Plumbing & gas, sorted properly
Residential and light commercial across the Sunshine Coast. If it carries water or gas, we handle it — and we quote the price before we pick up a tool.
24/7 Emergency
Burst pipes, major leaks, no hot water, blocked toilets — day or night, we answer.
Call anytime
Blocked drains
CCTV camera inspection to find the blockage, then cleared properly — not a quick flush.
Hot water systems
Repairs, replacements and upgrades — gas, electric, heat pump and solar.
Gas fitting
Licensed gas work: appliance connections, cooktops, leak checks and compliance.
Leak detection
Find hidden leaks before they wreck your floors or blow out your water bill.
Taps & toilets
Dripping taps, running toilets and worn fittings sorted in a single visit.
Bathroom renos
Full plumbing rough-in and fit-off for your bathroom or laundry renovation.
Backflow testing
Certified annual testing and reporting to keep your property compliant.
About Coastline
Fifteen years on the Coast — and we still answer the phone.
Dave Mercer started Coastline Plumbing & Gas in Kunda Park back in 2011. Today it's still a family-run team of licensed tradesmen who treat your home like their own — boots off at the door, drop sheets down, and cleaned up before we leave.
No apprentices sent out to figure it out on your job. No vague hourly rates that balloon by the afternoon. Just honest, licensed work at a price we agree before we start.
The on-time guarantee
We give you a real arrival window and stick to it. Running late? You'll get a call — you won't be left waiting around all day.
Where we work
Covering the whole Sunshine Coast
Based in Kunda Park, on the road across the Coast and hinterland every day.
