Whatever the job, it's one phone call

A one-stop shop for plumbing and gasfitting — including caravans, motorhomes and tiny homes. One call, one team, and we certify our own work.

Site Safe accredited Self-certifying — drainage, drainlaying & gasfitting Caravans & tiny homes certified
01

Plumbing

Day-to-day plumbing for homes, farms and businesses. Most repairs are sorted in a single visit, and we'll tell you honestly if something is better replaced than patched.

  • Leaking and dripping taps
  • Burst and frozen pipes
  • Blocked toilets and sinks
  • Hot water cylinders
  • Bathroom and kitchen fit-outs
  • Water filters and pumps
  • Roof and spouting repairs
  • General maintenance
02

Gasfitting

Gas work is regulated for good reason. Ours is done by a qualified gasfitter and self-certified on the spot, so your insurance and compliance paperwork stack up without a council inspection holding things up.

  • LPG and natural gas
  • Califonts and gas hot water
  • Cooktops and ovens
  • Gas fires and heaters
  • Bottle installs and changeovers
  • Leak testing
  • Gas certification
  • Servicing and repairs
03

Drainlaying & excavation

We lay new drains and fix old ones, and we run our own digger — which means no waiting on a separate contractor and no finger-pointing if something goes sideways. We’re also self-certifying for drainage and drainlaying, so the sign-off doesn’t sit in a council queue.

  • New drainage for builds
  • Blocked and broken drains
  • Stormwater and soakpits
  • Septic tank connections
  • Trenching and site works
  • Water and waste lines
  • Council connections
  • Rural drainage

Septic systems

Out of town there's no main to connect to, so the septic system is the whole waste system — and if it's wrong you'll know about it. We install complete systems from scratch and replace tired ones: tank, field, pipework and sign-off.

We size the system to the house and the ground it's going into, dig it with our own digger, and being self-certifying for drainage and drainlaying means we issue the paperwork ourselves. One team from the first hole to the certificate.

  • New septic tank installation
  • Tank replacements and upgrades
  • Effluent and disposal fields
  • Soakpits and soil assessment
  • Pump-out and inspection points
  • Connections for new builds
  • Repairs to failing systems
  • Self-certified sign-off
05

New builds, renovations & commercial

From slab to sign-off. We work in with builders and project managers on residential and commercial jobs, keep to the programme, and leave the site tidy.

  • Full new-build plumbing
  • Bathroom renovations
  • Commercial fit-outs
  • Backflow prevention
  • Maintenance contracts
  • Compliance and certification
06

Caravans, motorhomes & tiny homes

We certify gas and plumbing in caravans, motorhomes and tiny homes — the certificates you need for a warrant, for your insurer, or to sell it on with everything in order. Being self-certifying means we can issue them ourselves, so you're not booking an inspector and waiting.

  • Gas certification
  • Plumbing certification
  • Bottle and appliance installs
  • Water and waste fit-out
  • Leak testing
  • Pre-sale sign-off
07

Fire installation

Winters down here are no joke. We install wood burners and gas fires, flues and wetbacks, and handle the consent side so you're not chasing council yourself.

  • Wood burner installation
  • Gas fires
  • Flues and hearths
  • Wetback connections
  • Consent paperwork
  • Replacements and upgrades
