Project types we support

• New residential builds
• Home extensions and second-storey additions
• Major renovations where wet areas or kitchens are reconfigured
• Select light commercial fit-outs and small commercial builds (see also commercial plumbing)
• High-spec residential work where finishes demand precise set-outs

Owner-operated since 2017, we are sized for builders and owner-builders who want a licensed plumber that answers the phone, reads the drawings, and shows up for the booked stage — not a revolving subcontract roster.

Rough-in: getting the bones right

Rough-in is where construction plumbing earns its keep. Supplies, stacks, vents and fixture points are set before linings conceal mistakes. We work from architectural and hydraulic drawings where provided, or from a coordinated site mark-up with your builder.

• Hot and cold water reticulation sized for the fixture load
• Soil, waste and vent pipework with correct falls and supports
• Bathroom and kitchen points set to cabinet and tapware specifications
• Laundry, dishwasher and fridge points where the design requires them
• External taps and meter arrangements as documented

For wet-area-heavy renovations, our bathroom plumbing detail work sits inside the same construction sequence — one team, consistent set-out language.

Drainage and stormwater on site

Buildings fail inspections when drainage is an afterthought. We install and connect sanitary drainage to design and coordinate stormwater pathways so downpipes and in-ground drains are not competing for the same trench on handover day.

Where the project includes new pits, grated drains or altered roof catchment, our stormwater drainage capability covers design-aware install and repair — keeping surface water away from footings and paved areas around builds in suburbs such as Norwood and Paradise.

Gas and hot water during construction

Modern builds often lock in gas cooking, ducted heating feeds, bayonet points and continuous-flow or storage hot water early. We run and pressure-test new gas lines, connect appliances at the right stage, and provide compliance certificates for gas work performed.

• Licensed gas fitting for LPG or natural gas as specified
• Hot water system installation sized to bedrooms and simultaneous-use expectations
• Flueing, drainage trays and tempering arrangements to code
• Coordination so heaters are not delivered months before a safe install window

Certificates and documentation are part of practical handover — owners and builders need them for records and, where relevant, occupancy processes.

Fit-off and practical completion

Fit-off turns a framed wet area into a working home. We return after painting and bench installation windows to fit tapware, toilets, basins and remaining fixtures, then test every outlet. Snag-list items get cleared promptly within Monday–Friday 7:30am–5:00pm so practical completion is not held on a dripping spout.

We protect finished surfaces, keep sites tidy, and communicate if a supplied tapware set is incomplete or incompatible with the rough-in — early, not on handover morning.

Working with builders: schedule and inspections

Construction plumbing succeeds when stages are booked against the program:

1. Pre-start review of drawings and fixture schedules
2. In-ground / under-slab drainage where applicable
3. First and second fix / rough-in before linings
4. Inspections as required for the project type
5. Gas and hot water plant install windows
6. Final fit-off and testing

We aim to pass inspection stages without avoidable delays — correct falls, supported pipework, accessible test points and documentation ready. If a design detail conflicts with code or practical service access, we raise it with the builder before it is buried.

Renovations vs new builds

New builds offer clean routes and predictable sequencing. Renovations and extensions — common across older eastern and inner-western housing stock, including projects near Torrensville — add live services, asbestos-era surprises (handled by the right licensed trades), and partial demolitions that must keep a bathroom working for the family upstairs.

We plan isolations carefully so occupants retain water where possible, and we stage work so temporary supplies and site amenities remain usable.

Information we need for an accurate quote

• Architectural plans and any hydraulic drawings
• Fixture and tapware schedules (or provisional allowances)
• Gas appliance list and meter / tank arrangements
• Hot water preference (gas, electric, heat pump, solar) and bedroom count
• Builder contact and target rough-in / fit-off dates
• Site address and access notes

Under-slab and in-ground stages

Where designs call for under-slab drainage or services in the ground before concrete, timing is unforgiving. We need clear levels, set-outs and inspection hold-points agreed with the builder. Rushing this stage to “keep the pour” is how defects get cast in place.

• Confirm datum and finished floor levels before pipework is fixed
• Protect open ends from debris during other trades’ work
• Photograph concealed joints where helpful for the project record
• Coordinate trenches with electrical and other services to avoid clashes

Quality expectations on a Streamline site

Construction clients remember the plumber who left penetrations labelled, capped lines cleanly, and did not bury a mystery join behind a stud. Our site habits include:

• Following the approved drawings — and raising RFIs when reality disagrees
• Supporting pipework to code rather than “it will be fine”
• Keeping amenities and site toilets working where we are responsible for them
• Communicating delays the same day, not the morning of an inspection

That professionalism matters as much on a dual-occupancy in the eastern foothills as on a single-storey extension behind an older villa.

Provisional sums and fixture allowances

When tapware is not yet selected, we can rough-in to agreed centres and depths based on provisional allowances — but late changes to wall-hung pans, progressive mixers or freestanding baths can force rework. Lock critical fixtures before second-fix where possible, or accept that variations will be quoted fairly when selections finally arrive.

Construction plumbing across Adelaide East, North-East and West

From Athelstone we support builds and extensions throughout our footprint. Check areas we serve or call with the site suburb to confirm coverage and travel for staged attendances. Call 0401 916 325 with your site address and target rough-in week if you need a rapid yes-or-no on coverage.

Variations, delays and how we handle them

Construction changes. A spa bath becomes a shower, a scullery appears late, or a heater moves to another wall. We price variations clearly and will not silently absorb scope that was never in the quote — nor will we hold a site to ransom over minor extras. Written variation notes keep builders, owners and accountants aligned.

If weather or other trades delay a booked rough-in, contact us as soon as the program slips. Rebooking within Monday–Friday 7:30am–5:00pm is far easier with two days’ notice than with a text at 6am on pour day.

We also flag long-lead items early: specialty tapware, certain continuous-flow heaters, and custom pan connectors can affect fit-off dates if ordered late.

Handover pack for owners

At the end of a construction plumbing package we can provide a simple handover summary: key isolation points, hot water type, gas certificate references for work we completed, and maintenance reminders. Owners appreciate knowing where the meter key lives and which valve shuts the upstairs bathrooms without killing the kitchen.

Based locally in Athelstone, we keep stage attendances efficient across East, North-East and West Adelaide — which helps builders running tight programs on neighbouring sites. If you have a dual-occupancy or back-to-back extension package, ask about aligned rough-in days to reduce scaffolding and access conflicts.

How to engage us on a build

1. Send plans and a brief scope to quote.
2. We review, ask clarifying questions, and provide clear pricing.
3. Book stage dates against your program; we attend, inspect-ready, within business hours.
