Builder pricing in Western Australia — FAQs

Do builders charge a call-out fee in Western Australia?

Many do—typically $60–$150 to assess the job. Some apply it toward the final quote if you hire them. Always ask upfront. Emergency or after-hours calls often carry a surcharge.

Should I get a fixed price or hourly rate?

Fixed-price suits defined jobs (renovations, fencing). Hourly rates work for repairs where scope is unclear. Always get a written quote with a not-to-exceed cap to avoid surprises.

How many quotes should I get?

Aim for 2–3 quotes from licensed builders. Compare scope, timelines and materials—not just price. Cheap isn't always better; check reviews on TopTradiesAustralia first.

Is GST included in quoted prices?

No—quotes typically exclude 10% GST. Always clarify whether the figure quoted is GST-inclusive or not. Licensed builders must register for GST if turnover exceeds the threshold.

What if the job goes over budget?

Changes to scope, site conditions or materials usually trigger variations. Get variations in writing before work starts. A good builder will flag risks early and agree on limits beforehand.
