Frequently asked questions
What does your plumbing licence cover?
Our plumbing licence covers water supply, sanitary, drainage, gasfitting, backflow prevention, roofing (stormwater) and fire protection for hydrants.
Do you work outside business hours?
Our hours are Monday to Friday, 7am to 5pm. Outside them we attend burst fire services and major water leaks, look after our existing commercial clients, and schedule work outside normal hours where a site needs it. We are not a general after-hours domestic plumbing service.
What do you supply before work starts?
Certificates of currency, safe work method statements, site inductions and any project-specific safety documentation. Compliance certificates follow on completion.
Do you find the cause before you repair?
Yes. We look at why a fault happened and whether something else is likely to cause trouble, document what we find, and give you the options before we repair.
Can we see your capability statement?
It is available on request. Ask for it in your enquiry and we will send it through.
