01 — About us
Adelaide-built. Trusted across every state we service.
A South Australian company that grew nationally without losing the accountability of an owner-run business.
THNZL Services started in Adelaide and has spent the last five-plus years earning the kind of trust that gets a cleaning crew a permanent set of keys. We work with banks, universities, government offices and national retailers — sites where a missed corner isn't an option, and where the same crew needs to turn up, on schedule, every time.
We're not a franchise dialling in from interstate. We grew a nationwide network of vetted cleaners from an Adelaide base without losing the accountability of a local, owner-run business. Every site gets a named point of contact, a documented scope, and a standard we hold ourselves to whether it's a single office or a multi-site rollout.
We also own our fleet — carpet extractors, upholstery steam units, pressure washers, floor scrubbers and industrial vacuums — so a job is never held up waiting on hired gear. Same machines, same crews, every visit.
Consistent crews, our own equipment fleet, transparent contractor compliance, and a company that answers the phone — not a call centre.

What sites actually notice.
Not promises — the operational details that make a contract easy to keep.
Same crew, every visit
We don't rotate strangers through your building. Cleaners are vetted and assigned to a site, so the people who know your floor plan are the ones who keep coming back.
Compliant contractor agreements
Every cleaner works under a documented arrangement built to meet Australian fair work standards, so your site isn't carrying sham-contracting risk on someone else's behalf.
We own our equipment
Carpet extractors, ride-on scrubbers, pressure washers and steam units are all ours. No job waits on a hire depot, and the machine that worked last month works this month.
Considered product choices
We pick products on effectiveness and impact, and we'll happily change the chemistry for childcare, healthcare or food-handling areas where it matters.
Nationwide reach, Adelaide roots
Grown from an Adelaide base into a network covering sites across Australia — multi-state contracts still get one client manager and one phone number.
Clear scope, clear cost
The quote sets out exactly what's included before anyone starts. No hidden fees, no line items that appear on the invoice for the first time.

See detailsResidential
Houses and apartments — regular home cleaning alongside our commercial contract work.
Our machines
Every job runs on our own equipment.
No hired gear, no delays — our crews bring a full owned fleet to every site.
- Hot-water carpet extractors
- Walk-behind and ride-on floor scrubbers
- High-pressure washers
- Upholstery steam cleaners
- Vehicle interior steam units
- Industrial wet and dry vacuums
- Water-fed window cleaning poles
- Rotary floor machines and buffers
Quality shouldn't depend on what the hire shop had left on a Friday afternoon. Our crews bring the same maintained machines to every job, and the people using them are the people who service them.
Why it's worth it
What a properly cleaned site gives you back.
First impressions
A clean site tells visitors, staff and clients your standards are high before anyone has said a word.
Staff morale
Less dust, clutter and grime means fewer sick days and a workspace people are happier to walk into.
WHS compliance
Regular cleaning reduces the slip, contamination and hygiene risks that sit under your site's WHS obligations.
Time and cost savings
No in-house cleaning staff to roster and manage, no machines to buy, service or store — we bring both.
Asset longevity
Consistent care extends the life of carpets, hard floors and furniture, pushing out replacement costs by years.
How it works
From enquiry to first clean.
Five steps, no mystery. You know what happens next at every stage.
Request a quote

Scheduled cleaning
Your assigned crew starts on the agreed date and keeps the same faces on the roster.
Quality check-in
Your client manager reviews the site with you and adjusts the scope as the building changes.
FAQs
Common questions.
Why choose THNZL over a cheaper cleaner?
A lower quote usually hides something — a rotating workforce, no insurance, or no compliance paperwork behind the contractors on your site. THNZL runs on vetted cleaners with documented, fair-work-compliant agreements and our own equipment. You are paying for the part of the job you can't see from the invoice.
Do you bring your own equipment?
Yes. We own our full fleet — carpet extractors, ride-on and walk-behind scrubbers, pressure washers, steam units and industrial vacuums. Nothing is hired, so no job is ever delayed waiting on a depot and the machines are maintained by the people who use them.
How much does commercial cleaning cost?
It depends on floor area, cleaning frequency and which services you need. We scope every site individually and quote a fixed, itemised price — there are no hidden extras and no surprise line items later. Most quotes go out within one business day of the site walk.
How long does a clean take?
A small office might be 60–90 minutes a visit; a multi-storey tenancy or a post-construction clean runs to days. We work that out at the site assessment and schedule it so it doesn't cut across your trading or business hours.
Can you service sites outside Adelaide?
Yes. THNZL is Adelaide-based, and our cleaner network covers sites across Australia. Multi-state contracts still get one client manager as a single point of contact rather than a different local operator in each city.
Are your cleaners insured and police-checked?
We carry public liability insurance, and police-checked crews are available for sites that require them — government tenancies, schools and banking environments in particular. We can supply current documentation with the quote.
