Your cleaner keeps missing things. Fix it, or change them.

Diagnose before you replace. Most failing cleaning contracts fail for one of four reasons — no written scope, staff turnover without handover, a price that never covered the work, or nobody auditing — and three of the four are fixable in about four weeks. Replace the contractor when there is no scope to enforce, when issues go to a call centre instead of a named person, or when the same failures recur after a documented corrective action.

Written scope and a fixed monthly price within 48 hours — useful even if you're only benchmarking.

First, work out which of the four problems you actually have

Replacing a contractor without diagnosing the failure usually reproduces it. The new contractor inherits the same undefined scope, the same access constraints and the same price, and month four arrives again.

Nearly every underperforming contract traces to one of these.

1. No written scope Nobody can say what was agreed, so nobody can say what was missed. Symptom: disagreements about whether a task was ever included. This is the most common cause and the most fixable.
2. Turnover without handover The inducted crew left; the replacement started with no walk-through. Symptom: quality dropped in a specific week, not gradually. Classic month-four failure.
3. The price never covered the work The quote won on price and the hours were never there. Symptom: the crew is visibly rushing, or leaves far earlier than the scope implies. This one rarely recovers.
4. Nobody is auditing The scope exists but sits in a drawer. Symptom: slow, unnoticed drift — tasks quietly stop and nobody can date when.

The four-week fix

If you have diagnosed problems 1, 2 or 4, this recovers most contracts. It also builds the documented record you will need if it does not.

Do it in writing throughout. A contract you fix this way ends up better documented than a new one signed in a hurry.

Week 1 — put it in writing Send a written list of the specific failures, with dates and photographs, referenced against the scope where one exists. Ask for a written response with a corrective action and a date. Set a review meeting for week four.
Week 1 — walk the site together Walk it with the account manager and, critically, the actual crew. Most "missed" tasks turn out to be tasks the current crew was never shown. An hour on site fixes more than a month of emails.
Week 2 — write or rewrite the scope If there is no scope, build one now — task, area, frequency, standard. If there is one, correct the rows that reality has moved past. Make it an annexure both parties sign.
Weeks 2–4 — audit weekly Score the scope line by line once a week and send the result. Weekly auditing changes behaviour faster than any conversation, because the crew can see exactly what is being measured.
Week 4 — decide If the failures have stopped, drop to quarterly audits and keep the contract. If the same items are still failing after a documented corrective action, you now have grounds and a paper trail. Move.

When to stop trying and replace

Some contracts are not recoverable, and continuing to work them costs you more in management time than the change would.

Any two of these together is enough.

No named contact Issues go to a call centre or a generic inbox. Nobody owns your site, so nobody can fix it — the structure is the problem, not the effort.
Crew changes constantly New faces every few weeks means every week is week one. No handover process will out-run that rate of turnover.
Repeat failures after corrective action The same items failing after a documented fix means capacity, not attention. A contractor who cannot fix it in one audit cycle will not fix it in three.
Compliance documents are slow to appear If certificates of currency, SWMS or training records take more than a day to produce, they may not exist. That is a liability sitting on your site.
The price is implausible A rate well below loaded employment cost means someone is being underpaid or is uninsured. That does not improve; it only becomes your problem later.

Exiting cleanly

Read the termination clause before you have the conversation, not after. Three things decide how simple the exit is.

Notice period and method Usually 30 to 90 days. Check how notice must be delivered — written notice to the address in the contract, not just an email to your account manager.
Rollover dates Many contracts auto-renew on an anniversary. Missing that date by a week can cost you another twelve months.
Assets on site Machinery, consumable stock, dispensers, keys, swipe cards and alarm codes. Agree in writing what is returned, what is reimbursed and when — dispensers are the item most often disputed.
Records Ask for the SDS register and any site-specific documents. They belong to the site and the incoming contractor will need them.

Changing over without a gap

The single most useful move in a contractor change: sign the incoming contractor before you serve notice on the outgoing one.

That gives the new crew time to walk the site, take keys and alarm codes, complete inductions and read the scope while the building is still being serviced. A week of overlap costs one week of double service and removes every version of the failure mode where a building goes unserviced, a key goes missing, or an alarm code is never handed over.

Step 1 Get the incoming contractor to walk the site and quote against your scope — the one you now have in writing.
Step 2 Sign, and agree a start date at least a week before the outgoing contract ends.
Step 3 Serve notice on the outgoing contractor, in the manner the contract requires.
Step 4 Run the overlap week: new crew inducted and shadowing, keys and codes transferred, dispensers and stock reconciled.
Step 5 Audit the new contract in month one against the scope. The point of the change was a document you can enforce — enforce it from the start.
The short version
01

Four causes: no written scope, turnover without handover, a price that never covered the work, nobody auditing. Three are fixable.

02

Complain in writing against the scope with dates and photographs. Verbal complaints to a cleaner on site are not a record.

03

Replace when there is no named contact, constant crew turnover, or repeat failures after a documented corrective action.

04

Sign the incoming contractor before serving notice. A one-week overlap removes every gap-in-service risk.

Questions

Changing contractor, answered.

Or just call 1300 168 057.

Why does commercial cleaning quality drop after a few months?

Almost always staff turnover without handover. The crew that was inducted to your site leaves, a replacement starts with no written scope and no walk-through, and they clean what looks obvious rather than what was agreed. Quality doesn't decay gradually — it drops the week the crew changes, which is why month four is the classic failure point.

How do I complain to a cleaning company effectively?

In writing, against the scope, with dates and photographs. Reference the specific task and frequency line that was missed rather than describing a general standard, name the dates it was missed, and ask for a written response with a corrective action and a date. A verbal complaint to a cleaner on site is not a record and won't support termination later.

How much notice do I need to end a commercial cleaning contract?

Usually 30 to 90 days, set by the termination clause. Check three things before serving notice: the notice period and how notice must be delivered, whether there's an automatic rollover date approaching, and whether equipment, consumable stock or keys need to be returned or reimbursed. Serve notice in writing to the address in the contract, not by email to your account manager alone.

How do I change cleaning contractors without a gap in service?

Overlap them. Sign the incoming contractor before serving notice on the outgoing one, so the new crew can walk the site, take keys and alarm codes, and be inducted while the old contract still runs. A one-week overlap costs one week of double service and removes every risk of an unserviced building, missing keys or an unreturned alarm code.

Should I fix the current cleaning contract or replace it?

Fix it if there's a written scope, a named contact who responds, and the failures started recently — those are usually a handover problem and are correctable in four weeks. Replace it if there's no written scope, issues go to a call centre, the crew changes constantly, or the same failures recur after a documented corrective action. A contractor who can't fix a problem in one audit cycle won't fix it in three.
