Supervising Subcontractors and Labour Agencies on Cleaning Contracts

Subcontracted labour is how most cleaning companies grow past the point where the owner can be on every site. It is also how a clean-looking operation quietly develops two standards: one for the crews the client sees every night, and one for the agency staff sent in when someone calls in sick.

The gap is rarely about effort. The gap is that nobody told the agency worker what the standard is, nobody checked the work against a written sheet, and nobody recorded the result. Fix those three things and subcontracted labour becomes an asset rather than a risk.

Key takeaways

• Decide before you hire whether you are buying hours or buying cleaning. The two need different contracts, supervision and pricing.
• Write the scope to the outcome. "Vacuum all traffic lanes" is auditable; "two hours of general cleaning" is not.
• Induct every agency worker on their first shift, on site, using the same checklist your own crews work from.
• Inspect subcontracted areas on the same schedule and the same score sheet as your own.
• Keep one evidence file per site: specification, coverage certificates, induction records, inspection scores, photos and closed deficiencies — critical
• Pay against inspection results, not attendance sheets.

Hours or outcome: the first decision

There are two commercial models for subcontracted labour, and mixing them causes most disputes.

Labour supply is fine when you genuinely only need bodies and you intend to supervise them yourself. It fails when you hand over an area, stop visiting, and rely on the agency to police its own quality. If you are not going to supervise it, buy it as a service with a specification and a score.

What has to be in the subcontract before the first shift

A subcontract is not a shortened version of your client contract. The clauses that matter are operational.

• Scope, area by area, with frequencies, attached as the same task list your own crew works from.
• The standard and how it is measured — name the score sheet, the scale and the inspection frequency.
• Proof of insurance and workers' compensation coverage, checked at signing, annually, and after any change of ownership — critical
• Who employs whom. State that the agency employs its workers and owns wages, deductions and statutory entitlements.
• Training and competency evidence for anything regulated: WHMIS, working at heights, chemical handling — critical
• Key, alarm code and access handling, including what happens when a worker leaves the agency — critical
• Rates, payment terms, the right to reduce payment against failed inspections, and the right to remove an individual from site.

Vague clauses get tested exactly once, on the night something goes wrong.

The induction that stops most problems

Most subcontracted labour failures trace back to a first shift where nobody explained anything. A ninety-minute site induction, delivered by your supervisor rather than emailed, prevents the majority of recurring findings.

1. Walk the building in the order the work happens, not the order the floors are numbered.
2. Hand over the written task list for the areas that worker will own.
3. Demonstrate the two or three tasks where technique changes the result: restroom sequence, floor care, glass.
4. Show the chemical store, the dilution station and the safety data sheets — critical
5. Cover the safety specifics of the building: loading, stairs, electrical rooms, anything out of scope — critical
6. Explain how the work will be checked, by whom, and what a failed inspection triggers.
7. Record date, attendance, topics and who delivered it, filed against the site — critical

When a client asks who cleaned their building last Tuesday and what they were told, the answer should be a document.

Evidencing subcontracted work

Evidence is where subcontracted labour is won or lost. If you cannot produce the same record for an agency-cleaned floor as for your own crew's floor, you have two standards whether you intended to or not.

An inspection record with a photograph, a date and a score settles most disputes before they become arguments, and it changes behaviour, because people clean differently when they know the room will be photographed.

Supervising a crew you did not hire

You cannot manage an agency worker the way you manage your own employee. You do not control their hours, pay, discipline or next shift. What you control is access, scope and acceptance.

• Set the acceptance bar and hold it. If the first visit misses the standard, say so in writing on the day, with the score and the photos.
• Take patterns, not incidents, to the agency's supervisor. One missed restroom is a bad night; the same restroom missed four weeks running is a resourcing problem the agency owns.
• Use a structured supervisor walkthrough on the same route each night to catch drift early, as set out in the cleaning supervisor daily routine.
• Never let an agency worker operate equipment or chemicals they have not been inducted on — critical
• Escalate individuals separately from the contract. Ask for a worker to be replaced before you threaten the agreement.

Document every conversation. A pattern of documented, proportionate communication is what makes a termination defensible.

Where a labour agency differs from a subcontractor

An agency is not a cleaning subcontractor, even when the workers are cleaning. The agency supplies people; you supply the method, supervision, chemicals and equipment.

Scope note: Employment classification, payroll obligations and workers' compensation coverage belong to the labour agency, not to you. Confirm the arrangement in writing, and take advice before treating agency workers as your own employees.

• You supervise the work; the agency employs the person. Train them on your tasks; do not manage their attendance or discipline.
• Do not move agency workers between sites without telling the agency. Access, insurance and site induction depend on knowing who is where — critical
• Check coverage before the first shift, every year, and after any change of ownership — critical
• Do not hand your chemicals to agency staff who have not been inducted on them — critical

Safety obligations do not subcontract

Health and safety duties follow the work. If an agency worker is injured on a site you control, you will be asked what you did to prevent it, and "they were not my employee" is not an answer that holds up. Canada's occupational health and safety legislation sets out employer, supervisor and worker duties across fourteen jurisdictions, summarised by CCOHS.

• Induct for hazards, not just for tasks. Slips, chemicals, ladders, electrical rooms and lone working.
• Give subcontracted workers an explicit incident and near-miss reporting route — critical
• Never ask an agency worker to do a task outside the written scope to save time. Confined spaces, clinical waste, pest treatment, machinery and electrical work belong to qualified specialists. Report, do not act.
• Keep training current. A lapsed WHMIS certificate is a finding waiting to be written up — critical

Paying for performance

Payment terms are the most effective quality lever you have, and the least used. Three structures work.

1. Fixed fee with a quality floor. Full payment above an agreed score, a defined deduction below it, and a second consecutive failure triggering a formal improvement notice.
2. Per-visit rate with an acceptance step. The supervisor signs off the visit against the checklist before the visit is invoiced.
3. Retainer plus performance element. A base rate covering availability, plus a variable portion tied to inspection results and close-out times.

Whichever you choose, put the arithmetic in the subcontract. "Payment may be reduced for poor performance" is unenforceable in a disagreement. "A site score below 3.0 on the APPA 1–5 scale for two consecutive inspections entitles the client to reduce that month's invoice by 10 per cent for the affected areas" is not.

Building a program that survives growth

Subcontractor management is a system, not a relationship. Companies that run it well keep one specification per site that both their own crews and their subcontractors work from, run the same inspection schedule regardless of who is on the floor, and keep the evidence where a client or insurer can be shown it quickly. Cleaning specification writing covers scope that survives a dispute; service level agreements covers the measurement side.

Where this fits in the quality system

This sits under our building a quality assurance program, which sets out the standard these checks are measured against.

Frequently asked questions

Should a cleaning contractor use subcontractors or hire directly?

Use subcontractors when the work is variable, geographically distant, or needs a skill you do not employ. Hire directly for recurring core work on your main sites, because you control training, conduct and cost.

How often should subcontracted areas be inspected?

At least as often as your own crews' areas, and more often during the first month with a new subcontractor. A weekly scored inspection with photos is a workable default for nightly work.

Who is responsible if an agency worker is injured on site?

Both parties usually carry duties. The agency has employer duties to its worker, and you have duties as the party controlling the workplace, which is why induction and incident reporting must cover subcontracted workers explicitly.

Can we reduce payment for failed inspections?

Yes, if the subcontract says so in specific terms. State the score threshold, how many consecutive failures trigger a deduction, the percentage, and the notice you will give.

What records should we keep for subcontracted cleaning?

Keep the signed subcontract and scope, current insurance and workers' compensation certificates, induction and training records per worker, scored inspections with photos, the deficiency log with close-out dates, and incident reports, all filed against the site.

Making subcontracted labour accountable

The test of a subcontractor program is simple. For any client site, on any date, can you produce the specification, the induction record, the inspection score, the photos and the closed deficiencies? If the answer takes a week of digging through email, the program is not working yet. Apply the same induction discipline to your own hires, as described in training and onboarding cleaning staff.

NeatScore keeps multi-site checklists, critical items, photos per item, offline inspections that sync, and branded PDF reports in one place, so a subcontractor's work is scored and documented the same way yours is. Try it free for 14 days, or see pricing.
