5 Questions to Ask Before Hiring Commercial Cleaning Services in London, Ontario

Choosing commercial cleaning services in London, Ontario is a decision most business owners don’t spend nearly enough time on, until something goes wrong. A missed clean, a damaged floor, a staff member who discovers their office was improperly accessed, or worse, an injury on your premises caused by an uninsured contractor. By the time these problems surface, you’re already dealing with fallout that a few better questions upfront could have prevented entirely.

The commercial cleaning services London businesses have access to run the full spectrum. There are outstanding, professional operators who invest in training, use proper products, carry full insurance, and deliver consistent results week after week. There are also cut-rate providers who underbid to win contracts, send undertrained staff with inadequate products, and disappear when something goes wrong. The difference between these two categories isn’t always obvious from a quote sheet, which is exactly why the questions you ask during the evaluation process matter so much.

This post walks through the five most important questions to ask any commercial cleaning service in London before you sign a contract. They’re designed to separate the providers worth trusting from the ones worth avoiding, and to give you a clear framework for making a decision you’ll be comfortable with long after the honeymoon period ends.

Question 1: Are the Staff Your Commercial Cleaning Services Send Insured, Bonded, and Background-Checked?

This is the first question, and it’s non-negotiable. Before anything else, before pricing, before scheduling, before scope of work, you need to know who is actually going to be inside your facility.

Commercial cleaning staff work in your building, often unsupervised, frequently after hours. They have physical access to your offices, your equipment, your files, and in many cases, areas your own staff rarely enter. The trust you extend to a cleaning team is significant, and it should be backed by verifiable credentials.

What Each Term Actually Means

These three terms are sometimes used interchangeably or loosely, but they mean distinct things:

• Insured means the company carries liability insurance that covers damage to your property or injury to a staff member while on your premises. Without this, you could be liable for an injury that occurs during a cleaning visit, or left without recourse if something in your office is damaged.
• Bonded means the company carries a surety bond that provides financial protection if a cleaning employee steals from your facility. In a commercial cleaning context, bonding is a meaningful assurance, not just a marketing term.
• Background-checked means staff have been screened for criminal history before being placed in client facilities. This is standard practice among professional operators and non-existent among cut-rate ones.

At MedClean, every technician is fully insured, bonded, and background-checked before they set foot in any client facility. We understand that you’re extending genuine trust when you hand over access to your building, and we treat that trust accordingly.

Question 2: What Products Do Your Commercial Cleaning Services Use, and Are They Right for My Facility?

This question reveals more about a cleaning company’s professionalism than almost anything else. The products a commercial cleaning service uses determine not just how clean your facility gets, but how safe it is for the people who work in it, and how protected your floors, fixtures, and finishes are over the long term.

Many budget cleaning providers stock whatever is cheapest and most readily available at a big-box store. These products are formulated for general household or light commercial use, not for the bacterial load and hygiene requirements of a professional office or healthcare-adjacent environment. They’re also not always appropriate for every surface, and using the wrong product on the wrong surface causes damage that compounds over time.

What Good Answers Look Like

A professional commercial cleaning company should be able to tell you:

• What disinfectants they use and whether they are Health Canada-approved for commercial and/or healthcare settings
• Whether their products are appropriate for the specific surfaces in your facility, hard floors, carpet, glass, stone, stainless steel
• Whether they offer fragrance-free or low-VOC options for facilities with staff who have allergies or sensitivities
• Whether their products are environmentally responsible, biodegradable, low-impact formulations that align with sustainability commitments

For certain facility types, medical and dental offices, child care centres, food-handling businesses, product selection isn’t just a quality question, it’s a compliance and safety question. A cleaning company servicing these environments should be using clinical-grade disinfectants rated to eliminate the specific pathogens relevant to those settings.

MedClean uses medical-grade, Health Canada-approved disinfectants on every clean, in both scented and completely fragrance-free formulations. We select products based on the specific requirements of each facility type, not on what’s cheapest to stock.

Question 3: Can the Commercial Cleaning Services You’re Considering Provide a Written Scope of Work?

Verbal agreements have a way of becoming very expensive misunderstandings. When a cleaning company tells you they’ll “take care of everything” or “clean the whole office,” those words mean different things to different people, and the gap between what you expect and what gets delivered is where most commercial cleaning disputes are born.

A written scope of work is the document that defines exactly what services are included in your agreement, at what frequency, and to what standard. It should specify every area of your facility, every task category, how often each task is performed, and what falls within and outside the standard agreement.

Why This Matters More Than the Price

Two cleaning quotes that look similar on paper can represent dramatically different levels of service depending on what’s actually in the scope. A quote of $X per month from one provider might include daily washroom disinfection, weekly interior window cleaning, and monthly floor treatment. The same dollar figure from another provider might cover only basic vacuuming, bin emptying, and a wipe-down of obvious surfaces.

Without a written scope of work, you have no basis for accountability when tasks aren’t completed. A professional cleaning company will have no hesitation providing this document, it protects both parties and is the foundation of a functional service relationship.

• Ask to see a sample scope of work before signing anything
• Make sure every area of your facility is explicitly named, don’t accept vague language like ‘all common areas’
• Confirm that daily, weekly, and monthly tasks are clearly distinguished
• Ask what happens if a task is missed, is there a process for reporting and remedying gaps?

MedClean provides every client with a detailed, written scope of work before any service begins. It’s not a formality, it’s the foundation of the service relationship, and it ensures that both parties have a shared, clear understanding of what’s included.

Question 4: How Do Their Commercial Cleaning Services Handle Consistency and Quality Control?

Inconsistency is the most common complaint about commercial cleaning services, and it’s the one that erodes client relationships faster than almost anything else. The first month is great. The second month is mostly fine. By month four, the standard has drifted noticeably, and you’re spending management energy chasing down missed tasks instead of running your business.

This drift isn’t always intentional. It often reflects a lack of systems, no documented checklists, no supervision structure, no process for checking that work has been completed to standard. The question of how a company handles quality control tells you a great deal about whether they’re the kind of operation that invests in consistent delivery or one that relies on good first impressions.

Questions to Ask Within This Question

• Do your cleaning staff work from a documented checklist on each visit?
• How is completed work verified, by a supervisor, by a client check-in process, or not at all?
• What is your process when a client reports that something was missed or not completed to standard?
• Do you have a dedicated account manager or point of contact for client concerns?
• How do you handle staff turnover? Is there a structured onboarding process so that a new technician assigned to my facility maintains the same standard?

Staff turnover is a particular challenge in the cleaning industry, and it’s worth asking about directly. A company that loses a reliable technician and replaces them with someone untrained in your facility’s specific needs can see its service quality drop sharply without any apparent change in the contract. A professional operator has systems that survive individual staff changes, documented procedures, training protocols, and supervision structures that maintain consistency regardless of who shows up.

MedClean operates with structured, checklist-driven cleaning programs on every account. We don’t rely on memory or habit to ensure tasks get done, we build systems that deliver the same thorough standard on every visit, regardless of which technician is on site.

Question 5: Do Their Commercial Cleaning Services Include Experience With Facilities Like Mine?

Commercial cleaning is not a one-size-fits-all service. A medical office in London’s Westmount area has materially different cleaning requirements than a law firm on Clarence Street, which has different needs than a manufacturing-adjacent office on Exeter Road, which is different again from a retail space on Dundas Street or a child care centre near Fanshawe College.

Experience with your specific facility type matters. It affects what products are appropriate, what protocols need to be followed, what areas require the most attention, and whether the cleaning team will recognize and respond correctly to the specific conditions your space presents. A company that has spent years cleaning general offices but has never worked in a healthcare-adjacent environment, a food service facility, or a child care centre is not the right fit for those environments, regardless of how competitive their pricing is.

Industry-Specific Considerations for London Businesses

Here are some examples of how facility type shapes cleaning requirements in ways that demand relevant experience:

• Medical and dental offices require clinical-grade disinfection protocols, specific product certifications, and staff trained in infection prevention and control principles. A general commercial cleaner applying standard office protocols in a medical setting creates real compliance and patient safety risk.
• Child care centres and preschools require low-toxicity, child-safe products; after-hours scheduling so children are never exposed to cleaning activity; and an understanding of the Ontario CCEYA licensing requirements that cleaning practices must support.
• Food-handling or food-adjacent businesses require food-safe cleaning solutions in kitchen and preparation areas, and staff who understand the difference between cleaning, sanitizing, and disinfecting in that context.
• High-rise office buildings and multi-tenant commercial properties require coordination with building management, awareness of shared-space protocols, and often specific insurance requirements above what a single-tenant commercial clean demands.

Ask specifically about their experience with your facility type, not just how long they’ve been in business. Request references from similar clients if you want to verify their claims. A provider who can point to a track record with facilities like yours is a fundamentally lower-risk choice than one who’s confident they can figure it out.

MedClean’s experience spans medical and dental offices, child care centres, commercial offices, retail environments, post-construction sites, and more, across London’s full commercial geography. Explore the range of cleaning solutions we offer to see if your facility type is in our wheelhouse.

Bonus: The Question Most People Forget to Ask

Beyond the five questions above, there’s one more that experienced facility managers often wish they’d asked upfront:

What Does Your Off-Boarding Process Look Like?

It sounds counterintuitive to ask about ending a relationship before it starts, but the answer tells you a great deal about a company’s professionalism and confidence in their own service. A strong commercial cleaning provider will have a clear, professional process for transitioning out of a client relationship if things don’t work out, returning keys and access credentials promptly, completing any outstanding obligations, and handling the transition without drama.

A provider who responds to this question with discomfort or evasiveness may be planning to make exit difficult, long lock-in clauses buried in contracts, automatic renewal terms that are hard to exit, or informal arrangements designed to create dependency. Read contracts carefully, understand your notice period requirements, and make sure you have a clear path out if the service doesn’t meet expectations.

The best cleaning companies in London, Ontario don’t need onerous contracts to retain clients, they retain them by consistently doing excellent work.
