A Guide to Hiring Subcontractors for Cleaning

Before you even think about hiring subcontractors for cleaning, there’s one thing you absolutely have to get right: defining exactly what you need. If you skip this step, you’re setting yourself up for a world of mismatched expectations, spotty service, and wasted money.

It’s a critical first move.

Defining Your Commercial Cleaning Needs

Forget searching for "professional commercial cleaning near me" for a moment. First, you need to create a detailed Scope of Work (SOW). Think of this as the blueprint for your facility's cleanliness. It’s where you translate your expectations into a clear, actionable guide that potential subcontractors can actually use to give you an accurate quote and, more importantly, deliver the results you're paying for.

A solid SOW is the bedrock of a good partnership. It gets rid of the guesswork. Instead of a vague request like "clean the office," a proper SOW lays out frequencies, specific task lists, and any quirks unique to your facility. This level of detail is non-negotiable, whether you run a small law office in Richmond Hill or a massive manufacturing plant in Mississauga.

Tailoring the Scope to Your Facility Type

It sounds obvious, but you’d be surprised how often it's missed: the cleaning needs of a quiet insurance office and a busy factory floor are night and day. Your SOW has to reflect that reality.

• Corporate and Professional Offices: For places like engineering firms, lawyer offices, or insurance companies in Toronto and Vaughan, it’s all about maintaining a sharp, professional image. The SOW needs to focus on daily tasks like dusting all surfaces, vacuuming, disinfecting high-touch points (think doorknobs and light switches), and keeping washrooms spotless. A clean office directly affects how clients see you and how your employees feel.

• Manufacturing & Warehousing: In an industrial setting, the priorities shift to safety and keeping operations running smoothly. The SOW here has to cover things like removing debris from production areas, cleaning employee break rooms and washrooms, and following specific safety rules. A clean factory isn't just for show; it's about preventing accidents.

• Medical and Dental Offices: These facilities are in a league of their own. Health regulations demand the absolute highest standard of cleanliness. Medical office cleaning and dental office cleaning require a laser focus on disinfection. The SOW must spell out the exact protocols for cleaning exam rooms, waiting areas, and offices with the right disinfectants to stop cross-contamination in its tracks.

Here's something to think about: according to ISSA, the worldwide cleaning industry association, a clean environment can boost productivity by as much as 8%. Defining your needs isn't just a chore—it’s a smart business decision that helps your bottom line.

Key Components of a Strong Scope of Work

To build an SOW that actually works, you need to break down your needs into specific, measurable tasks. This document will be the heart of your service agreement, so it's worth getting right.

1. Create a Detailed Task Checklist
Go through each area of your facility and list every single cleaning task required. Don't be vague. Instead of "clean the kitchen," break it down:

• Wipe and sanitize all countertops and tables.
• Clean the microwave, inside and out.
• Wipe down cabinet fronts.
• Empty and sanitize all trash and recycling bins.
• Sweep and mop the floor.

2. Define Cleaning Frequencies
Now, assign a frequency to each task. Some things need to be done every day, while others can be weekly or monthly.

• Daily: Emptying trash, sanitizing washrooms, vacuuming high-traffic areas.
• Weekly: Dusting all surfaces, cleaning interior glass, mopping hard floors.
• Monthly: Wiping down baseboards, cleaning light fixtures.

3. Map Out Your Facility
Include a floor plan or at least a clear list of every area that needs service—offices, hallways, washrooms, lobbies, break rooms, you name it. If you have the square footage, even better. This helps subcontractors give you a much more accurate quote. If you need some ideas for what to include, taking a look at a full list of commercial cleaning services can be a great way to flesh out your SOW.

Okay, you've got your detailed Scope of Work locked down. Now, it's time to switch gears from planning to action. This is where you move past a generic "office cleaning near me" search and start finding professional, reliable subcontractors who can actually get the job done right. Finding names is easy; the real work is in the vetting.

The cleaning industry is massive and, honestly, pretty fragmented. In the GTA alone, you'll find countless small operators working on razor-thin margins. It’s absolutely critical to look beyond the slick marketing and dig into a company’s credentials and real-world track record.

Sourcing Reputable Cleaning Companies

So, where do you start? Your hunt for a professional commercial cleaning partner should begin with credible industry sources. Sure, a quick Google search will give you a long list, but focusing on quality from the get-go will save you a ton of headaches down the road.

A fantastic place to start is with industry organizations like ISSA, the worldwide cleaning industry association. Companies that are members tend to be more committed to professional standards and ongoing training. It shows they're serious about their trade.

Affiliation with a body like ISSA signals that a subcontractor is invested in their craft beyond just showing up with a mop and bucket. They have access to training, certifications, and resources that mark them as a serious provider.

Another powerful sign of reliability? Consistent, third-party recognition. Look for companies that have won awards for service excellence, especially over multiple years. For example, Arelli Cleaning has earned the Consumer Choice Award for the third year in a row. That’s not a fluke; it's a strong indicator of sustained customer satisfaction and high-quality, Award-Winning Service.

The Critical Vetting Process

Once you have a shortlist of potential partners, the real work begins. This is the due diligence phase, and it’s non-negotiable. Before you bring anyone on board, a thorough vetting process is essential. It's really about understanding what due diligence is and applying that discipline to your hiring decision. This isn't just about finding someone who can clean; it's about protecting your business.

Your vetting checklist must include these absolute must-haves:

• WSIB Clearance Certificate: In Ontario, this is mandatory. It proves the company is in good standing with the Workplace Safety and Insurance Board, which protects you from liability if one of their workers gets hurt on your property.
• Liability Insurance: Don't even talk to a company that can't show you a certificate of insurance for at least $5 million in commercial general liability. This is what covers potential property damage or accidents.
• Business Registration: A simple but crucial step. Verify they are a legitimate, registered business. This separates the pros from the casual, under-the-table operators.
• Industry Certifications: While not always required, certifications from bodies like ISSA or CIMS (Cleaning Industry Management Standard) show a real dedication to best practices.

Questions to Ask and Red Flags to Watch For

That first consultation is your chance to gauge a company's professionalism and how they operate. Don't just ask about price. You need to probe deeper into their processes, quality control, and how they handle things when they go wrong.

A key differentiator is a company's willingness to prove its quality upfront. A provider confident in their service will often offer a Free 45 minute sample clean of a dedicated area of your facility with every quote. This is an invaluable, risk-free way to see their work firsthand before you commit.

During your conversations, ask specific, targeted questions:

• "How do you train and supervise your cleaning staff?"
• "What is your process for handling a service complaint or a missed task?"
• "Can you provide references from other businesses in our industry, like other law offices or manufacturing facilities?"

Pay close attention to how they communicate. A company like Arelli offers premium customer service availability on site, on the phone, or on our own dedicated smartphone app. That level of accessibility shows they're a client-focused partner and you won't be left chasing them down when you need something.

At the end of the day, whether you need meticulous cleaning for a dental clinic or reliable office cleaning in downtown Toronto, this vetting process ensures you find a partner who provides more than just a service. They provide a Clean Workspace & Peace of Mind.

Crafting a Rock-Solid Service Agreement

Once you’ve narrowed down your list of potential cleaning subcontractors, it’s time to get everything in writing. This is where verbal promises and handshakes become a legally sound service agreement. Don't think of this document as a mere formality—it’s the foundation of your entire partnership.

A well-crafted contract protects everyone involved and makes sure there are no surprises down the road. It’s what creates the conditions for a consistently clean workspace and, just as importantly, your peace of mind. The goal here is to be detailed, leaving zero room for interpretation. It absolutely must include the Scope of Work (SOW) you developed earlier, spelling out every task, frequency, and specific area to be cleaned. Vague contracts are just asking for conflict.

Defining Service Levels and Expectations

A key part of any professional cleaning agreement is the Service Level Agreement, or SLA. This is where you move beyond what gets cleaned and define how well it needs to be done. Think of it as setting measurable, objective standards for quality.

For instance, an SLA might specify that all office wastebaskets must be emptied daily with liners replaced, or that there should be no visible debris left on floors after vacuuming. It can also outline response times for handling complaints or special requests. A strong SLA is your best tool for holding your subcontractor accountable for the quality they promised.

The whole point is to establish clear, objective benchmarks for performance. This gets rid of subjective arguments over whether a job was "done right" and replaces them with a shared, concrete understanding of success.

Payment Terms and Pricing Models

Pricing needs to be crystal clear. The agreement has to outline the cost of services, the payment schedule (e.g., net 30), and how you'll be paying. This is also where you'll lock in the pricing model you negotiated.

Different models work for different situations, so it’s important to land on the one that gives you the best value.

To help you decide, here’s a quick comparison of the most common pricing models you’ll encounter:

Pricing Model Comparison

Choosing the right model ensures you're paying fairly for the services you actually need, without any hidden surprises.

It also helps to have some context on what subcontractors earn. While pricing models dictate what you pay, wage patterns can vary a lot by location. National data shows an average U.S. annual pay around $35,034, but in higher-cost areas, that figure can climb significantly—some communities in California report estimates over $55,000. Knowing this helps you understand the quotes you receive, as regional labour costs are a major factor.

Liability, Insurance, and Termination Clauses

This part of the agreement is all about managing risk. It must clearly state that the subcontractor is responsible for carrying their own liability insurance and WSIB coverage. This is non-negotiable, as it protects your business from being on the hook financially if an accident or property damage occurs.

The termination clause is just as important. You’re aiming for a long-term partnership, but business needs can change unexpectedly. Look for a subcontractor who offers some flexibility here. A partner offering a "No cancellation for change fee" policy is a huge plus, giving you the freedom to adapt without a financial penalty.

Your service agreement should be thorough, but it also needs to be a living document. If you need to make changes down the line, using an addendum is the proper way to incorporate updates legally. You can check out a step-by-step guide to writing an addendum for help with that. And if you want to see how these clauses look in a real-world document, feel free to review our own terms of service.

Managing the Partnership for Consistent Results

Getting the contract signed is a great first step, but it’s definitely not the finish line. The real work begins now. A strong partnership with your cleaning subcontractor is what turns that signed agreement into the pristine, reliable results you expect for your facility, day in and day out.

This all kicks off with a detailed onboarding session. Forget just handing over a set of keys. This needs to be a strategic walk-through of your facility with the subcontractor’s operations manager and the actual crew assigned to your site. Pull out the Scope of Work (SOW) from your service agreement and use it as your map, pointing out specific areas of focus, security protocols, and any quirks of your space—whether it's a medical office in North York or an engineering firm in Vaughan.

This first meeting sets the tone for everything that follows. It's your chance to translate the words on the page into real-world expectations and give the cleaning team a practical feel for your needs.

Establishing Clear Communication Channels

When a cleaning issue pops up—and they occasionally do—you need a fast, reliable way to get it sorted. Vague communication is a recipe for frustration and service gaps. The best commercial cleaning partners make it effortless to get in touch.

Today, modern, client-focused companies use technology to make this seamless. At Arelli, for example, we provide a dedicated smartphone app that lets you submit service requests, flag issues with a photo, and track their resolution in real time. This doesn't replace traditional phone and on-site support; it enhances it, giving you premium customer service whenever you need it. A message sent from your desk in Richmond Hill gets seen and acted on immediately. No more chasing people down.

Setting and Measuring Performance

So, how do you really know if the service is meeting your standards? You can’t just go on feelings. You need to define and track Key Performance Indicators (KPIs). These are the hard numbers that tell the story of your service quality.

Your KPIs should link directly back to your SOW. Good ones to start with include:

• Inspection Scores: The percentage of items passed during a regular quality checklist walk-through.
• Issue Resolution Time: The average time it takes from when an issue is reported to when it’s fully resolved.
• Client Feedback Ratings: Simple, periodic satisfaction scores to gauge overall happiness.

According to some industry analyses, the trend of subcontracting in the service sector is significant. Between 1990 and 2014, employment in California's janitorial industry reportedly increased by 44%, with 38% of janitors working for contractors. This highlights just how critical it is to have solid management systems in place to ensure quality and accountability when you're working with outside partners.

Holding regular performance reviews, maybe quarterly, is essential. These meetings aren't for finger-pointing. They're a chance to look at the KPI data together, go over inspection reports, and offer constructive feedback. It’s a collaborative tune-up that keeps the service sharp and reinforces your standards for professional office cleaning.

The Power of an Award-Winning Track Record

Let’s be honest: managing the relationship is a whole lot easier when you partner with a company that already has a proven commitment to excellence. An award-winning service provider has already demonstrated they know how to keep clients happy.

For instance, Arelli’s recognition with the Consumer Choice Award for three consecutive years (2023, 2024, and 2025) is a powerful signal of reliability. This kind of track record, backed by a Price Match Guarantee, gives you confidence that you’re getting top-tier service at a competitive rate.

A big part of this award-winning approach is our Free 45-minute sample clean, which we offer with every quote. This isn't just a gimmick; it’s a proactive way to show you the quality you can expect, setting a clear benchmark from day one. It’s this dedication to providing a "Clean Workspace & Peace of Mind" that truly sets a premier cleaning partner apart.

Ensuring Quality and Resolving Issues

A signed contract is just the beginning. The real test of a great partnership with your cleaning subcontractor is whether they deliver consistent, high-quality results day in and day out. It’s not about crossing your fingers and hoping for the best; it’s about having a solid system to monitor performance and a clear plan to fix things when they go wrong.

Keeping standards high isn't about micromanaging. It's about getting on the same page about what "clean" actually means for your facility. The best way to do this is with regular, structured inspections. These aren’t random spot-checks; they’re planned walk-throughs using a detailed quality checklist that comes straight from your Scope of Work (SOW).

This simple step turns a subjective feeling into an objective measurement. Instead of just saying a washroom "looks dirty," your checklist will have specific items like, "Mirrors are streak-free," "Soap dispensers are full," and "Floors are clear of debris." This data-driven approach makes conversations with your subcontractor way more productive, focusing on specific fixes instead of vague complaints.

Using Tech to Keep Everyone on Track

These days, smart cleaning management leans on software to make quality control easier and more transparent. Platforms like Janitorial Manager are designed for this, giving you tools to create digital inspection checklists, log issues with photos, and see performance trends over time.

Using a system like this gives both you and your subcontractor a real-time, honest look at service quality. It helps you spot recurring issues before they become big problems and keeps everyone accountable.

This digital paper trail of inspections and resolutions is invaluable. It shifts performance reviews away from "he said, she said" and toward concrete data, building a partnership that’s genuinely focused on getting better.

A Clear Path for Fixing Problems

Let’s be real: even the best crews will miss something now and then. A bin gets overlooked, or a corner isn't dusted to your standard. The key is having a pre-defined process for handling these hiccups so that small issues don’t snowball into major frustrations.

Your process should be simple and escalate logically:

• The Quick Chat: The first step is always a direct, calm conversation. Pull up your inspection report or a photo and clearly show your main contact what the issue is. Most of the time, a simple heads-up is all it takes for a good partner to fix the problem right away.
• Putting It in Writing: If the issue pops up again, document it formally. This could be a quick email or a service ticket through your management app. This creates a written record of the concern, the date, and when you reported it.
• The Sit-Down Meeting: For more persistent problems, it’s time to schedule a meeting with the subcontractor’s management. Use this time to review the service agreement, your inspection data, and the documented issues. The goal is to work together to find a permanent solution.
• The Contractual Route: If quality continues to slip and the subcontractor isn’t meeting the standards in the Service Level Agreement (SLA), your final step is to refer to the contract’s remediation or termination clauses. This should always, always be a last resort.

The goal is to build a relationship where feedback is seen as helpful, not hostile. A truly professional partner will appreciate your input because it helps them deliver on their promise and keep your business.

This becomes even more critical in facilities with strict health codes, like Medical Office Cleaning or Dental Office Cleaning. Here, quality assurance isn't just about appearances—it's about the safety of patients and staff. To understand the protocols needed for these environments, it helps to learn about commercial disinfection and sanitizing. A robust quality system is your best defense against cross-contamination, ensuring your space is always safe and compliant.

Answering Your Top Questions About Cleaning Subcontractors

Hiring a commercial cleaning company can feel like a big decision. How do you know who to trust? What should you look for? Below, we tackle some of the most common questions we hear from businesses, giving you the straightforward answers you need.

What's the Real Difference Between a Subcontractor and an Employee?

This is a big one. When you hire an employee, you’re taking on everything: their wages, benefits, training, equipment, supplies, and direct management. It’s a lot of overhead and responsibility.

Hiring a subcontractor, on the other hand, means you’re partnering with a specialized business. They handle all their own staff, insurance (WSIB), and training. For most businesses that need professional office cleaning or professional commercial cleaning, subcontracting is the smarter, more scalable way to go. It lets you focus on your actual business while an expert partner takes care of keeping your space pristine.

How Can I Be Sure a Cleaning Subcontractor Is Reliable?

Trust is earned, not just promised. Start with the basics: always ask to see a company’s business registration, proof of liability insurance, and a current WSIB clearance certificate before you sign a thing.

But don't stop at the paperwork. Look for real-world proof of their reputation, like customer reviews and industry awards. A one-off award is nice, but consistent recognition signals something more. For instance, Arelli Cleaning is incredibly proud to have won the Consumer Choice Award for three years straight. That’s not a fluke; it's proof of our ongoing commitment to our clients.

The best way to verify quality? See it for yourself. Any confident company should be willing to prove its worth. That's why we offer a "Free 45 minute sample clean of a dedicated area of your facility with every quote." A hands-on demo tells you more than any sales pitch ever could.

What Absolutely Must Be in a Cleaning Contract?

A solid commercial cleaning contract leaves no room for confusion. It needs to spell out the complete scope of work, how often services will happen, and the specific tasks for every single area of your facility. It should also clearly define the pricing, payment schedule, and terms for ending the contract.

More importantly, it must outline insurance and liability responsibilities to protect your business. Look for clauses that show a company stands behind its service, like a "Price Match Guarantee" or a "No cancellation for change fee" policy. These aren't just perks; they show the provider is confident and puts its clients first.

How Do You Actually Manage Quality Control With a Subcontractor?

Good quality control isn’t about micromanaging; it’s about clear expectations and great communication. It all starts with that detailed scope of work. From there, you should have a schedule for regular inspections, ideally using a checklist to keep things objective.

The best partners make communication easy. Having access to premium customer service availability on site, on the phone, or on our own dedicated smartphone app means you can give feedback instantly and know it will be addressed. A proactive cleaning partner welcomes this kind of collaboration because you both share the same goal: maintaining a high standard and delivering that feeling of "Clean Office & Peace of Mind."
