The market is filled with providers offering different service models, strengths, and pricing structures, making a direct comparison challenging for busy facility managers and business owners.
This guide provides an impartial, evidence-based framework to simplify the decision-making process. It offers a detailed look at seven reputable cleaning companies serving the Markham area, moving beyond marketing claims to focus on consistent, practical criteria. A professionally cleaned workspace not only improves aesthetics but also plays a vital role in maintaining clear office spaces, which directly contributes to better organization and employee efficiency.
The objective is to equip you with the knowledge to choose a cleaning service that aligns with your facility’s specific needs, quality standards, and budget.

Commercial office cleaning refers to professional cleaning services contracted by businesses and organizations for their workplaces, rather than for residential homes. The scope of these services is tailored to the specific needs of a commercial environment, focusing on areas that support employee health, safety, and productivity.
Unlike residential cleaning, commercial services often involve specialized equipment, industry-grade cleaning products, and adherence to specific health and safety standards like WHMIS (Workplace Hazardous Materials Information System). The service can range from daily janitorial tasks to periodic deep cleaning and disinfection. Key areas of focus typically include:
A well-defined scope of work is essential for any commercial cleaning contract, as it outlines exactly what tasks will be performed, at what frequency, and to what standard.
Arelli Cleaning has built a strong reputation in the commercial cleaning sector across the Greater Toronto Area by integrating technology-driven management with a client-focused service model. This approach makes them a notable option for businesses in Markham seeking reliable and accountable commercial office cleaning services. They serve a diverse range of facilities, from corporate offices in Downtown Markham to medical clinics in Unionville and industrial spaces in Buttonville, by providing customized cleaning plans.
A key differentiator is the company's proprietary Advanced Commercial Cleaning Management System (ACCMS). This platform, which includes a smartphone app, establishes a direct communication channel between clients, cleaning crews, and management. It facilitates real-time issue reporting, digital quality control inspections, and transparent accountability, helping to ensure consistent service delivery. This system offers a more immediate and documented process for quality assurance compared to traditional communication methods.

Arelli Cleaning’s operational model is centred on flexibility and earning client trust. They offer no-term contracts, a significant departure from the industry norm of long-term commitments. This policy, combined with zero cancellation fees, incentivizes the company to consistently deliver high-quality service to retain clients. This approach can be particularly beneficial for small and medium-sized businesses that prioritize adaptability.
Safety and compliance are also core pillars. Crews receive training according to WHMIS (Workplace Hazardous Materials Information System) standards and follow protocols aligned with the Cleaning Industry Management Standard (CIMS). Furthermore, they use Health Canada-approved disinfectants, a critical consideration for healthcare facilities, schools, and offices focused on employee health. To understand their specific offerings, you can explore their office cleaning services.
Practical Insight: A notable feature of Arelli's model is the free 45-minute sample clean offered with every quote. This allows potential clients in areas like South Unionville to experience the quality of work firsthand before making a commitment, reducing the risk associated with hiring a new provider.
Arelli Cleaning's combination of technology, flexible terms, and a commitment to its local crews makes it a compelling choice. The company directly employs and supports its teams, avoiding a franchise model, which can foster a greater sense of ownership and accountability among staff. With over 100 crews and 300 clients, their high client retention rate and positive testimonials reflect the effectiveness of this system.

ServiceMaster Clean is a widely recognized national brand that offers a broad range of commercial office cleaning services through an extensive network of franchises across Canada. For businesses in Markham, from corporate offices in Downtown Markham to facilities in Buttonville, this platform provides a reliable resource for scheduled janitorial services, floor care, and disinfection programs. It caters to a diverse clientele, including single-site small businesses and large national corporations with multiple locations.

A notable aspect of ServiceMaster Clean is its transparent approach to entry-level pricing. The website openly states that janitorial plans can start from $250 per month, which gives potential clients a helpful baseline for budgeting purposes. This is especially useful for new businesses or those exploring professional cleaning services for the first time. The site clearly outlines its core offerings, which include daily office cleaning, carpet and upholstery care, and more intensive jobs like post-construction cleanup. For businesses that require specialized attention, understanding the full scope of a provider is critical. To learn what these specialized jobs typically involve, you can explore details on specialty cleaning services.
The website is structured to guide users to the services most relevant to their industry, whether it's a healthcare facility in Unionville or a professional services firm. The National Accounts Program is a key feature for companies managing properties across multiple provinces, as it aims to provide a standardized level of service and centralized billing.
Practical Tip: When contacting a franchise-based service like ServiceMaster Clean, it is advisable to ask about the specific training and quality assurance protocols followed by the local team that would be assigned to your facility. This helps ensure the national standard is consistently met by your local provider.
A significant advantage is the company's strong brand recognition and the reassurance that comes with a service guarantee and standardized training programs for its franchisees. The published starting price provides a clear, though introductory, financial benchmark.
However, the franchise model can sometimes lead to variability in customer experience from one location to another. While the brand sets standards, the execution is ultimately managed by individual franchise owners. Furthermore, while an entry-level price is published, detailed quotes for a specific scope of work require a direct consultation and are not available online.

Bee-Clean Building Maintenance is Canada’s largest Canadian-owned janitorial company, offering a nationwide scale of operations. For businesses across Markham, from multi-tenant office buildings to large industrial sites, Bee-Clean presents a robust option for comprehensive commercial office cleaning services. The company cleans hundreds of millions of square feet daily, demonstrating a capacity to handle everything from single-location businesses in Unionville to complex, multi-site enterprise portfolios.

What makes Bee-Clean a significant contender is its strong focus on green cleaning and validated quality systems. The company promotes its "Bee-Green" program, which prioritizes sustainable cleaning practices and products. This commitment is supported by its CIMS-GB (Cleaning Industry Management Standard - Green Building) with Honours certification from ISSA, a key credential for businesses focused on corporate social responsibility and environmental standards. The website clearly segments its expertise across various sectors, including corporate offices, healthcare, and retail, allowing potential clients to easily identify relevant capabilities. This emphasis on documented, independently verified quality offers a layer of assurance, which you can learn more about in this guide to keeping offices clean.
The website is designed to communicate corporate strength and reliability. Users can navigate through sections dedicated to specific industries, helping them understand the company’s experience in environments with unique demands like healthcare facilities. A key feature is the coast-to-coast network of branches with 24/7 service capability, offering a standardized solution for national companies seeking a single-vendor relationship for all their locations.
Practical Tip: When evaluating a large provider like Bee-Clean, ask for details on its CIMS-GB certification and how the principles of their Bee-Green program translate into daily operations at your specific site. This can include questions about the chemicals used, waste reduction policies, and staff training.
A primary advantage is the company’s scale and strong position on compliance and sustainability. The CIMS-GB with Honours certification provides third-party validation of its management and operational standards, which is a powerful trust signal for large corporate clients. Their extensive experience across diverse sectors demonstrates a capacity to handle complex logistical challenges.
On the other hand, the enterprise scale of Bee-Clean might make it less suitable for very small businesses or those requiring simple, ad-hoc cleaning jobs. The engagement process is geared toward formal requests for proposals (RFPs) and detailed quotes, as the company does not publish a rate card or entry-level pricing.

GDI is a publicly traded, North American facilities services company with a significant Canadian presence. For businesses in Markham requiring more than basic cleaning, from large corporate headquarters in Downtown Markham to complex industrial sites, GDI offers a single-vendor solution for a wide range of needs. The platform is designed for clients who need integrated commercial office cleaning services, disinfection programs, and even technical facility maintenance under one contract, making it a strong choice for multi-site operations and complex facilities.

What makes GDI a distinct entry is its emphasis on technology and integrated quality assurance systems. The company uses proprietary applications like GDI Inspect, FotoFinish, and FotoFeedback to document and verify cleaning performance, offering a high level of transparency to facility managers. This focus on verifiable data is crucial for businesses that must meet stringent compliance standards or want objective proof of service quality. The website details their ISO 9001 certified quality management systems and green cleaning programs, appealing to organizations with specific corporate governance or sustainability goals.
The GDI website serves as a corporate portal, detailing its extensive service offerings that go beyond janitorial work to include technical trades and building maintenance. A key feature is their ability to deliver a consolidated service model, where one provider manages everything from daily cleaning to HVAC maintenance. This integration is particularly valuable for property managers and operations directors in Markham looking to simplify vendor management.
Practical Tip: When exploring GDI’s offerings, it is useful to focus on their case studies and industry-specific sections. This can help you understand how their integrated model and technology stack are applied in environments similar to yours, whether it's a healthcare facility in Unionville or a manufacturing plant.
A significant advantage of GDI is its capacity to serve large, multi-site clients with a standardized and technologically backed service protocol. Their robust quality assurance stack provides clear performance metrics and accountability. For a business managing multiple locations across Ontario, this single-vendor approach can greatly simplify procurement and operational oversight.
However, GDI’s model is geared towards formal procurement processes, and the website does not provide public pricing information. Obtaining a quote requires direct consultation and is part of a more formal contractual process. For smaller, single-site offices, the onboarding and service structure might be more extensive than necessary.

Jani-King is a long-established global brand with a significant Canadian presence, offering a full spectrum of commercial office cleaning services through its regional franchise network.

The company’s model is built on local franchise delivery overseen by regional offices, covering major Canadian centres including those in Ontario.

What makes Jani-King a fixture in the industry is its decades of market presence and its ability to scale services for diverse sectors.

Potential clients can request a complimentary estimate through the site, which initiates a consultation to develop a cleaning package tailored to their specific needs, from daily upkeep to more intensive tasks.
The website is designed to route potential clients to their nearest regional office, emphasizing the local management and support structure. Users can explore services organized by industry, which helps businesses like a medical clinic in Unionville or a logistics warehouse near Buttonville quickly identify relevant programs. This regional focus ensures that while Jani-King is a national brand, the point of contact and service delivery are managed by a local team familiar with the area.
Practical Tip: When engaging with a Jani-King franchisee, ask about their direct communication process and the role of the regional office in quality assurance. Understanding this two-tiered support system can clarify how performance issues are tracked and resolved.
A primary advantage of Jani-King is its extensive Canadian reach and proven ability to service everything from a small office to a large, multi-building campus. The model of local franchise ownership supported by a regional corporate structure aims to combine the accountability of a small business with the resources of a large corporation.
However, as with any franchise system, the quality of service can vary between individual operators. The brand sets the standards, but the day-to-day execution depends on the local franchisee’s team. Another point to consider is the lack of any published pricing on the website; all cost information is provided only after a direct consultation and site assessment.

The company also actively manages its reputation on third-party review platforms, offering social proof that can help decision-makers gauge customer satisfaction.
Practical Tip: When evaluating a quote from JAN-PRO, ask for specific details on how their EnviroShield system would be applied in your facility, including the frequency and which surfaces would be prioritized. This ensures the branded technology translates into a tangible benefit for your workplace.
A significant advantage of the platform is its streamlined process for obtaining a pricing estimate and the brand's national reach. The strong emphasis on guaranteed satisfaction and a branded disinfection system provides a sense of reliability. Their generally positive aggregated online reviews also serve as a strong trust signal.
However, like other franchise-based models, the quality of service can vary between individual operators. It is important to vet the specific local team. Furthermore, while obtaining a custom quote is easy, no baseline or standardized pricing is available publicly, requiring a direct consultation for budget planning.

A primary advantage is MCA Group's strong regional presence and the convenience of sourcing a wide array of specialty cleaning services from a single local vendor. This can simplify vendor management. Their around-the-clock availability is also a major benefit for businesses that operate outside of standard hours.
On the other hand, the company's services are geographically limited to Ontario, making it unsuitable for businesses that need a standardized cleaning program across multiple provinces. The website does not provide any public pricing or rate information; all quotes are customized and require a direct consultation.

To help decision-makers evaluate their options, this table provides a high-level comparison of the seven providers based on key operational criteria. Use this as a starting point to identify which companies best align with your facility's size, complexity, and priorities.
Choosing a commercial cleaning partner is a significant decision that impacts your workplace health, safety, and professional image. The process should be systematic and look beyond the monthly price.
Step 1: Define Your Scope of Work
Before you request any quotes, create a detailed cleaning checklist for your facility. Walk through your space in Downtown Markham or Unionville and document everything you need cleaned and how often. Be specific about:
Step 2: Research and Shortlist Providers
Use this guide and online research to create a shortlist of 3-4 potential companies that serve Markham. Look for providers with experience in your industry (e.g., medical, industrial, corporate office). Check their online reviews and certifications.
Step 3: Request and Compare Quotes
Provide each shortlisted company with your detailed scope of work to ensure you receive comparable quotes. When comparing them, look at:
Step 4: Ask Critical Questions
During your consultation, ask about:
What is the difference between commercial cleaning and janitorial services?
While often used interchangeably, "janitorial services" typically refer to smaller, everyday cleaning tasks like emptying trash, vacuuming, and cleaning restrooms. "Commercial cleaning" is a broader term that encompasses janitorial duties as well as larger, less frequent jobs like deep carpet cleaning, window washing, and disinfection services.
How much do commercial office cleaning services cost in Markham?
Pricing varies widely based on facility size (square footage), cleaning frequency, the complexity of the scope, and the number of washrooms and kitchens. On average, a small office might pay a few hundred dollars per month for weekly service, while a large facility could be several thousand. Always get multiple customized quotes.
How often should an office be cleaned?
The ideal frequency depends on foot traffic and the nature of the business. A standard office with moderate traffic usually benefits from cleaning 2-5 times per week. High-traffic environments like medical clinics or retail stores may require daily service.
Why is professional office cleaning important for businesses?
Professional cleaning creates a healthier work environment by reducing the spread of germs, dust, and allergens, which can lead to fewer employee sick days. It also maintains a professional appearance for clients and visitors and helps preserve the value of the building's assets, like flooring and fixtures.
Who provides the cleaning supplies and equipment?
Most professional commercial cleaning companies provide their own industry-grade equipment and cleaning chemicals. However, consumable supplies like paper towels, toilet paper, and hand soap are often billed separately or provided by the client. This should be clarified in the service agreement.
What should I look for in a cleaning service contract?
A good contract clearly outlines the scope of work, cleaning frequency, cost, contract term (if any), cancellation policy, liability insurance details, and procedures for resolving issues. Avoid contracts with vague language or long, automatic renewal clauses.
Choosing the right commercial office cleaning service in Markham is about finding a reliable partner committed to quality and communication. A clean and healthy workspace is a foundational element of a successful business, contributing to employee morale, productivity, and a positive brand image.
Use the framework in this guide to conduct a thorough evaluation. Define your needs, compare providers based on value rather than just price, and ask detailed questions about their processes. By investing time in this decision, you can secure a partnership that helps your business thrive. Successful implementation often goes hand-in-hand with effective facility management best practices, ensuring all aspects of your workplace maintenance are aligned.
Start by creating a detailed scope of work, request 2-3 quotes from reputable providers, and don't hesitate to ask for references.
If your business is located in Markham, the GTA, or Southern Ontario, you can consider Arelli Cleaning as one of your options. For a transparent quote that includes a free, 45-minute sample clean of any area you choose, visit their website to learn more about their client-first approach.
