Finding the best janitorial services isn’t easy — but it’s absolutely possible. We’ve created a twenty-point framework for identifying high-quality janitorial services in Michigan and beyond. Twenty points may sound like a lot, but asking the right questions upfront dramatically increases your chances of choosing a professional, reliable partner who can maintain your facility at the level you expect.
Janitorial companies come in all sizes, yet only a small percentage are equipped to service larger facilities with the professionalism, responsiveness, and consistency required. Whether you're searching for the best janitorial services in Detroit or narrowing down office cleaning options for your building, these twenty points represent the core qualities that separate exceptional janitorial companies from the rest.
So, what is the secret to finding the best janitorial services? Start here — with the twenty factors below that will help you cut through the noise and identify a true facility maintenance partner.
1 — Transparent Janitorial Pricing & Clear, Accurate Cleaning Bids
Pricing should never be vague or confusing. If a cleaning company can’t clearly explain their pricing — or plays games with hidden fees — they should be removed from consideration immediately. Transparency is a minimum requirement for trustworthy service.
2 — Good People & Legal Hiring
People are the foundation of every service business. A reputable janitorial company will avoid illegal subcontracting, follow all employment laws, and actively work to attract and retain reliable, professional staff.
3 — Strong Security & Proven Compliance
Cleaners are in your building when few others are present. The best companies perform thorough screenings — background checks, drug testing, reference verification — to ensure safety and protect your facility.
4 — Thorough, Consistent & Specialized Training
A janitorial provider cannot deliver quality without quality training. Look for companies with structured training programs covering safety, general cleaning, and the unique needs of your facility.
5 — A Real Commitment to Health & Safety
Health and safety must guide everything a janitorial company does — from screening employees, to choosing cleaning chemicals, to reducing airborne contaminants and preventing the spread of illness.
6 — Understanding the Science of Clean
Effective cleaning is grounded in science. A qualified provider understands cross-contamination, hot spots, infection control, and the principles behind Cleaning for Health.
7 — Innovative Cost-Saving Solutions
The right provider knows how to reduce costs without sacrificing quality. This includes methods like Smart Cleaning and Team Cleaning, which increase efficiency and eliminate unnecessary labor.
8 — Insurance Coverage & Risk Management
A professional company protects both itself and you. They must carry general liability, workers' compensation, automobile liability, and umbrella coverage — and should willingly verify it.
9 — Lower-Than-Average Janitorial Turnover
With industry turnover at nearly 200%, excellent companies stand out by doing better. Low turnover means experienced, trustworthy staff — and far fewer disruptions in your building.
10 — Individualized, Facility-Specific Services
No two buildings are alike. Avoid companies that base quotes solely on square footage. The best providers assess how your space is used and build a custom plan based on your actual needs.
11 — Responsiveness
Mistakes happen, but the best companies have a formal system for resolving issues quickly. If a provider can’t explain how they handle complaints, they aren’t prepared to support your facility.
12 — Clear, Reliable Communication
You need a direct point of contact — someone who responds promptly, keeps you updated, and ensures accountability throughout the partnership. Communication is a core part of consistent service.
13 — Systems & Processes That Ensure Accountability
Great service comes from strong internal systems — for hiring, inspections, training, pricing, quality control, and more. Without these processes, reliability is impossible.
14 — Professionalism
Professionalism extends far beyond uniforms. It reflects how a company quotes work, trains teams, communicates, documents procedures, and handles challenges. Look at every interaction — it reveals everything.
15 — Modern Technology that Boosts Efficiency & Reduces Costs
Technology is reshaping the cleaning industry. From advanced equipment to automated inspections and reporting, the best companies use modern tools to improve results, reduce waste, and control costs.
16 — A Broad, Valuable Menu of Services
Many high-level janitorial companies offer additional building services — from carpet care to window washing to light maintenance. Consolidating services under one provider saves time and money.
17 — A Proven Track Record of Industry Best Practices
Best practices create consistency. Look for providers who follow recognized industry standards, such as those outlined in ISO certifications or CIMS guidelines, to ensure quality and compliance.
18 — Green Cleaning & Sustainability
A true green cleaning program goes beyond chemical choices. It includes reducing waste, protecting air quality, and cleaning in ways that support a healthier facility and a healthier planet.
19 — Value
The right provider delivers value — not just a low price. Value means receiving the services your facility actually needs, at a fair cost, with consistent quality and measurable results.
20 — CIMS Certification
The previous 19 factors are important — but CIMS certification allows you to verify them instantly. Companies with CIMS-GB certification have already demonstrated that they follow industry best practices, meet rigorous standards, and operate at a high professional level.
Starting your search with CIMS-certified companies is the easiest way to identify strong candidates — and ensure you get the best value and best fit for your facility.
