A dirty office reflects poorly on your business—but finding the right commercial cleaning company shouldn't be a hassle. The difference between a mediocre cleaning service and a great one often comes down to how thoroughly you vet your options before signing a contract. This guide walks you through the exact steps to hire a commercial cleaning company that fits your facility, budget, and standards.
Define Your Cleaning Needs
Before you contact a single company, get specific about what you need cleaned. Are you looking for daily office restroom maintenance, weekly floor stripping and waxing, or monthly deep cleans for a warehouse? Document the square footage of your space, the type of flooring, any specialized equipment (carpeted vs. hard floors, high-touch surfaces that need disinfection), and your preferred cleaning schedule.
Make a list of which areas are non-negotiable: restrooms, break rooms, carpeted areas, kitchen facilities, or exterior windows. This clarity prevents you from getting vague quotes or hiring someone who can't handle your specific requirements.
Research Local Providers
Start by searching for commercial cleaning companies in your area or use a platform like Mercoly, which lets you compare and find trusted janitorial cleaning providers all in one place. Check Google Maps, read customer reviews on Yelp and the Better Business Bureau, and ask for recommendations from neighboring businesses. Look for companies that specifically mention commercial or office cleaning—residential-only cleaners often lack the equipment and experience for larger facilities.
Pay attention to red flags: very new companies with no reviews, vague service descriptions, or no physical address listed. Established companies with consistent customer feedback are your safer bet.
Request and Compare Quotes
Contact at least three providers and request detailed written quotes. A professional estimate should break down:
- Frequency and duration of each cleaning visit
- Specific areas covered (restrooms, break rooms, offices, common areas)
- Services included (vacuuming, mopping, trash removal, restocking supplies)
- Special services and their costs (carpet cleaning, window washing, floor stripping)
- Monthly or annual pricing
- Cancellation or rescheduling policies
Avoid companies that give you a price over the phone without seeing your space. Commercial cleaning costs vary wildly—typically $0.05 to $0.25 per square foot for basic cleaning, depending on your region and facility type. A 5,000 sq. ft. office might cost $250 to $1,250 per month for weekly service.
Verify Credentials and Insurance
Ask about liability insurance and workers' compensation coverage. Any reputable commercial cleaning company should carry both—this protects your business if someone gets injured on-site or damages your property. Request a Certificate of Insurance and verify the coverage amounts are adequate for your facility.
Check whether they're bonded (especially important if they'll have key access to your building) and ask about background checks for their staff. If you handle sensitive materials or work in healthcare or finance, compliance certifications may be important—confirm they meet industry standards.
Schedule On-Site Walkthroughs
Invite your top two or three candidates to visit your facility. A good cleaning company will:
- Take notes on problem areas (stained carpets, high-touch zones, tight corners)
- Ask questions about your expectations and pain points
- Point out areas that might need specialized attention
- Discuss their equipment and cleaning products (eco-friendly options, allergy considerations)
This visit tells you a lot about their professionalism and attention to detail. If they rush through the walkthrough or seem disorganized, that's how they'll approach your cleaning.
Review the Contract Carefully
Before signing, review every line of the service agreement:
- Confirm the scope of work matches your needs
- Check the payment terms, billing cycle, and accepted payment methods
- Verify the cancellation clause (most require 30 days' notice)
- Look for guarantees—will they re-clean areas if you're unsatisfied?
- Clarify who handles restocking supplies (paper towels, soap, trash liners)
Don't skip this step to save time. A vague contract leads to misunderstandings and wasted money.
Set Clear Expectations and Start
Schedule a kick-off meeting before the first official cleaning. Walk the team through your preferences, introduce key contact people, and establish communication channels for reporting issues. It's normal to request adjustments after the first week—a good company will make tweaks without pushback.
Frequently Asked Questions
Q: How often should I have my commercial space cleaned? Most office buildings are cleaned daily or 3-5 times weekly, while warehouses or retail spaces might need 1-2 times per week depending on foot traffic and industry; your cleaning company can recommend the right frequency based on your space type.
Q: What should I do if I'm unhappy with the cleaning quality? Contact your provider immediately with specific examples (photos help), give them one chance to correct it, and if they don't improve within a week, invoke your contract's clause to terminate service and hire someone else.
Q: Do I need to provide cleaning supplies, or does the company bring their own? Most commercial cleaners bring their own equipment and chemicals, but clarify who supplies consumables like toilet paper, hand soap, and trash bags—some companies include these, others charge extra or require you to stock them.
