How to Choose the Right Janitorial Company for Commercial Cleaning

A practical guide to evaluating commercial cleaning service providers, checking quality control, and making a confident hiring decision.

Hiring a commercial janitorial company is a real business decision. You're giving someone regular access to your building, trusting them to show up on schedule, and counting on them to handle the work without close supervision.

Most businesses have straightforward office cleaning needs. Others require more specialized cleaning services for medical facilities, industrial spaces, or multi-tenant buildings. Either way, the evaluation process is the same: you want a janitorial service with real experience and a reputation for consistent, reliable work.

This guide is written for facility managers, office managers, property managers, and business owners who want a practical framework for evaluating cleaning companies, asking the right questions, and making a confident choice.

If your facility is in the Philadelphia suburbs, Montgomery County, Chester County, Delaware County, or Bucks County, you'll find some local context woven in as well.

Key Takeaways

• Know your cleaning needs first. The scope of the work matters before you can compare vendors fairly.

• Insurance is not optional. Verify liability coverage and workers' compensation before signing anything.

• Ask how the work gets checked. Quality control measures separate reliable service providers from inconsistent ones.

• Who actually does the cleaning matters. In-house team members and subcontractors are not the same thing.

• Communication should be easy. If it takes days to get a response before you've hired them, that pattern tends to continue after you sign.

A site visit is a baseline expectation. Any cleaning company quoting without seeing your facility is working from assumptions.

Start by Defining Your Cleaning Needs

Before you talk to a single vendor, get clear on your own requirements. A lot of buyers go into this process without a baseline, and that makes it harder to compare quotes or push back on what's missing.

Think through the basics:

• How large is the space you need cleaned?

• How many days per week do you need service?

• Do you need cleaning done after hours, or does a daytime presence make more sense?

• Are there specific areas that need special attention, like restrooms, breakrooms, or high-traffic lobbies?

• Do you require any additional services beyond routine cleaning, such as floor care, exterior cleaning, or post-construction cleanup?

• Do you have any industry requirements or standards that affect how cleaning is done?

Once you have those answers written down, you're in a better position to have a meaningful conversation with a vendor and spot when a proposal doesn't match what you actually need.

If you're not sure what services are typically included in commercial janitorial contracts, D&D CleanIt's full services page gives you a clear picture of what's commonly covered.

Look at Who Owns the Work

One of the most important but least-discussed questions in commercial cleaning is whether the company you hire actually performs the work.

Many janitorial companies rely on subcontractors. They bring you the contract and hand the work off to someone else. That's not uncommon in the industry, but it can affect consistency, accountability, and security.

In-House Teams vs. Subcontractors

A company that uses an in-house team has direct control over who enters your building, how they're trained, and how they're managed on a daily basis. They own the quality control process, and they invest in ongoing employee training to keep service standards consistent.

A company that subcontracts may offer a lower price, but the people who show up may have different training, different standards, and a different relationship with accountability than the vendor you hired.

It's worth asking directly: do your team members work for your company, or are they independent contractors?

D&D CleanIt uses trained in-house team members, no subcontractors. You can see more about how that shapes the work on the Why Choose Us page.

Verify Insurance Before Anything Else

Any commercial cleaning company operating in your facility needs to carry appropriate insurance, and you should verify it before signing a contract.

At a minimum, ask for proof of:

• General liability insurance. This covers damage to your property or third-party claims that arise from cleaning operations.

• Workers' compensation insurance. If a team member is injured while working in your building, workers' comp protects you from being liable.

• Bonding. A surety bond provides an additional layer of protection against theft or dishonesty.

Don't just take a verbal confirmation. Ask for certificates and, if you have any doubt, contact the provider listed on the certificate to verify the policy is current.

A reputable company will provide this documentation without hesitation.

Understand Quality Control Before You Commit

Commercial cleaning services often run after hours or between your business operations. You won't be watching. That makes quality control one of the most important factors to evaluate when comparing cleaning companies.

Strong commercial cleaning service providers have documented quality control measures — they don't just describe caring about quality, they can explain how they enforce it. Ask any vendor you're considering:

• Do supervisors or managers inspect the work after it's completed?

• How often do inspections happen, and are they documented?

• What happens if something is missed or done incorrectly?

• Is there a way for us to flag issues, and how quickly does the company respond?

Cleaning companies that follow industry best practices and maintain consistent inspection schedules are easier to hold accountable. Look for specifics: who does the inspection, how often, and what the follow-through looks like when something falls short.

What Separates Reliable Cleaning Service Providers From Inconsistent Ones

Use this as a quick reference when comparing vendors side by side.

Understand the Full Scope Before You Sign

A lot of service disputes come down to scope confusion. The client expected certain tasks to be included; the vendor did not.

Before you sign any agreement, make sure you understand exactly what is included in the base commercial cleaning service and what costs extra. Common areas where this breaks down:

• Floor care. Routine sweeping and mopping are usually included. Refinishing, stripping, or deep carpet cleaning are often separate line items.

• Restroom supplies. Some companies include consumables; most do not. Clarify who provides soap, paper towels, and liners.

• Day porter services. Daytime cleaning and common area maintenance are separate from evening or overnight cleaning programs.

• Post-construction or event cleaning. These specialized cleaning services are almost always quoted separately from routine contracts.

• Exterior cleaning. Windows, pressure washing, and soft washing are typically add-ons.

D&D CleanIt offers both routine cleaning programs and day porter services for clients who need a consistent daytime presence. Understanding the difference helps you build the right plan for your facility.

Security and Access Handling

When you hire a cleaning company, you're giving them access to your building — often after hours. That means keys, key fobs, swipe cards, alarm codes, and sometimes access to sensitive areas.

Ask any vendor you're seriously considering:

• How are keys and access credentials tracked and stored?

• Do your team members go through background checks before they work in client facilities?

• What happens if a key is lost or an alarm code needs to be changed?

• Do team members work in uniforms and arrive in identifiable vehicles?

Uniforms and branded vehicles matter more than they might seem. Your staff, building tenants, and security personnel should be able to identify who belongs in the building.

A company that takes security seriously will answer these questions directly and without hesitation.

Don't Skip the Site Visit

Any cleaning company that quotes your facility without seeing it is working from assumptions. They don't know your floor plan, your traffic patterns, your restroom count, your specific problem areas, or anything else that affects how long the job takes and what it actually costs.

A site visit before the quote also gives you a chance to assess the vendor's experience and reputation in person. Pay attention to:

• Do they come prepared with questions about your facility and your needs?

• Are they listening, or are they in sales mode?

• Do they notice things about your building you hadn't mentioned?

• Do they have a realistic sense of what's involved?

The quality of that first conversation tells you a lot about how the company will communicate once you're a client. Cleaning companies that build long-term client relationships tend to earn them through this kind of careful, attentive start.

D&D CleanIt starts every new client relationship with a site visit. We use that to build a custom cleaning plan around your facility, not a generic template. You can learn more about that approach on our About Us page or the Our Commitment to You page.

Check References and Do Some Basic Research

Before you sign with any commercial janitorial company, it's worth doing a quick check on their track record. Ask for references from current or recent clients, particularly those with similar facilities or cleaning needs. A company confident in its work will provide them without hesitation.

It's also reasonable to look at online reviews to get a broader sense of how the company handles day-to-day service and how responsive they are when something goes wrong. No cleaning service has a perfect record, but how a company responds to problems tells you more than glowing reviews.

When you ask for references, be specific: ask about consistency, communication, and whether the scope of work matched what was promised.

Read the Contract Carefully

This is basic advice, but it gets skipped more often than it should. Before you sign, make sure you're clear on:

• The exact scope of work: what is included, what is not, and what is a billable add-on.

• Scheduling and frequency: how many days per week, what time of day, and how schedule changes are handled.

• The cancellation policy: what notice is required, and whether there are early termination fees.

• What happens when something goes wrong: how is a missed night or a service complaint handled?

• Who your point of contact is: is there a specific person you can reach when you have a question or issue?

Price is not the most important thing in a cleaning contract. Scope clarity and accountability provisions are what protect you if something goes sideways.

Ask About Cleaning Products and Indoor Air Quality

If your workplace has specific requirements around chemical use, fragrance sensitivity, or indoor air quality, it's worth raising this before you finalize a vendor. The cleaning products used in your building affect the air your team breathes every day.

Questions worth asking:

• Do you offer green cleaning options?

• What products do you use in restrooms and common areas?

• Are your products appropriate for the surfaces and equipment in our facility?

• Do you use any low-VOC or fragrance-free options for sensitive environments?

D&D CleanIt offers green cleaning options for clients who prefer them. If this matters to your organization, raise it during the evaluation process.

A Note for Philadelphia Suburbs Buyers

If your facility is in Montgomery County, Chester County, Delaware County, or Bucks County, you have access to local commercial cleaning companies that know this market and the specific business needs of facilities in the area.

Local janitorial service providers often have practical advantages over national or regional chains:

• Shorter response times when something comes up

• Management that is personally reachable and invested in the account

• Flexibility to adjust services without working through layers of approval

That doesn't mean every local company is the right fit. All the criteria above still apply. But it's worth factoring in whether you'd rather work with a company where the owner is involved in day-to-day operations or one that routes your calls through a regional office.

D&D CleanIt is based in Audubon, PA and serves businesses throughout the four-county area. You can see which industries and facility types we work with on the Industries Served page.

Frequently Asked Questions

What should I look for when hiring a commercial cleaning company?

Focus on five things: verified insurance, an in-house team, a site visit before the quote, clear quality control measures, and a contract that spells out the scope in writing. Commercial cleaning companies that can answer questions about all five specifically tend to be more reliable than those that offer only vague assurances about quality or professionalism.

What questions should I ask a janitorial company before signing a contract?

Ask whether team members are in-house or subcontracted. Ask for proof of insurance and bonding. Ask how quality is verified after the work is done. Ask who your day-to-day point of contact will be and how quickly they respond to issues. Ask what happens if a scheduled visit is missed or a task is done incorrectly. The answers will tell you more than a company brochure.

How do I know if a janitorial company is properly insured?

Ask for a certificate of insurance that shows general liability and workers' compensation coverage. The certificate should list your business as an additional insured if your lease or building requirements call for it. If you have any doubt about whether the policy is current, contact the insurance provider listed on the certificate directly to confirm.

Is it better to hire a local cleaning company or a national chain?

Both can work, but local companies often have practical advantages in responsiveness, flexibility, and direct management involvement. When a problem comes up, a local owner-operated janitorial service is more likely to respond quickly and personally. National or regional chains route issues through management layers that can slow resolution. Either way, hold any vendor to the same evaluation criteria.

How should I compare quotes from multiple janitorial companies?

Don't compare price alone. Compare scope. Two quotes at different price points may include very different levels of cleaning service. Read each proposal carefully for what is included, what is excluded, and what triggers additional charges. Ask each vendor what their quote assumes about frequency, hours, and coverage areas. A lower number that excludes key tasks isn't actually a lower price.
