Start With a Commercial Cleaning Proposal Checklist

Knowing how to evaluate commercial cleaning service providers starts with one document: the proposal. A proposal is the written offer a cleaning company submits before you sign. It should tell you exactly what gets cleaned, how often, and who is accountable.

At A Smarter Clean, we've reviewed enough bids to know that most proposals are too vague to compare. A short checklist fixes that:

• Building address and square footage listed
• Task list by room or area
• Frequency for each task
• Supplies and equipment included
• Floor care listed separately
• Start date and contract term
• Insurance and contact details attached

If a proposal skips any of these, ask for it in writing. A company that won't put details on paper now won't deliver them later.

Questions to Ask a Commercial Cleaning Company Before You Sign

Ask direct questions, and listen for direct answers. The U.S. Small Business Administration guide to choosing a vendor recommends checking references and getting everything in writing before signing. That advice applies here too.

Here are the questions we hear most from facility managers, and what a good answer sounds like:

• Who cleans our building? You want named supervisors and consistent crews, not a rotating cast.
• How do you handle callouts? A clear backup plan beats a promise.
• What's your quality check process? Look for scheduled inspections, not "we just know."
• Can you handle floor care ? Ask about VCT stripping and waxing, scrub-and-recoat, and burnishing.
• What does the contract cover? Extra charges should be spelled out, not sprung on you.

Demand a Clear Janitorial Services Scope of Work

A janitorial services scope of work is the written list of tasks, frequencies, and standards that defines the job. It is the single most important part of any cleaning contract. Without it, "clean" means whatever the crew decides that day.

A strong scope of work covers:

• Daily tasks: trash, restrooms, spot mopping, vacuuming high-traffic areas
• Weekly and monthly tasks: dusting high surfaces, deep restroom detail, floor buffing
• Periodic tasks: carpet cleaning, tile and grout cleaning, floor stripping and waxing
• Standards: what "done" looks like for each area
• Exclusions: what is not included, so there are no surprises

Medical and dental offices need extra attention to restroom and touch-point cleaning. Spell that out. Schools and churches need gym and hallway floors on a set schedule. Banks need lobby glass and entry areas on a reliable rhythm. The scope should match your building, not a generic template.

How to Judge Reliability and Communication

Reliability shows up in small habits: crews arriving on schedule, the same supervisor answering the phone, and problems fixed without three follow-up emails. You can't test that in a sales meeting, so test it before you sign.

Try these steps:

1. Call the company's main line during business hours and time the response.
2. Ask how they report issues and who receives complaints.
3. Request a sample inspection report.
4. Ask what happens when a crew member calls out sick.

A dependable provider answers these without hesitation. A weak one promises "great communication" and gives you no process behind it.

Build a Commercial Floor Maintenance Program Into the Contract

Floors are where cheap cleaning contracts fall apart. A commercial floor maintenance program is a scheduled plan for protecting hard floors and carpet over time, not just reacting when they look bad. Build it into the contract from day one.

Here is what a solid program covers:

Ask the provider to explain each service in plain terms. Stripping removes old finish and wax; recoating adds a fresh layer; burnishing polishes the surface between recoats. LVT/LVP needs different care than VCT, and a provider who treats them the same will dull your floors.

At A Smarter Clean, our recurring floor care covers VCT stripping and waxing, scrub-and-recoat, burnishing, LVT/LVP maintenance, low-moisture carpet cleaning, and tile and grout cleaning. We build these into a scheduled program so floors stay protected instead of being rescued after damage sets in.

Verify Insurance, References, and Quality Control

Insurance and references are your safety net. Ask for a certificate of insurance before work starts, and confirm it names general liability coverage. Then call two or three current clients with buildings like yours.

The Occupational Safety and Health Administration publishes guidance on chemical safety and hazard communication in the workplace. Ask which products the company uses and whether safety data sheets are available for your files. A provider that uses OSHA-safe products should be able to show you the documentation without delay.

Quality control is the third leg. Ask:

• How often are inspections done, and by whom?
• Do you share written reports?
• How are complaints tracked and closed out?
• Can we walk the building together on a set schedule?

Conclusion: Choose Commercial Cleaning Providers Who Prove Their Process

The hardest part of hiring a cleaning company is trusting that the service you're promised is the service you'll get. The fix is simple: make providers prove their process before you sign. A detailed proposal, a clear janitorial services scope of work, a real floor maintenance plan, and verifiable insurance and references separate serious providers from sales pitches.

That's how we built A Smarter Clean. We offer flexible nightly, weekly, or monthly janitorial programs, low-moisture carpet cleaning, and scheduled floor care across Delaware and Maryland's Eastern Shore. We put our scope of work in writing and stand behind it with responsive communication and dependable crews.
