Key takeaways
- Verify before you trust: a DC business license number and current insurance certificates are the minimum bar — both can be independently checked in minutes.
- Ask all 12 questions on every walkthrough; how a company answers tells you as much as what it answers.
- An unusually cheap bid is a warning, not a win — janitorial pricing is mostly labor, so deep discounts come out of hours or insurance.
- Insist on a written, task-level scope of work and a 30-day termination clause.
- Score every bidder on the same worksheet so the decision is evidence, not a sales impression.
Why This Choice Carries Real Risk
Hiring a janitorial company is not like buying office supplies. You are giving an outside crew after-hours access to your space — keys, alarm codes, sometimes proximity to confidential files and server rooms — and taking on their risk profile as your own. If their cleaner is uninsured and gets hurt in your stairwell, if their unbonded employee walks out with a laptop, or if their "company" is actually a broker subcontracting to people they've never met, the consequences land on you.
Washington adds its own layers: federal contractors and law firms with security requirements, historic buildings in Georgetown with finishes that punish careless crews, and a dense market where anyone with a vacuum and a website can bid on commercial cleaning work. The good news is that the professionals are easy to identify — if you know what to ask and what to verify. This guide gives you both, plus a worksheet to keep the comparison honest.
The 12 Questions to Ask Every Bidder
Ask these during the walkthrough, in front of the person who would own your account. Take notes — you'll use them in the scoring worksheet at the end.
1. What is your DC business license number?
Every legitimate cleaning company operating in the District holds a DC business license — and a professional one will give you the number in writing without hesitation the moment you ask. If the answer is vague ("we're registered, don't worry"), end the conversation. The license number is also your key to independent verification, covered below.
2. Can you send current certificates of insurance?
You want proof of general liability insurance and workers' compensation coverage, issued by the insurer (a COI), not a screenshot or a verbal assurance. Without workers' comp, an injury in your building can become your liability. Ask to be named as a certificate holder so you're notified if the policy lapses mid-contract.
3. Are your employees bonded?
A janitorial (fidelity) bond protects you against theft by cleaning staff — crews work in your space after hours, often with keys and alarm codes. Bonding is inexpensive for the contractor, so a company that skips it is signaling how it thinks about risk.
4. Do you run background checks on every cleaner?
Not just "key staff" — everyone who enters your building. Ask what the check covers (criminal history, identity, work authorization) and whether it is repeated for new hires assigned to your account later. For government contractors and law firms this is non-negotiable.
5. How are your cleaners trained?
Listen for specifics: chemical handling and dilution, color-coded cloths to prevent cross-contamination, bloodborne-pathogen and OSHA safety training, and building-specific checklists. "We hire experienced people" is not a training program.
6. Who supervises the work, and how is quality checked?
The difference between a good first month and a good third year is supervision. Ask whether a supervisor inspects your site, how often, against what checklist, and whether you see the inspection results. Companies with real QC will describe a system; companies without one will describe good intentions.
7. Can you provide references in my building type?
Cleaning a medical suite, a restaurant, and a historic Georgetown office are different jobs. References from facilities like yours prove the company has already solved your specific problems — and gives you someone unaffiliated to call.
8. What green cleaning certifications or practices do you follow?
If indoor air quality, LEED requirements, or tenant expectations matter to you, ask what products and equipment they actually use — EPA-recognized products, HEPA-filter vacuums, microfiber systems — not just whether a "green option" exists at extra cost. Our guide to green cleaning for DC offices covers what to look for.
9. What happens when we have an emergency?
Pipes burst, events run long, a storm floods a lobby. Ask whether the company offers emergency response, what the realistic response time is, and what it costs. A provider with 24/7 capability is also telling you it has depth of staffing.
10. What are your contract terms — and how do I leave?
Read the term length, termination notice, price-escalation clauses, and auto-renewal language before signing. The fair standard in the DC market is a 30-day out. A company that resists a termination clause is planning to keep you by contract rather than by performance.
11. Who do I contact when something goes wrong — and how fast do you respond?
You want one named account contact, a defined response window, and a channel that creates a record (email or a ticketing system, not just the crew's cell phone). Ask how a missed task is handled: the right answer involves a documented re-clean, not a discount negotiation.
12. How is your pricing structured?
Fixed monthly price, per-square-foot, or hourly — each is legitimate, but you need to know which you're signing and what it includes. Ask what consumables (liners, paper, soap) cost, what counts as "extra," and how price changes are handled. A trustworthy quote itemizes; a risky one is a single round number.
On question 8, the specifics matter more than the label — see our green cleaning guide for DC offices for what genuine green programs include. And on question 12, our breakdown of commercial cleaning costs in DC explains what each pricing model typically covers, so you can compare quotes line by line.
Red Flags That Should End the Conversation
Most bad outcomes with cleaning vendors were predictable at the proposal stage. These are the warning signs we'd treat as disqualifying:
| Red flag | Why it matters |
|---|---|
| Refuses or stalls when asked for a license number | Either unlicensed or hiding something. Verifiable companies hand over their number immediately because it wins business. |
| Won't produce insurance certificates | If a cleaner is injured or property is damaged, an uninsured contractor's problem becomes your problem. No COI, no contract. |
| Vague scope of work ("full cleaning, weekly") | Undefined scope means every future dispute defaults against you. Demand a task-by-task, frequency-by-frequency scope in writing. |
| Door-to-door or high-pressure sales tactics | "Sign today for this price" is how companies without references sell. A real commercial provider expects you to compare bids. |
| Price dramatically below other quotes | Janitorial costs are mostly labor. A too-good price means under-staffed visits, uninsured workers, or a low-ball intro rate that climbs later. |
| No physical local address or local phone number | Lead-generation brokers resell your contract to unknown subcontractors. You should know exactly who is in your building. |
| Cash-only payment or no written agreement | No paper trail means no accountability — and often no tax compliance, insurance, or workers' comp behind the crew. |
None of these are "negotiate harder" items. A vendor who fails on licensing, insurance, or scope clarity at the sales stage — when they are on best behavior — will not improve once the contract is signed.

How to Verify a DC Business License and Insurance
Verification takes about ten minutes and is the highest-value step in this entire process. Here's how to do it in the District:
Step 1 — Get the license number in writing
Ask each bidder for their DC business license number and write down the exact company name it's issued under (which should match the name on the contract — a mismatch is its own red flag). Professional companies make this easy. As a worked example, TotalMGT is DC Business Licensed and provides the license number in writing with every quote, and proposals, so a prospective client never has to ask twice.
Step 2 — Check it with the DC licensing authority
DC business licenses are issued by the District's Department of Licensing and Consumer Protection (DLCP), and license records are public. Search the company name or license number through DLCP's online business license verification tools, and confirm three things: the license exists, it is active (not expired or revoked), and the legal name and address match what the company gave you. If you can't find the record, call DLCP directly rather than taking the vendor's word for it.
Step 3 — Demand certificates of insurance, from the insurer
Ask for a certificate of insurance (COI) for general liability and a separate confirmation of workers' compensation coverage. The COI should be issued by the insurance carrier or broker — ideally sent to you directly — and show current policy dates and coverage limits. Check that the named insured matches the contracting company, and ask to be listed as a certificate holder so you're notified of cancellation. TotalMGT, for its part, is fully licensed, bonded & insured and provides proof of insurance on request — treat that as the baseline any bidder must meet, not a bonus.
Step 4 — Cross-check the company's footprint
Five more minutes of diligence: confirm the physical address is real, the phone number is answered professionally, and the company has a visible review history. A provider that has served buildings from downtown DC to the suburbs for years will have an easily traceable footprint; a broker or fly-by-night operation won't.
The Scoring Worksheet
After two or three walkthroughs, sales impressions blur together. This worksheet keeps the decision factual. Score each bidder from 1 (poor/unverified) to 5 (excellent/verified) on every criterion, multiply by the weight, and total it. The weights reflect risk: licensing, insurance, supervision, and references protect you the most, so they count the most.
| Criterion | Weight | Score (1–5) | Weighted |
|---|---|---|---|
| License verified with DC DLCP | ×10 | ____ | ____ |
| Insurance certificates provided (GL + workers' comp) | ×10 | ____ | ____ |
| Employees bonded | ×8 | ____ | ____ |
| Background checks on all staff | ×8 | ____ | ____ |
| Documented training program | ×7 | ____ | ____ |
| Supervision & QC inspection system | ×9 | ____ | ____ |
| References in your building type (called, positive) | ×9 | ____ | ____ |
| Green certifications / practices | ×5 | ____ | ____ |
| Emergency response capability | ×6 | ____ | ____ |
| Fair contract terms (30-day out, no traps) | ×8 | ____ | ____ |
| Named contact & response-time commitment | ×8 | ____ | ____ |
| Transparent, itemized pricing | ×8 | ____ | ____ |
| Total (maximum 480) | ____ | ||
A practical reading of the totals: anything under ~300 means meaningful gaps in protection or accountability; 300–380 is a workable vendor worth negotiating with; above 380 is a genuinely professional operation. Hard rule regardless of total: a score of 1 on license verification or insurance is disqualifying on its own.

Frequently Asked Questions
How many janitorial quotes should I get before deciding?
Three is the practical sweet spot. Fewer than three and you have no real price baseline; more than five and the walkthroughs consume more of your time than the decision is worth. Make sure every bidder quotes the same written scope so the numbers are comparable.
Should I always choose the lowest janitorial bid?
No — in janitorial services, an unusually low bid is itself a red flag. Labor is the dominant cost, so a price far below the other quotes usually means fewer cleaning hours than the scope requires, under-insured operations, or misclassified workers. Choose the best-scoring company within your budget, not the cheapest number.
Is TotalMGT licensed and insured?
Yes. TotalMGT operates under DC Business Licensed, is fully bonded and insured, and provides certificates of insurance on request. Staff are background-checked, and the company is EPA green-cleaning certified and OSHA safety compliant.
What contract terms are normal for commercial cleaning in DC?
Month-to-month agreements or annual contracts with a 30-day termination clause are both common and reasonable. Be cautious with multi-year terms that lack an exit clause, automatic renewals with long notice windows, or steep early-termination fees — a confident provider doesn’t need to lock you in.
How do I check a cleaning company’s references properly?
Ask for two or three current clients in your building type and call them with specific questions: How long have they used the company? Has the crew stayed consistent? How were problems handled? Would they re-sign today? A reference who hesitates on the last question tells you more than any brochure.
