Step-by-step selection
How to Choose a Commercial Cleaning Company
A seven-step process for selecting a commercial cleaner, from writing down what the building needs to the first month of service, with what to do at each step.

The short answer
How to choose a commercial cleaning company comes down to a fixed sequence: define the scope your building needs, build a shortlist of qualified firms, walk each one through the site, compare proposals line by line against the same scope, verify references and documents, negotiate the contract, and plan the startup. Running every bidder through the same steps keeps the comparison fair and puts the decision on evidence instead of on the most polished presentation.
How to choose a commercial cleaning company: the seven steps
Each step produces something the next one depends on. Skipping the first, writing down the scope, is the most common reason bids cannot be compared later.
| Step | What you do | What you get |
|---|---|---|
| 1. Define the scope | List areas, tasks, frequencies, hours and access rules | One document every bidder prices |
| 2. Build a shortlist | Pick three to five firms from referrals and peers | Only qualified bidders |
| 3. Run the site walk | Same route and information for every bidder | Proposals that line up |
| 4. Compare proposals | Check each one line by line against your scope | Real differences in price and staffing |
| 5. Verify | Call references, collect insurance and registration | Evidence behind the claims |
| 6. Negotiate the contract | Scope, service levels, pricing terms, notice | Terms you can enforce |
| 7. Plan the startup | Keys, orientation, deep clean, baseline inspection | A steady first month |
Steps 1 and 2: define what you need, then shortlist
Start with the building, not the vendors. Gather cleanable square footage, floor types, restroom fixture counts, occupancy, operating hours, security and key rules, and any special areas such as labs, server rooms or medical suites. Then list tasks by area and frequency, and decide who supplies paper, soap and liners. Two pages written by you will produce better proposals than asking each bidder what they recommend, because otherwise every company prices a different job.
With the scope in hand, build a shortlist of three to five firms. Screen for your service area, experience with your building type, a company size that fits your account, and current registration and insurance. Our factors post covers how to weigh those criteria.
Step 3: run one site walk for everyone
Give every bidder the same tour, the same documents and the same deadline. Show the hard parts: the busiest restrooms, the kitchen, worn floors, loading areas and any space with special rules. Answer questions in writing and share the answers with all bidders so nobody prices on private information.

Step 4: compare proposals line by line
Lay the proposals side by side against your scope. The price at the bottom matters less than what produced it. A bid that is far lower than the rest usually assumes fewer labor hours, which means less cleaning, whatever the proposal says. Ask each company to state its hours and staffing so you can see the difference directly. Line these items up across every proposal:
- Labor hours or staff assigned per shift
- Task frequencies compared with your scope
- Periodic work included, such as floor care, carpet and glass
- Supplies and consumables: included, billed separately or yours
- Supervision: who, how often and how inspections are recorded
- Exclusions and anything priced as an extra
Steps 5 and 6: verify, then negotiate the contract
Before choosing, call references at comparable buildings, collect certificates of insurance and confirm the company's janitorial registration with the state. Our post on reliable cleaning companies lists the questions that get past polite answers.
Then put the agreement in writing. Attach your scope as an exhibit, define how inspections will be scored, set how and when pricing can change, name who supplies consumables, state the insurance you require and agree on a notice period. California has specific rules for janitorial changeovers, so ask the new contractor how it will handle the transition from your current crew.
Step 7: plan the startup
A good selection can still stumble in the first weeks. Agree on the start date, collect and reissue keys and badges, and give the new crew a full orientation covering alarm codes, restricted areas and tenant preferences. Schedule an initial deep clean if the building needs one, then walk the building together to set a baseline. Review the record at 30, 60 and 90 days so small problems are fixed before they become habits.
What the process looks like with EBS
When you include EBS Maintenance in your shortlist, a supervisor visits the site, notes traffic, surfaces and access rules, and listens to what is and is not working today. What comes back is a scope, schedule and price written for that building alone, and EBS does not bill for the site visit or for preparing that proposal. After startup, supervisors stay in contact and inspections are logged in eHub. Call (949) 375-3305 to schedule a visit.

Request a walkthroughAll questionsHow many cleaning companies should we ask to bid?
Three to five is a practical range. Fewer than three gives you little to compare, and more than five makes the site walk and review hard to manage and discourages good bidders, who know their odds are low. Shortlist carefully before inviting anyone.
How long does it take to select a commercial cleaner?
Plan on several weeks. Writing the scope, running site walks, waiting for proposals, checking references and negotiating each take time, and the new contractor needs time to hire and train before starting. Allow for your current contract's notice period as well.
Should we choose the lowest bid?
Only if it prices the same scope with comparable labor hours and supervision. When one bid is much lower, ask how it will be staffed. Lower hours almost always mean tasks done less often or less thoroughly, which tends to show up within a few months.
