Why Choosing a Medical Cleaning Service Is Different
The process of choosing a cleaning service for a medical office is different from choosing one for a standard commercial space. The stakes are higher — an infection control failure in a clinical environment has consequences that a missed surface in a law office does not. The documentation requirements are more specific — accreditation bodies, licensing agencies, and facility management companies may all require evidence of the cleaning service's insurance, products, and protocols. And the cost of switching mid-contract is higher — crew turnover creates relearning time that shows up in cleaning quality before it shows up anywhere else.
These five questions filter out the contractors who have never cleaned a clinical space from the ones who have.
Question 1: Do you provide a written scope of work?
This is the first filter. A written scope of work lists specific surfaces, products, frequencies, and sequences. A contractor who cannot or will not provide one before service begins is offering a cleaning arrangement, not a cleaning contract. The scope protects both parties — you can point to it when something is missed, and the contractor can use it to train replacement crew without quality loss.
What to look for in the scope: surface-level specificity (not "clean the exam rooms" but "exam table surface, pillow covers, instrument tray, door hardware, light switch, sink and faucet, soap and towel dispensers, floor"), product names or EPA registration categories, and explicit statements about what is not within scope (instrument processing, clinical waste).
Question 2: What disinfectants do you use, and are they appropriate for healthcare settings?
The contractor should be able to name specific products or product categories and explain why they are appropriate for clinical surfaces. EPA List N disinfectants registered for healthcare use are the standard. A contractor who is unfamiliar with EPA List N, or who proposes general-purpose cleaners for clinical surfaces, is not operating at clinical standard.
Follow-up: do you adjust products based on surface material? Dental chair upholstery, rubber flooring, and stainless steel all have different product compatibility requirements. A contractor who uses the same product on all surfaces without consideration of material is missing this.
Question 3: Do you carry liability insurance and workers' compensation, and will you provide a certificate?
The answer should be yes and the certificate should be available immediately, not promised for a future date. Verify that the coverage is current and that it covers the type of facility you are operating. If your facility management company, building lease, or accreditation standards require specific coverage levels or additional insured endorsements, ask about those specifically before the conversation goes further.
Question 4: Will the same crew clean our facility each time?
This is where most general commercial cleaning services struggle. High crew turnover means the learning curve repeats itself every few visits, and the quality floor resets each time. A contractor who commits to consistent crew assignment — and introduces new crew members to facility management before independent deployment — is operating at a level above the commodity cleaning market.
Question 5: How do you handle issues that arise between scheduled visits?
The answer should identify a specific person, not a process. "You contact your account lead directly" is an answer. "You call our customer service line and we will follow up within 48 hours" is a warning sign. In a clinical environment, a cleaning issue may need to be addressed before the next patient arrives, not the next business day.
After the Questions
A contractor who answers all five questions well — specific scope, named products, insurance available, consistent crew, direct contact for issues — is operating at clinical standard. Get the scope in writing before service begins, confirm the insurance certificate is on file, and schedule a 30-day review to assess performance before committing to a longer term.
