Red Flags to Avoid

Watch out for these warning signs when evaluating commercial cleaning vendors.

No Insurance Certificates

Legitimate vendors provide insurance certificates immediately upon request. Hesitation suggests coverage issues.

Significantly Lower Price

Prices 30%+ below competitors often indicate corners being cut on labor, supplies, or insurance.

No Site Visit

Vendors who quote without seeing your facility will likely have pricing issues or scope disputes later.

Vague Contract Terms

Unclear scope of work, pricing, or exit clauses are warning signs of future disputes.

High Employee Turnover

Turnover above 100% annually indicates management issues that will affect service consistency.

No References

Inability to provide references from similar clients suggests lack of relevant experience.

Hiring a Commercial Cleaning Company: FAQs

How do I know if a commercial cleaning company is reputable?

Look for: proper insurance (GL, WC, umbrella), industry certifications (ISSA CIMS, Green Seal), at least 3-5 years in business, positive references from similar facilities, and responsive communication during the sales process.

Should I always choose the lowest bidder?

No. The lowest bid often results in service issues, scope disputes, or vendor turnover. Focus on value—competitive pricing from a qualified vendor with strong references and clear communication.

What insurance coverage should a cleaning company have?

At minimum: $1M general liability, $1M workers' compensation, and $1M umbrella coverage. Larger facilities may require higher limits. Always verify certificates are current before signing.

How long should a cleaning contract be?

Most commercial cleaning contracts are 1-3 years with annual renewal options. Avoid contracts longer than 3 years without favorable exit clauses, as your needs may change.

What should be included in a cleaning contract?

Essential elements: detailed scope of work, pricing and payment terms, performance standards, communication procedures, insurance requirements, termination clauses, and dispute resolution process.

When should I replace my current cleaning vendor?

Consider switching if: consistent quality issues aren't resolved, communication has broken down, pricing has increased significantly without justification, or the vendor can't meet evolving requirements.
