Signing a janitorial services contract for your Metro Detroit building is a commitment. You're handing over keys, alarm codes, and after-hours access to people who will be in your space when nobody else is around. A bad fit shows up fast: missed tasks, unfamiliar faces, and a phone number that rings to voicemail.
This guide walks through the verification steps we recommend before you sign with any commercial cleaning company in Wayne, Oakland, or Macomb County. CJT Janitorial is happy to be held to every one of these steps, and we think you should hold every vendor to the same standard.
Ask for a current certificate of insurance before your first meeting. The certificate should list general liability coverage and workers' compensation. A legitimate local cleaning partner will send this documentation promptly when you request it, and you should be named as an additional insured on the policy if your lease requires it.
Verification goes one step further. Call the insurance carrier listed on the certificate and confirm the policy is active and the coverage limits match what the vendor stated. Policies can lapse between renewals, and a certificate issued months ago may not reflect the current status. CJT Janitorial keeps an insurance certificate available on request and encourages buyers to verify directly with the carrier.
The crew that cleans your building should be consistent, screened, and employed by the company you hired. Ask whether the vendor uses direct employees or subcontractors. Subcontracting is common in commercial cleaning, but it changes who controls training, scheduling, and accountability for the people entering your space after hours.
Ask these specific questions during your evaluation:
A company that assigns a consistent, vetted crew to your building reduces security risk and builds familiarity with your space. That crew learns the layout, the trouble spots, and the things your tenants or patients notice first.
Cleaning happens after hours. You won't be watching. That makes the vendor's inspection process one of the most important factors in your decision. A janitorial company worth signing should be able to describe exactly how work gets checked, how often, and what happens when something falls short.
Ask for specifics:
CJT Janitorial assigns a named point of contact to every account and works from the documented scope. If something is missed, we want to hear about it the same day so we can address it before your next business morning.
A written, facility-specific scope defines every task, frequency, service window, and price before work begins. It removes ambiguity about what's included in the base contract and what costs extra. Without it, disputes over "I thought that was included" become inevitable.
Your scope document should cover:
CJT Janitorial builds every proposal around a free walkthrough of your space. We document the tasks, frequencies, assumptions, and exclusions before quoting a fixed monthly price. You can review our scoping and verification process for a closer look at how that works.
Ask for a few references from current clients with spaces similar to yours. A medical clinic and a warehouse have different cleaning needs, so references from your facility type carry more weight. A company that is confident in its track record will hand over names and phone numbers without hesitation.
When you call references, focus on these points:
Online reviews add another data point, but direct conversations tell you more about day-to-day reliability. Pay attention to how the company handles complaints. That pattern predicts how they'll treat your account once the contract is signed.
Switching janitorial vendors affects your building's daily routine. A responsible vendor will map out the first month: crew introductions, key and alarm handoff, a walkthrough of high-priority areas, and a review of documented expectations before the first scheduled cleaning.
A clear transition plan should include:
If a vendor can't describe their transition process, that's a signal. The first month sets the tone for the entire relationship. CJT Janitorial confirms access, scope, crew assignment, and your named point of contact in writing before the first visit of any office cleaning or medical facility cleaning program.
A shorter initial term with month-to-month renewal is a reasonable starting point. Watch for multi-year auto-renewals with long cancellation windows. CJT Janitorial uses fixed monthly proposals with clear terms so you know exactly what you're paying and when.
Comparing a few proposals helps you evaluate scope differences, not just price. A lower number that excludes key tasks is not actually cheaper. Ask each vendor what their quote assumes about frequency, hours, and coverage areas. You can request a free walkthrough and quote from CJT Janitorial to see how a scoped proposal compares.
The terms overlap, but "janitorial" usually means recurring commercial work on a set schedule: restrooms, trash, vacuuming, surface cleaning. "Cleaning service" can cover one-time jobs, residential work, or specialty tasks like post-construction detail. CJT Janitorial handles recurring janitorial programs as well as post-construction and other project cleans across Metro Detroit.
A vendor quoting without seeing your building is working from assumptions. Square footage, restroom count, flooring type, and traffic patterns all affect the scope and price. CJT Janitorial starts every new relationship with a free walkthrough so the proposal matches the actual space and priorities.
Ask directly: who owns the business, and will that person be involved in managing your account? A locally owned, owner-run operation gives you a direct line to the person accountable for your service area. CJT Janitorial is owner-run and based in Royal Oak, MI, serving Wayne, Oakland, and Macomb counties.
