When you request a quote for commercial cleaning, you aren’t just looking for a price tag—you are looking for a plan. A vague, one-page bid that says “we clean everything” is usually a red flag. A professional proposal should be a roadmap that proves the company understands the unique footprint of your building.

At Optimal Prime Cleaning Services, we believe a well-constructed proposal is the foundation of a long-term partnership. Whether you are shopping around or refining your current setup, here is what you should look for in a professional janitorial proposal and how to ensure your checklist covers all the bases.
1. The Scope of Work (The “What”)
A good proposal doesn’t use generic terms. It should break down your facility by zone. Look for a document that separates tasks by area, such as:
- Entrance & Lobby: First impressions matter. Is there a focus on glass partitions and floor mats?
- Workstations & Offices: Does the plan include high-touch disinfection for phones and keyboards, or just a quick dust?
- Restrooms: This is the most critical area. The proposal should detail specific sanitation protocols, not just “cleaning the toilet.”
- Kitchen/Breakroom: Look for mentions of sink scrubbing and exterior appliance wiping.
2. Frequency and Scheduling (The “When”)
Consistency is the enemy of grime. A solid proposal will clearly define:
- Daily Tasks: Emptying trash, restroom sanitation, and high-touch point disinfection.
- Weekly/Monthly Tasks: High dusting (vents, ceiling fans), baseboard cleaning, or window ledges.
- Periodic Special Services: Many companies (like Optimal Prime) include options for carpet extraction or hard floor stripping and waxing. These should be scheduled so they don’t catch you by surprise.
3. Proof of Training and Accountability (The “How”)
A proposal is only as good as the person holding the mop. Look for a section that explains how the company ensures quality. At Optimal Prime, we use digital checklists and GPS-verified clock-ins to ensure our team stays accountable to the plan we built for you.
- Ask: “How do I know if a task was missed?”
- The Answer should be: “Through documented inspections and clear communication channels.”
4. Supplies and Equipment
Does the company bring their own chemicals? Are they using commercial-grade HEPA vacuums that actually improve your indoor air quality? The proposal should mention the types of products being used in your space, especially if you have specific requirements for “green” cleaning or medical-grade disinfectants.
Building Your Own Checklist: A Quick Guide
If you are developing a checklist to hand to potential cleaners, focus on these “Problem Areas” that often get overlooked in Sioux Falls offices:
- Touch Points: Light switches, elevator buttons, and door handles.
- Vertical Surfaces: Fingerprints on glass doors and smudges on cabinets.
- Under the Surface: Vacuuming under desks, not just around them.
- The “Invisible” Areas: Dusting the tops of monitors, vents, and picture frames.
Why the Proposal Matters
A cheap bid often hides a lack of detail. When a company takes the time to measure your square footage, count your restrooms, and ask about your “pain points,” they are building a proposal that prevents the “honeymoon phase” from ending.
In Sioux Falls, we deal with salt and slush in the winter and dust in the summer. Your cleaning proposal should reflect those seasonal realities.
