How to Choose a Hood Cleaning Company: Questions to Ask Before You Hire
October 12, 2026 | 6 min read
Hiring someone to clean your kitchen exhaust means letting a crew into your kitchen, onto your roof and into the part of your building where grease collects. Because you, not the cleaning company, are ultimately responsible for the system, it is worth asking good questions before you choose. This list works with any provider you are considering.
Ask about scope
- Does the quote include the hood, filters, plenum, duct and rooftop fan?
- What happens if parts of the duct cannot be reached because there are no access panels?
- How will they handle the rooftop fan and grease containment?
- Are there extra charges for after-hours work, heavy buildup or additional access panels?
Ask about process
- How do they protect equipment, floors and surfaces near the hood?
- How do they contain and remove wash water and debris?
- How long is the visit likely to take and how many people will come?
- How do they decide whether the system is clean when they finish?
Ask about scheduling
- Can they work outside your service hours?
- How do they handle weather that makes the roof unsafe?
- Do they offer recurring plans, and how are reminders handled?
Ask about records
Your inspector and your insurer may ask for proof of cleaning. Ask what you get after each visit: a written service report, photos, a note about areas that could not be reached and a dated record you can keep. Ask whether a service sticker is applied and what it says.
Ask about insurance and credentials, then verify
Ask any provider whether they carry insurance for the work, and request a certificate you can check with the issuer. Ask whether they hold any licenses or certifications that your landlord, property manager or insurer require, and whether they can provide proof. Do not rely on a logo or a claim on a website; ask for documentation and confirm that it is current. Denver has its own licensing for certain fire protection work, so ask your fire department which activities require it.
Ask about suppression systems
Hood cleaning and wet-chemical suppression system inspection are different services with different licensing. If you need both, ask whether the company performs both or coordinates with another company, and who is responsible for each part.
Watch for red flags
- A price quoted without seeing the system or asking about your cooking.
- A promise that you will pass an inspection.
- No written report or no records after the visit.
- Vague answers about insurance, scope or how the duct will be cleaned.
- Pressure to sign immediately or pay in full in advance.
Compare like with like
Put each quote next to the others and check that they cover the same parts of the system, the same hours and the same documentation. A quote that looks cheaper may leave something out. Once you have chosen, start with a walk-through, agree the schedule and keep every report.
