The opening

Why this idea is overlooked

Everyone pictures residential cleaning; commercial contracts pay monthly, renew for years, and are won with a professional bid, not a flyer.

The roadmap

How to start, step by step

  1. 1

    Pick a building type to own

    Small offices, medical suites, gyms, or churches. Medical pays more but expects bloodborne pathogen training; start where you can win and specialize.

  2. 2

    Get insured and bonded

    General liability (around $500 to $1,000 a year) plus a janitorial bond. No facility manager signs a contract without seeing both certificates.

  3. 3

    Form the entity and set your rates

    Register an LLC, get an EIN, and price by the square foot or by monthly walkthrough estimate. Know your labor cost per hour so a $600 a month contract never costs you $700 to service.

  4. 4

    Build a professional bid package

    A one page scope of work, cleaning checklist, insurance certificates, and a monthly price. This is what separates you from the flyer-on-the-door crowd.

  5. 5

    Walk into twenty buildings

    Ask for the office or facility manager and offer a free walkthrough and written quote. Property management companies are the jackpot; one relationship can hand you five buildings.

  6. 6

    Nail the first ninety days

    Clean it yourself at first, do a weekly quality check with the client, and fix complaints same day. Commercial contracts renew on reliability, not price.

  7. 7

    Hire a crew and add buildings

    Once you have three contracts, hire and train your first cleaner, document the checklist per building, and go win the next three. Your job becomes bids and quality, not mopping.

Your first move

Get insured and bonded, then walk into twenty small offices and medical suites offering a free walkthrough and a written monthly quote.
