Sanitizing services remain one of the most accessible add-ons for exterior cleaning contractors. Every time a business temporarily closes — whether for a positive test, a seasonal deep-clean, or a tenant turnover — someone has to sanitize the space before it reopens. If you already own a sprayer and a bucket, you're most of the way there.

The Opportunity in Re-Closings

When businesses shut down temporarily and need to sanitize before reopening, the work usually goes to whoever picks up the phone first. Contractors who've already done exterior work for a client — pressure washing, window cleaning, storefront maintenance — are the obvious call. The relationship is already there. You just need to let them know you offer interior sanitizing.

Napa Valley Steaming built exactly this pipeline. When commercial clients closed during the COVID-19 outbreak, the team let existing customers know sanitizing services were available. Two months later, a local winery — a past exterior cleaning client — called after an employee tested positive. The Napa Valley Steaming crew sanitized the entire interior. In a tourist-heavy market, businesses were eager to reopen fast, and sanitizing was the bottleneck they needed solved.

The lesson: don't wait for inbound calls. Reach out to every commercial client on your list and tell them you handle sanitizing. Most won't need it today, but when they do, you'll be the contractor they remember.

Sanitizing Made Simple

You don't need a dedicated rig. A gallon of ProTool Clean & Shine dilutes to 64 gallons of ready-to-use disinfectant. Add it to your window cleaning bucket and you can sanitize glass, counters, and high-touch surfaces in a single pass. Wipe down door handles, railings, and point-of-sale areas with a microfiber towel dampened with the solution — that alone is a billable add-on most customers will pay for without hesitation.

For full-room interior sanitizing, pair Clean & Shine with a chemical-resistant pump sprayer or a backpack sprayer to cover larger spaces efficiently. Mist walls, ceilings, and soft surfaces, then wipe high-touch points by hand. The two-step approach — spray the room, hand-wipe the contact surfaces — is fast, thorough, and easy to explain to a property manager.

Pricing and Positioning

Sanitizing is high-margin work. The chemical cost per job is negligible — a single gallon of concentrate covers dozens of service calls. Price it as a standalone service (square-footage-based) or as a per-visit add-on to your regular cleaning route. Either way, the labor is light and the perceived value to the customer is high.

Position it as a business continuity service, not a janitorial task. You're helping them reopen faster, protect their staff, and signal to their own customers that the space is safe. That framing justifies a premium over basic cleaning rates.
