Most commercial mold calls in Spokane start with water nobody saw for a while: a roof leak above a drop ceiling, a sprinkler line or water heater in a back room, a rental with a bathroom fan that never ran, or a loading dock where snowmelt collects against the wall every spring. By the time someone notices the smell or the stained ceiling tile, the job usually covers more than one room.
What changes on a commercial job
The steps are the same as in a house. The company finds the moisture source, sets up containment, removes materials that can’t be cleaned, cleans and dries what stays, and checks that the area is dry and clear before it’s rebuilt. What changes is everything around that:
| On a commercial job | What to ask the company |
|---|---|
| People in the building | How they’ll seal off the work area and keep air from moving through the HVAC |
| Business hours | Whether they can work nights or weekends, and in phases |
| Multiple units or floors | How they’ll scope each area and track progress |
| Records | What photos, moisture readings and reports you’ll get at the end |
| Insurance | Whether they’ll provide a written scope your adjuster can use |
| Sign-off | Who does clearance testing, and whether it’s an independent firm |
Rentals and multi-unit buildings
Landlords and property managers see a lot of mold that starts with tenant habits nobody can control: showers with no fan running, humidifiers, drying laundry indoors through a Spokane winter. Fixing the ventilation matters as much as the cleanup, or the same unit calls again next year. Ask the company what they’d change so it doesn’t come back.
Before you call
Write down which rooms or units are affected, when the problem was noticed, whether water is still getting in, and whether people are working or living in the space. Photos help. If you already have a test report or an insurer involved, mention that on the form too.
