Mold Inspection In Cheney, WA

Cheney is a rental town. Eastern Washington University sits in the middle of it, the population roughly doubles when school is in session, and a large share of the housing near campus is not owner-occupied. That changes who calls us and why. In most of Spokane County the caller is a homeowner who found a stain. In Cheney it is just as often a landlord, a property manager, or a tenant who has already sent two emails and gotten nowhere.

We handle both sides the same way. We test, we document, and we hand over a report. We do not do remediation and we take no referral fee from anyone who does, which is the only reason a report from us is useful in a dispute. Base inspection is $425 including one indoor air sample plus an outdoor control. Cheney is inside our normal service area, so there is no trip fee.

What Washington law actually requires of a landlord

This comes up on nearly every Cheney call, so here it is plainly.

RCW 59.18.060 obligates a Washington landlord to maintain the premises in a habitable condition and to provide tenants with information about the health hazards of indoor mold. What it does not do is require testing. There is no statutory mold standard in Washington, no permissible spore count, and no state license for mold inspection or remediation. The Department of Health publishes guidance and nothing more.

The practical consequence is that mold testing in a rental is dispute-driven. Nobody has to test. People test when the two parties disagree about whether there is a problem, when a security deposit is contested, when a habitability claim is threatened, or when an owner wants documentation before or after a tenancy. A neutral third party with lab data ends most of those arguments faster than another round of emails.

For a property manager running a portfolio of Cheney units, the useful move is testing at turnover on the units that generate complaints, not testing everything. We will tell you honestly if a unit does not need it.

Cheney's specific moisture problems

Elevation and freeze cycles. Cheney sits around 2,350 feet, several hundred feet above downtown Spokane, and it is measurably colder and holds snow longer. More freeze and thaw cycles mean more ice dam events on the low-slope roofs common in older campus-area rentals, and more frozen pipe risk in unheated or under-heated units. Nationally, frozen pipes and cold weather damage make up roughly 7% of all insurance claims and burst pipes are the third costliest loss event in the country at about $1.4 billion a year.

Scabland geology and poor infiltration. The West Plains around Cheney are channeled scabland. Basalt sits close to the surface with thin soil over it, and there are kettle ponds and seasonal wetlands scattered through the area, most visibly out toward Turnbull National Wildlife Refuge. Thin soil over rock does not absorb spring melt well. Water sheets across the surface and pools against foundations, and older basements in the town core take it in through the wall or the cove joint.

Housing split into two very different populations. The older core near First Street and the blocks around campus holds 1900s to 1940s stock, full basements, original or partially updated plumbing, and many single-family homes that were carved into multiple rental units over the decades. Carved-up houses get bathrooms and kitchenettes installed into spaces that were never designed to be ventilated. The newer subdivisions north and west of town are 1990s onward, on crawlspaces and slabs, with entirely different failure modes centered on flashing, attic venting and appliance lines.

Summer vacancy. This one is specific to a college town. A student rental gets closed up in mid May and nobody opens a door until late August. Heat off or set low, no air movement, and any small leak that started in spring has three unobserved months to develop. We do a meaningful share of our Cheney work in August, right before move-in, and again in September when the first tenant complaint arrives.

High occupancy in small units. Four people in a two bedroom generate a lot of moisture. Showers, cooking, laundry and breathing. In a tight older unit with an inoperative or ducted-to-nowhere bath fan, interior humidity climbs and condensation forms on the coldest surfaces, usually north-facing exterior wall corners and behind furniture pushed against the wall. That surface growth is a ventilation problem, not a leak, and the fix is different. Knowing which one you have is the point of testing.

What happens during the visit

Most Cheney units take an hour or two. A full house divided into units takes longer because each unit needs its own readings.

• Psychrometric readings in each area and outdoors. Relative humidity, temperature and dew point. In a high-occupancy unit this often explains the whole complaint.
• Moisture mapping with pin and pinless meters on suspect walls, floors, subfloor and framing.
• Thermal imaging to find temperature differentials behind finished surfaces, including cold spots at uninsulated wall sections where condensation forms.
• Borescope into wall cavities and closed spaces where water may have traveled.
• Air sampling using a calibrated pump that draws a measured volume through an Air-O-Cell or Allergenco-D spore trap cassette. Cassettes go to an accredited lab for direct microscopic examination.
• Surface sampling by swab or tape lift when there is visible growth, which is how you establish whether the thing in the photo the tenant sent is actually mold.

Every job includes an outdoor control sample. Outdoor air always contains mold spores. An indoor count on its own means nothing, because there is no fixed number that counts as high. Elevated means elevated compared with outside, sampled the same day at the same address. If you are going to rely on a report in a deposit dispute or a habitability discussion, it needs that comparison in it or it will not hold up to a serious reading.

Pricing

Inspection base is $425 and includes one indoor air sample plus an outdoor control. Each additional sample is $100, so a typical three sample job runs about $525. Homes over 3,000 square feet are $550 to $650. Post remediation clearance for restoration contractors is $375 flat for up to three samples. Rush 24 hour lab turnaround adds $100.

No trip fee to Cheney. Lab results normally return in one to three business days, with the written report within a day of that.

For managers with multiple units, tell us what you have and when you need it and we will schedule them together.

Independence is the entire point

Every mold company in this market that also sells remediation has a financial interest in finding mold. That is not an accusation, it is arithmetic. New York made the arrangement illegal under Labor Law Article 32, which bars one company from both assessing and remediating the same job. Washington has no equivalent rule, so the separation is voluntary.

We test only. We never remediate, and we take no referral fees. In a landlord and tenant dispute, that is not a nice-to-have. A report from a company that stands to win the cleanup contract is worth very little to either party.

We are also straight about health. There is no diagnostic test that ties a specific mold to a specific symptom, and CDC has never established a causal link between Stachybotrys and serious illness. What is documented is allergic reaction, asthma triggering and upper respiratory irritation in sensitive people, plus genuine infection risk for the severely immunocompromised. Neither a landlord nor a tenant is served by exaggeration.

Frequently asked

A tenant says the unit has mold. Do I have to test? No. Washington requires you to maintain the unit and to give tenants the state's information on indoor mold hazards under RCW 59.18.060. It does not require testing. You test when you want an independent answer, when the dispute is escalating, or when you want documentation before you spend money on repairs.

I am the tenant. Can I hire you myself? Yes. Tenants hire us regularly. We will need access, and we will tell you upfront what a test can and cannot establish. What it can do is document conditions on a specific date with lab confirmation. What it cannot do is diagnose anyone's health or tell you what you are legally owed.

The growth is only in one corner behind the dresser. Is that a leak? Frequently not. Cold exterior wall surfaces plus high indoor humidity plus blocked air movement produce condensation growth in exactly that pattern. Psychrometric readings and thermal imaging separate a condensation problem from a leak, and they call for different fixes. One is ventilation and insulation. The other is plumbing or roofing.

Can you test a unit while the tenant is still living there? Yes, with proper notice. We ask that windows and doors stay closed for a few hours beforehand and that nobody vacuums that morning, so the air sample reflects normal conditions rather than disturbed dust.

We are buying a rental property near campus. Will the home inspector cover this? No. WAC 308-408C-030 excludes environmental hazards including mold from the Washington home inspection standards of practice, and WAC 308-408C-050 requires the pre-inspection contract to state that mold is not investigated unless separately agreed in writing. Your home inspector will flag it and refer it out. That referral is this.

How quickly can you get out here? Cheney is a short drive and we generally have appointments within a few days. During August turnover the calendar fills, so call ahead if you are lining up multiple units.

Book it
