May 30 - Seattle, Washington
Mold Inspection

Just moved in to an apartment in Seattle a little over a week ago; there is a smell of mold throughout most of the place. I know that I am allergic to mold, and I started feeling sicker than 'normal summer allergies' within a few hours of moving in. The property manager swears there is no mold in the apartment and that the smell is due to stagnant air. How much would it cost to get a mold/mildew inspection/consultation for a 2 bedroom apartment?

What laws or regulations cover mold inspection and removal issues in Seattle?

The following is a summary of Washington state and City of Seattle landlord/tenant regulations (last updated 8/15/2011).

  • The landlord must provide tenants with information provided or approved by the Department of Health about the health hazards of indoor mold, including how to control mold growth to minimize health risks, when a new tenant moves in. The landlord may give written information individually to each tenant, or may post it in a visible, public location at the dwelling unit property. The information can be obtained 
  • A tenant must be current in the payment of rent including all utilities to which the tenant has agreed in the rental agreement to pay before exercising any statutory remedies, such as repair options.
  • Required Notice [RCW 59.18.070] When something in the rental unit needs to be repaired, the first step is for the tenant to give written notice of the problem tothe landlord or person who collects the rent. The notice must include the address and apartment number of the rental; the name of the owner, if known;and a description of the problem. After giving notice, the tenant must wait the required time for the landlord to begin making repairs. Those required waiting times are: 24 hours for no hot or cold water, heat or electricity, or for a condition which is imminently hazardous to life; 72 hours for repair of refrigerator, range and oven, or a major plumbing fixture supplied by landlord; 10 days for all other repairs.
  • Tenant’s Options [RCW 59.18.090] If repairs are not started within the required time and if the tenant is paid up in rent and utilities, the following options can be used: 1) Tenant can give written notice to the landlord and move out immediately. Tenants are entitled to a pro-rated refund of their rent, as well as the deposits they would normally get back.  2) Litigation or arbitration can be used to work out the dispute.  3) The tenant can hire someone to make the repairs. In many cases the tenant can have the work done and then deduct the cost from the rent. [RCW 59.18.100] (This procedure cannot be used to force a landlord to provide adequate garbage cans.)
  • Finding -- 2005 c 465: "The legislature finds that residents of the state face preventable exposures to mold in their homes, apartments, and schools. Exposure to mold, and the toxins they produce, have been found to have adverse health effects, including loss of memory and impairment of the ability to think coherently and function in a job, and may cause fatigue, nausea, and headaches.

    As steps can be taken by landlords and tenants to minimize exposure to indoor mold, and as the reduction of exposure to mold in buildings could reduce the rising number of mold-related claims submitted to insurance companies and increase the availability of coverage, the legislature supports providing tenants and landlords with information designed to minimize the public's exposure to mold." [2005 c 465 § 1.]

Below is a list of frequently asked questions our mold experts often receive.

What type of services are typically offered by a mold inspection and mold testing company in Seattle?

A professional inspector in Seattle will typically offer the following services: mold Inspection, black mold inspection, mold detection, toxic mold testing, moisture intrusion detection (Leak Detection), pre-purchase inspection for real estate transactions, allergen screening for dust mites, pollen, pet dander, indoor air quality testing, (IAQ) Seattle, Washington.

Where is Mold Typically Found in Seattle area homes?

Mold growth can occur anywhere the conditions are correct, however certain areas are much more common. These include the crawlspace, attic, bathroom and near plumbing fixtures. Crawlspace mold damage often occurs during new construction or in warm environments using air conditioning. Attic mold damage is common in cooler climates and occurs when warm air from within the home condenses on the cold surface of the attic sheathing. Bathroom mold is very common, though often is more of an aesthetic problem than a health issue. Plumbing fixtures, however, can be a source of major mold problems, and if left unattended, often wood rot as well. Carpet mold is less common, however carpeting can often harbor old deactivated mold spores for many months after the source of the mold growth has been addressed.

Seattle environmental services are a key part in keeping your home safe. It is essential to find a qualified, certified toxic mold testing service to check your living conditions. Environix can help you find this qualified professional.

What is involved in the Mold Inspection & Mold Testing process?

A thorough mold inspection typically involves two main components, a visual inspection and sampling. The visual inspection focuses on identifying the extent of the visible mold growth and the conditions conducive to mold growth. This portion of the inspection often entails moisture meter testing, thermal imagine, humidity testing, CO2 and CO testing. Depending upon the scope of the inspection the process is either limited to a specific portion of the building or encompasses the entire property. Visual inspection and air sampling will identify problem areas that may be adversely affecting your Indoor Air Quality. Learn more about a typical inspection process.

Symptoms of Mold Exposure in Seattle

The primary health effect of exposure to mold is through an allergic response. Asthma, allergies, and sinus infections can all result from exposure to mold spores. It is important to remember that mold spores are ubiquitous and occur naturally in the outside air. Much like pollen and other allergens, these reactions are possible in sensitive individuals even at levels found in the outside air. The goal of indoor air quality testing, therefore, is to determine if the mold spore counts in your home are elevated beyond the levels normally encountered in the outside air.

Respiratory infections are also possible, though typically only occur in susceptible individuals with compromised immune systems. These people are often confined to hospital clean rooms. The toxic effects of mold growth are far less understood. Scientists are unclear whether an individual can receive sufficient exposure to mold growing indoors to cause the toxic effects.
