Each of the services provided by EnviroFocus is conducted uniquely, depending on the property type, size, the situation and the client. While some services may seem straight-forward, each will be approached in a customized manner by the inspector at the time of the appointment.

Following the appointment, your complete report will be issued with a consultant on-call to provide any explanations needed.

Do you have a mold problem?

1) Did you find mold? - Finding mold can be common around the shower and window sills with a lot of condensation. While these mold growths usually don't pose a serious concern on the surface, if they have grown deep down or started growing deep down, you may have a more serious issue.

Note about Black Mold: Many people have heard of black mold, but what most people aren't aware of is that black mold isn't the defining quality of a harmful or "toxic" mold. In fact, several types of mold known to cause harm to humans in elevated concentrations aren't even black in color. This is a common misconception. There are also a number of black colored mold that aren't considered to be harmful.

2) Do you suspect mold? - Is there a strong musty or mildew odor coming from an area of your house? Have you or another property occupant experienced unexplained allergies, respiratory illnesses or a unusual dermatological reaction inside the property? This could mean there is a hidden mold growth and the odor or health concerns is an indicator that mold spores have gone airborne from the growth.

3) Are you just being careful? - Are you buying or renting a different property? Are there no indications of mold growth, but you want to be sure there aren't hidden issues? Do you just want to be sure?

About Indoor Air Quality (IAQ)

One of the most important things every resident of San Francisco should think about is their health. Our health is our ability to function through everyday activities from work to hobbies and personal activities. It's our general-well being in life. While Californians are in general aware of their health and take steps to improve it, there is one important step people often miss.

While many individuals think about the quality of air outdoors, most don't think about the air quality indoors. Indoor Air Quality, or IAQ, is the measurement of the quality of the breathable air inside of a building.

Outdoor air quality in the San Francisco area is usually divided into two separately presented measurements: (1) Smog, chemical and gas levels in the air and (2) Pollen and mold levels (or allergen levels) in an area. The forecasts are often presented online or in a newspaper with air quality indexes (AQI) that show numbers and sometimes wording or images that symbolize the healthiness level of the outdoor air in a city or region. While the government or other organizations can forecast outdoor air quality for your neighborhood, there is no official report for the air quality in your home or business.

The myth that many often succumb to is that the inside of a seemingly clean and air conditioned building is a safe-haven from air pollutants. However, like outdoor air, indoor air can contain a number of contaminants that can pollute the air. Indoor contaminants are different because the air indoors is usually sealed off from the exterior. The pollutants that affect the indoor air typically come from building material or items within the building itself.

The truth for many is this: The air inside a building can be as bad, if not several times worse, than the outside air.

What are the most common contaminants that affect indoor air quality? - Mold and allergens. In terms of number of cases and reported health issues, mold and allergens showed to be the two most common causes of indoor air pollution and poor indoor air quality.

What is mold?

Mold, are fungi that can grow when dead or alive spores find organic material to feed off of with enough moisture and the right temperatures to support growth (a single mold spore is roughly ?? thick; a million spores could exist on a flat area the size of a postage stamp). The temperature allowing mold growth is quite large, from ?? to ?? degrees Fahrenheit. The amount of moisture and other environmental factors that support growth can vary by mold species, but the more standing water or humidity that mold has available, the larger and faster it will grow.

Mold can grow in open areas where there's sunlight or in dark crevices. It prefers locations where it won't be disturbed, but it can adapt to a variety of environmental conditions. Once a spore begins to reproduce, it forms a colony. Multiple colonies can form from there. From there, mold often spreads faster, going deeper into the material it's feeding off. Example: If an open area occupies one side of where mold is growing, say if it's growing on drywall, it will grow deeper into the wall and drywall rather than expand into the air-filled area because it's safer - free from moving air and varying environmental conditions. However, wherever mold grows, it will seek out moisture, whether from the air, condensation or pooling water.

Mold feeds off of organic matter, which many, if not most, buildings materials contain. This is how mold can grow inside homes and offices. Building materials, such as paint, adhesives, drywall, carpet and others contain or are completely made from organic matter. Organic matter includes plants, animals, people and other living things that, more specifically, contain cellulose matter.

How is mold a problem?

Mold is a problem for San Francisco residents and property owners for a few reasons. One, it's feeding off of your property's building material, weakening it, which can lead to structural integrity and building safety issues. Two, it's a sign of water damage that could mean a hidden leak from a roof, wall or pipe. Three, the most important, it can become a major health hazard to anyone, not just those with allergies or weak immune systems. Men, women, children, seniors and pets are all living, breathing organisms who can be adversely affected by contact with mold.

What types of buildings in San Francisco can be affected by mold?

Mold has a reputation that it’s only this green or black moss-like substance only found in dank, musty, humid environments or buildings. This isn't true. Mold can be found in any location where the environmental factors cater to mold growth. This can be a run-down home after foreclosure or a well-maintained newer home. Occupied, vacant, foreclosed or otherwise, no building is completely protected from mold growth.

How does mold affect people's health and cause health issues?

Mold can affect those who suffer from allergies or asthma, those with respiratory conditions (mild or severe), those with lower white blood cell counts, those with weaker immune systems (children, seniors or those with certain conditions, such as cancer, HIV-AIDS, sexually-transmitted diseases, or other health conditions), and healthy people, as well.

Seemingly healthy people can be affected by mold in the following ways:

  1. Excessive mold exposure to mold can trigger new allergies, both olfactory and dermatological;
  2. Exposure to toxigenic mold (or toxic mold) has been linked to lung infections, lung cancer, and the infection of open sores or wounds;
  3. Mold exposure has shown to trigger asthma in those who had asthma in their youth as well as those who've never had it (also known as Adult Onset Asthma);
  4. Exposure, mild or to elevated amounts in the air and on surfaces has been linked to other health conditions, which are still under medical study. Much about mold and health conditions are unknown.
    Whether or not you are a healthy and productive resident of San Francisco, you can be at risk of health complications from exposure to certain types of mold or elevated levels of mold.

How to prevent mold growth?

San Francisco can be a very wet and humid place to live. But sometimes steps can be taken to help prevent mold growth, despite this geographical fact. These include: Limiting humidity, promoting air exchange between the outside and inside of a home, fixing leaks and responding to water damage when they're first noticed and becoming well-acquainted with the various points of your property.

Quote often, however, no matter how much a home is maintained and steps are taken to ensure an environment free of excess moisture, hidden growths may occur.

How do I know if I have a mold problem?

If you aren’t sure if a mold problem exists at your property, whether or not you or someone close to you are currently suffering from allergies, asthma, allergic reaction or a respiratory condition, the only sure way to know is by getting a professional mold inspection with mold testing. Much like how official measurements are taken to determine the air quality outside, a mold inspection of your property will determine the quality of the air inside. Through a combination of onsite equipment measurements, a visual inspection by an experienced and certified IAQ professional and air and surface sampling (testing), you can get an accurate understanding of the types and levels of mold within your property.

EnviroFocus provides complete Indoor Air Quality (IAQ) investigations for San Francisco homeowners, business owners and tenants. Following these evaluations, a complete inspection report that includes third-party laboratory analysis findings from any air or surface samples taken during the inspection is provided to the client, along with recommendations on how to eliminate any found issues.

When it comes down to it, this report will show you if the breathable air inside your property contains potentially harmful types or levels of mold.
