Does Your Basement Look Like This?

How do Molds get in the Indoor Environment and how do they Grow?

Mold spores occur in the indoor and outdoor environments. Mold spores may enter your house from the outside through open doorways, windows, and heating, ventilation, and air conditioning systems with outdoor air intakes. Spores in the air outside also attach themselves to people and animals, making clothing, shoes, bags, and pets convenient vehicles for carrying mold indoors.

When mold spores drop on places where there is excessive moisture, such as where leakage may have occurred in roofs, pipes, walls, plant pots, or where there has been flooding, they will grow. Many building materials provide suitable nutrients that encourage mold to grow. Wet cellulose materials, including paper and paper products, cardboard, ceiling tiles, wood, and wood products, are particularly conducive for the growth of some molds. Other materials such as dust, paints, wallpaper, insulation materials, drywall, carpet, fabric, and upholstery, commonly support mold growth.

ZWS Environmental Services, Inc. performs Indoor Air Quality (IAQ) evaluations and water damage assessments in commercial and residential buildings throughout the Midwest. Our services are typically used by individuals dealing with IAQ issues (mold growth, bacterial contamination, chemical contamination, etc.), and/or by individuals dealing with water damaged buildings.


ZWS is a third party consulting service. We do not perform structural drying or environmental remediation (clean-up), nor are we directly affiliated with such a company. Being strictly a third party consultant eliminates any ‘conflicts of interest’ while conducting our assessments. There are several companies that perform both assessments and remediation, which is a conflict of interest because these companies directly profit by telling you that your problem requires remediation. This is not the case with ZWS.


After ZWS performs an assessment, a specifically designed ‘scope-of-work’ is prepared for all identified problem areas. That scope-of-work is then used by remediation/restoration companies to rectify these areas of concern. If a problem is not found, ZWS will prepare a ‘Clearance Notification’ stating the property has been assessed. Clearance Notifications provide documentation of the property’s acceptable condition, which can help our clients sell their property and/or eliminate potential liability issues.


What separates ZWS from other third party consultants is our experience, training, and the technology we use. ZWS is a long standing corporate member of the Indoor Air Quality Association (IAQA), and the Better Business Bureau (BBB) of Wisconsin.




ZWS’s founding members have successfully performed thousands of IAQ and water damage assessments. ZWS is a ‘preferred vender’ for hospitals, nursing homes, general contractors, property management companies, real estate companies, insurance companies, and engineers throughout the Midwest.


We have the experience, capability, and manpower to handle any size job.
