When You Need A Mold Inspection:

Any place in your home or business with excess moisture, such as standing water or condensation, can foster the growth of mold. If left unchecked, the growth and spread of mold inside a building may lead to health problems and building damage. According to the Centers for Disease Control and Prevention, symptoms can range anywhere from a stuffy nose, eye irritation, wheezing, or skin irritation, to more rare but severe allergic reactions such as fever, shortness of breath and even mold infections in the lungs.

Attic Mold Testing & Inspection

Attic mold is almost always the result of high humidity in the attic space. This high humidity causes condensation on the cold portions of the roofing materials (plywood or OSB) and results in mold growth on these surfaces. Attics should be designed with proper ventilation in mind. This would usually include low vents (soffit vents, bird-blocks, etc.) and high vents (roof vents, ridge cap vents etc.). Current code in Washington State requires 1 square foot of ventilation per 300 square feet of attic footprint. This is a general rule, but the type, location, and air-flow through the individual vents should be evaluated by a qualified inspector to determine exactly what has caused the deficiency that led to the attic mold growth. A neutral unbiased attic mold inspection will give you the information you need to find out exactly what the next step should be.

"This company is great and goes above and beyond for their clients. I had researched other companies and heard about St. John Environmental and gave it a try. To say this company exceeded my expectations is an understatement. The owner goes over every last detail and leaves nothing untouched. If it’s not absolutely %150 up to standard he is not satisfied whatsoever. I love a company that can leave a job knowing there was nothing unfinished and did an awesome job. Highly recommended. If I could give more stars I would..”
