Company principles & culture


Knight Environmental Consulting LLC, part of the Knight Group global was founded in 1995.  We are the leading international provider of technical mold inspections, air testing, mold testing and water quality testing. In the USA, Knight is the leading supporting mold inspection and testing company for realtors in three states: Arizona, California and Nevada. We serve the high end luxury real estate mold inspection market also where we know how to deal with high net worth clients and their expectations. We help our valued clients with their indoor air quality and mold testing and inspection across the USA.

Our philosophy is simple: We help home owners, realtors, tenants, parents and students with mold and environmental issues in their homes. We deliver air quality consultancy services to the highest professional standard of ethics for every property inspection.

Our down to earth scientists are the very best in the industry. Every inspector has a minimum of 17 -33 years of hands on environmental experience. Many of our team players have advanced Masters and PhD degrees.

As part of the Knight Group we have completed 1.37 million property inspections in several countries. You will find we are competitively priced for all budgets.

We hire local inspectors helping the local economy.

Internationally our affiliates serve real estate clients and the pharmaceutical and biotech sectors in other countries. Ensuring our clients production facilities have excellent air quality. In 2003 we began selling equipment to help filter air of particulates and contaminants. Becoming a major supplier to those concerned about mold, particulate contaminants and mold allergens.

By ethics we also mean we only inspect your property for mold and do not offer to fix it too.

How qualified are your inspectors?

All of our staff are certified scientists with multiple degrees, Masters and/or PhDs. We are way ahead of all of our competitors in terms of training and experience. We will never send you a technician or a hygienist. Our well informed clients choose Knight because we do not send inspectors with no science experience. Our teams can actually discuss environmental issues with you in detail. Our water testing staff are highly experienced chemists and biologists also.

A true consultant is a scientist with advanced degrees, so while other firms claim they are consultants, it is completely misleading to you, as the consumer as they are providing inaccurate information.

People spend a lot of time in the home or office. Let us make it healthy for you. Give a KNIGHT scientist a call and we will help you by inspecting and/or testing your property for mold, poor air and water quality.

Humanitarian Work

At Knight Environmental Consulting it is part of our humanitarian responsibility to donate profits from property inspections and environmental testing to the Asthma Foundation USA, Cystic Fibrosis Foundation USA and Chlorosolar.com. The money is spent on quality research and care of sick children and healthy air education. We donate air quality equipment for improved air quality to low income families also. We love helping communities and giving back. There is a good chance you have found us by a referral too because past clients have had a great experience.
