What Our Clients are Saying

Alex from Healthy Building Science was professional and efficient. We had our new home tested and implemented all his suggestions before we moved our family in. I highly recommend HBS if you are moving in a new home.

– Kim Koehler

Alex & Warren worked wonders coordinating our team for our home in San Francisco. During the design they helped define our healthy goals and made sure no detail was neglected. Our contractor has told us how much he appreciates Healthy Building Science’s help. We’re optimistic we’ll be getting a LEED certified building when it’s all done! Thank you for all your help!


Healthy in San Francisco

– Eric H.

So glad our water checked out. Your guy was super nice and smart and we’re just glad our water isn’t contaminated. Two thumbs up!

Thirsty in Oakland

– Jennifer O.

I cannot recommend Alex Stadtner and HBS highly enough!  Out of many people we have consulted in regards to environmental issues in the home, he is by far the most knowledgeable, affordable  and thorough.  We are so grateful to have found him and absolutely recommend him to anyone!


– Susan M. Menlo Park, CA

I was extremely impressed by Alex and Robert from HBS.  They responded to my email within a few hours and were able to come to our house for an EMF inspection the next day. Robert was extremely knowledgeable on both EMF and RF testing as well as safety and health concerns. I would highly recommend these guys to anyone!


– Ben S. San Francisco, CA

I highly recommend having your home checked for EMF. I myself am an EMF enthusiast and have devices to detect it, but these guys have a much broader range of devices to measure other frequencies.
The best part is, that they recommend electricians that can resolve the problems and even recommend types of materials that should be used to rewire the electricity.
They are a bit pricey, but compared to the fact that I could not find any information about the proper wiring on the internet, it was money well spent.

Santa Clara

– Vladimir P

My family recently moved into a rental home in Marin, and health being a high priority we called the folks at Healthy Building Science to give the house a good going over. Alex and his technician were on time and very thorough. I highly recommend being there for the whole inspection, my husband and I learned so much about EMF’s and electrical safety amongst many other things. The team found a problem with our range hood fan and quickly took care of the problem. I highly recommend them.
