Would highly recommend! Mold is no joke and can be scary. A lot of companies use scare tactics but not AEL! From booking with Stacy to Jim showing up for the appointment— it was a smooth and very educational experience. Can’t say enough great things about this company. Great advice, timely results (they have a real biologist on site!!) and very easy to understand.
