I hired Jenny to test my indoor air quality because my daughter has bad allergies. Jenny immediately responded to my quote request and even offered a Yelp discount . She arrived on time for our appointment and was very knowledgeable and professional. She contacted me over the phone with the results and provided the report within 24 hours giving me peace of mind about my indoor air quality. The report also has suggestions to improve the air quality. I would not hesitate to refer Wycoff Environmental to anyone requiring a similar service. Thank you Jenny.
