He was very thorough and helpful with any questions that we had. I would recommend him to someone else to do an inspection. He was friendly and polite and even told the realtor to thank the home owner for moving her clothing out of the way to make it easier for him to get into the attic. My husband was with him more than I was but I know he was really satisfied with how thorough he was. He was on time and and introduced himself.

I was pleased with how quickly the inspection was scheduled and performed from when I first called Big Moose to order it, and how quickly the report was completed. The inspector, Mr. Van Fossen was friendly, professional, and told me what he was looking at throughout the home, and took the time to explain his findings to me. Derck commented on the positives, as well as any suggestions or concerns, and needs for repair. I appreciated all the photos throughout the report and the red arrows on some of the photos, pointing out examples of things noted in the report that require further attention. I appreciated suggestions of things to do to decrease heat loss throughout the home, as well as other suggestions that may need attention now or in the future. The report was clear & concise. I was very satisfied with the inspection and report, and will definitely recommend Big Moose and Derck Van Fossen to others. Thank you!

Thank you so much!!!!!!!!!!!!
- B.W., Traverse City MI, June 2012
I really can't say that Gary can improve on anything; other than I thought the low side pressure could have been measured in the A/C but it was too cold to operate. I was totally impressed by his courtesy, knowledge and professionalism. I'm much more versed in building methods and codes than the average person. This was very much worth the price for the level of detail. Thank you very much! crt
