Jason and Danielle

When Jason and Danielle were contemplating starting First Summit Home Inspections, they reached out to friends to ask about their home inspection experiences.

“He told us; ‘Your gonna die,’” Anna said to Danielle.

Anna and her husband were new parents and were home shopping. Unfortunately, the inspector scared them and they ended up passing on a home that they really liked.

What was the eminent cause of death? A miswired outlet in the home. Granted, a miswired outlet should absolutely be reported. However, in almost every case, they can be fixed by an experienced electrician.

Jason then knew that this was the right place to put his experience and understanding of how a home is constructed to work for homebuyers.


When it comes to Home Inspections, experience matters.

Jason’s career in the construction industry started in 1994. He worked as a Superintendent and Project Manager of large residential housing projects and high-end custom home projects. In 1999 he earned his General Contractors license and later his Real Estate Brokers license in the State of California. He has supervised the construction of over 450 homes and sold real estate as an Associate Broker at Re/Max.

Curiosity and a desire to learn other aspects of the construction industry led him to become a Sales Manager for Owens Corning in their Roofing & Asphalt Division, an Architectural Sales Manager for Interstate Brick and most recently a Business & Product Development Manager for a prominent Commercial Roofing Manufacturer.

  • Former Licensed General Contractor in CA (Lic #761418)
  • Former Real Estate Broker in CA (Lic #01463546)
  • Supervised construction of over 450 homes
  • Extensive construction materials sales experience

His understanding of a home from product manufacturing to construction and sales gives Jason a unique ability to describe a home and its components in a simple and easy to understand way. After over 20 years of working with Architects, Engineers, Contractors and Agents, he decided it was time to put all of this experience, and his love for homes and people, to the perfect use, helping homebuyers feel confident and well-informed when buying.

Jason/First Summit Home Inspections is AMAZING!! Very professional and he goes the extra mile. We used him to inspect a house in a standard purchase contract. The report was very thorough and extremely detailed. Not only that, but in his online system you could actually see the suggested steps to remedy anything that was noticed. Can’t speak highly enough of them. If you’re looking for an inspector, use First Summit Home Inspections!
I would highly recommend Jason Lange and First Summit Home Inspections. To give a brief overview, I found Jason and his work thorough, comprehensive, detailed, and friendly. During my inspection process for purchasing a house I First Summit Home Inspections. While I wasn't able to personally attend the inspection due to work, Jason worked with my realtor so he could be there; I really appreciated that he was flexible enough to do this with a third party. Some additional services I utilized besides the standard home inspection was a sewer line scope, radon testing, and thermal imaging. He was very thorough and went above and beyond; he had an extremely thorough report for me that he not only emailed me, but also physically gave to my realtor to pass to me. This report had everything I could've wanted and more, things I wouldn't have thought to check or even consider were on there. The report was comprehensive and even included multiple pictures to help illustrate and highlight what he was describing. The report website was easy to use and had every single item inspected ranked on a scale of severity. With any problem noted, he included ways to mitigate or correct them. He got into every space possible such as everywhere on the roof and in the separated attics, tested every single fixture and outlet, and tested every single water line comprehensively. The best part was the phone call he coordinated with my family member who was purchasing it with me; during this call, he personally went over the report, addressing every single item in it. He was very patient and answered any questions we had and educated us on issues that are unique to Colorado. I was very grateful for his time.

Jason performed a radon test at my house. Jason was very informative, answered my questions, and provided excellent service. He practiced COVID safety protocols, always wearing a mask. He even put on shoe booties before coming into the house, very nice. The report was detailed and included several other documents to provide more information about radon.

Jason performed radon testing for us. We were very satisfied with the quality of his work. Very professional, followed all COVID protocols, explained what he was going to do, and was on time for initial test and followup test. His reports were very helpful about the dangers of radon and what our options were. We would use him again and would recommend his firm to anyone.

Jason Lange was highly recommended to us recently. Can't say enough about how satisfied my wife and I are about the expert service we received. Jason is polite and very knowledgeable. He practiced Covid safety by wearing a mask at all times while in our home. He,also, puts on shoe covers which protected our carpet. In getting to know Jason we discovered he has extensive experience in home building. He checked our furnace room and our crawl space while in our home at no extra charge even though he was only here to do a Radon test. We heartily recommend First Summit Home Inspections without reservation. Thanks Jason, Tim and Debra Specht
