"You certainly get what you pay for! While CSI wasn't the cheapest on our list of home inspection and radon testing quotes, the cost was more than reasonable for the level of service that we received. Ron, our home inspector, was fantastic! He arrived early, and I don't think he could have been more thorough than he was! He was very friendly and personable, and was more than willing to answer our questions during the inspection. He went through the entire home with a fine toothed comb! He pointed out defects that he found, and explained things in detail. He also highlighted the positive things he found. Used a drone to inspect the roof and chimney, and thermal imaging to check for hidden moisture. I feel like we have an excellent idea of the condition of the property we are buying, which has done a lot in making us feel more comfortable! The report we receiced within 24 hours was professional and clearly written with appropriate photos attached. Will certainly recommend to others, and will use them for any future home inspection needs we have!"

"The energy audit surfaced some significant issues. That's what we wanted. Shelter Alternatives presented a bid for the job, which seemed high. We are checking with other contractors to complete the work."
