A few reviews for this pro…



Eric found several problems regarding air leakage around doors, windows, flooring, missing insulation in home and crawl space and mold due to excessive moisture. He was very thorough, professional and friendly and provided pictures of all areas that need improvement.

Assessment for air leakage due to very cold temperature inside home

The inspection was worth the money. Being that my home is only 4 years old, insulation of the house was done fairly well. But did show some areas for improvement. The inspection did show that my duct work was in need of a lot of improvement. Eric was very professional and answered all of my concerns.

I was given a complete inspection of the attic, foundation and all relevant areas. Insulation levels, duct work and furnace were also inspected. A blower door test with an IR camera was used to check for air leakage. A pan test on all registers was used to check for duct leakage. My water furnace was inspected for heating equipment BTU delivery, operating equipment efficiency, duct temperature change, duct system efficiency. And was presented in a detailed HeatMaxx report. I also received a detailed home performance report. The report showed missing and ineffective insulation with thermal imaging pictures and gave recommendation to address each area. The report also showed areas of air leakage, duct leakage with recommendations to fix these areas. I was given recommended contractors to be able to fix each issue i our home.

Very pleased with the service.  Eric was extremely thorough and did a great job of explaining each test.  The final report exceeded expectations and identified many areas I would never have thought would have been a major source of heat loss.  I highly recommend Building Performance.

Fantastic.  Eric was professional, punctional and it was obvious his only goal was to give us an unbiased and accurate opinion on our home condition.  The report he provided was extensive, detailed, and easy for us to understand.  He went through it all so we were clear on what he recommended be done to correct the issues for the most affordable price.  He also provided contractors he would advise...

Eric provided a complete detailed report on our new home.  He did an energy audit, looking at safety, heating and cooling systems, duct leakage, incorrect insulation and recommendations for repair and better energy efficiency.

My fiance and I purchased our 90+ year-old Highlands home and knew it had some insulation issues but as first-time homeowners, we were a little overwhelmed by what to tackle first. Since we weren't eligible for the LGE home energy audit, I asked around and a friend had employed Eric (BPG) for an audit when she purchased her own leaky, old Highlands home a few years ago. I called Eric and he walked...

Thank you for your review [removed member name]! I'll make a point to change some of the terminology in our reports so they use more common language. Good advice, I appreciate it!
