I had an energy assessment done at my home in Winchester by Endless Energy, and the experience was outstanding — especially thanks to Brendan.

Brendan was extremely thorough, professional, and detail-oriented. He carefully inspected every area of the house and took the time to clearly explain the current energy efficiency conditions, potential issues, and recommended improvements.

I truly appreciated his patience in answering all of my questions. His explanations about insulation, air sealing, and energy savings options were very informative and helpful for planning future upgrades.

If you are considering insulation or any energy efficiency improvements, I highly recommend requesting Brendan from Endless Energy. The service was knowledgeable, honest, and genuinely customer-focused.
