About Us

about ultimate home performance Ultimate Home Performance is a licensed general contractor. Bachi Brunato, our building scientist and lead contractor has been certified by the Building Performance Institute (BPI) as a Building Analyst Professional and Envelope Professional. We operate as a full service Building Performance contractor utilizing a Whole House approach to increase comfort, reduce energy costs, and lessen your carbon footprint.

As a building performance contractor we look at how all the systems in the home interact. We are not invested in any single trade or approach. Our goal is to deliver effective, performance based solutions that will improve the comfort, health and energy efficiency of your home.

Using state of the art equipment and a whole house approach we diagnose and repair everything from drafty rooms to poorly performing heating systems. After any upgrade we re-test the house and all of our work to make sure that it is performing as we intended. This way you can be assured that the solutions we recommend and install will truly address your needs.

Bachi has been in the trades 35 years, learning construction from an early age from his father who was a structural engineer and general contractor. He has honed his skills over the years in carpentry, plumbing, electrical, and most of the other trades. Bachi studied architectural engineering and construction management at Cal Poly, San Luis Obispo. He has spent time working as a creative landscape construction builder, enjoying the opportunity of integrating his clients' lives into the nature around them.
