Stop Guessing. Proof Is Possible.

Grace and Corbett Lunsford moved the Building Performance Workshop to Atlanta, Georgia to help homeowners get the advice, scientific testing, and home improvement consulting they need. As an independent consultant and verifier of home performance through testing the envelope and HVAC systems, all things in a home can be proven. Proof Is Possible- ask for it.

NOW IN ATLANTA! Want to prioritize improvements in a home, or prove that a new or improved home will perform better? I'm Corbett Lunsford, and I help my clients understand home performance so it can be easily used to prove home improvement and home construction actually WORKS.

NOTHING CAN HIDE IN A HOME'S CONSTRUCTION NOWADAYS. The testing equipment and techniques are so advanced that we can help you solve any problem you have, in any type of home, new or old, anywhere in the country.

Home improvements and new home construction are testable and measurable. Never assume plans are rock solid or work was done perfectly- PROVE IT.

I've helped hundreds of clients get control of their homes, and trained hundreds of building pros to earn more money doing better work for their own happier clients. I love sharing the secrets of tuning a home's performance- get in touch, and you'll actually get ahold of me personally.

Since I specialize in building forensics, you can count on accurate results. Since I remember what it's like to have tons of questions, you can count on clear explanations. And since I don't sell other products, you can count on unbiased advice.
