Home Diagnosis

Grace and Corbett drive the #TinyLab a split-level ranch that hasn't been updated in decades. Ken is a retiree who's living alone now, and the house is just too big. His daughter thinks they could easily upgrade the performance to earn more when they sell- but they want hard facts, not just a hunch.

Grace and Corbett park the #TinyLab next to the oldest building in New York City, the Wyckoff House Museum. They test the two DIY tiny homes side by side, and explore what homeowners expected from home performance in 1650 compared to present day.

In an All-American suburb, Grace and Corbett test a typical house from the 80's, which has some very common (and some very uncommon) issues with performance.

Grace and Corbett analyze the performance of the most complex house they've ever tested. It has eight aquariums, two sunspaces, an indoor pool, two crawlspaces, two basements, two garages, and an industrial heating and cooling system. And it all performs according to design (because of the magic ingredient- his name is Matt).

Hosts and home performance experts, Grace and Corbett Lunsford, test and diagnose a recently rehabbed, big, beautiful house in Chicago, IL that now has unexpected comfort and moisture issues, leaving the homeowner not knowing whom to trust. The owner’s mother in-law room is never comfortable and moisture beads off the new kitchen windows. Corbett and Grace’s testing reveals a surprising answer and puts the concepts of “improved” HVAC on its head.

A New Jersey homeowner with a sensitive sniffer swears she can smell the air from the attic or the basement in every part of the house, but her family can’t back her up. Can Corbett and Grace use science to prove she’s not crazy?
