In business in California for more than a decade, Superior Insulation has seen a good response from its recent building improvements and adding a sign to its Buchanan Street location.

Eric Call bought the business, which specializes in spray-foam insulation, in 2017 from his partner Josh Feilbach, who started the business in 2007. Today, the business has three full-time employees and serves a 50 mile radius of California.

The business has evolved as new techniques and materials come into the market. The business started out with the traditional blow machine attic insulation, then added the spray foam in 2015.

Call said he makes it a priority to stay informed about changes to environmental and code regulations, as well as the ever-changing world of building science.

Except for building contractors, most of Call's clients will be one-time customers. His approach is not just to sell a product and service, but to examine the whole-house situation to see what insulation method will be serve that customer's need, he said.

If done right, the spray-foam insulation can double a home's efficiency and provide a homeowner with a return on his investment within five years.

No two houses are the same. And maximum energy efficiency is easier to accomplish in new construction. That doesn't mean existing homes couldn't benefit from improved insulation.

"People are losing money out of their attics," Call said. If someone lives in an old home with a high energy bill, he said "you can do stuff about that."

Call's priority is what is best for the homeowner, he said. He takes into account the type of home and what other infrastructure is in place. Then, he weighs cost versus return and energy use versus green materials.

"Every house is different," he said. "If you have a question about how to make your house more energy efficient, I want to be the guy to answer it.

"I take a sense of pride in educating people."
