Founded on hard work, honesty and dependability by Glenn & Grant Farmer in 1951, G&G Insulation has remained a respected name in Idaho insulation for several decades.
Now owned and operated by Brandon and Whitney Gallegos, G&G continues to deliver high-quality products and services to the Greater Treasure Valley and Magic Valley regions. They strive to carry on the solid reputation of the G&G name through excellent workmanship on every single project.
The insulation contractor services residential and commercial accounts and installs thermal and acoustical insulation, as well as firestopping.
G&G Insulation started in 1951, and the new runners gained ownership 14 years ago, in 2010.
According to its principal, Brandon Gallegos, he became involved in the business as a summer job out of high school. Now, more than 32 years later, he is co-owner of the company.
The Idaho-based contractor is a member of ICAA, NICE, SRVBCA, MVBA and NAHB.
“In addition to commercial work, [we are involved with] custom homes,” Gallegos says. “I would say our niche services are in the custom home market, working with the customer/contractor to address their areas of concern and work towards their goals of the home, whether that’s energy efficiency, a custom wine cellar or sound concerns.”
Since Gallegos took over the business, has there been a lot of growth? Definitely, Gallegos says, adding that he became co-owner of the company at the downside of the Great Recession, in 2010.
Gallegos reports that the company is down a little in its market(s), but is also coming off a record-breaking year.
How has the current construction climate been in the region and for the company? “It’s been a strong market,” Gallegos says. “It’s changed since the Boise market was put on the map after coming out of COVID. Regional and national contractors have moved into the market that weren’t here before.”

Working It Out
What is the most interesting aspect of this job for Gallegos? Gallegos says he likes to take all the pieces, putting them together and making it all work out. On the flipside to that, what’s really challenging for him is material management.
Going into the fall retrofit market, the rest-of-the-year work outlook is looking at an upswing.
Gallegos says G&G Insulation’s long-term goals have remained consistent—to have consistent, profitable growth.
The company works with several different types of insulation, including fiberglass, mineral wool and rigid boards.

The Tamarack Resort in Donnelly, Idaho, is the country’s newest four-season resort. G&G Insulation installed thermal and acoustical insulation, and CCSPF was also used.
“[This helped the] thermal efficiency of the envelope, as well as performance in ‘snow country’ (i.e. ice damming and comfort) in the extreme winter temperatures,” Gallegos says, adding that Owens Corning Fiberglass and Natural Polymers Spray Foam were used.
“We are dedicated to quality and service. We stand by it, and everyone in the company works hard to stand out on every job we do.”
“I saw mistakes that happened over that last recession. Those will be life business lessons we carry with us and apply.”
