I recently hired Global 21 to install spray foam insulation in my garage, and I couldn’t be happier with the experience! From start to finish, they exceeded my expectations in every way. First off, the team was quick to respond to my request for a quote. Second, I had a quote on Friday and they worked me in first thing Monday morning. They were incredibly fast and efficient. They showed up a few minutes early, got straight to work, and completed the job without cutting any corners. It’s clear they know their craft well. Their pricing was also very competitive compared to other companies I researched. What stood out most was how well they cleaned up after the job. Once they were done, my garage was left spotless—no foam residue or debris anywhere. It’s rare to find contractors who take this level of care with cleanup. If you’re looking for a professional, reliable, and affordable company for spray foam insulation, I highly recommend Global 21. Great work!
