Why a Licensed General Contractor Matters
“I started Josh Brooks Construction and Renovation Inc. in 2014 with one goal: do the work right, pull the permits, and stand behind it. In Colorado, anyone can call themselves a contractor — but a licensed general contractor is accountable. My license number is CON-24-0152. You can verify it. That’s the kind of contractor you want on your project.”
