The City of Las Cruces handles permits for home projects. Whether a given wall insulation job needs one is the city's call, so before work starts I check with the office that covers your address. If yours needs a permit, we apply for it, set up the inspections and keep you posted on where it stands.
New Mexico's residential energy code puts Las Cruces in climate zone 3B, so whoever insulates your walls should know what that code expects of houses here. The state's Construction Industries Division licenses insulation work, and its public license search lets you confirm a contractor holds a valid license before you hire anyone.
We're based in Las Cruces and do the same work in the cities around it, including Chaparral and Anthony. Wall calls here usually come from west-facing rooms that soak up afternoon sun and stay warm into the night, and from houses where nobody knows what, if anything, is inside the walls.
