How to choose an insulation contractor in Kentucky
Audit first, with a blower-door test
A home energy audit (look for BPI or RESNET credentials) uses a blower door and often an infrared camera to find where Kentucky air is actually leaking and which assemblies are thin. The report gives you a prioritized scope, which is what you hand to insulation contractors so every quote prices the same job. Many Kentucky utilities subsidize audits; ask yours before paying full price.
Air seal before you insulate
Insulation slows heat flow; it does not stop air leaks, and air leakage through the attic floor, top plates, recessed lights, and the rim joist is usually the bigger loss. A good quote lists the air sealing it includes (and the material: foam, caulk, rigid covers over can lights), keeps attic ventilation and bath-fan ducts clear, and checks that combustion appliances still draft safely after the house is tightened.
Compare quotes on R-value, material, and coverage
Each quote should state the material (blown cellulose or fiberglass, batts, open- or closed-cell spray foam), the R-value being added and the final target for your DOE climate zone, the square footage, the depth markers used to verify coverage, and whether old insulation is removed. Ask for proof of liability insurance, any general contractor license your state requires, and a written warranty against settling.

Your utility sets the rate your insulation savings come off, and it is also who an installer files interconnection or service paperwork with, so name it when you ask for quotes.

Insulation itself is not electrical work, but junction boxes, recessed-light covers, and attic fans in the work area are: Electrical contractors in Kentucky are licensed by the Kentucky Department of Housing, Buildings and Construction, Electrical Division.
