What to know about Attic insulation
Insulating an attic is the highest-value envelope job in most American houses, and the Department of Energy's Building America guidance says so directly: the attic is the first place a contractor should insulate, and air sealing plus added insulation in an attic can do more than any other insulation project to increase comfort and cut energy bills. It is also the job most often done badly, because the part that matters is the preparation rather than the depth of the blanket.

Prices depend on the details of your project. We only publish price ranges when they’re backed by real LokalMatch quote data or reliable sources. Until then, here’s what usually changes the price:

- Type of insulation
- Removal of old insulation
- Air sealing work
- Access to the space
- Ventilation changes
How to choose insulation contractors in Vacaville
- Choose a contractor who talks about air sealing and ventilation, not only adding more insulation.
- Ask them to check the attic or walls for moisture, mould, old wiring or insulation that may contain asbestos before starting.
- Get a written quote that states the type of insulation, the areas covered and the target insulation level.
- For spray foam, ask about their training, curing time and when it's safe to be back in the home.
- Consider an energy audit before and after the work to see where heat is being lost.
Questions to ask insulation contractors before you hire
- What type of insulation do you recommend for this area, and why?
- Will you seal air leaks before insulating?
- How will you keep the attic properly ventilated?
- What will you do if you find old insulation that may contain asbestos, mould or old wiring?
- For spray foam, how long do we need to stay out of the house?
- Does this work need a permit or an inspection?
