"The guys were really neat. They set up a tunnel from the attic to the back door. There really wasn't much to clean up after. They vacuumed out the old insullation and laid in new. It's hard to say if they did a good job in the attic, because I don’t know what its supposed to look like. They were in the attic almost about 7 hours. The only issue was that they said the senior discount on their Angie's list page must be old so they didn't honor it."

FAQs for attic insulation installation projects in Walnut, CA
The best attic insulation depends on where you live, the project stage, and your budget. New builds often benefit from structural insulated panels for top-tier efficiency, while homes in very warm regions can see big cooling savings with reflective insulation. Blown-in, loose-fill, and spray foam all excel at filling odd spaces in finished attics. Talk with a certified local pro to match the material to your climate, space, and wallet.
You’ll only need a licensed electrician if the project calls for moving existing wiring or adding new fixtures. For straightforward insulation jobs, your insulation installer can work around current cables. That said, never start insulating until a pro has checked any questionable wiring. If you suspect damaged or outdated circuits, book an electrician first to keep the project—and your home—safe and code-compliant.
Without air sealing, even the best insulation can underperform. Gaps let heated or cooled air leak out, forcing your HVAC system to work harder and driving up energy bills. Sealing those cracks before adding insulation locks in conditioned air, keeps moisture at bay, and helps the new material hit its full R-value. Ask your insulation pro to tackle sealing first so you enjoy consistent comfort and lower monthly costs.
Among readily available options, structural insulated panels and rigid foam boards top the charts with R-values that can reach 8.0. They’re ideal for new construction or very cold climates where maximum thermal resistance matters most. If you live in a milder zone, blown-in or loose-fill insulation may deliver plenty of performance at a lower price. Weigh the upfront cost against energy savings—and lean on a local pro’s guidance—to pick the smartest fit.
