What a insulation costs in Los Angeles
Price depends on which areas you insulate (attic, walls, basement) and how much air sealing is needed. Ask each company for a price per area and the R-value you end up with, so quotes are easy to compare.
That could cut your cost by up to $374 if you qualify. Most rebates have rules (income, your current heating, a registered contractor, approval before work starts).
Rebates: our verified program data, checked monthly. Always confirm the exact amount for your home.
Talk to a home energy auditor first. Some utility programs want an audit before any work starts. See the home energy auditors we list.

Why insulation matters in Los Angeles
In Los Angeles, the average January low is 8°C (46°F), colder than 5% of the 123 cities we track. Winters here are mild, so comfort and summer heat matter as much as heating bills. Air sealing and attic insulation still help most, and they also keep upstairs rooms cooler in summer.
Most rebate programs pay only after an energy assessment, and some need one before the work too. Book it first.
