Why insulation matters in Santa Monica

In Santa Monica, the average January low is 8°C (46°F), colder than 4% 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.

Before you hire an insulation installer

  1. Ask whether they will air-seal before insulating, and what they will seal (attic hatch, pot lights, pipes, top plates).
  2. Ask for the R-value before and after for each area, and the material and depth they will install.
  3. Ask whether your rebate needs an energy assessment before and after the work, and who books it.
  4. Ask how they handle ventilation and any old insulation that could contain vermiculite (asbestos risk).
