Common Questions
How do I know if I need more insulation?+
High energy bills, uneven room temperatures, drafts, or visibly low insulation in the attic are all signs. We'll measure during a free assessment.
How long does installation take?+
Most attics are completed in a single day depending on size and access.
Is the estimate really free?+
Yes — we assess your attic and provide a written quote at no cost or obligation.
Do I need to be home?+
Yes, an adult homeowner or authorized person must be present during the service.
What insulation R-value do California homes need?+
Most California attics call for roughly R-30 to R-38. We measure your existing depth and recommend the right level for your climate zone.
Should old insulation be removed first?+
Only if it is wet, moldy, rodent-damaged, or heavily compacted. Otherwise we can often add new insulation on top after air sealing.
Are rebates available?+
Many California utilities offer insulation and weatherization rebates. We will point you to the programs that may apply to your address.
