Questions people ask about insulation contractors in Los Angeles

How many licensed insulation contractors are in Los Angeles?

57 insulation contractors hold an active Contractors State License Board (CSLB) licence with a mailing address in Los Angeles, checked on 4 November 2026. 24 of them have been licensed for 10 years or more.

Does a insulation contractor need a licence in California?

Yes, when the whole job, labour and materials, costs $1,000 or more or needs a permit. Below that, California's minor-work exemption (B&P Code 7048) applies, but only if they work alone. Look for an active C-2 licence.

How do I check a insulation contractor's licence in Los Angeles?

Ask for the licence number and look it up on the CSLB website, or search this page. Every insulation contractor listed here was matched to an active licence on the CSLB register.

Which insulation contractors rank highest in Los Angeles?

By our published formula (years licensed, complaint record, bond and insurance, and Google reviews), the top three are Everguard Home Insulation Inc (98), Mike's Building Corp (90), So-cal Insulation Inc (86). Paying or claiming a listing never changes the order.

How much do insulation contractors charge in Los Angeles?

Insulation contractors in the Los Angeles-Long Beach-Anaheim metro earn a median $23.30 an hour (BLS, May 2025); contractors typically bill about twice the wage to cover insurance, overhead and profit.

Do I need a lead-safe certified insulation contractor in Los Angeles?

If your home was built before 1978 and the work disturbs paint, yes: the law requires a firm certified lead-safe by the US Environmental Protection Agency. 69% of homes here were built before 1980 (US Census, ACS 2024 1-year), and 3 of the 57 licensed insulation contractors listed are certified.
