We had rodent damage in our crawlspace. Thermalux came in, cleaned everything out, sealed all entry points, and re insulated. Our home feels completely different now. Highly recommend!

Insulation FAQ for Los Angeles Homeowners

Here are the questions we hear most about home insulation costs, LADWP rebates, and how the installation process works. If you don't see your question below, just call us at (323) 515-0317 and we'll be happy to help.

Ask a Question
How much does insulation save on energy bills in Los Angeles?

Most Los Angeles homeowners we work with save anywhere from 20% to 50% on their energy bills after an insulation upgrade. How much you save depends on your home's size, the current condition of your insulation, and what type you go with (blown in, batt, or spray foam). On average, that works out to about $600 to $1,200 per year in savings. Want to know your number? We offer a free energy assessment. Schedule yours today.

What is the LADWP insulation rebate and how do I qualify?

The LADWP (Los Angeles Department of Water and Power) gives cash rebates of up to $1,500 when you upgrade your attic insulation. To qualify, you need to be an LADWP residential customer with attic insulation currently rated below R 19. That covers a lot of older LA homes. We handle 100% of the paperwork, make sure everything meets the program requirements, and help you get your rebate as fast as possible. Contact us for a free rebate eligibility check.

How long does home insulation installation take?

Most residential insulation jobs are done in one day. A standard attic insulation project usually takes about 4 to 6 hours. Something bigger like crawlspace encapsulation or drill and fill wall insulation might take 1 to 2 days. We always give you an exact timeline during your free in home estimate so there are no surprises. Book your free assessment now.

How much does insulation cost in Los Angeles?

It depends on the type, the area size, and the material. For an average Los Angeles home, attic insulation usually runs between $1,500 and $3,500. Crawlspace encapsulation is typically $2,000 to $5,000. Now here's the good news: with LADWP rebates (up to $1,500 back) and flexible financing, most homeowners find the upgrade pays for itself within 2 to 3 years just from the energy savings alone. Get your free, no obligation estimate.

Is Thermalux Insulation licensed and insured in California?

Absolutely. Thermalux Insulation is fully licensed, bonded, and insured in the state of California. Every one of our insulation technicians is certified and goes through regular training on the latest installation methods and safety standards. We carry full general liability insurance and workers' compensation coverage, so you've got complete peace of mind from start to finish.

What areas in Southern California does Thermalux serve?

We cover a big chunk of Southern California. That includes Los Angeles County, Orange County, Ventura County, San Bernardino County, and Riverside County. Pasadena, Long Beach, Glendale, Anaheim, you name it. If you're not sure whether we serve your area, just give us a call at (323) 515-0317 and we'll let you know right away.
