5.0 Pawan H. Fremont, CA

Good experience. Reasonable price and quick service. Took the time to answer questions and explain everything to be done.

1.0 Sheila M. Palo Alto, CA

I think the truthfulness of their contract is very questionable, he would verbally imply that customers would get rebate but the contract does not show that the customer gets the rebate but the E3 company does.

Response from Company:

I'm sorry that there was some confusion over the contract. It is true that there are rebates available for attic insulation. We generally give those rebates as an instant discount to customers and then have the rebate sent to us. That way the customer isn't paying for the work and having to wait a few months for the rebate themselves. We are happy to do it that way if you would prefer.

5.0 Gabreil L.

Excellent work, efficient , and done in a timely manner!

4.0 Gregory G. Los Angeles, CA

All went well

5.0 Jack D. North Hollywood, CA

They made things so easy for me and took care of paperwork etc. This is how it should be done.

5.0 Hal M. Northridge, CA

They do not charge you per sq foot that is not utilized in the attic.

5.0 Seth W. North Hills, CA

Great service and price. Company handles the rebates for LADWP and Socalgas and the out-of-pocket cost for blown-in attic insulation is minimal (25 cents / sf).

5.0 Lona D. Chatsworth, CA

Friendly, fast, clean

5.0 Judy M. Porter Ranch, CA

Everyone working for this company explained the program, inspected the insulation, completed the work in two hours and all this done in 2 working days. They handled all the paperwork as well. Personally they are the nicest and most competent people we have worked with. They did everything for us, even cleaned up as well. They all worked together like family and we felt like a part of such a lovely group for the time they were here.

5.0 B M. West Hills, CA

They were very friendly and knowledgeable. Work and cleanup was satisfactory. They completed all the paperwork for me to send to the LADWP to process the rebate. Even provided the stamped envelope. Only time and my next few bills will indicate whether adding insulation to my attic will really reduce my electrical costs.

What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.

    For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.

  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
