5.0 Declan Lavoie Google Review

Very diligent staff to guarantee that the pre-agreed-upon pricing is met, and they provide what they promised! Even in the bitterly cold weather, everything went off without a hitch.😍😍

Response from Company:

Thanks Declan

5.0 Ushmendra S. San Bruno, CA

Awesome!! There was a mistake in their quote and they had overlooked an item and I expressed concern about unforeseen or extra costs after the work had begun. I do understand it happens sometimes so they were willing to split the cost or complete the work with no additional charge on another matter. The owner of the company stayed engaged till the work was done to my satisfaction. They left the work site and all traffic areas thoroughly cleaned. If I had to do it again I’d hire them all over. Very professional and pays attention to the customer’s needs and concerns. Very satisfied and highly recommended.

We were lucky to find this insulation company attic efficiency to do a job in our home and we are extremely satisfied with the result. From the first contact, the company was professional and attentive to our needs. After a detailed evaluation of our home, they provided us with a clear and detailed quote for the installation of insulation. The installation was carried out by a highly skilled team, who worked efficiently and respectfully in our home. From protecting work areas to cleaning up after the installation, everything was handled with care and professionalism. The end result is that our home feels much more comfortable and energy-efficient. We have noticed a significant reduction in our energy costs and an improvement in indoor air quality since the insulation installation. In addition, outside noise has been significantly reduced. In summary, we are very pleased with the work done by this insulation company. From start to finish, the process was easy and professional. I would recommend this company to anyone looking to improve their home's energy efficiency and comfort

I needed to have my Cold Cellar insulated, so I called up Attic Efficiency. Asaf came out to the house for a free at-home estimate. He was very helpful and knowledgeable. When the crew came out to do the job, everything was completed as quoted and everything was left tidy and neat. I highly recommend Attic Efficiency! Great Service!

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.
  3. Verification of State Business Filings
    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.
  4. Criminal Records Search
    HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
  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.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
  7. Legal Search for Civil Judgments
    We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them.
  8. Liens Search
    We use 3rd party data sources to check the principal/owner of the business for liens placed against them.
  9. Identity Verification (SSN)
    HomeAdvisor verifies the social security number(s) of the owner/principal for identity check purposes. This check applies primarily to smaller business entities.
  10. Identity Verification (Reverse Phone Lookup)
    We conduct a reverse business phone lookup to identify records matching the phone number information provided by the business.
