The Fifth Fuel of Virginia, LLC

The Fifth Fuel is a family owned and operated business. With over 30 years of experience in the industry, we’re not new to energy conservation and building science. As leaders in energy efficiency, we invest in educating our staff. The Fifth Fuel team receives ongoing training to stay on top of building science innovations. We are a Class A contractor operating in VA, DC, and MD. We are large enough to weatherize and insulate a multifamily subdivision yet small enough to take care of a cold floor over a small addition on the back of the house.

Josh was great with the estimate and the installation crew were clean and professional. Our upper level is now noticeably cooler on hot days. Well worth it.

They were on time with both calling and showing up to the job. They were polite and neat, placing plastic coverings over all areas they came in contact with and totally cleaned up after competing the job.

They did a before and after energy saver and it turned out to be a 20% difference. I cannot wait to see the difference in my billing cycles. The pros were absolutely amazing, I felt very confident that they were not trying to give me something I did not need. I had someone before them do an assessment and they lied to me about what I needed and over a thousand dollars more than the fifth fuel. I want to give a special thanks to Josh,Edgar and Ervin. They all were fantastic.

Arrival was right on time! i needed insulation in 2 attics. They ( Enrique, Jonathan and Walter) protected my carpet, floor and furniture. They worked steadily from 8 am until 4 pm. They were polite and did an excellent job. Luis came to inspect the work done and came the next morning to insulate/seal the door in a bedroom going to one attic and did not charge any additional fee. I feel warmer already! Hope that extra money spent on high electric and gas bills will warm my wallet and bank account! I highly recommend this company!

I had multiple estimates and Fifth Fuel was the most professional and reasonable. Josh came to my house, took pictures of my attic and explained the different choices of insulating the attic. He provided an estimate in writing the same evening. The installers arrived on time, sent me photos of the before and after. They left the house clean with no debris. The result is a huge improvement in the temperature between the upstairs and down. I couldn’t be happier with them! Outstanding!! Thank you!

Seal of Approval

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.

NOTE: Member service professional information confirmed as described above may change or expire over time; while HomeAdvisor attempts to maintain accurate and up-to-date information, and confirms changes when notified, we cannot guarantee that profile and screening information is accurate.
