Review by in Boulder, CO
Tom Seibert & Gary Mancuso, principals. Very knowledgeable and exceptionally trustworthy. Felt like we could just give them keys to the house, leave for vacation, knowing that everything would be perfect when we returned. A very high trust level. The quality of the work was beyond our expectations and within budget and on schedule. Very easy to work with and we would hire them again in a second.

Review by in Boulder, CO
Energy Concepts was great to work with. Gary was accessible from the initial consultation through completion, and his team was professional, and reliable. The project started and ended on time. The remodeled bathroom looks great. And the expertise that was used in resolving unexpected (construction and electrical) issues along the way (and there was a lot of them!) was invaluable. Even though ours was a relatively small job, it was reassuring to know that the Energy Concepts team wanted to do it well. I would definitely call them again for our next project and recommend them highly to anyone else considering a remodel.

Review by in Louisville, CO
Project will start next week but Gary came out for the estimate, was very professional, provided estimate in a timely manner and we will be starting the project quickly. Right now the plans are for a quick completion since it is a straightforward job. Job is completed and better than I imagined. Work was done very neatly with minimal effect on rest of house. Finished product is top of the line using moderately prices finishes. The workmanship is superb. Would highly recommend.

They did an excellent job for us - great craftsmanship. I also liked how they offered suggestions for both landscaping and remodeling to come up with a great plan for our project within our budget. They were accessible for communication and always professional, and came with references.

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.
