4.0 Falls Church, VA

Friendly, fast, and they delivered what I requested on my time schedule.

4.0 Tim P. Arlington, VA

They were great. Friendly, fair price, on time.

5.0 Priscilla G. Alexandria, VA

Excellent. Estimator and workmen who came to home were thorough and did a great job. We were happy with this pro and would recomment them. My computer will not let me enter anything in that block.

5.0 Gail R. Reston, VA

Very responsive! Had insulation enhanced in my attic and an attic fan replaced. For each job, they were knowledgable, on time, and cost conscious. During my 2nd job, they had a sales person leave so the owner took over managing my job directly and made sure everything was done timely and correctly. I was impressed with his service commitment.

4.0 Candide B. Reston, VA

They were on time and very professional! Unfortunately one of the boards in my attic wasn't nailed down and one of them put his foot through my ceiling. He was very apologetic and came out the next day and repaired it. Immediately, we noticed a difference in the temperature.

5.0 Fairfax, VA

They were prompt, and gave me an estimate on the spot. The estimator took the time to explain what and how he putt together the estimate. On installation day they arrived promptly on-time and performed the scheduled work. i am very pleased with the process, speed of response and quality of the workmanship.

5.0 Ed E. Manassas, VA

The installer was very good,and walked me through as to what he was going to do,and did a fine job.The only hitch was he acted like he didnt read the contract as to I paid for and what was expected of him to do,so I had to remind him of it.But overall it was a great job done and he cleaned up after himself.So I'd recomend Advantech again .

4.0 Herman F. Alexandria, VA

Provided great service. Would call upon them again to do other projects.

4.0 Falls Church, VA

5.0 Alexandria, VA

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.
