Business Overview

How We Got Started

I chose to work in this industry because When I was 7 years old, my mother came into the Basement to check on me. She found me by the fuse box with the panel cover off and I was playing electrician..

We started in this industry in 1995.

We describe our business as Well established

My words of wisdom.

It takes an extra 15 minutes to do it the professional way as opposed to just getting it done!!

Review by in Wadsworth, IL
We were told by several contractors that the bathroom exhaust fans were causing a mold problem in the bathrooms. 4B Systems came out and did a thorough inspection and informed us the ceiling fans were very good and working properly. The looked at the duct work and said the ducts were designed properly, however, the wrong material was used. He said the ceiling fans were not the problem and provided a quote to replace the duct work. He was honest and professional and we would recommend them in the future.

Review by in Vernon Hills, IL
Rob was really great working with us and the city to get our required permit after many many many submissions/requests for the plan of where we wanted to place the new 200 amp panel. Eventually a location was agreed upon and Rob and his assistant got the work turned around and got the work done quickly and went the extra mile to make sure that all the things we requested were done - even trying to anticipate what the next phase of our project, HVAC work, would need and making sure that they would also have what they needed where they needed it. We will definitely be hiring them again for more work in the future!

Robert and his assistant showed up on time and completed the work efficiently, professionally, and thoroughly. He was great to work with and took the time to answer my questions and discuss the details of the project. I'm very happy with the outcome of the project, and the price was very reasonable. Highly recommended.

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.
