John was a godsend! He did everything in a timely and professional manner. He kept me informed throughout the repairs, and finished on time. I appreciated his work ethic and found him to be an honest, hard working man. I felt extremely lucky that John answered my request on HomeAdvisor.

Jon went out of his way to stay in touch with us, and took care of our house. Jon is knowledgeable, hard working and professional. Jon is not just a contractor; but a teacher as well as he educates you on what he is doing in your house.

They removed old hot/cold water pipe insulation that was in poor shape, and installed high quality rubber pipe insulation. Removed old support uprights that where of poor quality, and not installed correctly. Installed new high quality uprights, and attached them to the support beams. Jon and his team at Square 1 Venture Group far exceeded my expectations. From first contact till the end of the project their communication and workmanship was first rate. They gave daily updates with the progression of the work which also included pictures. They were always reliable arriving on time, and put in a full days work. Very honest to deal with showing receipts for the materials that where purchased, and also came in under the bid price. When the jobs where completed they left the worksite in excellent condition. They do high quality work for a reasonable price and do it right the first time. I would definitely hire them again.

Jon was all around great. Very professional, prompt and reliable. He communicates very well and keeps in contact about everything that is going on including changes. His job came in under the original bid due to less work needing to be done than originally expected. I would hire him again, hands down.

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. Therefore, we recommend that before working with a service professional you verify that information presented is still current and/or acceptable to you.
