Glenn was the 3rd contractor we went to replace the door in our mudroom, the first one was bad at getting back to me and the second one fell off the face of the earth. Glenn was very professional and he did a great job.

Project: New Windows
I have used Glenn of Phase One Construction for many home projects within the past year and I highly recommend him to anyone who is looking to have quality work done at a fair price. I will be using him again in the Fall for several more home projects.

My project was to remove the old deck and install a new deck with stairs and railings. Glenn and his company did great craftsmanship and analysis of necessary work. He is very efficient and timely. I will definitely be using him for future home repairs and projects!!!--Regina

Glenn is knowledgeable,professional and a really nice guy. He responded immediately and came when he said he would. His price was more than fair. Orlando, who works for him, is thorough and hard-working. He stood on that roof as if he were the ground. When they were finished cleaning the moss off our roof it looked like new. They power-washed part of our house that needed it while cleaning up the residue from the job. They did great work. We will recommend Glenn and hire him again for other jobs.

Glenn is extremely easy to work with and very accommodating. His work is very meticulous which is key for me. Response time was pretty much immediate after sending an e-mail or placing a phone call. He is extremely trustworthy. I will definately use Phase One Construction for future work. I can't say enough nice things about him. I would recommend Glenn 100%.

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.
