Review by in Aurora, CO
Larry re keyed two patio doors to match the existing entrance doors. One was a Pella and the other a Anderson. He was prompt, professional and reasonably priced. I will keep his information and definitely hire again

He was an hour early and finished the job in under 45 minutes. He did a great job! I kept his card because I've already referred him to another person.

Review by in Centennial, CO
We recently rekeyed a new home that we bought. We also lost the mailbox key to our cluster mailbox in our new home. I thought it was a complicated process involving usps to receive replacement keys however our problem was solved very easily since Larry removed the old lock and replaced it with a new one. Cost was also very fair and reasonable.

This was the easiest work I have had done on the house. I called at 8, they were there at 11, and finished just before noon. Very professional and considerate. I would hire them again and will recommend to friends and family

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.
