5.0 Laron S. Georgiana, AL

Rekeyed 8 locks. Did a great job.

1.0 Steve G.

I hired him to fix crack in frame of door, He took the door off and took the glass out before re-installing, dropped the glass, and put two large scratches in the glass. He told me he would replace the glass and that has been since Aug 15th. I have called him multi times he told me he purchased the new glass but he needs to find where it is at. I called Pella and they told me they could not find the order anywhere in their systems. On 11-15 I called him and he told me he can not do anymore.

Response from Company:

Unlike companies that refuse to honor warranties, we honored the warranty and replaced the damaged window. Pella finally found order and replaced the damaged part. The customer, while inconvenienced (for which we apologized) received the replacement parts and it cost him nothing. We stand by our reputation and our hundreds of reviews. We are not perfect, but we are honest. Having been with HomeAdvisor almost 13 years and having racked up 400 reviews, we average 4.75/5 stars. Not because we are the cheapest. But because we are honest, straight shooters and we value ALL our customers.

We appreciated the quick assessment of our door repair. He ordered the right parts and fixed the door as soon as they arrived. I hope we don't have this problem again, but if we do, it's good to know who to call.

5.0 Sheryl J. Saint Peters, MO

I needed quick help on a door to my home that I was unable to lock and I was seen the same day, was very pleased and problem solved.

5.0 Bill F. Saint Louis, MO

I am beyond pleased with the service that I received from Master Key Systems America for my door issues today. Dan is professional, knowledgeable, and very comfortable to work with. He showed up on time as promised. My door ended up requiring non-standard parts, and he went out of his way to go get the correct items and finish the job the same day. He fixed it right the first time (everything works perfectly now), did so at a reasonable price, and was really conscientious about not damaging the floors or anything around him while he worked. He left everything clean when he was done. I highly recommend Master Key Systems!

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.
