Excellent company! Very professional, job was done in a timely fashion. Highly recommend and very happy with the work done, our entrance looks beautiful!


Devin's crew worked like a well oiled machine. They did the job in two days which truly amazed me. They did an excellent cleanup job after they were finished. I highly recommend Flawless Masonry to do anyone's job. Many thanks to Devin and his crew!


Asphalt driveway with block, great. Paver walkway and steps, great. Poured concrete cracked in 2 years. I should have listened to the salesman when he kept directing me to continue pavers. I now have to tear it out and redo it. Flawless it was not.

3.0 Sharon C. Centereach, NY

The workmanship was adequate. From day one, my diving board was never reinforced, the skimmers in my pool, sloppily done, one railing not put in wrong spot, and not even in properly and a lot of the sand is coming up in very obvious places. The "supervisor" apparently is not working for Flawless anymore and the owner, Devin has not made any effort to call me back. I will need to shell out more money and have another company repair their work.

Flawless Masonry did a great job. They showed up as promised and completed the work as plan. Devon was very professional in his approach.

they did a great job


Job was done earlier than expected. After I noticed that the fence wasn't put back exactly right, Devin came back the next morning to make sure it was fixed. No problem getting in touch with them and when they said they would be at my house they were. The patio looks amazing.

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.
