    Very prompt, very polite and courteous, great working ethics, clean work. My area around the pool looks great now. While doing the repair work Mark found large sink hall under the cement hat caused damage and repaired it. Many many thanks! Would hire him again when needed.

    I had my front step replaced because it was cracked in half. Mark replaced my step promptly and at a great price! He was courteous and professional. I would definitely recommend his company!!!

    Not sure how this job could have gone any better! Mark came out and gave me an estimate the morning I expressed interest on Home Advisor.com. He gave me a fair price and did the job the very next day. The work was great and his customer service was excellent. I'd use him again without question.

    My back yard had no patio and I had numerous estimates done that were extremely high. I almost gave up on the idea of having a patio until I called Mark Weldon. Mark helped me get the patio I wanted for a price I was able to afford. Mark was fair, knows what he's doing and got the job done fast. I definitely recommend him and will be calling him again for any other masonry/concrete jobs I need done.

    Fast, prompt, high-quality of workmanship at a fair price. Actually comes out when he says he will, either on time or early. Goes well beyond what is expected. Other service providers should learn from him on how to really service their clients!

    Mark called me back immediately. He is extremely friendly and outgoing. Once we confirmed the date he showed up early and ready to work. The brick retaining wall that he replaced on my property is so well crafted and looks beautiful. Mark is a true craftsman and hard worker. I will definitely be hiring him again in the future.

    A callback was placed within the hour. Service was completed on the first dry day after signing contract (3 days). Excellent Service; Courteous, and left the job site clean.

    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.
