    5.0 Sandra K. Portland, OR

    Mark was very helpful and knowledgeable. He was able to come on short notice and gave us some good recommendations.

    5.0 Christina M. Vancouver, WA

    Mark was quick to come assess the project for us. He was there for 15 minutes and knew exactly what we needed.

    5.0 Eddie D. Rhododendron, OR

    As owner/designer/builder, I hired Mark to validate the structural design of an atypical home on the Sandy River with challenging structural details. Mark also supported me during the building review process as part of his bid. The plans went through the county review first pass with no changes. After the start of construction, Mark advised on inspection issues and as built issues that came up allowing the project to move without delays. Even though he was on vacation, he responded to my requests during construction. The only improvement I would suggest is a bit more one on one collaboration early on to be on same page conceptually but with the pandemic and heavy client load in todays building environment, to be fare, that is a challenge for all engineers and my project was an oddity. I would use Mark again on a future house. He has integrity and that's number one.

    5.0 George M. Portland, OR

    Marc knows what he is doing and was available on short notice. Highly recommended.

    5.0 Meagan J. Oregon City, OR

    3.5 Joseph S. Wilsonville, OR

    i just hired Him. i have not received plans yet but we are coordinating now.

    5.0 Janet B. Milwaukie, OR

    I am delighted to offer this favorable review for Mark. When contacted, he promptly scheduled a site visit. Upon arrival, he thouroughly addressed each and every one of my concerns in a clear and straightforward manner and quickly followed up with a summary of his observations. With regard to his fee, one really cannot place a price on peace of mind. I personally found his fee to be more than fair given his knowledge, background and exceptional delivery of service. I would not hesitate to hire him again.

    5.0 Penny P. Vancouver, WA

    Mark was very prompt and professional and I do not hesitate to recommend him.

    5.0 Susan Q. Vancouver, WA

    Quick response, easy to work with. Cost of service is much higher than HomeAdvisor.com average estimate. Got what we need to satisfy the permit requirement.

    5.0 Barbara F. Vancouver, WA

    Very professional yet easy to talk to. He took time to explain to us what he was doing and what we should do.

    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.
