    First impressions are everything. 100% confident after our first 2 minute call.

    3.5 Miles S. Saint Louis, MO

    Dealing with a structural concern, I was looking for insight and options to address the issue. I was pleased with the information received. The cost was explained prior to appointment and even though I knew the cost, I feel the evaluation based on the time spent on site to be rather expensive.

    5.0 Jesse F. St Louis, MO

    Dr G was helpful and quick to respond. The engineers that came out were thorough and professional, they were great.

    5.0 Saundra W. Saint Louis, MO

    Quick and efficient. These guys were amazing with their overall interactions with me. They explained everything in detail. I will definitely use these guys again in the near future on other projects I have.


    Thorough and informative.


    I was playing around on HomeAdvisor looking for a structural engineer around 8PM and within a couple of minutes Dr. G called my phone. He was very professional and at the end of the conversation he texted me his information to contact his Administrator in the morning. I called Heather and had an appointment to meet with Dr G at he house that same day at 2PM. I arrived on time and he was already there looking at the outside of the foundation. He was able to answer all my questions and reassure me that the house would be a good purchase, but also recommended work that needed to be done most likely in the future. We had our letters from him written that same day and we were done with everything in less that hour. If you are buying a house and are concerned about the foundation, I highly recommend Dr. G. He works for the buyer and makes sure you know everything and every problem that might arise in the future with your new home purchase.

    Dr. G worked through a challenging job and got everything completed in the short deadline that was given.

    5.0 Alexandre T. Saint Louis, MO

    I received very thorough advice and detailed plans from Dr G at DOTEC for replacing sagging support beams in my basement and bring the house up to code. Very grateful to him.

    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.
