A total waste of money. After they forced me to pay in advanced for the plans, the city and contractors would not accept their garbage plans. Asked them to revised and was told "that's what the plans call for" Had to hire and pay a real engineering firm. Stay away from these people, they have no clue as to what they are doing.

We met with Peter explained the problem and our proposed solution. Peter provided an alternate that made sense and will save money in the cost of the project.

Site evaluation: the engineer was thorough and professional. Site evaluation report: hand written, somewhat incomplete and difficult to decipher. Construction design: their nearest competitor would have charged us $600 for both the site eval and construction design plan. We went with Erdelyi because their fee was lower for the site eval, and we didn't know we would need the full design. Big mistake. The cost of the design was huge.

I hired them to evaluate our property in regard to remodeling our attic. They checked the foundation and retaining walls and advised on what we would need to add more weight to the structure. We were able to get the information we needed to proceed to the next step.

They have been very efficient in dealing with my rather simple project of removing structural walls in an old home. They are pleasant and friendly. I will certainly use them again.

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.
