He has not done any work and does not respond either.

5.0 Sharon B. Houston, TX

It was a very good experience. Yohan was confident, his skills was excellent. Low key mild manner character. Gave recommendations and was able to deliver in a timely fashion. Notified you if he was running a little late, every consideration was given. Very pleased with results.

Yohan Yi is a true professional His crew worked efficiently and maintained a neat worksite in spite of having to deal with several inches of rain during the project

5.0 Karen S. Houston, TX

Y-Square Design did a great job on the wrought iron fence I needed. It was a small project but they also installed some new sod to replace where my dog had worn down. Yohan was very responsive and professional and his crew was very thorough. I had a couple other bids and his was overall the best choice, in terms of quality, ease of communication, and reasonable rate.

5.0 Helen C. Houston, TX

Yohan was very efficient and professional in coming to quote and setting up the work. The crew were outstanding, top-quality work, polite, very careful of the neighbours, efficient, cleaned up very well after themselves. Highly recommend Y-square.

5.0 Ned G. Houston, TX

We could not be more pleased with the fence installed by Y-Square Design! Yohan Yi's communication with us from start to finish was excellent--very professional and caring about what we wanted to have done. His crew is top-notch, professional and courteous, and the workmanship is excellent! We strongly recommend Y-Square, and will work with them in the future.

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.
