Sham and his crew built an awesome deck and remodeled a basement room. He was neat, timely and responsive to phone calls and emails. Very easy to work with. He has all my future business.

Review by in Pinecrest, CA
Sham redid the kitchen but also sheetrock, flooring, and trim in upstairs sleeping loft, plus removing old linoleum and refinishing original wood floors in living room downstairs, redoing stairway and handrail. He transformed our small knotty pine cabin. Was really sensitive about the look and quality of materials, gave us great advice, was a perfectionist on the kitchen tile and trim. Well informed, on budget/on time, brought in other experts to do little details. We couldn't be happier.

They were professional, punctual, clean and courteous. Our names should read Dave & Nancy H. I don't know why $amp shows as part of our name, Can you please remove it before you post our names? Thank you.

Review by in Jamestown, CA
The project consisted of: a complete renovation of kitchen, tile floors throughout 90% of the home, interior painting of 90% of home,and new kitchen window and more. Sham and Mike came up with a great new design for the kitchen cabinets and window. The whole project turned out perfect. My home had nice views before, but now you walk in and there is definitely a "wow" factor. If you contact him, ask him to show you photos of it. I am definitely satisfied..

Way more professional and concerned about quality than other contractors in the area. No worries about the craftsmanship portion or the business portion

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.

NOTE: Member service professional information confirmed as described above may change or expire over time; while HomeAdvisor attempts to maintain accurate and up-to-date information, and confirms changes when notified, we cannot guarantee that profile and screening information is accurate. Therefore, we recommend that before working with a service professional you verify that information presented is still current and/or acceptable to you.
