    Bottom-line, I agree with the others who rated them negative. The subcontractors he hired & didn't pay put a lien on our home. We had already PAID H3 for their services but he didn't pay them. MESS, big mess!!!

    From the ground breaking to the dedication, I found H3Construction to be an effective, professional organization which delivered on its promises. they were responsive and accessible to our concerns, requests....I would recommend H3 for any commercial or public construction project....

    home addition in FREMONT

    Excellent service and professional!! we are extremely satisfied with their crew work ethics and attention to problems and details. Our home addition is not possible for Thanksgiving holidays without Hans Ha (owner)'s going extra mile to complete it within two months. They passed 95% of inspections the first time and immediately resolved problems as soon as within that day. We highly recommended H3 Onesource Builder to anybody who wish to have their home projects getting done on-schedule and no-hassle.

    Do NOT use H3 One Source Builder (Bay Area )

    11/01/2008

    The owner Hahns Ha does not return calls and you cannot leave a voice message because his mailbox is full. We are located in San Jose, California. **** H3 started our remodel in April 2008; the owner Hahns is NEVER there when we have an appointment with the city inspectors. He sends one of his workers whose communications skills are not through. We have failed more inspections than passed. **** H3 does not keep with their work schedule timeline - Do NOT use H3 One Source Builder - quality or workmanship is poor, customer service is horrendous ***** **** Our rating is negative stars but that was not available. -* -* -* -* -*
