Very high quality level of construction…. Very organized, excellent follow-up. A pleasure to work with. Very happy with my rehab.
Our experience with 126 Builders was a dream! Hiring a contractor for large job, a home addition, is intimidating. 126 was one of a few contractors we met with initially. We liked that their bid was not only detailed and fair, but transparent too. Transparency was key for me. It reflects honesty. That integrity continued through the entire project. Their team hustled! Showed up on time to work everyday and worked everyday until the job was done. Ricky, William and Ruben are the dream team! The communication from the office side was continous, friendly and always informative. Angee and April are on top of everything, helping us to ensure we were prepared for each step. I will admit, I was not the easiest customer to work with! I changed my mind on a few things, questioned things, etc. They always responded with a "no problem" attitude. Customer service is top notch! We highly recommend them for your next build/remodel⭐⭐⭐⭐
Great company
I would not reccomend.
I’m glad that I chose 126 Builders Inc to build my ADU. The employees are great, always on time, respectful and stick to their work schedule. In at 7:30 and out at 4:00. The company delivered what it promised. Finish the project on time and our ADu looks great. i highly recommend 126 Builders Inc for any construction projects you might have.
I recently had a plumbing issue at my home and reached out to 126 Builders Inc — and I’m so glad I did. From the moment I contacted them, their team was responsive, professional, and incredibly helpful. They quickly scheduled a visit, arrived on time, and diagnosed the problem right away. What really impressed me was how clearly they explained the issue and the steps needed to fix it — no upselling, no pressure, just honest, straightforward service. The work was done efficiently and with great attention to detail. They resolved the plumbing issue faster than I expected, and everything has been working perfectly since. On top of that, they left the work area clean and tidy, which I really appreciated. If you’re dealing with a plumbing problem and want it fixed right the first time, I highly recommend 126 Builders Inc. They’re reliable, knowledgeable, and genuinely care about their customers.
