Brenda S. says, "Moises helped me with my vinyl flooring project, and I couldn’t be more satisfied with the results. From the beginning, he was professional, punctual, and very easy to work with. He took the time to make sure everything was measured and installed correctly, and his attention to detail really shows in the final outcome. The floors came out clean, smooth, and perfectly aligned. He worked efficiently but never rushed, making sure every part of the job was done right. He also kept the work area neat and respected my home throughout the process, which I really appreciated. What stood out the most was his craftsmanship and pride in his work. It’s not easy to find someone who cares this much about quality. If you’re looking for someone reliable and skilled for flooring or home projects, I highly recommend Moises. I would definitely work with him again in the future."See more

Kelly M. says, "Working with AGR Homes Inc. on the complete remodel of my Manhattan Beach home was, without exaggeration, one of the smoothest construction experiences I've had, and I don't say that lightly. A full-house remodel is the kind of project where small oversights compound quickly into expensive problems, and AGR simply didn't let that happen. From the first walkthrough to final punch list, their team operated with a level of discipline and attention to detail that's genuinely rare in residential construction. Timelines were communicated clearly and held. Change orders were documented properly. Subcontractors showed up when they were supposed to, and the site was managed like a job site should be organized, protected, and professional. What stood out most was the quality of the finished work. Every trade, framing, finish carpentry, tile, paint, and fixtures were executed to a standard that held up under close inspection. The home doesn't just look renovated; it feels built. That's a distinction that only becomes obvious once you've lived in it for a while. I'd recommend AGR Homes Inc. without hesitation to anyone undertaking a serious remodel or new construction project in the South Bay. They price their work for responsibility, and they deliver accordingly."See more
