Mary S. says, "Excellent! This is feedback for 2 jobs done the same day. #1 Bathroom cold faucet drip turned out to be big job replacing piping and manifold behind the wall. Miguel and Carlos did a VERY neat job, were professional, patient and timely. #2 Installation of whole-house water filter. Instead of a water softener, the Halo brand uses filter media and ion control. Big job burying the 5-ft filtration cylinder in the ground and redoing piping and appurtenances into the house. Again, Miguel and Carlos did an excellent job, were very knowledgeable and great to work with. Technician George started me out on understanding what I needed and options and worked with me on pricing. All GOOD!"See more

Nathaniel G. says, "I recently had a plumbing issue at my home and reached out to Sonny’s A1 plumbing—and I have to say, I was beyond impressed. From the moment I called, the professionalism and responsiveness were top-tier. He picked up right away, asked all the right questions, and made time to come out the same day. Once he arrived, he was punctual, respectful of my home, and walked me through everything he was doing. What really stood out was his knowledge and confidence—he diagnosed the problem quickly, explained it clearly in simple terms, and had it fixed efficiently without trying to upsell or cut corners. Not only did he solve the issue, but he also double-checked the rest of my system just to make sure everything else was in good shape. It’s rare these days to find someone who actually cares about doing the job right and takes pride in their work. If you’re looking for an honest, reliable, and skilled plumber who treats your home like his own, I highly recommend giving Sonny a call. I’ll definitely be using him for any plumbing issues in the future—and I’ll be recommending him to friends and family without hesitation."See more

He showed up, listened to my concerns and quickly communicated what he was comfortable doing and what he wasn’t. I would highly recommend him for your plumbing needs, whether it’s installing a trench drain in your back yard or fixing a leaking faucet. Very good experience!"See more
