"Would not recommend Atom Builders under any circumstances. They completely botched a roofing job at our building in Santa Ana. Left the roof uncovered right before a storm, which flooded units and caused ceilings to cave in. Mold started growing quickly, and instead of handling it the right way, they charged ahead without permits or testing for lead and asbestos. This is an old building?it obviously had both. We were told to just ?air things out? and not worry, even as walls were soaked and materials were clearly compromised. Then they brought in some guy who wasn?t even licensed to do mold inspection. Just used an app on his phone and said everything was fine. When the city showed up, they made Atom stop work on the spot for doing all of this without any permits. Turns out lead was confirmed later through actual testing. Meanwhile, people had to leave their homes and pay out of pocket just to be somewhere safe. When tenants returned, their places were still a mess. Paint over outl"

"This crew , led by Marcelo Cândido, was amazing. Everyone was polite, patient with us when we had to discuss the options, and kept the area clean at all times. Even though there was a small language barrier we felt heard and we were able to communicate through an interpreter, one of the assistants - communication was easy. They finished in time and kept their word about clean up and keeping the roof covered when a bit of rain fell during the job. I highly recommend this company, especially Marcelo and his crew. "
