"I initially hired Airtight Construction to replace my roof around August of 2020. Once airtight construction started working on the roof they informed me it was going to cost more. I was never given an estimate or a contract for the additional work. To date still no bill, though they ask for money continuously. While we are waiting for a roof inspection they started a kitchen remodel around sept. 2020. They removed my kitchen cabinets, replaced a few windows and did some electrical work. I began to worry about the work being done and called the city of Martinez for an inspection. They said some of the work Airtight Construction had done needed to be fixed. Things like Electrical Panel, the windows all needed to be removed because there was no sheeting. There are structural questions about how some of the beams they installed are going to be supported.. I now know no permits were pulled for the kitchen remodel,. though I asked for permits several times. I am now having to spend more money to hire new contractors to complete the job."

"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. "
