"I’m writing this review as the property owner of a 1920’s apartment building in Santa Ana. We hired Atom Builders for a full roofing project on our flat roof, and I can confidently say they delivered outstanding service from start to finish. During our course of the project we were unexpectedly hit with rain and strong winds which caused the protective tarp to shift and resulted in a leak, as soon as Atom Builders was notified their team responded immediately! They sent out a full crew to assess and address the issue without any delays. What truly stood out was their commitment to making things right. Without hesitation, they offered and provided AirBnBs for the affected tenants to ensure minimal disruption and offered full reimbursement for any damaged belongings. Beyond that they even repaired pre-existing issues in the units going well above and beyond. John was very helpful and showed great customer service. if you’re looking for a reliable company, Atom Builders is the one!"

"I paid $62000 to have my roofs repaired - not cheap for a disabled person. Hopefully, thei dropping the ball is not because Im disabled. They removed but did not properly reattach my ATT line to detached garage. Also, there was a fluke rainstorm about 1-1/2 weeks ago and i heard a dripping sound in / near chimney. I complained and Brent Eikanas their contact promised to have supervisor here to check leak TODAY between 10-11 am and anchor the ATT connection like it was before they removed it. They no-showed AGAIN. I had to remind them of other items they needed to do to finish/using my payment as leverage - removing the old gutter all the way - they had only half-way removed it. I have photos and next winter will have to video and record leak in/near fireplace. I had to start documenting because phone call is useless. The workers left nails and some trash too and on Cinco de Mayo, their last day here, they did two structures in 4 hours,"
