At Airtight Construction, Inc., we provide a wide range of services. We specialize in roofing and we service both residential and commercial clients. Headquartered in Concord, our fully equipped and professional staff can meet any construction, renovation, or retrofit need; and can serve as a single point of contact for even the most complex or time constrained project. We are committed to a responsive delivery of flawless craftsmanship combined with the industry's best customer service. We bring a proven expertise and time tested techniques to every job site. While most companies rely on sub contractors, we have in house crews to handle any job.
"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."

"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. "
