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 roofing job started off bad and continued to the finish. I wanted a professional with a few requirements. Be careful of original structure as it is prefabbed. The workers punched twelve holes in sheeting removing old roof material, requiring sheeting overlay. I requested that roofing nails not protrude through roof in patio area. They were protruding through the entire area. They left refuge sitting on the side of the driveway until I asked to have it removed. The one-week job turned into a two-month Odessey. The job was obviously a side job, piece-mealed together with little supervision little supervision. I am not confident the roof will not fail. prematurely fail. "

"Our experience is identical to what other reviewers shared. And yes, you should run from this company as fast as you can. Do not buy what Abraham shared that the payment must be made when the inspection is passed. Check the Business and Professions code yourself, the payment only needs to be made when the job is completed. It is very COMMON that the job is not even done or poorly performed even the inspection is passed. Here are the issues that multiple families including us run into with this company:: The project was delayed for over 9 months. No one manages the job. He often employs young men from his own Jewish community. They are enthusiastic but had no prior experience. The worse part is that they don't get paid. Two of them even set up a new construction business knowing Abraham will never pay them. Subcontractors can put your house on lien also. Many reviews you see on Yelp, Google, Angi are NOT genuine. Even the references are fake with hindsight, we were given 2 references. One reference shared the exact same accent as the PM. The other reference was initially happy with their work, but then reached out to us and shared a similar horror story with them like what we experienced. You will lose a lot of $$$ on materials as the subcontractors will somehow leave a thousand dollars worth of quartz at home. Maybe they want to compensate for the money Abraham owed them? Let me tell you, reordering materials is not fun."

FAQs for roof sealant application projects in Concord, CA

A roof coating system lasts between 10 and 20 years. With a premium coating and regular maintenance—like inspections and touch-ups—your roof will stay protected against weather damage and water intrusion. This enhances its durability and preserves its structural integrity throughout its lifespan. Make sure to keep in contact with a roof coating pro so that you don’t miss regulating resealing. 

You should recoat or reseal your roof every four to six years. Maintaining a consistent recoating schedule preserves the integrity of the protective seal and prevents moisture penetration and material degradation. High-quality, built-up roof systems require this interval, and if an EPDM roof begins to leak, replacing the coating becomes necessary to restore full protection.

A roof coating can seal small cracks and stop minor water infiltration, helping to prevent roof leaks. While the coating enhances the roof’s durability and prevents early signs of leakage, it does not replace the need for full-scale repairs when substantial structural damage exists. Professional evaluation and repair are required to resolve significant water intrusion and ensure your roof retains long-lasting protection.
