Serrano Fire Protection Systems

We had a very large project that required new sprinklers on all four floors of our home. The project included installing in both new construction and upgrade of existing parts of the house. The work was done in a professional manner and we got through all of the permitting with San Francisco with no surprises. I would definitely use them again and recommend them for others.

Mario and his son completed our entire fire sprinkler system for a whole home renovation in Marin. They did the entire project including; The engineering calculations, the fire sprinkler system designs, all the permitting, the entire installation, and final trim. I'm very happy with their work and my overall experience. Mario is very responsive, a hard worker, and gives you a complete and straight forward price from the start. I would use them again on future projects.

We've worked with Mario on many different projects and can't recommend him too highly. High quality work, fair pricing, respectful attitude and attention to the details. Our current project had to do with extending sprinkler heads to accommodate a new surface covering the ceiling. We were pretty surprised that we could get no one else to come out at a time when Mario was busy with larger projects. But in seeing this, he agreed to help us. His work was flawless in a circumstance that might have been damaging and costly. We're very happy with the work!

Mario was great to work with on our 4 unit building. He got all the permits, drawings, was on time and on budget. Easy to communicate and job ran smoothly.

Mario and his son have not only done a great job at our building in Corte Madera but they helped explain things along the way and made a complicated process a little less stressful.

Over the last 10 years, Serrano Fire Protection Services has designed and installed the fire sprinkler systems for the 8 houses that I have built in Southern Marin. His designs are effective and practical and he works well with the fire inspectors. He is on time and on budget and has never had to come back for repairs. I highly recommend Serrano and his crew.

Mario does great, professional work. Would recommend.

Mario is a quality sub-contractor who is well priced and does a good job

Best fire sprinkler contractor by far in the Bay Area!
