DO NOT HIRE -- READ THIS FIRST I had an extremely negative experience with Cerenzia Fence Company, owned by Mark Serenzia. What started as a simple fence installation turned into one of the most unprofessional interactions I've ever had with a contractor. Communication was poor from the beginning. Messages were ignored, timelines were unclear, and when I attempted to follow up, the owner became hostile. During a phone call, he was aggressive and used profanity toward me, which was completely unacceptable. After that, I received multiple harassing and inappropriate text messages. At no point did this interaction feel professional or respectful. What was most alarming was his behavior in person. He repeatedly got into others' personal space, raised his voice, and acted in a confrontational manner that felt volatile and unsafe. Several interactions appeared close to becoming physical altercations. This was not a tense moment -- it was a pattern of aggressive conduct that made those present uncomfortable. Additionally, there were serious concerns regarding his condition while on the job. He arrived appearing disoriented and unfocused, with very red, bloodshot eyes, and seemed disengaged from the task at hand. Whether due to fatigue or other factors, his overall presentation raised major safety concerns about judgment, awareness, and the ability to safely perform physical labor on a residential property. There were also unresolved legal red flags. I was unable to obtain clear verification of proper licensing or workers' insurance. This creates significant liability risks for homeowners if injuries or property damage occur. This was not merely poor customer service -- it was an unsettling and unsafe experience. Between the aggressive temperament, lack of professionalism, questionable on-site behavior, and unresolved legal concerns, this company presents a serious risk. Beyond the communication issues, there were serious red flags. The owner came across as immature and reactive, not someone capable of handling a job professionally. I was unable to verify proper licensing or workers' insurance, which raised major concerns about liability and accountability. If something goes wrong, it's unclear what protections -- if any -- are in place for the customer. Overall, this was a stressful and unsettling experience. Between the anger, the lack of professionalism, and the unanswered questions about legitimacy, this company is simply not worth the risk. Legal action will be taken!

A COMPLETE WASTE OF TIME, LUDICROUS SCAM, ILLEGITIMATE Before hiring, I reviewed the company's positive Yelp feedback and later noticed a troubling pattern: several glowing reviews appeared to come from individuals with the same last name as the owner or from accounts that strongly suggested personal connections (e.g., family members, romantic partners, or close associates). While I cannot independently verify each relationship, the pattern itself raised serious concerns about credibility and the authenticity of the company's online reputation. If accurate, this would be an inappropriate and misleading way to market services. My direct interactions with the owner, Mark Serenzia (chatgpt://generic-entity?number=0), were deeply concerning. Professionally speaking, his behavior was erratic, manipulative, and highly reactive. He consistently reframed situations to shift blame, deflect responsibility, and position himself as legally protected rather than focused on resolving issues appropriately. Conversations felt calculated, tense, and adversarial rather than collaborative. What stood out most was the pattern of behavior: aggressive communication, rapid escalation, and an apparent preoccupation with protecting himself instead of delivering professional service. Rather than addressing concerns transparently, he appeared to twist narratives to work in his favor. From a homeowner's perspective, this behavior raises serious red flags about accountability if something were to go wrong. Taken together -- questionable review practices, unstable communication, and a clear lack of professional boundaries -- this company feels like a lawsuit waiting to happen. I would strongly caution anyone against allowing this individual onto their property or entering into any agreement without extreme due diligence. read more

We had Cerenzia Fence install a new fence for our dog along with a gate across the driveway, and I honestly couldn't be happier with the result. Keeping our dog safe in the yard was the main reason we called, and they really understood exactly what we needed from the start. They came out for the estimate, walked the property with us, and gave great suggestions on the best way to fully enclose the yard while still making the driveway easy to access. The driveway gate came out perfect--solid, easy to open, and it blends in really nicely with the rest of the fence. The crew showed up on time, worked hard all day, and paid attention to every detail. You can tell they care about doing the job right. Everything is straight, sturdy, and looks great. Best of all, we can now let our dog out without worrying about him getting loose, which has been such a relief. They also cleaned everything up before they left and made the whole process stress-free. It's hard to find contractors this reliable and professional. Highly recommend Cerenzia Fence if you need quality work done right the first time. read more

Mark and his crew are the best. My property was a farily large and challenging project, and they handled it seamlessly from start to finish. They were professional, creative, reliable, and kind throughout the entire process. Even my neighbors commented on the quality and method of the installation and said they planned to hire them for their own fencing projects. Mark's character sets him apart. He is a compassionate honest businessman - something that I find to be rare. If you are looking for someone you can trust to stand behind their work and go above and beyone to make sure you are happy, Mark is the person to call. He puts customer's first, even if it could come at his own expense. I would never use another fencing company. I have already referred him to friends and family, and I am confident they will have the same outstanding experience with him and his team. read more

I've worked with Mark on multiple projects, including PVC fencing as well as aluminum and glass railings. Each time, he's provided competitive pricing and delivered neat, clean, and timely workmanship. What I appreciate most is his professionalism and responsiveness. On the rare occasion I had a question or wanted something adjusted, he was more than willing to accommodate and make it right without hesitation. Reliable, fair, and detail-oriented -- Mark has become my go-to for fencing and railing work. I would confidently recommend him to anyone looking for quality craftsmanship and a smooth experience from start to finish. read more

I recently hired Cerenzia Fence Co. to install fencing on my property. Mark was professional, knowledgeable, reliable, and reasonably priced. Completion was done in a timely manner and done exactly as discussed beforehand. My property was left in the same condition as it was found, clean and all debris removed. It was a pleasure to work with this company and wouldn't hesitate to, confidently, recommend Mark to my friends and neighbors, nor would I hesitate to call on Mark for my future needs. This is a great company. Thanks, Mark and crew, for a job well done! read more

This is the go-to fence company for the NY Tri-State area. They installed our fence two decades ago, and it's held up beautifully over the years. We recently called them back for some repairs, and just like before, their work was top-notch. Highly recommended! read more

Mark is so amazing he is so professional and personable he is honest and trustworthy you don't find these qualities anymore, if there was 10 stars I would give him a 10 for real star quality and my gate looks so beautiful! Thank you Mark read more

Extremely disappointed with this company. The owner displayed poor communication and a worse attitude. Further research revealed suspiciously positive reviews likely from friends, family, and their spouse. Look elsewhere! read more

Mark is such a humble person. Offered him a job to do my pvc fence and the job was done as expected. Mark took the time to clean up and went above and beyond on the installation. read more

Did incredible work with a very difficult landscape to work with, and an immaculate clean up. He also gave us the best estimate out of 3 companies. read more
