We had an amazing experience with this local, truly family-owned security company- N&D Security. So…read morewhen you call the company, owners Son-Mom duo (Perry & Sally) are going to pick up the phone. From the very first call, they were friendly, knowledgeable, and made us feel comfortable choosing them. There was no upselling, in-fact Perry convinced me to drop some unnecessary equipment (which would have otherwise added to the invoice price). The installation went smoothly, and the team (David, Nathan and John) took their time to explain everything clearly and answer all of our questions. What really sets them apart is the support after the installation. Anytime we've had a question or needed help, they've been quick to respond and genuinely happy to assist. The owner, Perry, dropped by a couple of days after installation to help us out on an issue. It's rare to find a company that truly cares about their customers the way they do. It feels great supporting a local family business, and we feel much safer in our home because of them. We did thorough due diligence for a couple of months and are happy to work with N&D Security. Please don't consume your time in unnecessary google searches, look no further and select N&D Security for all your security needs. We highly recommend this company to anyone looking for reliable, honest, and top-quality security service. Thank you N&D Security family from Chaudri family.

From the initial coordination with Perry, with whom I was in contact with to set this up, through the final installation, the experience was excellent. The technicians, John and Nathan, were outstanding: professional, courteous, respectful of my home, and exceptionally knowledgeable. Although I was in meetings for much of the installation, they worked efficiently and independently, and everything was completed seamlessly. Their expertise and attention to detail were evident throughout the process. The system itself is excellent, and the installation was done with great care (and for an affordable, reasonable price). Most importantly, I now feel significantly safer and more secure, which is exactly what one hopes for when investing in a home security system. Choosing a trusted local company made all the difference. The personalized service, professionalism, and commitment to quality truly set this team apart. I am very glad I selected them for my security needs and would not hesitate to recommend them to anyone in Virginia looking for dependable, top-tier service.
