We just bought a house in Arlington, received a couple of quotes from a couple of different companies, not only was N&D competitive, they have gone above and beyond. The people that work here really care, the owner is very responsive, could not be happier with our choice! Highly recommend! read more

The N & D Security team (Sally, Perry, Darren, John, and David) is incredible. From my first phone call with Sally and Perry to the installation with Darren, John, and David, the experience could not have been more seamless. Initial Communication: Before settling on N & D for my home security system, I did tons of research, including research into all the big home security companies. Unlike other companies, N & D Security does not lock you into a long-term contract, nor did they try to upsell me on products and services that were beyond the scope of my needs. Rather, Perry readily identified what would likely make sense for my home, asked incisive and poignant questions about my home security needs, and carefully listened to and thoughtfully answered all my questions. He then diligently followed up with a recommended package for my home. Perry's attention to detail, follow-up communications, and responsiveness was impeccable. And I was all the more impressed given the fact that N & D is a small team that essentially operates as a family-owned business. Installation: The installation could not have been more seamless. John, Darren, and David arrived promptly. They installed the security system and had me up and running in little to no time. I was thoroughly impressed by the service--the N & D team went above and beyond anything I could have expected. For example, in addition to setting up my home security system, Darren helped set up our doorbell camera and even attempted to help install smart locks throughout my home. Upon the immediate completion of the installation, John carefully explained how the system operates, patiently answered all my questions, and even gave me his personal number in the event I had any additional questions. After Installation: After completing the installation, Perry checked in again to ensure that all our needs were handled and that our system was up and running. In addition, the N & D team was incredibly diligent in completing additional follow up work I had requested. In sum, if you are looking for a top-notch home security system, N & D is a no brainer. They are a pleasure to work with and I can genuinely say that choosing them for our home security needs was one of the easiest decisions I've made. read more

I am extremely pleased with the service I received and would highly recommend this local security company to fellow Virginians seeking reliable, professional, and high-quality security solutions. 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. read more

We had an amazing experience with this local, truly family-owned security company- N&D Security. So when 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. read more

I would recommend N & D Security. They were efficient, responsive, and great value. They responded quickly, tailored a plan of action for us, and were lower costing than other quotes that we gathered. Their technicians came out within days to modify the system in place upon request. They also effectively walked us through understanding the system. read more

I had been a customer of ADT (now Everon) since 2009, a legacy customer they have acquired through various mergers. The quality of service and price led me to search for a more local provider. I just switched to N&D Security and will be saving over $100 a month for a monitoring service with cellular backup. The switchover was painless and efficient and am very happy with the decision. And with their monitoring app, I actually have gained functionality. I wish I did this years ago. read more

This is one of the few times I've ever cross-posted my review from Google because I'm so happy with the service and product! N&D Security is awesome! I was hesitant about going with one of the big national companies, so I was thrilled to find a local security provider. From the start, Sally and Perry walked me through everything - Perry sent me so many detailed emails to confirm how I wanted to proceed and flagging the costs for me. The actual installation was great. The guys (David and his team) were super efficient, professional, and they explained everything to me. I love the tech and all the options the system provides for security coverage, and the app has been very easy to use. I'm very pleased with everything, and I'll definitely recommend N&D to anyone who asks! read more

N&D met my high expectations. I chose them because of their great reviews and they did not disappoint. Perry is very responsive and the technicians David and John were professional and courteous. Installation took just under two hours and David took the time to explain the system and technology to me. I called ADT for a quote and was put off by their overly scripted hard sales approach and did not appreciate that they asked me for the last four digits of my SSN and birthdate in order to provide discounts/specials. Additionally, once Perry answered all my questions, I was ready to have the installation done and his team came out in two days! Highly recommend N&D! read more

Phenomenal security company and the customer service is unbeatable. The difference between them and the larger, more well-known security companies is night and day. From the very first contact, Perry has been extremely responsive, ensuring I got a system for only what I needed and nothing more (zero pressure to buy any unnecessary extras), sending techs out right away if there was ever any sort of issue with the system, and following up on multiple occasions to make sure I was happy. I can't say enough about this company; they're great, honest people to work with, and I will recommend them to anyone I know looking for home security in the DMV. read more

The team at N&D Security, which includes Perry, Sally, Darren and David, all worked hard to make my experience a very positive one. They were all unfailingly polite and competent. They evaluated my needs, gave me a detailed explanation and cost of the proposed sytem, answered all my questions, set up a date for the work, and showed up on time. The installation was painless and Darren and David patiently explained how the new system worked. Perry answered a few questions after the install, and is in general very responsive to questions and comments. I highly recommend N&D Security for home alarm systems. They do excellent work at fair prices. read more

what a refreshing improvement from dealing with the last unresponsive corporate franchise providers of our security monitoring system. N&D set an actual appointment time, no trying to schedule around a four-hour window, and showed up right on time, completed the installation and followed up. How all providers should operate. read more

N&D is an amazing company. I recommend them to every friend who buys a home in the DMV. The will give you the exact equipment you need for your home and not upsell or over-secure your home, the monthly price is WAY CHEAPER than big corporate alarm companies, and when you need something you can pick up the phone and someone who you know answer and help you out. The monitoring relay runs through the same national provider that the big folks use and the equipment is the same that you can get from ADT or one of the big guys. My home is more secure and better protected at a lower price, and the people I deal with are super friendly and easy to talk to. THEY ARE THE BEST IN THE DMV AREA HANDS DOWN. read more

N&D recently installed a security system at our new home. The experience was a pleasure from start to finish. Perry and Sally treat you like family and don't oversell you. We also loved that their package includes maintenance on the system at no extra charge. The equipment is high-quality, the same that ADT uses, yet comes with the personal touch of a local company providing personalized service, and at reasonable rates to boot. We recommend N&D to anyone in the Northern Virginia area looking for a high-quality home security system without the hassle. read more

Fantastic customer service, responded quickly and provided a detailed summary of what was offered as well as the prices associated. The system install was great and the team at N & D Security take value in their work by providing an excellent service. read more

New customer and the service has been great so far! From my initial interaction to the installation, the service has been personalized and very responsive. Their team went above and beyond during the installation as well and were very professional. Highly recommend! read more

I've had some form of home security for decades, and when I moved three years ago, I wanted a company that answered the telephone with a human being, not prompts to "press 1", or a huge company where my rep was in Idaho but claimed to know about risks in my new neighborhood. I found N&D, a family run local business. From the start, they impressed me. They didn't try to sell me the most expensive system, just one that comprehensively covered my needs and potential risks. And when they say they are a family business, they aren't kidding -- Mom answers the phone. And then they treat you like family. It doesn't get any better than that. read more

Even among 5 star reviews, these guys are some of the best. I needed an updated/working security system in the house we recently moved into. From start to finish, these guys were great. They do what they say they will when they say they will and they respond to inquiries promptly and thoroughly. Their value, service, and responsiveness is top notch. N&D was able to use what I had in place for sensors (for the most part) and added and updated where necessary. Unfortunately, they had a supply issue which delayed my installation a couple months, but eventually figured out an alternate solution and the system got installed right after they got what they needed. I had a minor issue once installed which they fixed it a day later and I had one sensor they didn't have the tools to install with everything else. They said they would get it done in a couple weeks and did just that. I am really pleased with the overall experience and assume I'll need them to update/upgrade the system down the road if I am here for a while. I know it will be smooth sailing if I do. read more

I chose N&D after reading the Yelp reviews, and I am so happy I went with them over one of the big companies. They respond promptly, and were really flexible even though I rescheduled the appointment time several times. The person who installed the system, Darren, was extremely efficient and polite, and really took the time to explain the system to me. And their prices are MUCH better than ADT. The whole team is just an all-around great group of people, and they made the security installation the least stressful part of buying a new house. I 100% recommend them. read more

Headline: The Kindest, Most Knowledgeable, Prompt-est, Fairest-Priced Security Folks One Could Imagine -- and with all the Tech You Could Want. I recently bought a home in Fairfax and went through a rigorous process through the "big" players - from Vivint and Brinks and ADT to a handful of others. I spent hours and hours and always felt as though -- well -- something just wasn't adding up: too expensive, too unsure, wouldn't have a person to talk to, etc. etc. There was always "something" that seemed to miss the mark. On a lark, I Googled the name of the company whose sticker adorned my alarm panel "N&D". Well let's just say that was the best piece of luck I've had in some time. From my first interaction with Sally, everyone (Perry, Gary, Francisco) has been attentive, kind, timely, helpful, knowledgeable, generous with their time, reasonable, etc. The list goes on and on. They set me up with exactly the level of security I wanted -- not more and not less -- and didn't hard sell anything. When there was a suggestion that they thought might be useful, they made it, but again without any pressure. And their prices are SO REASONABLE. Use these guys instead of Vivint and save yourself a boatload on the front end and on the monitoring across time. It's a no brainer. Any questions I have -- Perry has answered each of my emails in no less than 90 minutes. I can't say enough wonderful things about this company. HIRE THEM! read more

We saw N&D's great customer feedback on Yelp and decided to give them a try ourselves. Perry, Gary, Francisco and Sally were so helpful throughout the installation process. They followed up and resolved our sensor issues due to our walls blocking signal strength. I can't thank them enough for their professionalism and pro-activeness. I highly recommend their security services. read more

N&D is a great, family owned security company in the DC area that was fabulous with myself and my roommate in moving into our apartment in NW DC. There was an existing, outdated system that they were able to use, which they updated for cheaper than reinstalling the whole thing, put alarms on every door and window, and explained to us how to use the corresponding app to set the alarm if we needed to be out of the house. Installation was quick, efficient, and when my roommate and I had a question they ALWAYS answered. The one time we had a false alarm (key mix up with the rental company) police were called efficiently, emergency phone tree was activated, and there wasn't a charge or issue on our end with the service. After a year and a few months, the only reason we are ending service is because we are moving, and we will be wholeheartedly recommending the company to the rental management company. I wanted to support a local company when I chose a security provider, and N&D exceeded expectations with their service. I could not recommend them more! read more

Locally owned and operated, easy to work with and get a quick response if you have questions, highly recommend.

I reached out to N&D on a Sunday, not expecting a reply until Monday at the earliest. Perry answered me within an hour. The responsiveness has been outstanding - I've never waited more than a few hours to hear back, even if it didn't require an urgent response. Perry was able to help me understand the cost and compatibility after just a few emails. Once scheduled, Darren showed up on time and was very pleasant to work with. He made sure we understood every facet of the system. Although the commitment is only for one year, I'm sure I'll continue using their services for years to come! read more

The two brothers who installed our system clearly love what they do and know what they're doing. They displayed attention to deal installing the product and loads of patience showing us how to use it. In addition, they were delightful to talk with. We were left with the feeling that our safety in this new home (and town) are in the best of hands. Many thanks and looking forward to years of your service. read more

After our neighbor told my wife that there was a stranger walking around the neighborhood and taking pictures of home, we decided that it was time to install a home security system. At first, I went the traditional route, calling up reps from the big national providers - ADT, and such. The two biggest problems with what these companies offered were: a) contracts that would lock you in for several years with steep monthly payments. I know based on my past experience how hard it is to get out of those contracts. The low monthly payments that these providers advertise will quickly go up as you start adding necessary features; b) expensive professional installation - they were asking hundreds of dollars for putting a few sensors and a control panel in place. I stumbled upon N&D Security on Yelp and decided to give them a call. I spoke with Perry and was impressed by the customer-focused attitude, quick turnaround on a proposal, and competitive pricing, without the long-term contracts. The installation of the system was fast and professional. And finally, I really like the fact that I know who I am speaking with on the phone when I am calling N&D - security is a very personal topic, so it is good when you have a company who takes it personally on your side. read more

I recently bought a home in DC and came across N&D Security when looking for a security system. As a new home buyer, the amount of information out there about security systems can be so daunting! From the get go, N&D was professional, friendly, and quickly responded to my numerous questions. They made the whole process extremely personal and came out to do a consultation, which was so helpful for a security system novice. The install was seamless and the team was excellent to work with. They gave me a wealth of information and cell phone numbers for any questions. Their accessibility makes me confidant that they will be there for any questions along the way. read more

I just wanted to give a quick positive shout out here. Often in DC you don't know exactly what you need, you just want to talk through your problem first and explore the issue and gather some info. I emailed N&D through their website this morning and got a very thorough reply to my issue and detailed recommendation via email within an hour. It was clear that Perry took the time to consider my needs and reply with really useful, helpful advice. From just that interaction alone and the help I received, which was valuable, I'm giving these guys 5 Stars. I wish everybody in DC were this helpful and responsive. read more

We have had N&D running our home alarm system since late 2020 and they have been so great, so quickly responsive whatever day of the week to whatever question may arise. Gary, Perry, Andy and Francisco have all provided us great service. Francisco recently came over to reinstall some newer mini sensors and it was probably one of the most efficient, professional and polite worker visits to our home I can remember. read more

Very pleased with the work Andy did while installing my security system. He was very professional, personable and efficient. I got the feeling that their employees care about what they do and take the time to get to know their customers. I felt that they went the extra mile to provide support even after installing the system. I had a question and within minutes Andy answered my call and even stopped by the house to make sure everything was working the way it should. This is a top notch company that I highly recommend. Happy to have found them and to support a small business! read more

The entire team is wonderful. Personable, knowledgeable, patient and answered all my questions. They are professional and it is wonderful supporting a small business. They worked with me on cost as well which means a lot to me. I can't recommend them enough. Thank you so much to Perry and team!!! read more

I wanted to do airbnb in my spare bedrooms. After hearing safety concerns from my mother, I asked yelp about security options. Perry was quick to respond and suggested a Total Connect alarm system and affordable payment plan that would be optimal for my situation. Darren installed my system in under an hour & clearly showed me how to use it. Total Connect 2.0 is extremely simple and I am able to easily give my roommate access to the system. Thus far, I've had a great experience with N&D and I strongly recommend their services. read more

Excellent service and system - Perry was extremely responsive and forthcoming about pricing. He provided a very accurate assessment of equipment needs just based on photos from the house, no walk through required. Francisco the technician was prompt, quick, and helped remove some of the old equipment for no additional charge. I've had a few follow-up requests - adding another sensor, system issue - and Perry has been highly responsive in troubleshooting, even coming over himself at one point to help. Would highly recommend for both the quality of the system and the level of service supporting it. read more

Great company that is customer-focused, responsive, and very knowledgeable. Perry provided a clear and fairly-priced system and the technician Darren showed up on time, took me through the installation process thoroughly, and both of them gave me follow up calls to ensure all was well with my system. read more

We have really loved our security system with N&D! Bypass the larger companies with years of locked-in contracts for this honest family-owned security company. Communication and customer service are top notch... We had an in-home consultation the day after we reached out, and then a technician at our house a few days later setting up our system. Everyone has been helpful, polite, easily reachable and knowledgeable. Look no further! read more

I recently purchased my first home in Washington, DC and I wanted to have a security system installed before I moved in the following week. I had a not-so-great previous experience with ADT but I didn't know any local alarm system installation companies. I contacted N&D Security for an estimate based on my research on Yelp. Gary was able to come out within two days of me calling to set up an estimate and completed my install a few days later (prior to my move-in date, as promised), along with Andy's assistance. Everything was installed quickly and they were very neat and tidy. Andy was even nice enough to help me change the faceplate of my thermostat once he finished the install, which saved me having to call someone else (I'm pretty handy but the millions of wires were intimidating). By way of update, I've had my system for about two months now and I was having a communication issue with monitoring unit and the iPhone app (did I mention you can set your alarm from your phone? Amazing). I called N&D to advise them of the issue and Andy called me back immediately. He gave me his cell phone number and told me to call him whenever I was home and available to troubleshoot the unit. Given my work schedule, this was at a very random time in the morning about a week after I called initially. He walked me through about 15 minutes of troubleshooting and was patient while I fumbled through getting the faceplate off and cycling both my wireless router and alarm system. Everything is working perfectly again. And, unfortunately for Andy, I've saved his cell phone number in my phone! You can tell by N&D's accessibility that it is a family-run business -- whether it's trying to get an install done quickly or resolving an issue with the unit, they are super responsive and helpful. read more

When my former security company went out of business, I looked for a new company to provide my home security. After investigation, I called N&D and had them come out to look at my place. I was very impressed by the knowledge of the business and how to switch over to their services at a moderate cost. The installation was very smooth. It has now been nearly six months since installation, so I have had occasion to have a few interactions with N&D as a regular customer. When I call them, I get extremely knowledgeable people who can sometimes tell me how to program my system to fix a minor problem I have, but who have the full range of expertise at N&D to call on, if needed. N&D shows what can be done with a local family business to outperform all of the big boys in the home security space. I am very happy with them as a company and with the security they are providing to me. read more

We had a great experience with N&D Security. We were able to coordinate our installation with our closing time effectively and efficiently despite being over the holidays, and so we were able to have our system up and going for the first night we owned the house! Andy, who installed the system, was very knowledgable and was able to get everything done quickly and easily. He even pitched in with some great advice on other parts of the setup for us! They have always been super-responsive, and easy to work with. Would recommend! read more

My sister recommended this company. Now I have been a customer for over 8 years. At first I used their services in my condo. I was so pleased that after I got married and moved I requested them to install a system in my new location. The business is run by professionals who care about the quality of service. Installation was simple and completed in a timely manner. We are satisfied customers! read more

As a new and first time homeowner, all of the great reviews for N&D made them my first call when looking for a home security system. Perry and his team were amazing throughout the entire process from being extremely responsive, thorough in explaining our options, and going above and beyond during the installation process. I'm happy to partner with N&D and highly recommend them. read more

I continue to be impressed with how quickly Perry responds to my questions over email. I wish there was more stuff we could hire them for
