I was looking for security monitoring company that really cares about their customers. I shop around and talked to several companies. Among all of them N&D was the one who really cares about customers needs. Perry was really helpful and kind. Even though I had a lot of questions, he explained everything patiently. Technician who install the panel, he was great also. All of N&D's employees must be great. Thank you.

I've been a customer of N&D Security for a year now, and couldn't be more pleased. From initial consultation, to installation, and billing, Perry & team are knowledgeable, transparent, and customer focused. About 6 months into my service contract, the control panel started malfunctioning. Perry responded to me immediately. Within 24 hours, they had swapped out the control panel with a brand new one -- free of charge! I put a high premium on customer service and quality products, especially when it comes to the security/safety of my property and family. N&D has exceeded my expectations.

My sister recommended N&D Security. 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!

N&D Security was a pleasure to work with and did five-star work installing a home security and video monitoring system in our home this past weekend. Outstanding communication, planning, and execution throughout the process. On the day of install, a four-person team of very personable and professional gentlemen arrived precisely on time and worked diligently to complete the install ahead of schedule. Their finished product is incredible and clearly reflective of their expertise and experience in the industry. We strongly recommend N&D and hope to business with them again in the future.

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!

We used N&D for years back when we lived in the DC Area. Always reliable and there when you need them.

I've used the N&D guys since 2014. They have been wonderful! Call to trouble shoot; turn off accidental alarms; and alway send you new batteries. Recently either my fire alarm or CO alarm has been making high pitch noises. We went though trouble shoot and they even sent me new co alarm to test. But something was still making noises. N&D was cool and sent a technician to trouble shoot. He was very patient.

We tested both fire alarm and co Alarm. It turned out to be the hard wired fire alarm and has nothing to do with N&D. The guys are still nice enough to come out and help with the install. Great customer Service!

These guys are the best. We've lived in different cities and we moved here in 2017. Wanted a local provider but really on top of things. They are perfect for the job. They don't oversell but will accommodate what you need. We put in door sensors and lots of window sensors and some glass breaks. Love a new panel which is much easier. I would only go with N&D. Experts on the phone. We did have one problem using the guest code on our box but we worked it out.

I am so happy I went with N&D 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.

Excellent and accessible customer service, prompt responses to my many questions. They were able to take over my previously installed security system without 'installer codes' which all the other companies were making a fuss about. I have an app to turn the system on and off.

We are very happy we chose N & D Security! They are very responsive, reasonable and easy to work with. When we requested for a quote, Perry responded promptly and we were able to schedule our in-home consultation soon afterwards. During the in-home consultation, we appreciated that they provided multiple options and did not push for more than what we felt our security needs were. The installation went smoothly and quickly. Further, the N & D Security system is intuitive and user-friendly. We highly recommend N & D Security!

My wife and I recently moved in to our condo and had multiple companies out for estimates on various security systems. Most of the salesmen seemed like they were trying to sell us the most expensive items even if it really didn't fit our needs. Perry from N&D was the opposite--he first asked us what we wanted, and then helped craft a system that fit our needs. Darren came to install the system and was very knowledgeable and worked quickly and proficiently.

Both Perry and Darren were extremely professional throughout the whole process, and my wife and I feel very safe in their capable hands. I would definitely recommend N&D Security to any of my friends or family in the area.

N&D Security provided 5-star service. We moved into a newly built home and needed to plan/design and install a security system. Perry was easy to deal with during the design phase, and the quote came in as very reasonable. The installation process was timely and went smoothly, and the workmanship was of high quality and not very invasive to the look of the new home interior. The post-installation system set-up and follow-up was very professional and N&D overall was a pleasure to deal with. I highly recommend N&D.

N&D Security has been a great company to work with from our initial quote to the final installation. They were extremely responsive and fast acting and we had our full system installed within the week. They have a personal touch and have been in operation in the area for some time. Their local focus is a welcome departure from much larger security companies who treat you like a number and try to lock you into a long term contract with hidden terms and frustration. N&D's price and contract structure was among the most, if not the most, reasonable of any security company in the DC area and we highly recommend them to anyone. They seem to really care about their customers.
