Recently, I hired N&D Security for a security system installation, and the experience exceeded my…read moreexpectations for several reasons beyond their excellent reviews. First, the company responded quickly and professionally with clear, factual information. More importantly, I left they genuinely prioritized the customer's interests. Unlike some larger companies such as ADT, they were willing to work with and upgrade my existing system rather than push for a completely new installation. As a result, I was able to reuse most of the existing wiring, which significantly reduced the overall project cost - nearly cutting some competing estimates in half. The positive first impression carried out throughout the entire project. Both, the technicians and the owner were polite, responsive, and professional from start to finish. There were no gimmicks, hidden cost, or surprises = just quality work delivered exactly as promised.

I strongly advise anyone considering working with Monica Escala to look elsewhere. My experience…read morewith her has been nothing short of a nightmare, and I feel obligated to share it to prevent others from going through the same. I hired Monica in December 2024 to install: 28 security cameras A sound intercom system with 18 speakers 5 access control pads integrated with the fire alarm system As for the security cameras, she agreed to install 28 after reviewing my architectural plans but only installed 16--and did so carelessly. Wires were left hanging, ceiling tiles were damaged with large holes, and I was never given access to the security system, while she retained full access and was apparently monitoring the premises without authorization. The cameras themselves were cheap, low-quality models from Amazon (under $50 each)--completely unsuitable for a commercial setting, despite charging me for a professional setup. I paid her the full contract amount for this portion, and she has yet to complete the job or give me access to recorded footage. Despite paying her half of the contract amount upfront, she never delivered or installed a single access control pad. Even worse, she had no clue how to connect them to the fire alarm system--something that should have been fundamental to her scope of work. I had to bring in my fire alarm vendor and general contractor to explain to her how to do her own job. Still, nothing got done. Regarding the sound intercom system, she was supposed to install 18 ceiling-mounted speakers. Instead, she purchased cheap desktop speakers (less than $30 each) from Amazon, dumped them on the floor, and suggested installing wall shelves to mount them near the ceiling--completely unprofessional and unusable for a public facility. Meanwhile, she continued demanding more money and delayed my entire project by over five months--from December 2024 to May 2025--causing serious disruption and financial loss. To make matters worse, she repeatedly entered the property without my knowledge or permission, even after I explicitly told her not to. She frequently asked the building's front desk for access, showing a complete lack of respect for boundaries and professionalism. Monica Escala has shown a complete lack of expertise, ethics, and professionalism. She overpromises, underdelivers, delays critical projects, uses substandard materials, and ignores basic contractual obligations. In my experience, this was nothing short of a scam.

Once I realized that, the motivation to return them magically appeared, front and center! Living in DC, I dreaded the process of loading up my cat in a garage then struggling to find parking at any of the DC locations. So I waited until the weekend when I would be visiting my family to bring it to a location in MoCo where I knew at the very least, parking would be easy. As soon as I was approaching the door with all of my boxes, a gentleman working there came to the door to open it for me and help me with the boxes. That was so appreciated - and showed that they're proactive and not just going through the motions. He was able to then immediately get to work with updating my account and ensuring the equipment was accounted for. He even gave me a card should I have any issues with my current modem or if I needed to set anything up differently when I move. For something that I was dreading for months in anticipation of parking challenges and poor customer service, I left elated to have received such great customer support and to have this tasked crossed off my to-do list!

To be perfectly…read morehonest, Xfinity would not have been my 1st or 2nd choice (based on experiences from other folks), but it's the only company that provide service (or is the only one allowed to provide service) to my apartment building. First, unless you arrive to this location as soon as they open, I highly recommend making an appointment. Overall, I thought the person who helped us was pretty knowledgeable of Xfinity's products. I get that it's their job to promote Xfinity's products and make recommendations, but I was a bit annoyed that the team member was somewhat pushy with trying to have us change our cell phone provider. Ok, it's fine to mention Xfinity's cell phone plans, but when the customer tells you they are not interested, the team member should let it go - NOT bring it up another 3-4 times during the conservation about something else. After about 30-45 minutes, we left the store with our products. Unfortunately, we had to wait a couple of days to get fully set up because a technician had to update some things in our apartment building. In general, we have not had any major problems with service. The home Internet prices seem to be in line with other internet providers in the area.
