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.

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.

For me it's those two things that really stand out. Customer service and "it just works." In terms of customer service, it's hard to do better. The company's response time to questions is very fast. That's pretty much what you want. As for "it just works," the Alarm.Com system and equipment they are a dealer for really gives you peace of mind. It's actually secure. I could not be more pleased to work with and recommend the company.

In spite of what they told me two months before upon an inquiry I made. Instead they continued to debit my account. There is no way to stop it from your bank. Be aware of the scam and of their lies. When I cancelled with a form that I have to fill out, there was no acknowledgement. They still debited my bank account. They argued that there was a 3 days cancellation policy; this 3 months after my 3 year contract has ended. I have to yell for them to promise a refund for only 1 month. I am holding my breath. If this goes on, I will take them to court.

Rob and his colleague installed ethernet throughout our three-story townhouse (7 drops in total). Like another reviewer, we previously had ethernet only in the basement, resulting in poor Wi-Fi coverage on the upper levels. Regarding Trebor Technical Solutions, I wholeheartedly echo what others have shared. During the consultation, as Sriram (2021) observed, Rob "took notes of the locations where I wanted the drops, estimated the length of each run from the networking rack, and how the drops would be wired, carefully noting the number of cuts needed." Indeed, watching Rob in action is impressive--you can see him map, anticipate, and solve problems, as if he can "see" behind the drywall, identifying the cleanest and most efficient pathways. Sriram also noted Rob's "attention to detail deserves special mention, from planning the project to execution." I agree completely. Chaz (2024) wrote, "My experience with Trebor Technical Solutions was top-notch. The owner, Rob, went above and beyond." Absolutely. Rob left our townhouse better than he found it. Originally, ethernet entered through a hole in the wall--Rob repaired that neatly. He also removed unnecessary coax cables, replacing those plates with new ethernet plates. As reviewers' pictures show, Rob meticulously labeled each line with its corresponding room. Dan (2022) shared, "Rob is a pleasure to work with and makes everything easy. He pays close attention to details but also makes amazing recommendations." Couldn't agree more. He has a high work ethic and high standards. Todd (2022) wrote, "There's every reason you should immediately choose this company. Rob, the owner and a worker bee, is highly motivated to do right and technically trained by several mainstream internet and TV companies. He is extremely responsive and an awesome communicator." Rob's background (having worked at major companies) and continued work experience (providing expertise and skill to a variety of clients) are indeed impressive. Kyle's (2021) general contractor remarked on "how astonished he was with the gentle and delicate approach Rob took to making cuts in the drywall. Even though I was running drops across three floors and opposite sides of the house, Rob made only the smallest of cuts in the fewest places and did an excellent job patching up the drywall." Exactly. These were also my observations: Rob accomplishes tasks effectively with minimal disruption. Notably, he expertly repairs drywall cuts, leaving them paint-ready--a service many contractors overlook, as Sriram (2021) mentioned. Finally, Rob's patience deserves special mention. He patiently walks you through each step of the process at the level of detail you prefer, answering questions thoroughly--from the initial consultation through to completion and beyond. It was remarkable how patient and kind he was when explaining the system, piece by piece, and assisting us in setting everything up. We're grateful to have met and worked with Rob and his colleague. If you want commercial-grade quality and craftsmanship in your home, you've found the right team.
