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.

Could not be more pleased or impressed. Rob is a professional's professional--immensely…read moreknowledgeable, careful, thorough, and a pleasure to be around. Look no further for a job done right. 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.
