The N & D Security team (Sally, Perry, Darren, John, and David) is incredible. From my first phone…read morecall 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.

The…read moreservice was fine, a bit more expensive then other services available but it was convenient to keep it setup with them. We sold out house in Dec this past year and just found out we are locked into a contract until 2019. To break our contract I have to pay 80% of the remaining balance. Unbelievable! I guess it's my bad for not reading the fine print, but it's pretty shady to lock your loyal customers into extended contracts. Auto-renew for one year if you must, not 5-10. I also spent about 9k on wiring with American Home Systems when we built the house, so it's not like they were losing money on our deal. I would avoid this company at all costs.

Trebor Tech did an incredible job installing a server rack and running six network drops throughout…read moremy three-story home. From start to finish, they were professional, punctual, and clearly took pride in their work. What really set them apart from the other four companies I got quotes from was their attention to detail -- they not only ran all the cabling cleanly, but also repaired and painted the drywall afterward, leaving everything spotless. My home posed some challenges since there's no traditional attic access, but they found a smart solution by cutting a discreet access point and installing a clean, removable panel that looks like part of the original design. They even went above and beyond by installing a drop-down TV mount in my living room since my fireplace mantel sits too high for comfortable viewing. The entire experience exceeded expectations, and I wouldn't hesitate to hire Trebor Tech again or recommend them to anyone looking for quality network or low-voltage work.

The service over 10 years was fantastic. Fast forward, 2025. we decide to cancel partially…read morefinancially but home up for sale and wasn't taking equipment with us. Called to cancel, they needed proof equipment was paid off for early buy out promise. We have email proof and provided by supervisor in email we could cancel no termination fees. Two months, no service turned off. We had moved to new place. We call back, we need proof. We did this already, but they say they don't have it but offer two months free hoping our buyer if home would want it. we say okay but if at the end of two months house hasn't sold, cancel. They did not and drafted out our account. We call back, same mess different day. We submit documentation and forward previous emails. Time went by, they tried to draft again but we removed auto draft. Sent bill with late fee. Get on phone again and here we are trying to cancel since September 2025, it's mid April 2026, still not cancelled and they refuse to give us the months back they drafted and saying they have no record of verifying our payoff of equipment or cancellation. So I will never recommend them ever because cancelling isn't option. Seeking legal action now. We have names of cancelling department, emails and proof of payoff. Do not use them.

My experience with Vivint Security has been extremely disappointing. I recently sold my home and…read moremoved into a rental property where I am not permitted to install the Vivint alarm system. Even though I no longer own the house where the equipment was installed and cannot transfer the service to my current residence, Vivint continues to expect me to pay monthly for a security system that I cannot use and no longer have. I contacted customer service hoping the company would review my circumstances and provide a reasonable solution. Instead, I received very little assistance, understanding, or flexibility. I explained that this is not a situation where I simply changed my mind or decided that I no longer wanted the service. I sold my home, moved into rental housing, and am unable to install the system because of restrictions beyond my control. Vivint has the ability to waive the remainder of a customer's contract under certain circumstances, but the representatives I spoke with were unwilling to help or seriously consider my request. It is incredibly frustrating to be charged every month for equipment and services that are not available to me. A reputable company should consider a customer's individual circumstances instead of hiding behind contract language and continuing to collect payments for a service that cannot be provided. The lack of compassion and practical problem-solving from Vivint's customer service department has completely changed my opinion of the company. Customers should carefully review every detail of the contract before signing, particularly the cancellation and relocation provisions. Life circumstances change, homes are sold, and people sometimes move into properties where installation is prohibited. Based on my experience, Vivint may still expect payment regardless. I cannot recommend Vivint Security. Their unwillingness to provide a fair resolution has left me paying for nothing and feeling completely disregarded as a customer.

I can't recommend Alex highly enough. Not only was his work excellent, but what really set him…read moreapart was his quiet professionalism, positive attitude, and willingness to go above and beyond. I had been putting off a few electrical projects for far too long: (1) Installing a Nest Doorbell Camera (wired) (2) Removing an old ceiling fan and installing a new one (3 Replacing an overhead light fixture I had gotten a quote from another electrician about 18 months ago, and they made it clear I'd be on my own for any drywall repairs or cosmetic patching related to wiring the doorbell. So, I had zero expectation that Alex would help with that kind of work. But from the start, I was impressed by how Alex handled everything: (1) His pricing was clear, fair, and refreshingly reasonable--especially after a recent experience with a plumber who charged me way too much. (2) The doorbell wiring was not a straightforward job, but Alex got creative. He figured out a clever way to route the wires using an old security system, saving me the headache of more invasive installation. (3) The ceiling fan ended up being trickier than expected. I assumed a wall switch was connected to it, but it turns out it never was. Alex spent nearly two hours troubleshooting the setup, but never once complained. He figured it out and got the fan installed beautifully. (4) There was a mix-up on my end with which light fixture needed replacing. By the time I noticed, Alex had already removed a different one. He quickly and graciously reinstalled the original and replaced the correct one--without any complaints or extra charges. (5) What should've been a 2.5-hour visit turned into nearly 6 hours of work, but Alex stayed calm, focused, and professional the entire time. He didn't try to renegotiate the rate or push for anything extra. He just got the job done, and done well. And then came the part that really stood out. After a long day of work, Alex accidentally left behind a few tools. When I texted him the next morning, he not only came back to pick them up, but--entirely on his own initiative--he offered to patch and caulk some of the drywall around the doorbell camera. I had absolutely not expected this. Even more impressive? He didn't plan to charge for the labor--just the materials. I insisted on paying him for his time too, because it was only fair, and the work he did made a huge difference. While I still need to do a little painting, the result is clean, tidy, and better than I could've done myself. A few final highlights: - Alex went the extra mile to deliver a result that looked good, not just worked well. - He was kind and patient, even when my 5-year-old came home and started asking him questions, and when our yappy little dog barked at him. - He was professional and low-key, communicating with me via texts and calls so I could stay focused while working from home. It's always a little awkward having someone in your home for several hours, but Alex's demeanor put me at ease. Bottom line: This was one of the best contractor experiences I've had. Alex was polite, skilled, fair, and genuinely cared about the quality of his work. I'd enthusiastically recommend him to anyone looking for electrical work--and will absolutely reach out again for future projects.
