He identified the issue right away when I advised him of it and we took it back the next day for a quick fix. So glad we went with Nico. He has a six month warranty on his repairs.

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.

We just purchased our home last August and now there are holes all over our brand new home. I am afraid we may have to pursue this legally or make costly repairs ourselves.

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.

Got tuned into the need to check my fire extinguishers after lately seeing so many deaths and…read moredestruction by house fires in the news. Without an education about inspection or servicing my extinguishers, I just assumed the units would work when needed and I would know instinctively how to use them. So, 'attending to my home's extinguishers' never made it to my to-do list. After getting a brief education on youTube, I learned how critical fire extinguishers are to home safety. Since Fire Departments are so enthusiastic about smoke, carbon dioxide, and radon detectors, I was disappointed to learn that not only do they not execute recharging and inspections but the service rep had no referrals. Recommendations to homeowners regarding fire extinguisher protocols, inspection, and usage should rate the same attention as their smoke detector promotions. Workshops on when and how to use fire extinguishers should be standard in our schools, hospitals, airports, businesses, home owner insurer inspections, etc as well as part of our Fire Departments' community education programming, locally and nationwide. Think about the potential exposures to fire during and after impacts on structures by extreme weather events. Moreover, so many vehicles have recalls with warnings of spontaneous combustion while driving and/or when garaged. Even airplanes, electric vehicles, and electronic devices have increased instances of battery fires and explosions. Domestic airlines just established a mandate that all battery packs and battery-driven devices be displayed and NOT packed in cargo OR in overhead cabin luggage due to recent fires. Nonetheless, my online search turned up F&M FIRE PROTECTION with a five star rating for inspection and recharging fire extinguishers, among other services. This company should be on the Fire Department's resource list for local fire extinguisher services. Though I figured my units were too old to recharge, rather than default to an online purchase, my choice to visit in person was the right move. This location is a great value if you are in the market for fire extinguishers, inspection, and/or recharging. After shopping by browser, I found per unit rates to be same as online with the added value of receiving a full understanding of related data points you may not have considered. Though the building is tucked away in an industrial park, GPS can get you there without a hitch. Worth the side trip to be struck by the high-spirited, personable attention you get, delivered by a light-hearted team with a gallery of antiques on display.
