Thumbtack customerOct 2026

Obi went over and beyond installing 3 of televisions. He was very responsive and communicated exactly when he would be there in install them. His work is phenomenal, so much so, I’m going to have him back to install more TV’s. I highly recommend his services!

Thumbtack customerSep 2026

Obi was amazing! Very friendly, responsive, and punctual. He fit us in very quickly, and did the most thorough job out of anyone I’ve hired on Thumbtack. He even cleaned our TV and hid the wires, while still giving us a discount. He was done within 10 minutes of arrival. I would totally use JELNIC again!

Thumbtack customerJul 2026

Genuinely impressed with the response time, quality, and speed of work. Solo work mounting a 75 inch TV and a 43 inch TV. Requested service around 8am and had same day mounting at 2:30pm, work done by 3:15pm. Cleaned up as he went and provided a TV mount for the smaller TV. 10/10 would recommend!

Thumbtack customerJul 2026

Obi’s work was excellent and pro active in that I had wrong size cable covers and shorter cables purchased from Best Buy. He had everything that was needed. He completed a television installation started by Best Buy and also a second one. I will need him once again very soon. TY, Obi!

KaRon S.Aug 2025

I needed help with mounting a tv last evening and they were so quick to respond and came out same day. Also helped hide the wires on the wall.

Jamie S.Jun 2025

Fantastic service! Exceeded my expectation and the new TV and surround sound are great! Will use again soon!

Gina W.Apr 2025

Obi responded to my request within minutes and was very responsive. He took the time to answer all my questions, while ensuring to ask the needed questions on his end for the project. Upon arrival, they put on their shoe covers and got right to work, checking in with me as needed to ensure they were doing what I wanted. The type of wall I had was not what I expected, but they worked through a solution for the wires. Although different from the original ask, I was very happy with the result.

I recently had JELNIC and his team install CC cameras at four locations in my home and set up NVR system. They did an exceptional job, working efficiently and resolving all the complex issues with ease. Their expertise in networking and smart home installations is truly impressive. The team worked quickly, professionally, and ensured everything was set up perfectly. I would highly recommend them to anyone looking for similar services. This is definitely a five-star service!

Obi was excellent! He had a very fair price and went the extra mile with no complaints. I had a doorbell issue with the wiring and he troubleshooted it with ease. The camera installation and TV mounts are perfect. He is a great guy! Thank you Obi!
