"They did an excellent job of installing the new panel at a reasonable price. Also they had financing options that were same as cash. I was provided some options of circuit breakers and the price with the options. The differences in breaker were explained and the code requirements for my area was also explained and compared to other local code standards. I was able to customize the options a little bit based on my needs and I have more space in the panel if I have additional requirements. Going from a box from the 1960’s to a modern solution mad a lot of sense. The installation was smooth with only a short time without power. Throughout the process, I was well informed of the progress. My family was able to work remotely from home during most of the install without too much disruption. (Used cell phone for internet and laptops while power was off.) They even installed a monitoring system for me to track the electrical use of the house. Overall they did a great job and I am very satisfied."

"Do not use this company. They will rip you off. The contract was for eight 300W LED 40 ft pole lights, but I caught them redhanded installing 240W. Who does that? Then, they broke my lock and broke into my sprinkler room which I saw on my video which they admitted. Then, Kolb sued me for not paying the bill which I disputed due to lost tools as result of the break-in. Who does that breaking into a customer's sprinkler room and not informing that they did. I had to catch them on my video. Not only that it took over one year to the work proposed work. TOTAL FRAUD. I will be going to court...."

Because installing coax outlets involves working around existing electrical wiring and confirming proper grounding, many homeowners prefer to hire a licensed electrician. A professional completes the work safely, secures the line behind the wall, and ensures the installation meets local code, which reduces the risk of damage or future repairs.
You still need a coaxial outlet for most cable-based internet services. The modem draws its signal from a cable line that terminates at a dedicated wall jack. Once the modem is online, your Wi-Fi router can broadcast the signal throughout the home, so the outlet’s location doesn’t affect wireless performance. If an existing jack is damaged or in an inconvenient spot, an electrician can move it or install a new one to maintain a strong, reliable connection.
Coaxial cable loses signal strength the farther it runs. A 50-foot length introduces noticeable loss, and a 100-foot stretch can drop the signal by roughly 30%. A weaker signal can result in a fuzzy picture or slower internet speeds. To maintain high performance, limit cable length whenever possible, select the correct cable grade, and route it efficiently. If your layout demands an exceptionally long run, an electrician can install an inline amplifier to boost the signal and maintain picture or data quality.
