"My experience with Apollo Electric was wonderful. I needed some normal electrical work done, and also some detailed more involved work. He handled everything with care as if it was his own home. He was very detailed oriented, neat, clean and very honest. Mike worked hard during the entirety of the job, I was very pleased and I would call him for any job I need involving electrical work for the future"

"Second time using B-Tec electric and I think now they are my go to electrician. I used them previously to upgrade my panel to 200 Amp and this time to hook up my new electric water heater. Both tasks were completed perfectly and fairly priced. I highly recommend B-Tec electric!"

"Outstanding & Awesome! Highly Recommend! We Canâ t find nearly enough words/great things to say about Mark/MD Electrical! My Husband & I are first time home buyers & we were scouring to find an electrician for home electrical upgrades including adding new wiring for our electric fireplace. Called Mark/MD Electrical & he was able to make himself available that very evening to look at the job & provided a quote within 24 hrs. Obviously we hired him! He got the job done promptly, explained everything in detail & even cleaned up afterwards! We appreciated all of that so much. Also, you can see that he actually enjoys what he does & will ensure that youâ re satisfied. A week later (after the initial job was done), my husband & I decided to call him back because we were inspired & hired him to do a small 2nd job that we thought of last minute, totally unplanned. We hired Mark again and he managed to squeeze us in & even worked later evening hours to get the job done because he knew we wanted to finish the sheet rock/close the wall. Mark, youâ re our electrician savior! The most sincere Thank you! Eve, Laz & Lili (canâ t forget the bird)"

"Iâ ve been working with Henry for a few years now. He replaced and upgraded my electrical panel, installed lighting outside my home, and installed lights in my basement. He is really experienced and very easy to work with. Since I donâ t know much about the technicalities of the work, he took the time to explain to me what heâ s going to do, how and by when. He always goes above and beyond to meet the timelines he set at the onset of the project and the quality of his work is outstanding."

"I connected with Bob on the phone immediately and did not hire 3 other pros who bid on the job. Bob was very competitive. The quote had to be revised after the fact and after hanging several fixtures however, Bob was very professional handling it and was a gentleman. I trusted both Bob and Chris alone in my home and felt very comfortable doing so. Bob, Chris and their team Rob A and Rob C were perfectionists and extremely competent. The team is very pleasant, professional and easy to work with. Bob and Chris are very reliable, warm and more than competent. Bob has been doing electrical work for 35 years and is up for any challenge. I would hire them in a heartbeat to do electrical work in my house and would highly recommend them!!!!"

FAQs for electrical wiring or panel upgrade projects in Denville, NJ

Yes, a licensed electrician is essential for this project. Running an electrical service from the road to your house involves connecting to utility power lines, complying with national and local electrical codes, and safely handling high-voltage systems. 

Licensed professionals understand proper wire sizing, grounding requirements, and voltage drop calculations needed for safe installation. Most jurisdictions require permits and inspections that only certified professionals can obtain. The safety risks and potential for property damage make this project inappropriate for DIY attempts.

Overhead installations are less expensive than underground options. For a 1000-foot run, overhead service costs between $8,000 and $15,000, while underground service ranges from $10,000 to $25,000. 

Overhead lines require less labor and fewer materials since they don't need trenching or conduit. However, underground lines offer better protection from weather events and aesthetic benefits. Your decision should balance your budget constraints with long-term reliability and visual preferences.

You might need to upgrade your electrical panel depending on your power requirements. If your existing panel cannot handle the additional load from the extended service, upgrading to a 200-amp service (costing $750 to $2,000) may be necessary. 

A licensed electrician can evaluate your current system and determine if an upgrade is required. Factors include what you'll be powering at the end of the line, existing electrical demand, and whether voltage drop over the distance will affect performance.

Running electric service from the road to a house requires electrical permits from your local building department, costing between $500 and $2,000 depending on your location. You may also need excavation permits for trenching work if installing an underground service. Your utility company will have its own application process for connecting to its grid. A licensed electrical contractor can handle all the necessary permit applications as part of their service, ensuring your installation meets all local code requirements.
