"Jack and his crew did a great job with the work we needed done which ended up being more complicated than we had anticipated. He charged by the job rather than the hour, which worked out well for us since his crew had to pull half the wires out of the electrical box to figure out what previous electricians had done in our condo. Jack and his crew were honest and efficient and I wouldn't hesitate to hire them again."

"Had GLP perform a panel upgrade as well as install a level 2 EV charger in the garage. Carlos was extremely responsive and accessible. Very helpfully walked us through every step of the process from estimate to completion, always explaining the work he was doing and answering our many questions. Then, the work itself was high quality. Also very friendly in person. Highly recommend."

FAQs for electrical wiring or panel upgrade projects in Oak Brook, IL

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.
