"I recently received a job offer that required me to move across the country, so I needed to get my house ready to sell in a very short period of time and needed a panel upgrade. Breeze Electric worked with me to get the job done quickly, efficiently, and in a manner that my wallet certainly appreciated, especially since I was getting ready to move 5 states away. I truly appreciate how easy the process was."

"Was quoted 12000.00 or so to repair all sewer pipes under crawl space.When I thought work was completed, the repairman came into home holding copper pipes.said they found 4 more leaks and charged me another 4000.00 or so.Also entrance to crawl space not completely covered when work was completed.This will allow animals ,my cat entrance to the crawl space.I had given a good review for this company,but on further review and time to rethink the process I would not hire again.I realize this was a tough job & they spent 4 days here but not happy with the additional $4000 charge,nor the entrance to crawl space not repaired properly ."

"I had an estimate done on some electric work, and James Pinson did an excellent job. He was very thorough, clear with his suggestions, and the pricing was very competitive. Based on James's visit and the estimate he provided, I chose Mr. Electric to complete the work."

FAQs for electrical wiring or panel upgrade projects in London, OH

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.
