"Scott was very knowledgeable and helped me with some decisions regarding upgrades and new electrical work. I found him to be very prompt, friendly, professional and efficient. He did outlet repairs for me and also added some new lighting. The prices he quoted were reasonable and I am very satisfied with the work he did. I will be calling Scott for all future electrical needs."

Our electricians were polite and professional finished the same day. It was inspected passed and for the amount they told us. I would use them again."

"What a terrific experience we had with Mighty Bee Electric! Martin came the next day after we called. He was on time, clearly knows what he is doing and fixed everything for the estimated cost. And there was no upselling! I will definitely call him for any future electric work!"

"ELI was wonderful! He arrived on time, was friendly, thorough and quick. What really impressed me was ELI'S attention to the little details--he made sure no water, garbage got loose under the counter, used a mat to protect my floor/inside counter, cleaned up everything--even my sink--when he was done and, finally, put everything back under the counter where it was before he came! Above and beyond customer service! I will recommend AAA who anyone who needs drains unplugged! Also I like the company and especially the SERVICE so much, I'm meeting with a tech for another job--electrical this time. THANK YOU, ELI for your time, service and patience with my speech! much appreciated!"

FAQs for electrical wiring or panel upgrade projects in Longmont, CO

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.
