"These guys came out and worked in the dead of cold in the winter in an old barn and got the job done. It was a good value for the price point. They aren't the cheapest but you wouldn't want that with a professional electrician. John has a good crew of people working with him and they'll get the job done. This was a 100 amp to 200 amp upgrade with a sub panel and electric car charger install."

"Guys were nice enough but it took them 3 days to "trouble shoot", claiming they took out and looked at all the outlets day one but couldn't find the issue and then had to come back a 2nd day and claimed they would need to cut a hole in my wall and then came back a 3rd day and found that it was an outlet issue. I couldn't get an explanation as to why it took 3 days to figure out this issue when they checked the outlets day 1. I had to pay over $1000 for work because they couldn't figure out the issue. I understand it can be hard to identify but to take out all the outlets on day one and then find the resolution was in the outlet 2 days later is terrible."

Electrical wiring or panel upgrades FAQs

Installing electrical service to a detached garage costs between $1,000 and $3,800, with the exact price depending on your specific requirements and the distance from your home. This project may include a subpanel installation if you need multiple circuits or higher capacity. The complexity of your electrical needs, the garage's intended use, and your location all influence the total investment required for a properly installed and code-compliant system.

Most local building departments require permits for electrical work connecting separate structures, with permit fees ranging from $25 to $200. Professional electricians are licensed to perform this type of work in most states, and they often handle the permit process as part of their service. Skipping required permits could potentially create issues with insurance coverage or future property transactions, making proper documentation an important consideration.

For safety and legal reasons, hiring a licensed electrician is highly recommended for connecting electrical service to a detached garage. Electrical work involving separate structures requires specialized knowledge of codes, proper materials, and safety protocols. While homeowners might handle certain aspects like trenching to save on costs, the actual electrical connections should be performed by qualified professionals to ensure safety, reliability, and compliance with local building regulations.

The timeline for installing electrical service to a detached garage spans from several days to a couple of weeks, depending on project complexity. The process includes planning, obtaining permits, trenching, electrical installation, and any necessary finishing work. Weather conditions, contractor availability, and permit processing times can all affect the overall schedule. Your electrician can provide a more specific timeline based on your property's unique characteristics and project requirements.

Underground electrical installations for detached garages tend to use conduit systems rather than direct burial cables, as conduit provides superior protection for the wiring. While specific installation methods may vary based on local codes and site conditions, professional electricians often recommend running electrical lines underground via conduit for detached structures. This approach helps ensure long-term durability and simplifies any future maintenance or modifications to the system.
