"Top rate Company, they replaced my electrcal panel and did my pool bonding in Sept 2024. Ryan the Electrician was very professional, prompt and explained everything in detail.

"We initially selected Greenleaf Electric to do a circuit/breaker switch upgrade for a new oven based on their outstanding reviews on Angi, replacing our previous Master Electrician who had retired.  Everything that you read in their reviews is true.  Gill is highly competent, experienced, professional and has great communication skills; he's also focused on safely and informing his customers about every aspect of their project.  In the case of the circuit/breaker switch, he determined that with some minor adjustments to the breaker box wiring, the circuit to the oven would not have to be upgraded, saving us several thousand dollars.  We've subsequently had him do a number of smaller projects, all on time and at/under his initial estimates.  Highly recommended!"

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.
