"We needed more power and Zach worked with CORE to get our new transformer installed. Great communication; very responsive. High quality work and attention to detail. He went over and above with our upgrade and install of hot tub. He even showed me how to operate the new hot tub! He is now my go-to guy for any electrical needs in the future! It doesn't get any better than this."

"Per my contract with Redrocks Roof and Solar, I am to notify them if I suspect my solar system is not producing per their design, and to begin an "underproduction claim". If underproducing, they will compensate for lost production. My system operational as of May 5, 2025, I contacted them in August 2025 informing them of above stated concern. Called 3 times without a response until finally tech came out with last second notice on 9/2/2025. Fortunately I was home, helped him find 9 out of 14 panels that were never wired in. Photos were taken/sent to Redrocks. Additionally, it was discovered a setting on the system phone app given to me to monitor system was not enabled, which they were supposed to explain in detail to me and never did. So for 4 months my system was only producing 33%, Brooke (owner) acknowledged in a live phone call on the spot. I never received parts warranty details per the contract, no response after emails and phone messages about all this. I DO NOT RECOMMEND!!!"

"Thomas' work is spectacular, and on top of that he's just a well mannered, good person. One of my favorite qualities about any contractor is their communication and promptness and Thomas also greatly excels at these. I hired him for a large kitchen remodel project that included a heated floor, dimable LED under counter/cabinet lighting, replacing existing lighting with dimable LED canned lighting, and of course all the outlet work for this remodel, which included a 220 for the range and some outlets that had USB charging. On top of the large remodel project, I also tacked on smoke alarm detector upgrade for the whole house (a code upgrade Thomas up sold me to, but I didn't mind at all), as well as a car charger in the garage. I will be calling Thomas for all future projects, as well as recommending him to family and friends"

FAQs for generator repair projects in Castle Rock, CO

There is often some confusion about the type of work these professionals do. They only work on electrical systems such as outlets, lighting fixtures and electrical panels – they aren’t appliance repairmen.

There are three types of electricians: Master, Journeyman and Apprentice. Electrical licensing varies quite a bit by state. Some have licenses for apprentices and some do not. Some have a master’s rank while others stop at journeyman. Despite the differences, they all require a minimum amount of experience and usually classroom time.

  • Apprentice electricians aren’t usually licensed and spend 4 years learning the trade. Throughout that time, they work on a wide range of projects to learn to become a Journeyman. They’ll do basic work like installing fixtures and replacing outlets all the way to assisting in wiring a home. Regardless of the type of project, they must always be supervised by a Journeyman or Master electrician.

  • Journeymen work without supervision. In a few states, this is the highest level available and they can do all levels of work from wiring a new home to installing a light. In some states, they need a separate electrical contractor license to run a business. In places with a master’s level, a journeyman can do all work besides design new electrical systems.

  • Master electricians usually manage a shop, design new electrical systems in new construction and oversee both Journeyman and Apprentices. They typically bid new projects. Though they focus on larger projects, it’s not unheard of for a homeowner to request a Master Electrician for a house call. If you do, expect to spend up to 25% more for the visit.

Generally, you don’t tip electricians, but that’s not to say they don’t appreciate it if you do. You can offer them something to drink or eat, like coffee and donuts. Most will appreciate it if you do.

The education and certifications required to become an electrician vary by state, though they generally follow this list:

  1. Apprentice

    • Does not always require a license depending on the state.

    • Learns on the job under Journeyman and Master Electricians.

    • Usually needs 4 years on-the-job training before they can test for a Journeyman license. Many states also require a technical degree to advance.

    • Always require supervision.

  2. Journeyman

    • Needs between 8,000 to 10,000 hours of on-the-job training and usually 500 to 1,000 hours of classroom experience.

    • Can usually supervise apprentices.

    • They can diagnose and repair electrical problems.

  3. Master

    • Achieved after an additional two years (4,000 hours) working as a Journeyman and taking the Master Electrician Exam.

    • Besides diagnosing and repairing electrical systems, they also design them. In most places they run shops and inspect Journeyman and Apprentice work.

    • Not a recognized rank in all states.

  4. Electrical Contractor License is an optional license in some states for a Master Electrician to run a business. Some states have this instead of the Master license.

Electricians make an average of $26 per hour but it ranges with experience and licensing. An apprentice may make about half that while a Master Electrician may hit closer to $40 per hour. This figure represents how much they make; not how much they bill. Their salary is only one component of their costs. They must also figure in overhead, taxes, equipment, insurance and several other expenses.

Leave electrical work to the professionals. Electrical systems are complex and potentially hazardous when not handled and installed correctly. If it were easy, it wouldn’t take 4 years to become a journeyman or 6 years for a master’s license. If you are determined to forge ahead yourself, understand home electrical safety before beginning any project.Even for simple common electrical projects, a licensed pro is best. Not only is it safer, but contractors guarantee and insure their work. Hire a professional to keep your home’s electrical systems functioning properly and safely.
