"Brenden did an amazing job trouble shooting a few three way switches we have had issues with. He jumped into the challenge quickly and was very knowledgeable with the project. He was able to troubleshoot it and find the problems that we had and fixed them. Very professional, reasonably priced and highly recommend. "

"Jesse arrived on time and answered all my questions. I don't know much about electricity but he explained everything in a way that I understood what he was talking about. He tested everything along the way and to my complete satisfaction. I'll be happy to hire him again when it comes time to replace my electrical panel this summer."

"Everything was smooth in terms of the project. There was a hiccup with the quote I got because they mistaken the installation as an indoor installation. But it was outdoors. We agreed on a price that worked (which was higher than initial quote). They did a great job and made sure inspection was done. Great job. I would go back for future electrical projects."

Customers say: Quick response

"Gary was so easy to work with. He listened to what I wanted and didnâ t try to scam me into anything I didnâ t need or want. As a single woman, I find at times that a male dominated field has some people who try to get extra money out of you by recommended additional work that I actually didnâ t need. Gary was honest and I have him as my go to business for future needs. I have also recommended him to colleagues at work!"

FAQs for electrical wiring or panel upgrade projects in Renton, WA

While homeowners with substantial electrical knowledge might technically attempt a subpanel installation, most local building departments require permits and inspections for this type of work. Professional electricians understand local code requirements, can obtain necessary permits, and ensure the installation meets safety standards. Given the significant safety risks associated with incorrect electrical work, most homeowners benefit from hiring a licensed professional.

A standard subpanel installation takes an average of four to eight hours. This timeframe may extend if you're installing multiple subpanels or adding specialized circuits like those for spa equipment. Factors such as difficult access points, complex wiring paths, or permit processing times can also affect the overall project duration.

Adding a subpanel doesn't directly reduce electricity consumption or lower your utility bills. A subpanel simply redistributes power from your main panel to additional circuits. However, organizing your electrical system more efficiently may help prevent overloaded circuits and the associated problems. For actual cost savings, consider energy-efficient appliances and lighting instead.

The appropriate subpanel size depends on your specific electrical requirements. Consider the number and type of devices you'll be powering, potential future needs, and the capacity of your main electrical panel. An electrician can perform a load calculation to determine the most suitable amperage rating for your situation, ensuring you have adequate power without overpaying for unnecessary capacity.

A main electrical panel connects directly to your utility's power supply and contains your home's primary service disconnect. It distributes electricity throughout your entire house. A subpanel, by contrast, receives power from the main panel and redistributes it to a specific area of your home. Think of the main panel as the primary distribution point and the subpanel as a secondary branch that extends your electrical system's reach.

While electrical upgrades aren't as immediately visible as kitchen or bathroom renovations, they can contribute to your home's functionality and safety. Prospective buyers often appreciate updated electrical systems that can accommodate modern power demands. A properly installed subpanel that provides additional capacity for workshops, home offices, or future expansions could be an attractive feature for certain buyers, though the direct impact on home value varies by market.
