An electrical panel is the main hub that distributes electricity throughout your home. It houses circuit breakers or fuses that protect each circuit from overload. If your panel is outdated, undersized, or unreliable, it’s time to consider an upgrade—and that’s where Mainstream can help.
If your lights flicker, breakers trip often, or you’ve recently added new appliances, it’s time to have your panel checked. Older panels may also feel warm, make buzzing sounds, or have rust or corrosion. We can assess whether a repair is enough—or if an upgrade will better protect your home long-term.
Embarking on a home renovation or addition is an exciting venture that can significantly enhance your living space and property value. However, it’s crucial to consider the capability of your current electrical system to support these new demands. At Mainstream, your safety and the efficiency of your home’s electrical infrastructure are our top priorities. Here’s why an electrical upgrade might be essential for your renovation project:
Don’t let outdated electrical systems hold back your renovation plans. Contact Mainstream today to ensure your home is prepared to meet the demands of your exciting new project. Our commitment to quality, safety, and efficiency makes us the trusted choice for homeowners looking to enhance their living spaces. Let us help you navigate the complexities of electrical upgrades with ease and confidence.
We repair, replace, and upgrade electrical panels across Spokane and North Idaho. That includes installing smart panels, adding capacity for new appliances, and making sure your system meets current safety codes. If you’re unsure what your panel needs, we can inspect it and walk you through the best options for your home.
A sub panel is a smaller electrical panel that distributes power to a specific area, like a garage, shop, or addition. If your home has extra living space or a detached structure, there’s a good chance you have—or need—a sub panel. We can help identify what you have and make sure it’s wired safely.
The meter measures how much electricity your home uses. The mast is the pipe that brings power from the utility line to your meter and into your panel. If either is damaged—say, after a storm—it’s your responsibility to get it repaired. Mainstream handles meter base and mast repairs and works directly with local utilities to keep everything safe and up to code.
We start by inspecting your current panel and circuits, then determine what needs to change based on your home’s size, usage, and safety needs. For upgrades, we’ll replace the panel, reroute wiring if needed, and make sure everything is grounded, labeled, and code-compliant. You’ll get clear pricing and communication every step of the way.
Smart panels give you more visibility and control over your home’s power use. You can track usage by circuit, get alerts if something goes wrong, and even control breakers remotely. It’s a smart upgrade if you want better safety, efficiency, and future-ready features—all of which Mainstream installs and supports.
When everything’s working, your electrical panel is invisible. It hums along quietly behind a door in your garage, basement, or utility closet. But when something’s wrong—like a tripped breaker, flickering lights, or a dead outlet—you’re reminded that this unassuming box is the nerve center of your entire home.
At Mainstream Electric, Heating, Cooling & Plumbing, we know Spokane homes. Since 2000, we’ve been repairing, upgrading, and replacing electrical panels across the Inland Northwest—making sure families like yours stay safe, powered up, and prepared for whatever life plugs in next.
Think of your panel like a traffic cop for electricity. It takes the power coming in from the utility company and directs it safely to every room, appliance, and outlet. Each “circuit” is protected by a breaker, which shuts off power if it senses a problem—like a short or overload.
That moment your microwave shuts off when the toaster is running? Your panel just stepped in to protect the wiring. When the lights flicker as your air conditioner kicks on? That’s a sign your circuits are near their capacity. Want to install a hot tub, EV charger, or just add another freezer? You’ll need your panel’s okay—and its capacity to handle more load.
Some Spokane homes were built with 100-amp panels decades ago—great for the 1970s, not so great for 2025. Today’s homes are loaded with high-demand appliances, smart home tech, and sensitive electronics that need more protection and capacity.
Signs you may need a panel upgrade or replacement:
Mainstream installs new 200-amp panels that meet modern codes, protect your home, and prep your system for future upgrades. We also offer smart electrical panels that let you monitor usage from your phone and automatically shut off unsafe circuits.
If your home has a workshop, detached garage, or an addition, you might already have a sub panel—basically a secondary box that extends the capacity of your main panel. We can inspect, install, or upgrade these as well.
And if you’ve ever wondered how your utility knows how much power you’ve used, that’s thanks to your electrical meter. In most cases, the mast (or service entrance) and meter base are homeowner responsibility—not the utility’s. If they’re damaged in a storm or need repair during a panel upgrade, we handle that too.
We’ve been doing this for over 20 years. Our licensed electricians don’t just swap out boxes—they evaluate your entire electrical system for safety, efficiency, and room to grow. We walk you through your options, explain every step, and install clean, code-compliant panels that are built to last.
Don’t wait for a major failure to find out your panel can’t keep up. If you’re seeing signs of strain—or just want to plan ahead—Mainstream is your trusted local partner. We’ll help you understand what your home needs today and tomorrow.
Schedule your panel inspection, repair, or upgrade with the electricians Spokane trusts.
