Electrical Installation Services for Spokane Valley Homes & Businesses

When it comes to keeping your home or business running safely and efficiently, your electrical system is the backbone. Whether you’re upgrading an older Spokane Valley home, adding new lighting, or preparing your commercial space for growth, professional installation makes all the difference. At Mainstream Electric, Heating, Cooling & Plumbing, we’ve been serving the Inland Northwest since 2000, starting as a trusted electrical company and growing into a full-service provider for plumbing, HVAC, and more. Today, our licensed electricians continue to deliver reliable electrical installation service across Spokane Valley, Spokane, and the surrounding communities.

Electrical work isn’t something to take lightly. Done right, it powers your home safely for decades. Done wrong, it can cause fires, outages, or costly damage. That’s why homeowners and business owners across the region trust Mainstream for installations that are safe, code-compliant, and built to last.

Electrician Experience You Can Rely On

For more than two decades, Mainstream has been part of the Spokane Valley community. We’ve seen the unique challenges of Inland Northwest homes and businesses first-hand — from older wiring in mid-century homes to growing neighborhoods where modern demands outpace outdated panels.

Our experience spans both residential and commercial electrical installation:

• Homeowners call us to bring power to remodels, add lighting, or upgrade panels.
• Businesses rely on us to design and install systems that can handle demanding equipment and daily use.

Because we’re a full-service company, our electricians often work side by side with our HVAC and plumbing teams. That means we see the big picture of your home’s comfort systems, ensuring your electrical work is integrated smoothly with everything else.

Common Electrical Installations We Handle

Electrical installation service covers much more than just wiring. At Mainstream, we’re called for projects of all sizes — from small upgrades to major overhauls. Some of the most common include:

Indoor & Outdoor Lighting

From recessed kitchen lights to motion-sensor security lighting, the right installation enhances both safety and comfort. Our electricians install lighting that’s functional, energy-efficient, and tailored to your space.

Landscape & Safety Lighting

Well-lit walkways, patios, and driveways not only look beautiful but also add security. We install durable outdoor fixtures that hold up against Spokane’s long winters and warm summers.

Remodels & Additions

If you’re finishing a basement, upgrading a kitchen, or adding a home office, new wiring is essential. We run power safely into new areas, making sure your circuits can handle the added load.

Panel Upgrades

Older homes weren’t built for today’s power-hungry appliances, hot tubs, or EV chargers. Mainstream upgrades panels to handle modern demand safely — giving you the capacity you need without tripping breakers.

Specialty Installations

Need power for a new shop, whole home generator, or backup battery system? We install a variety of systems that are customized to your unique needs.

Signs You Need a Trustworthy Electrician

Electrical problems rarely fix themselves — and waiting too long often makes things worse. Here are some signs it’s time to call Mainstream for electrical installation service:

• Flickering lights: If lights dim when appliances start, it could mean overloaded circuits.
• Breaker trips: Constantly resetting breakers signals that your panel isn’t keeping up.
• Outdated outlets or wiring: Two-prong outlets, discolored faceplates, or aluminum wiring are all red flags.
• Remodeling plans: Any new space needs proper electrical installation — DIY shortcuts are unsafe.
• Backup needs: In Spokane Valley, windstorms and winter outages happen. If you work from home, consider installing a generator or battery backup system.

These aren’t just inconveniences — they’re warnings. Calling a licensed electrician protects your home, your family, and your investment.

Why Professional Installation Matters

It’s tempting to think some electrical projects can be DIY’d. But improper wiring or poorly installed panels are among the leading causes of house fires. Even small mistakes can result in shocks, damaged appliances, or dangerous hazards hidden behind walls.

When you hire Mainstream, you get:

• Licensed expertise that ensures every project meets local codes.
• Safe, long-lasting results backed by years of training and experience.
• Peace of mind knowing your installation has been done right the first time.

With our team, you’re not just getting wires connected — you’re investing in safety and reliability for years to come.

Why Spokane Valley Homes Need Upgrades

Here’s the thing about homes in Spokane Valley: they weren’t all built with today’s electrical demands in mind. A lot of the mid-century houses still running on their original panels were designed for a couple of lights, a TV, and maybe one refrigerator. Fast forward to today — families are plugging in multiple computers, charging stations, air conditioning units, and sometimes even a hot tub out back. That old panel wasn’t built for this kind of load.

Even newer builds in the Valley can fall short. Many contractors install just enough to meet code, not necessarily what you’ll need long-term. So when you try to run a home office, kitchen appliances, and the AC all at once, breakers trip, lights flicker, or worse — wires overheat.

We’ve seen it all. From aluminum wiring in South Hill bungalows to undersized panels in Liberty Lake townhomes, the quirks of Inland Northwest houses are second nature to us. That’s why when we upgrade a system, we don’t just “swap out parts.” We make sure it’s designed for how your family actually lives today — and how you’ll grow into it tomorrow.

Installation You Can Rely On, Service You Can Trust

Every electrical installation we complete comes with our Home Comfort Guarantee. That means:

• Upfront pricing with no hidden fees.
• Licensed, background-checked electricians you can trust in your home or business.
• Repairs and installations done right — if there’s an issue, we’ll make it right.
• Complete satisfaction backed by our reputation across Spokane Valley.

We don’t just install electrical systems, we stand behind our work, giving you confidence long after the project is complete.
