Redmond's tree-heavy neighborhoods, from Education Hill to Redmond Ridge, sit under thick canopies of Douglas fir and big leaf maple that shed limbs during fall and winter windstorms, the leading cause of PSE outages in this area. Add in the region's near-constant rain and humidity, which speeds up corrosion on unprotected wiring and enclosures, and a generator here needs weatherproofing that a dry-climate installation wouldn't require.
Local knowledge
What's different about generator installation in Redmond
We run service calls in Redmond every week — the same patterns come up again and again.
Redmond's mature tree cover along streets like Avondale Rd and in Grass Lawn means limb strikes on power lines are a routine cause of outages, not a rare event, so standby coverage pays off more often than in newer, tree-thinned subdivisions.
Many Redmond homes near Microsoft's campus and in Bear Creek run home offices with servers, multiple monitors, and networking gear that need clean, uninterrupted power, which pushes sizing decisions toward larger kW generators than a typical fridge-and-lights setup.
PSE service to Redmond runs both overhead and underground lines depending on the subdivision; underground service in newer developments like Redmond Ridge still loses power during substation issues, so proximity to buried lines doesn't rule out the need for backup.

How a Redmond generator installation visit works
1
Site visit and load assessment
We walk the property, check your electrical panel, and calculate what circuits or the whole home you want covered, factoring in Redmond's wetter-than-average rainfall for pad and enclosure placement.
2
Generator sizing and quote
Based on your square footage and must-run appliances, we recommend a generator size and give you a written quote within the $4,500-$12,000 range before any work starts.
3
Permitting
We pull the required electrical and, if needed, gas permits through the City of Redmond or King County, so the install is inspected and code-compliant.
4
Installation and transfer switch setup
Our electricians set the generator on a level, moisture-resistant pad, wire the automatic transfer switch, and connect fuel or gas lines, typically completing the work in one to two days.
5
Testing and walkthrough
We run a full load test, confirm the automatic transfer switch kicks in correctly during a simulated outage, and walk you through startup, weekly self-tests, and maintenance intervals suited to our damp climate.

Straight answers
Generator Installation in Redmond — FAQ
How often does Redmond actually lose power?
Redmond doesn't see outages daily, but wind and rain events between October and March regularly knock out power in tree-lined areas like Education Hill and parts of Bear Creek. PSE crews often need hours to reach downed lines in wooded sections, which is why many homeowners here install standby power rather than relying on portable units.
Do I need a permit to install a generator in Redmond?
Yes. Standby generator installations require an electrical permit, and if you're running a gas line, a separate mechanical or gas permit through King County or the City of Redmond depending on your address. We handle both as part of the installation.
Will Redmond's rain and humidity damage my generator?
Not if it's installed correctly. We set every unit on a raised, moisture-resistant pad and use weatherproof enclosures rated for the Pacific Northwest's wet season. Skipping this step is the most common reason we see corrosion or moisture damage on generators installed by out-of-area companies unfamiliar with local conditions.
How big of a generator do I need for a typical Redmond home?
Most single-family homes in Redmond land in the 14kW-22kW range for whole-home backup, though smaller 7kW-10kW units work for essential circuits only. Newer, larger homes in Redmond Ridge or Trilogy often need higher capacity due to bigger HVAC systems and electric appliance loads.
