Sub panel installation and repair in Lynnwood is a practical and cost-effective solution for homeowners who need to expand their electrical capacity without replacing their main panel. A sub panel, also called a secondary panel or distribution panel, is an additional breaker box that receives power from the main panel and distributes it to a specific area of the home or property. Whether you are finishing a basement, building an accessory dwelling unit, adding a detached garage, or expanding a home office, a properly installed sub panel gives you the circuits you need without overloading your existing system.
At In-House Electric, we provide licensed sub panel installation and repair in Lynnwood for homeowners throughout Alderwood Manor, Meadowdale, North Lynnwood, Pioneer Hill, Scriber Lake, and every neighborhood in the city. Since 2009, we have helped Lynnwood homeowners expand their electrical systems safely, correctly, and fully permitted, so every new circuit is ready for years of reliable use.
Lynnwood’s housing market has shifted significantly in recent years. Homeowners are finishing basements, converting garages, building ADUs, and upgrading home offices at a high rate, all of which require dedicated electrical circuits that existing panels often cannot accommodate. At the same time, many Lynnwood homes built between the 1950s and 1980s still operate on 100-amp main panels that have little or no room to add new circuits.
Rather than replacing the entire main panel, which is a larger, more costly project, a sub panel installation allows Lynnwood homeowners to extend their electrical capacity to a specific area efficiently. This is particularly common in Lynnwood neighborhoods like North Lynnwood and Alderwood Manor, where older homes are being expanded or updated to meet current living standards. Lynnwood’s damp Pacific Northwest climate also means that outdoor sub panels for detached garages and shops need to be properly weatherproofed and installed to Snohomish County code standards.
We install new sub panels in any location on your Lynnwood property, finished basements, detached garages, workshops, ADUs, and home additions. Our installation process includes proper sizing for your specific load requirements, correct feeder wire sizing from the main panel, and full weatherproofing for outdoor applications. Every installation is permitted and inspected through Snohomish County PDS.
If your existing sub panel is undersized for your current needs, a common situation as Lynnwood homeowners add EV chargers, workshop equipment, and home office loads, we upgrade the sub panel to a larger amperage unit that handles your full load safely. We assess your current and future requirements before recommending the right upgrade.
Detached structures on Lynnwood properties require their own sub panel to distribute power safely. We install and wire sub panels for detached garages, workshops, she-sheds, and accessory dwelling units, including proper grounding, weatherproof enclosures, and correct feeder sizing from the main panel. These installations are fully permitted and inspected.
Existing sub panels develop problems over time, from failing breakers and loose connections to moisture intrusion and corrosion. Our licensed electricians diagnose sub panel issues thoroughly and perform targeted repairs that restore safe, reliable operation. We replace failed breakers, repair feeders, correct grounding issues, and address any code deficiencies identified during inspection.
Sub panels with documented safety defects, including Federal Pacific Stab-Lok and Zinsco panels, require replacement. We remove and replace defective sub panels with modern, code-compliant units from trusted manufacturers, ensuring every circuit they feed is properly protected.
Proper sub panel installation starts with accurate load calculation. We assess your Lynnwood home’s existing electrical load, the demands of the new area being served, and the capacity of your main panel to determine the correct sub panel amperage, feeder wire size, and breaker configuration for your specific situation.
Sub panel installation in Lynnwood always requires a permit. We handle the full application and inspection process through Snohomish County PDS. Every installation is performed by a licensed electrician registered with Washington Labor and Industries under RCW 19.28.
Undersized sub panels are a common and costly mistake. We perform accurate load calculations before every installation to ensure your sub panel is correctly sized for both current and anticipated future demands, preventing overloading, repeated breaker trips, and premature failure.
We assess your actual situation and recommend the right solution, whether that is a new sub panel, an upgrade to your existing sub panel, or a repair. We never recommend more work than is genuinely needed.
Our quotes are fixed-price. What we quote is what you pay, even if the job takes longer than anticipated. No hourly surprises.

A sub panel is a secondary breaker box that receives power from your main panel and distributes it to a specific area of your home or property. You likely need one if your main panel is full, you are finishing a basement or garage, building an ADU, or adding a high-demand appliance in a remote area of your Lynnwood property.
Sub panel installation in Lynnwood typically ranges from $1,000 to $2,500 depending on the panel size, location, feeder wire length, and any required trenching for outdoor runs. We provide a transparent, fixed-price quote after a free on-site assessment.
