Western WA Old Wiring Specialists
When Your Wiring Has Outlived Its Safe Working Life
The Seattle and Tacoma corridors are home to a high concentration of properties built more than a century ago. Many of those buildings still carry knob-and-tube wiring, a system that was standard in its era but was never designed to support modern electrical loads. Over time, insulation degrades, connections loosen, and the risk of overheating grows. A complete home rewiring or targeted old wiring replacement is often the only reliable fix. CTR Electric's licensed team assesses each system honestly, explains what needs to be done, and coordinates the wall-access work so the project stays organized from start to finish. Our crews have handled these evaluations and replacements across the I-5 corridor for decades, and we know exactly what to look for in aging Western Washington construction.
What the Process Looks Like
Honest Expectations for a House Rewiring Project
A house rewiring project requires wall access. There is no way around it, and any contractor who tells you otherwise is not being straight with you. CTR Electric will walk you through exactly where access points are needed before any work begins, so there are no surprises once the job is underway. The electrical work itself, including removing old conductors, running new wiring, and verifying every connection, is handled entirely by our licensed electricians. Drywall patching and finish repairs after the job are the property owner's responsibility, and we will tell you that upfront. What you get from CTR is a fully replaced, code-compliant electrical system and a clear record of what was done. No guesswork, no shortcuts.
Commercial Rewiring in Western WA
Electrical System Upgrades for Commercial Properties
Rewiring is not limited to residential properties. Commercial spaces, particularly older retail, warehouse, and office buildings across the I-5 corridor, often carry wiring that cannot safely support current tenant loads or code requirements. CTR Electric handles commercial electrical system upgrade work with the same licensed crew and the same standard of precision we bring to every job. For larger-scale projects, we work with an Electrical Engineer for service sizing and load calculations, a resource most local contractors simply do not have. If your building is due for a rewiring evaluation, our team provides a thorough assessment and a clear scope of work before any commitment is made. For other upgrade needs, see our dedicated panel upgrade and service change page.

30 Years of Wiring Work, Zero Shortcuts
CTR Electric is a family-operated contractor that built its reputation entirely on repeat business and referrals, with zero advertising for the first 30 years.

Our team of four licensed electricians brings that same standard to every rewiring project, whether it is a single-room evaluation in Enumclaw or a full electrical system upgrade in a multi-unit building in Seattle or Tacoma. Integrity, precision, and reliability are not marketing phrases here. They are the reason clients keep calling us back.
Common Rewiring Questions
What Western WA Property Owners Ask About Rewiring
How do I know if my home still has knob-and-tube wiring that needs to be replaced?
Knob-and-tube wiring was commonly installed in homes built before the 1950s. Signs it may still be present include a very old electrical panel, cloth-wrapped wires visible in the attic or basement, and a history of tripped breakers or flickering lights under normal loads. The most reliable way to confirm it is through a professional evaluation. CTR Electric's licensed electricians inspect terminations, connections, and the overall condition of the system to give you an accurate picture of what is there and whether replacement is warranted.Will electricians have to cut into my walls during a rewiring project?
Yes, wall access is required for a complete rewiring. New wiring cannot be run through finished walls without opening them at key points. CTR Electric will walk through the property with you before work begins and identify exactly where access is needed, so there are no surprises during the job. The electrical work, including removing old conductors and installing new wiring, is handled entirely by our licensed crew. Patching and finishing the drywall after the electrical work is complete is the property owner's responsibility, and we are upfront about that from the start.Is knob-and-tube wiring automatically unsafe, or does the actual condition matter?
Condition matters, but age works against it. Knob-and-tube systems were not designed for modern electrical loads, and the insulation on older wiring becomes brittle and prone to cracking over time. Even systems that appear intact can have hidden degradation at connections or where insulation has been disturbed by past renovations. Many insurers also restrict or refuse coverage for homes with active knob-and-tube wiring. A professional evaluation by a licensed electrician is the only way to assess the actual risk level and determine whether targeted repairs or a full replacement is the right course.Does CTR Electric handle rewiring for commercial buildings as well as homes?
Yes. CTR Electric handles electrical system upgrade and rewiring work for commercial properties including retail spaces, offices, and warehouses across Western Washington. Older commercial buildings along the I-5 corridor frequently carry wiring that no longer meets current code or cannot support modern tenant loads. For larger commercial projects, CTR works with an Electrical Engineer for service sizing and load calculations, which allows for more accurate scoping on complex builds. The rewiring evaluation and replacement process for commercial properties follows the same licensed, code-compliant standard as residential work.How long does a complete home rewiring typically take?
Project duration depends on the size of the home, the complexity of the existing system, and how much wall access is required. A smaller single-story home may take a few days, while a larger or multi-story property with extensive knob-and-tube throughout can take longer. CTR Electric provides a clear scope of work before the project begins so you have a realistic timeline upfront. Scheduling flexibility is available for properties where minimizing disruption is a priority, and our team coordinates access points to keep the work as organized as possible.Will a rewiring project require a permit, and does CTR handle that process?
Most rewiring projects in Washington State require an electrical permit, and the work must be inspected by a local authority having jurisdiction. CTR Electric operates as a licensed electrical contractor, which means the work is performed to code and is eligible for proper permitting and inspection. Specific permitting requirements vary by county and municipality across the Western Washington service area, including King, Pierce, Skagit, and Snohomish counties. Your CTR electrician will address permit requirements as part of the project planning process so the work is fully documented and compliant.
