Safer, Up-to-Code Wiring for Older Mount Vernon Homes
Older homes are part of what makes Mount Vernon and the rest of Skagit County special, but the wiring behind their walls wasn’t built for today’s electrical loads. CPI Plumbing, Heating, Cooling & Electrical rewires homes in Mount Vernon, Bellingham, and Oak Harbor, from a few problem circuits to the whole house.
Our licensed electricians inspect your wiring, explain what they find in plain language, and give you a written quote before any work starts. We charge by the job, not by the hour, and every installation is backed by our one-year warranty. It’s one part of our full range of electrical services.
Signs Your Home Needs Rewiring
- Knob-and-Tube or Cloth-Covered Wiring
Many older homes still have knob-and-tube or cloth-insulated wiring. It has no ground wire, and its insulation can crack with age.
- Aluminum Branch Wiring
Aluminum wiring used in some homes from the 1960s and 70s can loosen at connections and overheat. It needs to be repaired correctly or replaced.
- Two-Prong Outlets Throughout the House
Ungrounded outlets can’t safely power many of today’s electronics and appliances, and they don’t offer the protection of a grounded circuit.
- Scorched Outlets or Burning Smells
Discoloration around outlets and switches, or a hot plastic smell, means wiring is overheating. Call us right away.
- Constant Breaker Trips or Flickering Lights
When circuits stay overloaded, or connections keep failing, spot repairs only go so far.
- Damage From Rodents, Moisture or Past DIY Work
Chewed wires in the attic, corrosion in a damp crawl space, or splices made without junction boxes are common in older Skagit Valley homes.
Our Rewiring Services
Whole-home rewiring replaces old wiring throughout the house with new grounded circuits, outlets and switches. We work room by room, routing new wire through attics, crawl spaces and existing paths so openings in your walls stay small, and you keep power in most of the house while we work.
Not every home needs a full rewire. If the problem is limited to a kitchen, an addition or a few circuits, we rewire just those areas. We also add grounding to two-prong outlets and install the GFCI and AFCI protection code now requires in kitchens, bathrooms, garages, laundry rooms and outdoor areas.
If you’re planning a remodel or addition, that’s the best time to bring wiring up to code. With the walls already open, rewiring takes less time and less patching, and we can work from your plans so the electrical is done right the first time.
Rewiring and Your Electrical Panel
New wiring often goes hand in hand with a new panel, especially in homes with fuses or older breaker boxes. If your panel is undersized or outdated, we’ll quote electrical panel upgrades together with the rewiring so you see the full picture.
Wiring for Heat Pumps, EV Chargers, and New Appliances
Many rewiring projects start with a new appliance. A heat pump, an induction range or a Level 2 EV charger each needs its own properly sized 240-volt circuit, and older wiring can’t safely share that load. When we rewire, we plan those dedicated circuits at the same time, so you’re ready for the next upgrade without opening walls twice.
