Where older conductors remain
We look at every room to see where this wiring is still active. We find the connections that need our attention.
What to know before you get started.
Many older homes in Moscow and Pullman, especially near the University of Idaho and College Hill, still have this original wiring. We look at your attic and walls to tell you what needs replacing.
Start with what you need
We start by looking at where your old wiring remains and what it serves. Your insurance carrier may ask about it when you buy or renew your policy. Some want it inspected or replaced, so please check with your agent.
Visible splices and device boxes
We look for open splices in your basement or attic. We tell you if we can fix the connection or if the circuit needs a full update.
Grounding needs
Your modern appliances need a ground. We look at your system to see how we can add that protection to your circuits.
What we look for in an older house
This wiring is often hidden behind plaster or in tight attic spaces. We use our experience to find the best route for your new wires.
Attic, basement, and wall access
We look at your home to see how we can reach your walls. We minimize the openings we make to keep your finish repairs small.
Loads served by each circuit
We check how much power your circuits draw. If they are overloaded, we add new circuits to your panel.
Finish repair assumptions
We tell you exactly what we expect to open. We make sure you know who handles the finish repair for your walls.
Compare a contained fix with a broader correction
We give you choices based on what we find. Sometimes a small repair is enough, and sometimes a larger update is the only safe way.
Contained work
We keep the work limited to the area we need to fix. We check the remaining wires and tell you what shape they are in.
Related correction
If we find that one circuit is tied to another, we tell you how to fix both so your home stays balanced.
Future phase
We help you plan your budget by telling you what you can do now and what you can phase for later.
Helpful details, when you have them

Record condition and alterations
We look for loose connections or added loads that could overheat. We tell you what we see.

If you are buying a home, we look at the wiring and tell you plainly what we see before you commit.
Questions about knob-and-tube wiring replacement
What should I send for a knob-and-tube evaluation?
A short description is enough to start. If you have them, your address, photos, and any access details are helpful.
Can I get a price from photos alone?
No. We need to see your home in person to find hidden damage and confirm your circuit layout.
What can change the estimate?
Access to your attic, the condition of your panel, and how much wall we need to open can change the final price.
Can you quote this from my home listing?
No. Listings do not show the real condition of your circuits. We must visit your home to give you an accurate price.
