Knob & Tube Wiring...Very SCARY Anytime of the Year!!!

This is a photo project on knob and tube wiring; a form of electricity delivery of days old. For some reason, I have seen more knob and tube wiring this year than in any other of the past 18 years… combined.

To stress to you the danger of knob and tube I have purposely given this project… shall we say… a seasonal theme. Hope you like it.

Here is a photo of some of the ceramics that I found in my Victorian (c.1891) in Oak Park before I removed them for the following photo.

This wiring is located in my basement. They were attached to one of the main support beams. Notice how the traditional knobs (round) were not used in this location. These square shaped wire holders were called “cleats” and to the left is a ceramic fuse box. From what I have read, this fuse box could possibly have been a neutral fuse; a fuse that, when it blew due to overload, still left a live hot wire somewhere in the system!

So what is Knob & Tube Wiring, anyway? Simply, knob and tube wiring is one of North America’s very first electrical systems for building structures. Most commonly used in these parts from about 1880 to the 1930’s, knob and tube (aka K&T) remained an inexpensive form of electrical wiring even as newer safer technologies developed. In the early 1900’s as electrical wiring techniques improved, K&T was half the cost of covered or protected (in pipe) wiring systems.

The above photo is alarming. This is what we discovered in the original plaster ceiling when we removed the false ceiling this year. The home’s original lighting was provided by gas fixtures. Brass gas pipes were throughout the home feeding various fixtures that burned for light. When electricity for homes came along (knob and tube), it was easiest to fish the wires along the same path as the gas piping. You need to be careful with these gas pipes if you find them in your walls for they could still be connected to the homes gas main.

The name, “Knob & Tube”, refers to the fact that the system utilized ceramic “knobs” (mostly round) to wrap coated wiring around and then run to another knob where the wire may have made a turn and then run to another… until it reached its destination of a light fixture or switch. The knobs have holes in the center. The knobs would be hammered with long nails into floor joists, building studs within walls before the plaster was installed, or on roof joists in attics. When you needed to get a wire through a piece of wood in the building’s structure then the electrician or home builder used ceramic “Tubes”. The craftsman would drill a hole in say a wall stud, place the ceramic tube in the hole and then run the coated wire through the tube on to its next destination. Basically, the ceramic tube is protecting the wood from being touched by an unprotected electrical wire.

I found these traditional knobs in my home’s attic. The attic kinda creeps me out, you know?… Like you are not really alone...? Anyway, what is even more interesting are the protruding wires. See them? This is most likely the central electrical feed. The main would have entered the house from outside up into the attic. Then the main was split off into several branch circuits and snaked throughout the home.

OK, Steve, what’s with the little scary characters. Those are actually finger puppets I got at Pumpkin Moon in Oak Park. These photos I use the puppets in are a “hat tip” to a very awesome photographer out of Italy, Luca Rossini.

 So why is (knob & tube) SCARY!?!?!?! Well, it is very scary to have this type of wiring still existing in a home as a source of electricity. Chuck Allen, a licensed home inspector for National Property Inspections, serving the Chicago area, tells me K&T wiring is dangerous for a number of reasons. “(Wire) insulation becomes brittle and falls off exposing energized wire. Energized circuits may prove hazardous to human health (electrocution) and in some cases poses a real fire hazard since the connections of wires is generally loose and can arc.” says Allen.


This type of ceramic K&T fixture is called a cleat. It is just another form of wire anchoring and feeding within a home. I found cleats used in my open unfinished basement area only.

Look at how long that nail is. And look closely at the nail head. That is a type of cloth padding used under the nail head so that it didn’t damage the ceramic.

Now, my own home had K&T wiring when we moved in the house in 2000. We immediately had a professional electrician (Ron LaRosa of R&L Maintenance - (708) 383-7110) come in and clean it all up.

This is a classic shot of the wires running through the ceramic tubes. The tubes protect the wire from rubbing up against the wood and possibly causing a fire.

But here is something Chuck told me I was never aware. This old form of transmission of electricity around the house relied on the air gaps in the walls where the wires ran to provide additional cooling for often overloaded circuits. As a real estate professional that is around old homes everyday this means you better make sure you have no live knob & tube when you go to blow in insulation in your old home’s walls!!!

OPRF - The Scoop on Schools

How do you compare the Oak Park and River Forest public school systems and some of the private programs within the surrounding communities? 

Remember, I attended some of these schools growing up in the OPRF area. I also have sent my own kids into these same local schools. From personal experience, I attended Pilgrim Nursery School, Beye School Kindergarten, St. Giles 1st-8th, and St. Ignatius College Prep for high school. My daughters and son have attended First United Church Nursery School (an awesome experience), Oak Park's Holmes Elementary, and now I have one at Gwendolyn Brooks Middle School, one at Oak Park & River Forest High School, and one off to college at Tulane!!!

Oak Park

Oak Park might not rank as high for their public school system as River Forest, but I feel Oak Park offers the most complete package to serve a family from play school, preschool, kindergarten, elementary, middle, and on to high school.

Several years ago, Oak Park completed a $60 million physical and curriculum upgrade of its schools. The public elementary and middle schools are divided into districts. This means where you live decides what schools you will attend and there are rarely any exceptions. Some of the schools score or rate better than others so obviously this translates into some districts being more desirable to live in than others. When I take you for your first tour of Oak Park and to look at some homes we can discuss this at length at that time. This district map will help you visualize the areas in Oak Park as they pertain to school districts.

My wife, Julie, and I have been very impressed with District 97. It is a fantastic school system. 

River Forest

The River Forest public school system is small and very successful in providing a top notch education and producing some impressive scores and ratings. At the time I am writing this - the River Forest public middle school (Roosevelt) ranks #3 in the state. River Forest (as well as Oak Park) also has a number of outstanding private schools like Montessori programs (Keystone, Alcuin, Intercultural). Keep in mind River Forest is a more expensive market to purchase in than Oak Park. Their excellent school system is one of the reasons why..

Elmwood Park

The Elmwood Park school system is nothing to overlook as it is currently ahead of state and national averages. The system consists of two elementary schools, one middle school and one high school. The website link below for Elmwood Park district 401 is very comprehensive!

Local Things To Do!

An Abundance of Activities In and Around the Oak Park & River Forest Area

Oak Park, River Forest, Forest Park, Elmwood Park...So Much To Offer!

There is plenty to do in the Chicagoland area and below I have included some links to our most popular attractions. Within the our local community, there is also an abundance of events and activities to do in and around the Oak Park/River Forest area.


That reason alone is why many people move here. In a matter of minutes, you can be in downtown Chicago but if you want a little quaint village evening with excellent dining, a movie, a walk through our historic districts… there is no place like Oak Park River Forest.


Below are my favorite local activities & seasonal highlights:
