 Trustindex verifies that the original source of the review is Google. First time using this company. The owner Rob and his employees were very fast, professional and helpful. I had scheduled morning of and they had an electrician out to my location within an hour. I then needed additional work done the next day and they were able to help immediately and were very easy to work with. I will definitely continue to use them in the future. 10/10 service and very friendly. They took the time to explain things to someone who knows nothing about electrical work, something most electricians will not do.

 Trustindex verifies that the original source of the review is Google. After finding a major issue with our electrical panel, Langstaff & Sloan diagnosed the problem for us and seamlessly guided us through an electrical upgrade and repair with minimal disruption in the dead of winter.

Rob, Phil, Arsh, and the crew were professional, responsive, and  have a commitment to high-quality work at a reasonable price. They'll work within your budget and won't ever be opportunistic and drive you towards the more expensive result, just the one that makes the most sense for you and your home. Very happy with the service, and can't recommend them enough for any residential work.

 Trustindex verifies that the original source of the review is Google. The crew was shockingly good, and living through a week long knob & tube upgrade with a newborn baby at home was a breeze, not the dreaded nightmare we had anticipated. The guys were very communicative and conscientious, minimally disruptive, efficient, and of course the quality of the work was top notch.
Thank you to Rob, Colin, and the rest of the guys.

 Trustindex verifies that the original source of the review is Google. I can’t thank Rob enough for his incredible support in diagnosing and solving an electrical issue in my kitchen. I had been struggling with a frustrating problem—every time I used my microwave, it would trip the breaker and shut off power to my fridge as well. I was genuinely concerned, especially living in a condo where access to wiring can be tricky.

Rob quickly and confidently identified the root cause of the issue: both the fridge and microwave were on the same circuit, overloading the breaker. Not only did he walk me through the technical side in a way that made perfect sense, but he also guided me step-by-step on how to test the outlets, identify the GFCI and breaker panel, and safely work around the issue until a long-term fix could be arranged.

What really stood out was his patience, professionalism, and ability to explain complex electrical details in a simple, reassuring way. Thanks to Rob, I now fully understand how to avoid overloading circuits, and I feel much safer in my home.

If you’re looking for someone who’s knowledgeable, reliable, and genuinely cares about solving your problem the right way — Rob is the one. Highly recommended!

 Trustindex verifies that the original source of the review is Google. Detailed and quality service. I required electrician due to cable length too short and not sufficient to replace led podlights. The lines are inspected in detail and reorganized to gain more clearance to cable length. Work is done neatly, tidy and professionally.

Frequently Asked Question

How long does knob and tube wiring last?

The common life expectancy of knob and tube wiring is 25 years, due to the rubberized cloth insulation used on the wires beginning to break down. While the wiring itself remains functional, the deterioration of insulation increases the risk of injury and damage that can cause more serious issues. As this type of wiring is an outdated option, dating back to the early to mid-1900s, the homes that still have it today are living on borrowed time.

How much current can knob and tube handle?

Knob and tube wiring can only exist in 15-amp ratings, which is a very low current on the general scale of wiring methods. Most modern devices require more power than 15-amps to function properly, which means that the devices may not work, or the wiring will be working much harder than it is designed to. Neither of these circumstances are ideal for your home, nor are they safe.

Is knob and tube wire safe?

There are several concerns surrounding knob and tube electrical, as it is outdated, which means its level of safety is questionable. The following are issues associated with this type of electrical wiring that homeowners should be aware of. As an ungrounded system, it increases the risk of injury; deterioration or cracking likely has happened over time, which can lead to an electrical fire; and newer wiring is often connected to knob and tube wiring, which creates dangerous conditions. Langstaff and Sloan Inc advises all homeowners to replace their knob and tube wiring. Having a licensed electrician upgrade your electrical will ensure your home is as safe as possible.

How do you know if a knob and tube is active?

While you can tell if a knob and tube wire is active by following the wires and seeing where they lead to, the safest way is to hire a professional. At Langstaff and Sloan, we send one of our licensed electricians to inspect your home’s wiring and see what condition it is in. Alternatively, if you have some technical knowledge of electricity, you may also use a voltage stick, otherwise known as a “tick buster.” By inserting the probes into the knob and tube fixture, you may test the alternating current. If the result is within 110 to 120 volts, the wire is live, so proceed with caution.

Is knob and tube a problem?

While many homes built between 1900 and 1945 have knob and tube wiring, there are several concerns associated with this wiring method that should not be ignored. It is an ungrounded system, which increases the likelihood of damage or injury. This is not only because it is old, meaning it may have deteriorated or cracked, but also because modern devices are not properly supported by it. If your home is suspected to have or has been confirmed to have knob and tube wiring, it is time to call Langstaff and Sloan Inc and book your wiring replacement.
