"His name is Andrew Johnson. He is going to be doing our carport next. He does all of our electrical but he also does incredible solar. It was around $17,000 for the solar. We have a big house. You can't beat his prices. He doesn't have a huge company. His guys are great. He shows up when he says. He does meticulous work. The city's came out and told him right in front us that he did better than perfect. He lives in our neighborhood. He told him to get on Angie's List"

"I'm very happy with the work that was done by Landmark construction and energy crew. At first, we met with Ron that came over and met with us about the issues that we had with our water heater and with the bills that we currently pay for electric. Ron recommended us to replace the bulky old water heater and to install a tankless system that will supply hot water immediately and with the use of less gas. We liked that idea and we decided to go for this project. Ron came over to our house with his 2 people that basically took care of all the removal and the installation of the new system. The work that they did took only 2 days from start to finish and now we have more space at the garage, and the bills are much lower than before…."

"Great. Joe Zimmerman of AAA Computers showed up on time, knew exactly what he was doing, and even supplied a power cord which was missing from the box the movers had packed the computers in. He went out of his way to make sure things were working correctly and gave me a tutorial on fixing issues by myself were additional problems to crop up."

"I had a great experience with a solar install from NRG Clean Power. I am an electrical engineer so I'm a huge nerd when it comes to the type of technology that I was looking for in a solar install. These guys use all enphase microinverters and solarworld panels, which is exactly what I wanted. My system has 16 280W panels, and it is working wonderfully. Once I said go, these guys were all over it. Sean Malloy was my sales guy, and he got the paperwork pushed through, and the permitting done in no time. The install contractors were all professional, and the job was done well. They also installed an upgraded main panel and installed a car charging station for my EV. I went from paperwork to system installed and operating in around 3 weeks. I would highly recommend these guys."

"The plumbing upgrade and dishwasher installation went very well this morning.  I bought a dishwasher for first-time installation in my older home and had texted Joshua the night before with pics of the "then current" plumbing and electrical situation.  He arrived on time with proper plumbing and electrical fittings and went immediately to work.  The used dishwasher I'd bought required more pieces, so getting those from Lowe's was arranged and he finished the entire job within 2 hours!  The only small concern (which he immediately straightened out!!) was the chrome airgap pop-up on the sink was a bit crooked, but again, he fixed that right up.   I am looking forward to hearing his estimate on some upcoming electrical  work for my patio.   I WILL recommend him to my neighbors and local friends!!

"The young guy who did the work was prompt and professional, but not well trained. He power washed my patio BEFORE blowing the leaves and sticks off my roof, so all the debris landed on my just cleaned patio, and he didn't follow up to clean it off.
He forgot to do the garage door and was all packed up when he asked me to inspect, so I just let it ride.

Electrical questions, answered by experts

Knob and tube wiring is old, and its casing is brittle. This means that it's possible to receive a dangerous electrical shock if you touch a live wire and essentially become an electrical pathway. Although the scenario is unlikely, touching any K&T wiring is simply not a good idea in any instance. Leave any wire handling to the professionals.

The average lifespan of a home electrical system is anywhere from 30 to 70 years or more, depending on the type of system you have. Modern electrical wiring, like aluminum or copper, can last 50 to 70 years while older types may need to be replaced sooner. Additionally, circuit breakers tend to last anywhere from 30 to 40 years, while electrical outlets need to be replaced every 10 to 25 years. 

It can be safe to buy or live in a house with knob and tube (K&T) wiring, but only if the system is in good condition, functional, and has been thoroughly inspected and approved by a licensed electrician. Never purchase a home with K&T wiring without getting a professional electrical inspection first.

Key considerations include:

  • Safety and Condition: An inspector will verify that the wiring is safe and has not deteriorated. Over time, the insulation can wear away, leaving exposed wires that pose a significant fire or shock hazard.

  • System Capacity: The electrical service should be at least 60 amps. However, even at this capacity, K&T systems often struggle to handle the demands of modern appliances and electronics.

  • Lack of Grounding: Knob and tube wiring is an ungrounded system, which is a safety concern for many modern devices.

  • Ongoing Maintenance: If you live in a home with K&T wiring, it's recommended to have it inspected by an electrician every one to two years to ensure it remains in safe working order.

Ultimately, any inspection or modification of a knob and tube system should always be performed by a certified professional.

A wire stripping tool is the easiest way to strip sheathing or plastic insulation from electrical wires. A self-adjusting wire stripper cuts and removes the sheathing without damaging the core wire.

Typically, when a 3-way switch only works when one switch is on, this is one of the most telltale indicators that the switch has gone bad (although this could also be the result of faulty or loose wiring). To diagnose the issue, toggle each switch until the light comes on. Once it’s on, toggle each switch separately again; the switch that doesn’t turn the light off is the bad switch.
