 Trustindex verifies that the original source of the review is Google. Called Benchmark with a problem where my power was flickering and going out. Ed called me same day and came to my house in Ballard in a few hours. Took him no time to diagnose, while explaining the problem to me in clear language. Super helpful, friendly service!

Owner's reply
Thanks, John! It was good meeting you, and I’m glad I could get out there quickly and help with the troubleshooting. I’m happy the explanation helped, too. I appreciate you calling me and taking the time to leave a review!

 Trustindex verifies that the original source of the review is Google. Edward from Benchmark was great from start to finish. He reached out promptly after my initial contact, was flexible about a reschedule and gave me a decent window re when he'd arrive, which he did.
He's pleasant, but also wants to give you information you can use to help yourself. He explained and checked many small things that had accumulated. Overall we couldn't get my issue to happen during his call to West Seattle (Just like going to the autoshop, the sound never happens then!) but he went over a number of possibilities and confirmed that it was unlikely to be major issues because of XYZ in the electrical box or in the switch/bulb. I was relieved, but he wasn't finished! He left and sent a detailed follow up email so we can pretty easily (probably) remedy the situation ourselves before calling him back.

However, if needed, I'd gladly seek Edwards assistance in the future. If you just want someone to fix your problem and you're willing to just pay for the time, I'm sure he's capable of doing that too. Thanks so much!

Owner's reply
Thanks, Nadine! It was great meeting you. And yes, those intermittent problems have a way of disappearing as soon as someone comes to look at them!

I’m glad we could go through your questions and give you a few things to try. Hopefully the follow-up email helps get it sorted, but if it keeps acting up, give me a call. I’m happy to make another trip to West Seattle.

I really appreciate the thoughtful review!

 Trustindex verifies that the original source of the review is Google. I called Ed, the electrician to come and fix some wiring issues, outlets, and had him look over my electrical panel, among other things. Ed was prompt in responding, fitting me in after his work hours as he knew my urgency with the listing was looming.

He was super easy to work with, humous and professional at the same time. Ed gave me some perspective advice on what a housing inspector might want to see. I  added a few more projects for him to fix now rather than later.

If you're looking for a down to earth guy who knows what he's doing, fair on work ethics and a person you can trust, Call ED!  Super happy with his knowledge, honesty and friendly manner. 😊

Owner's reply
Jane, thank you for such a thoughtful review! I’m glad I could fit you in and help get those electrical items taken care of before your listing. It was a pleasure working with you—and sharing a few laughs along the way! Your kind words about my honesty and workmanship mean a lot. Wishing you a smooth sale, and thank you for trusting Benchmark Home Services! —Ed

 Trustindex verifies that the original source of the review is Google. Our dryer kept flipping the breaker.  Ed came out quickly, diagnosed and fixed the problem, all while knowledgably explaining to us what was going on. I recommend calling Benchmark Home Services if you need assistance with your electrical panel.

Owner's reply
Thank you, Sonja! It was a pleasure helping you and Ryan. A dryer repeatedly tripping the breaker can signal a problem that shouldn’t be ignored, so I’m glad I could diagnose the cause, make the repair, and explain what was happening along the way. Thank you for trusting Benchmark Home Services and for taking the time to recommend us!

 Trustindex verifies that the original source of the review is Google. Ed came out to our home on a holiday and did a great job.  He explained everything that was going on with our electrical box and fixed the issue between our electrical and our dryer.  Great job! Will contact again and recommend to anyone who needs an electrician.

Owner's reply
Thank you, Ryan and Sonya! I was glad I could make it out and help, especially on a holiday. Electrical problems involving a dryer can be frustrating, so I’m happy we were able to track down the issue, explain what was happening at the panel, and get everything working properly. I truly appreciate your recommendation, and please don’t hesitate to call if you ever need help again.

 Trustindex verifies that the original source of the review is Google. Ed got back to me quickly and was on site within a day or two.  He quickly diagnosed the problems in three rooms and resolved it.  He discovered other issues that he can fix before they become bigger ones down the road.  Great service.

Owner's reply
Thank you, Len! I’m glad we could respond quickly, diagnose the electrical issues in all three rooms, and get everything working properly. I also appreciate the opportunity to identify those other concerns before they develop into larger problems. Thank you for choosing Benchmark Home Services!

 Trustindex verifies that the original source of the review is Google. I’ve always been the kind of person who tries to figure things out myself. When two basement lighting circuits stopped working in my older house, I spent hours checking breakers, switches, wiring, and tracing the problem with a multimeter. The strange part was that the outlets still worked, which sent me down more than a few dead ends and had me questioning my own diagnosis.

Eventually, I called Benchmark.

What stood out right away was their methodical approach. Rather than guessing or replacing parts unnecessarily, they took the time to listen to what I had already investigated, ran their own tests, and systematically worked through the possibilities. Their experience was obvious from the start.

The issue turned out to be a detached neutral in the attic wiring, something I likely never would have discovered on my own. What had become a frustrating and confusing problem for me was diagnosed quickly and repaired correctly.

Just as important, they explained both the cause and the solution in clear, straightforward terms. It’s reassuring to know there are still professionals who combine technical expertise with honest, thoughtful service.

The next time I need electrical work, I know who I’m calling.

Owner's reply
Shane, thank you so much for taking the time to leave this review here as well. We really appreciate the detailed feedback and the opportunity to help with the lighting circuits in your Burien home.

Older-home electrical troubleshooting can be tricky, especially when part of the system is still working and the usual checks do not point directly to the issue. We’re glad our team was able to take a methodical approach, listen to the troubleshooting you had already done, locate the detached neutral in the attic wiring, and get everything repaired properly.

We appreciate your kind words about our communication, honesty, and service. Thank you again for trusting Benchmark Home Services — we’ll be happy to help whenever you need electrical work in the future.

Knob and tube wiring replacement for older Normandy Park homes

Knob and tube wiring was common in older homes, but it was not designed for the way modern households use electricity. Today’s homes often depend on computers, kitchen appliances, entertainment systems, heat pumps, chargers, lighting upgrades, and more circuits than older wiring was built to support.

Benchmark Home Services helps Normandy Park homeowners understand what is still in place, whether the wiring has been modified, and what needs to be updated. The right plan may include replacing knob and tube wiring, adding grounded circuits, updating outlets, improving panel capacity, or planning a larger rewiring project.

We focus on clean, practical recommendations that improve safety without guessing. Older homes can have layers of past electrical work, so a careful inspection matters before deciding what should be replaced first.

Knob and tube wiring should be evaluated carefully before remodeling, adding insulation, adding heavy electrical loads, or installing new equipment. Old wiring, ungrounded circuits, and hidden splices can create safety and insurance concerns.

Knob and tube wiring upgrades in Normandy Park

Older wiring needs a practical plan

The goal is not just to remove old wiring. It is to give the home safer, more useful circuits for how the space is used today.

Knob and Tube Electrical Services

Older wiring projects often connect to panel capacity, grounding, outlets, lighting, remodel work, and whole-home rewiring. We help identify the right next step.

Knob and tube inspections

We inspect accessible wiring, affected circuits, devices, panel conditions, and visible signs of unsafe modifications or aging electrical work.

Knob and tube replacement

We replace outdated wiring with modern wiring methods that better support grounded outlets, safer circuits, and current household power needs.

Grounded circuit upgrades

Ungrounded circuits can limit safe use of modern electronics and appliances. We can plan grounded circuit upgrades where they make sense.

Panel and breaker planning

Older wiring replacement often reveals panel limitations. We can evaluate whether the panel is ready for updated circuits and added loads.

Outlet and switch updates

Rewiring work is a good time to replace outdated outlets, improve device placement, and add safer power access where the home needs it.

Whole-home rewiring planning

If knob and tube wiring is widespread, a larger rewiring plan may be the best way to improve safety, usability, and long-term reliability.

Why knob and tube wiring is a concern

The main issue is not that the wiring is old by itself. The concern is what may have happened over decades of use: brittle insulation, ungrounded circuits, overloaded outlets, improper splices, hidden modifications, insulation around wiring, or added loads the original system was never meant to support.

A careful evaluation helps separate urgent safety concerns from planned upgrades. Some homes need targeted repairs. Others need broader rewiring, panel updates, or circuit redesign.

Look beyond the visible outlet

The wiring behind the walls, attic, crawlspace, panel, and junction points matters more than what is visible at a switch or receptacle.

Signs Your Older Wiring Should Be Checked

If your home has older wiring, these signs may point to overloaded circuits, ungrounded wiring, aging insulation, unsafe modifications, or panel limitations.

Two-prong outlets

Older two-prong outlets often indicate ungrounded wiring, which may not be ideal for modern electronics and appliances.

Frequent breaker or fuse issues

Repeated trips, blown fuses, or overloaded circuits can show that the home’s electrical system is struggling with current demand.

Warm outlets or switches

Heat around devices should be inspected. It can point to loose connections, overloaded wiring, damaged devices, or unsafe wiring conditions.

Flickering or dimming lights

Repeated flickering may be related to loose connections, overloaded circuits, fixture issues, or broader electrical system concerns.

Remodeling or insulation plans

Older wiring should be reviewed before opening walls, finishing spaces, adding insulation, or making changes that can hide existing wiring.

Mixed old and new wiring

Homes that have been partially updated may have a mix of old wiring, modern wiring, and past modifications that need a closer look.

A smarter approach to rewiring older homes

Replacing knob and tube wiring is not just about removing old cable. It is about designing a safer, more useful electrical system for the way your home is used now. That may include additional receptacles, dedicated appliance circuits, improved lighting circuits, GFCI protection, AFCI protection where required, panel upgrades, and better circuit organization.

Normandy Park homes can vary widely. Some have original wiring in isolated areas. Others have older wiring throughout the home. Benchmark can help identify the scope and explain your options in clear language.

Knob and Tube Wiring FAQs

Should knob and tube wiring be replaced?

In many older homes, replacement is recommended when the wiring is damaged, ungrounded, overloaded, improperly modified, surrounded by insulation, or no longer suitable for modern electrical use.

Is knob and tube wiring always unsafe?

Not every older wiring system has the same condition, but knob and tube wiring should be evaluated carefully. Age, modifications, insulation, load demand, and lack of grounding can create concerns.

Can you replace only part of the knob and tube wiring?

Sometimes. The scope depends on where the wiring is located, how it connects to the panel, what circuits are affected, and whether partial replacement would leave other concerns unresolved.

Will knob and tube replacement damage my walls?

Some access may be needed, but the plan depends on the home. We look for practical wiring routes and explain the expected impact before work begins.

Can I add insulation over knob and tube wiring?

Existing knob and tube wiring should be evaluated before insulation is added. Covering older wiring can create heat and safety concerns, especially if the wiring is still active.

Can knob and tube wiring affect insurance?

It can. Some insurance companies have concerns about active knob and tube wiring. If insurance, sale, or remodeling issues come up, an electrical evaluation can help clarify what needs to be updated.

Does knob and tube replacement require a panel upgrade?

Not always, but it is common to review the panel during older wiring projects. If the panel is outdated, crowded, damaged, or undersized, panel work may be recommended.

Are you licensed and insured?

Yes. Benchmark Home Services is licensed in Washington under WA #BENCHHS818NT and is insured.
