Knob and tube wiring help for Des Moines homes

Many older homes in Des Moines were built before modern electrical demand. Over time, homeowners added appliances, outlets, remodel work, lighting, heating and cooling equipment, office setups, EV charging, and other loads that older wiring was never designed to support.

If your home still has active knob and tube wiring, Benchmark Home Services can inspect the system, explain what is still in use, identify safety concerns, and help you plan a practical replacement path. Some homes need targeted replacement. Others need broader rewiring to make the electrical system safer, grounded, and easier to use.

Our goal is simple: help you understand what is inside the walls, what needs attention first, and how to upgrade the home without creating unnecessary disruption.

Knob and tube wiring upgrades in Des Moines

Not all old wiring is obvious

Knob and tube may still be active in attics, walls, basements, crawlspaces, light fixtures, or older circuits that were never fully replaced.

Signs your Des Moines home may still have knob and tube wiring

Two-prong outlets Older ungrounded outlets can be a sign that parts of the home still rely on outdated wiring.

Cloth-covered wiring Visible older wiring in attics, basements, or crawlspaces should be inspected before remodel or insulation work.

Flickering or dimming lights Loose connections, aging wiring, overloaded circuits, or mixed electrical systems can cause inconsistent power.

Insurance or inspection flags Active knob and tube wiring may create problems during home sales, insurance reviews, or renovation planning.

If you see exposed old wiring, smell burning, notice heat near switches or fixtures, or suspect wiring is buried in insulation, stop disturbing the area and call a licensed electrician.

Knob and tube services available in Des Moines

Knob and tube inspection

We inspect visible wiring, check active circuits, review common problem areas, and help determine whether old wiring is still powering parts of the home.

Knob and tube removal

We remove or abandon outdated wiring safely where appropriate and replace old circuits with modern wiring designed for current electrical needs.

Modern wiring replacement

We upgrade old circuits with grounded wiring, safer device boxes, improved circuit layout, and code-conscious installation methods.

Old-house rewiring

Older homes often have layered electrical systems. We help untangle past modifications and create a safer, more usable wiring plan.

Panel and circuit planning

Knob and tube replacement may reveal the need for better circuit distribution, panel corrections, or additional capacity planning.

Remodel and insulation prep

Before remodels, attic insulation, or wall work, older wiring should be evaluated so unsafe conditions are not covered up.

Careful removal with less disruption

We plan access points, protect finished areas where possible, and focus on replacing old wiring safely and efficiently.

Why knob and tube replacement is different from ordinary wiring work

Knob and tube projects are different because the wiring is often hidden, modified, or mixed with newer electrical work. Some homes have partial replacements where newer outlets were added but older wiring still feeds lights, bedrooms, attic runs, or other areas.

That is why the first step is not guessing. It is inspection and planning. We look at how the home is actually wired, where access is available, what circuits are active, and what needs to be updated to make the system safer and more useful.

Identify active old wiring before deciding what needs replacement
Plan safer grounded circuits for modern devices and appliances
Reduce unnecessary wall damage with practical access planning
Coordinate related upgrades such as panels, outlets, lighting, and circuit layout

Our knob and tube replacement process

1. Inspect the wiring

We look for visible knob and tube, test affected areas, review likely circuit paths, and identify where old wiring may still be active.

2. Build a replacement plan

We explain the safest and most practical approach, including access points, circuit needs, panel considerations, and any related upgrades.

3. Replace and modernize

We remove or disconnect outdated wiring where appropriate and install modern wiring, devices, circuits, and protections for the home.

Updated wiring for safer, more usable older homes

Modern wiring replacement is about more than removing old materials. It gives your home a safer foundation for today’s electrical needs: grounded outlets, better circuit layout, improved lighting, safer device connections, and more dependable power for everyday use.

If your Des Moines home has older wiring, past remodels, ungrounded outlets, flickering lights, or an inspection report that mentions knob and tube, Benchmark can help you understand the next step.

Inspection services for knob and tube wiring

Benchmark Home Services can help you understand what is present, what is active, what is unsafe, and what your options are. We also help homeowners plan improvements in a sensible order, especially when old wiring overlaps with panel upgrades, lighting changes, or broader rewiring.

You can also learn more about the history of knob and tube wiring and why older systems often need careful evaluation before being reused, covered, or modified.

 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.

Frequently asked questions

Is knob and tube wiring unsafe?

It can be. Knob and tube wiring becomes more concerning when it is active, damaged, overloaded, modified, buried in insulation, or used with modern electrical demand. An inspection helps determine the condition and risk.

Do I need to replace all of it?

Not always, but active knob and tube usually deserves careful evaluation. The right scope depends on how much is still active, where it runs, what condition it is in, and what upgrades the home needs.

Can knob and tube affect insurance?

Yes. Some insurance companies may refuse coverage, increase requirements, or ask for replacement when active knob and tube wiring is present.

Can knob and tube be buried in insulation?

Knob and tube wiring was not designed to be covered by insulation. If you are planning attic insulation or find old wiring already buried, have it inspected before disturbing or covering it further.

How long does replacement take?

The timeline depends on home size, access, wall construction, attic or crawlspace conditions, and how much wiring needs replacement. We provide estimates based on the actual home.

Do you also handle related panel or circuit work?

Yes. Older wiring projects often connect to panel capacity, circuit layout, grounding, outlet placement, and lighting improvements. Benchmark can help plan the full electrical path.
