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.
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.

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We remove or abandon outdated wiring safely where appropriate and replace old circuits with modern wiring designed for current electrical needs.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
Not every older home needs the same scope of work. Some need a focused inspection before a sale, insurance review, or remodel. Others need a full replacement plan because active knob and tube is still serving major parts of the home.
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.

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.
