Update Wiring Before Walls Go Back Up

Whole-home and partial rewiring services for homeowners in Johnston, Iowa.

If you live in an older Johnston home and plan to remodel, the wiring behind your walls may still use outdated materials that cannot safely support modern appliances, computers, or heating systems. Aluminum wiring, knob-and-tube systems, and undersized circuits were standard decades ago but no longer meet the electrical demands of a typical household. Jenson Electric, LLC replaces outdated wiring during renovations and coordinates with your contractor to keep the project on schedule while updating your electrical system to current code standards.

A rewiring project involves removing old wiring and running new copper conductors through walls, ceilings, and crawl spaces. The electrical panel is upgraded if necessary to handle additional circuits, and all connections are made inside properly rated junction boxes. The scope of work varies depending on whether you need a full-house rewire or targeted updates in specific rooms such as kitchens, bathrooms, or additions. Rewiring during a remodel gives you access to open walls, which reduces labor time and avoids cutting into finished surfaces later.

If you are planning a renovation in Johnston and want to confirm your wiring is safe and up to code, contact Jenson Electric, LLC to schedule a walkthrough.

How Rewiring Fits Into Your Remodel Timeline

When Jenson Electric, LLC works on a rewiring project in Johnston, the electrician coordinates with your general contractor to schedule rough-in work after framing is complete but before insulation and drywall go up. This phase includes running new wiring to outlets, switches, and fixtures, installing junction boxes, and connecting circuits to the panel. If your remodel includes adding square footage or reconfiguring rooms, new circuits are planned to match the updated layout and support the appliances or lighting you plan to install.

After the rewiring is finished, you will notice outlets and switches respond reliably without flickering or tripping breakers when multiple devices are in use. The updated wiring supports higher electrical loads, which means you can run a microwave, coffee maker, and toaster at the same time without overloading a circuit.

Once drywall is installed and painted, the electrician returns for trim-out work, which includes installing outlet and switch covers, connecting light fixtures, and testing every circuit to confirm proper operation. If your project involves moving a panel or adding a subpanel, that work is completed before rough-in begins to keep the schedule moving. Rewiring also improves resale value because updated electrical systems are frequently listed as a condition requirement by buyers and home inspectors.

What Homeowners Ask Before Starting the Work

Homeowners in Johnston typically want to know how rewiring affects their renovation timeline, what code changes apply, and whether partial rewiring is a practical option.

What are the signs that my home needs rewiring?
Frequent breaker trips, flickering lights, outlets that feel warm to the touch, or visible cloth insulation on wiring all indicate your home may need updated electrical work. Homes built before 1970 in Iowa often still contain original wiring that no longer meets current safety standards.
How does rewiring affect the renovation schedule?
Rewiring happens during the rough-in phase after framing and before drywall, so it does not delay the remodel if scheduled properly. Jenson Electric, LLC coordinates with your contractor to keep electrical work aligned with other trades.
Why is copper wiring preferred over aluminum?
Copper conducts electricity more efficiently and resists corrosion better than aluminum, which reduces the risk of overheating connections. Most modern electrical codes require copper wiring for branch circuits in residential applications.
What happens if I only rewire part of my home?
Partial rewiring focuses on specific rooms or circuits that need updating, such as kitchens or bathrooms where electrical demand is highest. The rest of your home remains on the existing system unless it shows signs of failure or you plan to remodel those areas later.
When do I need a panel upgrade during rewiring?
If your current panel cannot support the number of circuits required for your remodel, or if it is outdated and lacks space for additional breakers, an upgrade is necessary. Jenson Electric, LLC evaluates your panel during the initial walkthrough and recommends an upgrade if needed.
