Homes in Johnston ask more of their wiring than they did a generation ago. A house that was built with two or three circuits in the kitchen now runs a refrigerator, a dishwasher, a microwave, an air fryer, and a coffee maker, and that is before anyone mentions the home office down the hall or the EV charger in the garage. When the electrical system was not designed for that load, the symptoms show up as tripping breakers, lights that dim when an appliance kicks on, and outlets that simply cannot keep up. Summit Electric handles that kind of work across Johnston, from the quick fix to the full panel replacement.
The housing stock here covers a real range, from older homes with wiring that has never been touched to newer construction that is already pushing its panel capacity with modern appliances and equipment. Property owners, business operators, and landlords keeping rental units up to code all call us for the same reason: the electrical side of the building needs attention, and they want it handled correctly. Work is performed by licensed electricians who explain what they find before they start, and who treat the property the way they would their own.
The rate for any job depends on what the job actually involves. A straightforward outlet replacement and a panel upgrade are not priced the same way, and neither should be. When you call, we go over the work with you and give you the price before anything is scheduled. You know what it covers and what it costs before a licensed electrician comes out.
A few things can change a quote: whether the existing wiring needs to be extended or replaced, whether the panel has capacity for the new circuit, and whether the job requires a permit. Permit requirements vary depending on the type of work and where the property sits, and we confirm what applies to your address before anything starts. No-pressure estimates, priced up front, so you are not committing to anything before you know what you are agreeing to.
To get a price for work at your Johnston property, call (515) 395-4989 during our hours of 9:00 AM to 9:00 PM, every day.
A socket that has never worked, a switch that sparks when you flip it, an outdoor light that has been out for two seasons because replacing it keeps getting pushed to next weekend. These are the jobs that feel small enough to leave alone, and they are also the jobs where waiting tends to make things worse.
An outlet that has never worked may be on a circuit with a tripped GFCI somewhere else in the house, or it may have a loose connection behind the plate that is generating heat every time something is plugged in. A sparking switch is telling you something about the wiring behind it. An exterior fixture left unrepaired can let moisture into the box and create a fault that affects more than just the light. Don't let a small wiring issue turn into a fire risk, because the cost of a call is a fraction of what it costs to address the problem after it has spread.
We handle these calls every day. One call, and an electrician is on the way.
Most of the practical detail is on the electrical work rundown.
Electrical work in a city like Johnston does not look the same from one job to the next. A home built in the 1960s calls for different work than a house finished five years ago, and a commercial space has different demands than either. The full breakdown of what we do is on the service page, but the situations that generate most of our calls fall into a few clear categories.
Tripping breakers, dead outlets, flickering lights, and circuits that fail under load all point to something specific. We trace the problem to its source rather than replacing parts until something works. That means checking the panel, the circuit, the outlet or fixture, and the wiring in between. Arc-fault and ground-fault conditions both show up this way, and identifying which one is causing the problem determines the fix. AFCI and GFCI protection are often part of the solution, especially in older homes where those devices were never installed.
A panel that was sized for a different era of home electricity use eventually runs out of room. Adding a dedicated circuit for a new appliance, installing an EV charger, or finishing a basement all require capacity that an older 100-amp service may not have. We do load calculations as part of scoping panel work so the new service is sized for what the home actually needs, not just what it needs today. Grounding and bonding are checked and corrected as part of any panel replacement.
New outlets, ceiling fan installation, dedicated appliance circuits, lighting upgrades, and exterior weatherproof outlets are all jobs that start with a clear scope and a confirmed price. Circuit installation for a dryer, a range, or a workshop is straightforward work when the panel has capacity. When it does not, we talk through the options before anything is scheduled. The service page carries the full breakdown of what we install and how each type of job is handled.
A panel-mounted surge protector covers every circuit in the building with a single device. That is a different level of protection than a power strip, which only covers what is plugged directly into it. In a region where severe thunderstorms and lightning are a regular part of the calendar, whole-home surge protection is one of the more practical upgrades a property owner can make. It is also a job that can be done in a single visit, often alongside other panel work.
Older homes in Johnston sometimes still have knob-and-tube wiring, which was standard construction for decades but lacks a ground wire and was not designed for modern electrical loads. Insulation added around it over the years can trap heat in ways the original installation never anticipated. We assess what is present, explain what it means for the home, and walk through the options for remediation. Rewiring a home with knob-and-tube is a larger project, and we scope it carefully so you know what is involved before work begins.
A standard outlet replacement is a quick job. Upgrading to GFCI protection in a kitchen, bathroom, garage, or outdoor location is a code requirement in most installations and a genuine safety improvement in any of them. AFCI outlets and breakers are required in living spaces and bedrooms under current code, and older homes often lack them entirely. Tamper-resistant receptacles, USB combination outlets, and dimmer switches are all installations we handle in a single visit.
A three-way switch controls a single fixture from two locations, which is standard in stairwells and long hallways. When one switch in a three-way pair fails, the fixture may work from one end and not the other, or stop working entirely. Diagnosing a three-way switch problem requires tracing the traveler wires through both switches, which is not the same job as replacing a standard single-pole switch. We handle multi-location switching correctly, including smart-switch installations where the wiring needs to support the new device.
Commercial and light-industrial work in Johnston involves a different kind of planning than residential jobs. A retail space or office that has to stay open cannot have the whole building taken offline for a morning. We plan commercial electrical work around the operating schedule of the business, keeping the parts of the site that need to stay live exactly that way while the work happens elsewhere in the building.
Out-of-hours availability matters here. A business that closes at 6:00 PM may need electrical work done in the evening to avoid disrupting customers or staff during the day. We are open until 9:00 PM every day, which gives commercial customers a window that residential jobs rarely need. Good electrical work isn't complicated, it's just done right, and on a commercial site that means doing it at the right time as much as the right way.
Same-day service is often available for repairs and installations that cannot wait. When you call during our hours of 9:00 AM to 9:00 PM, we go over the job with you, confirm the price, and schedule the visit. For situations involving sparking, burning smells, or a partial power loss that is affecting multiple areas of the building, calling as early in the day as possible gives us the best chance of getting someone out the same day.
We work around tenants and businesses that need to stay open. If you cannot be at the property during the visit, call and we will talk through the access situation in advance. For rental properties, we coordinate with whoever is on-site so the job moves forward without the landlord needing to be present for every step. With a local company, your questions go straight to the people doing the work. Call in the morning. Powered by afternoon. Follow-up when you need it.
Johnston is our primary area in this part of Polk County, and we take calls from customers across the surrounding communities as well. If you are in Grimes, Urbandale, Saylorville, Windsor Heights, or Polk City, we cover you too. The same licensed electricians, the same pricing process, and the same availability apply across the whole area.
If you are not sure whether your address falls within our coverage, call and ask. We confirm coverage on the call and get you scheduled if we can reach you.
A sudden voltage dip when a refrigerator compressor, air conditioner, or well pump starts up usually means the circuit or panel is working close to its capacity. The motor draws a surge of current at startup that briefly pulls voltage down across the whole panel. We can assess whether the appliance needs its own dedicated circuit or whether the panel itself needs more capacity to handle the load cleanly.
Yes. We serve Grimes, Urbandale, Saylorville, Windsor Heights, Polk City, and the surrounding communities in Polk County, and the same process applies wherever you are. Call (515) 395-4989, go over the job on the phone, get the price, and schedule the visit. If you are not sure whether your address is covered, call and ask.
A dryer requires a dedicated 240-volt circuit, a specific outlet type, and a breaker sized for the load, none of which a standard 120-volt outlet circuit provides. Running a dryer on an undersized circuit or a shared circuit is both a code issue and a fire risk. We install dedicated dryer circuits and the correct outlet as a standalone job or as part of a larger project.
Yes, in most cases. A full rewire is only necessary when the existing wiring is genuinely unsafe or incapable of supporting the work being added. Many older homes just need targeted repairs, circuit additions, or panel upgrades rather than starting over. We assess what is actually there and recommend only what the situation calls for.
Some older breaker brands have documented histories of failure or are no longer manufactured, which means replacement parts may not be available and the breakers themselves may not perform reliably. We assess what is in the panel and explain whether the breakers are a concern. In many cases, the practical solution is a panel replacement rather than trying to source discontinued components.
Most welders and compressors draw more current than a standard 15- or 20-amp circuit can safely supply. Running heavy equipment on an undersized circuit causes nuisance tripping at best and overheating at worst. We install dedicated circuits sized for the actual draw of the equipment, including 240-volt circuits where the equipment requires it.
Homes with aging wiring tend to generate calls about outlets that have stopped working, circuits that trip under loads they used to handle, and light fixtures that flicker without an obvious cause. In some cases the wiring itself is the issue, and in others it is a panel that was never sized for the loads the home is running today. We trace the problem to its source on every visit and explain what we found before any work begins.
We can assess wiring that was done without a permit and tell you what condition it is in and what it would take to bring it up to current standards. Whether that work can be signed off as-is or needs to be redone depends on what is actually there. We explain what we find and what the options are before any remediation work is scheduled.
If we trace a problem and find that the fault is upstream of the meter, we tell you clearly and explain what the next step is. That typically means contacting your utility provider directly, since the service entrance and everything before the meter is their responsibility. We can describe what we found in terms that make it easier to report the issue to them accurately.
Yes. If you want documentation of the work sent to a specific contact, let us know when you call. Landlords and property managers often need records for their own files or for a tenant's reference, and we can make sure the right person receives what they need.
Not the biggest name in town. Just the one that answers. No runaround.
Whether you have a sparking switch that needs attention today or a panel that has been on the list for two years, the process is the same: call, get the price, schedule the visit. Summit Electric is open every day from 9:00 AM to 9:00 PM. A small job is worth a call, not a wait.

Below is a quick look at the electrical services we handle for homes, rentals, and businesses in Johnston and across Polk County. Each row covers what the service includes, who it fits best, and a practical note to help you think through the job before you call. If a service is not listed or your situation does not fit neatly into one category, call us and we will walk you through it.
| Service Type | What's Included | When You Need It | Things to Know |
|---|---|---|---|
| Outlet & Switch Installation |
| Homeowners upgrading older outlets or adding new ones in kitchens, baths, garages, or outdoors | Current code requires GFCI protection in kitchens, bathrooms, garages, and outdoor locations. Many older Johnston homes are missing these entirely. |
| Basement & Sump-Pump Circuits |
| Homeowners finishing a basement or adding sump protection in an Iowa home | A sump pump on a shared circuit can lose power at the worst moment. A dedicated circuit with proper GFCI protection is the right setup for any basement in a region with spring thaw and heavy rain. |
| Wiring & Circuit Installation |
| Older homes with outdated wiring or any property adding circuits for new loads | Johnston has a mix of housing ages. Knob-and-tube and aluminum wiring are both present in older neighborhoods and both present real concerns worth addressing. |
| EV Charger Installation |
| Homeowners adding a Level 2 charger in a garage or driveway | Older panels sometimes need an upgrade before a Level 2 charger circuit can be added. We check panel capacity first so any needed upgrade is identified and scheduled before installation day. |
| Electrical Panel UpgradesMost Popular |
| Homeowners with older panels, repeated tripping, or new loads like EV chargers that exceed current capacity | A 100-amp panel that was adequate in 1975 is often not adequate for a home that now has a home office, an EV charger, and a modern kitchen. We size the new service for what the home actually needs. |
| Electrical Safety Inspections |
| Home buyers, sellers, landlords, and owners of older homes with wiring that has not been reviewed in years | If the inspection turns up items that need attention, we explain what they are and what fixing them involves. You get the information before deciding on anything. |
| Dedicated Appliance Circuits |
| Anyone adding a high-draw appliance that needs its own breaker | High-draw appliances on shared circuits cause repeated tripping and can damage the appliance over time. A dedicated circuit is the correct fix. |
| Electrical Repairs & Troubleshooting |
| Any homeowner or renter with an unexplained electrical problem | We trace the problem to its source before recommending any work, so you know exactly what is wrong and what fixing it involves. |
| Lighting Installation |
| Homeowners, landlords, and commercial property managers updating or adding lighting | Exterior lighting for rental properties and commercial buildings often requires a new circuit rather than tapping an existing one. We confirm capacity before running wire. |
| Breaker & Fuse Repair |
| Homes with breakers that trip repeatedly or fuse boxes that need attention | A breaker that trips under normal load often points to an overloaded circuit or a failing breaker, not just a nuisance. We find out which before touching anything. |
| Whole-Home Surge Protection |
| Any Johnston homeowner concerned about lightning strikes or utility voltage fluctuations | Central Iowa sees significant lightning activity in storm season. A panel-mounted surge protector covers every circuit in the house, not just what is plugged into a power strip. |
| Wiring for Additions & Remodels |
| Homeowners finishing a basement, adding a room, or remodeling a kitchen or bathroom | Electrical rough-in is one of the first trades on-site in a remodel and one of the last to finish. We coordinate around the project schedule so the work does not hold up other trades. |
| Ceiling Fan Installation |
| Homeowners replacing a fixture or adding a fan where no wiring currently exists | If there is no existing wiring, we install a proper brace box rated for the fan weight so the ceiling support is correct from the start. |
| Backup Generator Installation |
| Homeowners in Johnston who want power protection during Iowa ice storms and severe weather | A properly wired transfer switch isolates the generator from the utility line, which protects both your equipment and line workers restoring power in the area. |
| Older-Home Rewiring |
| Owners of pre-1970s homes in Johnston with wiring that has never been updated | Rewiring an older home is a significant project, but it is often the only way to make the electrical system safe and capable of carrying modern loads. We scope the work carefully before any walls are opened. |
