Johnston Electrical Services has been wiring homes and businesses in Parker, Colorado since 1994. Whether you need a single outlet replaced or a full panel upgrade, we show up, assess the job honestly, and get it done right. We serve homeowners, landlords, property managers, and commercial clients throughout the area. Choosing the right electrical fix is easier than it sounds, and we make it even simpler by walking you through the work before anything begins. Expect no-pressure estimates, priced up front, so you know what you're getting into before we touch a wire. Schedule it. We wire it. You're powered. Call (720) 623-9659 for a quote.
We've handled everything from a flickering light to a full rewire, and the jobs in between are just as familiar to us. Tripping breakers, dead outlets, lights that buzz or dim, wiring that hasn't been touched since the house was built. These are the calls we get every week, and we know how to trace them down fast.
All work is performed by licensed electricians who know Colorado code and know what older homes in this area tend to need. We cover the full range of residential and commercial electrical work, including:
If the job involves power, we handle it. Leave the breakers to us.
Some homes need a full rewire. Others just need one outlet fixed. Either way, waiting days for an electrician is not always an option, and we get that. We offer same-day availability for many jobs and responsive scheduling for everything else. If something goes wrong after hours, we are reachable. Electrical problems do not keep business hours, and neither do we.
When you call, you will talk to someone who knows the area and can give you a realistic picture of what the job involves. We come out, look at the problem, and give you honest recommendations on repairs, never an upsell. If the fix is small, we tell you that. If the job needs more attention, we explain why before we proceed.
We serve residential customers, rental properties, and commercial accounts throughout Parker and the surrounding Douglas County area. Affordable rates. Flexible timing. Safe wiring. We'll sort the wiring and clean up after.
Here's what most people get wrong about their wiring: they assume the price will be a surprise. It does not have to be. We give you an estimate before the work starts, and we stick to it. No charges appearing after the fact, no scope that quietly expands without a conversation.
What affects the cost of electrical work? Scope matters most. A single outlet swap is a short visit. A panel upgrade involves a permit, a load calculation, new hardware, and a utility coordination step. Rewiring an older home takes more time than running one new circuit in a finished basement. We factor all of that in up front and explain it plainly.
We believe in no pressure and no gimmicks, just safe, solid wiring, and pricing that reflects the actual work involved. Call (720) 623-9659 to request an estimate on any job, large or small. Reach out and an electrician will follow up.
Parker sits at elevation in Douglas County, and the winters here are not mild. Sub-freezing temperatures, heavy snow loads, ice storms, and wind events are routine from late fall through early spring. Multi-day outages happen. Pipes freeze. Ice dams form along roof edges. These are not edge cases for local homeowners and property managers. They are regular seasonal concerns that call for specific electrical work done ahead of time. The three services below come up constantly in this area, and we are set up to handle all of them.
When a winter storm knocks out power in Parker, it can stay out for more than a day. For homes with electric heat, medical equipment, or working-from-home setups, that is a serious problem. We install standby generator systems and handle the full electrical side of the job: generator hookup, transfer switch installation, and the dedicated circuit and panel capacity the system needs to run safely. We work with the existing panel to confirm it can carry the load, and we wire everything to code so the system is ready when you need it most.
Older homes in the Parker area were not wired for today's electrical loads. Electric vehicle chargers, home offices, kitchen appliances, and electric heating all draw more power than a 100-amp panel was designed to handle. We perform 200-amp panel upgrades and service entrance upgrades, add subpanels where needed, and run load calculations to make sure the new setup is sized correctly. Permit-ready work and code-compliant installation are standard on every panel job we do.
Frozen pipes and roof ice dams are a real cost for homeowners in Douglas County every winter. Heat tape systems prevent both, but they need a properly wired dedicated circuit and correct exterior wiring to operate safely. We handle the electrical supply side of heat tape installations: running the circuit, installing the outlet or connection point, and making sure the wiring is rated for outdoor use in cold conditions. If you are dealing with a recurring freeze problem, getting the electrical work done right is the first step.
From older homes to new commercial builds, EV charger installation is one of the fastest-growing requests we get. A Level 2 home charger requires a dedicated 240-volt circuit, and the panel needs enough available capacity to support it. We assess the panel first, run the circuit, and install the charger in the location that works best for your garage or driveway setup.
For commercial accounts and fleet operators, we handle multi-unit charger circuits and can coordinate the panel capacity work that larger installations require. If your panel needs an upgrade before the charger goes in, we handle both in the same project. We keep your home powered and safe.
Property managers, business owners, and general contractors in the Parker area rely on us for commercial electrical work across a range of project types. Office build-outs, retail spaces, warehouses, and tenant improvement projects all fall within our scope. We handle commercial panel upgrades, branch circuit installation, electrical rough-in and finish work, and permit coordination for jobs that require it.
Remodel and renovation electrical work is a regular part of our commercial workload. If you are reconfiguring a space, adding circuits for new equipment, or upgrading an older service entrance to meet current code, we can scope the job and get it scheduled. We work with property managers who need reliable scheduling and with contractors who need a responsive electrical sub on the job.
We're proud to be the local electricians this community calls first. That means something to us. When you call, you reach someone who knows Parker, knows the neighborhoods, and knows the kind of electrical work that comes up in homes and buildings around here.
We serve Parker and the surrounding communities throughout Douglas County, including Castle Rock, Lone Tree, Franktown, Highlands Ranch, Elizabeth, Centennial, and the southern edge of Aurora. If you are nearby and need an electrician, there is a good chance we have worked in your neighborhood before.
Thirty-plus years of electrical work in this area has taught us a lot about what local homes need and what local customers expect. Honest work, clear communication, and a job site left cleaner than we found it. Reach out and an electrician will follow up.
Choosing the right electrical fix is easier than it sounds, especially when you have a contractor who knows what a remodel actually requires at each phase. Kitchen and bathroom remodels need updated circuits, GFCI protection, and sometimes a dedicated line for a new appliance. Basement finishing projects need new circuits run before the walls go up. Home additions require wiring that ties back into the main panel cleanly and meets current code.
We handle the electrical scope on all of these, including permit-ready rough-in work and final inspection-ready finish wiring. If you are planning a project and need an electrician involved early, that is the right call. Getting the wiring roughed in correctly saves time and rework later. Call (720) 623-9659 to schedule a quote before your project breaks ground.
We serve Parker and the surrounding communities throughout Douglas County, including Castle Rock, Lone Tree, Highlands Ranch, Centennial, Aurora, Elizabeth, and Franktown. If you are nearby and unsure whether we cover your address, call (720) 623-9659 and we will let you know right away.
Same-day availability is offered for many jobs depending on current scheduling. For less urgent work, we typically get out within a day or two. Call (720) 623-9659 and describe what you need, and we will give you an honest estimate of how soon we can arrive.
Call (720) 623-9659 and tell us what you are dealing with. We will ask a few questions about the problem, give you a realistic picture of what the job involves, and get you on the schedule. No forms, no waiting for a callback from a stranger.
The more detail you can share, the more accurate the estimate. Useful details include the type of problem or work you need, the age of your home, whether you know the panel size, and where in the house the work is located. We will ask follow-up questions if we need more before giving you a number.
We work with property managers, landlords, and commercial accounts regularly, not just individual homeowners. Rental units need code-compliant wiring and reliable scheduling, and we understand that a delayed repair can affect a tenancy. Call to discuss your account needs and how we can support your properties.
A single tripping breaker or a dead outlet is usually a repair. Recurring problems across multiple circuits, a panel that runs hot, or a home adding significant new electrical loads like an EV charger or home office often point toward a panel upgrade. We assess the situation when we arrive and explain what we find before recommending anything.
Stop using the outlet or the circuit immediately and do not plug anything else into it. If the panel itself is sparking or you smell burning, shut off the main breaker if it is safe to do so and call us right away. These are not problems to wait on.
Flickering or dimming lights, outlets that are warm or discolored, breakers that trip repeatedly, and a burning smell near any electrical fixture are all signs that something needs attention. Any one of these warrants a call, not a wait-and-see approach.
For non-urgent work, a few days to a week is typical depending on the season and current demand. For urgent problems like a tripping breaker or a dead circuit, call the same day and we will do our best to get out quickly. Parker winters tend to drive higher demand for generator and panel work, so booking ahead for those jobs is a good idea.
The estimate we give you before work begins covers the labor and standard materials for the job as described. If something unexpected comes up mid-job, we stop and talk to you before proceeding. You will not see charges appear after the fact without a conversation first.
The core electrical work overlaps, but commercial jobs involve different code requirements, load calculations, and coordination with other trades. We handle both, and we adjust our approach based on whether the job is a home repair or a business fit-out. The same honest pricing and scheduling standards apply either way.

We handle the full range of residential and commercial electrical work in Parker and throughout Douglas County. Whether you need a quick repair or a major panel upgrade, every job gets an honest estimate before we touch a wire. Here is a plain-language look at what we offer, who each service fits, and what to expect when you call.
| Electrical Service | What It Covers | Ideal For | What to Keep in Mind |
|---|---|---|---|
| Heat Tape Installation | dedicated circuit for heat tape, outdoor-rated wiring and connection, pipe and roof edge applications, GFCI-protected outlet installation | Douglas County homeowners dealing with frozen pipes or recurring roof ice dams each winter | Heat tape systems require a properly wired dedicated circuit and outdoor-rated wiring. Incorrect wiring is a fire risk. We get the electrical side done right. |
| Dedicated Appliance Circuits | dryer and range circuits, hot tub and spa circuits, workshop and garage circuits, well-pump and block-heater circuits | homeowners adding a major appliance, a workshop, or outdoor equipment that needs its own circuit | A dedicated circuit prevents overloads and protects the appliance. We size the circuit correctly for the load from the start. |
| Electrical Repairs & Troubleshooting | flickering or dimming lights, dead outlets and switches, tripping breakers, buzzing or warm fixtures | homeowners and landlords dealing with recurring or sudden electrical problems | Most repairs are diagnosed and completed in a single visit. Warm or sparking outlets should be called in the same day. |
| Breaker & Fuse Repair | breaker replacement, fuse panel assessment, circuit fault diagnosis, panel interior inspection | homes where a single circuit keeps tripping or a breaker no longer holds | A breaker that trips repeatedly is not just an inconvenience. It often points to an overloaded circuit or a wiring fault that needs attention. |
| Wiring & Circuit Installation | whole-home rewiring, addition and remodel wiring, new circuit runs, rough-in and finish wiring | homeowners finishing a basement, adding a room, or updating wiring in an older home | Permit-ready rough-in work and final inspection-ready finish wiring are standard on every project we take on. |
| Backup Generator Installation | standby generator hookup, transfer switch installation, dedicated generator circuit, panel capacity assessment | Parker homeowners who need reliable power through winter storms and multi-day outages | We handle the full electrical side of the installation. The transfer switch is wired to code so the system cannot back-feed the utility line. |
| Whole-Home Surge Protection | panel-level surge protector installation, protection for sensitive electronics, whole-home and point-of-use options, post-storm assessment | homeowners with home offices, entertainment systems, or smart-home equipment vulnerable to voltage spikes | A panel-level surge protector is the first line of defense. It does not replace point-of-use protection for high-value electronics, but it handles large surges at the source. |
| Lighting Installation | recessed and can lighting, security and motion-sensor lights, landscape and outdoor fixtures, under-cabinet and accent lighting | homeowners upgrading interior lighting or adding exterior security lighting | Outdoor lighting circuits need weatherproof wiring and proper GFCI protection. We handle the full installation from circuit to fixture. |
| Outlet & Switch Installation | GFCI and AFCI outlets, USB and smart outlets, dimmer switches, outdoor and weatherproof receptacles | homeowners updating older outlets, adding kitchen or bath protection, or installing modern switch controls | GFCI protection is required by code in kitchens, bathrooms, garages, and outdoor locations. Older homes often lack it. |
| Electrical Safety Inspections | full-home wiring inspection, code-violation identification, older panel and wiring assessment, pre-purchase or insurance inspections | buyers, sellers, landlords, and homeowners who want to know the condition of their electrical system | Older homes in the area often have wiring that has not been evaluated in decades. An inspection gives you a clear picture before problems develop. |
| Ceiling Fan Installation | fan and light combo installation, existing fixture swap, new ceiling box and wiring, remote and switch wiring | homeowners replacing a light fixture with a fan or adding a fan to a room that lacks one | Rooms without an existing fan-rated box need a new ceiling box installed before the fan goes up. We check and handle that as part of the job. |
| Electrical Panel & Service Upgrades | 200-amp panel replacement, service entrance upgrade, subpanel installation, load calculation and permit coordination | homes adding EV chargers, electric heating loads, home offices, or major appliances that exceed the current panel capacity | Panel upgrades require a permit and utility coordination. We handle both and make sure the finished work passes inspection. |
How do I know if my home needs a panel upgrade?
A few signs point clearly in that direction. If your breakers trip regularly under normal use, your panel runs warm to the touch, or you are planning to add a significant new load like an EV charger or electric heating, your current panel may not have the capacity. Homes with original 100-amp service are especially likely to need an upgrade. We assess the panel when we arrive and explain what we find before recommending anything.
What causes a breaker to keep tripping?
Repeated tripping usually points to one of three things: the circuit is overloaded with more load than it was sized for, there is a fault somewhere in the wiring or a connected device, or the breaker itself has worn out and no longer holds correctly. We trace the cause before we replace anything, so the fix addresses the actual problem.
Is the electrical work permitted and inspected?
Yes, on jobs that require a permit under Colorado code. Panel upgrades, service entrance work, and significant new wiring all require a permit and a final inspection. We handle the permit process and make sure the work is inspection-ready before we close up. You get documentation that the work was done to code.
Upfront Quotes With No Surprise Fees
We give you an estimate before work begins and we stick to it. If scope changes mid-job, we stop and talk to you first. No charges appear after the fact without a conversation.
How do estimates and pricing work?
We give you an estimate before any work begins and we stick to it. If something unexpected comes up mid-job, we stop and talk to you before proceeding. The estimate covers labor and standard materials for the work as described. You will not see charges appear after the fact without a conversation first.
Can I get same-day service for an urgent electrical problem?
Same-day availability is offered for many jobs depending on current scheduling. For urgent problems like a sparking outlet, a dead circuit, or a tripping main breaker, call us the same day and we will do our best to get out quickly. Electrical problems do not keep business hours, and we are reachable when something goes wrong after hours.
What does flickering or dimming lights usually mean?
Occasional flicker when a large appliance starts up is often normal. Persistent flickering, dimming that happens across multiple rooms, or lights that flicker without an obvious cause can point to a loose connection, an overloaded circuit, or a problem at the panel. These are worth a call rather than a wait-and-see approach.
Work Performed by Licensed Electricians
Every job on our schedule is handled by licensed electricians who know Colorado code and know what homes in this area typically need. That is the standard on every call, large or small.
Why would an outlet or switch stop working?
The most common reasons are a tripped GFCI outlet somewhere upstream on the circuit, a tripped breaker, a loose wire connection at the outlet or switch itself, or a failed device. GFCI outlets in bathrooms, kitchens, and garages protect other outlets on the same circuit, so a tripped GFCI in one room can kill power to an outlet in another. If resetting the GFCI does not restore power, call us.
Is it safe to do electrical work myself?
Minor tasks like swapping a light bulb or resetting a tripped breaker are straightforward. Anything involving wiring, opening a panel, running new circuits, or replacing outlets and switches carries real risk if done incorrectly. Wiring errors cause fires and shock hazards that may not show up immediately. Work performed by licensed electricians is the right call for anything beyond the most basic tasks.
Experienced With Older and Newer Homes
Parker has a mix of homes built decades apart, and the electrical needs differ significantly. We are comfortable working in both older homes with aging wiring and newer builds that need circuits added for modern loads.
What do I need to know before installing an EV charger at home?
A Level 2 home charger requires a dedicated 240-volt circuit, and your panel needs enough available capacity to support it. We assess the panel first, confirm the capacity, run the dedicated circuit, and install the charger in the location that works best for your garage or driveway setup. If the panel needs an upgrade before the charger goes in, we handle both in the same project.
How does a backup generator installation work?
We handle the full electrical side of the installation: generator hookup, transfer switch installation, and the dedicated circuit and panel capacity the system needs to run safely. The transfer switch is wired so the generator cannot back-feed the utility line, which is a code requirement and a safety requirement. We confirm the panel can carry the generator load before anything goes in.
Do I need to be home while the work is done?
For most jobs, yes. We need access to the panel, the work area, and occasionally other parts of the home to trace circuits or run wiring. If you have a specific situation, such as a rental property where you cannot be present, call us and we will work out the access details in advance.
Call (720) 623-9659 and we will walk you through what your job involves, give you an honest estimate, and get it on the schedule.
