Electrician
The one job in the house where the lowest bid is the one to question, not the one to take.
What an electrician actually covers, and when you need one
An electrician handles everything behind the outlets and switches: the main panel, the circuits and breakers, and the wiring running through the walls and ceiling. Small jobs include adding an outlet or replacing a switch. Larger jobs include a full panel upgrade, rewiring an older house room by room, or adding circuits for a renovation. Almost everywhere this work is licensed and permitted, because wiring done wrong is a fire risk, and there is no safe shortcut on a panel.
Age is the most common reason to call one before anything actually breaks. Older homes often carry wiring types no longer considered safe by current standards, an undersized panel that cannot support modern loads, or a fuse box instead of breakers. None of this announces itself with a spark; it tends to surface first at a home inspection, or when an insurer asks about panel and wiring age before renewing a policy.
Call immediately for a burning smell, a warm outlet or switch plate, a breaker that trips repeatedly, or flickering lights not explained by a bulb. Call on a planned basis for any renovation that adds real load, since undersized capacity is one of the most common, and most avoidable, problems an electrician gets called to fix later at a higher cost.
This trade also sits underneath several others in this guide. A solar installation, an EV charger, and a standby generator are all, at some level, an electrician's job wearing a different name, since each one depends on the panel having room and the wiring being sound before anything else gets added. A homeowner planning any of those bigger projects is often better served starting with an electrician's clear read on the panel, rather than starting with the flashier project and discovering the panel is the actual constraint partway through.
How to choose one, and where this hire goes wrong
Confirm the license before anything else, and ask who pulls the permit on any job that needs one; requirements vary enough by state that it is worth asking directly rather than assuming. A good electrician also explains what they found in plain language and shows you, rather than simply naming a part and a price. If a breaker keeps tripping, ask what is actually causing it.
Replacing the symptom without finding the cause is the single most common way this hire goes wrong: the problem returns weeks later, and you pay for a second visit to solve what should have been solved the first time. Get a written scope for anything beyond a simple repair, and get more than one quote for a significant job like a panel upgrade, since the gap between quotes is often a gap in what is actually being done.
Watch closely for a bid that comes in far below the others with no permit involved and no paperwork offered. On electrical work specifically, that combination is not a discount, it is the removal of the inspection that exists to keep the work safe, and it is the one trade here where cutting that corner carries the most risk.
It is also worth asking, on an older house, whether any past electrical work was ever done without a permit, since an electrician who finds unpermitted work mid job is now responsible for deciding whether to bring it up to code as part of the current project, and that conversation is far better had upfront than discovered halfway through. Get everything in writing, including what happens if opening a wall reveals wiring that needs more than the original scope covers; agreeing on that process before it happens is what actually protects you, not a verbal assurance that it probably will not. A short reference from a recent, similar job, ideally one you can actually call, tells you more than a stack of general reviews.
What actually drives the cost
Scope is the largest factor by far. Adding a single outlet is a small, contained job. A panel upgrade is bigger, since it touches the whole electrical system at once. Rewiring an entire house is bigger again, closer to a renovation than a repair. Age and access change the number nearly as much: an older house with plaster walls and no attic access costs more to wire than open new construction, because the electrician works around the house's structure rather than through open space.
Permits and inspection add a real, necessary cost on top of labor for anything that requires them, and that is normal, not a markup to resent. Timing plays its usual role too, an emergency call for a dead circuit costs more than the identical job booked as a scheduled visit.
Fixture and equipment choice is a smaller lever on top of all this. A basic panel replacement costs less than one sized up for future additions like a generator or an EV charger, and deciding which to install is worth doing once, with future use in mind, rather than upgrading twice.
Future proofing is worth pricing deliberately rather than by accident. If a panel is being touched anyway for one reason, adding capacity for a generator, an EV charger, or a future addition at the same time is usually far cheaper than paying for a second panel visit a few years later once the need is more urgent and less planned. The same is true of adding a few extra circuits while a wall is already open for a renovation, versus opening it again afterward for wiring that could have been included the first time. As with any trade in this guide, the emergency version of a job always costs more than the planned version of the identical job, which is the strongest argument for calling an electrician for a checkup before a renovation, a sale, or a new large appliance, rather than only after something trips or fails.
