Why homeowners hand us the wiring

A licensed C-10 runs the wire

A Class B license lets us hold the contract and run the job. The wiring itself is done by a licensed C-10 electrical contractor we bring on and manage. One contract, and one person answerable to you for it.

Licensed and bonded

CSLB # 1105333, Class B General Building, plus a $25,000 contractor bond through Travelers. Both are public record and both are linked further down this page.

Permits in the licensed name

A panel change is permitted work in every jurisdiction we cover. We pull it, we coordinate the shut-off, and we meet the inspector.

Change orders before the work

If the number has to move, you see why and you approve it in writing before anything else is built.

When a house needs an electrical panel upgrade

The panel was sized for a 1981 house, not for how you live now

The median home in San Bernardino County, CA was built in 1981. It was wired for one television, one air conditioner and a kitchen with four appliances in it. Since then you have added a second AC unit, a microwave, a dishwasher, a garage full of tools, and possibly a car that needs charging overnight. The panel has not changed. That is why the breaker in the kitchen trips every time the toaster and the kettle run together, and it is why there is no empty slot left to add anything.

There is a second problem underneath the first one. A house of that vintage was built before arc-fault protection, often before ground-fault outlets were required in every wet location, and sometimes with a panel brand that home inspectors now write up on sight. Older houses in San Bernardino, Colton and Redlands can still have aluminum branch wiring behind the drywall. None of this is urgent until it is, which is exactly why it gets left. What follows is what we would actually do about it, priced and scheduled in writing before anyone opens a wall.

What rewiring a house actually involves

What the electrical scope covers

Get a written estimate

Every line below is written into your scope before work starts, so there is nothing to argue about later regarding what was and was not included.

  • A load calculation, so the panel is sized to what the house actually runs
  • Panel or subpanel replacement, permitted, and the meter reconnect coordinated with the utility
  • Branch circuits rerun, grounded, and protected where the current code calls for it
  • Dedicated circuits for the AC, the range, the laundry and a car charger
  • Lighting, switches, fans, and smoke and carbon monoxide alarms
  • Drywall patched, textured and painted where we opened it, and the final inspection signed off

Start with the written scope

The next step is your job on paper

You have just read how the work runs. The next move is a walkthrough of your house, a written scope of what the job covers, and a schedule carrying the same stages. Ask for all three before you commit to anything.

Electrical load planning

Count what the panel must carry before adding another circuit

An open breaker space does not automatically mean the service has capacity. Heating and cooling, cooking equipment, water heating and future vehicle charging all belong in the load calculation. The condition and rating of the existing equipment matter too.

Start with the actual service, not the label on one breaker. That tells you whether the project needs a new branch circuit, a panel change or a larger service included in the scope.

Electrical access and repair

Plan the route through the house and the finish work that follows

New wiring may travel through an attic, crawlspace, garage or selected wall openings. The cleanest electrical plan is also an access plan that names where openings are expected and which surfaces will be patched and painted afterward.

Agree on that boundary before work begins. It prevents the electrical price from appearing complete while the homeowner is left with the separate job of restoring every access point.

Questions about Electrical

Straight answers before you commit

All questions
Who actually does the electrical work, and are they licensed?
We hold a California Class B General Building license, CSLB # 1105333, which is the license that lets us contract for and run a project that includes electrical work. The wiring itself is done by a licensed C-10 electrical contractor we bring on and manage. That is how it is meant to work, and it is better for you than the alternative: you get one contract, one schedule, and one company answerable to the building department and to you if something is wrong.
How do I know whether my panel actually needs upgrading?
The usual signs are breakers that trip when two ordinary appliances run together, a panel with no spare slots left, 100 amp service in a house that has since gained a second AC unit, or a panel brand that inspectors flag on sight. None of those is proof on its own. We do a load calculation for your house and show you the arithmetic, rather than selling you a bigger panel because bigger sounds safer.
Do I need a permit to replace a panel?
Yes. A service panel change is permitted work everywhere we operate, and the utility has to be involved to disconnect and reconnect the meter. We pull the permit in the licensed name, CSLB # 1105333, book the shut-off, and meet the inspector. That is our job, not yours.
Can you rewire a house while we are living in it?
Usually, yes. A rewire is normally done in sections so that the house is back on power at the end of the day, and your written schedule says which rooms are affected on which days and which hours the power is genuinely off. If the scope means a stretch without power that you cannot live around, we tell you that before you sign, not on the morning it happens.
What does electrical work cost?
We do not publish a number for this one, because there is no honest range to publish. A panel swap in an accessible garage and a full rewire of a two-story house with finished walls are not the same job in any respect. What drives it is the amperage, how far the wire has to travel, how much wall has to come open, and how much has to be brought to current code once it is open. We look, then we put a number in writing.
Will you patch the drywall you cut open?
Yes, and it is written into the scope rather than left as an assumption. Patching, texture matched to the surrounding wall, and paint are part of the job. This is one of the practical arguments for having a general contractor hold the work: the trade that opens the wall and the trade that closes it are under the same contract.

How your electrical work runs

A written schedule, and what happens once the walls are open

The full process

Schedule of work

Electrical · CSLB # 1105333

  1. We come and look at the panel

    We open the panel, read what is in it, count the circuits you have against the ones you need, and look at what is reachable in the attic and the crawlspace. There is no charge for this and no expectation that you decide anything on the day.

  2. You get the scope and the number

    A written scope, a written schedule and a written number, with the load calculation behind it and the circuits listed out. Take as long as you need with it. Nothing is ordered and nothing is opened until you sign.

  3. We do the work, and we close it back up

    Permit pulled, power scheduled so you know which hours you are without it, inspection met, then drywall patched and textured back. The site gets swept at the close of every day, because you are still living here.

If we find something

Opening a wall sometimes turns up rot, old wiring, or a leak nobody knew about. When that happens the work stops and you get a written change order with the new scope and the new number. Nothing further is built until you sign it. You will never learn about an extra cost from the invoice.

Permits are pulled in the licensed name, CSLB # 1105333, and we meet the inspector. That is our job, not yours.
