An electrical panel upgrade on an older Claremont house can stop at the box on the wall, or it can reach the meter outside and the circuits behind the plaster. Those parts may date from different decades, and each one can change the price. Our visit checks all of them before we write a number.
Photograph the open panel and the meter outside, then list what you plan to power next. From those we can plan the visit and quote your panel upgrade.
Where a new panel fits in an older Claremont house
A panel job comes up for one of three reasons. A fuse box or small breaker panel has run out of spaces. A heavy new load is coming, such as central air or a car charger. Or a larger remodel is being planned and the panel has to carry it.
We price this as its own job, and it also works as the first stage of a whole home remodel. We work on houses built before about 1970, so the panel is rarely the only old part in the chain. Our quote shows you what the rest of that chain would add, and you decide how far to go.
Location matters on these houses. A new panel is often larger than the box it replaces, so a recess cut into lath and plaster may have to grow. If casing or a built-in sits close by, the quote says how that wood will be protected or pulled and put back. Moving the panel to a better wall is possible too, with a new feed and wall repair on their own lines.
What sets the price of a panel upgrade
Five items carry this quote, and only the first is the panel itself.
Panel size. Panels are rated in amps and counted in circuit spaces. A larger one costs more in parts and leaves room for later circuits. We size yours from the loads you have today and the ones you name at the visit, so the rating has a reason behind it.
Service drop and meter. Sometimes a new panel can sit on the existing service. If the line coming from the utility or the meter equipment is too small for the new rating, the job grows to include that equipment and a changeover arranged with the utility. Its calendar then goes into your timeline. We tell you which case you are in while we are on site.
Old wiring behind it. New breakers feed whatever circuits already run through the house. Cloth-covered cable, knob-and-tube and spliced runs may need work before they can land in the new panel. A full replacement is a larger scope, and our post on what a rewire costs covers it. When it makes sense, we quote the panel alone and the panel with rewiring side by side.
New loads planned. An electric range, a heat pump water heater, central air and a car charger each add demand. So does an ADU fed from the main house, or a kitchen remodel with new appliance circuits. Name them now, because any of them can raise the rating you need and pull the service along with it.
Permit. The City of Claremont's permit list names panel upgrades, repairs and relocations as work that needs one. The fee and the inspection trips get their own line. If your job also changes the service, we confirm with the city what that adds for your address before the quote is final.
Who should do this work, and what widens the job
Panel work belongs with a licensed crew, under permit, with an inspection to close it out. Ask each bidder who pulls the permit, and get the answer in writing. Ask too what the price covers: the panel alone, or also the service and any repairs to circuits that land in it. Two matching totals can describe very different jobs.
Three decisions move the scope most.
Panel now, or panel inside a larger job. If the wiring and pipes are also due, doing the panel as part of a full remodel lets the trades share the same open walls. We would steer you that way when the house calls for it. If a panel is all you want this year, we will price it that way.
Stay on the old wall, or move. A panel that stays keeps wall repair small. One that moves can clear a tight closet or a run of trim we want to save, at the cost of a new feed.
Size for today, or for the plan. If an addition or a structural job is a few years off, tell us. We can show the rating that covers today beside the one that covers the plan.
Our visit and the panel quote you get
At the house we take the cover off the panel, read its rating and look over the breakers or fuses. Outside, we check the meter and how the line reaches the house. A few cover plates come off in different rooms, so we can see what wiring the new panel would feed.
Your written quote then lists the panel rating and circuit count, any service and meter work, wiring repairs at the panel, wall repair and the permit. It also says when the power will be off on changeover day, so you can plan around it. Optional items sit below the base price, ready to add or drop. Anything the wall hides once it is open comes to you as a priced change before the crew goes on.
Photos and notes to pull together
- A clear shot of the open panel, with any rating label you can read.
- The meter, plus the point where the utility line meets the house.
- A list of large appliances, along with central air if you have it.
- Anything new you expect to add, from a car charger to an ADU.
- Past electrical permits or inspection notes, if you kept them.
- Rooms where breakers trip or fuses blow, and what was running at the time.
