5 miles from our San Dimas shop. We understand Claremont's historic homes, its preservation rules, and what it takes to modernize a mid-century electrical system without compromising the character of the house.
Nearly half of Claremont's homes were built in the 1940s-1960s, and most are still running on their original 60-100 amp panels. Federal Pacific Stab-Lok and Zinsco panels are everywhere in this housing stock — both are documented fire hazards that fail to trip during overcurrent. We upgrade to 200A and 400A service, pull the permit through Claremont's Building Department, and coordinate with SCE on the meter disconnect. If your insurance company is flagging your panel, this is why.
Claremont has four historic districts, a Register of Historic Structures, and an Architectural and Preservation Commission that reviews exterior modifications. If your Craftsman bungalow near the colleges or your Spanish Colonial in the Village is on the register, you can't just bolt conduit to the outside wall. We rewire historic homes from the inside — running new copper through existing wall cavities, avoiding damage to original plaster, lath, and woodwork. For Mills Act properties, we know the standards and work within them.
Claremont is one of the most educated, environmentally conscious cities in LA County — 59% of adults have a bachelor's degree or higher, and EV adoption here is well ahead of the curve. We install Level 2 chargers with a dedicated 240V/50A circuit for any vehicle. Since most Claremont homes have mid-century panels that can't handle the extra load, we typically do the panel upgrade and charger install in one project, one permit.
Claremont is the City of Trees — over 24,000 city-maintained trees and a Tree City USA designation for 30+ consecutive years. That canopy is beautiful, but mature trees on older streets grow into and around overhead service drops. Branches contacting service entrance cables cause arcing, insulation damage, and outages. During panel upgrades, we often need to reposition the weatherhead and service mast for proper clearance. SCE will temporarily drop service wires at no charge for tree work — we coordinate all of that.
The foothills neighborhoods — Claraboya, Padua Hills, Northeast Claremont — sit right at the wildland-urban interface with the San Gabriel Mountains. CAL FIRE classifies parts of north Claremont as Very High fire hazard severity zones. During Santa Ana wind events, SCE issues PSPS shutoffs that can leave you without power for days. We install whole-home standby generators that kick on automatically, and battery systems like Tesla Powerwall that pair with solar for year-round resilience.
We're 8 minutes away in San Dimas — right down Bonita Avenue. When a Santa Ana windstorm takes out your service drop, a branch falls on your weatherhead, or your panel trips and won't reset during a summer heat wave, call us any time. We know Claremont's streets, we know SCE's process, and we'll be there fast.
Claremont is the City of Trees and PhDs — a community that values craftsmanship, preservation, and doing things right. We share those values. Based 5 miles away in San Dimas, we've worked across Claremont's neighborhoods — from the Craftsman bungalows near Pomona College to the mid-century ranches in College Heights to the custom estates up in Claraboya. Each one has different electrical challenges, and we know what to expect before we open the panel.
What sets Claremont apart from other cities we serve is the preservation layer. Four historic districts, an Architectural Commission, Mills Act contracts, and homeowners who genuinely care about maintaining the character of their homes. That means you can't just slap a panel on the outside wall and call it done. We route new wiring through existing cavities, conceal conduit runs, and keep exterior modifications to a minimum. The goal is modern, safe electrical — without changing what makes the house a Claremont home.
49% of Claremont's 12,185 housing units were built between the 1940s and 1960s. That's the era of 60-100 amp panels, Federal Pacific and Zinsco breakers, possible aluminum wiring, and two-prong ungrounded outlets. The pre-1939 homes near the colleges — the Craftsmans and Spanish Colonials — may still have knob-and-tube wiring with degraded cloth insulation. Insurance companies are increasingly refusing to cover homes with these panels and wiring types. If you haven't had your system evaluated since the house was built, now is the time.
Claremont's four historic districts, the Register of Historic Structures, and the Architectural and Preservation Commission mean that electrical work on registered properties isn't just about code — it's about character. Exterior modifications like new service masts, panel relocations, and surface-mounted conduit may need Commission review. Mills Act homeowners have a contractual obligation to maintain historic character in exchange for their property tax reduction. We understand these requirements and plan around them, so your home stays on the register and your electrical system comes into the 21st century.
Claremont's urban canopy is one of the best in Southern California — but it creates real electrical service issues. Mature trees on older streets grow around overhead service drops, and branches rubbing against insulation cause arcing, shorts, and outages. During panel upgrades on tree-lined streets, weatherhead and mast positioning requires extra planning to maintain clearance. Underground conduit runs in established neighborhoods need to route around root systems. None of this is unusual for us — it's just part of working in Claremont.
