Caulder Electric is your go-to for anything electrical. We analyzed dozens of reviews spanning over 15 years and found the same pattern repeated: Derek shows up on time, quotes the job accurately, and delivers work that holds up. One homeowner's solar system from 2010 is still running flawlessly today, hitting the exact energy savings Derek predicted at install. Another client called them back after five years of projects to handle solar, battery storage, and utility coordination on a historic home with tricky wiring. What stands out most is how they handle complexity without drama. They've wired 600-amp commercial panels, navigated Southern California Edison approvals for solar-plus-battery installs, and diagnosed confusing wiring in century-old homes. In one case, Derek drove out to investigate a suspected mistake from a prior job, confirmed his crew's work was correct, then stayed to walk the homeowner through their kitchen remodel wiring for free. (Yes, he troubleshot someone else's confusion and didn't bill for it.) We couldn't find a single complaint about workmanship, follow-through, or pricing accuracy across the entire review history.
If you want the cheapest quote in town, keep shopping. But if you're looking for an electrician who'll still answer your call 15 years after install and whose estimates actually match the final bill, Caulder Electric is worth the investment.
Dwight M. hired Caulder Electric in 2010 to design and install a solar system for his home. Derek’s energy‑savings projections matched the actual performance, and the array has run without issues ever since. Fifteen years on he recently replaced the inverters, and he continues to rely on Caulder for all other home electrical work, consistently extremely satisfied. The memorable detail: accurate forecasting up front and long‑term, trouble‑free operation that made later upgrades simple.
Bobby S. hired Derek and his crew for a panel upgrade on his home in Upland a couple years ago, and they finished the job quickly and cleanly. During a recent kitchen remodel he ran into some confusing wiring and feared the original install might have been at fault. Derek jumped on the concern with real urgency, came out to recheck the work, and discovered there was no mistake. Rather than brush him off, Derek spent extra time walking him through what to do in the kitchen to keep the family safe, answering questions and calmly explaining the wiring. Bobby appreciated the patience and kindness, and because Derek willingly revisited the job and helped him understand the safety steps, he and his team remain the first call for electrical work at the Upland house.
Pat N. has relied on Caulder Electric for about 11 years, calling them back for everything from replacing switches to troubleshooting difficult electrical line issues. Over that span they handled routine interior and exterior lighting work and, most recently, took on all the electrical for a new-build home: an upgraded service panel plus an extensive solar-and-battery installation. Caulder dug the necessary trenching and dealt directly with Southern California Edison, so the utility coordination didn’t fall on Pat. Whenever a concern popped up, Derek and his crew moved quickly, addressed the problem safely and neatly, and left the job to Pat’s satisfaction. The materials and level of customer service stood out as consistently high, and the team’s honest, straightforward, courteous approach made repeat work easy. The detail that stuck with Pat was the company’s willingness to shoulder complex tasks—like trenching and SCE coordination—so the homeowner could focus on the rest of the build.

Andrew D. has relied on Caulder Electric for years, turning to them for everything from quick home repairs to wiring the new houses he built—and trusting them to install a 600-amp panel in his commercial building. Over multiple jobs he encountered steady, reliable workmanship and crews who handled both small fixes and large-scale wiring without drama. What stood out most was the owner’s straightforward approach and the fact that he keeps his word, which made scheduling and coordination with builders simple. Because of that consistency, he gives Caulder’s number to contractors, neighbors, and anyone else who needs electrical work.

Ryan Z. has kept this solar company on speed dial, sending dozens of clients their way and hiring them himself multiple times. He discovered their installations are consistently solid and their pricing stays reasonable. Because the workmanship holds up and the cost doesn't surprise, he keeps returning to them for both client jobs and his own projects. The lasting impression: they’re not a one-off vendor but a dependable partner he calls back again and again.
