"Raymond and his team did an amazing job. They ran a new power line from Edison's pole to a new building on my property and installed a new electrical panel. They also ran the wiring underground to my home and created a sub-panel for power. They also installed numerous outlets for lights, including a 220v for power tools & replaced a fan motor from an existing attic fan. They did a wonderful job. They made some recommendations that I didn't even think of. They pulled permits, met with city inspectors, and worked side-by-side with linemen from Southern California Edison, without any issues. Where I believe this company really shines is in their professionalism. They return calls, they show up on time, are respectful and reasonably priced. I highly recommend them to my family and friends. I will definitely be using them again in the future. A+++"

"After meeting with a few different contractors, I went with 1 Degree Construction because Thai just got it. He didn’t try to upsell me or push a trendy design—he actually listened to what I needed and helped tailor the kitchen around my family’s lifestyle. They were incredibly professional and the crew was surprisingly quick and efficient. What stood out most was the communication—I never had to chase anyone down for updates. Everything from demolition to final installation ran smoothly, and the final result blew me away. The cabinets are solid wood, not some flimsy prefab stuff, and the tile work looks like something out of a magazine. I honestly enjoyed the process, and that’s not something I thought I’d say about remodeling."

Subcontracting services FAQs
One starting point to find a local home builder is to collect suggestions from friends and neighbors. However, it’s still wise to do some more research before you hire a builder. Read reviews to supplement any word-of-mouth recommendations. Check sources like Angi that have standards and criteria in place to screen the pros it lists can also help you find more reputable local home builders.

Qualified, licensed electricians will charge from $50 to $100 per hour. The cost to hire an electrician for emergency visits may range from $100 to $200 per hour because this urgent service usually takes place during off hours and may require an electrician to leave or reschedule jobs they’re currently working on. Scheduling work on holidays or during periods of high customer demand, like after a major storm, will also lead to higher rates or extra fees.
