"We recently had our outdated kitchen completely remodeled by 1 Degree Construction, and I honestly can’t say enough good things. From the very first consultation, Thai (our project manager) was attentive, asked smart questions, and helped us shape the vision we had in mind—even better than we imagined. The team was quick, efficient, and always professional. What really impressed us was the communication. I always knew what was happening and when, and Thai checked in frequently to make sure we were happy with every stage of the project. The custom cabinets are stunning and the tile backsplash came out better than the Pinterest photo I had saved. Everything was finished in a timely manner and the price was competitive for the high level of quality. Wouldn’t hesitate to recommend them."

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.
