"We hired Bear Remodeling to convert our garage into an ADU for my mom to live in, and they knocked it out of the park! They handled everything. The team added proper insulation, installed new windows for natural light, and created a small but efficient kitchen area. They even finished the exterior paint to match our house perfectly. The transformation is incredible. You'd never know it used to be a garage. It took about 8 weeks from start to finish, which was actually faster than we expected. If you need more living space but don't want to move, I'd recommend their garage conversion service without hesitation."

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.
