"After getting several quotes, last year we hired GenReady to install a house generator. Ed, the owner of the company impressed us from the start. He was knowledgeable and patiently explained the process as well as answering our questions. We knew right away that GenReady was the company for us. Lindsay kept us up to date as we moved along in the process. Our generator was installed last July. Andrew and his team installed the generator with expertise and efficiency. They took care to leave our house and yard spotless. Lindsay and Andrew were always happy to answer my questions and address me concerns. We’ve needed the generator only once (thank goodness) when our power went out due to a necessary power line repair after a car crashed into a utility pole on our street. When the power went out, our generator turned on within seconds. Our house was up and running for the four hours the line repair took, and if it weren’t for the blink of lights, we never would have known our generator was running. Every other week, our generator self tests for a few minutes giving us peace mind that it will be here for us if and when we need it. Just like the generator, GenReady is a company that runs efficiently and seamlessly. Just today, Lindsay called to tell me someone would be coming tomorrow to change the oil which reminded me that I am long overdue in submitting this well deserved rave review. Thank you to the entire GenReady team (and to Great White Propane) for all you’ve done to help us know we can weather any power outage."

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.
