"The provider came to give estimate for the emergency situation we were in for water leaking into electric panel box from electric pole attached to house outside. The provider suggested we upgrade Panel Box from 100amp service to 200amp service since box had to be changed anyway. The estimate was $400 higher than the other estimate we got from another ANGI electrician at $3100 but the provider could come the next day to complete job. Where the other electrian could not do the job for 4 days out. Provider stated that he doesnt accept credit cards or do financing so I told him "no thank you" to the job, as this was an emergency and didnt have cash to pay him. After Provider left he called back stating he could use an associate of his credit billing account so he can do the job. The provider NEVER mentioned getting PERMITS AND A UNDERWRITERS CERTIFICATE for us to upgrade the AMP service to our home. I hired this provider From ANGI believing he was a vetted Professional and we would have all proper services done including any and all paperwork involved especially that he was charging more for the job. After job was completed he still had no credit card available and was mad that I didnt have all cash. I was dumbfounded as he stated that he had access to a credit terminal. I gave him a Check for $1600 and a $100 bill Which then he gave me an invoice that had no Electrical License listed or any type of insurance listed. I had to actually call Suffolk County NY to find out if he actually had a license and insurance which I wrote down on attached file. Provider stated he had to get in touch for the credit. He called later with a link for PAYPAL for me to pay $1300 that I owed him which I paid asap. The provider then had to come back because he didnt attach our Oil Burner to the new Circuit Panel Box and it was freezing inside our home. He then approached me while my husband was still in the basement getting the oil burner started and was demanding another $100 because PAYPAL charged him FEES. I said bluntly "NO" and he started billigerently YELLING at me "YOU WANT ME TO EAT IT???" over and over. He left Slamming my front door while screaming outside extremely loud "SHE WANTS ME TO EAT IT???" meaning the extra $100. I called PAYPAL to ask about the tranaction and Payplal stated that he had to agree to their terms and fees which are on the business owners' and not the customers responsibility. He was very scary and I was afraid of him and was afraid he was going to retaliate against us some way. The PERMIT and UNDERWRITERS CERTIFICATE MUST BE FILED AND DELIVERED TO US as we only found out that this was MANDATORY by an Electrical Contractor that my daughter was hiring for same service."

Our staff of knowledgeable and dedicated professionals take pride in providing outstanding, personalized service to our customers and our community. All of our techs are factory trained and certified for warranty repair and maintenance. Call us today and become one of our many satisfied customers. You can visit us online at www.getgenready.com
"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."

FAQs for subcontracting projects in Islip Terrace, NY
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.

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.
