"I have found my forever electricians (at least while I live in the New Haven area)! From start to finish my experience with Power Forward was an absolute pleasure. Company owner, Ian, was responsive, punctual, and incredibly informative when it came to walking me through the details of the scope of work I was requesting, and was thoroughly transparent and fairly priced when it came to his estimate. Once we accepted the quote, scheduling with Morgan was easy and efficient, and Chris arrived onsite within a day of me accepting the estimate. Chris was a consummate professional, a super clean worker when it came to caring for our house and the cleanliness of his cable paths, and was truly dedicated to doing the job â the right wayâ not just the easy and cheap way. He took his time and planned his cable runs and circuiting carefully to ensure both minimal cutting into our walls and convenient receptacle placement. Once he was finished, he took care to clean every area heâ d worked in and probably left some of the rooms cleaner than when he arrived! I would recommend Ian and Power Forward to anyone who appreciates work that is done with care, safe, and efficient. I think you get what you pay for when it comes to hiring trade professionals, and electricity is not something you want to cut corners with: hire Ian and his team, and have it done right and safe the first time."
