This was a hassle-free transaction. It wasn't a huge job - installation of one indoor sconce and two outdoor sconces, including all wiring and switches. Inside, the plaster walls needed to be channeled to accommodate the wiring.
I mostly dealt with Paul who was professional, efficient, and respectful. He came to look at the job within days of my call. The very reasonable estimate was faxed a day later. We scheduled the job, and the insurance certificate (meeting the requirements for my co-op apartment) arrived well before the scheduled date. Paul's wife was due to give birth on the day of the job so he asked if he could send someone else, who turned out to be his equally professional and nice brother.
When the bill arrived, it was a little less than the estimate. These guys are great.
Pros: Pricing, efficiency, reliability
