Most professional electrician I have known in my life…read more Highest quality work at all time. Amiable and neighborly always. Very reasonable rates. Works hard on site and delivers excellent service. I would trust him with my life. (I did. He was first on the scene with EMTs when my car door drug me on my driveway fifty feet.) A true asset to Denville community and humanity. Don't forget Tina. She's the heart and soul behind the scenes. Always a pleasure to talk to regarding scheduling and communications. Michael Allgaier

He took off plate and looked, that's it! What a rip off! And he was huffing and puffing the entire time, very heavy man. I ended up calling First Class Electric. He came over and inspected everything and knew what was going on. He didn't charge me first visit and set up a day to come back. When he came back he did everything in ONE HOUR! The power that SEV didn't know how to fix was just needing new light switches, SEV couldn't figure that one out? RIPOFF! Don't use this this electrician!

Dawson Mechanical was instrumental in my successful switch from oil to gas heat when they installed…read moreNavien combi units in my home. The install was executed flawlessly and the cost per value for the product and service was reasonable. Dave and his staff Wanda, Ricky and William were knowledgeable and professional. Dave walks you through the process step by step and was accommodating to answer my numerous questions. When the inspectors came on two different occasions they both asked who did this job because they said you don't see craftsmanship like this anymore. I look forward to working with Dawson Mechencal for the maintenance of these units for years to come.

You will not be disappointed. If you need any plumbing, Dawson is the way to go.

I was nearly finished making some renovations to my master bathroom when I decided that I wanted to…read moreinstall recessed lights. My shower door guy urged me to do that before he installs the new shower door. So, I needed an electrician who could install my lights lickety-split. My contractor's electrician, who did the wiring for the heated floor, was too busy to install my lights. Therefore, late Sunday afternoon, I came to Yelp to find a good local electrician, who had the ability to do the job this week. Lucky me: I found Jason Klein. I was immediately impressed with his many great reviews. I used the Yelp platform to create a project SPECIFICALLY addressed to Jason. I explained my urgency to complete the lighting installation this week so that my shower door can be installed next week. Jason responded via Yelp's platform almost immediately. Wow! He said that he could do the project on my timeframe. Long story short, Jason's crew showed-up a little before 10 a.m. today, Wednesday, and they finished before noon. The guys installed 6 new recessed lights (3 in my bathroom and 3 in my closets). They were polite and they did a great job. The icing on the cake is that they were very neat: they wore booties inside (YES!), they laid-down tarps on the floor (Thank you!!) they covered the clothes in my closets with plastic (WooHoo!!!) and they vacuumed (Doing my Happy Dance!!!!). Throughout the process, Jason stayed in contact with me by phone/text, so I knew what was going on and exactly when his guys would arrive. I'm very pleased with Jason Klein Electric and I will definitely use them again. (I'm renovating my kitchen next.) (As an aside, I'm a bit dissatisfied with Yelp's tool for creating "Projects." I thought that I had selected a specific electrician from whom to request a quote. I included my phone number in the details. I was disappointed to find that my Project had been shared with others, who also responded. Some of them did not appear to be licensed electricians. I sent an email to Yelp's Privacy Officer inquiring as to whether that was appropriate. No response yet. No matter. I won't use that Project tool again.)

Two young employees arrived. I asked them to spread a tarp since there would be drywall dust and…read morebits of debris as a result of the planned work. When they put down the tarp, I noticed it was VERY dirty, with tiny pieces of drywall debris on it. I asked them to remove it and then shake it outside. When they lifted it from the floor, I saw that the floor was coated with white drywall dust. So *both* sides of the tarp were dirty. Lack of attention to detail and lack of respect for the client's home. Not ok. At some point I suggested we cover the granite countertop where one of the employees was working to protect it from damage in case a tool should accidentally drop on it. Instead of accommodating my (reasonable) request, he resisted, saying "Nothing will drop". Not ok.
