"Chris was flexible and worked with my on what type of mount was needed for a large and smaller TV. When he realized neither of us had the size mount needed to properly support the big TV, he went out and got what was required. He was professional, polite and got the job done for a reasonable rate."

" Dimitri has done a bunch of projects at my 1920s house including replacing some old wiring in the garage, removing an ancient alarm system, and putting in a bunch of new outlets and fixtures, indoors and outdoors. Rates are reasonable and Dimitri is great to work with -- reliable, professional, and helpful. I'll definitely work with him again for future electrical projects."

"Do not hire them to work off their retail price list. We were charged $640 for a two-hour job to replace two exterior lights and install a simple Ring Doorbell replacing an existing doorbell. We supplied the lights and Ring Doorbell. My issue is how they price and the fee we were charged. My mistake was not to accept a fixed price job from Home Advisor."

"The technician, Hugo, found that my daughter had blown a bathroom fuse. He swapped out the fuse for one that was working and then offered to buy a couple of packs of replacements, to which I agreed. He also suggested that the garage panel be replaced and told me what the probable cost would be. I was grateful for the information and for the creativity with which he approached the problem."
