We hired MZ electric to install recessed lighting in a remodel, in existing sheetrock, with no physical access to an attic. These guys did an absolutely fantastic job. They worked with us on the design and walked through where we would put all the lights before they cut holes. It feels like we have a new home - we are SO happy with how it all turned out. The install team was punctual, professional, explained everything along the way, and cleaned up after themselves. They also installed an outlet for us behind our tv so we could hide our tv cords. I wholeheartedly recommend them!
