"Installed the bathroom fan/light which wasn’t super easy, they had to crawl through insulation in the attic. Also changed out the broken switch on the outlet while they were there which was nice. Not terribly pricey"

"I hired Elevate Electric to install multiple electrical outlets in my basement after a waterproofing project. Kyle installed electrical outlets, ran a new circuit, and upgraded a breaker. The result looks outstanding! The new circuit wire is routed cleanly and he even dressed up some previous wiring too. Kyle shaped conduit around existing items along the basement wall making the whole utility room look good. This is probably the 4th time I have hired Kyle for electrical work. He consistently does great work. The quality is top notch and his pricing is extremely fair. You cannot go wrong with Elevate."
