These guys did great work on our house! I work in construction, and I was wary of having just anyone cut into my roof and framing, which is why I went with Skylight Specialists. They are a certified Velux installer, and they work together with certified drywall company to provide full-service installation and repair. Our install was a little more complicated because we wanted a big skylight with a skylight well in our kitchen. It required some additional framing and moving of electrical, but the installers were professional and accommodating at every step. They put down and removed site protection every single day they were on site, and made sure to leave the space in usable condition at the end of each day. Our attic access is really small, but they never complained about having to crawl through the tight space. We got some minor pushback about filing a building permit with the city, but in the end, they handled the submittal and inspections for an additional fee as we discussed. In the end, it turned out even better than I imagined, and we are now considering adding a second skylight in our entry, as well as several Sun tunnels throughout the house. The complete installation took 2 days, with final drywall texturing and finishing happening a couple weeks after. Every time I stand in my kitchen, it makes me happy.
