Skylights Unlimited was the most professional of the many companies I contacted off the internet. They came when they said they would, gave a reasonable estimate and start time, and worked with me as I changed the scope of the project to include replacing the water-damaged portion of a stipple ceiling as well as repairing the roof and replacing the skylight that had caused the water damage in the first place.
Even more impressive were the two workers who did the actual work. Did their work when they said they would, finished on time, and had minimal intrusion into my home. They even moved the protective plastic sheeting they'd set up when I had a major appliance delivered through their work area, and took pictures to show me the extent of the damage and the nature of the repair.
All the staff acted very professionally, something I don't see very often these days: polite, helpful, nice people.
Most importantly, their work is top-notch. Can't see where the ceiling was patched, and the new skylight and repaired section of roof is great. No surprises on the cost, and they finished when they said they would.
I'd use them again with pleasure.
