I had my skylight installed towards the end of the season and dealt with Jeff. I chose the Velux Solar Opening Skyligh (VCS 2246). Jeff assisted in the selection, was prompt with his installment appointment, took pictures of his work at different stages (even though I was able to go up to the roof with him to look at his work).
I held off the review until I have a chance to use the opening feature of the skylight.
The product
The skylight itself is beautiful and well manufactured. The brand speaks a lot for itself. The opening feature is great for exchanging air in the skylight channel leading up to the roof. It doesn't lower the temperature on the 2nd floor as dramatic as I had thought (maybe 1 degree difference with it opened). However, it is a great feature to have and air do get freshened in a hot day.
The Service
Jeff showed he is knowledgeable in his work. He took the skylight up to the roof and down with the old skylight with ease. His transparency (taking photos) of steps installing the skylight is appreciated and certainly make me comfortable. As you may not go up to the roof to check his work, this is valuable.
Conclusion
Good Product, good service, good guy.
