Everything from the quotation, install scheduling and installation went perfectly. They installed the skylight on October 16, 2018.
The only small thing that went wrong is a small piece of weatherproofing tape by chance fell into our halogen hall light which we luckily noticed at night before it caught fire. The hall light was not easy to get at but we managed to remove the debris. It was a freak but potentially hazardous occurrence but we solved it without incident.
The other aspect that never occurred to us is that the glass tint and gas fill of quality skylights slightly changes the colour of the indoor walls during daylight. We image it could be a big deal for sensitive paint colours but it wasn't for us.
That said we would use Skylights Unlimited again without a doubt. It was a pleasure dealing with Brady, the estimator. He knows skylights.
