We had an acrylic dome skylight that was acting like a magnifying glass in our 3-storey townhouse. We wanted to replace the skylight with an energy-efficient, low-e, glass skylight with an integrated shade.
With other companies, we received one quote by phone, and then an inflated quote when the representative came out to see us. I guess they sized us up as being able to "afford" a premium for the install. Not so with Skylights Unlimited. Their quote was competitive, consistent, and when we added extras (solar-powered shade, venting) the cost only went up marginally (only by the amount that Velux charged for the extra -- not a special, nice-home premium).
To top it off, the team was professional, efficient and (we could hear them on our roof) took extra steps to do the job well. We needed an extension rod for our cathedral ceiling (we opted for the manual venting skylight, not electronic) and someone from Skylights Unlimited drove it over to our place the next week. No extra charge.
