Fixed or venting

A fixed skylight only lets in light. A venting one opens to let out heat and moisture, which helps in bathrooms and kitchens, and many have rain sensors and remotes. The calculator prices a venting skylight as the fixed installed price plus the gap between Fixr's venting and fixed unit prices.

New opening or replacement

Replacing a skylight in the same opening is the simpler job. A new skylight means cutting the roof, framing the opening and building a light shaft through the attic to the ceiling, then drywall and paint. Today's Homeowner says prices can start as low as $250 to swap a basic unit and exceed $3,000 for bigger projects.

A worked example

One fixed skylight at the US average: $1,050 to $2,000, $1,500 typical. Three fixed skylights: $3,150 to $6,000, $4,500 typical. Enter a ZIP to scale the 40% labor share to your state.

Quoting skylights
