What to do. If you think you or someone else has broken their leg, go immediately to your nearest accident and emergency (A&E) department. Call 999 for an ambulance if the injury seems severe or you're not able to get to A&E quickly. While you make your way to A&E or wait for an ambulance:
A venting skylight usually costs between $300 and $600 for a manual version, and between $650 and $1,000 for an electric version with a remote control. Installation can run $300â$2,000 or more, depending on the size and complexity of the project.
Doing all this work requires more than one day and usually at least two workers. Depending on the details, adding a new skylight will cost anywhere from $2700 to $4500 for a fixed or manual venting unit. For a solar powered unit you will need to shell out another $1000.
