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.
Average Cost of Professional Skylight Installation. Before you start dreaming of a stunning skylight that lets sun into your home, it is important to have a rough estimate of the costs involved. Since every house or apartment is constructed differently, no two projects will be the same or incur the same expenses. However, you should expect that professional skylight installation will cost roughly $1,812, which is the national average. The most inexpensive projects can come in as low as $700, and the largest and most involved skylight installation may be as much as $3,500.
