"They were able to replace the skylight in less than 2 weeks after the quote. They did a good job and make the finish on the inside look good. A few weeks later, there was a heavy rain and my new skylight is no longer leaking like my old one that was replaced."

"We had a roof leak caused by an incorrectly installed skylight. Sami called me in less than a half-hour after my inquiry. He arrived within an hour, inspected the skylight and adjacent roof tiles, and gave me a detailed, very fair, written estimate to resolve the problem. A few days later, Sami and his assistant arrived, fixed the problem and gave us a four year warranty on the repair. Prompt, polite, skilled and honest are appropriate descriptors for Pro Experts of Long Island. Highly recommended without any reservations whatsoever!! GJC, Bay Shore, NY 11706"

Skylights FAQs, answered by experts

The decision to remove a skylight depends on your specific circumstances and preferences. There are several reasons why you might consider removing a skylight, such as extensive damage, a desire for better insulation, or the need to change the room's layout. Additionally, if the skylight is causing leaks or other issues, it may be necessary to remove and replace it (which can incur additional skylight installation costs). It's important to assess your specific situation and consult with professionals if needed to make an informed decision.

In most cases, installing skylights will add value to your home, making them a worthwhile investment for many homeowners. Buyers are often attracted to the aesthetic appeal of skylights, as they make rooms feel brighter, airier, and more spacious by introducing natural light without compromising privacy. Beyond aesthetics, skylights can offer monetary benefits by potentially reducing energy bills. Additionally, models that can be opened provide extra ventilation, which is particularly useful in hotter climates for allowing accumulated hot air to escape from the ceiling. However, the return on investment depends on several factors. To maximize value, it's crucial that the skylights are installed by an experienced professional to avoid risks like water damage, which can deter savvy buyers. Regular maintenance and cleaning are also important. Furthermore, choosing the right frame and glazing materials for your specific climate will enhance their performance and appeal. While skylights are generally seen as an asset, homeowners should also consider the initial cost, which averages around $1,500 for installation.

Skylights are the most likely windows to leak if installed improperly, so there are a few questions you should ask any skylight installer before you hire them:

  • Do you specialize in skylight installation or only windows in general?

  • Do you offer any kind of warranty for the installation?

  • What recourse do I have if the skylight leaks shortly after installation?

  • Do you have references I can speak with?

  • How long have you been in business?

  • Are you licensed and insured?

To maintain a skylight and ensure its performance over time, regular maintenance is required. This includes periodically cleaning the glass and frame to remove dirt, debris, and condensation. It is also crucial to inspect the seals and flashing at least once a year for any signs of wear, degradation, or leaks, paying special attention after heavy storms. Ensure that the drainage system is clear to prevent water buildup and potential leaks. Address minor issues like cracks promptly and consider occasional resealing to prevent drafts and moisture problems. While energy-efficient skylights with Low-E coatings or double glazing may require less upkeep, periodic professional servicing can help keep any skylight in optimal condition.

Fixed skylights are by far the most popular type. Because skylights can be pretty high up on your ceiling, fixed (rather than operable) skylights remove some maintenance from the equation. Plus, you don’t have to constantly worry if you shut your skylight fully the last time you opened it or if you’re going to find a leak later on during a rainy day.
