Skylight Installation Cost Guide

At the most basic level, a skylight is simply a window that is placed on the ceiling rather than the wall. It allows sunlight to penetrate a space, and it can add a bright, airy and spacious feel to an otherwise ordinary room. Skylights can even reduce heating costs by allowing natural sunlight to heat the surrounding space. They also have the potential to increase the overall value of your home, but they will be a significant investment. Since installing skylights is not a job that the average homeowner can tackle, you may need to bring in a professional to cut through the roof and place a skylight of your choosing. Use this guide to get a better understanding of the types of skylights available as well as how much installation might cost.

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.

Choosing Between the Three Major Skylight Options

When gearing up for skylight installation, it is important to have a basic understanding of the three major options on the market. The type you choose can affect the style of your home as well as your budget, so doing a little research beforehand is a smart idea. As the name suggests, fixed skylights don't move or open. These are the most common skylights available, and they are also typically the cheapest. Tubular skylights are also quite affordable, and they are circular and very similar to portholes on a ship. The most expensive option is ventilating skylights, which can open, let in a fresh breeze and even be operated by a remote control.

Selecting Glass Type, Efficiency and Noise Control

Just like when you purchase ordinary windows, you should always pay attention to the kind of glass used in the skylights. The cheapest options are not always best, and they can reduce the insulation in the room, raise your energy costs over time or even create a noisy environment if you happen to live near a school or a busy road. You may want to invest in double-paned or even triple-paned windows to provide extra sound and heating insulation in your home.

The size of your skylights, the height of your roof and the number of skylights you want installed at one time can also influence the total cost of professional installation.
