A skylight installation in Chicago, IL, runs $2,500 on average, and ranges from $1,344 to $3,839. Your total price depends on the skylight's size, your roof's slope, and local labor rates. Before adding natural light to your home, understanding the cost helps you plan a project that fits your budget.

Skylight Installation Cost Factors

When planning a project in Chicago, IL, hiring a local skylight installer ensures your new fixture can withstand the region's harsh weather. Several variables influence the final price, from the style of the window to the complexity of the roof modifications.

Type of Skylight

The design and functionality of your window heavily dictate the overall price of the project. Most homeowners spend between $1,344 and $3,839 in total, but the specific style you choose determines where you fall in that range. In Chicago, IL, fixed models are popular for keeping out the frigid, windy winter drafts, running $1,250 to $2,490 per unit. If you want a unique shape to match your home's architecture, custom units are the most expensive option, starting around $2,590 to $5,700+ per window. Before selecting a model, we recommend scheduling a roof inspection to ensure your structure can support the new addition.

Skylight Size

The physical dimensions of the window directly impact the amount of materials and labor required, which drives up the total expense. Larger openings mean more structural modifications and a higher overall $2,500 average for the project. For compact spaces like hallways, 10- to 14-inch tubular models range from $935 to $1,660 per installation. Conversely, oversized 48- to 72-inch units cost between $2,590 to $5,180+ per installation because they require extensive framing. When installing larger units in Chicago, IL, contractors must ensure the surrounding framework can handle heavy snow loads during winter blizzards. While the ceiling is open, we recommend checking your attic insulation cost to see if upgrading your thermal barrier makes sense.

Demolition and Prep

Preparing the roof and ceiling involves cutting through existing materials and reinforcing the structure, which adds significant labor time to the job. If you are retrofitting an older home in Chicago, IL, the crew must carefully remove shingles and underlayment to ensure a watertight seal that withstands severe thunderstorms and spring flooding. Extensive preparation work increases the total project price, pushing it closer to the $6,000 maximum. Once the new unit is securely in place, you must factor in drywall repair costs to seamlessly blend the interior ceiling around the new opening.

Skylight Installation Pro Costs

Hiring a professional in Chicago, IL, ensures your new window is properly sealed against severe thunderstorms and blizzards. Local contractors charge per unit rather than hourly for this work. For example, installing a standard fixed skylight runs $1,250 to $2,490 per unit, while complex custom models cost $2,590 to $5,700 per unit. When budgeting for your project in Chicago, IL, remember to factor in the local 10.25% sales tax on the materials your pro purchases.

Licensing

Before hiring a skylight installer, verify they hold the required skylight installation license for Illinois or Chicago, and ask for proof of liability insurance and workers' comp if they have employees. Hiring an unlicensed skylight installer can leave you with little protection if something goes wrong and may make it harder to recover payments or hold them accountable. To verify the type of licensing required, visit the Illinois government's official licensing board website for more information.

Permits

Before starting skylight installation, confirm whether your project requires permits in your area and who is responsible for obtaining them. Permit requirements and costs vary by location, but most skylight installation permits range from $50 to $400, depending on the scope of work and your local municipality. Working without the proper permits can lead to fines, project delays, or complications when selling your home. If you're hiring a skylight installer, review your contract to ensure they will handle the permitting process and inspections. To verify permit requirements, visit your city or county's official building department website for the most accurate and up-to-date information.
