Installing a Door With Sidelights: What Homeowners Should Know
A door with sidelights can dramatically elevate your home’s exterior while bringing more natural light into the entryway. Whether you choose a single sidelight, double sidelights, or add a transom above the door, this type of entry system creates a more open, welcoming, and upscale appearance.
Here’s a quick look at common configurations:
| Configuration | Typical Use |
|---|---|
| Door + single sidelight | Great for adding light with a more compact footprint |
| Door + two sidelights | Creates a balanced, grand front entry |
| Door + sidelights + transom | Maximizes natural light and architectural impact |
Popular material options:
- Steel Strong, secure, and sleek
- Fiberglass Durable, energy-efficient, and low maintenance
- Wood Rich, timeless beauty with a custom look
Adding sidelights transforms a standard entry door into a statement feature. Because these systems involve more framing, glass, sealing, and detailed finish work than a basic door replacement, choosing the right installer is just as important as selecting the right product.
Your front door is one of the first things guests and potential buyers notice about your home. A door with sidelights doesn’t just make a strong impression. It also improves natural light, enhances curb appeal, and reflects the craftsmanship and quality of the home itself.
I’m Voytek Glab, owner of Perfect Windows & Siding, and over the past 20+ years installing entry doors across the Chicagoland area, I’ve helped hundreds of homeowners choose the right door-with-sidelights solution for their homes from material selection to final trim work. In this guide, I’ll walk you through the key factors that shape the project so you can plan with confidence.
Factors Influencing the Value of Installing a Door With Sidelights
When we look at a project involving a new entry system, we aren’t just looking at a slab of wood or metal. We are looking at a complex structural component of your home. Several variables determine the scope, performance, and long-term value of the project.
One of the primary drivers is the condition of your existing frame. If we find wood rot or structural instability in the “rough opening,” those repairs must happen before the new door goes in. According to Project Spending Data: Harvard University JCHS Homeowner Expenditures, homeowners are increasingly investing in high-quality exterior upgrades to ensure long-term durability.
Structural modifications also play a role. If you are replacing a standard 36-inch door with a door plus two sidelights, we have to widen the opening. This involves cutting into the wall, potentially moving electrical wires, and installing a new “header” to support the weight of the house above the wider gap. For more details on the process, you can explore our guide on exterior door installation.
Material Quality and Long-Term Value
The material you choose is perhaps the biggest factor in how your new entry system performs over time. In the Chicago climatewhere we swing from humid summers to sub-zero wintersmaterial choice isn’t just about looks; it’s about durability, insulation, and reliability.
- Fiberglass: This is often our top recommendation. Fiberglass mimics the look of real wood but won’t warp, rot, or crack. It offers excellent insulation and long-lasting durability.
- Steel: A strong, secure option that provides dependable performance and a clean, modern appearance, though it can be prone to dents or scratches over time.
- Solid Wood: The gold standard for aesthetics. Wood offers a high-end, custom feel but requires regular maintenance (staining or painting) to protect it from the elements.
The Department of Energy research on energy-efficient exterior doors highlights that choosing the right material can significantly impact your home’s thermal retention. For those looking for something truly unique, we offer custom entry doors in Chicago tailored to your home’s specific architectural style.
Structural Requirements and Installation Complexity
Installing a door with sidelights is significantly more labor-intensive than a standard swap. We have to ensure the subfloor is perfectly levelif it isn’t, a wide unit with sidelights will never sit correctly, leading to drafts or sticking doors.
In many older homes in areas like Park Ridge or Evanston, the rough opening isn’t a standard size. This requires “rough opening adjustments,” where we rebuild the framing to fit the new pre-hung unit. Because these units are heavy and wide, the header (the horizontal beam above the door) must be rated to handle the load. You can learn more about how we handle these complexities in our entry door installation in Chicago overview.
The Importance of Professional Labor and Craftsmanship
You could buy the most expensive door in the world, but if it’s installed poorly, it will perform poorly. Professional installation is essential, especially when you’re dealing with a larger entry system that includes sidelights and custom framing.
We focus on precision. A door with sidelights has more “seams” than a standard door, which means more opportunities for air to leak in. Our team ensures that every hinge is mortised perfectly and every weatherstrip is compressed just right. Data from the Occupational Employment and Wage Statistics for Specialty Trades shows that skilled carpentry is a specialized field for a reasonit requires years of experience to master the geometry of a house that may have settled over decades. If you’re looking for front entry doors with sidelights installation near me, you want a team that understands these nuances.
Precision Sealing and Insulation
In Chicagoland, insulation is everything. When we install a door with sidelights, we use high-grade sealants and expanding foam insulation that meets or exceeds Energy Star standards.
The glass in your sidelights shouldn’t be a weak point for heat loss. We utilize Low-E (low-emissivity) glass which has a microscopic coating that reflects heat back into your home in the winter and keeps it out in the summer. We also ensure thermal breaks are present in the door sills to prevent the cold from “bridging” from the outside metal to your inside floors. This attention to detail is standard for our residential custom entry doors.
Enhancing Curb Appeal with Custom Features and Transoms
If you want to take your “Grand Entrance” to the next level, a transom windowthe glass pane that sits above the dooris the way to do it. This configuration adds even more natural light and architectural character to your entryway.
Beyond just adding glass, you can customize the privacy and style of your entry:
- Privacy Glass: Options like frosted, seeded, or rain glass allow light in while keeping prying eyes out.
- Decorative Grilles: These can match the window patterns of your home (like Colonial or Prairie styles).
- Hardware: From aged bronze to satin nickel, the “jewelry” of your door matters. Smart locks are also a popular integration for modern security.
Single vs. Double Sidelight Comparison
| Feature | Single Sidelight | Double Sidelights |
|---|---|---|
| Visual Impact | Asymmetrical, modern | Traditional, grand, balanced |
| Light Intake | Moderate | Maximum |
| Space Required | 42″ – 50″ wide | 52″ – 72″ wide |
| Labor Complexity | Standard structural work | High (often requires new header) |
Regional Considerations for Chicago Area Homeowners
Living in the Chicago suburbs means your door has to be “tougher” than a door in Georgia or California. In Des Plaines, we see many traditional ranch and colonial homes where a wood-grain fiberglass door with dual sidelights adds incredible value. In Park Ridge, building codes can be specific regarding “egress” and structural changes, which is why we handle all the necessary paperwork for you.
Our installations in Morton Grove and Skokie often focus on high weather resistance. We use specialized flashing techniques to ensure that driving rain and melting snow never penetrate the threshold. For more on how we adapt to local needs, see our page on exterior door installation in Chicago.
Frequently Asked Questions about Door Installations
How long does it take to install an entry door with sidelights?
A standard replacement usually takes between 3 and 8 hours. If we are widening the opening or installing a unit with a transom, it can take a full day or sometimes a bit longer if significant structural framing is required. We always aim to have your home “dried in” and secure by the time we leave on day one.
Is a permit required for altering a door opening in Chicago?
Yes, in most Chicagoland municipalities, if you are changing the size of the opening (like moving from a single door to a door with sidelights), a permit is required. This ensures the new header is structurally sound and the work meets local safety codes. We handle the permit process for our customers to make it as stress-free as possible.
What are the benefits of fiberglass over wood for sidelight doors?
While wood is beautiful, fiberglass is the “workhorse” of the Midwest. It offers up to four times the insulating R-value of wood, it won’t rot when exposed to snow piles, and it requires almost zero maintenance. For a door system with sidelights—which has many joints and glass seals—the stability of fiberglass is a huge advantage in preventing leaks over time.
