We work closely with homeowners and general contractors to install high-quality windows that align with your design vision while meeting all structural, energy, and Chicago building code requirements.

Energy-Efficient Windows

Chicago’s long heating season makes window thermal performance one of the highest-return upgrades a homeowner can make. Our energy-efficient window options are specifically selected to minimize heat loss through brutal Midwest winters and keep your home cooler through summer, delivering measurable reductions in monthly utility costs without sacrificing comfort or aesthetics.

Custom Window Solutions

Every home has its own character, and Chicago’s older housing stock demands it. We offer fully customized window solutions in a wide selection of sizes, styles, materials, and finishes. Whether you are matching original profiles on a vintage bungalow, installing a specialty-shaped window in a greystone, or creating a standout architectural feature, we will help you achieve the right fit for your home.

Emergency Window Repair Services

A broken or severely damaged window in a Chicago winter is not a situation that can wait. Our team responds promptly to emergency window situations, providing fast assessment and replacement to restore your home’s security, weatherproofing, and energy performance as quickly as possible.

Signs Your Chicago Home Needs Window Replacement

The difference between catching window problems early and catching them late is often the difference between a window replacement and a window replacement plus framing repair. Here is what to watch for on your Chicago home.

Drafts Near Closed Windows: Feeling cold air movement near fully closed windows signals failed weatherstripping, damaged seals, or frame gaps that have widened through freeze-thaw cycling. In a Chicago winter, this is a measurable, ongoing energy loss with every heating cycle.
Condensation Between Glass Panes: Moisture visible between the panes of a double or triple-glazed window means the insulating gas seal has permanently failed. The window is no longer performing at its rated thermal efficiency and cannot be restored without full replacement.
Visible Rot, Warping, or Frame Damage Deteriorating frames signal moisture intrusion that has likely extended into surrounding framing. This requires an assessment of the rough opening before replacement, not just a new window unit dropped into a damaged opening.
Windows That Do Not Operate Properly: Windows that stick, refuse to open, or do not lock securely create both safety and security vulnerabilities. Neither issue resolves on its own.
Significant Noise Penetration: Modern double and triple-glazed windows provide substantially better sound attenuation than older single-pane or early double-pane units. If traffic, neighborhood noise, or nearby transit lines are clearly audible through closed windows, upgraded glazing will make a noticeable difference in day-to-day comfort.
Age of 20 or More Years: Windows installed two decades ago are operating with glazing technology, weatherstripping, and seal materials a generation behind current standards. Even windows that appear functional are likely underperforming significantly on thermal efficiency compared to what a modern replacement delivers.

Types of Windows We Install in the Chicagoland Area

Aegis installs all major residential window styles for homes throughout Chicago and the Chicagoland area. Our team helps you select the right style for each room based on function, ventilation needs, architectural character, and your home’s existing exterior profile.

Double-Hung Windows

The most widely installed window style in Chicago residential homes. Both sashes slide vertically, providing ventilation from the top, bottom, or both simultaneously. Easy to clean from inside the home, compatible with virtually every architectural style from vintage bungalows to contemporary builds, and available in a full range of sizes and materials. The practical standard for most Chicago rooms.

Casement Windows

Hinged on the side and opening outward with a crank mechanism, casement windows create a complete weathertight seal when closed that makes them among the most energy-efficient styles available. Particularly effective on the windward sides of Chicago homes where a tight seal against lake-effect weather and winter wind infiltration matters most.

Sliding Windows

Opening horizontally rather than vertically, sliding windows are a practical choice for rooms where a projecting sash is not desirable, including above counters, walkways, or tight exterior clearances. A common choice for kitchen windows and lower-level rooms throughout Chicago and the suburbs.

Bay and Bow Windows

Extending outward from the exterior wall, bay and bow windows add architectural dimension, create additional interior space, and bring in significantly more natural light than standard flush windows. A defining feature on many classic Chicago bungalows and two-flats. Bay windows feature a central picture unit flanked by operable casement or double-hung units. Bow windows use a curved arrangement of four or more units for a softer profile.

Picture and Specialty Windows

Fixed windows that do not open, designed to frame views and flood interior spaces with natural light. Because they have no moving parts or operational hardware, picture windows maintain a tighter seal than operable windows and deliver excellent energy efficiency. Aegis also installs custom-shaped specialty windows including arched, transom, and non-standard configurations that match the original character of vintage Chicago properties.

Our Window Installation Process

At Aegis, we follow a proven, detail-oriented window installation process to ensure every project is completed with precision and care. From the initial consultation to the final inspection, our goal is to deliver a seamless experience and long-lasting results for your home.

Free Consultation & Assessment

We begin with a no-obligation assessment of your existing windows, rough openings, and surrounding wall assembly. You receive an honest evaluation of each window’s condition and a clear recommendation before any decisions are made.

Window Selection and Transparent Estimate

We guide you through style, material, and glazing options based on your home’s architecture, performance priorities, and budget. You receive a detailed written estimate before any work begins. Every line item is explained, no hidden costs.

Precise Measurement and Order

Every window is measured to the exact dimensions of your rough opening before ordering. Precision here prevents the air gaps, shimming problems, and performance issues that result from imprecise measurement.

Professional Removal and Installation

Our licensed, insured team removes existing windows, addresses any framing or moisture barrier issues in the rough opening, and installs new windows with proper flashing, sill pan, air sealing, and trim throughout.

Final Inspection and Walkthrough

We inspect every installed window for operation, seals, trim, and weathertightness before we leave. Your project is not closed until you have reviewed the work and are fully satisfied.

Why Chicago Homeowners Choose Aegis for Window Installation

When it comes to upgrading your home’s windows, it is important to choose a contractor you can trust to provide high quality installation. At Aegis, we combine experience, quality materials, and customer-first service to deliver exceptional results.

Full Exterior Contractor Advantage: Aegis installs windows, roofing, siding, and gutters. When your window replacement is part of a broader exterior update, or when existing windows have caused damage to surrounding siding or trim, we address the complete picture. A window-only contractor cannot do that.
We Assess the Rough Opening Before Installing: Most window installation problems originate not in the window itself but in what was behind the old one. Aegis inspects and addresses framing and moisture barrier conditions before new windows go in. That step is what separates a 30-year installation from one that starts failing at year seven.
Fully Licensed, Bonded, and Insured: IL License #104.017330. Every project is completed by qualified professionals meeting all Illinois licensing and insurance requirements.
10-Year Workmanship Warranty: Every window installation is backed by our 10-year workmanship warranty. If something goes wrong with our work, we come back and fix it.
Transparent Pricing, No Pressure: Written estimate before work begins. No manufactured urgency, no hidden costs, no scope changes without your approval.
Chicago Housing Stock Experience: Vintage bungalows, two-flats, greystones, newer suburban construction, and everything in between. We understand the non-standard opening sizes, original trim profiles, and framing conditions of Chicago’s older homes and work with them accurately.
BBB Complaint-Free Award Recipient: Recognized by the Better Business Bureau for consistent, trustworthy service throughout Chicagoland.

Frequently Asked Questions - Window Installation

How long do residential windows last?

Most residential windows last between 15 to 30 years, depending on the material, installation quality, and maintenance. Vinyl and fiberglass windows tend to last longer with minimal upkeep, while wood windows may require more maintenance but can also have a long lifespan when properly cared for.

What’s the difference between window replacement and repair?

Window repair addresses specific issues like broken glass, damaged seals, or hardware problems, helping extend the life of your existing windows. Window replacement, on the other hand, involves removing the entire window unit and installing a new one, typically recommended when windows are old, inefficient, or extensively damaged.

Are energy-efficient windows worth it?

Yes, energy-efficient windows are a smart investment. They help reduce heat loss in the winter and keep your home cooler in the summer, which can lead to lower energy bills and improved indoor comfort. Over time, the savings and added value to your home often outweigh the initial cost.

How much does window installation cost in the Chicago suburbs?

The cost of window installation varies based on factors like window type, size, materials, and the number of windows being installed. On average, homeowners in the Chicago suburbs can expect to pay anywhere from $300 to $1,200+ per window, including installation. Aegis provides free estimates to give you accurate pricing based on your specific project.

How long does installation take?

Most standard window installations take about 30 minutes to an hour per window. A full-home window replacement can often be completed in one to two days, depending on the size of the project and the number of windows. Our team works efficiently while ensuring every installation meets our high standards of quality.

 Trustindex verifies that the original source of the review is Google. After hail damage hit our roof, we called Aegis Construction, it turned out to be one of the smoother home repair experiences we've had, and that's saying something when insurance is involved. Our rep, Zach Greenberger, walked us through every step of the claims process and was always available when we had questions. They had a huge selection of high quality materials to choose from, showed up exactly when they said they would, and the crew did beautiful, clean work from start to finish. They even managed to sneak in a few upgrades to the house while still keeping everything within what our insurance covered. Aegis actually has a real facilities and offices, right here in Elmhurst and Villa Park, so you know they're not disappearing after a storm rolls through. Highly recommend them for any roofing or gutter work, hail damage or any other exterior projects you might have.

 Trustindex verifies that the original source of the review is Google. From the very first phone call, my experience with Aegis Construction Group, Inc. has been exceptional. A few months ago, Mike came out to inspect my roof, and I was incredibly impressed with how thorough, honest, and professional he was. He took the time to carefully inspect everything and reassured me that my roof was in great shape. I truly appreciated that he wasn’t trying to sell me something I didn’t need. Unfortunately, our area has been hit hard with several severe storms since then, including another one after Mike’s inspection. I called Jake, the manager, to share my concerns, and without hesitation, he immediately arranged for someone to come back out and inspect my roof again just to make sure no new damage had occurred. That level of customer service is hard to find. The entire team genuinely cares about homeowners and goes above and beyond to provide honest advice, peace of mind, and outstanding service. It’s easy to see why Aegis Construction Group has so many glowing reviews, they’ve certainly earned them. If you’re looking for a trustworthy, knowledgeable, and responsive roofing company, I can’t recommend Aegis Construction Group, Inc. enough. Thank you to Mike, Jake, and the entire team for your professionalism, integrity, and exceptional customer care!

 Trustindex verifies that the original source of the review is Google. After many attempts on finding a roofing company, Aegis was the only one to respond to my calls. Not only did they respond, but they did responded right away! I forgot who I talked to first but he was very responsive to me even during a difficult time he was going through. From there he sent over one of his guys to help me. I was helped by Bryan. He always kept in touch with me on what the plan was. He was on top of it. He also explained how some insurance companies worked and guided me throughout the whole process. While we were waiting for the shingles to arrive, they tarped the area of the roof that was damaged. I forgot who worked on my roof but he was done within an hour or so. Granted, it was a few shingles that had to be replaced. They also noticed my front siding was missing a piece and offered to fix it up as well. Amazing work and customer service from all the guys here.

 Trustindex verifies that the original source of the review is Google. I’ve been involved with public project management for 40 years, and my experience with Aegis Construction Group (for my personal home roof and gutter replacement caused by hail damage) by far is one of the best contractor’s, especially Nico Buccieri, that I’ve worked with that included but not limited to: initial roof inspection, acceptance of Owner requested contractual terms & conditions, worker safety (OSHA compliance), contract administration/documentation (addendums, owner initiated change orders, waiver of liens, invoices, etc), insurance administration/cost negotiations, ethical, subcontractor management, material options, overall client communication,  quality of workmanship and fair pricing. Based on my specific experience I would consider rehiring Aegis for any future work.

 Trustindex verifies that the original source of the review is Google. After a bad August storm we had our roof replaced. Howard from Aegis walked us through the insurance claims process and was in constant contact. Great guy to work with and enjoyable to talk to.  Moshi was great as well.  They both made the whole process seamless. Very glad I went with Aegis and I highly recommend them!

 Trustindex verifies that the original source of the review is Google. Aegis replaced my roof, soffits, gutters and downspouts.  The quality of work,  quality of products used, their amazing construction crews, the clean up, the finished product and communication during the construction was so much better than l anticipated.  If possible l would give them more than 5 stars.

 Trustindex verifies that the original source of the review is Google. If you need your roof done, go with Carmen Curio (with Aegis Construction Group ) .  He has my highest recommendation. He has been diligently working through my situation with me since October(!), helping me through each phase of the process.  I don't want to go into too much detail here, but it all began when he alerted me to some red flags that were so disheartening at the time, but really ended up saving me a LOT of money and hassles in the long run.  Every time I text him, he replies promptly and never gives the impression that I'm annoying him...even though my friends all know how annoying I actually am. The roof is done, but the insurance process is not...and he is still going the extra mile to help me through it (even though Aegis Construction has been paid and Carmen has nothing really left to gain financially).  I feel like most people/companies in the same position just move on to the next paycheck, providing the "extra mile" only to secure the job.  This, in and of itself, speaks volumes about him and Aegis.  They are the real deal.  Thank you, Carmen.  I know I'm not your friend, but you're a friend.

 Trustindex verifies that the original source of the review is Google. I feel your new website is most impressive, covering all questions a perspective buyer would be thinking. When mentioning siding, towns are mentioned...then it is stated plus...."surrounding towns ". What would those towns be? Might become a make or break it for customer.

 Trustindex verifies that the original source of the review is Google. 100% recommend Aegis!! We had hail damage to our roof right before an out-of-state move, and gave Aegis a call to help us out.  Kenny and Rae handled all the back and forth with insurance, worked hard to get us a fair adjustment, and provided us photos and updates along the way.  The work was done very promptly, and they made a very stressful situation as smooth as could be.
