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.
01
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.
02
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.
03
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.
04
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.
05
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.

The process was smooth and Howard did all the heavy lifting with insurance company. All the work and final billings were exactly as described by Howard, no surprises. Thanks again!Posted on Google Eli M. GalaydaTrustindex verifies that the original source of the review is Google. We worked with Howard B. from Aegis during a home insurance claim, and I’m very glad we did. From the beginning, Howard was patient, steady, and extremely thorough. He took the time to understand the full scope of the damage, walked us through what to expect, and never rushed the process just to move things along. He was present on site when work was being done... always making sure nothing was missed and that the details were documented correctly. What I appreciated most was how he stayed involved throughout the entire claim. Howard handled communication with the insurance company directly and consistently. Whenever there were questions or pushback, he responded with clear documentation and evidence... not opinions or assumptions. That made a huge difference in keeping things accurate and complete. He was also very responsive and easy to work with... always available to explain what was happening and why (even with questions that came after everything was paid). Highly recommend the Howard + Aegis combo.Posted on Google Mackenzie DrosdTrustindex verifies that the original source of the review is Google. Aegis recently completed some repairs on our roof.
