Old windows that stick, have a worn appearance, or have condensation between panes should be replaced. This helps improve home insulation, and it increases energy efficiency, since indoor temperatures remain more consistent. Window Concepts offers window replacements for homes throughout the Chicago suburbs. Here is some information that homeowners need to know about new windows and how they increase home value:

Energy Efficiency

Modern window replacements help improve a home’s energy efficiency. Older windows that aren’t properly sealed or installed often cause drafts, forcing the home’s heating and cooling systems to run more frequently. This uses more energy over time, and it can increase homeowners’ monthly energy bills. Window replacement allows for tighter seals that prevent drafts. 

Single-pane glass should be replaced with modern, multi-pane insulated windows. Multiple panes are separated by gas, and this helps reduce heat transfer between indoor and outdoor environments. When the home stays warm or cool longer, the HVAC system cycles less frequently. Tilt-and-turn windows and double-hung windows utilize argon gas. Argon slows heat transfer more effectively than air, which improves the window’s insulating performance.

Some older houses also have aluminum-framed windows, which conduct heat more readily. This lets more heat pass through the window frame, and it reduces the window’s overall insulating performance. Advanced, precision-crafted frames resist heat conduction and stop air from passing through them. This design supports a more consistent indoor temperature. Properly sealed frames also prevent drafts by limiting air leakage around the window perimeter. Window Concepts addresses these sources of heat loss with replacement windows that use airtight frames and modern glass. We also offer free, in-home draft and energy assessments to evaluate existing windows and determine where improvements may be needed.

Ventilation and Moisture Protection

Chicagoland experiences high moisture levels, periodic storms, and hard freezes throughout the year. Replacing windows helps improve home ventilation and increase airflow while preventing moisture and mold, which can negatively affect home value. Some window styles are also designed to direct water away from the home. These include: 

• Hopper windows: These open inward, making them practical for basement areas and other spaces with limited room.
• Awning windows: These use a hinge and open up and outward; raindrops run down the tilted window and do not enter the home. This allows homeowners to safely open them during rainfall to increase fresh air in the home.
• Casement windows: Casement windows have hinges along the side and utilize crank handles, allowing them to open like a door. This style works well in larger spaces, allows more airflow when open, and provides a view of the outdoors.
• Double-hung windows: This style allows homeowners to control how much air enters the home. The two independent sashes let residents open one partway or both to increase ventilation. 

Modern windows with properly sealed frames help prevent water from entering around the window, offering additional protection against Midwest spring rains. During window replacement, technicians flash windows to prevent moisture from entering. Proper flashing also helps protect the wall assembly around the opening from water damage over time.

Long Lifespan

Professional window contractors can provide access to replacement windows made with higher-quality materials and components. High-quality materials help prevent early damage such as cracking, warping, or fading. Cracked windows let moisture into a home, while faded frames make the exterior look worn and reduce curb appeal. Quality materials help extend the lifespan of the windows, preventing early or frequent replacement. 

When selecting a window replacement company, look for technicians who follow correct installation methods. This includes completing an assessment in advance. Installers inspect the window frame around the rough opening to see if it is soft or crumbling. If it is, they replace it before installing a new window. They also make sure the flashing extends over the opening sill and integrates with the drainage plane. This helps prevent water from entering the framing cavity, which can result in rot; adequate flashing confirms water drains outward instead.

Sealing the space around the window also requires materials that accommodate temperature changes. Backer rods help control the depth of the sealant joint, so the sealant can flex as the frame expands and contracts. This is beneficial in Chicago basements, where heated interior spaces differ from temperatures around exterior window wells. Professional installers make sure they choose a sealant that accounts for these temperature changes. By completing a project assessment in advance, our team confirms window measurements and conditions so windows remain tightly sealed across their lifespan. 

Egress Windows

Replacing or installing egress windows helps promote overall safety and keeps the home aligned with building codes. Egress windows serve as safety exit routes, so their dimensions must meet the International Resident Code’s guidelines for minimum opening size. Finished basements and attics used as living areas must meet egress standards. Casement, sliding, or hopper windows can function as egress windows. Meeting egress requirements supports home value by making finished basement and attic spaces more functional and marketable to prospective buyers.

Curb Appeal

Replacing windows helps increase home value by updating and improving the overall appearance of the home. New designs create visual interest, and homeowners are able to choose windows that better complement the home’s style. For traditional or modern styles, homeowners can utilize double-hung windows. These offer a classic, versatile design. Modern or minimalist homes typically benefit from casement windows, which feature slimmer frames. Sliding windows are beneficial for contemporary spaces because they provide wider openings. New windows also increase visual appeal inside the home and the amount of natural light in the space. 

When replacing or adding windows, homeowners can choose a style that suits the space and provides the functionality they need. Some customization options include: 

• Unique shapes: Homeowners can design custom shapes and styles for their windows to create focal points for unique architecture. Specialty window options include arches, circles, angles, and other shapes; these emphasize a home’s style. 
• Specialty panes: Homeowners may select low-e glass panes, which use clear metal layers that block UV rays. Reducing UV rays helps protect furniture and other items in the home from sun damage. The clear layers still allow natural light to enter the house.
• Custom sizes: Customization provides solutions for spaces that do not have standard window openings, helping improve ventilation in tight or enclosed spaces. Homeowners are able to choose window styles that work well in smaller rooms or spaces with limited access. Some designs also make routine maintenance easier by allowing the window to be opened, cleaned, or operated from inside the home. 
• Dimensional designs: Bay windows feature three panels and are extended from the home, and bow windows have four panes. These add dimension to a flat wall, and they provide different angles for viewing the outside.
