Providing customized, energy-efficient Window Replacements

Replacing your windows is more than a cosmetic upgrade. For Fort Collins homeowners, it can mean lower energy bills, quieter interiors, and a more comfortable home year-round. At Custom Exteriors, we make the process simple from start to finish. Our team begins with a free consultation to evaluate your current windows and discuss replacement options. Next, you’ll receive a detailed estimate with clear pricing and no surprises. During installation, our professional crews remove your old windows, fit new ones to manufacturer specifications, and leave your space clean and protected. Finally, we perform a comprehensive inspection to confirm your windows operate perfectly and your home is sealed for efficiency. Whether you’re replacing one window or updating your entire home, our installers work quickly, carefully, and with respect for your property.

Fort Collins experiences strong sun, cold winters, and constant temperature swings. That’s why we install ENERGY STAR®-rated windows built for Colorado conditions. Our energy-efficient options feature advanced components such as double- or triple-pane glass, Low-E coatings to block UV and heat, argon gas insulation, and durable vinyl, fiberglass, or composite frames. We’ll help you select windows that match your home’s design and energy goals, from traditional double-hung styles to casement, slider, bay, and picture windows.

Local homeowners choose Custom Exteriors because we’re more than a window contractor; we’re part of the Northern Colorado community.

Did You Know?

Did you know that window replacements can significantly impact your energy bills? It’s a little-known fact that old, inefficient windows can contribute to heat loss and air leakage, leading to higher heating and cooling costs.

Replacing your windows with energy-efficient options can improve your home’s insulation and reduce energy waste. Modern windows are designed with advanced technologies like double or triple glazing, low-emissivity coatings, and insulating gas fills, which help to keep the heat in during winter and block out the heat during summer. This translates to lower energy consumption and, ultimately, savings on your utility bills.

Additionally, new windows often come with improved sealing mechanisms that prevent drafts and air leakage. This enhances your comfort by reducing cold spots and drafts and helps maintain a consistent indoor temperature throughout the year.

So, if you’ve been on the fence about window replacements, consider the hidden benefits they offer. By upgrading to energy-efficient windows, you can not only enhance the beauty and functionality of your home but also save money on your energy bills in the long run. It’s a wise investment that pays off both comfort and cost savings.

Exploring window Styles:
finding the perfect match for your home

When it comes to windows, there are many styles to choose from. Each one comes with its own purpose and look. So, if you are considering new windows, it’s important to understand the different styles you can choose from. Here are a few of the options for your Fort Collins window replacement: 

Custom Exteriors installs double-hung windows replacements as a Fort Collins window replacement company

Double-Hung Windows:

Double-hung windows have a window sash on the top and the bottom that can move. This means you can open the window from the top or the bottom. They are great for ventilation and easy to clean. 

Custom Exteriors installs single-hung windows replacements as a Fort Collins window replacement company

Single-Hung Windows:

Single-hung windows look similar to their double-hung counterparts on the surface. However, rather than opening from the top and the bottom, only the bottom is operable, leaving the top fixed. 

Custom Exteriors installs sliding windows replacements as a Fort Collins window replacement company

Slider Windows:

Slider windows slide back and forth, similar to a sliding glass door. They are easy to use and let in a good amount of light. They are great for smaller areas where a swinging window couldn’t fit. 

Custom Exteriors installs awning windows replacements as a Fort Collins window replacement company

Awning Windows:

Awning windows open from the bottom and swing out from the top. They’re called “awning” because they resemble an awning when open. This design allows them to remain open during light rain.

Custom Exteriors installs bay windows replacements as a Fort Collins window replacement company

Bay and Bow Windows:

These windows stick out from your wall. Bay windows have three parts, while bow windows often have many more. They make the room larger by creating additional interior space.
