    The Advantages of Upgrading the Windows of Your Fort Collins Home

    Window replacement can be a great upgrade for almost any home in the Fort Collins area, but especially for those that have single-pane, wood, or aluminum windows. Older windows can be drafty, ill-fitting, and poorly sealed, leading to high energy bills and discomfort in your home.

    At Lomax Window & Door Co, our window installers strive to help our customers increase the efficiency and comfort of their homes. We offer a wide range of replacement window options, from energy-efficient options to windows that are designed to enhance the aesthetic of your home. With our professional installation services, you can rest easy knowing your home is safer and more efficient.


    Improve Energy Efficiency

    Energy efficiency is an important aspect to consider when it comes to new windows. The windows of a home are responsible for a significant amount of heat loss or gain, which can greatly affect the energy consumption and the overall comfort of a home.

    Lower your energy costs

    New windows use less energy by providing better insulation and reducing drafts. They can also help to keep the heat out in the summer and keep it in during the winter. This can result in a significant reduction in energy consumption and a corresponding reduction in cost.

    Save money with Fibrex® from Anderson

    If energy savings is your top priority, consider Fibrex® from Anderson. This advanced material provides exceptional energy savings that far surpasses both wood and vinyl windows. Fibrex® is incredibly strong and weather resistant for long-lasting performance, and offers excellent sound insulation for a tranquil atmosphere inside the home. With the added bonus of unprecedented energy savings over time, Fibrex® offers an ideal solution for new windows.

    How to Tell When it's Necessary to Replace Your Windows

    If you have a home in Fort Collins, window replacement should be sought if you're having issues with physical damage, condensation, or drafts.


    • Physical Damage such as rotting, warping or cracks on the window frame
    • Appearance of moisture between the glass panes, indicating a broken seal
    • Single-paned windows with no insulation or coating
    • Windows that are outdated or no longer match the design of the house
    • Windows that are difficult to clean or maintain.


    If you're experiencing any of these issues, it's time for replacement windows.

    Comfort Like Never Before

    Replacing old windows with energy-efficient windows can be a great way to improve the overall comfort of your home. Newer windows do more than just regulate temperature and reduce drafts - they can also protect HVAC systems from having to work harder in order to support internal temperatures, and have been shown to improve indoor air quality.

    Get rid of glare

    Certain features, such as low-E coatings that block ultraviolet rays, will even help to reduce annoying glare and make a room feel brighter and more inviting. However, depending on the climate that you are in some window types may perform better than others when it comes to optimizing both comfort levels and energy efficiency; so it’s important to ensure that you’re selecting the right one for the job.

    Knowing When to Replace Your Windows

    • Noticeable drafts or air leaks around the window

    • Visible damage such as rotting, warping, or cracks in the window frame
