Our Window Services

Window Options For Every Home

FIND THE RIGHT STYLE FOR YOUR SPACE

We install a variety of replacement windows designed to improve your home’s comfort, energy efficiency, natural light, and curb appeal.

Double-Hung Windows

A popular choice for replacement windows, double-hung windows feature two operable sashes for flexible ventilation and easy use. Their classic design works well with a wide range of home styles.

Casement Windows

Casement windows open outward to provide excellent ventilation and an unobstructed view. Their tight seal when closed also makes them a strong option for homeowners looking to improve energy efficiency.

Sliding Windows

Sliding windows open horizontally and offer a simple, space-saving design. They are easy to operate and work especially well in rooms where a wider window opening and plenty of natural light are desired.

Picture & Specialty Windows

Picture and specialty windows can create larger views, bring more natural light into your home, and add visual interest to a room. They can be installed on their own or paired with operable windows to create a custom configuration.

    Why Invest in New Windows/Replacement Windows

    New windows can do much more than update the appearance of your home. Professional window replacement can improve comfort, efficiency, and everyday performance.

    Boost Curb Appeal

    New windows instantly enhance the look of your home, inside and out, with styles and finishes to match any design.

    Improved Energy Efficiency

    Modern, energy-efficient windows help reduce drafts and improve insulation, keeping your home more comfortable year-round and lowering energy costs.

    Increased Protection

    Quality windows help shield your home from harsh weather, moisture, pests, and air infiltration, protecting what matters most.

    Reduced Maintenance

    New windows are built with durable, low-maintenance materials that resist warping, fading, and wear, so you can spend less time on upkeep and more time enjoying your home.

    How Do I Know If My Windows Need to Be Replaced?

    Common signs that it may be time for window replacement include drafts, condensation between panes, difficulty opening or closing windows, damaged frames, outside noise, and noticeable temperature changes near your windows. Older windows may also lack the insulation and energy-efficient features found in newer models.

    Not every problem requires a full replacement. Billy Goat can inspect your existing windows and help determine whether window repair or replacement makes the most sense for your home.

    How Long Do Replacement Windows Last?

    Quality replacement windows can last 20 years or longer when properly installed and maintained. The exact lifespan depends on the window material, construction, exposure to weather, and quality of the original installation.

    Wisconsin weather can be particularly demanding on windows, which makes proper installation and weather sealing important. Choosing windows designed for energy efficiency and year-round performance can help protect your investment over the long term.

    Are Energy-Efficient Windows Worth The Cost?

    Energy-efficient windows can be a worthwhile upgrade, especially if your current windows are old, drafty, or poorly insulated. Modern replacement windows are designed to reduce air leakage and heat transfer, helping your home maintain a more consistent indoor temperature throughout the year.

    In Wisconsin, that can be especially valuable during cold winters and hot, humid summers. New windows can also improve comfort, reduce drafts, and give your home a more updated appearance.

    What to Expect During a Siding Replacement

    We start with an on-site inspection and a clear, written estimate. There are no surprise charges added later. Once you approve the project, we remove the old siding, inspect the sheathing and house wrap underneath, and address any hidden moisture or rot before the new siding goes on. This step matters. Installing new siding over damaged sheathing only hides the problem.

    We then install your chosen siding, along with proper flashing and trim, and complete a full cleanup of the work site. Most residential siding projects are completed in a matter of days, depending on the size of the home and the material selected. We keep you informed at each stage so you always know what is happening and when.

    Should I Repair Or Replace My Windows?

    Window repair may be the right choice when the issue is isolated, such as damaged hardware, minor frame damage, or another repairable component. Replacement is often the better long-term option when windows have failing seals, extensive damage, recurring drafts, poor energy efficiency, or are approaching the end of their expected lifespan.

    Billy Goat provides both window repair and window replacement services, so we can evaluate the condition of your windows and recommend the most practical solution rather than automatically recommending replacement.
