Types of Windows for Your Home

When it comes to selecting the perfect windows for your home, you have a variety of options to choose from. At MGS Contracting Services, we offer high-quality replacement windows designed to enhance the beauty and functionality of your living space.

Double Hung Windows

Double hung windows are a popular choice due to their classic look and practicality. They consist of two sashes that slide vertically, making cleaning a breeze. Choose from various materials, including vinyl replacement windows or wooden windows, based on your preferences and requirements.

Sliding Windows

Ideal for spaces with wider window openings, sliding windows offer a modern and space-saving design. Our window manufacturers provide durable sliding windows in custom sizes to perfectly fit your home.

Picture Windows

If you want to maximize natural light and enjoy unobstructed views, picture windows are an excellent option. These fixed windows don’t open or close, creating a beautiful focal point for any room.

Bay Windows

Enhance both the interior and exterior of your home with bay windows. They protrude from the exterior wall, providing a cozy alcove inside and increasing your living space.

Storm Windows

For extra insulation and protection from harsh weather conditions, consider adding storm windows to your existing ones. They act as an additional barrier, increasing energy efficiency and reducing energy bills.

Hopper Windows

Hopper windows open inward from the top, making them perfect for basement areas or bathrooms. They provide ventilation while maintaining security and energy efficiency.

Single Hung Windows

Similar to double hung windows, single hung windows have two sashes, but only the bottom sash is movable. They offer a timeless look and work well in various architectural styles.


For a touch of luxury and to brighten up interior spaces, consider installing skylights. Our window installers are skilled in integrating skylights seamlessly into your home’s design.

Window Installation FAQs

Window installation in construction refers to the process of fitting new windows into the openings of a building’s exterior walls. It involves removing the existing window (if applicable), properly framing the window opening, installing the new window unit, and ensuring it is securely sealed and weatherproofed. Window installation is a crucial step that enhances a building’s aesthetics, energy efficiency, and overall comfort.
The cost of inserting a window can vary depending on several factors, including the type and size of the window, the material used, the complexity of the installation process, and the specific requirements of your home. Generally, window installation costs can range from a few hundred to several thousand dollars per window. For an accurate estimate, we recommend contacting our team at MGS Contracting Services for a personalized quote tailored to your project.
Window walls, also known as curtain walls or glass walls, are large, floor-to-ceiling windows that provide expansive views and ample natural light. They are typically installed in commercial buildings, modern homes, or spaces requiring a seamless interior and exterior connection. Window walls are installed by assembling the window units off-site and then securing them to the building’s structural framework. This installation method allows for efficient and precise placement of the windows, creating a stunning visual impact.
Yes, windows need to be framed to ensure proper installation and structural integrity. The window frame serves as the support structure that holds the window in place within the opening of the exterior wall. It helps distribute the weight of the window and its components evenly, preventing air and water leakage while maintaining the window’s stability. Proper framing is essential for a secure and long-lasting window installation, ensuring that the window unit functions optimally and complements the overall design of your home.
