Custom Windows Installation and Replacement


Whether you’re remodeling your home or building a house from the ground up, new custom windows make a sound choice. This type of window offers many benefits: they can be build-to-order for your home’s window sizes, they can be customized by color or style, and they can be personalized to incorporate the latest efficiency features.

In other words, custom windows allow homeowners to personalize the performance and look of their windows, and they’re sized to fit perfectly.

About Our Custom Windows

WeatherMaster makes it easy to order custom windows. You choose all of the features you want, and we’ll fabricate and install them to meet your specifications. Some of the most common customization options include:

  • Materials: Vinyl, wood, and fiberglass are the most common types of frame material. All of our vinyl windows feature welded frames for maximum insulation.
  • Efficiency Features: Choose the features you want to maximize efficiency. Options include argon and krypton gas fills, Low-E glass, double or tripled-paned glass, and much more. Our top model is actually 270% more energy-efficient than standard ENERGY STAR windows.
  • Colors: Get vinyl windows in a range of colors. Or choose from several classic shades of white.
  • Styles: From double-hung, sliders, picture windows to casement windows, we allow you to customize a variety of styles.
  • Grid Patterns: Choose from several grid layouts for the look you want. From a classic Colonial pattern to a more modern look, we have options to fit every aesthetic.

Are Custom Windows Right for My Home?

Compared to standard windows, custom windows offer some key advantages. Some pros and cons of custom windows include:

  • Sized to Fit: Custom windows can be built every 1/8” to fit your home perfectly, providing better insulation and a cleaner look without fillers.
  • Built-to-Order: Custom windows can be personalized to fit your home’s aesthetic, with options for colors, grid layouts, and hardware.
  • Maximum Efficiency: Made-to-order windows incorporate the latest window innovations to help you better insulate your home.
  • Cost: Custom windows tend to cost approximately 10% more than stock windows.
  • Time to Manufacture: Custom windows do have a longer lead time, and you may have to wait a little longer before installing them.
