History of Simonton Windows

Simonton Windows originated as a family business in 1946, when it first began making aluminum windows. Sensing changes in the air, in 1981 the company shifted its focus and retooled to produce energy-efficient vinyl windows. They were one of the first companies to do so, and the move gave them a distinct competitive advantage.

For years part of Fortune Brands Home & Security, since 2014 Simonton has been a member of the Ply Gem Industries group, a corporation tightly focused on windows, siding, other exterior home products.

Today, Simonton makes vinyl windows and patio doors and offers 11 products lines—nine types of windows in all the standard configurations, and both swinging and sliding patio doors. Simonton offers both replacement windows for retrofit remodeling and units designed for new construction. Their products carry all the standard Energy Star ratings and include 20-year warranties on glass and lifetime warranties on vinyl frames, hardware, and screens. This makes Simonton quite comparable to other major window manufacturers in terms of product performance and guarantees.

Simonton products are available in a variety of exterior and interior colors, and in several glazing options, ranging from single-pane glass to double- and triple-pane IGUs with gas-filled chambers and a variety of coatings.



Window manufacturing is a highly controlled and predictable environment, with strict quality checks that seek to ensure that no bad windows ship out. Problems with windows almost always can be traced back to one of two issues:

  • Installation: Installation is arguably the most important event in the history of a window. The finest window in the world can fail quite quickly if the installation is shoddy. The quality of the installation can tip from good to bad based on the company you choose, the skill of the individual installer, and even his whims at that moment. Thus, picking a great contractor is nearly as important as picking a window brand. We here at Colonial can help!



Simonton windows and patio doors are very well constructed. They are ideal if you want cost-effective and energy efficient vinyl windows, ones that are likely to last for many decades if properly installed. Simonton products are largely free of defects and are backed up with excellent warranties. Give us a call we will set your home up with the right windows and doors.
