Serving Homeowners in Middletown and Across East-Central Missouri

Renewal by Andersen is proud to bring our industry-leading window and door solutions to the Middletown community and the surrounding region. We understand the specific needs of Missouri homeowners and have perfected our process to meet them. Climate & Weather: From hot, humid summers to freezing, icy winters, Missouri's weather is a true test for any window. Our exclusive Fibrex® material is engineered for this challenge, providing twice the strength of vinyl to resist cracking, warping, and peeling in any temperature. Our High-Performance™ Low-E4® glass provides superior year-round insulation, helping to lower your heating and cooling bills. Air Quality: Our windows are designed for a tight, secure seal that helps keep out summer humidity and stops cold winter drafts in their tracks. This also significantly reduces the infiltration of agricultural dust and seasonal allergens, creating a more comfortable indoor environment. Local Architecture: We offer a wide selection of styles that honor the architectural heritage of our region, from historic brick homes in the Missouri Rhineland to classic farmhouses and ranch-style homes in the countryside. We have the expertise to ensure your new windows complement your home's unique character. Homeowner Lifestyle: Enjoy greater peace of mind during Missouri's storm season and save money on your energy bills year-round. Our windows also provide excellent noise reduction, quieting traffic from roads like I-70. The low-maintenance benefits of our products mean you can spend less time on upkeep and more time enjoying your home. Geography & Views: Let us help you frame the beautiful, scenic views of Missouri's rolling hills, river valleys, and picturesque farmland. Installation Experience: You can expect a professional and respectful installation from our dedicated Certified Master Installers, who bring an unparalleled level of skill and attention to detail to every project.

Frequently Asked Questions

We serve homeowners in Middletown and throughout the East-Central Missouri region, including the communities of Montgomery City, Warrenton, Hermann, Wellsville, New Florence, and other towns in Montgomery, Warren, and Gasconade counties.

They are built to be Missouri-tough. Our exclusive Fibrex® window material is twice as strong as vinyl, offering superior resistance to damage from hail and high winds associated with severe thunderstorms. It also withstands extreme temperature cycles without failing, ensuring a lasting, weather-tight seal.

Delaying window replacement can lead to high energy bills for both heating and cooling. Old windows with failing seals are also prone to leaks during heavy rain, which can cause costly water damage, and they make your home feel drafty and uncomfortable. They also allow for the constant infiltration of dust and allergens.

You should consider replacement if you feel drafts, see condensation between the glass panes, have difficulty opening or closing your windows, or notice your utility bills are creeping up. Even windows that are just 8-12 years old can lose significant insulating power, making an upgrade a smart investment.

Your project will be completed exclusively by our own professionally trained Certified Master Installers. We manage the entire process, from design to installation and warranty, to ensure you receive the highest quality of service and workmanship.
