Frequently Asked Questions

Decatur's climate presents unique challenges for windows and doors, with temperature swings from below 19°F in winter to above 87°F in summer. Homeowners should prioritize materials like Fibrex® that resist warping in high humidity (which reaches 73% in July) and maintain structural integrity through freeze-thaw cycles. Energy-efficient glass with Low-E coatings is essential for managing heat transfer during extreme temperatures, while proper weatherstripping and seals protect against Decatur's 40 inches of annual rainfall and occasional severe weather events.

Yes, Decatur's historic districts, particularly in the West End, require Certificates of Appropriateness for exterior modifications including window replacements. While like-for-like replacements may qualify for simplified approvals, changes to window style, size, or material typically require review by the Historic and Architectural Sites Commission. Renewal by Andersen works with homeowners to navigate these requirements, offering historically appropriate options that maintain architectural integrity while providing modern energy efficiency and performance benefits.

In Decatur, double-hung windows remain the most popular choice for Colonial and Victorian homes due to their traditional appearance and versatility. For mid-century ranch homes, which are common throughout the city, sliding windows and picture windows offer clean lines and maximum views. Casement windows are gaining popularity for their superior energy efficiency and ventilation control—particularly valuable during Decatur's humid summers. Each style can be customized with grille patterns and frame colors to complement the diverse architectural styles found throughout Macon County.

Yes, Decatur homeowners can access several energy efficiency incentives when replacing windows. ComEd Energy Efficiency Program offers rebates ranging from $40-$200 for ENERGY STAR® certified windows that can reduce heating and cooling costs by 12-33%. Additionally, the Illinois Weatherization Assistance Program provides support for qualifying low-income households through C.E.F.S. Economic Opportunity Corporation. Renewal by Andersen windows meet or exceed these energy efficiency standards, helping homeowners maximize available incentives while enjoying long-term energy savings in Decatur's variable climate.
