Replacement Windows Features
100% Virgin Vinyl
Our premium virgin vinyl frames, inspired by top brands like Pella, ensure unmatched durability and energy efficiency. Unlike wood, they won’t warp, rot, or need painting, saving homeowners hundreds in maintenance over years—based on our extensive installation records.
Improved Aesthetics
New windows instantly elevate your home’s look, with styles and finishes tailored to Chicago’s diverse architecture. We’ve seen clients in Lincoln Park boost property value by 10% through modern designs, aligning with industry trends reported by the National Association of Realtors.
Multi-Chambered Frame
Engineered for superior insulation, our multi-chambered frames cut noise by up to 50%, per National Fenestration Rating Council tests. Perfect for busy Chicago streets, they’ve helped families enjoy quieter, more comfortable homes while lowering energy costs.
Argon Glass Filling
Our double-pane windows with argon gas filling minimize heat transfer, keeping homes warmer in winter and cooler in summer. This technology, backed by U.S. Department of Energy standards, has reduced heating bills for our clients by up to 25%.
Dual Layered Low-E Glass
Featuring dual Low-E coatings, our windows reflect heat while maximizing natural light. This balance improves comfort and cuts energy costs, a benefit we’ve verified through thousands of installations across Chicagoland.
Increased Safety
Equipped with multi-point locking systems meeting ASTM standards, our windows offer superior protection. Families we’ve served in Oak Park and beyond trust us for peace of mind, backed by our rigorous quality checks.
