#1 Window Replacement Chicago Contractors

A window replacement involves the professional removal of your existing, underperforming windows and the installation of new, high-performance units custom-fit to your home's openings.

A repair (such as recaulking or replacing a single pane) is suitable if the issue is minor and isolated. A full replacement is recommended if the frames are rotting, the seals between double-panes have failed (causing fogging), or the windows are difficult to operate and drafty.

The cost depends on several factors, including the number of windows, the style (double-hung, casement, picture, etc.), the glass package selected, frame materials, and any necessary structural repairs to the rough openings. We provide clear, project-specific estimates so you know exactly what is included.

Several telltale signs suggest your windows need replacement:

• Age: Your windows are 15-25 years old.
• Condensation: Persistent fogging or moisture trapped between the glass panes.
• Drafts: Feeling a noticeable breeze or temperature change when standing near the window.
• Difficulty Operating: Windows that are painted shut, warped, or require significant effort to open and lock.
• Decay: Visible rot or soft spots on the wooden frames or sills.

While glass-only replacement is possible, it often fails to address the root cause of inefficiency, which is the frame. If the frame is warped or the seals are degraded, new glass won't stop drafts or prevent future rot. A full-frame replacement ensures every component is healthy, secure, and covered by a comprehensive warranty.

Most residential window replacements are completed within one to two days, depending on the number of windows. Larger or more complex projects involving custom shapes may take slightly longer.
