Chicago's Trusted Window & Door Replacement Specialists

Replacing windows and doors in Chicago is not the same as replacing them anywhere else. The city's climate — lake-effect winds off Lake Michigan, temperature swings of 100°F between seasons, and humidity levels that expand and contract frames year after year — puts extraordinary stress on building envelopes. At Chicago Windows & Doors, we have spent over 25 years solving exactly this problem for homeowners, condo associations, building managers, and commercial property owners across the Chicagoland area.

We made a deliberate decision early on to focus exclusively on window and door replacement. We don't do roofing, siding, or general contracting. That singular focus means our estimators, project managers, and installation teams have accumulated a depth of product knowledge and field experience that generalist contractors simply cannot match. When we walk a building, we immediately recognize whether a frame has suffered moisture intrusion, whether a sill is losing thermal efficiency, or whether an outdated aluminum storefront system is costing a property owner thousands in heating and cooling each year.

Our client base spans the full range of Chicago's built environment. For individual homeowners, we handle single-window replacements and whole-house projects alike, respecting Chicago's diverse housing stock — from vintage two-flats and courtyard buildings in Logan Square and Pilsen to newer construction in the West Loop and South Loop. For condominium and homeowner associations, we manage large-scale replacement programs that coordinate around residents' schedules and comply with association specifications. For commercial clients — office buildings, retail storefronts, hotels, and institutional properties — we work with commercial-grade aluminum and glazing systems engineered for mid- and high-rise performance.

Every project begins with a no-obligation on-site estimate. Our estimators don't send quotes from photos or online forms — they visit the property, inspect existing frames and sills, assess drainage and flashing conditions, and discuss energy performance targets before recommending a solution. We work with a carefully selected portfolio of manufacturers including Andersen, Pella, Marvin, and JELD-WEN, giving us the flexibility to recommend the right product for the right application rather than pushing a single line. The result is a replacement that performs reliably for decades, not just until the warranty expires.
