About

Chicago Windows & Doors was founded on a straightforward premise: that window and door replacement deserves a specialist, not a generalist. In the early years of the company, our founders noticed that homeowners and property managers were routinely receiving poor results from general exterior remodeling contractors who treated window replacement as one line item among many — often underestimating the complexity of Chicago's aging building stock and the demands of its climate. We built this company to do one thing and to do it exceptionally well.

A Company Built Around Chicago's Built Environment

Chicago's architectural diversity is unmatched among American cities. Within a single neighborhood, you may find 1890s Greystone two-flats, 1920s courtyard buildings, 1960s mid-century modernist towers, and contemporary mixed-use developments built last year. Each era of construction used different framing techniques, different rough opening dimensions, and different materials — and each presents a different set of challenges when it comes to replacement. Over 25 years, our estimators and installation teams have developed hands-on familiarity with all of them.

We understand Chicago's Department of Buildings permitting process, the requirements of the Illinois Energy Conservation Code, and the specific performance standards that high-rise and lakefront properties demand. When a project requires coordination with a building's structural engineer, management company, or homeowner association board, we have the experience and professionalism to manage those relationships efficiently. We don't just install windows — we manage projects.

Our Approach to Every Project

Every engagement begins with a thorough on-site assessment. We do not quote from measurements provided by others or from photographs. Our estimators visit the property in person, evaluate the condition of existing frames, sills, flashing, and rough openings, and discuss the client's priorities — whether that is energy performance, aesthetics, budget, or all three. This assessment informs a detailed written proposal that specifies the product, the installation method, the timeline, and the warranty terms. There are no surprises after the contract is signed.

Our installation teams are employees, not subcontractors. They receive ongoing product training from our manufacturer partners — Andersen, Pella, Marvin, and JELD-WEN — and are held to consistent quality standards on every job. After installation, our office team follows up with every client to confirm the work met expectations and to address any concerns before the project is closed. This follow-up process has been part of our standard practice since the company's founding, and it is one of the reasons our client retention and referral rates remain exceptionally high after more than two decades in business.

We serve individual homeowners replacing a single window, condominium associations managing building-wide replacement programs, commercial property owners upgrading aging storefronts, and institutional clients with complex project requirements.
