Choosing Replacement Windows for a Chicagoland Home

Frame Materials

Vinyl frames are the most common choice in the western suburbs because they never need painting, resist moisture and carry a lower price per opening. Fiberglass costs more but expands and contracts at a rate closer to glass, which keeps seals tight through Chicago winters and hot, humid summers. Wood remains the choice where interior millwork, historic character or a specific stain has to be matched, and it can be clad on the exterior so the maintenance stays manageable.

There is no single right answer. On most projects the material is chosen opening by opening: vinyl across the rear elevation, a clad wood unit in a front room where the trim is visible from the street.

Operating Style

Double-hung windows slide vertically and tilt in for cleaning, which makes them practical on second floors. Casements crank outward and seal tightly against the frame, so they perform well on windy elevations and above kitchen counters. Sliders suit wide openings, and bay or bow units add usable interior space and light to a single room.

Repair or Replace

Fogged glass between the panes, sashes that will not stay up, drafts you can feel with a hand on a cold day, or rot in the sill are signs the unit has reached the end of its service life. A single failed balance or a worn weather strip is usually worth repairing. When several symptoms appear across the same elevation, replacement is normally the better long-term investment.
