A Chicago landlord's guide to spotting winter screen damage, tackling common repairs, and getting every window in your rental building ready for warm weather.
Window screens are the kind of detail tenants only notice when something is wrong. A torn corner letting in mosquitos, a bent frame that will not stay seated in the track, a missing screen on the third-floor bedroom of a Lincoln Park walk-up. For Chicago landlords, the spring inspection of every screen in the building is one of the highest-leverage maintenance tasks of the year. It costs almost nothing in materials, prevents a wave of summer complaints, and signals to renters that someone is paying attention.
By the time mid-May arrives, tenants in Lakeview, Andersonville, and Rogers Park are throwing open windows for the first time in months. Whatever shape your screens are in is the shape they will stay in until October. A single morning of inspection now is far easier than fielding service requests through June and July when your phone is already ringing about air conditioners and stuck garbage disposals.
Chicago winters are unusually rough on window screens. Lake-effect snow piles against frames, freezes, and thaws in cycles that warp aluminum extrusions and bow plastic mesh. Salt-laden wind off Lake Michigan corrodes screen splines and pits the powder coating on aluminum frames. In many older Chicago buildings, the greystones in Logan Square, the 2-flats in Bucktown, the courtyard buildings in Ravenswood, storm windows trap moisture against the screen layer all winter, accelerating rust on the small staples and screws holding frames together.
You should also expect to find squirrel and bird damage in upper-story units, particularly on properties near the lakefront or wooded blocks. Squirrels have been known to chew through fiberglass mesh on Andersonville two-flats to access attic spaces. UV exposure on south-facing windows breaks down the mesh itself, turning what looked fine in September into something brittle by May. The result of all of this is that no screen survives a Chicago winter unchanged.
Run a systematic inspection rather than a glance. Start at the top floor and work down, a habit that catches the worst damage first since upper-story screens take the brunt of wind and weather. Bring a flashlight, a roll of painter's tape, and a notebook or your phone.
For each screen, check four things. First, mesh integrity: hold the flashlight behind it and look for tears, holes, and stretched areas where the weave has separated. Second, frame condition: squeeze each corner and if it flexes more than a hair, the corner clips are failing. Third, spline tightness: the rubber gasket that holds the mesh in place often dries and shrinks, leaving gaps. Fourth, fit in the window track: a screen that does not sit flush is a screen that will not stay put when a tenant raises the sash.
Mark each problem screen with a piece of painter's tape and note the unit number and window location. A typical 24-unit building in Lakeview yields 8 to 12 screens needing attention after a hard winter.
