Windows in Iowa take west wind and, in hail, a direct hit the roof does not always share. A spidered pane with the shingles still in place is a window call. Screens tear. Trim dents. A meeting rail that whistles all winter is a separate complaint from storm glass. Fog between panes means the seal died, whether or not a stone of ice found it. Wood sash on older town houses swells in humid summers and sticks shut.
Say which wall faces the weather. The west elevation takes the storms. North walls take the winter draft. Wind-driven rain enters beside the frame on brick as often as through the glass. Look for stained plaster at the corners before you blame the sash. A rotten sill is not a fogged unit. Loose storms rattle and trap moisture on the wood. If a bedroom must open, say so.
A repair can be one pane, one storm, a lock, or a cord when the frame is solid. A whole-house replacement is a different sentence. Ask what happens to interior trim and the exterior wrap. On brick, the joint at the casing has to be in the plan. On a ranch with flanges, the wrap and the flange decide whether the opening stays weather-tight. This wind will find the gap you skip.
Count the openings that are actually failing. Draft, leak, fog, or broken glass is enough to start. Do not turn a cracked west pane into a speech about every window. If hail marked the gutter and the glass, say both, and keep them as two facts. Hardware can wait. A hole you can feel cannot.
Lead with the town and the wall. Name broken glass if that is what the storm did. Iowa will throw the next cell at the same face. Call the number on this page.
