Why does water show up on the floor and not in the window?
Because the water runs down inside the wall after it gets past the window or siding, and it reaches the floor at the bottom plate or under the sill. The window may look dry from the inside because the path is hidden.
Water that enters a wall follows gravity, so it travels down the cavity between the sheathing and the drywall until it finds a low point. The bottom plate and the flooring at the wall are where it collects, and the stain appears there several days or weeks after the storm. That is why a homeowner who finds a soft baseboard should check the wall above it, not just the carpet.
The same path explains why a window can seem to leak only in one wind direction. Wind-driven rain goes under the sill or behind siding on the windward side, and the water can stay in the wall until the next rain adds more.
Is a cracked window covered by a homeowner policy?
It depends on the policy and on how the damage was caused. Hail and wind are often named perils on a homeowner policy, but the terms on glass, screens and interior water vary, and the insurer decides each claim.
A policy generally treats the sudden storm damage to the window or siding as one claim and the water that enters afterward as a separate one. Some policies cover interior water that follows a storm opening; others limit it. The Colorado Division of Insurance regulates insurers in Colorado and takes complaints about how claims are handled. This page does not describe any specific coverage.
Before the window is replaced, photograph the crack, the dent and the gap, and keep the broken pieces until the insurer has seen them. Ask for the adjuster's inspection report in writing.
How is a siding repair matched to an existing wall?
A repair that is not matched carefully shows as a patch. Siding can be discontinued or faded, so the crew records the profile, color and panel width before the old panel comes off.
The first step is to measure the panel and to check whether a matching profile is still made. Where a matching panel cannot be found, the repair is planned around a full wall section, which is more costly and more visible than a single panel. Those choices belong to the homeowner and the contractor who installs the siding, and they are made before any work starts.
Under the siding, the house wrap is checked for tears and the sheathing is checked for soft spots. A new panel laid over damaged wrap will leak again, so the wrap is replaced where it is torn.
What should a homeowner check after the wall is dry?
The window operation, the seal, the caulking at the frame and the sill slope. These are the points where water can get back in after a repair.
Open and close the window and check that the sash sits square in the frame. Look for a gap at the sill and at the head of the frame where a drip could enter. A sill that slopes back toward the wall holds water, so the slope is checked as part of the repair.
After the next wind-driven rain, look at the sill and the baseboard again. A fresh stain means the water is still getting in somewhere, and the repair should be checked before the drywall is painted.
