Immediate repair is needed when you see loose or detached panels, large cracks that go through the siding, visible rot or mold growth, or gaps that allow water infiltration. These conditions can lead to structural damage if not addressed quickly.
Other urgent signs include warped panels that don’t lay flat, siding that’s pulling away from the house, or interior water stains near exterior walls. After storms, check for impact damage, missing panels, or sections that appear bent or twisted.
Don’t wait on these issues. Water damage behind siding can affect insulation, framing, and interior walls, turning a moderate repair into a major renovation. Early intervention almost always costs less and prevents more serious problems from developing.
