How to Dry Siding

Start by eliminating any standing water on the siding surface. A window squeegee or a soft broom works well for pushing water off vinyl, wood, or fiber cement panels. Work from the top down to prevent drips from re-wetting areas you have already cleared. This first step reduces the immediate water load and speeds up the overall drying process significantly.

After surface water is gone, inspect for trapped moisture. Pay close attention to seams, joints, and areas behind shutters or trim. If your siding is wood, look for signs of swelling or buckling. Vinyl siding can trap water behind it, which may require you to gently lift a bottom panel to allow it to drain out effectively.

Wet siding often indicates a larger problem: water inside your wall. Check interior walls directly opposite the wet siding for soft spots, stains, or a musty smell. Use a moisture meter on the drywall or plaster if you have one. This inspection is critical because hidden dampness can lead to structural rot and mold growth much faster than the visible siding damage.

If you find interior moisture, you need to address the wall cavity. This might involve removing a section of interior drywall to allow the wall studs and insulation to dry. For a thorough assessment, a professional water damage inspection can pinpoint all areas of moisture using specialized tools.

• Probe wood siding with a screwdriver to check for soft, rotten spots.
• Inspect all caulking and sealant around windows, doors, and corners.
• Look for water stains or mildew growth on the siding's surface.
• Check that weep holes at the bottom of brick or stone veneers are clear.
• Ensure gutters and downspouts are directing water away from the wall.
• Feel for dampness on the backside of siding panels if accessible.

Prevention focuses on managing water flow away from your home. Clean your gutters regularly and extend downspouts so they discharge at least five feet from your foundation. Ensure the soil around your home slopes away from the siding. Trim back tree branches and shrubs that hold moisture against the walls or restrict sunlight and airflow needed for natural drying.

Reseal any cracks or gaps in your siding and around penetrations for pipes, wires, and vents. If you live in Meridian, be mindful of irrigation sprinklers that may constantly hit your siding. Adjust them to water the landscape, not the house. Regularly inspect your siding, especially after severe storms, to catch minor leaks before they lead to a major wet wall issue.

• Schedule annual gutter cleaning, especially after fall leaf drop.
• Re-caulk around windows and doors every few years as sealant degrades.
• Install splash blocks or downspout extensions to move water away.
• Ensure attic and crawl space vents are unblocked to reduce humidity.
• Inspect flashing where the roof meets walls, and at chimney bases.
• Consider applying a water-repellent sealant to porous siding materials like wood.
