The short answer
How Water Gets Behind Siding
Rain and melting snow can push water through small openings. Caulk that has dried and cracked, missing flashing, or damaged siding joints are common culprits. Wind-driven rain can also force water upward under siding, especially on the lower rows.
Another path is through your roof. If shingles or flashing fail, water can run down the wall cavity and appear behind siding. Leaks from pipes or appliances inside the wall can also show up on the exterior. Finding the exact entry point takes careful inspection.
- Cracked or missing caulk at joints
- Damaged or lifted siding edges
- Faulty window or door flashing
- Roof leaks that travel down the wall
- Condensation from poor ventilation
Check Inside Before Calling Pros
Before you pick up the phone, do a simple indoor check. Feel the walls for dampness, especially near windows and doors. Look at the baseboards and floor for water stains or warping. A moisture meter from a hardware store can help you confirm if a spot is wet.
Also inspect your attic and crawlspace for signs of water entry, like wet insulation or stained wood. This can help you describe the problem clearly. If you find water, turn off the source if it's a pipe or appliance, and move valuables away from the area.
What Pros Can Do for You
Local water damage pros can use tools like moisture meters and thermal cameras to find hidden moisture behind siding without tearing everything apart. They can map the extent of the damage and identify the source, whether it's from rain, a pipe, or an appliance.
They can also dry out the affected area using structural drying and dehumidification equipment. This helps prevent mold and further damage. Depending on what they find, they may need to remove a section of siding to dry the wall cavity and make repairs.
