Moisture Is the Primary Threat to Siding in Lewisville WA
Clark County averages over 40 inches of annual rainfall, and Lewisville properties with mature tree cover face additional moisture load from needles and debris collecting at trim lines and panel seams. Water that pools at horizontal surfaces works behind siding through failed caulk joints, cracked panels, or inadequate house wrap installation.
Once moisture reaches the substrate, the problem is no longer just a siding issue—it affects the walls themselves. Moisture can cause siding damage and lead to sheathing and framing issues within the wall structure. Storm damage siding repair Lewisville WA calls frequently uncover rot in the walls that was invisible from outside. A photo-documented siding inspection from Valiant identifies moisture intrusion and siding damage at the siding level before it reaches the structure.
