What Are The Effects Of Water Behind Vinyl Siding?
Many problems can arise if water gets behind your vinyl siding and there are no weep holes.
A small amount of water or snow getting behind the siding might not cause any damage right away, but if you ignore the leak after noticing it or you take too long to see it, you can expect the following problems to develop:
Mold And Mildew Accumulation
Mold and mildew find an ideal growth medium in the moisture trapped beneath the vinyl siding. The sheathing or entire wall becomes more susceptible to breaking as mold and mildew accumulate.
But mold affects more than just the integrity of your walls; it can also cause serious health issues. You may notice a runny nose, wheezing, itchy and dry eyes, and skin becoming irritable and itchy.
Furthermore, it may worsen the severity of an allergic reaction to mold in those who already have asthma or have intense allergic responses to mold and mildew.
Vinyl Siding Deteriorates At A Faster Rate
Most manufacturers advertise vinyl siding to last between 20 and 30 years. However, many don't last that long, as noticeable wear and tear become the standard after ten years.
A significant decrease in vinyl siding's durability is because of the water accumulating behind it. If you don't promptly fix the water leak, the vinyl siding can take on a discolored look.
The Sheathing Rots
Wall sheathing makes the walls sturdy, provides a level surface where you can attach the siding, and improves insulation capacity.
Suppose water gets behind the siding, and you fail to detect it for an extended period. In that case, it can cause the wall sheathing to rot, leading to significant structural problems, especially if the damaged parts continue to deteriorate.
Encourages Pest Infestation
Ignoring the leaking vinyl siding will eventually lead to a pest infestation because of several of the abovementioned symptoms. Some pests and insects can find moisture or mold accumulation within the vinyl siding suitable for them to thrive.
Since beetles feed on mold, expect them to infest your vinyl siding. Although they won't be able to damage your wall foundations, they can make the space unappealing.
Furthermore, dust mites can also be a problem. The tiny hairs on their bodies can cause problems for people with allergies and asthma if they float around the house.
Creates Fissures On Wall Foundations
Water seeping behind vinyl siding is a typical cause of foundation wall fractures, much to the dread of homeowners. Houses with vertical fissures often leak somewhere. And if you don't fix them immediately, they will worsen and threaten the whole structure.
Even if the fractures don't compromise the house's structural integrity, they can be ugly and expensive to repair.
