Understanding Wall Cracks and Drywall Cracks in New England
Drywall cracking is a common sign indicating the need for foundation repair. Cracks in drywall occur when it becomes overloaded or when the structure settles or heaves. Vertical and angled cracks typically result from settlement or heaving, while horizontal cracks are often due to lateral pressure.
Settlement isn't uniform; some parts of a structure settle before others, causing cracks. These are generally found where the ceiling meets the wall, a result of downward movement. Another common location for settlement cracks is along the top edge of a door frame, with diagonal cracks that grow as the house settles.
Moisture can also accumulate behind drywall. Without a vapor barrier, moisture can infiltrate from outside, passing through the wallboard and collecting near the studs. Additionally, moisture can reach the drywall screws, causing them to rust. The expanding rust eventually leads to drywall cracking.
Water and Foundation Problems
Water is often mistakenly blamed for foundation problems, but understanding its true role is crucial. While water can indeed be a cause, such as when hydrostatic pressure builds behind walls due to poor drainage, it is frequently the settling of the foundation that's the real culprit. This settling often goes unnoticed until the rainy season, when water infiltrates and exposes the cracks.
Repairing foundation issues without addressing the water's impact and the settling itself can lead to further complications. Recognizing when water is a symptom rather than the cause helps in targeting the real issues effectively.
