Plaster walls add timeless charm and elegance to any home, but cracks can appear over time, often signaling underlying structural or environmental concerns. At Worldgate Plaster & Stucco Company, we help homeowners in Reston, Virginia, and the surrounding areas recognize and repair these issues before they worsen. Addressing plaster cracks before winter arrives is essential to prevent costly repairs and preserve the integrity and beauty of your home.

Understanding the Causes of Plaster Cracks

Structural Settling and Movement

As homes age, minor settling or shifts in the foundation can place stress on plaster walls. Cracks frequently appear near doorways, windows, or corners—areas where movement is concentrated.

Chimney-Related Shifts

Chimneys expand and contract with temperature changes, which can transfer stress to nearby plaster walls. Left unchecked, this can worsen cracks or even compromise structural elements.

Weakened Lath Support

Traditional plaster is applied over wooden lath, which serves as a framework to hold the plaster in place. Over time, lath “keys” may loosen or weaken, allowing cracks to form, particularly in older homes.

Temperature Fluctuations and Seasonal Expansion

Wood and plaster naturally expand and contract with seasonal temperature changes. These subtle movements can cause hairline or more pronounced cracks, especially in areas exposed to repeated heat and cold cycles.

Why Timely Repairs Are Crucial

Delaying plaster repair until after winter can lead to more significant issues. Cold temperatures and moisture increase the risk of cracks worsening, water infiltration, and even plaster sections loosening or falling. Early intervention preserves your home’s beauty, prevents further damage, and helps maintain energy efficiency by reducing drafts and insulation gaps behind walls.
