What Are Drywall Cracks?

Foundation Crack Repair LLC has decades of experience diagnosing and resolving foundation issues across Long Island. This page explores the best methods for sheetrock seam crack repair — and why getting the underlying foundation issue right is what makes the repair last.

Drywall cracks are fissures in the panels that form interior walls and ceilings, often indicating foundation settlement or shifting. Because drywall is non-structural, it easily cracks when the foundation moves.

  • Diagonal lines extending from door or window corners toward the ceiling.
  • Hairline cracks in drywall above interior doors and windows.
  • Horizontal cracks in drywall along walls and ceilings.
  • Sheetrock cracks running along seams.

What Causes Drywall Cracks?

Settling and Soil Movement

All homes experience some natural settlement as the soil beneath shifts due to natural causes like erosion, expansion, or compaction. Sheetrock and drywall cracks easily appear.

Home Renovations

Home improvements, remodeling, and additions can lead to uneven weight distribution, foundation strain, and drywall cracks.

Water Damage

Water intrusion from leaky pipes, roof leakage, or clogged gutters can weaken or erode the soil surrounding a home's foundation, leading to drywall cracks.

Structural Foundation Issues

Problems such as sinking foundations or bowing walls lead to drywall cracks as well.

How to Repair Drywall Cracks

Drywall cracks are often dismissed as cosmetic. It’s tempting to patch or skim-coat the wall and call it done — but those are temporary DIY fixes that don’t address the underlying cause of the damage. At Foundation Crack Repair LLC, we identify and solve the foundation issue first, then restore the drywall — for a durable, long-term repair.

Hairline Cracks in Drywall

DIY patching or painting might temporarily resolve the issue but the problem may return if the underlying cause isn't addressed.

Major Cracks

Large drywall cracks often require professional intervention, including foundation jacks, footings, waterproofing, or wall reinforcement followed by drywall replacement.
