FAQ Q: What causes foundation problems in Philadelphia? A: Foundation issues in Philadelphia commonly stem from expansive clay soils that swell and contract with moisture changes, poor drainage around the home, tree root intrusion, or inadequate compaction during original construction. Seasonal weather patterns can accelerate these issues over time. Q: What are the warning signs of foundation problems? A: Key indicators include cracks in drywall or brickwork (especially diagonal cracks at door and window corners), doors and windows that stick or won't close properly, floors that slope or feel uneven, and visible gaps between walls and ceilings or floors. Q: Is foundation repair a permanent fix? A: The durability of a repair depends on the method used and whether the underlying cause is addressed. Pier-based underpinning systems come with long-term or lifetime warranties from reputable contractors. Addressing drainage and grading issues alongside the structural repair significantly improves long-term outcomes.
