Why Headstones Sink and Lean — and How Professionals Fix It

Why stones move

• **Grave settlement.** The disturbed soil of a grave settles for decades.
• **Freeze-thaw cycles.** Water in soil expands when it freezes, heaving foundations a little every winter.
• **Drainage.** Water flowing through a section undermines bases over time.
• **Undersized foundations.** Many older stones were set on little more than tamped earth.
• **Tree roots** lift and tilt anything in their path.

Why it matters

A leaning stone becomes a falling stone. Beyond the disrespect of a toppled marker, falling monuments cause serious injuries in cemeteries every year — and a fallen stone frequently breaks.

How professionals reset a stone

1. The stone is lifted with levers, tripods, or hoists appropriate to its weight. 2. The old base material is excavated. 3. A new base is built — compacted crusher gravel is the modern standard; some cemeteries require poured concrete foundations. 4. The stone is reset, shimmed plumb and level, and checked for stability.

Costs typically run $200–$600 for standard uprights. It is among the most satisfying repairs to see completed — a straightened stone changes the whole feel of a gravesite.
