Cost and Considerations for Replacing a Slate Patio with EP Henry Pavers

330 sq ft slate patio destroyed by two harsh winters. Homeowner wants EP Henry or equivalent, contractor-installed.

Cost Breakdown

• Demolition: Slate on mortar bed is labor-intensive. $200–$500+ for removal, haul, dump fees.
• New pavers: $7–8/sf for basic concrete pavers; $12–$18/sf for premium/natural stone look.
• Base prep: 4–6 in compacted aggregate, 1 in sand, edge restraint.
• Total range: $4,000–$8,000+ depending on access, paver choice, region.

Quality Control (Watch the Crew)

• Full mortar bed under each paver—no voids.
• Full joints, tooled clean.
• Seal after 48 hrs; reseal every 2 years.

Why Slate Failed

Water in joints froze, expanded, popped stones. Sealing prevents this.
