Hardscaping cost is usually quoted per square foot, but two things decide whether a patio or wall actually lasts and passes inspection: drainage and permits. Most cost guides mention them only in passing.
Quick answer: A paver patio typically runs $15-$45 per square foot installed, with most projects landing in the $18-$35 range depending on region and material. Retaining walls typically run about $20-$35 per linear foot for low landscape walls and $50-$100 or more per linear foot for taller structural walls.
These are general, typical ranges -- your actual bid depends on size, material, site access, and grade, not a flat average.
Typical Cost by Project
| Project | Typical Installed Cost |
|---|
| Paver patio | $15-$45 per square foot |
| Low landscape retaining wall (under about 3 feet) | $20-$35 per linear foot |
| Structural retaining wall (over about 4 feet) | $50-$100+ per linear foot |
What Counts as Hardscaping
Hardscaping covers permanent hard surfaces: pavers, patios, walkways, retaining walls, and pool decks. Covered patios, outdoor kitchens, and fire features belong to Outdoor Living instead, which is a separate kind of project with different Service Professionals.
Permits Are Easy to Miss
Retaining walls above a certain height, and any work that changes drainage or grading, commonly need a permit or engineering sign-off. Requirements vary by area, so ask your Service Professional whether your project needs one before work starts, not after.
Drainage Is the Real Failure Mode
Poorly draining hardscape is one of the most common reasons a paver patio settles or a retaining wall fails early. A proper base and a plan for where water goes matter more than the paver itself. Mention any known water problems, slopes, or low spots in your job post.
Material and Site Access
Concrete pavers are generally the more affordable choice, while natural stone costs more. Curves, patterns, and difficult access (tight gates, no equipment path, steep grade) push labor up. Describe your access honestly so bids reflect real conditions.
Getting an Accurate Bid
Project Genie does not sell materials or set prices -- Service Professionals bid on the job you post. Describe:
- Approximate size -- square footage for patios, length and height for walls
- Material preference, or whether you want advice
- Existing grade and drainage -- slopes, low spots, standing water
- Site access for equipment and material delivery
- Whether a permit may be needed
Frequently Asked Questions
Are pavers more expensive than poured concrete?
Pavers commonly cost more upfront than a basic poured slab, but individual pavers can be replaced if one cracks or settles.
Do I need a permit for a retaining wall?
Often for taller walls or work that changes drainage. Ask your Service Professional to confirm for your area.
Why do patios settle or sink?
Usually a poor base or drainage problem rather than the pavers themselves, which is why those details belong in your job post.
Is a covered patio hardscaping?
No. Covered structures and outdoor kitchens fall under Outdoor Living, a separate category.
