Decision Checklist
Pavers vs concrete: cost, lifespan, and which one your lot calls for
Why the comparison lands differently here
In most towns this is a question of taste and budget. In West Hills it is partly a question of geology, because the community sits astride two quite different kinds of ground. The central and eastern tracts near Sherman Way and Vanowen rest on alluvial sands and gravels that drain freely and compact predictably. That is forgiving subgrade, and a well poured slab on it can serve a long time before it complains.
Travel west of Valley Circle Boulevard, toward Castle Peak and the edge of the Simi Hills, and the picture changes. Those sloping benches carry expansive, high-plasticity clay. It takes on water through the winter and swells, then dries through a long hot summer and shrinks back. Anything rigid laid across that movement eventually finds a way to relieve the stress, and in concrete the relief is a crack. That single geological fact is why the same homeowner question produces two different answers depending on which side of Valley Circle the house stands.
The numbers, side by side
| Measure | Interlocking pavers | Poured concrete |
|---|---|---|
| Installed cost | $14 to $25 / sq ft | $8 to $15 / sq ft |
| 400 sq ft patio | $6,000 to $8,800 | $3,200 to $6,000 |
| 600 sq ft driveway | $9,600 to $15,000 | $4,800 to $9,000 |
| Ready to use | Same day the crew finishes | After a curing period, longer before vehicles |
| Repairing damage | Lift affected units, correct base, reset | Patch or saw-cut section, color rarely matches |
| Response to ground movement | Flexes across thousands of joints | Cracks, and the crack propagates |
| Look after several summers | Integral color, light tones hold well | Surface wear, staining, visible joints |
Those installed ranges are the West Hills figures the contractor quotes from. The full breakdown by project type, including what removal of an old surface adds, sits on the West Hills pricing breakdown.
The checklist
Rather than declaring a winner, work down the two lists below. Most homeowners find that four or five items on one side describe their situation plainly, and the decision makes itself.
Choose pavers if
- Your lot sits west of Valley Circle Boulevard, on a bench or a slope, where expansive clay moves seasonally.
- You are replacing a driveway that has already cracked once and you do not want to watch the same thing happen again.
- You want the surface usable the day the crew packs up, with no curing period before you park on it.
- You expect to open the ground later for irrigation, low-voltage lighting, or a gas line to an outdoor kitchen. Pavers come up and go back.
- Hillside or roof runoff crosses the area, and a permeable section could take that water down into a stone reservoir rather than toward a neighbor's grade.
- Appearance matters to you over a long horizon. Integral color in a light tan or warm gray weathers far better through the summers here than a troweled slab surface.
- Your parcel is in or near a very high fire hazard severity zone and you want noncombustible ground supporting defensible space.
- You intend to stay in the house, and total cost over twenty years matters more than the check this month.
Choose concrete if
- The budget is firm and the lower installed cost is the deciding factor, full stop.
- The area is small, utilitarian, and out of sight, such as a side yard pad or an equipment slab.
- Your lot is flat, on the alluvial soil near Sherman Way or Vanowen, and drainage is already resolved.
- You are preparing to sell soon and want a clean, inexpensive surface rather than a long-term asset.
- The design genuinely calls for one continuous monolithic plane with no joint lines.
- You accept that hairline cracking is normal in slabs and will not be troubled by it.
What the checklist does not capture
Two things deserve a sentence of their own. The first is repair economics. When a slab fails, the honest remedy is usually replacement of a whole section, because a patch announces itself forever. When a paver field fails, the remedy is local: pull the affected units, correct the base beneath them, and reset the same pavers. That is why the crew hands homeowners a small stock of matching units at the end of a job.
The second is heat. Summers on this end of the Valley average in the mid to high 90s, 95 in July and 97 in August at the nearest station in the climate record, with strong UV, and the surface you choose has to look respectable after five of them. Light tan, buff, and warm gray pavers carry color through the unit rather than on it, so wear does not expose a different shade underneath. A troweled slab shows its age in a less graceful way, through surface dusting, staining around the drip line, and the darkening that follows repeated pressure washing.
What the contractor actually does on West Hills lots
The way the contractor builds on West Hills ground divides along the same line the geology does. On the flat tracts, where the alluvial soil is genuinely good subgrade, the crew's attention goes to compaction density, consistent base depth in the wheel paths, and building in real fall so the surface sheds water away from the house rather than toward the garage threshold. Those jobs are straightforward, and they sit at the lower end of the paver range.
On the benches and canyon lots to the west, a paver installation is specified rather than simply built. That means deeper excavation, a well-graded aggregate base placed and compacted in lifts, geotextile separation so the base does not migrate down into the clay, subsurface drainage to keep water away from the section, and edge restraint substantial enough to hold under lateral pressure on a slope. Where the work sits inside Bell Canyon, Sterling at West Hills, or Hidden Lake, the crew arranges gate clearance and stages pallets for narrow canyon roads before a start date is set, because material handling on those streets is a real constraint rather than an afterthought.
Whichever surface you land on, the estimate is written, itemized, and free.
Either surface lives or dies on what is under it. What West Hills soil does to dirt-laid work explains that.
