Washington paver patio cost calculator
Paver installations in Washington run $17 to $35 per square foot installed, against a national midpoint of $20. Seattle-area labour rates and stormwater requirements raise costs.

What drives paver cost in Washington
Seattle-area labour rates and stormwater requirements raise costs. That puts Washington at roughly 118% of the national installed average for segmental paving.
Washington sits in a Mild / Coastal zone, where paving is attacked by nine months of rain, saturated subgrade and stormwater detention rules. Locally that means 6 to 8 inches of crushed surfacing base course of crushed surfacing base course (basalt) under a patio, and more under a driveway. That specification difference is a real line item: every extra inch of compacted base adds material, machine time and haul-off of the spoil it displaces.
Labour is about 40% of a paver job — far more than asphalt, which is machine-placed. That is why paver pricing tracks local wage rates much more closely than asphalt pricing does, and why the spread between states is wider here.
How to read a paver quote
A complete quote names the base depth, the bedding sand type, the joint sand product and the edge restraint. If any of those four are missing, the contractor has room to cut the part of the job you cannot see once the pavers are down.
Compare quotes on base depth first. A $24 per square foot quote with 8 inches of compacted base is cheaper over ten years than a $19 quote with 3 inches, because the second one gets rebuilt.
Washington paver cost by project size
Installed, standard concrete pavers, patio base depth.
| Project | Area | Low | Typical | High |
|---|---|---|---|---|
| Small patio (10 × 12) | 120 sq ft | $1,982 | $2,832 | $4,248 |
| Standard patio (16 × 20) | 320 sq ft | $5,286 | $7,552 | $11,328 |
| Large patio (20 × 30) | 600 sq ft | $9,912 | $14,160 | $21,240 |
| Single driveway (12 × 40) | 480 sq ft | $10,195 | $14,726 | $22,656 |
| Double driveway (20 × 40) | 800 sq ft | $16,992 | $24,544 | $37,760 |
Frequently asked questions
+How much does a paver patio cost in Washington?
Between $17 and $35 per square foot installed, with most homeowners landing near $24. A typical 320 square foot patio therefore runs about $7,552.
+Are paver driveways more expensive in Washington?
Yes — $21 to $47 per square foot, because vehicles require 8 inches of compacted base instead of 4, and 80 mm pavers instead of 60 mm.
+When is the best time to install pavers in Washington?
May through September. Persistent rain — sub-base drainage is the single biggest longevity factor. Booking outside peak season often gets you a better rate, since crews price scarcity in the middle of the season.
+Are pavers cheaper than an asphalt driveway?
No. Asphalt installs at a fraction of the square-foot cost, but pavers last 25-50 years against 15-20 for asphalt and individual units can be lifted and reset. Over the full lifecycle the gap narrows considerably.
+What is not included in a typical quote?
Demolition of an existing surface, drainage work, permits, retaining or step work, and lighting. Add demolition above to see how it moves the total.
+How deep should the paver base be in Washington?
Plan on 6 to 8 inches of crushed surfacing base course of crushed surfacing base course (basalt) for a patio, and add a further two to four inches for a driveway. Washington's nine months of rain, saturated subgrade and stormwater detention rules punishes shallow bases faster than anything else on the job.
+Do pavers handle Washington's climate better than asphalt?
In a Mild / Coastal zone, generally yes. Segmental paving flexes with ground movement instead of cracking, and individual units can be lifted and reset where nine months of rain, saturated subgrade and stormwater detention rules has caused settlement.
+How accurate are these numbers?
They are national averages adjusted by a Washington labour and material factor, not quotes. Site access, slope, soil condition and pattern complexity each move the real number by 10% or more.
