What does paving cost in Sonoma County?
Any firm price without seeing your site is a guess, because cost depends on what the ground needs first. A new asphalt driveway usually runs about 7 to 13 dollars a square foot. Poor soil or drainage can add 15 to 25 percent.
There is no honest flat per-foot price that fits every job, because the work under the asphalt varies so much from site to site. A real number comes from looking at your specific project.

The ranges
In 2026, a new asphalt driveway runs about 7 to 13 dollars a square foot installed. An overlay on a sound base runs 3 to 7. Sealcoating runs 15 to 35 cents. These are real local ranges, but the final number depends on your site, so treat them as a starting point, and we confirm the real number on site.
What moves the price
Size, asphalt thickness, base depth and condition, soil, drainage, access, slope, and removing the old surface all move the number. Poor soil or bad drainage can add 15 to 25 percent, because the ground needs more work before paving. We give you a real written price after we see the site.

Beware of quotes given sight-unseen, they almost always change. A walk of the site is the only way to price paving honestly.
