Cornerstone Paving WA is a licensed chip seal contractor serving Spokane Valley, WA and the surrounding Eastern Washington region. We provide professional chip seal paving for long driveways, rural properties, acreage access roads, and private roads throughout Spokane Valley.
If you need a durable, weather-resistant surface at a lower cost than full asphalt paving, chip seal is worth a serious look. We are Washington State licensed (CORNECL750Q4), fully insured, and offer free written estimates with no obligation.
Chip seal combines hot liquid asphalt binder with embedded crushed stone aggregate to create a textured, weather-resistant driving surface. It is not asphalt paving, and it is not gravel. It sits between the two in terms of cost and finish, and for the right property type it outperforms both on value.
Chip seal is best suited for long driveways, acreage properties, ranch and farm access roads, and private roads in Spokane Valley where the square footage involved makes full asphalt paving cost-prohibitive. It handles Eastern Washington freeze-thaw cycles well, provides strong natural traction, and drains effectively when installed with proper surface grading.
For shorter residential driveways with regular passenger vehicle traffic, asphalt paving is often the better fit. We assess your property in person and give you an honest recommendation before you commit to anything. Visit our Asphalt Paving page if you are comparing the two options.
We install chip seal surfaces for homeowners across Spokane Valley with long driveways, large lots, and acreage access roads where full asphalt paving would cost significantly more without adding proportional value. Our residential chip seal process covers full surface preparation, drainage grading, edge definition, and two complete applications of polymer-modified asphalt binder and crushed stone aggregate. The result is a tight, bonded surface that handles Spokane Valley winters and resists loosening under regular residential traffic.
For commercial property owners and managers in Spokane Valley needing a cost-effective surface for large areas, access roads, or secondary parking surfaces, chip seal provides a practical solution at a competitive price per square foot. We handle site assessment, surface preparation, and installation with minimal disruption to your operation. Written estimates are provided upfront and the price you are quoted is the price you pay. A chip seal surface on a large commercial property costs considerably less to install and maintain than full asphalt paving across the same area.
Long private roads and acreage properties in the Spokane Valley area are exactly what chip seal was designed for. Full asphalt paving across a few hundred feet of private road or a large rural driveway adds up fast. Chip seal delivers a durable, all-weather driving surface across those distances at a fraction of the cost, without sacrificing performance in Eastern Washington conditions. We have completed chip seal installations on rural properties and long access roads across Spokane Valley and surrounding communities including Greenacres, Otis Orchards, Liberty Lake, and Deer Park.
Most chip seal contractors in Spokane Valley install a single application of binder and aggregate. Cornerstone Paving WA installs a full double chip seal system on every residential and commercial job.
A double chip seal means two complete applications of polymer-modified asphalt emulsion and crushed stone, each compacted separately before the next layer goes down. The result is better stone retention, a tighter surface mat, less loose rock over time, and a more durable finished surface that holds up longer through Spokane Valley’s seasonal conditions.
Most homeowners are surprised to find that our double chip seal pricing is competitive with, and in many cases lower than, what other contractors charge for a single application. You get more for less. That is a difficult combination to find.
Chip seal costs significantly less per square foot than asphalt paving. For long driveways, private roads, and large acreage surfaces, the savings are substantial.
Asphalt creates a smooth, compact surface. Chip seal creates a textured, aggregate surface with natural traction. Both are durable and weather-resistant when installed correctly.
Asphalt paving is better for short residential driveways and high-traffic commercial parking lots. Chip seal is better for long driveways, rural access roads, and large surface areas where cost per square foot matters.
Both surfaces benefit from periodic maintenance. Chip seal surfaces may shed minor loose stone in the first few weeks after installation as the surface settles. This is normal and stops as the stone fully embeds into the binder.

A properly installed chip seal surface in Spokane Valley typically lasts 7 to 10 years depending on traffic volume, drainage conditions, and how well the surface is maintained. Our double chip seal system extends that lifespan compared to single application work.
Some loose stone shedding is normal in the first two to four weeks as the surface fully settles. This is expected and stops on its own. We explain what to expect before we leave the site so there are no surprises.
We typically recommend waiting 24 to 48 hours before regular vehicle use. We confirm the exact timeframe for your specific job before we finish on site.
We offer 1/4 inch fine grain for a smoother, tighter residential finish, 3/8 inch standard grain for most residential and rural applications, and 1/2 inch coarse grain for high-traffic or rural surfaces where maximum grip is the priority. We also offer traditional black and contemporary grey aggregate finishes.
