- Resurfacing and overlay
- Full removal and replacement
What Is Double Chip Seal?
Chip seal uses binder and crushed stone at a lower cost. It suits rural and long driveways.
A double chip seal uses two layers of binder and aggregate instead of one. The result is a tighter, longer lasting surface with better stone retention.
It is installed as standard on residential driveways.
Why Preparation Matters
Most driveway problems start below the surface. That is why base work is a core part of every project.
It includes:
- Clearing the site and addressing drainage
- Grading and sloping away from structures
- A compacted gravel or crushed stone subbase
Good preparation helps protect your driveway through Washington's freeze thaw winters.
Signs It Is Time to Seal Coat
Seal coating is meant for asphalt in fair to good condition. Watch for these signs:
- The surface fades from black to gray
- Minor hairline cracks appear
- It has been 3 to 5 years since the last coat
Fading and minor cracking suit seal coating. Shifted bases or deep structural damage call for repair or replacement.
Licensed and Insured
Trust matters when work happens at your property. Here is what the company states:
- An active Washington State contractor's license, number CORNECL750Q4
- Full general liability insurance on every project
How a Project Runs
The process is simple and clear:
- An honest on site assessment of the surface
- A clear explanation of your options
- A written, itemized estimate with no added fees after the job starts
- Proper base preparation, including gravel subbase, drainage and grading
- Installation by the crew, with the owner on site
- A final check
The company says it does not consider a job done until the surface is right and you have seen it yourself.
How Long Does It Take?
Most residential driveway projects finish in one to two days. Seal coating and chip seal are often completed in one visit.
A timeline is shared before work starts.
