With decades of hands-on experience passed down through three generations, we know what it takes to protect asphalt in the Bay Area. Our sealcoating process is built to defend your lot from sun, rain, oil, and daily wear, helping it look better and last longer without the need for costly repairs.
Not all sealcoating products are created equal. That’s why we use professional-grade sealants that stand up to heavy traffic and tough Bay Area weather. When we seal your parking lot, you get real protection, not just a shiny topcoat.
We believe in keeping things simple: no hidden charges, no upsells, just fair pricing and clear quotes. We’ll walk you through exactly what your lot needs and how much it’ll cost, so you can protect your investment without second-guessing the bill.
Sealcoating isn’t just for looks, it’s a smart way to protect your asphalt from the sun, rain, oil spills, and everyday wear that can break it down over time. At Granite Northwest Grading & Paving, we use a proven process that helps your parking lot last longer and stay looking sharp. No shortcuts, no watered-down sealers, just real protection that holds up.
Here’s how we do it:
First thing we do is check out your parking lot. If we find cracks, potholes, or oil spots, we take care of those first. Sealcoating only works if the surface underneath is solid—no sense sealing over damage.
We don’t cut corners here. We blow off all the dirt and debris, and treat any oil stains so the sealcoat sticks the way it should. A clean surface means a longer-lasting job.
Before we lay down sealer, we make sure the cracks are sealed tight. That keeps water out and stops small issues from turning into big ones later.
We apply two thin coats—not one thick sloppy mess that peels in a few months. We use sprayers for the big areas, and take our time with squeegees and brushes along curbs, edges, and tight spots.
After that, we let it sit and cure. Usually takes about 24 to 48 hours, depending on the weather. Rushing it just shortens the life of the work, and we don’t believe in doing things halfway.
Once it’s cured, we’ll re-stripe everything, parking stalls, ADA spots, arrows, you name it. Your lot will look sharp, stay organized, and be ready for business.
When we’re done, it’s not just about looks, you’re getting real protection that helps your asphalt last longer and saves you from bigger repair bills later on.
