Asphalt as tough as the Northwest that tests it.
We’ve laid asphalt around Puget Sound for more than twenty years. That’s long enough to know what the rain does to a driveway and what a loaded truck does to a parking lot. New pavement, honest repairs, sealcoating that buys a surface years. If it’s asphalt in Seattle or anywhere across King, Pierce, and Snohomish counties, we’ve cut it out, patched it, or laid it new. Big City Paving & Seal Coating is an asphalt contractor working out of Black Diamond. Estimates are free: call (253) 397-8674.

The ground we stand on.
Half our calls come from a kitchen window overlooking a cracked driveway. The other half come from someone responsible for a lot full of complaints. Different ground, same trade.

Driveways
A Northwest driveway never really dries out. Water stands where the grade settled, moss works into the seams, roots lift the edges a little more every year. We’ve seen every version of it. We grade and pave new driveways, resurface the tired ones, cut out what’s failed, and seal what still has life in it.

Parking lots and private roads
Stand in any lot and we can tell you where it’s going to fail: where the trucks turn, and where the water sits. We mill and overlay, rebuild what’s past patching, fill the potholes that open around utility covers, and lay the stripes back down when the layout’s faded to ghosts.

Seven services, and how to know which one you need.
Asphalt work sorts into three categories: building a new surface, repairing a failed one, and the upkeep that postpones both. Here’s what each service is actually for.

When you’re building (or starting over)
For surfaces that don’t exist yet, or are past the point where repair pays.
Asphalt Paving
New asphalt over a graded, compacted base: laid hot, rolled to grade, pitched so water drains. The base does most of the work. It’s the difference between a surface that lasts and one that doesn’t.
Driveways · parking lots · drive aisles · private roads
Asphalt Resurfacing
A new wearing course over a base that’s still sound, usually after milling off the worn top. It’s the middle option: more than a repair, far less than starting over, and the right call more often than people expect.
Tired driveways · aging lots · worn access roads
When it’s already broken
Repairs work when the damage is local. Here’s what a real one involves.
Asphalt Repair
Cutting the failed section out down to sound material and rebuilding it: cracks, sunken areas, broken edges. A repair that skips the cutting is just a patch, and patches come back.
Driveway edges · lot corners · street sections
Pothole Repair
A pothole is a base problem showing through the surface. We square it up, tack the edges, and compact hot mix flush. That includes the ones that keep reopening around utility covers, which fail for reasons of their own.

Before it breaks
The upkeep that postpones the expensive work, and the markings that keep a lot working.
Asphalt Sealing
A sealcoat protects the binder, the glue holding your asphalt together, from water and UV. It only makes sense over pavement that’s still sound, which is exactly when most people don’t think to do it.
Residential driveways · commercial lots
Asphalt Maintenance
Crack filling, patching, edge work, and re-sealing, on a schedule. Small failures are cheap to fix and expensive to ignore. Maintenance is choosing the first one.
Managed properties · HOA roads · driveways
Parking Lot Striping
Layout and line striping: stalls, aisles, directional arrows, curb and fire-lane marking. New layouts or re-striping over faded paint, so the lot stays safe and easy to navigate.
Retail lots · offices · multifamily · fleet yards

In their words.
Four customers, four jobs, exactly as they wrote it. We wouldn’t change a word, so we didn’t.
