Portland Team
Smooth Rollin’ Sealcoating and Paving serves St. Helens, the Columbia County seat, running out Highway 30 along the Columbia River. We work the Riverfront District downtown, the residential streets uphill from it, and the commercial frontage along 30 where most of the county’s business sits.
St. Helens is a river town on a slope, and both halves of that matter for paving. The ground falls toward the Columbia across most of the city, which is good news for drainage if the grading is done right and bad news if it is not, because water that finds a path under a driveway on a grade will keep taking it. The Riverfront District is the older building stock, with the tight access and shared approaches that come with a downtown laid out well before modern equipment. Being the county seat also means civic and institutional lots, which need ADA layout done properly rather than approximately.
Nearby we also serve Scappoose, OR, Vancouver, WA, Hillsboro, OR and Forest Grove, OR. See every city we cover on our service areas page.

We deliver exceptional results backed by transparent pricing and a commitment to quality.
Most of St. Helens falls toward the river. Handled correctly that is free drainage. Handled carelessly it channels water under your driveway and undermines the base from below. We survey the fall before we price the job.
Civic, medical and retail lots need compliant stall dimensions, access aisles and signage, not an approximation. We lay out to current requirements and stripe it in the same visit.
One team from excavation through striping. Everything we install in St. Helens carries a 1-year warranty on our workmanship.
A written proposal with the scope and price, base and drainage itemized. No allowances that grow after the work starts.
Every St. Helens job gets the same crew, the same materials and the same walk-through, whether it is a short driveway or a quarter-mile approach.
We offer a full range of asphalt paving and maintenance services to keep your property safe and looking its best.
New driveways and yard surfaces for St. Helens properties, including the long ones. On rural ground the job is mostly base and drainage: a run of a few hundred feet collects a great deal of water, and ground that was farmed or logged before it was built on behaves differently from a graded subdivision lot. We assess subgrade, excavate and compact a base sized for the vehicles that use the property, crown and grade the length so water leaves, then pave. We also handle commercial and yard surfaces where equipment rather than cars is the design load.
Sealcoating and crack sealing keep water out of the base, which on St. Helens ground is the whole battle. Sealcoat shields the surface from UV, rain and vehicle fluids and brings the color back. Crack sealing is where the real value sits: a crack sealed at a quarter inch wide costs a fraction of the pothole it turns into, and on a long driveway a single unsealed crack can undermine a surprising stretch of base. We will tell you plainly when a surface is still worth maintaining.
Striping and layout for St. Helens commercial properties, churches, schools and event parking: ADA stalls and access aisles to current requirements, fire lanes, crosswalks, numbered stalls and custom stencils. We also install speed bumps, wheel stops, signs and posts, and lay out overflow and gravel-edge parking where a property needs organized capacity a few times a year rather than every day.
Potholes, spreading cracks and broken edges get worse fast once water is into the base, and on a long St. Helens driveway a small failure can undermine a long stretch before anyone notices. We handle crack sealing, patching, saw-cut and full-depth repairs, base repair and drainage correction. Timely repair is the cheapest work in this trade, and we would rather do a repair now than a replacement in three years.

We discuss what you need and visit your St. Helens property to assess the existing surface, check the base and take measurements.

Answers to common questions about paving and asphalt work in St. Helens.
Yes, and mostly in your favor if it is built right. A grade gives water somewhere to go, which is the single biggest factor in how long asphalt lasts. The risk is that water finds a path under the edge of the driveway instead of across the top of it, and on a slope it will keep taking that path until the base washes out. We grade the surface and detail the edges so runoff leaves rather than gets underneath.
Yes. Highway 30 frontage lots see steady turnover traffic and often have drainage running toward the road, which needs handling deliberately. We build the section for the traffic, grade so water leaves the lot properly, and handle striping and ADA layout as part of the same job rather than sending a separate crew back.
Paving installs a new surface and is the right answer for new construction or a failed base. Sealcoating is preventative maintenance over asphalt that is still sound, protecting it from UV, rain and vehicle fluids. On a long rural driveway the economics differ from a suburban one: sealing the whole length is a real cost, so we will tell you honestly whether the whole run needs it or only the sections that are actually weathering.
Every two to three years for most St. Helens surfaces, with crack sealing whenever a crack appears rather than on a schedule. Our rainfall is why the interval is shorter here than in drier parts of the country. On long driveways the sections that need attention first are usually the ones under tree cover and the low points where water sits, and it is often sensible to treat those rather than the whole length every cycle.
Usually 24 to 72 hours for cars depending on temperature and thickness, and we give you a specific figure before we leave. If your property sees delivery trucks, equipment or stock trailers, hold those back longer, because heavy weight on asphalt that has not fully hardened leaves permanent ruts. For the first several weeks also avoid turning the wheels of a stationary vehicle and putting stands down without a board underneath.
