Driveway Resurfacing in St Helens, Oregon: Cost & Process

Driveway Resurfacing in St Helens

When a St Helens driveway starts looking tired — faded gray, surface cracks spreading, a few rough patches — the question is whether to resurface it or tear it out and start over. Resurfacing, also called an overlay, lays a fresh layer of hot-mix asphalt over the existing driveway. Done on a sound base, it restores the surface for a fraction of the cost of full replacement. Done over a failing base, it's wasted money. Knowing which situation you're in is the whole game.

In Columbia County, where wet winters and a high water table put steady pressure on asphalt from below, that distinction matters even more than in drier regions. This guide explains when resurfacing makes sense for a St Helens driveway, what it costs, and how the lower-Columbia climate factors in.

What Resurfacing Actually Is

Resurfacing means cleaning and prepping the existing driveway, repairing localized damage, and then paving a new asphalt layer — typically 1.5 to 2 inches — over the top. The old asphalt becomes the base for the new surface. The result looks and performs like a new driveway, as long as the structure underneath is still solid.

The key word is underneath. Resurfacing fixes the top. It does nothing for a cracked, water-saturated, or settling base. In St Helens that's a real consideration, because the most common cause of driveway failure here is water working its way under the asphalt over many wet winters.

When Resurfacing Is the Right Call

Resurfacing is a good fit when:

• The base is still solid and the driveway hasn't heaved, sunk, or shifted
• Damage is surface-level: fading, shallow cracks, raveling, minor potholes
• The driveway drains reasonably well and isn't sitting in standing water
• The existing asphalt is generally intact, not crumbling across large areas
• You want to extend the life of a driveway that's structurally sound but cosmetically worn

When resurfacing is not enough:

• Wide alligator cracking across large sections (a sign of base failure)
• Areas that pump water or stay soft and spongy after rain
• Significant settling, dips, or heaving
• The driveway is at or past the end of its structural life

What Resurfacing Costs in St Helens

Industry baseline ranges shown below. Actual costs vary with driveway size, condition, prep work, and current asphalt pricing.

Driveway Size	Approx. Square Footage	Industry Baseline Range
Small (1 car)	400–600 sq ft	$1,200–$3,000
Medium (2 car)	600–1,000 sq ft	$2,000–$5,000
Large (3+ car)	1,000–2,500 sq ft	$4,000–$12,000

Per-square-foot baselines for an asphalt overlay have historically been reported around $3 to $7, generally running 40 to 60 percent less than full replacement. St Helens projects can run higher when extra crack repair, patching, or drainage correction is needed before the overlay goes down.

The Resurfacing Process

1. Cleaning — The surface is swept and washed; vegetation, debris, and loose material are cleared.
2. Crack and pothole repair — Existing cracks are filled and any potholes patched so they don't telegraph through the new layer.
3. Leveling — Low spots and dips are brought up with leveling course so the finished surface drains correctly.
4. Tack coat — A bonding layer is applied so the new asphalt grips the old.
5. Paving — Fresh hot-mix asphalt is laid and compacted with a roller.
6. Cure — The new surface is drivable quickly but should cure before heavy loads or sealcoat.

Why the St Helens Climate Matters

A resurfaced driveway is only as good as the surface it sits on, and lower-Columbia weather is hard on that surface. Long wet winters mean water is almost always present, and if it can get under the asphalt through unsealed cracks or poor drainage, it undermines both the old layer and the new one. Before resurfacing here, a good contractor checks drainage and seals the cracks that let water in — otherwise the same problems return.

There's also the freeze-thaw factor. St Helens doesn't get the brutal cold of eastern Oregon, but it does cycle around freezing through the winter. Water that seeps into cracks expands when it freezes, widening them. Resurfacing on a sound base and keeping up with crack sealing afterward is what gets you the full life out of an overlay.

Timing Your Resurfacing Project

Resurfacing, like new paving, needs dry conditions and temperatures generally above 50°F. In St Helens that means late spring through early fall. Trying to overlay during the wet season leads to poor compaction and a surface that won't bond or cure properly. Plan the work for summer, and book ahead — the local paving window is short and demand clusters into those few dry months.

Getting the Most From an Overlay

Once your driveway is resurfaced, a little upkeep keeps it healthy: sealcoat it after it has fully cured and then periodically, fill new cracks before winter, and keep water draining away from the edges.
