Parking Lot Repair
Potholes, alligator zones, raveled edges, sunken patches — fixed before they pull the sub-base apart and force a reconstruction conversation you didn't budget for.
Honest scope, written warranty, single point of contact across MT, ID, WA, ND, and SD. If you need resurfacing instead of repair, we'll tell you — and document why.
What 'Repair' Actually Covers
Most lots don't need a full resurfacing — they need the right repair done once, the right way.
Pothole Patching
Hot-mix, cold-patch, or infrared — selected by depth, traffic, and how long it has to last before the next thaw.
Crack Sealing
Hot-pour rubberized seal on every crack ≥ 1/4" before water gets to the sub-base.
Skin & Full-Depth Patch
Saw-cut, remove failed asphalt, re-compact base, and pave to grade. Sealed at the seam.
Mill & Overlay
Surface mill plus 1.5–2" overlay when alligatoring covers >25% of the lot but sub-base is still sound.
Sub-Base Rebuild
Pump-outs and soft spots traced to drainage or compaction failure — fixed once, not patched annually.
Drainage Correction
Birdbaths, low spots, and curb cuts re-graded so the next repair doesn't fail in the same place.
Repair vs. Resurfacing vs. Reconstruction
The wrong call costs three to five times more than the right one. Here's how we draw the line.
- When
- Failures are localized — potholes, isolated alligator zones, edge raveling, a few hundred sq ft of distress.
- Scope
- Saw-cut + patch, crack seal, infrared, skin patch. Lot stays in service.
- Cost
- Lowest dollar per sq ft on the failed area only.
- Service Life
- Buys 3–7 years if sub-base is sound and a sealcoat plan follows.
- When
- Alligatoring covers >25% of the lot, the surface course is oxidized through, or repeated patches are starting to fail.
- Scope
- Mill 1.5–2", repair base in failure zones, hot-mix overlay, restripe.
- Cost
- Higher per sq ft, but applied to the whole lot — and resets the asset.
- Service Life
- 15–20 years with a written maintenance plan behind it.
- When
- Sub-base has failed — pumping, settlement, drainage rerouted by water instead of design.
- Scope
- Demo, sub-base rebuild, new asphalt, new striping, drainage correction.
- Cost
- Highest — but the only honest answer when the foundation is gone.
- Service Life
- 20–30 years.

Parking Lot Repair, Answered
What is parking lot repair?
Parking lot repair is the targeted fix of localized asphalt failure — potholes, cracks, alligator zones, raveled edges, sunken patches, and drainage low spots — without resurfacing the entire lot. Done early it buys 5–10 years before the next major capex event.
How much does parking lot repair cost?
Every lot is priced off a site walk — square footage of distress, patch depth, traffic loading, access window, and ADA scope all move the number. We don't publish per-square-foot rates because the same number misleads on a 200 sq ft pothole and a 4,000 sq ft alligator zone. Call (406) 309-SEAL for a written scope and number.
Repair or resurface — how do I know which I need?
Rule of thumb: if failures are localized and cover less than 25% of the lot, repair. If alligatoring is widespread, patches are stacking on patches, or the surface is oxidized through to gray, mill-and-overlay is the right move. If the lot is pumping water or settling unevenly, the sub-base has failed and reconstruction is on the table. We document which one you need in writing — not a guess.
How long do parking lot repairs last?
A properly saw-cut, full-depth hot-mix patch over sound sub-base lasts 7–10 years. Infrared patches last 5–8. Cold-patch is a 6-month bridge, not a fix. Crack seal lasts 3–5 years and should be renewed on a calendar. The variable is always sub-base — if water is in it, no surface repair lasts.
Can you repair in winter?
Cold-patch can be placed year-round as an emergency stopgap. Hot-mix patching needs ambient temps above ~40°F and dry conditions to bond properly, which in our territory means roughly April through October. We schedule winter emergency response, then convert to permanent hot-mix in spring.
Do you handle ADA compliance during repairs?
Yes. Any repair that touches stalls, access aisles, or ramps is brought to current ADA code — slope, width, signage, and surface — in the same mobilization. We don't leave a property exposed to a non-compliant restripe.
Do you offer warranties on parking lot repair?
Yes — written workmanship warranty on every patch, crack seal, and overlay. Terms vary by scope and are spelled out on the proposal. Sub-base or drainage failures outside the repair area are excluded; we'll flag those in writing before we start so there are no surprises.
What areas do you serve?
Montana, Idaho, eastern Washington, North Dakota, and South Dakota. Primary markets include Missoula, Bozeman, Kalispell, Billings, Great Falls, Helena, Boise, Coeur d'Alene, Spokane, Fargo, Bismarck, Sioux Falls, and Rapid City.
