Parking Lot Sealcoating in Fargo, ND

Parking lot sealcoating spreads a protective sealer over a commercial, church or apartment lot with spray rigs and larger squeegee crews, and it matters to many owners here because so much of the city's asphalt sits in shared lots. About 56 percent of occupied housing units in Fargo are rented and only about a third of all units are detached houses, according to ACS 2019-2023 estimates, so most residents park on a lot rather than a private drive. Those lots take plow blades, tire-borne grit and heavy snow piles every winter. A coat every two to four years, laid over sealed cracks, protects the binder and gives fresh paint a clean base; pair it with line striping.

The practical challenge on a lot is keeping it open. The work is usually done in sections, with residents or customers shifted from one half to the other, and SealMaster's instruction is a full day of curing after the last coat before cars come back to a section. That clock is easiest to meet in July and August, when Hector nights seldom fall to 50 degrees. Its specification also calls for two coats, plus a third where traffic concentrates: entrances, exits and drive lanes, where turning tires wear the surface fastest.

Paved area carries a cost here beyond upkeep. Since January 2019, Fargo has billed non-residential properties for storm water based on their total area and impervious area, while single-family homes pay a common monthly charge. Sealcoating does not change a lot's footprint, so it leaves that charge alone; adding pavement can raise it. The same storm water program forbids pouring oil, paint or similar materials into storm drains, which carry runoff toward the Red River, so a crew should keep sealer and rinse water out of the lot's catch basins.

Product choice has a local environmental side. USGS measurements find between 35,000 and 200,000 mg of PAHs per kilogram of coal-tar-based sealcoat, around a thousand times the level in asphalt-based products, and abraded particles leave the pavement in runoff, on the wind and in tire treads. North Dakota does not ban it. Minnesota does, statewide, so parking lot sealcoating in Moorhead or Dilworth has to use asphalt emulsion or acrylic. A property manager with lots on both banks can keep specifications simple by calling for a non-coal-tar product at every site.

Winter leaves marks on a lot that a driveway never sees. Hector averages about 99 days a year when snow covers the ground an inch deep or more, and plow piles sit on the same corner islands and end stalls for much of that time. Meltwater from those piles runs across the pavement on every thaw, so those corners crack and ravel first. Pushing snow to a spot where it can drain toward an inlet, instead of across the lot, is worth settling with the plow contractor, and the pile corners deserve an extra crack pass before each coat.
