Serving Longmont for Over 30 Years
Longmont is a working city, and its pavement shows it. Heavy truck traffic through the industrial corridor on Sunset Street, constant commercial activity along Main Street and Ken Pratt Boulevard, and residential driveways that cycle through Boulder County’s freeze-thaw seasons. We are a asphalt contractor in Longmont area for over 30 years. We know what it takes to build and maintain pavement that holds up here.
Whether you’re managing a commercial property in the Twin Peaks Mall corridor or replacing a driveway in Prospect or Renaissance, you’ll get a straight assessment and crew that builds it right.

Asphalt Services in Longmont
Parking Lot Paving
Longmont’s industrial properties along Sunset Street and the tech/commercial corridor near the airport see serious truck and forklift traffic that demands properly-built asphalt sections. Retail along Ken Pratt and Main Street needs surface quality that holds up to daily use and UV. We handle full parking lot paving for properties of all types, with asphalt depth and subgrade prep matched to your actual traffic load.
Parking Lot Sealcoating
Longmont’s Boulder County location means UV intensity and freeze-thaw cycles that age asphalt faster than most property owners account for. Commercial-grade sealcoating every two to three years is the most cost-effective maintenance call you can make. We crack seal before the sealant goes down and work with property managers to minimize disruption.
Asphalt Repair
Boulder County’s clay soils create movement under pavement that shows up as cracking, heaving, and pothole formation. We assess the actual cause before recommending a fix. See our asphalt repair page for what’s involved in different repair types.
Parking Lot Striping
We handle new lot layouts and restriping throughout Longmont, including ADA-compliant stalls, fire lanes, directional markings, and loading zone designations for industrial properties. Restriping is also one of the fastest ways to get more capacity out of an existing lot.
Driveway Paving
Longmont residential soils vary by neighborhood. Older areas near downtown and the St. Vrain corridor have more variable soil composition with potential organic content from historic agricultural use. Newer developments have more uniform clay profiles. We handle full driveway replacements and new installs with base conditions assessed before we start.
Driveway Sealcoating
Longmont’s climate puts real stress on residential asphalt. UV from the Boulder County sun exposure, freeze-thaw cycles, and snow removal all degrade driveways faster than metro areas. Driveway sealcoating every two to three years extends life significantly. We fill cracks before the sealant goes down.

How Enright Diagnoses Pavement Failure in Longmont
Longmont pavement fails for six main reasons, and the fix only holds if you treat the right one. Asphalt soaked by the St. Vrain floodplain needs a different repair than asphalt cracked by clay heave on higher ground. A contractor who patches both the same way will watch both fail within a season. We figure out what caused the damage before we tell you how to fix it.
St. Vrain Floodplain Saturation
Root Cause: Properties near the St. Vrain Creek and Left Hand Creek sit on a floodplain with a high water table. Even without a flood, water stays close to the surface and keeps the sub-base wet. Wet base means soft base, and soft base means cracking.
ENRIGHT SOLUTION
We rebuild the base with extra drainage and a deeper aggregate layer to handle the high water table. For lots with active drainage issues, we add a grading plan to move water off the slab.
Clay and Shale Heave
Root Cause: Most of Longmont sits on clay and shale soil. This soil swells when it gets wet and shrinks when it dries. The ground under your pavement can lift and drop two to four inches every season.
ENRIGHT SOLUTION
Sealcoat every two to three years to block the brine and rebuild your surface protection. If your pavement already shows brine damage, we mill and overlay the affected areas, then finish with a full sealcoat.
Magnesium Chloride Brine Corrosion
Root Cause: CDOT sprays magnesium chloride brine on Highway 119, I-25, and Main Street as the main de-icer. The brine sticks to tires and gets dragged onto your lot. It soaks deep into the asphalt binder and breaks it down over time.
ENRIGHT SOLUTION
Sealcoat every two to three years to block the brine and rebuild your surface protection. If your pavement already shows brine damage, we mill and overlay the affected areas, then finish with a full sealcoat.
Spring Thaw Base Failure
Root Cause: Longmont’s frost line runs about 36 inches deep. When it thaws from the top down in March and April, the base gets soaked and loses its strength for a few weeks. Cracks open up fast in that window.
ENRIGHT SOLUTION
We seal cracks in late spring once the sub-base firms back up. That keeps water out before the next freeze cycle hits and makes the damage worse.
Heavy Snow Load and Plow Damage
Root Cause: Longmont parking lots take a beating from heavy snow between November and March. Plow blades scrape the surface every time crews clear it. The worst damage shows up along curbs, gutters, and structures where blades scrape the most.
ENRIGHT SOLUTION
We repair the edges and do full-depth patching where plows have torn things up. Then we add traffic-grade striping built to survive multiple plow passes.
Freeze-Thaw Alligator Cracking
Root Cause: Longmont crosses 32°F more often than colder northern cities, which means more freeze-thaw cycles every year. Water seeps into unsealed cracks, freezes, expands about 9%, and slowly breaks the sub-base apart.
ENRIGHT SOLUTION
For small alligator-cracked sections, we do full-depth repair and rebuild the base underneath. For larger areas, we mill the surface and put down a fresh asphalt overlay.
What You Should Know About Paving in Longmont
Longmont’s soils are predominantly clay-based and expansive, especially in the western and central parts of the city. Properties near the St. Vrain Creek floodplain can have additional moisture concerns during wet seasons. Industrial properties with heavy equipment need heavier asphalt sections built to different specs than standard commercial work.
The City of Longmont requires permits for driveway construction and commercial paving projects. Stormwater management requirements apply to projects that increase impervious surface. We coordinate permit requirements before starting any project.
