Faded, brittle asphalt doesn't just look neglected; it's actively losing value. UV exposure, water intrusion, vehicle fluids, and daily traffic break down your pavement's surface layer over time. Cracks form, the subgrade weakens, and what could have been a low-cost maintenance cycle turns into a major capital project. Parking lot sealcoating applies a protective asphalt emulsion barrier that blocks deterioration before it compounds, keeping your pavement flexible and intact between heavier service cycles.
Empire Parking Lot Services delivers professional asphalt parking lot sealcoating for commercial, industrial, and multi-family properties across Southern California. Since 2008, we've built our reputation on doing this work the right way, no shortcuts, no overselling.
Parking lot sealcoating adds a protective barrier between your asphalt and the elements that wear it down. It is not a cosmetic treatment. The process applies a thin layer of asphalt emulsion over your existing surface to block the UV exposure, water intrusion, and chemical damage that shorten your pavement's life. That barrier is what keeps a well-maintained lot performing years longer than one left unprotected.
UV rays are one of the biggest threats to asphalt in Southern California. Prolonged sun exposure dries out the asphalt binder that holds your pavement together, and that oxidation makes the surface brittle and prone to cracking. A professional sealcoat application replaces the fine particles and surface oils lost to UV exposure, keeping your asphalt flexible and crack-resistant for longer.
Water intrusion causes the other major category of damage. Once water penetrates the surface through open pores or hairline cracks, it erodes the sub-base underneath your pavement. That erosion leads directly to soft spots, potholes, and structural failure. In Southern California, irrigation runoff is a frequent culprit, especially on properties with landscaping adjacent to paved areas. Parking lot sealing waterproofs those surface pores and blocks chemical breakdown from gasoline, oil, antifreeze, and other vehicle fluids that eat away at asphalt bonds over time.
Beyond the structural protection, you notice a visible difference on your property after a properly applied sealcoat treatment:

Every parking lot sealcoating project at Empire follows a structured process built around preparation, quality materials, and minimal disruption to your tenants and their operations. Most commercial sealcoating projects are completed in a single day, though properties requiring multiple services may be phased across separate mobilizations to maintain quality. Our crews have refined this process across thousands of Southern California projects to keep your work on schedule and on budget.
Empire starts every job with thorough surface preparation. Our crews clean the entire lot using high-powered blowers, wire brushes, and industrial brooms to remove dirt, loose aggregate, and debris. Oil spots get special attention. We scrape and burn off each one before sealcoat is applied, so the sealcoat bonds directly to clean asphalt rather than sitting on top of contaminated areas.
Cracks wider than a hairline get addressed before any sealcoat goes down. Our team evaluates the surface and recommends crack repair and sealing when needed. Skipping this step leads to peeling, product failure, and wasted money. We do not take that shortcut, and you should not accept it from any paving company that does.
We apply one to two coats of premium asphalt emulsion using squeegee or spray methods, depending on your lot's size, layout, and surface conditions. The emulsion is formulated for durability in high-traffic commercial environments. Empire selects the manual or machine method that delivers the most consistent coverage for your specific lot.
Before any sealcoat goes on, our crew barricades work areas with string line and flagging tape for maximum visibility. We notify your tenants and building occupants in advance and, if needed, provide diagrams of scheduled work zones so that daily operations continue with minimal interruption. After the final coat, our team cleans up completely. All your tenants see the next morning is a freshly sealed lot with a rich, uniform black finish ready for new parking lot striping.
Parking lot seal coating typically requires 24 to 48 hours of curing time before vehicle traffic can resume. Temperature and humidity directly affect how quickly the asphalt emulsion sets, so Empire schedules every application when conditions support proper drying.
Once cured, your lot is ready for striping and regular use. The restored dark surface makes traffic lines, fire lanes, and ADA upgrades significantly more visible, improving both safety and appearance for everyone who uses your property.
Timing plays a direct role in how well your parking lot sealcoating application performs and how long it lasts. A clear parking lot maintenance schedule protects your investment without over-applying product that can build up and peel.
New asphalt and recent overlays need 4 to 6 months of curing before the first sealcoat application. This extended cure time allows volatile oils in the fresh asphalt to fully release, providing the sealant with a proper surface to bond to. On smaller patching projects, we recommend waiting 45 to 60 days before sealing.
For established lots, sealcoating parking lot surfaces every 3 to 5 years keeps the protective layer intact without causing buildup. Your lot's condition and traffic volume determine the exact interval. High-traffic zones like retail entrances, drive-throughs, and loading areas may need the shorter end of that cycle. Empire builds a maintenance timeline based on your property's specific traffic patterns and sun exposure.
Southern California's mild climate allows parking lot sealcoating throughout much of the year. The ideal conditions are daytime temperatures above 50°F paired with low humidity. Spring and fall tend to deliver the most consistent results, though plenty of projects move forward successfully in the warmer months.
Empire monitors weather conditions closely before and during every project. If rain, excessive humidity, or a drop in temperature threatens adhesion or curing quality, we reschedule. Getting your project done right matters more than sticking to a calendar date.
Parking lot sealing is one of the lowest-cost preventive maintenance services available for commercial asphalt. Project pricing depends on your lot's square footage, surface condition, and the amount of prep work needed before sealcoat goes down. Every property is different, so Empire provides a detailed estimate based on a site assessment of your specific lot.
You will know exactly what your project costs before any work begins. No hidden fees, no surprises.
Asphalt parking lot sealcoating fills micro-cracks early, before water can reach the sub-base and escalate into potholes or structural failure. That proactive approach keeps your total pavement budget lower and more predictable across a 10-to-15-year pavement lifecycle. You spend less per year on maintenance and avoid the kind of compounding damage that turns small issues into major capital projects.
Sealcoating is one piece of a broader parking lot maintenance strategy. The table below compares it to other common services so you can understand when your lot needs preventive care, targeted repairs, or a more involved solution.
