The stretch along Three Notch Road and Great Mills Road sees consistent, high-volume traffic from early morning through late evening not the occasional weekend shopper, but hundreds of vehicles daily from defense contractor offices, retail businesses, and government-adjacent services. That kind of load accelerates surface wear faster than most contractors plan for. When the base prep is wrong or the asphalt spec is residential-grade instead of commercial, you start seeing failures within five to seven years instead of twenty.
Lexington Park’s climate adds another layer to this. The coastal proximity to the Patuxent River means higher humidity year-round, and winters here don’t stay frozen they fluctuate right around 32°F, which triggers freeze-thaw cycles repeatedly throughout the season. That’s actually more damaging than a sustained hard freeze, because water infiltrates micro-cracks, expands when it freezes, and forces them wider every time the temperature swings. A properly engineered lot with the right drainage design and commercial-grade hot-mix asphalt resists that pattern. One that cuts corners doesn’t.
When the work is done right, you’re looking at 15 to 25 years of serviceable life with a basic maintenance program. No recurring patch jobs every spring. No ADA violations from deteriorating accessible routes. No liability from potholes that have been ignored one season too long. Just a lot that does its job and reflects well on the property.
We’ve been operating in Maryland since 2011 14 years of freeze-thaw seasons, coastal humidity, and commercial paving projects across the state. We hold MHIC License #159766, carry a BBB A+ rating, and bring the kind of documentation that facility managers and property owners in St. Mary’s County need before a project moves forward.
That matters in Lexington Park more than most places. The buyers along the Route 235 corridor facility directors at defense contractor offices, commercial property managers, business owners serving the NAS Patuxent River workforce are accustomed to verifying credentials before they engage anyone. A verbal quote and a handshake don’t cut it in this market. We show up with a written proposal that specifies materials, thickness, base prep approach, scope, and timeline. Everything you need to make a confident decision.
From new asphalt parking lot installation to resurfacing, crack filling, sealcoating, and line striping including ADA markings it’s all handled under one contractor relationship. One call, one accountable team, no vendor juggling.
It starts with a free on-site assessment. Before any quote is written, we evaluate your existing surface, the subbase condition, drainage patterns, and how your lot is actually being used entry points, high-traffic lanes, loading zones, ADA routes. In Lexington Park, that drainage evaluation is especially important. The area’s high humidity and proximity to the Patuxent River mean standing water persists longer here than in drier inland markets, and a lot that doesn’t shed water properly will deteriorate faster regardless of how good the asphalt is.
From there, you get a written proposal with everything spelled out. If your project involves curb cuts, drainage connections, or work near Three Notch Road or Great Mills Road, St. Mary’s County’s Department of Public Works and Transportation requires a construction permit for right-of-way work and if the scope involves significant land disturbance, Maryland’s erosion and sediment control requirements apply. We handle the permitting process as part of the project, so you’re not left navigating county offices on your own.
Once work begins, the focus is on minimizing disruption. Most commercial lots on the Route 235 corridor can’t afford a full closure for a week. We use phased paving to keep portions of the lot accessible throughout the project, and we communicate curing timelines clearly typically 24 to 48 hours before light traffic, three to seven days before full commercial use. When the job is done, you’ll see the difference before you even step out of your car.

Whether you’re building a new parking lot from the ground up, resurfacing an aging lot that’s been patched one too many seasons, or putting a structured maintenance program in place, we cover the full lifecycle. New asphalt parking lot construction, overlay and resurfacing, crack filling, sealcoating, and parking lot line striping including ADA-compliant markings, directional arrows, fire lane designations, and van-accessible space layouts are all handled in-house.
A significant portion of the commercial parking lots along Three Notch Road and Great Mills Road were built during the BRAC-driven growth of the 1990s and early 2000s. That means a lot of those surfaces in Lexington Park are now 20 to 30 years old. Some have been maintained well. Many haven’t. If your lot is in that category cracked, faded, showing alligator patterns or persistent potholes the question isn’t whether it needs attention, it’s whether an overlay makes sense or whether full-depth replacement is the smarter long-term investment. That assessment is part of the free quote process.
For defense contractor office parks, government-adjacent commercial properties, and businesses serving the NAS Patuxent River workforce, ADA compliance isn’t a formality it’s a genuine legal and operational requirement. Federal first-violation fines reach $75,000. Every project we deliver is engineered with ADA compliance built in from the design stage, not retrofitted after the fact.
Commercial parking lot paving typically runs between $2.00 and $4.50 per square foot for new asphalt installation, depending on lot size, existing base condition, drainage requirements, and whether ADA layout work is included. For resurfacing an existing lot in reasonable condition, costs are generally lower. For a full tear-out and replacement, they run higher.
In Lexington Park specifically, drainage engineering tends to add meaningful value to the project scope. The area’s coastal humidity and proximity to the Patuxent River mean that standing water is a real and persistent issue on lots without proper grade and drainage design. Cutting that out of the budget to save on installation cost is one of the most common reasons lots fail prematurely. A written quote from us will break down exactly where your money is going and why no vague line items.
A properly installed commercial parking lot in Southern Maryland should last 15 to 25 years with a basic maintenance program. The key word is properly. That means commercial-grade hot-mix asphalt at the right thickness typically 3 to 5 inches for commercial use over a compacted aggregate base, with drainage engineered to move water off the surface quickly.
Lexington Park’s climate is particularly hard on asphalt that wasn’t built to handle it. Winters here fluctuate around the freezing point rather than staying consistently cold, which means freeze-thaw cycles repeat frequently throughout the season. Each cycle forces micro-cracks wider. Add in the elevated humidity from the Chesapeake Bay region and you have conditions that accelerate surface degradation faster than most inland Maryland markets. Sealcoating every two to five years and staying ahead of crack repair significantly extends the lifespan of any well-installed lot.
It depends on the scope of the work. For resurfacing or overlay work that stays entirely within your existing property boundary and doesn’t involve drainage connections or curb modifications, permits are often not required. But if your project involves any work within a county right-of-way which is common for lots along Three Notch Road or Great Mills Road that connect to those corridors St. Mary’s County’s Department of Public Works and Transportation requires a construction permit.
New parking lot construction that involves significant grading or land disturbance also triggers Maryland’s erosion and sediment control requirements, and any meaningful addition of impervious surface may require a stormwater management review especially given Lexington Park’s proximity to the Patuxent River and the Chesapeake Bay’s nutrient runoff regulations. Commercial properties within the Lexington Park Development District also fall under the LPDD Master Plan’s land use requirements. We handle the permitting process as part of the project scope, so you’re not left figuring this out on your own.
In most cases, yes. For commercial properties along the Route 235 corridor in Lexington Park defense contractor offices, retail centers, medical offices a full parking lot closure isn’t realistic. The approach we use is phased paving: dividing the lot into sections and completing one section at a time so a portion of the lot stays accessible throughout the project.
The specifics depend on your lot’s layout, size, and how your traffic flows. Entry and exit points need to stay functional, accessible parking spaces need to remain available in compliance with ADA requirements, and any phasing plan needs to account for how your tenants or employees actually use the space. That’s part of what gets worked out during the site assessment before the quote is written not something figured out on the fly once work starts. Curing timelines run 24 to 48 hours for light traffic and three to seven days before the surface is ready for full commercial use.
Resurfacing also called an overlay means a new layer of asphalt is applied over the existing surface. It works well when the underlying base is still structurally sound and the existing asphalt has surface-level deterioration: cracking, weathering, minor rutting. It’s less expensive than full replacement and extends the life of the lot by 8 to 15 years when done correctly.
Full replacement means the existing asphalt is removed, the base is re-graded and compacted, and new asphalt is installed from the ground up. This is the right call when the base has failed when you’re seeing deep cracking patterns that go all the way through the surface, significant drainage problems, or areas where the asphalt has completely separated from the base. Many of the commercial lots built along Three Notch Road during the 1990s BRAC expansion are now at the point where a site assessment is needed to determine which approach makes more sense. Overlaying a failed base just delays the inevitable and costs more in the long run.
In Maryland, any contractor performing paving or home improvement work is required to hold an MHIC license that’s the Maryland Home Improvement Commission license. You can verify any contractor’s license status directly through the Maryland Department of Labor’s online license lookup tool. It takes about 30 seconds and tells you whether the license is active, what it covers, and whether any complaints have been filed.
This matters in Lexington Park more than most markets. The paving industry has a documented problem with unlicensed crews particularly in spring who take deposits, do substandard work, and are gone before the first winter reveals the failures. The professional class in this community, shaped by years of working in federal contracting environments, already knows to verify credentials before engaging anyone. We hold MHIC License #159766 and a BBB A+ rating both publicly verifiable. If a contractor you’re considering can’t give you a license number to look up, that’s your answer.
