Driveway repair in Southern Maryland costs $300 to $3,000 in 2026, and driveway resurfacing costs $2,000 to $8,000, depending on the material, the size of the driveway, and the extent of the damage. A full driveway replacement, tearing out the old surface and installing new, runs $3,000 to $15,000 or more. Most homeowners in Calvert, St. Mary's, and Charles County pay $1,000 to $4,000 for repairs and patching, or $3,000 to $6,000 for a full resurface of a two-car asphalt driveway.
Fall is the best time to address driveway problems in Southern Maryland. The paving season runs from late March through November, asphalt plants shut down when temperatures drop below 40 to 50 degrees, and concrete does not cure well below 50 degrees. If your driveway has cracks, potholes, or surface deterioration now, fixing it in September or October means the repair cures before winter. Leaving those cracks open through winter means water fills them, freezes, expands, and turns a $200 crack repair into a $2,000 section replacement by spring. Southern Maryland winters bring 15 to 25 freeze-thaw cycles per year, each one pushes water deeper into existing cracks and pushes those cracks wider.
Here is what driveway repair, resurfacing, and replacement cost in Southern Maryland, what each option involves, and how to decide between repair, resurfacing, and full replacement.
Driveway Cost Summary by Material and Service
| Service | Asphalt | Concrete | Gravel |
|---|---|---|---|
| Crack repair | $100 to $500 | $150 to $600 | N/A |
| Pothole repair | $100 to $400 per hole | $200 to $600 per hole | $100 to $300 (regrading) |
| Section replacement | $500 to $2,000 | $800 to $3,000 | N/A |

| Full replacement | $3,000 to $10,000 | $5,000 to $15,000 | $1,000 to $4,000 |
Asphalt Driveway Repair and Resurfacing
Asphalt is the most common driveway material in Southern Maryland, it is less expensive than concrete, tolerates the region's freeze-thaw cycles better than concrete when properly maintained, and can be repaired and resurfaced without full replacement. The trade-off is that it requires more maintenance than concrete and has a shorter lifespan.
Asphalt Crack Repair: $100 to $500
Cracks in asphalt driveways are inevitable. Asphalt is a flexible material that expands and contracts with temperature, and over time that movement creates cracks, typically starting as hairline cracks that widen into 1/4-inch to 1-inch cracks over several years.
Crack filling ($100 to $300 for a typical driveway): hot rubberized crack filler is applied to cracks up to about 3/4 inch wide. The filler bonds to both sides of the crack, remains flexible, and prevents water from penetrating. This is the most common and most cost-effective asphalt maintenance. A homeowner with a caulk gun and a jug of cold-pour crack filler from the hardware store can handle hairline cracks for $20 to $50 in materials.
Crack sealing ($200 to $500): for wider cracks (3/4 inch to 1-1/2 inches) or alligator cracking (a network of interconnected cracks that resembles alligator skin), the cracks are cleaned, sometimes routed (a router cuts a uniform channel), and filled with hot-pour sealant. Crack sealing is more durable and longer-lasting than crack filling.
When cracks mean more than surface damage: alligator cracking, a pattern of interconnected cracks forming irregular blocks, indicates structural failure in the asphalt base, not just surface wear. Filling or sealing alligator cracks buys time but does not fix the problem. The underlying base has failed (from water infiltration, poor original installation, or inadequate base thickness), and the affected area will need to be cut out and rebuilt or the entire driveway will need resurfacing or replacement.
Asphalt Pothole Repair: $100 to $400 Per Hole
Potholes form when water penetrates the asphalt surface (through cracks), erodes the gravel base underneath, and the unsupported asphalt above collapses under vehicle weight. They get worse quickly, once a pothole forms, every vehicle that drives over it breaks the edges further and every rain fills it with more water.
Cold patch ($100 to $150 per hole): a temporary repair using bagged cold-mix asphalt available at hardware stores. The pothole is cleaned, filled with cold patch material, and compacted. Cold patch is not a permanent repair, it shrinks, cracks, and loosens over time, typically lasting 1 to 3 years. It is a reasonable stopgap if you are planning a resurface or replacement within a year or two.
Hot patch (infrared or saw-cut) ($200 to $400 per hole): the area around the pothole is cut out to a clean, squared edge (using a saw or infrared heater that softens the surrounding asphalt), the base is repaired or compacted, and new hot-mix asphalt is applied and compacted flush with the surrounding surface. Hot patching is a permanent repair that integrates with the existing surface.
Asphalt Resurfacing (Overlay): $2,000 to $6,000
Resurfacing, also called an overlay, is a new layer of hot-mix asphalt (typically 1.5 to 2 inches thick) applied directly over the existing driveway surface. Resurfacing is the middle ground between patching and full replacement: it gives you a new, smooth, black surface at roughly half the cost of tearing out and rebuilding.
Cost by driveway size:
| Driveway Size | Area (approx.) | Resurfacing Cost |
|---|---|---|
| Single car (10 x 20 ft) | 200 sq ft | $1,000 to $2,000 |
| Two car (20 x 20 ft) | 400 sq ft | $2,000 to $3,500 |
| Two car with apron (20 x 35 ft) | 700 sq ft | $2,500 to $5,000 |
| Large (20 x 50 ft or more) | 1,000+ sq ft | $4,000 to $6,000+ |
Resurfacing costs $3 to $7 per square foot installed in Southern Maryland, depending on the thickness of the overlay, the condition of the existing surface (more prep work on a heavily damaged surface), and access for the paving equipment.
Resurfacing is a good option when:
- The existing asphalt is structurally sound (the base is intact and stable) but the surface is worn, faded, and has widespread minor cracking
- The driveway has moderate cracking but no alligator cracking or major structural failure
- The existing surface is relatively flat and drains properly
- The driveway is 10 to 15 years old and showing its age but has not failed
Resurfacing is not a good option when:
- The base has failed (alligator cracking, soft spots, areas that flex when you walk on them)
- The driveway has major drainage problems (standing water, water flowing toward the house or garage)
- The existing surface has heaved or settled unevenly by more than 1 to 2 inches, an overlay follows the contours of the surface below it, so if the old surface is wavy, the new surface will be wavy
- The driveway has already been resurfaced once, adding a third layer creates excessive height at the garage door transition and may cause drainage problems
Asphalt Sealcoating: $200 to $800
Sealcoating is not a repair, it is preventive maintenance. A thin, coal-tar or asphalt-based emulsion is applied to the surface to protect the asphalt from UV degradation, water penetration, and chemical damage (oil and gas spills). It also restores the dark black appearance.
Cost: $0.15 to $0.40 per square foot, or $200 to $800 for a typical two-car driveway. Most sealcoating companies quote by the job, not by the square foot.
Frequency: every 2 to 3 years. A newly paved or resurfaced driveway should not be sealcoated for the first 6 to 12 months, the asphalt needs time to fully cure and the volatile oils need to evaporate before sealing the surface.
The maintenance math. Sealcoating every 2 to 3 years at $300 to $500 per application extends the life of an asphalt driveway by 5 to 10 years. Over a 30-year period, a homeowner who sealcoats regularly may spend $3,000 to $5,000 on sealcoating and get 25 to 30 years out of the driveway before replacement. A homeowner who never sealcoats may need to resurface at year 12 to 15 and replace at year 18 to 22. The sealcoating investment typically saves $5,000 to $10,000 in deferred resurfacing and replacement costs.
Asphalt Driveway Replacement: $3,000 to $10,000
A full replacement removes the old asphalt surface (and often the gravel base below it), recompacts or rebuilds the base, and installs a new asphalt surface.
Cost by driveway size:
| Driveway Size | Area (approx.) | Replacement Cost |
|---|---|---|
| Single car (10 x 20 ft) | 200 sq ft | $1,500 to $3,000 |
| Two car (20 x 20 ft) | 400 sq ft | $3,000 to $5,000 |
| Two car with apron (20 x 35 ft) | 700 sq ft | $4,000 to $7,000 |
| Large (20 x 50 ft or more) | 1,000+ sq ft | $6,000 to $10,000+ |
Replacement costs $7 to $13 per square foot installed, which includes demolition and removal of the old surface, base grading and compaction, and a new asphalt surface (typically 2 to 3 inches of compacted hot-mix asphalt over 4 to 8 inches of compacted gravel base).
The base matters more than the surface. The most common reason asphalt driveways fail prematurely is an inadequate base, too thin, improperly compacted, or built on unprepared soil. In Southern Maryland's clay soil, the base is critical because clay expands and contracts with moisture, and that movement pushes up through a thin or poorly compacted base. A properly built driveway in this region needs a minimum of 6 inches (8 inches is better) of compacted #57 or #21A gravel base, plus 2 to 3 inches of compacted asphalt. A driveway built with 2 inches of asphalt on 4 inches of uncompacted gravel over clay, which is what cheap installations look like, will crack and fail within 5 to 8 years.
Concrete Driveway Repair and Resurfacing
Concrete driveways are more expensive than asphalt but last longer and require less ongoing maintenance. They are common in newer subdivisions in Waldorf, La Plata, and White Plains, and in custom homes throughout the tri-county area.
Concrete Crack Repair: $150 to $600
Concrete cracks for the same reason asphalt does, expansion, contraction, settling, and tree root pressure, but concrete is rigid, so cracks tend to be more visible and more disruptive to the surface.
Crack filling ($150 to $400): concrete crack filler (polyurethane or epoxy) is applied to cracks up to 1/2 inch wide. The filler is flexible enough to accommodate minor movement and prevents water from penetrating to the base. Color-matched filler is available but rarely matches perfectly, repaired cracks are visible.
Crack injection ($300 to $600 per crack): for deeper or wider cracks, polyurethane foam or epoxy is injected under pressure to fill the crack from the bottom up. This is a more thorough repair than surface filling and works on cracks that extend through the full thickness of the slab.
Concrete Section Replacement: $800 to $3,000
When a concrete slab section has heaved, sunk, or is severely cracked, the section is cut out with a concrete saw and replaced with a new pour. Concrete driveways are typically poured in sections separated by control joints (the lines scored or cut into the surface), these joints are where the slab is designed to crack if it is going to crack, and they make section replacement straightforward. The damaged section is cut out at the control joints, the base is re-graded and compacted, and new concrete is poured and finished.
Cost: $8 to $15 per square foot for the replacement section. A typical 4x10-foot section costs $800 to $1,500 including demolition, base repair, pour, and finishing. The new section will not match the color and aging of the existing driveway for 1 to 2 years, new concrete is lighter than aged concrete.
Concrete Mudjacking and Polyleveling: $500 to $2,000
When concrete slabs have sunk (settled below the adjacent sections) but are otherwise intact, they can be lifted back to level without replacement.
Mudjacking ($500 to $1,200): small holes are drilled through the sunken slab, and a mixture of cement, sand, and water (slurry) is pumped under the slab to fill voids and lift it back to level. The holes are patched with concrete. Mudjacking is effective, affordable, and lasts 5 to 10 years. The slurry is heavy, which can cause additional settling on weak soil.
Polyleveling (foam injection) ($800 to $2,000): similar process, but polyurethane foam is injected instead of slurry. The foam expands to fill voids and lift the slab, then hardens within minutes. Polyleveling is lighter than mudjacking (reducing the risk of additional settling), cures faster, and is more precise. It costs more per application but is the preferred method for slabs over problem soil, and Southern Maryland's clay qualifies.
Concrete Resurfacing: $3,000 to $8,000
Concrete resurfacing applies a thin (1/8-inch to 1/4-inch) polymer-modified cement overlay to the existing concrete surface. The overlay bonds to the existing slab and creates a new, smooth, uniform surface. It can be tinted, stamped, or textured to change the appearance of the driveway.
Cost: $3 to $10 per square foot, depending on the finish (plain smooth is cheapest; stamped, stained, or textured is more). A two-car driveway (400 to 700 square feet) costs $3,000 to $7,000 for a resurfaced finish.
Resurfacing works when: the existing concrete is structurally sound but cosmetically worn, surface spalling, minor crazing, discoloration, and staining. It does not work on slabs with major structural cracks, heaved sections, or a failed base. The overlay is thin and follows the shape of the existing surface, structural problems below telegraph through to the surface within a year.
Concrete Driveway Replacement: $5,000 to $15,000
A full concrete driveway replacement demolishes the old slab, re-grades and compacts the base, and installs a new concrete slab (typically 4 inches thick for residential driveways, 5 to 6 inches for heavy vehicles or RVs).
Cost by driveway size:
| Driveway Size | Area (approx.) | Replacement Cost |
|---|---|---|
| Single car (10 x 20 ft) | 200 sq ft | $2,500 to $4,000 |
| Two car (20 x 20 ft) | 400 sq ft | $5,000 to $7,000 |
| Two car with apron (20 x 35 ft) | 700 sq ft | $6,000 to $10,000 |
| Large (20 x 50 ft or more) | 1,000+ sq ft | $10,000 to $15,000+ |
Replacement costs $10 to $18 per square foot installed, including demolition, base preparation, concrete pour, control joint cutting, and finishing. Add $2 to $5 per square foot for decorative finishes (exposed aggregate, stamped patterns, colored concrete).
Gravel Driveway Repair and Maintenance
Gravel driveways are common in rural areas of Calvert, St. Mary's, and Charles County, particularly on properties set back from the road with long drives. They are the least expensive option to install and the most maintenance-intensive.
Gravel Driveway Regrading: $500 to $2,000
Over time, gravel driveways develop ruts from tire tracks, lose material from rain washout, and develop potholes. Regrading, using a box blade or motor grader to redistribute the existing gravel into a smooth, properly crowned surface, is the primary maintenance.
Cost: $500 to $1,500 for a typical residential driveway (up to 500 linear feet). Longer driveways or driveways that require significant material redistribution cost more. Many homeowners with tractors and box blades handle this themselves.
Frequency: once or twice a year, more if the driveway is on a grade or in an area with heavy rain runoff.
Adding New Gravel: $1,000 to $4,000
A gravel driveway loses material every year, rain washes it off the edges, vehicles push it to the sides, and the base compresses. Adding new stone every 2 to 5 years maintains the surface depth and ride quality.
Cost by driveway size and stone depth:
| Driveway Length | Width | New Stone (2 inches) | New Stone (4 inches) |
|---|---|---|---|
| 50 ft | 12 ft | $500 to $800 | $800 to $1,400 |
| 100 ft | 12 ft | $800 to $1,400 | $1,400 to $2,500 |
| 200 ft | 12 ft | $1,400 to $2,500 | $2,500 to $4,000 |
Stone type matters. The standard for a driveway top layer in Southern Maryland is #57 stone (3/4-inch to 1-inch crushed stone) or CR-6 / #21A (a blend of crushed stone and stone dust that compacts into a firm surface). #21A is the better choice for driveways because the stone dust fills the gaps between the larger stones and locks them together, creating a surface that is smoother, firmer, and more resistant to ruts than open-graded #57 alone.
Gravel Driveway Replacement: $1,000 to $4,000
A full rebuild, stripping the old surface, re-grading the subbase, installing geotextile fabric (which prevents the gravel from migrating into the clay soil below), and laying fresh stone in lifts, costs $1,000 to $4,000 for a standard residential driveway.
The geotextile fabric detail. In Southern Maryland's clay soil, gravel placed directly on clay gradually sinks into it, the stones press into the soft clay, the clay oozes up between the stones, and within a few years the drive is half gravel and half mud. A layer of non-woven geotextile fabric between the clay and the gravel base prevents this. It is a $0.20 to $0.50 per square foot addition that doubles the useful life of the gravel layer. If you are rebuilding a gravel driveway on clay, insist on the fabric.
The Southern Maryland Driveway Problem: Clay, Water, and Freeze-Thaw
Every driveway material in this region faces the same three challenges.
Clay Soil Movement
The Coastal Plain clay soils that dominate Calvert, St. Mary's, and Charles County are expansive, they swell when wet and shrink when dry. This seasonal volume change creates heaving (upward movement when wet) and settling (downward movement when dry) that shifts the base under the driveway. In asphalt, this movement creates cracks and undulations. In concrete, it creates cracked and heaved slabs. In gravel, it creates ruts and soft spots.
The mitigation: a properly compacted, sufficiently thick aggregate base absorbs the soil movement before it reaches the driveway surface. This is why base thickness and compaction quality are the most important factors in driveway longevity, regardless of the surface material. A 6- to 8-inch compacted gravel base over geotextile fabric on properly graded clay subsoil is the standard for Southern Maryland driveways.
Water and Drainage
Water is the enemy of every driveway. It softens the base, erodes gravel, penetrates asphalt cracks and undermines the base from below, and causes the freeze-thaw damage described above. Proper drainage, grading the driveway so water runs off the sides and away from the garage, and installing swales or drains where necessary, is the single most important factor in driveway longevity.
A driveway that puddles is a driveway that is failing. Standing water indicates either insufficient crown (the slight convex curve from center to edges that sheds water to the sides), inadequate slope, or a drainage blockage at the edge. Every driveway repair or resurfacing project should address drainage, otherwise you are resurfacing a driveway that will fail the same way, for the same reason, on the same schedule.
Tree Root Damage
Southern Maryland properties are heavily treed, oaks, tulip poplars, sweetgums, and pines, many with aggressive root systems that extend 20 to 50 feet from the trunk. Roots growing under a driveway lift and crack the surface from below. This is a common issue in established neighborhoods in Dunkirk, Huntingtown, Owings, Leonardtown, and California where mature trees line the driveways.
Options when roots are the cause:
- Root pruning and barrier installation ($300 to $1,500): the offending roots are cut (by a certified arborist who can assess whether root removal will harm the tree), and a root barrier (a rigid plastic or metal sheet buried vertically 18 to 24 inches deep) is installed between the tree and the driveway to redirect future root growth. This works for small to medium roots, large structural roots cannot be cut without risking the tree.
- Rerouting the driveway around the root zone: expensive and not always possible.
- Accepting the damage and patching periodically: for a mature tree that you do not want to risk, patching the driveway surface as roots lift it may be the practical choice.
- Tree removal ($500 to $3,000): the last resort. Removes the cause permanently but loses the tree.
Repair, Resurface, or Replace: How to Decide
| Condition | Repair | Resurface | Replace |
|---|---|---|---|
| A few isolated cracks, no base failure | Yes | No | No |
| A pothole or two | Yes | No | No |
| Widespread surface cracking, base still solid | Maybe (expensive) | Yes | Maybe |
| Alligator cracking in asphalt (base failure) | No (temporary only) | No | Yes |
| Sunken or heaved concrete slabs | Mudjack/polylevel | No | If widespread |
| Surface worn, faded, minor cracking throughout | No | Yes | No |
| Standing water, drainage problems | Fix drainage first | Only if drainage is fixed | Only if drainage is fixed |
| Driveway is 20+ years old with multiple problems | No | Maybe (gets 8 to 10 more years) | Yes (long-term solution) |
The cost comparison over 30 years:
For a standard two-car asphalt driveway (400 to 700 square feet):
- Sealcoat every 3 years + repair cracks as they appear: $6,000 to $10,000 over 30 years. Driveway lasts 25 to 30 years before replacement.
- No maintenance, resurface once, replace once: $10,000 to $16,000 over 30 years.
- No maintenance, replace twice: $12,000 to $20,000 over 30 years.
Regular maintenance wins. A $300 sealcoat every three years and a $200 crack repair when cracks appear defers a $6,000 replacement by a decade.
What to Look for in a Paving Contractor
Driveway work attracts traveling crews and low-ball bids, particularly asphalt, where a truck of hot mix and a roller can produce a driveway that looks great on day one and fails within two years because the base was inadequate.
Get three quotes. Not one, not two, three. Compare not just price but scope, what base thickness are they specifying? How many inches of asphalt? What type of stone for the base? Are they including compaction? Will they fix grading and drainage?
Ask about the base. A contractor who does not discuss the base and its preparation is a contractor who is planning to skip it. The base is the structural foundation of the driveway. Ask specifically: how many inches of compacted aggregate, what type of stone, will they compact with a vibratory roller, will they install geotextile fabric over the clay subsoil.
Get it in writing. The quote should specify the base thickness and material, the asphalt or concrete thickness, the total area, the drainage plan, the start and completion dates, and the warranty. Verbal promises about base thickness disappear the moment the crew arrives.
Check the MHIC license. Any contractor performing home improvement work in Maryland, including driveway installation and repair, must hold a Maryland Home Improvement Commission (MHIC) license. Ask for the number and verify it at the MHIC website.
Beware of the truck-is-in-your-neighborhood deal. "We just finished a job nearby and have leftover asphalt, we can do your driveway today at a discount." This is a classic asphalt scam. The "discount" gets a thin layer of asphalt over an unprepared base, and the crew is gone by the time the problems appear. Legitimate paving contractors schedule work days or weeks in advance, prepare the base properly, and do not cold-call with leftover material.
Frequently Asked Questions
How much does it cost to repair a driveway in Southern Maryland? Minor crack repairs cost $100 to $500. Pothole repairs cost $100 to $400 per hole. Section replacement costs $500 to $3,000 depending on material and area. Most homeowners pay $500 to $2,000 for common repairs on asphalt or concrete driveways.
How long does an asphalt driveway last? With proper maintenance (sealcoating every 2 to 3 years, crack repair as needed), an asphalt driveway lasts 20 to 30 years in Southern Maryland. Without maintenance, expect 12 to 18 years before resurfacing or replacement is needed. The base quality, drainage, and maintenance frequency are the biggest lifespan factors.
How long does a concrete driveway last? A properly installed concrete driveway lasts 25 to 40 years with minimal maintenance. Concrete is more durable than asphalt and does not require sealcoating, but it costs more upfront and is more expensive to repair. Cracks in concrete are also more visible and more difficult to repair cosmetically than cracks in asphalt.
Is resurfacing worth it or should I just replace the driveway? Resurfacing is worth it when the existing base is structurally sound and the surface is the problem. It costs roughly half of what a full replacement costs and extends the driveway's life by 8 to 15 years. Replacement is the better choice when the base has failed, when there are major drainage problems, or when the driveway has already been resurfaced once.
When is the best time to pave or resurface a driveway? Late spring through early fall (May through October) is the paving season in Southern Maryland. Asphalt needs ambient temperatures above 50 degrees to compact properly, and warmer temperatures produce better compaction and adhesion. Concrete can be poured in temperatures above 50 degrees. Fall (September and October) is an ideal time, the weather is warm enough for good paving conditions, the holiday schedule has not started, and the driveway has the mild fall months to cure before winter.
Do I need a permit for driveway work? In most cases, resurfacing or repairing an existing driveway does not require a permit. A new driveway installation or a driveway expansion that changes the impervious surface area may require a grading permit or stormwater management compliance, particularly in the Chesapeake Bay Critical Area (which covers much of the shoreline in Calvert and St. Mary's County). Check with your county planning and zoning department, or ask your contractor to handle it.
Should I seal my asphalt driveway? Yes. Sealcoating every 2 to 3 years is the single most cost-effective maintenance investment for an asphalt driveway. It protects against UV degradation, water penetration, and chemical damage, extends the driveway's life by 5 to 10 years, and costs $200 to $800 per application. Wait 6 to 12 months after paving or resurfacing before the first sealcoat, and apply on a dry day with temperatures above 50 degrees.
