Excavation for a new home foundation on Long Island typically runs between $5,000 and $20,000 for a standard residential project, with most jobs landing somewhere in the $8,000–$12,000 range. The price depends on the foundation size and depth, soil conditions, site access, whether rock or groundwater is encountered, and where the excavated material has to go. A complicated lot can push well above that range; a simple, flat site can come in below it.
What goes into a real driveway price?
A proper driveway installation isn’t just laying asphalt — it’s a layered system, and shortcuts at any layer show up later as cracks, sinkholes, and standing water. A real estimate includes:
- Excavation and prep — removing old material, grading, and shaping the base
- Compacted base — typically 4–8 inches of crushed stone, properly compacted
- Asphalt layers — usually a 2-inch base course and a 1-inch top course, sometimes more for heavy use
- Edge work — clean transitions to street, lawn, and walkways
- Disposal — hauling the old material if you’re replacing an existing driveway
What drives the price up?
A simple 2-car driveway on flat ground with a good existing base is the cheapest scenario. Things that push the price up include longer or wider driveways, sloped or hillside terrain, soft or wet subsoil that needs additional excavation, removing a thick old concrete driveway, special edging like Belgian block (which can add several thousand on its own), and decorative finishes.
New install vs. resurfacing
If your existing asphalt is structurally sound but tired-looking — surface cracking, faded color, minor wear — resurfacing (also called an overlay) is typically 30–50% cheaper than a full tear-out. But resurfacing only works if the base underneath is solid. If the existing driveway has deep cracks, sinking spots, or visible base failure, overlaying it just hides the problem until it cracks through again.
Long Island-specific factors
Long Island freeze-thaw cycles are hard on asphalt. A driveway installed with a thin base or skipped layers will start showing cracks within a few winters. Properly compacted base and adequate asphalt thickness are what separate a 5-year driveway from a 20-year driveway. Local soils also matter — some areas have soft fill that requires extra excavation and base depth.
How DLI installs driveways
DLI Contracting handles driveways as part of full-scope site work — meaning the same crew that prepares the base also lays the asphalt, ensuring nothing gets skipped at the layer where it matters most. For most residential driveways, that’s a properly compacted base topped with two lifts of asphalt, finished with clean edges. We also handle resurfacing, sealcoating, and crack repair on existing driveways when full replacement isn’t needed.
