What buyers typically pay for concrete core drilling depends on hole size, drill depth, concrete hardness, and access. The cost to core drill concrete combines labor, equipment, and any required permits or disposal fees, with price swings driven by diameter and location. This guide gives a practical, low–average–high range in USD and explains the main cost drivers.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Core hole (4″ diameter, 6″ deep typical) | $120 | $180 | $320 | Includes basic cutting and dust control |
| Per additional hole | $100 | $160 | $280 | Same diameter, shallow depths |
| Labor (hourly, licensed tech) | $60 | $85 | $140 | Typically 1–3 hours per hole depending on access |
| Equipment rental & consumables | $30 | $60 | $120 | Core drill rig, diamond bits, coolant |
| Permits & inspections | $0 | $60 | $250 | Required in some jurisdictions or for critical work |
| Delivery / disposal | $20 | $50 | $150 | Dust containment and debris removal |
| Contingency | $20 | $40 | $100 | Unforeseen cuts or rework |
| Taxes | $0 | $15 | $40 | Depends on locality |
Assumptions: region, access, concrete composition, drill depth, and hole count vary; prices reflect typical residential or light commercial work.
Overview Of Costs
The total project price combines holed work with labor and logistics, usually across a few items rather than a single line item. For planning, consider a basic scenario with one 4″ hole, 6″ deep, in accessible space. A realistic total range is $120-$320 per hole, with common midpoints around $180-$200 when a single hole is needed and access is straightforward. If multiple holes are required, per-hole costs generally decrease slightly due to shared setup, but mobilization may add an incremental delivery charge.
Cost Breakdown
To help buyers forecast, the following table separates major cost elements and typical ranges. The table shows totals and per-hole estimates, plus a short note on when each cost factor matters most.
| Column | Low | Average | High | Typical Scenario |
|---|---|---|---|---|
| Materials | $0 | $0 | $0 | Core bit wear included in equipment; no separate material costs for standard cores |
| Labor | $60 | $85 | $140 | Licensed operator; 1–2 hours per hole |
| Equipment | $30 | $60 | $120 | Diamond core bit, vibration mitigation, hoses |
| Permits | $0 | $60 | $250 | Mandatory in some jurisdictions or for certain projects |
| Delivery/Disposal | $20 | $50 | $150 | Debris removal and dust control included |
| Contingency | $20 | $40 | $100 | Extra cuts or corrections |
| Taxes | $0 | $15 | $40 | State and local sales tax |

Factors That Affect Price
Several variables cause price variance, including hole diameter, depth, concrete composition, and access. A 4″ core requires less time than a 6″ core, and deeper drilling or high-strength concrete can double labor hours. The cost driver that most often shifts totals is the hole count and the time needed to set up dust containment and safety measures. Preferences for fast mobilization or after-hours service may add premiums.
Labor & Installation Time
Labor costs scale with crew size and time on site. Typical installations involve one operator and one helper for setup, plus a spotter if access is tight. Expect 1–3 hours per hole for standard conditions, with longer durations for multi-hole or high-precision cores. In regions with high labor rates, hourly costs may approach the upper end of the range.
Regional Price Differences
Prices vary by region, with urban centers generally higher than suburban or rural areas. In the Northeast, total per-hole costs may be 10–25% above national averages due to higher labor and permitting costs. The Midwest tends to align closely with national averages, while the South can be lower by roughly 5–15% in many markets. For multi-hole projects, regional differences compound with travel time and crew availability.
Additional & Hidden Costs
Hidden costs often appear as lead-time fees, extended dust-control requirements, or disposal surcharges. Some projects require additional vacuum systems or water suppression, which add rental or consumable fees. If a job requires core removal and reinstallation of fixtures, there may be added labor and transportation charges. Clarify whether core samples must be saved or tested, as that may incur an extra line item.
Real-World Pricing Examples
Concrete core drilling quotes vary by project specifics. Here are three scenario cards to illustrate typical budgets.
- Basic — One 4″ hole, minimal access challenges, standard drill depth (6″). Labor 1 hour, equipment, disposal. Total: $110-$180; per-hole: $110-$180.
- Mid-Range — Three holes, 4″ diameter, 8″ depth, moderate access, standard dust containment. Labor 3–4 hours, equipment, permits where required. Total: $480-$760; per-hole $160-$250.
- Premium — Four 6″ holes, 12″ depth, tight access, after-hours work, specialty containment. Labor 6–8 hours, premium equipment, higher disposal costs. Total: $1,100-$1,900; per-hole $275-$475.
Assumptions: region, specs, labor hours.
Pricing FAQ
Q: Do core drills charge by hole or by project? A: Most providers quote per hole, with a project total for multiple holes that includes shared mobilization.
Q: When should I expect permit costs? A: Permits are often unnecessary for residential work but may apply to commercial or city-authorized jobs.
Q: Are core drill services priced per diameter? A: Yes, larger diameters increase both equipment time and bit wear, raising per-hole costs.
Q: Can you save money by reducing dust-control measures? A: Reducing containment can lower upfront costs but may incur cleanup or compliance risks; discuss options with the contractor.
