Milling Wood Flooring Guide While wood floor milling and asphalt pavement milling serve different industries, the same principle applies: having the right milling equipment in-house transforms a business from a service buyer into a service provider with full control over quality, scheduling, and profit margins. In the asphalt industry, cold planers and milling machines represent investments of $200,000 to more than $300,000 per unit. At first glance, this makes subcontracting look like the prudent choice. Yet many paving contractors who have made the leap report that the investment pays for itself rapidly and transforms their entire operation.
This article examines the real-world experiences of four paving contractors who own and operate milling machines. Their stories reveal how ownership affects business control, productivity, safety, material recycling, and the bottom line. Whether you are considering your first milling machine or expanding an existing fleet, these case studies offer practical insights into making milling a profitable part of your construction business.
The Case for Milling Machine Ownership
Control Over Operations and Scheduling
Harold Green, president of Chamberlain Contractors in Laurel, Maryland, puts it simply: “I don’t believe in working with subcontractors. I want to control my own environment.” His company performs pavement repairs and rehabilitation specializing in commercial parking lots, with 70 employees running three paving crews and a concrete crew. The need for control is acute under tight deadlines. “Customers give you the lot at 7 a.m. and they want it back at 7 p.m.,” Green says. A subcontractor breakdown means a missed deadline and a lost client. “We can’t tell people we had a breakdown, we sent everyone home, and we will be there tomorrow.”
Tim Murphy of Lojac Enterprises in Lebanon, Tennessee, agrees. His company handles government work on interstates and highways and owns its own asphalt plants. “Where you have to start milling big roadways and paving right behind, you need to be in charge of both ends,” Murphy says. “If the other guy breaks down, you only partially know where he stands.” Owning the machine means he can take corrective action immediately rather than waiting for a subcontractor to diagnose and fix their equipment.
Return on Investment Over Time
Chamberlain Contractors meticulously tracks hours and revenue for each milling machine in its fleet. The results demonstrate the long-term financial case for ownership:
| Machine | Purchase Year | Purchase Price | Revenue Generated | Times Paid For |
|---|---|---|---|---|
| Wirtgen (1986) | 1986 | $133,000 | $1,990,602 | 15x |
| Ingersoll-Rand Procut 2000 | 1991 | $212,000 | $991,000 | 4.7x |
The 1986 Wirtgen has clocked 14,000 to 15,000 hours with only $15,000 to $20,000 in maintenance costs over two decades. Rick Royals of Royals Contracting in Raleigh, North Carolina, saw his company’s revenue jump from $1.6 million in 2003 to $3.6 million in 2004 after buying his first milling machine. “A $300,000 cost, in the scope of things, is not a significant amount of money if you can significantly increase the productivity of your operation,” Green adds.
Productivity Gains From In-House Milling
Speed of Completion
Traditional pavement repair involves saw-cutting, excavating, hauling debris, replacing base material, and paving. Milling collapses these multiple steps into a single efficient operation. Royals Contracting experienced this firsthand. A shopping center with 500 tons of patchwork previously took five days with the best available crew. “It was very labor intensive and very expensive,” Royals recalls. After purchasing a Marini MP 1300, the same 500 tons of milling and patching took two days. Green reports similar results: “Instead of doing 400 or 500 yards, you can do 3,000 yards of asphalt repair a day. That means more money to the bottom line.”
Cost Per Ton Reductions
Royals quantified the savings from milling compared to traditional methods. The efficiencies come from three main areas:
- Labor reduction: Milling eliminates separate saw-cutting and excavation crews on the same job.
- Equipment consolidation: One milling machine replaces the combination of excavators, backhoes, and motor graders previously required.
- Material savings: Milled material can be recycled, reducing the need to purchase new aggregate base material.
“I can mill and patch somewhere in the vicinity of $25 to $30 per ton cheaper than the old way,” Royals says. At 500 tons per project, that translates to $12,500 to $15,000 in savings on a single job.
Fleet Flexibility With Multiple Machine Sizes
Contractors with multiple machines can tackle a wider range of projects without subcontracting. Lojac Enterprises operates three machines: an RX-60 with 86-inch cut for interstates, an RX-900 with interchangeable heads, and an RX-500 for metro streets. “The RX-500 is a good, flexible machine for a lot of smaller street paving. It is easier to get around and it isn’t too big,” Murphy says. This flexibility allows Lojac to bid on both interstate and municipal projects with the same fleet.
Safety, Recycling, and Versatility Benefits
Improved Jobsite Safety
Royals highlights a significant safety advantage on secondary roads. When widening older roads from 20 to 24 feet, the traditional method uses a motor grader and backhoe with workers exposed to passing traffic. “It is very dangerous to put people out there with cars whizzing by at 55 mph,” he says. Milling reduces the number of workers and pieces of equipment on the roadside. The State of North Carolina has begun specifying milling over traditional backhoe-and-grader methods specifically because of safety improvements. “You get so much more done and you eliminate a lot of equipment on the job that is a risk to the travelling public,” Royals notes.
Recycling Millings for Cost Savings
Every contractor emphasized the value of recycling milled asphalt. Dunn Co. in Decatur, Illinois, a full-service asphalt company operating since 1936, runs eight Wirtgen machines and recycles 100 percent of its millings through its own hot-mix plants. “Millings are worth a whole lot more running back in the plant than they are used as base rock,” says Jim Schwarz, vice president of marketing. “Every day that the cost of asphalt goes up, the load of roto millings becomes more valuable. We are able to maintain better margins.” Green of Chamberlain Contractors agrees even though his company does not own a plant: “You are paid to take it up and haul it away. You turn around and sell it as a byproduct. It is just good, solid business.”
Unconventional Applications
Dunn Co. has discovered that milling machines can replace excavators on projects that are not traditional milling work. “We will do some things with the mills that other contractors would do with an excavator,” Schwarz says. Golf cart path construction is one example. “Rather than go in with an excavator, we mill out for new paths. It does very little damage to the golf course and they are the exact width you want.” For patching, Schwarz notes that milling 4 inches deep and placing 4 inches of asphalt creates a stronger patch than the traditional saw-cut-and-excavate approach, all in a single operation.
Key Considerations Before Buying a Milling Machine
When Ownership Makes Sense
- Limited subcontractor access. Royals bought his first machine because the only local miller was too busy to schedule his work in a timely manner.
- Tight turnaround requirements. Green depends on returning parking lots the same day, making reliance on subcontractors untenable.
- Expansion opportunity. Dunn Co. generates more than half of its milling income from outside contractors. If there is unmet demand in your area, a machine can become a profit center.
- Recycling value. If you own an asphalt plant or can sell millings, the recycled material improves the financial equation significantly.
Calculating the True Cost of Ownership
| Cost Category | Estimated Range | Notes |
|---|---|---|
| Purchase price (4-ft machine) | $200,000 – $300,000+ | Varies by manufacturer and configuration |
| Annual maintenance | $750 – $1,500/year | Based on Chamberlain’s 20-year data |
| Transport equipment | Varies | Lowboy trailer for larger machines |
| Revenue potential | $25 – $50 per ton | Depends on local market rates |
General Conditions Overhead and Profit in Construction Understanding is essential when evaluating any major equipment purchase. A milling machine that is underutilized will never deliver the returns described in this article. Matching machine capacity to your annual workload is the critical factor.
Strategies for Maximizing Utilization
How Land Acquisition Sets Profit Potential in Home Building shows that upfront investment decisions have long-term consequences for profitability. The same principle applies to milling equipment.
- Start with one machine matching your most common project type. Royals began with a 4-foot 3-inch Marini MP 1300 and expanded from there.
- Build milling into standard procedures so every estimator and project manager considers milling before defaulting to traditional methods.
- Contract milling services to other local contractors during slow periods. Dunn Co. generates more than half of its milling revenue from outside sources.
- Invest in preventive maintenance to keep machines running during peak season. Chamberlain’s low maintenance costs over 20 years demonstrate the value of disciplined care.
Milling Wood Flooring Rough Lumber Guide covers milling in a different industry, but the business logic is the same. Whether milling lumber or asphalt, owning the equipment means controlling your production schedule, quality standards, and profit margins.
The Bottom Line
Milling machine ownership is not the right choice for every paving contractor. If you have reliable access to competitive subcontractors, few mill-and-fill projects, or insufficient capital, subcontracting remains a sensible option. However, for contractors facing limited subcontractor availability, tight project timelines, high annual milling volumes, or the ability to recycle millings, the case for ownership is strong. The four contractors profiled here found that their milling machines are not just tools but profit centers that pay for themselves many times over through improved efficiency, material recycling, and the ability to take on projects they could not handle otherwise. As Green puts it, “You are not selling a price, you are selling a service and a capability.” For contractors who want to offer that capability on their own terms, investing in a milling machine remains one of the most effective ways to build a more profitable paving business.
