General Contractor

When you’re dining out, your job is simple: enjoy the meal. But it pays to know who's cooking when you’re building your dream home. A construction site, like a professional kitchen, relies on a variety of specialists. Understanding the roles of general contractors (GCs) and subcontractors – and how they work together – can ensure your project stays on track.

At BuildLabs, we break down these roles, the key differences, and how to choose the right professionals to bring your vision to life.

General Contractor vs. Subcontractor

Continuing the kitchen analogy, hire general contractor (GC) is the head chef. They’re hired by you, the client or developer, to oversee the entire project. From managing timelines and hiring trades to sourcing materials and ensuring everything is up to code, the GC ensures that the whole operation runs smoothly.

Subcontractors are like the station chefs who specialize in only one aspect of the process. Subcontractors, such as framers, electricians, plumbers, or roofers, execute their tasks under the GC’s coordination. Working under the general contractor’s direction, these skilled professionals transform raw materials into a cohesive, finished space, tailored to your unique vision.

What does a general contractor actually do? 

For clients, having a general contractor means having one point of contact instead of juggling dozens. The GC is responsible for overseeing the entire construction process, from the initial plans to the final inspection. They plan, schedule, problem solve, and communicate to ensure everything happens in the right order, on time and up to code, and within budget.

Here’s a closer look at what that includes:

Before Construction Starts:

  • Budgeting: Estimating labor, materials, and permit costs.
  • Hiring: Securing subcontractors and specialty trades.
  • Planning: Collaborating with architects and engineers, setting timelines, and reviewing plans and expectations with clients.
  • Permits & Paperwork: Handling all necessary approvals and ensuring compliance.

During Construction:

  • Scheduling: Coordinating who’s on-site and when.
  • Managing: Problem-solving and ensuring daily operations stay on track.
  • Quality Control: Ensuring all work meets the project’s standards.
  • Compliance: Making sure all safety protocols and building codes are followed.
  • Budget Oversight: Keeping expenses within the agreed scope.
  • Updates: Keeping clients informed and making adjustments as needed. 

After Construction:

  • Final Walkthrough: Ensuring everything is finished to satisfaction.
  • Punch List: Completing any last-minute tasks.
  • Closeout: Delivering all necessary documentation, manuals, and warranties

What does a subcontractor do?

Subcontractors bring specialized skills to the build. A licensed electrician wires the home. A tile contractor lays out the flooring. A mechanical subcontractor installs HVAC. Each subcontractor typically works under the direction of the general contractor, arriving on-site when their piece of the puzzle is ready. Their role is narrowly focused but essential – quality craftsmanship at each stage depends on their expertise. Many subcontractors run their own businesses and may work on several projects simultaneously.

Some of the most common subcontractor roles include:

  • Framing: Building the home’s structural skeleton.
  • Plumbing: Installing water, waste lines, and fixtures.
  • Electrical: Wiring the home for power and lighting.
  • HVAC: Installing heating, cooling, and ventilation systems.
  • Masonry: Laying brick, stone, or concrete.
  • Roofing: Ensuring the structure is protected from the elements.
  • Drywall & Insulation: Closing walls and regulating temperatures.
  • Tiling & Flooring: Installing finished surfaces.
  • Painting & Finishing: Adding the final touches to interior spaces.
  • Appliance Installation: Getting your kitchen and laundry functioning.

General Contractor vs. Subcontractor: Key Differences

Here’s a quick look at how general contractors and subcontractors differ in ways outside their job descriptions – and how that distinction impacts your build.

Work Relationship

The general contractor has a direct contract with you, the client, and hires subcontractors as needed. Subcontractors, by contrast, are contracted by the GC and don’t directly work with the client. The GC is responsible for managing the work of all subcontractors on the job site.

Nature of Work

General contractors manage the big picture – coordination, communication, compliance, and completion – while subcontractors handle the hands-on work. On larger jobs, subcontractors may even bring in their crews, sub-subcontractors. Simply put: the GC delegates, the subcontractor delivers.

Skills Requirement

GCs need broad construction knowledge, business acumen, and strong project management skills. They're planners and problem-solvers. Subcontractors are masters of a specific trade, deeply experienced and typically licensed in their area of expertise, whether that’s finish carpentry, masonry, or electrical systems.

Cost 

How much does it cost to hire a General Contractor in the Hamptons? Hiring a general contractor is typically more expensive up front, as you’re paying for full-service management. Subcontractors may offer lower individual labor costs, but working with them directly requires you to act as your own GC – which can lead to unexpected delays, missed inspections, or higher long-term costs if coordination fails.

How to Make the Right Choice for Your Project

Not every project needs a full crew, but scope, budget, timeline, and permitting requirements all factor in. Having a skilled and experienced general contractor on board, like BuildLabs, offers the structure and oversight to keep your project running smoothly – on time, on budget, and up to code.

Scope and Complexity

For smaller projects like replacing cabinets or retiling a bathroom, a subcontractor or two may suffice. However, for large-scale renovations or new builds, a general contractor provides structure, continuity, and expertise that’s hard to match.

Budget Considerations

Going directly to subcontractors might appear more affordable, but without managing timelines, permits, and inspections, mistakes can lead to costly delays. A GC helps you avoid these risks by handling these tasks professionally.

Time and Expertise

General contractors bring experience in coordinating trades, adapting plans, and solving problems. If you’re balancing other responsibilities, letting a GC handle day-to-day coordination can save you time and hassle.

Legal and Regulatory Requirements

Certain projects require a licensed general contractor, especially for large-scale builds or if the work exceeds a certain value. Licensed GCs handle permits and ensure compliance with local building codes. If you’re unsure, consulting a GC early in the process can help you avoid costly mistakes down the road.

Conclusion: The Right Professionals Make All the Difference

Just like in a well-run kitchen, it’s the combination of specialized talent and seamless coordination that leads to success. While subcontractors may be the experts in their trades, the general contractor – the head chef – brings everything together to create the finished product. Whether you’re managing your own project or bringing in a GC to guide the way, understanding their roles is key to building smarter.
