I get this question more than you'd think. Usually it comes in the form of: "Why am I paying 21% to someone who doesn't swing a hammer?"
It's a fair question. On the surface, the general contractor fee looks like a markup on top of the actual work. You could hire the plumber, the electrician, the tile setter, and the painter yourself. They'd each give you their price, and you'd save that 21%.
Except you wouldn't. And here's why.
What We Actually Do All Day
Let me walk you through a random Tuesday on a $500,000 kitchen renovation that's in its eighth week of construction.
At 7:00 AM, our construction manager is on site confirming that the framing crew has what they need to start the header for the new window opening. The structural engineer specified a specific LVL beam size, and we need to verify the lumber delivery matches the spec before anything gets cut.
By 8:30, the plumber calls. He needs to know the exact rough-in dimensions for the pot filler above the range. That depends on the range hood duct routing, which the HVAC sub is supposed to finalize today. Our CM calls the HVAC sub to coordinate — turns out he was planning to run the duct a different route than what we'd discussed. We catch the conflict before either sub starts work.
At 10:00, the tile supplier emails to say the handmade tile the homeowner selected is backordered three weeks. We need to decide: wait and adjust the schedule, or present alternatives. We pull three comparable options, price them out, and call the client with a recommendation.
After lunch, we're reviewing the electrician's invoice from last week against our scope of work. He billed for six additional recessed lights that weren't in the original plan. We check the daily log — turns out the designer asked for them during a site visit. That's a legitimate change order, but it needs to be documented properly and approved by the client before we pay it.
At 3:00 PM, the drywall crew is finishing in the master bath. Our CM inspects every wall — checking for proper blocking behind towel bars and grab bar locations, verifying moisture-resistant board is installed in wet areas, confirming all electrical boxes are flush with the finished wall surface. He finds two boxes that are recessed too deep. The drywall crew fixes them before taping.
By 4:30, we're updating the project schedule, writing tomorrow's daily log, and sending the homeowner their weekly update with photos and a summary of the week's progress.
That's one day. On one project.
How We Work
SA&Co focuses entirely on project management, coordination, and quality control. We don't self-perform any trade work — no framing, no plumbing, no electrical, no painting. Instead, we coordinate a network of 15 to 20 specialized subcontractors, each one vetted, insured, and held to our quality standards.
This model exists because no single person — and no single company — is the best at every trade. The best framer isn't the best tile setter. The best electrician isn't the best painter. By working with specialists, we get the best work in every category rather than the most convenient.
Our job is to make all of those specialists work together as if they were one team. That means scheduling them in the right sequence, making sure each sub has what they need when they arrive, resolving conflicts between trades, inspecting work quality, managing the budget, and keeping the homeowner informed every step of the way.
What the Fee Actually Covers
That 21% covers more than most people realize:
Project management time. Someone has to be on your project every single day — coordinating, inspecting, problem-solving, communicating. On a four-month project, that's hundreds of hours of skilled management.
Overhead. Insurance, vehicles, office operations, technology, accounting, legal — the infrastructure required to run a construction company properly. General liability insurance alone for a company doing $2M in work is substantial.
Warranty reserves. We back our work for up to 20 years. That commitment has real costs — future inspections, potential repairs, record-keeping. Responsible companies set aside reserves for warranty obligations.
Coordination and logistics. Scheduling 15 subcontractors on a single project is like air traffic control. One delay cascades through the entire schedule if you're not managing it proactively.
Quality control. Every piece of work gets inspected before the next trade covers it up. That inspection catches problems early — when they cost $200 to fix instead of $20,000.
The Math on Doing It Yourself
Let's say you decide to be your own general contractor to save that 21%. Here's what actually happens.
The plumber and the electrician show up on the same day for the same wall. One of them has to leave and come back — and they'll charge you for the wasted trip. The tile setter arrives to start the shower, but nobody installed the shower pan membrane yet because you didn't know that was a separate trade. The cabinet delivery shows up three days early because nobody coordinated the schedule, and now you're storing $40,000 worth of cabinets in your garage hoping they don't get damaged.
Meanwhile, you're fielding calls from five different subcontractors who each need decisions, taking time off work to meet inspectors, trying to figure out if the drywall looks right, and wondering why nobody told you that the backsplash tile needs to be ordered eight weeks in advance.
The 21% you "saved" gets eaten up by scheduling inefficiencies, rework from poor coordination, and the value of your own time. Most homeowners who try to self-manage a major renovation end up spending more, not less — and the stress isn't worth it at any price.
How to Evaluate a General Contractor
Price matters, but it shouldn't be the only thing you evaluate. Here are better questions:
What does your preconstruction process look like? If the answer is "we'll give you a number next week," they're guessing.
Who are your subcontractors? A good GC has long-term relationships with quality trade partners. Ask how long they've worked together.
What's your warranty? And is it in writing? Specifics matter more than promises.
How do you communicate during construction? Weekly updates? Daily logs? Who's your point of contact? How quickly do you respond to questions?
Can I talk to a recent client? Not just a reference from five years ago — someone whose project finished in the last six months.
The right general contractor isn't just a middleman. They're the person who turns your investment into the home you imagined — on time, on budget, and built to last.
