What Does a General Contractor Actually Do?

Most homeowners have never watched a general contractor work, because most of the work happens somewhere they are not. The common assumption is that a contractor marks up the subcontractors and takes a cut. Here is what the job actually involves, including the part that surprises people and the part that is genuinely hard.

Infographic titled What Does a General Contractor Actually Do. Covers the assumption that contractors just mark up subs, assembling the project, carrying the risk, why it is mostly an office job, what a contractor does not control, what happens when a subcontractor runs late, and the hardest part of the job.

The Assumption, and Why It Looks That Way

Plenty of people believe a general contractor marks up the subs, skims off the top, and does not do a great deal else.

I understand why it looks that way. From outside, the trades are the ones doing visible work. They arrive, something changes, they leave. The coordination that put them there in that order on that day is invisible.

What you do not see is what happens without it. Strip out the general contractor and you have fifteen trades who have no idea when to show up, what order they go in, or what condition the space needs to be in before they can start.

Assembling the Project

Half the job happens before anyone picks up a tool.

That half is the scope, the pricing, the timeline, the permits, and the contract that puts all of it in writing. Hence the name contractor. The contract is the actual product of that phase, and everything downstream depends on how carefully it was built.

A vague scope is where remodels come apart. If the paperwork does not say who supplies the tile, or what happens when a wall opens and something unexpected is behind it, those turn into arguments later rather than decisions now. This is a large part of what to look for in a general contractor before you hire one, and it is worth more attention than most homeowners give it.

Running It, and Carrying the Risk

Once the project is assembled, the job shifts to running it. Keeping it on track, keeping it smooth, reducing risk where possible, and carrying whatever risk is left.

That last part deserves a moment. If something goes wrong, it is mine. It does not become the homeowner’s problem to solve, and that transfer is a real part of what the fee buys.

I am the professional middleman between you and your project. I vet the subcontractors. I inspect the work between phases and sometimes during them. Some of it is design work, because decisions surface mid-project that somebody has to answer, and that somebody usually needs to know the cost and the schedule impact before they can answer well. The full remodeling process from start to finish lays out where each of those decision points falls.

It Is Mostly an Office Job

This is the part that surprises people most.

I am on site nearly every day, usually somewhere between one and three hours. Sometimes longer depending on how busy we are, and that might mean one larger project or two or three running at the same time.

Plenty of days still run ten hours or more. Most of those hours go on scheduling, ordering, chasing materials, or sitting on the phone.

So you might not see my truck outside all day and wonder where I am. You would not want to watch most of that work. And if you did want to watch it, you would have to leave your own job to do it, which is the reason you hired somebody in the first place.

What a General Contractor Does Not Control

Here is something most people do not know. I do not manage my subcontractors’ schedules.

I cannot tell a sub what time to be there in the morning. What I can tell him is which day or which week we will be ready for his scope, and then it is on him to fit that into his own calendar.

The same limit applies to method. I can tell a subcontractor how I want the finished work to look and trust that he knows how to get there. I cannot stand behind him directing how he does it. That distinction is what makes a subcontractor a subcontractor rather than an employee, and it is exactly why the vetting on the front end carries so much weight. By the time somebody is on site, the quality decision has already been made.

What Happens When a Sub Runs Late

A subcontractor calls a week out and says he will be a day or two behind. Two things immediately become my job.

The first is telling you, as honestly and as early as I can, so your expectations move with the schedule rather than against it. Late news is worse than late work.

The second is absorbing as much of the hit as I can. That means getting on the phone with the other trades, working out whether the new date still holds together, and looking at whether there is another scope we can pull forward into the gap so the week is not wasted.

Most of what we do is minimizing damage from things we do not directly control. It is unglamorous, and it is a large share of the job.

When Something Is Not Done Right

Everybody has a bad day. When work is not right, it is on that subcontractor to fix it, and it is on me to bring it to his attention.

I have never had anything drastic go wrong. It is usually fit or finish needing touching up rather than anything structural.

There have been a couple of occasions where I brought in a different subcontractor at my own cost to make something right. I do not enjoy those days. They are part of the deal, and knowing that in advance is part of why the number on a bid is what it is. If you are weighing quotes, that is worth remembering when you compare bids from different contractors.

The Hardest Part Is Being the Bad Guy

If materials are delayed, that is the contractor’s fault. If a sub runs late, the contractor’s fault. If an inspection fails, the contractor’s fault. If there is a quality problem, including one I found and raised myself, still the contractor’s fault.

Whatever happens, it lands on the contractor. And to a point, rightly so. That is the job, and anyone who takes it on knowing otherwise is going to have a bad time.

One thing worth saying plainly though. If these things are reaching you at all, that is the contractor doing his job. Silence usually means somebody is hoping you do not notice until it is too late to matter. Either way it is still on me to fix it.

What You Are Actually Hiring

So, what does a general contractor actually do?

We assemble the project. We carry the risk. We stand between you and twenty moving parts, a building department, and a schedule that comes apart the moment anybody gets out of order.

You hire one person so that you are not managing fifteen.

Common Questions

Do general contractors just mark up subcontractors?

That is the common assumption and it misses where the work sits. The markup covers assembling the project before anyone starts, which means the scope, the pricing, the timeline, the permits and the contract, and then running it once it is underway. It also covers risk. If something goes wrong on the job it becomes the contractor's problem to solve rather than the homeowner's. Remove the contractor and you have fifteen trades with no idea when to show up or in what order.

Can a general contractor control when subcontractors show up?

Not to the hour, no. A contractor can tell a subcontractor which day or which week the project will be ready for his scope, and the sub fits that into his own schedule. The same limit applies to method. A contractor specifies how the finished work should look and relies on the trade to know how to get there, which is what separates a subcontractor from an employee. That is why vetting matters so much. By the time someone is on site, the quality decision has already been made.

What happens when a subcontractor runs late?

Two things become the contractor's job. Telling the homeowner honestly and early so expectations move with the schedule, and absorbing as much of the delay as possible. That means calling the other trades to see whether the revised date still works, and finding out whether another scope can be pulled forward into the gap. A great deal of general contracting is reducing the damage from things nobody directly controls.

Who pays when a subcontractor's work has to be redone?

The subcontractor is responsible for correcting his own work, and the contractor's job is to catch it and raise it. Most of what needs attention is fit or finish rather than anything structural. Occasionally a contractor will bring in a different trade at his own cost to make something right, which is one of the costs built into a real bid and one of the reasons the cheapest number is not always the cheapest outcome.
