Hire a general contractor when a project crosses multiple trades, needs permits and inspections, changes structure or layout, or runs longer than a couple of weeks. The GC coordinates the subs, sequences the work, pulls permits, and is accountable for the finished result, so you're not managing a half-dozen tradespeople yourself. For single-trade jobs, you usually don't need one.
We build websites and SEO for general contractors, and we run our own home-service companies. This is the honest homeowner version of when a GC earns their markup and when hiring trades directly or doing it yourself is smarter.
A kitchen or addition needs framing, plumbing, electrical, drywall, and finishes in the right order. A GC sequences them so the plumber isn't waiting on the framer and you're not the one calling everyone.
Structural work, additions, and major systems need permits and pass-or-fail inspections. A GC handles the paperwork and makes sure the work meets code, which protects your home's value and a future sale.
Moving walls, changing the layout, or anything load-bearing carries real risk. A licensed GC carries insurance and stands behind the result if something goes wrong.
A multi-week job is a part-time management job. If you can't be on site daily to make decisions and keep trades moving, the GC's coordination is worth the markup.
A general contractor typically adds 10 to 20 percent on top of the project cost, or builds it into a fixed bid. On a $40,000 renovation that's roughly $4,000 to $8,000. What that buys:
Plenty of projects don't justify the markup. Hire the specialist directly, or DIY, when:
The honest rule: pay for a GC when the project's complexity, permits, or timeline would otherwise become your second job. For anything simpler, the specialist alone is faster and cheaper.
This is the kind of page we build for general contractors β a genuinely useful guide that ranks in search and turns homeowners planning a project into estimate requests. We hand-build the site, add 24/7 AI lead capture, and publish researched pages every month. Plans run $249/mo for the site plus lead capture, $597/mo to add the monthly SEO engine, and from $1,750/mo for the full CRM and reputation stack. Month-to-month, and you own everything.

We don't post stock testimonials. On a 15-minute call we screen-share the real dashboards behind our own businesses — live leads, rankings, and the exact page that produced each one. See the proof →

On smaller jobs, yes β you hire and schedule trades directly and save the markup, if you have the time, know the order of work, and can be on site to decide.
For single-trade work like painting, flooring, or a fixture swap, and for small no-permit jobs. Hire the specialist directly when only one trade is involved.
