Ask any busy general contractor what keeps them up at night and the answer is rarely price. It's the sub who doesn't show up. That's your opening if you're a subcontractor or supplier. To find general contractors worth selling to, read the permit records to see who is actually building, check their license, join the builder association's lists, and drive past the jobsites. Then offer to be the reliable one.
Ines runs a three-person finish carpentry crew: trim, interior doors, built-ins and cabinet installs. She's been working for two homeowners and one builder. She wants five general contractors who send her work every month. Here's her path.
Why GCs are a good channel
A homeowner hires you once. A general contractor hires subs on every job, ten or twenty jobs a year, and prefers to keep the same ones. Winning one contractor can mean steady work for years, with one relationship to maintain instead of fifteen. They also pay on a schedule, which beats chasing a homeowner for a final check.
The trade-off is that GCs are busy, skeptical and used to flaky subs. They'll test you with a small job first. They'll compare you on reliability, quality and communication more than price, though price matters. So your job is to show up in front of them with proof that you're dependable, and to make starting easy.
Permit records show who is active
Building permits are public, and most cities and counties let you search them. Each permit lists the property, the type of work, the value and the contractor of record. Pull the last 90 days of residential new-construction and remodel permits in your county, sort by contractor, and count. The names that appear five or ten times are active builders who will need subs. The ones that appear once are likely homeowners or one-off projects.
Ines finds 160 permits and 34 contractors in her county. Nine appear four or more times. Those nine are her first list. Add the permit values too, since a contractor pulling $400,000 remodels needs finish work more than one pulling $20,000 repairs. Build a list without buying one has more sources of this kind.
License lookups
Every state licenses general contractors in some form, and the lookup is public. Search the contractor's name or license number and you can confirm they're active, see the business name and address, and sometimes check for complaints or insurance. That tells you who is real. It also helps you avoid contractors with a pile of unpaid-sub complaints, which is a risk you want to know about before you give them your best crew for a month.
Use the license record to find the legal business name and an address, then the company's website or a quick call to find the owner or the project manager who hires subs. For larger firms that's often a project manager or a purchasing coordinator, not the owner. Lead data you can check before paying offers a quick way to test any contact info you find.
Builder association lists
Local home builders associations and similar groups publish member directories with company names, contacts and categories. Many have a "find a builder" page open to the public. They also host events, trade nights and awards dinners where builders show up in one room. Membership costs money, so ask what the member mix is before you join. If it's mostly other subs and suppliers, it won't help you sell to GCs.
Free alternatives: building supply houses and lumberyards. The counter staff know every active builder in town, and a short chat with a friendly counter person can produce three names in ten minutes. Bring a card and don't pitch the counter. Just introduce yourself and say what you do.
Jobsite signs and drives
Most job sites post a sign or a permit board with the contractor's name. Drive a loop through the new subdivisions and remodel neighborhoods once a week with a notebook. Write down the address, the contractor's name from the sign and the stage of the job. Framing now means finish work in six to ten weeks. That's a perfect time to say hello.
Never walk onto a site without permission, wear the right gear if you're invited, and don't interrupt a crew. Note the builder's name and write to them. A message like "I saw your sign at 14 Alder Lane, it looks like framing is wrapping up. I do finish carpentry and have openings in March" is both honest and well-timed.
Getting on a bid list
Many GCs keep a bid list of subs they invite for each job. Getting on it is the goal of your first contact, so ask for exactly that. Ines's first email:
Subject: Finish carpentry sub for your spring jobs
Hi Mike, I saw your crew pulled permits for the Alder Lane and Birch Street remodels. I'm a finish carpenter with a three-person crew: trim, doors, built-ins, cabinet installs. I carry general liability insurance and can send a certificate and photos of recent jobs. Could you add me to your bid list for the spring? Ines Okoye, Okoye Finish Carpentry, 66 Mill Road, Spokane. If it isn't a fit, reply "no" and I won't write again.
Offer the paperwork up front: insurance certificate, W-9, license number, and references. It removes a step for them and signals that you're professional. CAN-SPAM requires your physical address and an opt-out, and 20 to 50 emails a day is a good pace. Follow up once after a week by phone, at 7 a.m. or after 4 p.m., since GCs are on jobsites in between.
Rocketship's AI worker can run the list and the emails on its own. Describe the buyer in plain English ("residential general contractors and remodelers in Spokane County"), and it finds them by name with verified contact details, emails them from your own Gmail, follows up, and books the call.
Keep the relationship warm
The first job decides everything. Show up when you said, finish when you said, clean up, and send a short summary with photos. Invoice the same day. Then check in every few weeks, even when there's no job: "Finished the Alder Lane trim last month, I have two weeks open in April." Send a short thank-you after a good job, and if you spot a scheduling snag (say, trim ordered before the paint is done), mention it early. Helping a contractor avoid a mistake earns more loyalty than a discount.
The home services page shows how Rocketship supports trades like yours on the customer side. Treat the contractor list like a pipeline of its own, because it is one.
