# How to find subcontractors for residential work

Finding trade partners

Start with the work you need covered. Use that scope to ask for referrals, screen comparable projects, and confirm who can take the job.

## Start with the work you need covered

You need a sub for a particular house, scope, and start window. Write down what you need. Then ask other trades, suppliers, and associations for names, and search for crews in your area. Screen each candidate for comparable work and capacity before asking for a price.

Shortlist subs who fit the work. Decide what to ask each one next. Keep discovery, [vetting](/guides/vet-a-subcontractor/), bidding, and award as separate decisions. Check even the names that come from people you trust.

## Move each candidate through separate decisions

Use this suggested sequence to keep an introduction from becoming an accidental award:

| Task | Decision to record | Where to continue |
| --- | --- | --- |
| Discovery | Candidate wants the offered scope and a follow-up | This guide |
| Work and crew fit | Examples, field lead, and capacity fit the package | [Find good subcontractors](/guides/find-good-subcontractors/) |
| Evidence validation | Required records match the entity and job; discrepancies are resolved | [Vet a subcontractor](/guides/vet-a-subcontractor/) |
| Award and release | Comparable bid, agreed terms, named approval, and ready site | [Hiring subcontractors](/guides/hiring-subcontractors/) |

Use [prequalification](/guides/subcontractor-prequalification/) to maintain bid-list eligibility between jobs. Repeat job-specific checks when the proposed scope, employer, or dates change.

## Start with the trade package

Before you call anyone, put the work on one page. Use the same brief for every introduction.

One residential builder, [Constructed Matter](https://www.constructedmatter.com/prequalification), asks prospective trade partners about trade, area, suitable project size, and pricing. It describes scope and scheduling discussions before matching approved partners by trade, area, and capacity. Use this builder's process to choose your own screening questions.

Put these details in your search brief:

| Field | What to write |
| --- | --- |
| Work | Trade, project type, and work package |
| Place | City or ZIP and relevant travel constraints |
| Documents | Plans, revision date, specifications, and missing information |
| Boundaries | Included work, exclusions, and material responsibility |
| Timing | Desired start window, dependencies, and completion needs |
| Site | Access, occupancy, storage, and readiness questions |
| Bid | Response deadline and the person answering questions |

For example, describe a framing package for a residential addition with the current plan revision. Ask about tie-in experience and the proposed start window. Say what the crew must price and supervise. “Carpenter needed” leaves that unclear.

If the scope is incomplete, say what remains open. Ask whether the sub wants an initial call or needs more information to give a firm price. Do not ask them to price an undecided design choice as a fixed quantity.

## Ask people who know the work

Begin with subs you have used on comparable projects. Ask who they would contact for this package and why. Then ask the supplier or pro desk that serves the relevant trade.

For a package with an unusual assembly, use the [specialty-trade search checklist](/guides/specialty-trades-for-remodelers/) to prepare a more specific referral request.

Keep the question narrow: “Who handles occupied-home flooring work in this area, including the preparation in this scope?” Ask what the referrer has seen firsthand. Separate a recent shared project from a business card left at the counter.

California's [CSLB lists customers, material suppliers, and subcontractors as reference sources](https://web.cslb.ca.gov/consumers/hire_a_contractor/Finding_The_Right_Contractor.aspx). Use that California consumer guidance to identify introductions. It does not approve a referred crew for your job.

Record who gave you the name, which project they know, and whether you can mention them. Ask for an introduction when appropriate. Do not publish private phone numbers or assume a supplier wants to endorse every company on your list.

If you are starting as a new GC, tell the referrer what you can provide. Explain how far along the scope is, who makes decisions, and how you will answer questions. The sub needs to decide whether to work with you, too.

## Search by trade, location, and project type

Use association contacts, company websites, and trade-and-location searches when your existing network cannot cover the work. [NAHB describes networking](https://www.nahb.org/nahb-community/member-benefits/networking) through national, state, and local association activities. Check the particular organizer's audience and access rules before spending time or money.

Search for the trade and the actual project area. Review the company's description, service area, and work examples. Ask whether the company does your kind of residential work. A trade name alone does not answer that.

Check each company page for these details:

- Does the company show work comparable to this package?
- Does its stated service area cover the site?
- Does the contact represent the business doing the work?
- Does the company do the work you need or a related specialty?
- Does the company say where to send bid inquiries?

Use the company's chosen contact channel. Request permission before visiting an active site. A worksite is not an invitation to interrupt a crew or inspect another client's house.

## Ask what the sub can do and when

Tell the candidate what you need before asking when they can start. Ask whether they want to consider the work. If they decline, record the reason and move on.

For a candidate who is interested, ask who would supervise and which comparable project they can discuss. Then ask what else is booked, when the crew can start, and what must be ready. Record conditions such as “after our current job closes” instead of calling it a firm Monday start.

Ask:

1. Which part of this scope do you perform, and what do you exclude?
2. Who would estimate, supervise, and handle punch work?
3. What information is missing before you can quote?
4. What existing commitments affect this start window?
5. Which similar project can we discuss with a reference you have cleared us to contact?
6. What site conditions must be ready before your crew arrives?

Use these questions for the conversation. Do not turn the answers into a numerical score. If an answer changes, update the record and ask how it affects the work. Finish the checks even when the first call goes well.

## Review the work behind the photos

Use one comparable example to decide whether a fuller conversation is worthwhile. Ask which part the company performed and whether it wants this package.

Move the interested candidate to [work and crew fit](/guides/find-good-subcontractors/) for the detailed review of workmanship, supervision, and capacity. Keep the discovery record to the introduction, offered scope, response, and next contact.

## Verify before you award

An introduction is the start of qualification. North Carolina's [GC board search](https://portal.nclbgc.org/Public/Search) identifies license records; the [board FAQ](https://www.nclbgc.org/faq-contractors/) explains that a license belongs to the named entity. A similar company name is not enough.

Use [evidence validation](/guides/vet-a-subcontractor/) before treating credentials as checked. Use [hiring subcontractors](/guides/hiring-subcontractors/) when you are ready to compare proposals and award work. Keep tax and financial attachments out of discovery notes. The [FTC recommends limiting sensitive information and access to business needs](https://www.ftc.gov/business-guidance/resources/protecting-personal-information-guide-business).

## Send a useful first message

Use this template after confirming that the work appears to fit. Replace the brackets with verified project information:

> We build [project type] in [area] and need [specific package] for a site in [town or ZIP]. Our proposed start is [window], subject to [readiness condition]. The scope is [labor only or supply and install]. Do you take this work, and who should receive the drawings for review?

Ask for permission to send project documents through an agreed channel. Agree who does what next. If the candidate declines, record the scope or timing reason without treating it as a quality judgment.

## Hand off the shortlist for bids

Hand the shortlist to the person managing bids. Record the scope version each interested candidate received and the next response date.

Continue with [comparing bids and awarding the package](/guides/hiring-subcontractors/). Discovery ends with permission to continue, not a booked crew or an approved subcontract.

## Keep backup contacts current

Keep names you have permission to contact again. Record the referring person, offered work, service area, last contact, and interest in the next package.

Build the [backup bench](/guides/backup-subcontractor/) around exposed packages. Use the [candidate-request checklist](/guides/subcontractors-needed/) to explain an unfilled scope.

Ask about interest again when a job opens. An old availability answer does not reserve a crew. Send a changed scope to [fit review](/guides/find-good-subcontractors/) and changed credentials to [vetting](/guides/vet-a-subcontractor/).
