Ask what the rep knows from direct experience
Ask the supply house for a sub worth calling. Ask how the rep knows the sub. It might come from working on a material package, resolving a delivery question, or communicating with the business at the counter.
Builders FirstSource’s services page describes sales representatives and specialist services, with availability varying by location. That describes one supplier’s work with trade buyers. It does not mean every rep observes completed installation or verifies a contractor’s workmanship.
Ask which part of the candidate’s work the rep has seen. A supplier may know how a firm communicates about orders while knowing little about its punch response. Record what the rep knows and what you still need to check.
Do not ask the rep to guarantee reliability. Ask for a relevant introduction and context. Then request comparable work and builder references from the firm itself.
Ask the branch or rep who knows the material
Begin with the branch, counter, or outside rep you use for the relevant material. If that contact handles another category, ask who understands the system you need. Describe the work. A trade name alone may not tell the rep what you need.
For windows, clarify whether you need product selection, new installation, replacement, or repair. For millwork, distinguish supply, fabrication, and site installation. For a roof package, state the system and whether the work is new construction or a remodel.
Use those distinctions to ask what the supplier offers. Ask the local business which roles it can discuss. Confirm whether it offers installed services itself or can only suggest an independent contact.
You can also ask a local building association. NAHB’s membership description includes suppliers, service providers, and product manufacturers among associates. Ask your local association about relevant connections without implying that a supplier or member is affiliated with Cercha. Use NAHB’s local association directory to find the association to contact.
Give the rep the scope, location, and job size
Bring the same search brief you use with a builder peer. State the scope, location, job size, proposed start, and material responsibility. Explain what makes this sub hard to find.
Use this suggested conversation:
We have [residential project type] in [area] and need [specific package]. The work is [labor only or supply and install], with [key existing condition or material]. Do you know a company that takes this size of job? What work or interaction makes it a name you would suggest?
If the rep offers a name, ask who to contact and whether an introduction is appropriate. Confirm that the contact details are intended for business inquiries. Avoid requesting a customer’s private address or personal number without permission.
Ask whether the firm usually takes your type of work. If the rep does not know, leave it as a question for the first call. Do not record a guess as an endorsement.
Record what the rep has seen firsthand
Keep a short note about the source, date, and basis of the introduction. Distinguish direct observation from something the rep heard. If the rep names a company but has not dealt with it, mark the entry as an unverified lead.

| What the rep describes | Follow-up for the candidate | What it does not tell you |
|---|---|---|
| Material-package interaction | Which products and scopes do you install? | Buying a product does not establish installation performance |
| Clear order communication | Who handles our estimating and field questions? | One supplier interaction does not cover every project stage |
| A project the rep visited | What was your role, and who can discuss it? | A visit may show only part of the work |
| A firm mentioned by a peer | Can we see comparable work and speak with a reference? | The recommendation is secondhand |
Ask the rep to stay within appropriate business information. Do not request credit balances, payment history from confidential accounts, or another builder’s terms. Complete your hiring checks without asking for another customer’s private records.
Avoid using the supplier’s logo or name as a public endorsement of the candidate. A private introduction does not give you permission to advertise the recommendation. Keep your own note factual.
Check the sub before awarding work
Contact the firm with your package, explain the referral, and ask whether it wants to review the scope. Confirm the contracting entity, service area, assigned lead, and likely crew commitment. Request comparable examples that match your work.
Use the reference interview and capacity review to test the referral against your actual package.
Ask for references from the jobs shown in those examples. Ask a builder what the company completed, how it handled handoffs, and whether it closed corrections. The FTC’s contractor guidance recommends trusted recommendations and critical review of reputation information. Check the referral before deciding to hire.
Review the written scope before price. Identify exclusions, material responsibility, required return visits, and readiness conditions. If the supplier also supplies the package, agree who decides what to do about substitutions or shortages.
Complete required license and insurance checks separately. Use the official NC GC license search for applicable general contractor credentials, matching the firm’s identity to the record. For North Carolina insurance, the COI statute says a certificate cannot add coverage beyond the policy. Ask your licensed agent to assess project requirements and relevant policy documents.
If the firm declines, keep the reason. A contractor that does not take small repairs may still fit a later complete installation. Record the work it takes. Do not mark down its quality because it declined a different scope.
Give the referred sub a clear next step
Give the candidate a clear next step and usable information. Send the current plans after it agrees to review them. State when you will decide and who handles questions.
When a job is awarded, use your normal agreement and start process. Involve the rep in material coordination when that is part of its role. Do not make the supplier responsible for a contractor’s performance because it supplied the introduction.
After the job, thank the rep for the connection and describe the result without sharing private job details. Note that the firm fit the package for future referrals. Keep that note separate from any public testimonial.
Tell suppliers which jobs your trade business takes
If you are the sub, give the supplier a clear description of work you want. Include service area, project types, materials or systems you handle, and the business contact for inquiries. Explain scopes you decline so a referral does not waste either party’s time.
Offer a short sheet describing your work, with examples you have permission to share. Identify your exact role in each project. Ask whether the supplier is comfortable passing your business details to a suitable inquirer.
Keep that information current when the contact, service area, or work focus changes. If you are booked, describe how you want future inquiries handled. Avoid asking the rep to promise a start date on your behalf.
Use the subcontractor search process to place this check within the wider candidate search.
Where Cercha fits
Cercha includes Building Supplier profiles with brands and direct Messages between members. Use a supplier connection to begin a scope-specific conversation, then inspect the trade member’s portfolio and builder endorsements. Confirm the introduction’s context and hiring evidence directly. Ask about the beta.
