Find contractors

Find construction companies by trade, revenue, and project

Construction is a phone industry. The owner is on a site, the office answers a landline, and an email to a shared inbox gets read on Sunday night if at all.

Trade is the filter that matters and the one nobody standardizes. A general contractor, a mechanical sub, and a civil outfit share a category code and buy entirely different things. Read the services page and the project gallery and the trade sorts itself out.

Sourcing runs off listings. Open Web Ninja returns the businesses, Serper catches the ones that rank without a claimed listing, and People Data Labs adds headcount and the group above a multi-entity contractor. Contacts start at Blitz API, and ClearoutPhone checks the number before anybody dials.

Example searches

Ask for it the way you'd say it

Every search below runs on the same hosted Tables, with the cost previewed before anything is spent.

  • Trade, not category code

    mechanical and plumbing contractors in colorado with 20 to 200 staff

    Trade is read from the services and project pages, so a firm whose listing says general contractor still sorts correctly.

  • Commercial work only

    contractors whose project gallery shows commercial and multifamily builds

    Project pages become a column, which separates a commercial builder from a residential remodeler far better than a revenue band does.

  • A number that connects

    for each contractor find the office line and a mobile for the owner, then validate both

    Validation runs before dialing, so a disconnected line is flagged in the row instead of discovered by a rep on a Tuesday.

Plays

Three motions you can run this week

Each one is a chain of Oxygen primitives — the same hosted objects your workspace already has, composed.

  • Trade-sorted list

    One list per trade, so the opener matches the work the crew actually does.

    1. Tables
    2. Tags
    3. Records
    1. 1Read services and project pages into a column, then tag the trade the evidence supports.
    2. 2Promote each tag as its own segment and keep the evidence cell attached to the row.

  • Phone-first cadence

    Reps dial numbers that ring, and the dead ones are removed before the list ships.

    1. Tables
    2. Sequences
    1. 1Run phone lookup and validation as columns, then drop rows with no working line.
    2. 2Route the survivors into a call step with email as the follow up, not the opener.

    You reach a builder in the window between an award and mobilization.

Who you can reach

Roles you can find at contractors and construction firms

Reachability is per channel: a role marked for mobile is one the phone waterfall usually resolves, not a guarantee for every record.

Filters you can search on

  • Trade read from services and projects
  • Licence class and state where published
  • Employee and crew size band
  • Commercial, residential, or civil work
  • Service radius and regions covered
  • Project types shown in the gallery
  • Fleet or equipment mentioned on the site
  • Years in business

Businesses, addresses, and phone numbers resolve well in this market. Work email is thinner: many contractors run on one shared office address, and the owner's real inbox is a personal one nobody will sell you. Plan a phone-led lane and treat email as the follow up.

Data sources

What the data actually comes from

Every value lands with its provider and cost recorded on the cell.

  • Op

    Open Web Ninja

    Contractor listings with address, trade category, phone, and hours.

  • Serper

    Search and map coverage for firms that rank locally but never claimed a listing.

  • People Data Labs

    Company records with employee bands and the group behind a multi-entity contractor.

  • Blitz API

    Head of the contact chain for owners, estimators, and operations managers.

  • ClearoutPhone

    Validates each number and reports line type, so reps stop dialing dead lines.

Run these on Oxygen's managed credits, or connect your own provider keys and pay the vendor directly — the same columns, the same runs, the same provenance either way. See every integration.

Limits

Where this stops

  • Revenue is not published for private contractors, so any size band here comes from employee count, fleet, and project scale. Treat it as ordering, not as a number you repeat back to the owner.

FAQ

Questions people ask first

How do you classify trade?
From the services page and the project gallery rather than a listing category. Contractors register under broad codes, and the work they show is a much better guide to what they will buy.
Why lead with the phone?
Because that is where the industry answers. Office lines are published, mobiles resolve for owners, and a validated number gets further than a message sitting in a shared inbox.
Can I find the estimator or project manager?
At mid-size firms, usually. Small contractors have one person doing all of it, and the row records the title it found so you can tell the two situations apart before writing.
Is licence data available?
Only where a contractor publishes it, which many do on their own site. State registers vary in what they expose, so treat the licence column as evidence rather than a verified lookup.
How do I keep out residential remodelers?
Filter on the project gallery, not on revenue. Commercial and multifamily work looks completely different in photographs and in the language used to describe it.
Can I push the list into my CRM?
Yes. Qualified rows are promoted onto company records with provenance attached, and the sync writes them to a connected CRM without losing where each field came from.
