Before you hire Interstate Welding & Mechanical Co INC

  1. Confirm the record on the official site

    Our copy is from the state's file dated November 9, 2026. The official record is live and also lists complaints and discipline, which our data doesn't include.

    Search MEC.0001123 on elicense.ct.gov

  2. Make sure the name on the contract matches

    The contract, the permit and the license should all name Interstate Welding & Mechanical Co INC. A different company name on the paperwork usually means someone else is working under this license.

  3. Check the license covers your job

    This is a mechanical contractor license. If your job is a different trade, the contractor needs that license too, or a licensed sub for that part.

Is this your license, or is something wrong?

This status comes from Connecticut's state credential data from the Department of Consumer Protection (home improvement, new home construction, major and trade contractors), file dated November 9, 2026, and it may have changed since. The official record is the one that counts. If it's wrong, the state has to fix it. If our page is the problem, or you want this record off our site, email us or see our corrections page.
