Honest partners, hard hats.

Founded in 2004 in Chicago's West Loop by two former union ironworkers and a civil engineer. We still price jobs the way we ran them: line by line.

We are not the biggest builder in Illinois. We intend to be the one you call back.

Summit Builders began with a single warehouse in Elk Grove Village. Twenty-two years later, we have delivered more than 300 projects for owners from Rockford to Joliet, and most of our work comes from people who have built with us before.

We self-perform concrete and site work, which means we control the two trades that most often decide schedule. Everything else is bid openly to a qualified bench of Illinois subcontractors, and we share the leveling sheet with you.

  1. 01

    One superintendent, start to finish

    The person who walks the footing is the person who signs the punch list. No hand-offs mid-job.

  2. 02

    The schedule is public

    A three-week look-ahead goes to the owner every Friday, whether the news is good or not.

  3. 03

    Safety stops the job

    Any worker can stop work. Our EMR of 0.71 is the result of that rule, not a poster.

  4. 04

    Local first

    We hire, buy and sub in Illinois wherever we can. Over 80 percent of our trade partners are within 60 miles of the site.
