A dynamic, locally-owned excavation and concrete company — built on honest work and visible results.
Blair Excavation Inc. was established in 2023 under the leadership of Liam Herrera, the company's president. From day one, the mission has been straightforward: treat every excavation and concrete project like it's going on our own property.
That mindset shapes everything we do. We pull the right permits. We dig to the right depths. We use the right materials. And we don't leave a site until it looks like we were never there — except for the work that's now holding your property together.
Today, Blair Excavation serves residential and commercial clients across the greater Chicago area, with a specialty in sewer and water line installation and repair alongside a full range of excavation and concrete services.
Three words that aren't just for the brochure — they show up in how we plan jobs, protect our crews, and hand over finished work.
Utility locates, proper shoring, and trained crews. Nobody gets hurt, nothing gets hit.
Right-sized equipment and experienced operators mean jobs move — without cutting corners.
One point of contact, one quote, one crew. You always know who to call.
We restore the site. No ruts, no mess, no surprises when we pull off the property.
We work with homeowners upgrading their property, general contractors and custom builders managing new construction, and commercial clients with specific concrete and sitework needs. The team scales to the job — a residential sewer replacement and a multi-unit commercial foundation both get the same standard of work, just at different sizes.
Our service area covers Lakewood, Crystal Lake, Woodstock, McHenry, Algonquin, Huntley, Cary, Elgin, Barrington, and the surrounding communities within a 30-mile radius. If you're in the greater Chicago area, we can probably get there.
