About Us | MB Home Additions & Room Additions

Our Story

Chicago's Contractor Since 1995

MB Home Additions & Room Additions was founded in Chicago in 1995 with a straightforward mission: deliver the kind of craftsmanship and straight talk that homeowners in this city deserve. Over three decades, we've built our reputation one project at a time, serving families across Chicago's neighborhoods with the same care we'd give our own homes.

As a seasoned general contractor, we specialize in home additions, kitchen remodeling, bathroom remodeling, and full home remodeling. Every project starts with listening carefully to what a client actually wants, then applying expert attention to detail and skilled in-house craftsmanship to turn that vision into reality. We hold a 5-star rating across 20 Google reviews, and we intend to keep earning it on every job.

We are fully licensed and insured in the State of Illinois, and every project we take on is permitted through the City of Chicago. Our clients never have to chase paperwork or worry about code compliance. We handle it all.

Established 1995

"I started this company because I believed Chicago homeowners deserved a contractor who showed up on time, said what they meant, and built things that lasted. Thirty years later, that's still the only way we know how to work."

The People Behind the Work

Our Team

Every person on our crew is a full-time MB Home Additions employee, not a day-labor subcontractor. These are the craftsmen who show up at your home.

Marco Barrientos

Founder & Principal Contractor

Marco has led every major addition and remodeling project since founding the company in 1995. He holds an Illinois General Contractor license and reviews every project plan before a single tool touches your home.

Rosa Velasquez

Project Manager

Rosa coordinates scheduling, city permits, and client communication for every active project. She keeps jobs moving and homeowners informed at every stage of the build.

Daniel Kowalski

Lead Carpenter

With 18 years of Chicago residential framing and finish carpentry behind him, Daniel leads our build crews and ensures that structural and aesthetic quality meet our standards on every job.

What We Stand For

Our Values

Three principles that have guided MB Home Additions since 1995 and will still guide us in 2026.

Craftsmanship First

We measure twice and cut once, every time. The quality of our finish work on a modest bathroom remodel gets the same attention as a full home addition because we believe every client deserves our best.

Total Accountability

When we give you a price and a timeline, we stand behind both. No subcontractor finger-pointing, no change-order surprises. Your project, our responsibility from start to final walkthrough.

Transparent Process

We explain every step in plain language, share permit timelines honestly, and make sure you understand the build plan before any work begins. No surprises, no jargon, no runaround.
