What Clients Say

Homeowners Trust Our Work

"We had Chicago Home Additions build a rear room addition on our bungalow in Jefferson Park. From the first meeting they were straight with us on price, timeline, and what to expect. The crew was on site every day they said they would be. The addition matched our existing brick perfectly and we passed inspection first try. We could not be happier with how it turned out."

Sandra M.
Room Addition, Jefferson Park

"I got three quotes for a detached garage addition in Norwood Park and Chicago Home Additions came in the most affordable by a significant margin. I was skeptical at first, but the quality of the build was excellent. They handled the city permit, poured a solid slab, and finished the structure ahead of schedule. I use it as a workshop now and it has been solid through two winters."
