Reviews

What Chicago homeowners say.

"They turned our attic into a master suite with a dormer that matches the original 1920s brick. The crew cleaned up daily and finished two days early."

Laura R.
Second-Story Addition

"123 Remodeling converted our unused garage into a legal rental studio. Permits were approved in six weeks and the first tenant moved in last month."

David M.
ADU Conversion

"Our 1970s kitchen was dark and cramped. They removed a load-bearing wall, added an island, and now we host holidays without bumping elbows."
