When we ran our analysis, JJ Stucco & Plastering System Inc. had earned a Chooz Score of 82.7%. It operates as an owner-led stucco and plastering company based in Lake in the Hills, registered as a business entity with the Illinois Secretary of State, and it has served homeowners across the northwest Chicago suburbs for more than seven years. The company is led by owner Jan Konicek, who works the jobs with a small in-house crew. Across its review profiles, the company held over 50 Google reviews with a 5.0-star rating. A five-star average that holds across every one of those reviews is unusual at this volume, since most companies pick up at least a few lower ratings along the way. Across the reviews we analyzed, the work centers on stucco installation, repair, and restoration, along with EIFS exterior systems and exterior painting, and every review carried a five-star rating. Reviewers repeatedly describe the crew matching texture and color so that stucco and EIFS repairs blend into the original wall, the kind of specialized detail that sets stucco restoration apart from general exterior work. Reviews consistently reference Jan Konicek and his own employees doing the work rather than subcontractors, and the owner responds to most of the reviews we read with replies that name the customer and the specific repair. Several reviewers describe work on century-old homes, and we found at least two documenting repeat projects across multiple years. None of the reviews we analyzed fell below five stars, so there was no written criticism to weigh. "This is the second time we've worked with Jan and his team! We had worked with Jan and JJ Stucco 7+ years ago to re-stucco a large chimney where the finish had started to crack and peel. When additional stucco repairs were required on different parts of our house, Jan was the only person I called." - Nisha Y., Google Review
