There are a lot of mistakes in work. he doesn't want to fix it.
November 2025
We hired Kozak Renovation (owner – Yuriy) to renovate the main floor of our house, including the kitchen, bathroom, and ceiling. At first, everything seemed fine, but recently we discovered something shocking: both the bathroom and kitchen exhaust fans were not vented outside at all — they were simply dumped into the attic.
As a result, mold started to grow inside our roof structure, and our children, who suffer from allergies, began having serious allergic reactions. When we called a professional mold inspection service, they confirmed that the ventilation was installed incorrectly and did not meet Ontario Building Code requirements.
Yurii is very honest and straightforward. Had my basement finished and bathroom renovation done. Great value and quality, everything finished on time, easy and pleasant to work with them.Services: Paint indoors
