Painting FAQs — Chicago Painting Questions Answered

While DIY window installation is possible, it’s not recommended unless you have experience. Improper installation can lead to air leaks, water damage, and energy loss. A licensed window contractor in Chicago ensures proper fitting, sealing, and insulation for long-term performance.

In most cases, a permit is not required for basic window replacement if the structure remains unchanged. However, if you’re making significant alterations, such as changing the window size or shape, you may need a Chicago building permit. Check with your contractor for guidance.
