Local Factors
When planning your window replacement in Knollwood, consider these local factors:
- Permits: Lake County requires permits for window replacement projects, especially if you’re altering the window’s size or location. Check with the Lake County building department for specific requirements and fees.
- Installation Labor Rates: Labor costs in the Chicago metropolitan area, including Knollwood, are relatively high due to strong union representation. Factor in approximately $400 – $800 per window for professional installation.
Weather Impact
Knollwood’s weather presents unique challenges for windows:
- Freezing, Windy Winters: Chicago’s reputation as “The Windy City” means your windows need a high Design Pressure (DP) rating to withstand strong gusts. Invest in triple-pane glass with Argon or Krypton gas fills for superior insulation against sub-zero temperatures.
- Humid Summers: Look for windows with low solar heat gain coefficient (SHGC) ratings to minimize heat transfer and keep your home cool during the summer months.
- Lake-Effect Snow: The proximity to Lake Michigan can lead to heavy snowfall. Ensure your windows are properly sealed to prevent drafts and water damage. Warm edge spacers will greatly reduce the chance of condensation.
- Architectural Style: Many homes in Knollwood are historic brick bungalows or similar styles. Select window frames that complement the architectural style while offering modern energy efficiency.
