Casement Windows

Casement windows hinge on the side and open outward. They offer excellent airflow, unobstructed views, and a modern aesthetic. Casements are perfect for areas where you want maximum ventilation.

Sliding Windows

Sliding windows open horizontally along a track. They are low-maintenance, space-saving, and ideal for areas with limited exterior space.

Awning Windows

Awning windows are hinged at the top and open outward, creating a protective cover from rain while allowing airflow. They work well for basements or areas that need extra ventilation.

Specialty and Custom Windows

Bay, bow, or uniquely shaped windows add personality and architectural charm. Custom windows are excellent for creating focal points in new construction homes -learn more about planning for new construction projects.

Preparing for Window Installation

Checking the Rough Opening

Understanding Building Codes and Permits

Check local building codes and permit requirements before installing new construction windows. This ensures compliance and prevents costly fines. For new construction homes, it’s also important to know when property taxes start on your project.
