Even the highest-quality windows will underperform if they aren’t installed correctly. In fact, poor installation is one of the top causes of air leakage and water intrusion in homes.
Common Issues Caused by Bad Window Installs
Cold drafts in winter and overheating in summer
Mold growth and interior water damage
Swollen window sills and damaged drywall
Reduced energy efficiency and higher utility bills
What Proper Installation Looks Like
Air Sealing: Gaps around the frame are sealed with expanding foam and vapor-permeable tapes to prevent airflow.
Flashing: Proper sill flashing, head flashing, and pan detailing keep water from penetrating wall assemblies.
Level & Square Setting: Windows are aligned precisely to avoid stress and ensure smooth operation.
Integration with WRBs: Windows are tied into the building’s weather-resistant barrier to prevent moisture intrusion behind cladding.
