Waterproofing is not just about preventing leaks; it’s about protecting your home from long-term moisture-related damage. Here’s why it should be a priority:
Prevents Costly Repairs: Water damage repairs can cost anywhere from $2,000 to $10,000, depending on the extent of the damage.
Reduces Mold and Mildew Risks: Mold can develop within 24-48 hours of water exposure, leading to potential health hazards.
Enhances Energy Efficiency: Properly sealed windows and doors can lower heating and cooling costs by 10-20%.
Increases Property Value: Waterproofing your windows and doors can boost home resale value by 5-7%.
Common Issues Caused by Poorly Sealed Windows and Doors
When windows and doors are not properly sealed, they can allow water to enter, causing:
Drafts and Heat Loss: Higher energy bills due to poor insulation.
Warping and Rotting: Moisture can damage wooden frames over time.
Mold and Mildew Growth: Leads to unhealthy indoor air quality.
Foundation Issues: Persistent leaks near entry points can weaken the home’s foundation.
