Proper Sealing of New Windows and Doors: Is It Essential to Keep Them Closed?

When a customer purchases new windows and doors for their home, one of the most common and perplexing questions facing them is whether they should keep the newly installed windows and doors closed for a couple of days after the installation. Many installers recommend this practice to ensure the windows and doors are properly sealed. But is it a standard operating procedure, or just a sales tactic?

Why Close Newly Installed Windows and Doors?

After a new window or door installation, it is not uncommon for customers to be advised by the installer to keep the windows and doors closed for a certain period. The installer might explain that this is required to allow the caulk sealant to dry and set. Caulk sealant is a crucial component of window and door installation, providing a waterproof barrier and helping to seal the gap between the window frame and the surrounding wall.

Risks of Not Sealing Properly

When window and door sealant is not allowed to set correctly, it can lead to several issues. Common problems include:

Leaks: A poorly sealed window can allow water to enter the home, leading to water damage and mold growth. Air Leakage: Improper sealing can result in increased air leakage, which can make the home less energy-efficient and increase heating and cooling costs. Tightness: If the windows and doors are not properly sealed, they may not fit their sills or tracks correctly, affecting their functionality.

Ensuring Proper Sealing

The process of ensuring proper caulking and sealing involves several steps. Firstly, the installer would fill the gaps between the window frame and the wall with a suitable sealant. Then, they would use a caulk gun to apply a consistent bead of sealant. Afterward, they might use a rubber squeegee or a flat edge to smooth and clean the sealant surface. Finally, the window or door would be closed for a period, often between one to three days, to allow the sealant to dry and set.

Is Keeping Windows Closed Standard Practice?

While many installers recommend keeping newly installed windows and doors closed for a couple of days, it is not a universally accepted standard operating procedure. The timeframe can vary based on the type of caulk used and the specific installation process followed. Some high-quality sealants do not require the windows and doors to be closed for an extended period.

This recommendation might also be influenced by the local climate and weather conditions. In areas with extreme temperatures or high humidity, it might be more critical to keep the windows and doors closed to ensure the sealant sets properly. However, in milder climates, the need for a closed period might be less stringent.

Alternatives to Keeping Windows Closed

There are several alternative methods to ensure proper window and door sealing:

Wait for Sealant to Set: Installers can provide instructions on when it is safe to open the windows and doors based on the specific caulk used and the weather conditions. Proper Caulk Selection: Using a high-quality, fast-setting sealant can reduce the need for a closed period. Preparedness: Customers can prepare a temporary solution, such as disassembling the windows and doors and repacking them for a few days, to avoid accidental opening.

Conclusion

In conclusion, while keeping newly installed windows and doors closed for a day or two can help ensure proper sealing, it is not always required. The specific timeframe might vary based on the type of caulk and the installation process. It is important for customers to discuss the recommended time with their installer and follow the guidelines provided to ensure the best possible outcome.
