Why Window Caulking is Important

Why Window Caulking is ImportantWindows are an essential element of any home. They let light through and allow the air to flow inside the house. But they are essentially gaps in your home’s structure and can leak air and let in moisture. That’s where adding a sealant called caulking around your windows comes in. In this post, we take a look at what window caulking is and why it is important.

What is Window Caulking?

Caulking is an additional measure for insulating windows or other gaps, like doors and cracks. It involves sealing the windows with a flexible material that stops air from leaking in and out of the house.  You apply caulk with a pistol with a pointed end, which helps you get into the narrow space between the window frame and the wall, creating a seamless seal.

Which Windows Need Caulking?

Any window that connects the indoor to the outdoor should be caulked, as differences in temperature and pressure can lead to air leaks. This exchange through the windows can contribute to up to 30% of a home’s heating needs. Caulking significantly reduces that percentage.

Interior windows may also need caulking, especially in humid rooms like bathrooms, kitchens, or saunas. For caulking of indoor windows, you need to select a product with a safe composition.

Different Types of Caulking

There are different types of caulks that you can use depending on their purpose. You can choose from different foam types, but the most common ones are silicone, polyurethane, or latex-based.

Caulking is an effective way of sealing cracks, windows, doors, and other entry points, but you have to select the right caulk for the job. Here are some tips to help you choose the most suitable option:

  • For exterior window caulking, choose a water-proof product, resistant to heat and cold and non-degradable under direct sunlight. Silicone-based or poly caulks work best for this and can be used for garden hothouses, basement windows, and aluminium sliding doors.
  • When caulking windows in humid rooms, make sure the product is mildew and mould-resistant. Sealing a shower glass door or a bathroom window has to be done properly as there is much more moisture trapped in the room.
  • For indoor caulking, choose a paintable latex-based product. It will not release toxic fumes inside your house, and you can customize it to blend in perfectly after it has been set. Interior caulking is much more visible and should have a discreet finish.

When to Renew Your Window Caulking

Window caulking can last up to five years and more when properly maintained, but it has to be reapplied regularly. Caulking is useless if it doesn’t create a seal between the window and the exterior, so make sure to check it every year. When replacing caulking, ensure all of the old caulk is removed beforehand.

If you notice a draft coming from outside when the windows are closed or visible damage to the existing caulk, it’s time to replace it. Look for cracking, dryness, and peeling of the caulk, or if it looks dry and shrunk. Significant in your electricity bill or the presence of insects inside the house can also indicate a need to renew your window caulking.
