Where Do I Need to Caulk Windows?

Because windows are one of the main ways that energy can escape your home, investing in high-quality windows that are both durable and energy efficient should always be a high priority. Additionally, homeowners should make sure to care for windows properly, and window caulking is a necessary part of the maintenance required to protect your home from energy loss.

Window caulking is performed to reinforce the sealant covering the gaps between the window and their frames. Though it may sound simple enough, the process can be a bit complicated and requires the assistance of expert window installers to ensure it’s done properly. While caulking, when done correctly, can improve your home’s insulation and prevent energy loss; window caulking can also do more harm than good if performed poorly.

We’re experts on window installation and maintenance and have put this post together to help you understand more about window caulking and exactly where to caulk for the most effective maintenance possible.

Where to Avoid Caulking Your Windows

Many people think that the more insulation and caulking, the better. The logic is sound: fewer gaps will result in a reduced transfer of temperature. When it comes to window caulking, however, less can be more. Here are the areas to avoid caulking on windows for maximum efficiency:

Avoid the Weep Hole: On the exterior frame of vinyl windows, there is a small hole at the bottom. This hole allows moisture from behind the window to exit through the frame. If this hole is blocked, then this can lead to a buildup of moisture that can then lead to mold and rot.

Above the Window Frame: If you caulk above the window frame then you stand to block the drip edge. This edge carries away water and other liquids from your windows and siding. Without this joint, you once again run the risk of building up moisture behind your window, which can be terrible news for your siding and window frames.

Where the Window Meets the Siding: The siding and trim on your window can dictate whether you should place caulk here. If there is a flush fit then you should perform the caulking, otherwise not. If you decide to caulk there you should use a weather-proof silicone caulk that can resist the elements. Making this call is a tricky one and one of the reasons that you will want to rely on assistance from expert window installers.

Moveable Parts: Obviously you will want to avoid sealing any moving parts on your windows! You should look out for these areas and be extra diligent when it comes to window caulking. Companies offering DFW windows services will be able to help you with this.

When the Window Trim Sits Above the Siding: Siding on modern homes generally goes all the way up to the window trim. This means that window caulking is unnecessary here because it is already properly insulated. In fact, you could even do more harm to your property by caulking here as it will act as a vehicle for moisture.

Where to Caulk Your Windows

The actual areas of the windows that you’ll need to caulk will depend on the type of window you have. For example, vinyl and fiberglass siding and frames are generally much stronger and durable than wood materials, and all three will have varying maintenance requirements to consider. In fact, you’re likely to need to use different caulking substances for different types of window materials. Find out what the manufacturer recommends before applying caulk to your window products for the very best outcome.
