Windows can be a significant source of energy loss in your home, allowing drafts to come in and increasing heating and costs. One effective way to prevent this is by silicone sealing your windows. In this guide, we will walk you through the steps of applying mastic to your windows for improved energy efficiency and draft protection. 
Benefits Of Sealing Your Windows 
Improved energy efficiency : Sealing gaps around windows with silicone can help reduce heat loss in the winter and prevent cool air from escaping in the summer, which can save you money on energy bills. 
Draft protection : Silicone sealing can prevent drafts from entering your home, making it more comfortable and reducing the need for additional heating or cooling. 
Moisture protection : Sealing around windows can help prevent moisture from seeping in, which can lead to water damage and mold growth. 
Noise reduction : Sealing gaps around windows can help reduce outside noise from entering your home, making it quieter and more peaceful inside. 
Gather Materials :  
Silicone sealant : Choose a high-quality low modulus silicone sealant designed for windows. 
Silicone application gun : You will need a caulking gun to apply the sealant. 
Sealant Tool : A scraper can help you smooth the sealant. 
Clean rag or Blue Roll : Use a clean rag to wipe away excess sealant. 
Masking tape : You may need masking tape to protect surrounding surfaces. 
Stanley Knife : You may need a utility knife to remove old sealant. 
Silicone Application  
Load the silicone sealant into the application gun, cut the nozzle at a 45 degree angle to the thickness desired, apply a bead of sealant along the gap between the window frame and the wall. Apply enough sealant to fill the gap but not so much that it will spill over. Use your Silicone tool to smooth the silicone making sure to not apply too much pressure and creat a nice even line. Give the silicone adequete time to dry this is typically 24 - 48 hours depending on the environment and type of silicone used, refer to the manufacturers instruction on the tube for information on drying times.  
Mistakes to avoid  
Not cleaning the window properly : Make sure to clean the window thoroughly before applying the sealant, or the sealant may not adhere properly. 
Applying too much sealant : Applying too much sealant can cause it to spill over and create a mess. 
Not smoothing the sealant : If you don't smooth the sealant, it may not create a good seal, allowing drafts to come in. 
Not letting the sealant dry : If you don't let the sealant dry properly, it may not adhere properly and may not provide the intended benefits. 
Silicone sealing your windows is an easy DIY project that can provide many benefits, such as improved energy efficiency, draft protection, and moisture protection. By following the steps in our guide, you can successfully seal your windows and enjoy the benefits it provides. Remember to take your time, use high-quality materials, and check for gaps regularly to maintain the effectiveness of the seal.
