<h1>Window Draft Sealing</h1>
<p>This guide provides a step-by-step approach to identify and seal drafty windows. The aim is to improve home insulation and energy efficiency by using simple sealing techniques.</p>

<h3>Step 1: Identify Drafts</h3>
<p>Check all windows in your home for drafts by using the hand test—feel for cool air near the edges. Alternatively, use a candle or incense stick to see if smoke moves, indicating airflow. Perform these tests on a windy day or when the difference between indoor and outdoor temperatures is noticeable for the best results.</p>

<h3>Step 2: Clean Surfaces</h3>
<p>Clean all window frames and sashes thoroughly with soap and warm water. Remove any dust, dirt, and grime, as these can prevent sealing materials from adhering properly.</p>

<h3>Step 3: Choose Sealant</h3>
<p>Select a suitable sealant based on the type of window and the extent of the drafts. Options include weatherstripping, caulk for non-moving parts, and shrink film for a more temporary solution.</p>

<h3>Step 4: Apply Weatherstripping</h3>
<p>For movable parts of the window, like the sash, apply self-adhesive foam, rubber weatherstripping, or felt. Make sure the window can still open and close smoothly after application.</p>

<h3>Step 5: Apply Caulk</h3>
<p>Use silicone-based caulk to seal non-moving parts of the window, such as where the window frame meets the wall. Caulk both the interior and exterior, if accessible, to ensure a complete seal. Smooth out the caulk with a caulk tool or a damp finger for a clean finish.</p>

<h3>Step 6: Install Shrink Film</h3>
<p>If using shrink film, apply double-sided tape around the window frame, attach the film, and heat it with a hairdryer to 'shrink' it into place, providing an airtight seal.</p>

<h3>Step 7: Inspect Seals</h3>
<p>After the sealants have cured or set, inspect the work by repeating the draft test. Ensure there are no air leaks and the window operates as intended.</p>

<h2>General Notes</h2>

<h3>Safety First</h3>
<p>Ensure you use the ladder securely and safely if you need to seal high windows, and always follow the manufacturer's instructions for any sealing products.</p>

<h3>Caulk Season</h3>
<p>The best time to apply caulk is during dry weather when the outdoor temperature is above 45°F (7°C) for at least three days.</p>

<h3>Regular Checks</h3>
<p>Do regular checks for drafts and reapply sealants as needed, especially before winter, to maintain energy efficiency.</p>
