# Window Draft Sealing
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.

### Step 1: Identify Drafts
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.

### Step 2: Clean Surfaces
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.

### Step 3: Choose Sealant
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.

### Step 4: Apply Weatherstripping
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.

### Step 5: Apply Caulk
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.

### Step 6: Install Shrink Film
If using shrink film, apply double-sided tape around the window frame, attach the film, and heat it with a hairdryer to &#x27;shrink&#x27; it into place, providing an airtight seal.

### Step 7: Inspect Seals
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.

## General Notes

### Safety First
Ensure you use the ladder securely and safely if you need to seal high windows, and always follow the manufacturer&#x27;s instructions for any sealing products.

### Caulk Season
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.

### Regular Checks
Do regular checks for drafts and reapply sealants as needed, especially before winter, to maintain energy efficiency.
