Understanding the Importance of Sealing

Before diving into the how-to, it's important to understand why sealing gaps and leaks around windows and doors is necessary:

  • Energy Efficiency: Proper sealing keeps the warm or cool air inside, making your home more energy-efficient.
  • Cost Savings: By reducing the air leakage, you can lower the costs of heating and cooling your home.
  • Comfort: Sealing eliminates drafts that can cause discomfort during colder seasons.
  • Prevent Moisture and Dirt: Sealing gaps helps in preventing moisture and dirt from entering the house, which can cause mold and other issues.

Tools and Materials Needed

To get started, you will need the following tools and materials:

  • Caulking gun
  • Weatherstripping
  • Silicone or acrylic latex caulk
  • Expanding foam sealant
  • Putty knife

Step 1: Inspect Windows and Doors

Begin by inspecting all windows and doors for gaps and drafts. Pay special attention to corners and where the frame meets the wall.

Step 2: Choose Your Sealant

  • Weatherstripping: Ideal for movable components like the edges of doors and operable windows.
  • Caulk: Best for stationary cracks and gaps less than 1-quarter-inch wide around door and window frames.
  • Expanding Foam: Suitable for larger gaps around windows and baseboards.

Step 3: Prepare the Surface

Clean all areas to be sealed. Remove any old caulk or weatherstripping and ensure surfaces are dry and free of dust and debris.

Step 4: Apply Weatherstripping

Cut the weatherstripping to fit each side of the window or door. Peel and stick, or nail into place depending on the type of weatherstripping you are using.

Step 5: Caulk Gaps

Load the caulk into the caulking gun. Apply caulk smoothly and steadily around the frame where the window or door meets the wall. Smooth the caulk with a putty knife or your finger (wet it slightly first).

Step 6: Seal Larger Gaps

For gaps larger than 1-quarter-inch, use expanding foam. Shake the can well, and spray the foam slowly and evenly into the gap. Allow it to expand and cure as per the manufacturer's instructions.
