Sealing Drafty Windows and Doors

Difficulty: (Moderate)

Time Needed: (30-60 minutes)

Drafty windows and doors can lead to higher energy bills by allowing cold air in during the winter and letting cool air escape in the summer. Sealing these gaps can improve your home's energy efficiency. Here's a detailed guide to sealing drafty windows and doors:

Tools Needed:

  • Weatherstripping or caulk
  • Caulk gun (if using caulk)
  • Scissors or utility knife
  • Measuring tape
  • Putty knife (optional)
  • Rags or paper towels

Steps for Using Weatherstripping:

  1. Inspect and Clean the Area:
    • Check the windows and doors for gaps and drafts. Inspect around the frames, sashes, and edges.
    • Clean the area thoroughly with a rag to ensure the weatherstripping adheres properly. Remove any dust, dirt, or old adhesive.
  2. Measure the Area:
    • Use a measuring tape to measure the length of the gaps you need to seal.
    • Cut the weatherstripping to the appropriate lengths with scissors or a utility knife.
  3. Apply the Weatherstripping:
    • Peel off the backing from the adhesive side of the weatherstripping.
    • Press the weatherstripping firmly into place along the edges of the window or door frame. Make sure it creates a tight seal when the window or door is closed.

Steps for Using Caulk:

  1. Inspect and Clean the Area:
    • Identify the gaps and drafts around windows and doors.
    • Use a putty knife to remove any old caulk or debris from the area.
    • Clean the surface with a rag and ensure it is dry before applying new caulk.
  2. Prepare the Caulk Gun:
    • Cut the tip of the caulk tube at a 45-degree angle to the desired width of the bead.
    • Load the tube into the caulk gun.
  3. Apply the Caulk:
    • Hold the caulk gun at a consistent angle and apply a steady bead of caulk along the gaps.
    • Smooth the caulk with your finger or a caulking tool to ensure it fills the gap and adheres properly.
  4. Clean Up:
    • Wipe away any excess caulk with a rag or paper towel before it dries.
    • Allow the caulk to dry according to the manufacturer's instructions before painting or closing the window/door.

Tips:

  • Choose the right type of weatherstripping or caulk for your needs. Foam weatherstripping is great for doors, while silicone caulk works well for windows.
  • For large gaps, consider using expanding foam sealant for a better seal.
  • Regularly inspect your windows and doors for new drafts and reseal as necessary.
