How to Fix Air Leaks and Minimise Drafts

Air leaks and drafts can make your home less comfortable and increase energy costs. Sealing these leaks is essential for maintaining a cosy and energy-efficient home. Follow these steps to fix air leaks and minimise drafts effectively.

Tools and Materials You Will Need

• Weatherstripping
• Door sweep
• Foam tape
• Draft stopper
• Caulk and caulking gun
• Utility knife or scissors
• Measuring tape
• Screwdriver
• Hammer and nails (if needed)
• Insulating door panel kit (optional)

Steps to Fix Air Leaks and Minimise Drafts

Step 1: Identify Air Leaks

1. Inspect Doors and Windows: Check for gaps and cracks around doors and windows where air can enter.
2. Feel for Drafts: On a windy day, feel around the edges of doors and windows for drafts.
3. Use a Candle or Incense Stick: Hold a lit candle or incense stick near the edges of doors and windows. If the flame flickers or the smoke moves, you have found an air leak.

Step 2: Apply Weatherstripping

1. Select the Right Type: Choose weatherstripping suitable for your doors and windows. Options include adhesive foam tape, V-strip, and rubber weatherstripping.
2. Measure and Cut: Measure the sides and top of the door frame to determine the length of weatherstripping needed. Cut to size using a utility knife or scissors.
3. Install Weatherstripping: Apply the weatherstripping to the door frame, ensuring a snug fit. Peel off the adhesive backing and press firmly into place.

Common Types of Weatherstripping and Uses

Type	Best For	Installation Method
Adhesive Foam Tape	Gaps around door frames	Peel and stick
V-Strip	Tight, even gaps	Peel and stick, or use nails for security
Rubber Weatherstripping	Heavy-duty, frequent use areas	Screw or nail into place

Step 3: Install a Door Sweep

1. Measure the Door Width: Measure the width of the door to determine the length of the door sweep needed.
2. Cut the Door Sweep: If necessary, cut the door sweep to fit the width of the door using a utility knife or saw.
3. Attach the Door Sweep: Align the door sweep with the bottom edge of the door. Use screws or nails to secure it in place.

Step 4: Use Foam Tape

1. Measure the Door Jamb: Measure the sides and top of the door jamb to determine the length of foam tape needed.
2. Cut and Apply Foam Tape: Cut the foam tape to size, peel off the backing, and press it firmly into place along the door jamb.

Step 5: Seal Gaps with Caulk

1. Identify Gaps: Look for gaps and cracks around the door frame, particularly where the frame meets the wall.
2. Apply Caulk: Use a caulking gun to apply a bead of caulk along the gaps. Smooth the caulk with your finger or a caulk smoothing tool.
3. Let It Dry: Allow the caulk to dry completely according to the manufacturer's instructions.

Step-by-Step Summary Table

Step	Action
Identify Air Leaks	Inspect, feel for drafts, use candle/incense
Apply Weatherstripping	Measure, cut, and apply to door frame
Install Door Sweep	Measure, cut, and attach to bottom of door
Use Foam Tape	Measure, cut, and apply to door jamb
Seal Gaps with Caulk	Identify gaps, apply caulk, and smooth

Step 6: Add a Draft Stopper

1. Choose a Draft Stopper: Select a draft stopper that fits the style and needs of your door. Options include fabric stoppers, weighted stoppers, and adjustable stoppers.
2. Place the Draft Stopper: Position the draft stopper at the base of the door to block drafts.

Step 7: Insulate Doors and Windows (Optional)

1. Insulating Door Panels: Install insulating panels on doors and windows for additional protection against drafts.
2. Window Insulation Kits: Use window insulation kits to cover windows and prevent air leaks.
