Draught-proofing your doors is a simple and cost-effective way to improve your home's energy efficiency, helping you save on heating bills. In this guide, we'll walk you through the steps to ensure your doors are well-sealed against draughts.
Key Takeaways
- Draught-proofing can reduce energy bills significantly.
- Proper sealing prevents heat loss, improving home comfort.
- Affordable solutions like adhesive strips and door sweeps are widely available.
Before You Start
Before you dive into draught-proofing, it's important to have the right materials and tools on hand. Here's what you'll need:
- Draught excluders: Varieties include adhesive strips and door sweeps.
- Tools: Tape measure, scissors, and a screwdriver.
- Preparation: Check the condition of the door and frame for any damage.
By sealing your doors, you can enjoy greater energy savings, which complement other insulation methods like solid wall insulation.
Step 1: Assess Your Doors
Start by identifying areas where draughts are entering. Close the door and feel around the edges for air movement. Pay special attention to the bottom and sides of the door.
- Why it matters: Identifying draughts helps target your efforts effectively.
- If skipped: You may miss smaller gaps, resulting in persistent draughts and higher energy bills.
Step 2: Choose the Right Draught Excluders
Draught excluders come in various types. Here are the most common options available in the UK:
- Adhesive Strips: Easy to install and ideal for minor gaps.
- Door Sweeps: Perfect for sealing gaps at the bottom of the door.
- Brush Strips: Great for larger gaps and can be used on uneven surfaces.
As of 2026, draught excluders typically cost between £5 and £20 each, depending on the type and brand.
Step 3: Install Adhesive Strips
Adhesive strips are a quick solution for sealing gaps around the door frame.
- Clean the Surface: Wipe down the frame to ensure the adhesive sticks properly.
- Measure and Cut: Measure the length of each side of the door, then cut the strips to size.
- Apply the Strips: Carefully stick the adhesive to the frame, pressing firmly to ensure a good seal.
- Why it matters: Proper installation ensures maximum effectiveness.
- Common mistakes: Avoid stretching the strip too much, as it can weaken the adhesive.
Step 4: Fit a Door Sweep
Door sweeps help seal the gap between the door and the floor.
- Measure the Door Width: Use a tape measure to find the width of the door.
- Cut the Sweep to Size: Trim the sweep to match the door's width.
- Attach the Sweep: Use screws or adhesive to secure it to the bottom of the door.
- Why it matters: This prevents draughts from entering underneath.
- If skipped: You'll face increased energy costs due to heat loss.
Step 5: Seal Keyholes and Letterboxes
These often-overlooked areas can let in significant draughts.
- Keyholes: Use a purpose-made cover or escutcheon to seal off draughts.
- Letterboxes: Install a brush or flap to keep out cold air.
Sealing these areas is crucial for full draught-proofing. For other doors, consider our guide on insulating garage doors.
Common Mistakes to Avoid
- Incorrect Measurements: Always measure twice to ensure a snug fit.
- Poor Material Choice: Select materials suited for your door type to maximise energy savings.
Benefits of Effective Draught-Proofing
Draught-proofing offers several benefits:
- Energy Savings: You can reduce heating bills by up to 15%, according to the Energy Saving Trust.
- Improved Comfort: Say goodbye to cold spots and enjoy a more consistent indoor temperature.
Draught-proofing is an excellent complement to other insulation efforts, such as attic insulation.
Checklist
- Assess doors for draughts.
