Drafts and air leaks around windows and doors can significantly impact your home's comfort and energy efficiency. This guide will help you identify problem areas and provide effective solutions to seal air leaks and eliminate drafts.
Identifying Air Leaks
Common Signs of Air Leaks
- Noticeable drafts near windows or doors
- Frost or ice buildup on windows in winter
- Rattling or whistling sounds when it's windy
- Higher than expected energy bills
- Difficulty maintaining consistent temperatures
How to Locate Air Leaks
1. Visual Inspection
Check for visible gaps around window and door frames, especially where different building materials meet.
2. Hand Test
On a windy day, feel for air movement around windows and doors with the back of your hand.
3. Candle Test
Hold a lit candle near window and door edges on a windy day. If the flame flickers, you've found a draft.
4. Professional Energy Audit
Consider a professional energy audit that includes a blower door test to identify all air leaks in your home.
DIY Solutions for Sealing Air Leaks
1. Weatherstripping
Ideal for sealing movable components like doors and operable windows:
- V-strip (tension seal): Good for the sides of double-hung windows
- Foam tape: Easy to apply around door frames
- Door sweeps: For the bottom of exterior doors
- Door shoe: For exterior doors with uneven thresholds
2. Caulking
Best for stationary components like window frames and door jambs:
- Remove old, cracked caulk completely before applying new
- Use a high-quality, paintable silicone or acrylic latex caulk
- Apply in a continuous, even bead
- Smooth with a wet finger or tool for a professional finish
3. Window Insulation Kits
An affordable solution for seasonal insulation:
- Plastic film that shrinks when heated with a hair dryer
- Creates an additional air barrier
- Can be removed in warmer months
- Ideal for older, drafty windows
When to Consider Window Replacement
If you're experiencing persistent drafts despite repairs, it might be time to consider new, energy-efficient windows. Look for these signs:
- Windows that are difficult to open or close
- Visible damage to frames or sashes
- Condensation between window panes
- Noticeable outside noise infiltration
- High energy bills despite weatherization efforts
