My old house has quite a few drafty windows and doors, especially as we head into the colder months. I've tried some basic weatherstripping and caulk, but I'm still feeling a noticeable chill in certain areas. What are the most effective and long-lasting methods for sealing drafts around windows and doors? Are there specific types of materials or techniques that DIYers should prioritize? I'm looking for advice on everything from temporary fixes to more permanent solutions that could improve energy efficiency.

For sealing drafty windows and doors, prioritize these DIY methods:

Temporary Fixes (Easy & Affordable):

• Window Insulation Film Kits: Heat-shrink plastic film applied to the interior frame with double-sided tape. Very effective for single-pane windows.

• Draft Stoppers/Snakes: Fabric tubes filled with rice or sand placed at the bottom of doors/windows.

• Thermal Curtains: Heavy, insulated curtains create a barrier against drafts.

• Removable Caulk/Mortite: Apply to gaps, easily removed when warmer.

• Adhesive-Backed Foam Tape: Simple to apply to seal small, non-moving gaps.

More Permanent Solutions (DIY with lasting impact):

• Weatherstripping: Replace old, worn weatherstripping with new rubber, silicone, or V-strip types around operable windows and doors.

• Caulking: Seal stationary gaps and cracks around window and door frames (where they meet the wall) with high-quality, flexible silicone caulk for exterior and paintable acrylic latex for interior.

• Door Sweeps: Install a new sweep along the bottom of exterior doors to seal the gap with the threshold.

• Reglazing: For older windows, re-glaze loose panes with glazing compound.

• Expanding Foam Sealant: Use for larger, non-moving gaps (e.g., between window frame and rough opening), being careful with "window and door" specific foams that expand less to avoid bowing frames.

Prioritize:

1. Identify Leaks: Use a lit candle or incense stick to find drafts.

2. Clean Surfaces: Ensure all surfaces are clean and dry for optimal adhesion of caulk and weatherstripping.

3. Layer Solutions: Combine methods for best results (e.g., caulk and weatherstripping on a window, plus an insulation kit in winter).
