Many older homes are notorious for their chilly drafts and high heating bills, often due to thin walls, aging windows, and gaps that let warm air escape. While modern insulation is effective, it can be costly and disruptive. Thankfully, simple, affordable fixes can drastically reduce drafts and improve comfort. These low-tech solutions don’t require major renovations, and can help you save energy and money. For more insights, check out these tips from Energy Saver.

Fabric draft stoppers, or “door snakes,” are an easy way to block cold air coming in under doors. You can buy them ready-made or create your own by filling a long fabric tube with rice, beans, or sand. While not as permanent as weatherstripping, draft stoppers are an affordable and reusable solution for both interior and exterior doors.

2. Install Heavy Curtains

Hanging thick, lined curtains can make a significant difference in keeping warmth indoors. Thermal or blackout curtains are especially effective at insulating windows and even doorways, far outperforming sheer or unlined curtains. For maximum effect, choose curtains made of dense fabrics like velvet or wool and ensure they reach the floor. Layering curtains—such as pairing thermal drapes over lighter sheers—can further boost insulation.

3. Seal Windows with Weatherstripping

Applying adhesive foam or rubber weatherstripping to window frames is a simple way to close gaps and block drafts. Foam strips are easy to install and inexpensive, while silicone weatherstripping offers greater durability and flexibility. Both options are affordable and can be removed later, making them ideal for renters or those preserving historic features.

4. Add Window Film

Clear plastic window film kits provide an extra layer of insulation by sealing windows and reducing heat loss through the glass. Shrink-wrap films use a hairdryer for a tight seal, while static-cling varieties adhere without adhesive and are easily removable. Both types allow natural light to enter while blocking cold drafts, making them ideal for winter use.

5. Block Chimneys When Not in Use

Unused fireplaces often allow significant drafts into your home. Inserting a chimney balloon or foam block can effectively seal the opening and prevent cold air from entering. While chimney blockers are designed for a snug fit, even a rolled-up towel can work as a temporary fix. Always remember to remove any blockage before lighting a fire.

6. Caulk Gaps and Cracks

Applying caulk to seal cracks around windows, baseboards, and exterior walls is a highly effective way to keep cold air out. Common places to check include corners, trim joints, and where pipes enter walls. Silicone caulk is best for non-porous surfaces like glass and metal, while latex caulk works well for wood and drywall. This affordable fix delivers lasting results and can significantly improve your home’s energy efficiency.

7. Lay Down Rugs and Carpets

Area rugs and carpets provide valuable insulation on hardwood or tile floors, helping to block drafts that seep up through floorboards. Wool rugs offer excellent warmth, while synthetic options are affordable and easy to clean. Layering rugs can further enhance insulation and comfort, especially in high-traffic or particularly cold rooms.

8. Insulate the Attic Hatch

An uninsulated attic hatch is a common source of heat loss in old homes. Adding foam board insulation to the hatch door and sealing its edges with weatherstripping can stop cold drafts and keep warm air inside. While full attic insulation is a bigger project, insulating the hatch is a quick, low-cost fix with immediate benefits.

9. Use Temporary Magnetic Vent Covers

Temporary magnetic vent covers can be placed over unused metal heating or cooling vents to block drafts in rooms that aren’t being heated. These covers are simple to install and remove, making them perfect for seasonal use. Compared to plastic or cloth vent covers, magnetic types provide a tighter seal and are reusable year after year.

10. Rearrange Furniture to Block Drafts

Placing large pieces of furniture such as bookshelves, sofas, or cabinets against exterior walls or near drafty windows creates an extra barrier to cold air. While not as comprehensive as insulation or sealing, this low-effort solution can noticeably reduce drafts and increase comfort. It’s a quick fix that requires no tools or materials.
