Winter in Cleveland can be harsh, and cold drafts sneaking into your home can make it uncomfortable while driving up heating costs. Fortunately, there are several budget-friendly and effective ways to prevent cold drafts and keep your home warm. Here’s how you can seal up your space and improve energy efficiency this winter.
1. Identify Drafty Areas
Before sealing drafts, you need to find the problem areas where cold air is sneaking in.
How to Check for Drafts:
- Use your hand to feel for cold air near doors, windows, and outlets.
- Hold a candle or incense stick near suspected drafty areas; if the smoke moves, there’s a leak.
- Use an infrared thermometer or schedule a home energy audit for a detailed inspection.
Common Drafty Areas:
- Windows and doors
- Electrical outlets and switch plates
- Fireplace dampers
- Baseboards and flooring gaps
- Attics and crawl spaces
2. Seal Windows with Weatherstripping and Caulk
Windows are a major source of heat loss in winter. Sealing them properly can make a huge difference.
Best Fixes for Drafty Windows:
- Weatherstripping – Apply adhesive foam or rubber weatherstripping along the window edges to block cold air.
- Caulking – Use silicone or latex caulk to seal cracks or gaps around window frames.
- Plastic Window Film – Affordable and easy to install, plastic insulation kits create an extra air barrier.
Pro Tip: Layer thermal curtains over windows to further insulate against the cold.
3. Stop Drafts from Doors
Doors that don’t seal properly can let in freezing air. Prevent this with a few quick fixes.
How to Insulate Drafty Doors:
- Door Sweeps – Install under exterior doors to block air leaks at the bottom.
- Foam Weatherstripping – Apply around the door frame to create a snug seal.
- Draft Stoppers (Door Snakes) – A simple, low-cost fix for blocking cold air along the floor.
Pro Tip: Check your garage door seal as well—replacing worn-out seals helps keep cold air out of attached garages.
4. Insulate Electrical Outlets and Switch Plates
Many homeowners don’t realize that electrical outlets and light switches on exterior walls can leak cold air.
Easy Fix:
- Install foam outlet gaskets behind switch and outlet covers to create an extra insulation layer.
- Use childproof plug covers in rarely used outlets to prevent airflow.
Pro Tip: This small upgrade is inexpensive but can make a noticeable difference in keeping rooms warmer.
5. Use Heavy Curtains and Rugs for Extra Insulation
Windows and floors can let in a surprising amount of cold air, even with proper sealing.
How to Add Warmth to Your Home:
- Thermal Curtains – Block drafts and keep heat inside.
- Rugs and Carpets – Cover bare floors, especially over tile or hardwood, which get cold in winter.
- Door Curtains – A thick fabric curtain over doors leading to garages or patios can add another layer of insulation.
Pro Tip: Let the sun in during the day by opening curtains on south-facing windows, then close them at night to retain heat.
6. Seal Gaps in Baseboards and Floors
Small gaps between baseboards, flooring, or walls can allow cold air to creep in.
How to Fix Baseboard Drafts:
- Use caulk or foam sealant to fill cracks between baseboards and walls.
- Add draft-blocking tape under trim if gaps are significant.
- Consider area rugs to insulate against cold floors.
7. Check Your Fireplace for Leaks
Fireplaces can be a major source of heat loss if not properly sealed.
How to Prevent Fireplace Drafts:
- Close the damper when not in use to block airflow.
- Install a chimney balloon or draft stopper to seal unused fireplaces.
- Use glass fireplace doors to reduce heat loss.
Pro Tip: If you use your fireplace frequently, consider a heat-exchange system to circulate warm air into the room.
8. Add Attic and Crawl Space Insulation
A poorly insulated attic or crawl space can let in cold air and drive up heating bills.
Best Insulation Fixes:
- Check attic insulation levels – If insulation is thin or patchy, adding fiberglass batts or blown-in insulation can help retain heat.
- Seal attic entry points with weatherstripping to prevent air leaks.
- Insulate crawl spaces with foam board or spray foam insulation to block cold drafts from below.
Pro Tip: Homeowners in Cleveland may qualify for energy rebates when upgrading insulation. Check local energy programs for savings.
9. Maintain Your Heating System
A well-maintained furnace heats your home more efficiently, reducing cold spots and drafts.
Winter HVAC Maintenance Tips:
- Change air filters every 1-3 months to improve airflow and efficiency.
- Have your furnace inspected before peak winter months.
- Check and seal ductwork for any air leaks, especially in attics and basements.
Pro Tip: If your furnace is over 15 years old, upgrading to an energy-efficient model can save money on heating bills in the long run.
10. Use Smart Home Heating Strategies
Beyond sealing drafts, smart temperature control can keep your home warmer and more efficient.
Smart Heating Tips:
- Set your thermostat to 68°F during the day and lower at night to save energy.
- Use space heaters wisely, only in occupied rooms.
- Reverse ceiling fans to push warm air down into living areas.
Pro Tip: A smart thermostat can learn your heating preferences and adjust temperatures automatically for maximum efficiency.
Colin’s Key Points
- Check for drafts using a candle test and seal problem areas first.
- Weatherstrip windows and doors to prevent heat loss.
- Insulate electrical outlets and baseboards to block hidden leaks.
- Use thermal curtains, rugs, and door sweeps for extra warmth.
- Upgrade attic insulation and maintain your heating system for long-term energy savings.
- Smart thermostats and efficient heating habits can help reduce winter heating costs.
