How to Weatherproof Your Home for Energy Efficiency

Rain, rain, go away, and don’t come back! This is a thought any of us have had if you’ve experienced weather not staying outside where it belongs. We want you to feel comfortable all year in your Energy Smart home. Weatherproofing your home is one of the most effective ways to do just that since it reduces energy costs and maintains a comfortable indoor temperature year-round. By sealing air leaks, improving insulation, and upgrading windows and doors, you can prevent heat loss in winter and keep cool air inside during summer. Here’s how to make your Energy Smart home more energy-efficient through proper weatherproofing.

Seal Air Leaks Around Windows and Doors

One of the biggest culprits of energy loss is air leaks around windows and doors. Even small gaps can let in drafts, making your heating and cooling system work harder.

• Use weatherstripping – Apply self-adhesive weatherstripping around window and door frames to block gaps.
• Apply caulking – Seal small cracks and openings with exterior-grade caulk to prevent air leaks.
• Install a door sweep – A door sweep at the bottom of exterior doors helps block cold air from entering.

Upgrade Your Insulation

Proper insulation keeps heat from escaping in the winter and prevents excessive heat gain in the summer. Key areas to focus on include:

• Attic insulation – Heat rises, so adding insulation in the attic can significantly improve energy efficiency.
• Wall insulation – If your home has insufficient insulation, consider adding spray foam or fiberglass batts.
• Basement and crawlspace insulation – Insulating these areas helps prevent cold floors and reduces energy loss.

Install Energy-Efficient Windows and Doors

Older windows and doors may not provide proper insulation, leading to higher energy bills.

• Upgrade to double- or triple-pane windows – These windows contain insulating gas layers that improve energy efficiency.
• Use thermal curtains – Thick, insulated curtains can help keep warm air inside during winter and block heat during summer.
• Install storm doors – A storm door adds an extra layer of insulation, reducing drafts.

Protect Your Home’s Exterior

Your home’s exterior plays a crucial role in weatherproofing.

• Inspect and repair siding – Cracked or damaged siding allows moisture and air infiltration.
• Seal exterior wall gaps – Use expanding foam or caulk to fill gaps around pipes, vents, and utility openings.
• Check the roof and gutters – A well-maintained roof and clean gutters prevent water damage that could lead to insulation issues.

Maintain Your HVAC System

A well-functioning heating and cooling system improves energy efficiency.

• Change air filters regularly – Dirty filters reduce airflow and force your HVAC system to work harder.
• Schedule regular maintenance – Have a professional inspect your system to ensure optimal performance.
• Use a programmable thermostat – Adjusting temperatures based on your schedule can help reduce energy waste.

Weatherproof Your Floors

Floors, especially in older homes, can be a source of drafts and heat loss.

• Use area rugs – Rugs add an insulating layer and help keep floors warmer in winter.
• Seal gaps in floorboards – Use caulk or wood filler to close gaps in wooden floors.
• Add underfloor insulation – Insulating the floor above unheated spaces can improve efficiency.

Weatherproofing Saves Energy and Lowers Costs

Just a few simple steps stand between you and being cozy in your Energy Smart home. By taking the steps we mentioned above to seal air leaks, improve insulation, and upgrade windows and doors, you can enhance your home's energy efficiency while reducing heating and cooling costs. Weatherproofing not only makes your home more comfortable but also helps the environment by reducing energy consumption.
