Keeping your home comfortable and energy-efficient is one of the smartest things you can do as a homeowner. Heating and cooling account for nearly half of the average American home’s energy use, so even small changes can have a big impact. Weatherizing helps prevent energy loss, lowers utility bills, and creates a more comfortable living environment year-round.

Below are practical and homeowner-friendly steps you can take to weatherize your home in 2026, along with helpful resources and related guides from our blog.

Start With an Energy Analysis

An energy audit will show you where your home is losing heat or cool air and what improvements will make the biggest difference. Many local utility companies offer low or no-cost assessments and can connect you with approved contractors.

If you want to explore rebate programs or incentives available in your area, the Department of Energy’s Rebate Finder is a great place to start.

Improve Attic and Roof Insulation

Attics are one of the biggest sources of energy loss, especially in older homes. Good insulation keeps warm air inside during winter and blocks outdoor heat during summer.

A few helpful reminders:

• Unfaced insulation is suitable for attic floors

• Faced insulation works well on the underside of the roof

• Higher R-values mean better insulation

• Even if your attic is insulated, it might not be insulated enough

While you are in the attic, use spray-can foam to seal gaps around light fixtures, attic stairs, or HVAC runs.

If you need an insulation contractor, we would be happy to refer trusted professionals.

Add Protection to Basements and Crawl Spaces

Basements and crawl spaces are prone to moisture and air leaks. If you notice dampness, drafts, or musty smells, consider taking preventative action.

For mild to moderate leaks, a vapor barrier can help reduce moisture and improve insulation. For more serious water issues, consider interior drainage or sump pump systems.

Apply Weather Stripping to Leaky Windows and Doors

Weather stripping is an easy way to stop drafts and is one of the most cost-effective upgrades you can make. Silicone strips are durable and long lasting.

We recommend Frost King Silicone Weatherseal for a reliable seal around doors and windows.

Seal HVAC Duct Leaks

Leaky ductwork forces your heating and cooling system to work harder than it should. Most HVAC contractors offer duct-sealing services, which can significantly improve efficiency. If you are unsure who to call, we can connect you with our trusted providers.

Improve Window Efficiency

Old windows can let out a lot of heat in the winter and cool air in the summer. Window upgrades can dramatically improve efficiency, but there are budget-friendly alternatives to full replacement.

Consider:

• Installing low-E storm windows

• Sealing gaps with caulk

• Adding solar screens to sunny exterior windows

Solar screens can reduce heat absorption significantly. Learn more about solar screens from a reputable local provider.

Switch to LED Lighting

LED bulbs last longer, use less energy, and are available in a range of brightness and warmth levels. Replacing older bulbs is one of the simplest ways to lower your energy bills.
