Seasonal changes can take a toll on your home—especially if your doors and windows aren’t properly sealed. Drafts, leaks, and temperature fluctuations not only make your space uncomfortable but also increase energy costs. Luckily, with a few key steps, you can weatherproof your doors and windows for all seasons to ensure comfort and efficiency throughout the year.
At Tashman Home Center, we’re here to help Los Angeles homeowners create energy-efficient, weather-tight homes that are built to handle the heat of summer and the chill of winter. Read this article to learn how you can prep your doors and windows for every season.
Why Weatherproofing Matters
Weatherproofing isn’t just a seasonal fix—it’s a smart, long-term strategy. Taking the time to seal and insulate your home has multiple benefits:
- Reduce heating and cooling costs: Drafts around windows and doors can cause your HVAC system to work overtime, resulting in higher utility bills. Proper sealing helps regulate indoor temperature efficiently.
- Improve indoor comfort: Say goodbye to cold spots in winter or overheated rooms in summer. Weatherproofing keeps your home cozy all year.
- Minimize outside noise: Sealing up gaps not only blocks air but also muffles noise from traffic, construction, and other outdoor sources.
- Prevent moisture damage and mold: Gaps and leaks can allow water to seep in, potentially damaging walls, floors, and insulation while creating an environment for mold growth.
Whether you’re in the middle of a remodel or simply prepping your home for seasonal changes, weatherproofing is a smart investment in your comfort, health, and wallet.
Step-by-Step Guide to Weatherproofing Your Doors and Windows
1. Inspect for Leaks and Drafts
Start with a thorough inspection of your home. Look for signs of air leaks, such as:
- Drafts on windy days
- Light peeking through seals at night
- A dollar bill sliding easily out of closed windows or doors
You can also try holding a lit incense stick near the edges of doors and windows. If the smoke wavers, there’s a draft that needs attention. Identifying problem areas is the first step toward a fully sealed, weatherproof home.
2. Apply Weatherstripping
Weatherstripping is one of the simplest and most cost-effective ways to seal gaps around doors and windows. It creates a barrier that prevents outside air from entering and indoor air from escaping. Here are a few types to consider:
- Foam Tape: Easy to apply and ideal for sealing windows or irregular gaps.
- V-Strips (Tension Seal): Excellent for the sides of double-hung windows and door jambs.
- Door Sweeps: Attach to the bottom of exterior doors to block drafts and prevent dust and pests from entering.
Before applying weatherstripping, be sure to clean the area thoroughly to help the material adhere properly.
3. Use Caulk for Stationary Gaps
If you notice cracks around stationary parts of your doors or windows—such as the frame or siding—caulking is your go-to solution. Use exterior-grade, paintable silicone or acrylic latex caulk for durability and flexibility.
To apply:
- Remove any old, crumbling caulk.
- Clean the surface.
- Apply a steady bead of caulk along the crack.
- Smooth it with a caulk tool or your finger dipped in soapy water.
This helps protect your home from water infiltration and stops unwanted airflow.
4. Upgrade to Energy-Efficient Glass
If your home has older, single-pane windows, consider upgrading to double- or triple-pane glass. These types of windows offer better insulation by trapping air (or gas) between layers of glass.
Energy-efficient glass can drastically reduce heating and cooling loss, saving money over time. At Tashman, we offer a wide selection of custom glass solutions that meet or exceed California’s strict energy efficiency codes.
5. Install Storm Doors or Windows
Installing storm doors or windows adds another layer of insulation and protection against the elements. They can:
- Improve energy efficiency
- Block drafts and precipitation
- Add a layer of security
- Increase your home’s curb appeal
Storm doors are especially beneficial during cold winters and windy seasons, while storm windows can improve insulation without replacing existing ones.
6. Use Thermal Curtains and Window Film
Looking for a fast, affordable way to reduce heat transfer through windows? Try thermal curtains or insulating window film.
- Thermal curtains have a built-in lining that traps heat during winter and blocks solar radiation during summer.
- Window film acts as an extra barrier and often includes UV-blocking properties to protect your furniture and flooring from fading.
These solutions are ideal for renters or anyone needing a non-permanent fix.
7. Insulate Around Frames
In older homes especially, poor insulation around window and door frames is a common issue. If you’re sealing larger gaps:
- Use spray foam insulation for tight spots that are hard to reach with traditional insulation.
- Insert backer rods (foam rods) into wide cracks before caulking to help fill the space.
Proper insulation around frames is key to creating a weather-tight seal that lasts.
Seasonal Tips for Maintenance
Weatherproofing is most effective when paired with seasonal maintenance. In the fall and winter, it’s important to reapply caulk before rain and colder temperatures set in. Take the time to inspect and replace any worn weatherstripping to maintain an airtight seal. Also, keep an eye out for water stains around your windows, which may be a sign of leaks that need immediate attention.
During the spring and summer, clean and inspect all seals after heavy rain or intense heat to ensure they haven’t degraded. Switch to light-colored window treatments, which help reflect sunlight and keep your interiors cooler. You can also use natural ventilation to your advantage by strategically opening windows during cooler parts of the day or in the evenings.
Common Mistakes to Avoid
Even the best materials can fall short if not installed or maintained correctly. One common mistake is using indoor caulk on outdoor surfaces—it simply won’t hold up to the elements and will deteriorate quickly. Another frequent oversight is skipping surface preparation; sealing works best when surfaces are clean and dry. Additionally, many homeowners forget to measure gaps accurately before purchasing weatherstripping, which can lead to poor sealing performance. Finally, don’t ignore thresholds and door sills—these areas are often overlooked but play a crucial role in preventing drafts and moisture intrusion.
