Everything You Need to Know About Garage Door Weather Stripping

Your garage door does more than open and close. It shields your home from the elements, protects stored items, and can even influence your utility bills. A well-sealed garage door makes a noticeable difference in both comfort and efficiency, especially during Northeast Wisconsin winters and humid summers.

Weather stripping, typically made of rubber or vinyl, lines the top, sides, and bottom edges of the door or frame. When installed correctly, it creates a protective barrier that keeps out drafts, moisture, and pests while helping your garage stay secure.

Benefits of weather stripping include:

• More consistent indoor temperatures and lower utility costs

• Protection against rain, ice, and standing water

• Reduced wear on your door and garage floor

• A barrier against insects, rodents, and debris

The 6 Types of Garage Door Weather Stripping

1. Bottom Seals (Door Sweeps): Long rubber or vinyl strips compress against the floor when the door is closed. Available in P-shaped, T-shaped, bulb, or J-shaped designs, they block gaps, moisture, and pests.

2. Threshold Seals: Attached to the garage floor instead of the door, these seals help stop water from running inside, especially on sloped driveways or uneven floors.

3. Top and Side Seals: Flexible strips mounted to the door stop molding along the frame, creating a tight seal at the top and sides of the door.

4. Brush Seals: Made from dense bristles, brush seals are excellent for filling irregular gaps and blocking dust and insects.

5. Stops with Integrated Weather Stripping: These combine wood-look molding with a built-in flexible seal, often used when replacing older stops that no longer provide a good seal.

6. Panel Weather Stripping: V-shaped rubber strips designed for older wooden doors with flat-edged panels. They seal the gaps between sections when the door is closed.

Why Maintenance Matters

Weather stripping does not last forever. Rubber and vinyl can become brittle, crack, or even fall out with age and exposure. Regular checks help prevent wasted energy and water damage.

Examine your weather stripping twice a year, ideally in late fall and early spring. Look for:

• Cracking, flaking, or missing sections

• Light coming through around the edges

• Drafts, puddles, or signs of pests

• Rust on retainers or hardware

If you spot any of these, it is time for replacement.

How to Install Garage Door Weather Stripping

The installation process depends on the type of product:

• Bottom Seals: Slide U-shaped gaskets into the channel on metal doors or nail strip-style seals to wooden doors.

• Threshold Seals: Use the adhesive included with most kits or secure with screws for added strength.

• Stops and Side Seals: Cut to size and fasten tightly to the frame with screws or nails so the flange compresses slightly against the closed door.

• Brush Seals: Slide into a retainer mounted to the frame and trim as needed.

• Panel Seals: Peel-and-stick strips attach directly to panel edges for a fast, effective seal.

Quality products generally last two to three years, but doors exposed to extreme weather may need attention sooner. Always replace entire sections to maintain an even, consistent seal.

Final Tips for a Well-Sealed Garage

• Use weather stripping made from durable materials designed for your climate.

• Measure carefully to ensure a tight fit without excess gaps.

• Clean the area before installation for better adhesion and longer lifespan.

• If you are not comfortable replacing seals yourself, call a professional to ensure a safe, precise installation.
