Weatherstripping Replacement

What Weatherstripping Does

Weatherstripping creates the seal between the moving parts of your window—the sash—and the fixed frame. It blocks air infiltration when the window is closed. Over time, weatherstripping compresses, cracks, tears, or simply wears away, allowing air (and sometimes water) to pass through.

Signs Your Weatherstripping Needs Replacement

• Drafts near windows, especially noticeable on windy days
• Visible daylight around the window sash
• Dust accumulation near windows
• Increased heating/cooling bills
• Visible damage—cracks, tears, compression, or missing sections
• Window rattles in the wind

Types of Weatherstripping

Compression weatherstripping is used on casement and awning windows. It compresses when the window closes, creating a tight seal.

Fin seal weatherstripping uses flexible fins to seal sliding windows and double-hung sashes against the frame.

Bulb seal weatherstripping has a tubular profile that compresses against the frame on various window types.

Foam weatherstripping is an economical option for some applications but doesn't last as long as other types.

Our Weatherstripping Service

We assess your windows, identify the correct weatherstripping type (there are many profiles and sizes), and install new material for a proper seal. For older or unusual windows, we can often find or fabricate compatible weatherstripping.

Results You'll Notice

After weatherstripping replacement, you should notice: less draft near windows, more consistent indoor temperatures, quieter operation, reduced dust infiltration, and potentially lower energy bills.
