How much does it cost to upgrade the weatherstripping on all my garage windows and service door in Ottawa?

Upgrading weatherstripping on garage windows and the service door typically costs $150 to $400 for materials and labor in Ottawa, depending on the number of windows, door size, and type of weatherstripping you choose. Most garage door companies and handyman services charge $200 to $350 for a complete weatherstripping replacement job that includes the service door and 2-4 windows.

This upgrade becomes particularly valuable in Ottawa's extreme climate where temperature swings from -30°C to +35°C put enormous stress on weatherstripping materials. Old, cracked, or compressed weatherstripping allows cold air infiltration that can freeze water lines, make the garage uncomfortable for workshop use, and dramatically increase heating costs if your garage is heated. The freeze-thaw cycles we experience 50+ times per winter cause rubber and foam weatherstripping to lose elasticity and create gaps that worsen each season.

For materials, you'll spend $40 to $80 on quality weatherstripping for a typical two-car garage. EPDM rubber weatherstripping ($8-12 per linear foot) performs best in Ottawa's temperature extremes and resists cracking better than cheaper foam alternatives. The service door typically needs weatherstripping around the frame plus a door sweep or threshold seal at the bottom. Windows need weatherstripping around the sash where they meet the frame. Professional installation ensures proper compression and alignment, which is crucial for effectiveness.

Important considerations: Inspect the door and window frames themselves while upgrading weatherstripping. If frames are warped or damaged, new weatherstripping won't seal properly. Also check that windows and doors close tightly against the new weatherstripping - you may need minor adjustments to latches or hinges. Replace weatherstripping every 3-5 years in Ottawa's harsh climate, or sooner if you notice drafts, ice buildup, or visible cracking.

This is an excellent DIY project for most homeowners with basic tools and a few hours of time, making it one of the most cost-effective garage comfort improvements you can make.
