Steps to Stop Cold Air
- Weatherstrip Check: Inspect the rubber seals along all edges for cracks, gaps, or compression marks that let cold air pass through
- Track Cleaning: Dirt and debris in the bottom track prevent the door from closing flush, creating gaps that invite drafts inside
- Roller Adjustment: Rollers wear down over time and can tilt the door panel, breaking the seal between the frame and glass
- Film Application: Temporary window film adds a layer of thermal protection for Bellingham’s coldest months without permanent changes
- Full Replacement Option: When repairs can’t solve ongoing draft problems, a new Soft-Lite Sliding Patio Door offers a winter proof sliding glass door solution
- Professional Seal Test: Our crews test air leakage at every seam to confirm your door meets performance standards before we finish
Top Recommendation: Full replacement with a Soft-Lite Sliding Patio Door for long-term comfort and performance.
Best for Budget: New weatherstripping and track cleaning can resolve minor draft issues at low cost.
Best for Harsh Winters: ProVia’s Q-Lon Weatherstripping interlocks at corners for a complete thermal barrier.
