When a window cracks, fogs up, or simply stops keeping the weather out, the question isn’t whether to fix it — it’s how fast you can get it done right. At Tualatin Valley Glass, we’ve been handling window glass replacement across Portland, Tigard, Beaverton, and the surrounding metro area since 1975. Here’s what you need to know before scheduling a replacement.
When Does Window Glass Need Replacement?
Not every chip or crack means a full replacement. But certain signs tell you the glass itself has failed:
- Foggy or cloudy glass between panes — The insulated glass unit (IGU) seal has broken. Moisture is trapped between the panes, and no amount of cleaning will fix it.
- Cracks that span more than 6 inches — Small chips can sometimes be stabilized, but longer cracks compromise structural integrity and will spread with temperature changes.
- Drafts around the window — Cold air coming through a closed window means the glass may have shifted or the seal has failed.
- Visible moisture damage on the frame — Water intrusion from failed glass can rot wood frames. Replacing the glass early prevents expensive frame repairs.
- Single-pane glass in a heated space — Upgrading from single-pane to dual-pane Low-E glass can cut heat loss by 50% or more.
Types of Replacement Glass We Install
The right glass depends on where the window is and what it needs to do:
- Insulated Glass Units (IGUs) — Dual-pane or triple-pane units with argon gas fill. Most common for residential window glass replacement in Portland.
- Low-E Coated Glass — Cardinal, Solarban, and Guardian coatings that reflect heat while letting light through. Essential for Oregon’s mixed climate.
- Tempered Safety Glass — Required by code near doors, in bathrooms, and near stairs. Breaks into small pieces instead of jagged shards.
- Laminated Glass — Holds together when broken for security and sound reduction. Popular for ground-floor windows.
- Obscure and Pattern Glass — For bathrooms and privacy. Available in rain, chinchilla, and other patterns.
How Window Glass Replacement Works
Most replacements don’t require replacing the entire frame:
- Measurement — Exact opening, glass type, and frame condition check. For IGUs, we note airspace and coatings.
- Glass fabrication — Custom-cut to your dimensions. IGUs built with spacer bars, desiccant, and sealant. 5-7 business day turnaround.
- Installation — Remove failed glass, clean frame, set new glass with proper shimming, seal everything. 30-60 minutes for most windows.
- Cleanup — Old glass hauled away, window cleaned, operation verified. Workmanship guarantee included.
