Vinyl
The most common replacement material in our area, and for good reason. A quality vinyl frame is well insulated, never needs paint, and costs the least installed. The trade-off is that vinyl expands and contracts more than glass does across a Bemidji temperature swing, so frame quality matters more than it does in other materials. Builder-grade vinyl is where cheap replacement windows earn their bad reputation.
- Watch for: Ask about frame wall thickness and welded (not screwed) corners. Those two details separate a 30-year vinyl window from a 12-year one.
- Typical service life here: 20–30 years
- What we carry in this material: Richlin, Pella 250 Series
