When to Hire a Window Installer

Consider window replacement when existing windows are drafty, foggy between panes (seal failure), difficult to operate, or visibly deteriorated. Windows over 20 years old often justify replacement for energy savings. Single-pane windows in particular benefit from upgrading to double or triple-pane units.

Questions to Ask Before Hiring

• Do you offer both insert and full-frame replacement options?
• What is the U-factor and SHGC rating of windows you recommend?
• Are your windows ENERGY STAR certified for our climate zone?
• How do you handle interior and exterior trim?
• Do you offer any financing options?
• What warranty is provided by the manufacturer vs. your company?
• Can I get a written quote without same-day signing pressure?

Red Flags to Watch For

• High-pressure sales tactics or "today only" pricing
• Won't provide written quote without commitment
• Claims of 40-50% energy savings (usually exaggerated)
• Only offers one brand or product line
• Doesn't discuss installation method (insert vs. full-frame)
• Won't explain window ratings and what they mean
• Dramatically higher or lower than competitors

Cost Considerations in St. Louis

Replacement windows in St. Louis cost $400-$1,200+ per window installed, depending on size, style, and quality. Vinyl windows are least expensive; fiberglass and wood cost more but offer better performance. Full-frame replacement (removing entire frame) costs 30-50% more than insert replacement but may be necessary for rotted frames. Get at least 3 quotes and compare specifications, not just price.
