How AELC providers clean interior high windows
Every AELC Network Provider follows the AELC Source-Control Method: do not move the contamination; capture it or contain it. For interior high windows, that means:
- Identify. Measure glass area and heights and protect floors and furniture.
- Capture. Vacuum sills and frames.
- Clean. Clean glass with extension-pole or low-drip water-fed tools.
- Verify. Check for streaks in daylight and photograph.
Typical reach class: Standard to Extended Reach. About AELC reach classes.
How often should interior high windows be cleaned?
| Setting | Recommended frequency |
|---|---|
| Lobbies and showrooms | Every 3 to 6 months |
| Offices and churches | Every 6 to 12 months |
Grease, lint, humidity and how visible the area is can shorten these intervals. See how often high dusting should be done.
How much does interior high window cleaning cost?
Typical range: $5–$20 per pane (per pane, interior). Large atrium panes are priced per square foot.
Prices are set by each independent provider. Ranges reflect published market data and AELC time standards. See the full above-eye-level cleaning cost guide.
DIY vs. hiring a pro
