Twice-yearly care keeps them smooth, efficient, and durable. Contact a specialist for persistent issues.
Use mild detergent/water for frames and glass cleaner for panes. Wipe with soft cloth. Do 1–2 times yearly (more in dusty/coastal areas).
Remove dirt, sand, leaves from top/bottom tracks with brush or vacuum when fully open.
Apply silicone spray to rollers, tracks, and hardware every 6–12 months (or when stiff). Avoid oil-based products.
Inspect and clean; replace if worn or damaged.
Look for cracks/gaps in weatherstripping; replace to prevent drafts/leaks.
Ensure smooth sliding and secure locking. Adjust or call a pro if misaligned.
Clear sill drainage holes; check for leaks.
