This guide shares expert insights on when to DIY, when to hire a pro, how to estimate costs, and how to maintain windows for years to come, all while upholding safety and trustworthiness.
Common signs you need home window repair
- Persistent drafts or cold spots near windows

DIY vs professional window repair
DIY fixes you can safely handle
For minor issues, consider weatherstripping replacement, cleaning tracks, lubricating sashes with a silicone-based lubricant, and reinstalling hardware. Use safety gloves, eye protection, and a stable ladder. If windows are old or contain lead paint, stop and hire a pro to avoid health risks and code violations.
When to hire a professional
Cracked glass, compromised seals in double-paned units, rotted frames, or structural damage require licensed window specialists. Professional repair ensures proper glazing, alignment, and warranty coverage. Verify licenses, insurance, and manufacturer-approved parts to protect your investment.

How to choose a window repair professional
- Look for licensed/glazier-certified contractors with local references.
- Request written estimates, warranties, and a clear scope of work.

Maintenance to prevent future issues
- Regularly clean tracks and sashes to reduce friction and moisture buildup.
- Inspect weatherstripping twice a year and replace as needed.
- Lubricate moving parts with a silicone-based lubricant (avoid oil-based lubricants).
