DIY vs professional window repair
Some minor issues, like weatherstripping replacement, glazing, or sealant touch-ups, can be tackled by confident homeowners. More complex problems—such as replaced double-pane units, sash reconstruction, or frame rot—usually require a certified window repair specialist. Always consider safety (ladders, glass handling) and energy efficiency when deciding.
What a pro typically handles
- Seal replacement and glazing bead work
- Replacing insulated glass units in double-pane windows
- Frame repair for rot, warping, or structural damage
- Hardware replacement (locks, hinges, balances)
- Energy efficiency upgrades such as low-emissivity coatings or weather stripping
Costs and timing
Costs vary by window type, extent of damage, and regional labor rates. Here are typical ranges to help you plan:
- DIY minor repairs (weatherstripping, sealant touch-ups): $20–$100
- Professional sealant or glazing repair: $150–$400 per opening
- Unit replacement for double-pane glass: $300–$1000 per pane
- Full frame repair or replacement (wood or composite frames): $600–$2000+
- New window installation (replacement units): $200–$1500+ per unit
Choosing a window repair professional
To ensure expertise, trust, and long-term results, follow these guidelines when selecting a contractor:
- Verify licenses and insurance, including workers' compensation where required
- Ask for references and review recent project photos
- Check warranties on both parts and labor
- Confirm energy performance ratings and, if applicable, energy-efficient upgrades
- Get written estimates with scope of work, materials, timeline, and payment terms
Maintenance tips to extend window life
- Clean tracks and hinges regularly to prevent sticking
- Lubricate moving hardware with appropriate products
- Inspect seals and weatherstripping each season and replace as needed
