Guide to home window repair: DIY tips, professional help, costs, safety, and maintenance.
Understanding Home Window Repair
Home window repair includes services to restore function, energy efficiency, and appearance of residential windows. Repairs can involve glass replacement, hardware, seals, frames, and weatherproofing. The aim is to extend the life of windows, reduce energy loss, and protect home value.
Common Window Problems
- Leaking or drafty windows from worn seals
- Stuck sashes or difficult operation
- Cracked or chipped glass
- Condensation between panes in insulated units
- Rot or warping of wood frames
Windows often show signs of wear through drafts, leaks, stiff operation, fogging between glass panes, and rot in wooden frames. Common issues include worn seals on double-pane units, broken balances on sash windows, cracked or chipped glass, and failed weather stripping that lets in moisture and air.
DIY Readiness: Safety First
Before attempting repairs, assess your skill level, the window type, and safety risks. Use PPE. For older homes with lead paint or asbestos or for structural frame damage, hire a licensed professional. If you are unsure about glass type (tempered vs annealed) or structural integrity, avoid DIY.
Simple DIY Fixes You Can Try
These fixes are typically safe for most homeowners with basic tools:
- Weatherstripping replacement around sashes
- Caulking gaps around the frame to improve energy efficiency
- Lubricating sliding tracks and hinges for smoother operation
- Inspecting and reseating screens to reduce air leaks
Glass Replacement Basics
Glass replacement is delicate. For IGUs or large panes, professional handling is advised. If you replace a single pane in a basic sash and you have the right glass, steps include measuring accurately, reseating with glazing points, applying glazing compound or silicone, and sealing. If the glass is tempered or part of an IGU, hire a pro.
When to Hire a Professional
Call a professional for broken glass, rot, water intrusion behind walls, failed IGUs, or structural frame damage. A licensed contractor can inspect structural integrity, energy performance, and code compliance. A pro can offer warranties on labor and parts and ensure proper installation to prevent leaks and drafts.
Choosing a Window Repair Pro
When selecting a pro, verify license and insurance, check references, and review warranty terms. Look for experience with your window type (wood, vinyl, fiberglass) and energy-efficiency credentials. For older homes, ask about lead-paint handling and request a written estimate with labor, parts, and warranty.
Maintenance and Energy Efficiency Tips
Regular checks protect your investment:
- Inspect seals and weatherstripping twice a year and after severe weather
- Lubricate hinges, tracks, and balance systems with a silicone-based lubricant
- Clean tracks and sills to prevent buildup that can affect operation
- Replace worn weatherstripping promptly to maintain efficiency
- Consider upgrading to energy-efficient glass or low-E coatings if replacing panes
Cost Guide
| Repair Type | Typical Cost | Time to Complete | Notes |
