Windows and glass features are more than just functional elements in your home—they define your view, bring in natural light, and enhance the overall aesthetic of your property. But like all home components, windows and glass can develop problems over time. From minor scratches to serious cracks, these issues affect safety, energy efficiency, and curb appeal.
Most homeowners increasingly rely on professional glass and window repair in Markham to maintain their property’s value and ensure safe, reliable operation.
1. Cracked or Broken Glass
Cracks or shattered glass are one of the most obvious and potentially dangerous window problems. Cracks can occur due to:
- Accidental impacts from objects or pets
- Extreme temperature changes causing glass expansion and contraction
- Structural shifts in the building
Even small cracks compromise the safety of the glass. A tempered window may seem sturdy but can shatter completely if pressure continues.
How to fix it:
- Small chips may be repaired with professional glass fillers or resin techniques
- Larger cracks or shattered panes usually require full glass replacement
- Always hire a certified technician to handle tempered or laminated glass safely
Regular inspection and immediate attention to cracks prevent escalation into more dangerous situations.
2. Foggy or Condensed Windows
If you notice condensation or fog between the panes of double- or triple-glazed windows, this indicates that the seal is failing. Moisture entering the space reduces energy efficiency and can cause mold growth, leading to unhealthy indoor conditions.
Causes:
- Aging or worn-out seals
- Manufacturing defects
- Extreme temperature fluctuations
How to fix it:
- Replace the window’s insulating glass unit (IGU)
- Re-seal or re-glaze to restore airtightness
- Consider upgraded double or triple glazing for energy efficiency
Addressing foggy windows quickly can restore clarity, improve insulation, and reduce energy costs.
3. Sticking or Difficult-to-Operate Windows
Windows that are hard to open or close are more than an inconvenience—they can be a safety hazard and compromise ventilation.
Common causes:
- Swelling due to humidity or water damage
- Misaligned frames or sashes
- Dirt, paint, or debris blocking tracks
How to fix it:
- Clean and lubricate the window tracks
- Adjust or realign the frame
- Replace worn hardware or weatherstripping
Regular maintenance prevents windows from sticking and prolongs the life of both the frame and glass.
4. Drafts and Air Leaks
Drafty windows reduce energy efficiency, increase heating and cooling bills, and make indoor spaces uncomfortable. Air leaks often occur when:
- Weatherstripping is worn or missing
- Frames have warped over time
- Seals around glass panes fail
How to fix it:
- Replace worn weatherstripping
- Re-seal frames with high-quality caulking
- Upgrade to energy-efficient windows with insulated glass
Professional inspection can identify hidden leaks and ensure a complete, long-lasting fix.
5. Broken or Faulty Window Hardware
Handles, locks, latches, and hinges are essential for proper window function. Malfunctioning hardware can:
- Prevent the window from opening or closing
- Compromise security
- Cause stress on glass, leading to cracks or chips
How to fix it:
- Replace damaged handles, locks, or hinges
- Adjust alignment to ensure smooth operation
- Use high-quality, durable hardware to prevent future issues
Proper hardware maintenance ensures safety, ease of use, and prevents unnecessary strain on glass panes.
6. Scratched or Etched Glass
Over time, glass surfaces can become scratched, etched, or dulled. Common causes include:
- Cleaning with abrasive materials or chemicals
- Accidental contact with sharp objects
- Hard water deposits and mineral buildup
Scratches not only affect appearance but can also weaken glass over time.
How to fix it:
- Minor scratches can be polished using professional glass restoration kits
- Deep scratches may require panel replacement
- Protective coatings or tempered glass upgrades can prevent future damage
Maintaining the aesthetic quality of glass ensures your home looks modern and well cared for.
7. Condensation Between Glass Layers
While similar to foggy windows, condensation between panes specifically signals that the insulating seal has failed. This type of issue often occurs in double-pane windows and can lead to energy inefficiency and mold development.
Causes:
- Broken seals around insulated units
- Improper installation
- Age-related wear and tear
How to fix it:
- Replace the insulated glass unit entirely
- Ensure professional reinstallation to prevent recurring problems
- Upgrade to better energy-efficient glazing options
Routine inspections allow homeowners to catch this problem early, avoiding moisture damage and high replacement costs.
