Double- and triple-pane windows have seals that separate the glass layers and trap insulating gas. When these seals fail, moisture enters the gap, causing the persistent fog or condensation you see between panes. This is extremely common in Vancouver due to humidity and temperature fluctuations.
Repairing foggy glass depends on the window type and seal condition. In many cases, the entire sash (moving part) or even the whole window frame must be replaced because the seal cannot be restored from outside. However, some windows can have just the glass pane replaced if the frame is still sound, costing CA$400–CA$800 per window. Full window replacement typically runs CA$1,200–CA$2,500 per unit installed.
If your windows are less than 10 years old and under warranty, contact the manufacturer—many cover seal failure.
Stuck Sashes and Binding Windows
Stuck or difficult-to-open windows are usually caused by paint buildup, dirt accumulation, swollen wood frames from moisture, or corroded hardware. Vancouver's humid climate accelerates wood swelling and paint degradation, making this a frequent issue in older homes.
Repair typically involves cleaning tracks, lubricating hinges and pulleys, and carefully breaking paint seals—a process that costs CA$100–CA$300 per window. In some cases, sash cords or springs need replacement (CA$150–CA$400). This repair approach preserves original character, which many Vancouver homeowners value, especially in heritage properties.
If the frame wood is soft or crumbling when probed, structural damage has occurred and replacement becomes necessary.
Frame Rot and Water Damage
Frame rot is a serious concern in Vancouver's rainy climate. Water penetration around window frames causes wood to deteriorate, leading to soft spots, discoloration, and structural weakness. This problem spreads quickly and can affect surrounding wall framing if left untreated.
Small surface rot (less than 2 inches in area) can sometimes be cut out, treated, and filled with epoxy or wood filler for CA$200–CA$500 per window. However, extensive rot—affecting more than 25% of the frame—typically requires full window replacement to prevent further water damage and maintain thermal performance.
Repairs to rotted frames should include waterproofing the exterior and addressing the source of moisture. If your home has experienced water leaks or you live in a high-moisture area, professional inspection is recommended before attempting repairs.
Hardware Damage and Missing Components
Window hardware includes locks, latches, handles, balance springs, hinges, and weather stripping. Damaged or corroded hardware compromises security, weatherproofing, and ease of operation. Vancouver's salty air near the coast accelerates hardware corrosion.
Many hardware issues can be repaired affordably: replacing a broken handle costs CA$30–CA$100, installing new weather stripping runs CA$50–CA$150 per window, and repairing balance springs or latches typically ranges CA$75–CA$250. These repairs often restore full functionality and improve energy efficiency.
If hardware damage is combined with frame or seal issues, however, replacement may be more cost-effective than piecemeal repairs.
Repair vs. Replacement: The Decision Framework
Deciding whether to repair or replace depends on several factors: window age, material condition, energy efficiency, deductible coverage (if claiming under insurance), and your long-term plans.
Repair is typically worth pursuing if: the window is less than 15 years old, only one component is damaged, the frame is solid and dry, and repair costs are less than 50% of replacement. For a single foggy window or stuck sash in Vancouver, repair often saves CA$800–CA$1,500 per unit.
Replacement becomes the smarter choice if: multiple windows have failed seals, frame rot is widespread, the home is older than 25 years (upgrades to modern energy-efficient models reduce heating costs by 10–15%), or several problems exist simultaneously. Most Vancouver homeowners benefit from replacing 3+ problem windows at once to reduce labor costs and achieve consistent thermal performance.
If you're covering costs through insurance, check your deductible before deciding—repairs sometimes cost less than your deductible, making them your out-of-pocket responsibility anyway.

Frequently Asked Questions
How long do window repairs typically take in Vancouver?
Simple repairs like hardware replacement or cleaning stuck sashes usually take 1–2 hours per window. More complex repairs, such as sash cord replacement or small frame rot treatment, may take 3–4 hours. Seal failures requiring glass or sash replacement can take a full day depending on the number of windows. Weather and frame accessibility may extend timelines.
Can fogged windows be repaired, or do they always need replacement?
Fogged windows cannot be truly repaired because the broken seal cannot be resealed from outside. However, you have options: replace just the glass pane if the frame is good (CA$400–CA$800), replace the sash assembly, or replace the entire window. The best choice depends on your window's age, frame condition, and budget. Many manufacturers offer lifetime seal warranties—check before paying for repairs.
Is window repair covered by insurance in Vancouver?
Window damage from covered events (storms, break-ins, falling branches) may be covered under your homeowner's insurance policy, subject to your deductible. Routine wear and tear, including seal failure and wood rot from neglect, are typically not covered. Always check your specific policy and consider whether repair costs exceed your deductible—if they don't, you'll pay the full repair cost out of pocket.
Should I repair or replace my windows if they're 20+ years old?
Windows older than 20 years often have multiple issues and poor energy efficiency. If two or more windows need repairs, replacement is usually more economical in the long run. Modern energy-efficient windows reduce heating bills by 10–15%, which pays for itself over 7–10 years in Vancouver's climate. Get quotes for both repair and replacement to compare total costs.
How do I prevent window problems in Vancouver's rainy climate?
Maintain good drainage around your home's exterior, keep gutters clean, and ensure water flows away from the foundation. Caulk gaps around window frames every 5–7 years, and check weatherstripping regularly. Keep windows clean and dry, and operate them occasionally to prevent corrosion and binding. Annual inspections can catch problems early, saving repair costs.
