Glass Repair vs Window Glass Replacement – When to Repair and When to Replace

Choosing between replacing just the glass (pane or IGU) and full window glass replacement depends on the size, location, and severity of the damage. We do not fill or seal cracks; we replace the glass. In many cases, replacing only the damaged glass is the better option - it is faster, far less expensive (around $200 vs roughly $2,000 for full window glass replacement), and preserves your existing frame and trim. OhMyGlass provides a free on-site assessment across the GTA so you only pay for what you actually need. Our technicians evaluate every job individually and recommend glass-only replacement when it will provide a lasting result, and full window replacement only when safety or structural integrity requires it.

When Replacing Just the Glass Is the Better Option

Replacing only the damaged glass (the pane or insulated glass unit) saves money and time when the frame is still good. We do not fill or seal cracks; we replace the glass. Our technicians recommend glass-only replacement when the following conditions apply.

• A single pane or one section of glass is damaged (cracked, chipped, or shattered) and the rest of the window and frame are sound - we replace that glass only.
• Foggy or steamy double-pane windows where the seal has failed - we replace only the insulated glass unit (IGU), not the whole frame, for a fraction of the cost of a full window.
• Damage is limited to one pane or one IGU so that replacing just that unit restores the window without replacing the entire window.

When Window Glass Replacement Is Necessary

Full window glass replacement is the right choice when replacing just the pane or IGU would be unsafe, short-lived, or not cost-effective compared to installing a new window.

• Cracks longer than about six inches, or chips larger than a quarter, especially in critical viewing areas or near the edge of the glass.
• Damage that has penetrated through both layers of a double-pane unit or deep into the pane, compromising the structural strength of the glass.
• Multiple chips or cracks in one pane - we replace that pane or the full IGU; we do not patch or fill cracks.
• Shattered tempered glass - once tempered glass breaks, the entire pane disintegrates and must be replaced.
• Frames or seals that are warped, rotted, or have failed repeatedly - replacement provides better long-term value and safety in these situations.

Cost Comparison: Glass Repair vs Window Glass Replacement

Replacing just the glass—a single pane or the insulated glass unit (IGU) while keeping your frame—typically runs around $200 or so depending on size and glass type. We replace the glass; we do not fill or seal cracks. Full window glass replacement (new glass and often frame work) is usually in the $2,000 range per window depending on size, type, and accessibility. OhMyGlass focuses on glass-only replacement when the frame is still good, so you only pay for what you need. We provide a written quote before any work begins so you know your costs upfront.

Why Get a Professional Assessment?

The decision to replace just the glass (pane or IGU) or opt for full window glass replacement depends on several factors that are difficult to evaluate without hands-on inspection: extent of damage, condition of the frame and seals, and whether a single pane or the whole window is affected. We do not fill cracks; we replace the glass. A professional assessment avoids unnecessary full window replacement when glass-only replacement will do (saving you roughly $200 vs $2k), and ensures full replacement is chosen when safety or durability requires it.

Frequently Asked Questions

Do you fill or seal cracks? No. We replace the glass—either the damaged pane or the whole insulated glass unit (IGU)—while keeping your frame when it is still in good condition. That glass-only replacement (around $200) is far less expensive than full window glass replacement (around $2,000). Does insurance cover broken window glass? Many home insurance policies cover accidental glass breakage, though deductibles vary. We can provide a detailed invoice for your insurance claim. How long does a glass repair take? Most single-window glass replacements are completed in 30 to 60 minutes on-site. IGU replacements may take slightly longer if the sealed unit needs to be fabricated to custom dimensions.
