Why do corner windows cost three times as much as regular ones?
why do corner windows cost three times as much as regular ones?
Corner windows don't typically cost three times as much as regular windows - that pricing seems unusually high and may indicate you're looking at a premium specialty product or getting quotes that include extensive structural work.
Legitimate reasons corner windows cost more include the need for custom manufacturing since they're not standard sizes, specialized framing requirements, and more complex installation. The corner location often requires additional structural support, especially if you're combining two windows at a 90-degree angle or installing a single wraparound unit. Weather sealing is also more challenging at corners, requiring extra attention to prevent air and water infiltration.
In the Ottawa market, corner windows typically run 50-100% more than standard windows - so if a regular window costs $600 installed, a corner window might be $900-$1,200. If you're seeing quotes three times higher, you might be looking at premium architectural units, structural modifications, or quotes that include significant framing work.
The complexity depends on your specific situation. Are you replacing existing corner windows in the same opening, or creating a new corner window configuration? New openings require structural engineering, permits, and potentially moving load-bearing elements - that's where costs can escalate quickly. Simple replacement in existing openings should be much more reasonable.
Get multiple quotes and ask for breakdowns showing window cost versus installation/structural work. This will help you understand if you're paying for premium materials, complex installation, or necessary structural modifications. For a realistic assessment of your corner window project, request a quote through Ottawa Window Pros and an installer can evaluate your situation and give you transparent pricing.
