Door To Window or Window To Door Conversions: Pros and Cons
Home renovations often bring tough choices. One common question Toronto homeowners face is: Should I replace a door with a window or a window with a door? The decision impacts not only the functionality of your home but also natural light, indoor-outdoor flow, and overall property value.
Both conversions can be beneficial when planned correctly, but each comes with its own set of structural, permitting, and cost considerations. This guide will help homeowners understand the pros and cons of each option and provide insight into when each makes sense.
What Are The Differences Among Them
Before making a choice, it’s important to understand the difference between the two types of conversions:
Window-to-door: Transforming an existing window opening into a full-size exterior door. It is often to improve access to a patio, backyard, or basement.
Door-to-window: Replacing an existing exterior door with a window. It is typically to create more wall space, improve light, or enhance energy efficiency.
Both projects involve more than just swapping units; they affect the structure, function, and appearance of your home. Professional assessment is crucial for ensuring safety, compliance with Toronto building codes, and achieving a seamless outcome.
When Replacing a Window With a Door Makes Sense
Converting a window into a door is ideal when you want to improve access and functionality. It can add backyard or patio access and create a better indoor-outdoor flow.
It is also useful for creating a walk-out basement or a convenient side entrance. This conversion can also brighten your home by letting in more natural light and boosting its overall value.
Benefits:
Improves accessibility and flow
Adds functionality to living spaces
Enhances curb appeal and resale value
Considerations:
Requires structural adjustments and possibly reinforcing the wall
Permits are required under Toronto building regulations
Costs can be higher than a standard window replacement
When Replacing a Door With a Window Makes Sense
Replacing a door with a window is a smart choice when you want to maximize interior space and improve light. It can increase usable wall space for furniture or storage, add more natural light to brighten the room, and enhance privacy or energy efficiency.
Benefits:
Frees up interior space
Enhances aesthetics and light
Can improve insulation and reduce energy costs
Considerations:
You lose an entry point, which may affect accessibility
Structural work may be needed to support the new opening
A building permit is typically required in Toronto
Pros and Cons Comparison
Conversion Type | Pros | Cons |
|---|---|---|
Window-to-Door | Adds access, improves flow, boosts home value | Higher cost, structural work needed, permits required |
Door-to-Window | Frees wall space, adds light, improves energy efficiency | Lose an entry point, may require framing changes, permit needed |
Structural & Code Considerations
Both window-to-door and door-to-window conversions affect your home’s structure. It’s essential to identify whether the wall is load-bearing or non-load-bearing and to install the correct headers and framing to maintain structural safety.
In Toronto, as well as under the Ontario Building Code, permits are required for any openings that alter the structure or function of a wall. Additionally, proper sealing and insulation are essential to prevent water leaks and reduce energy loss.
Cost Considerations
Window replacement cost or any replacement depend on the project complexity, materials, and finishes. That also true here:
Structural changes and framing
Permits and inspections
Door or window type and material
Finishing work (drywall, trim, siding, steps)
Any electrical or plumbing adjustments
In Toronto, typical conversions cost between $3,500 and $8,000, depending on project complexity. Hiring a professional ensures your investment is safe, code-compliant, and durable.
