Pre-Hung Doors vs Slab Doors: Which Costs More?
Many homeowners ask whether they should buy a slab door or a pre-hung door.
Slab Doors
- Lower purchase price
- Uses your existing frame
- Ideal if the jamb is in excellent condition
- Requires more installation precision
Pre-Hung Doors
- Includes the door, frame, hinges and jamb
- Much easier for installers
- Perfect for renovations and new construction
- Provides better alignment and smoother operation
Although pre-hung interior doors cost more initially, they often reduce installation time and produce a better finished result.

What Affects Interior Door Replacement Costs?
1. Door Material
Solid core doors cost more than hollow core doors because they offer improved durability, sound reduction, and a more premium feel.
2. Door Style
Modern shaker doors, flush doors, French doors, and decorative panel doors all vary in price depending on design complexity.
3. Door Height
Standard 80-inch doors are generally the most affordable. Taller 84", 90", and 96" doors require more material and therefore cost more.
4. Hardware
Premium handles, privacy locks, soft-close hinges, and specialty hardware increase the overall project cost.
5. Installation Complexity
Homes with uneven walls, damaged frames, or older construction may require additional adjustments during installation.
Is It Worth Replacing All Interior Doors?
If your doors are outdated, mismatched, or damaged, replacing all interior doors at the same time creates a consistent modern appearance throughout your home.
Many GTA homeowners replace every door during renovations because installers can complete multiple doors more efficiently, reducing labour costs per unit.
Why Solid Core Doors Are Worth the Investment
Although solid core interior doors cost more than hollow core doors, they provide several long-term benefits:
- Excellent sound insulation
- Heavier premium feel
- Better durability
- Higher perceived home value
- Improved privacy for bedrooms and offices
Solid core shaker doors have become one of the most popular upgrades for homes across Toronto and the GTA.
