When considering a renovation or simply some worn out, squeaky doors, one of the first questions you’ll be asking is: How much does interior door installation cost in Toronto? The truth is that it depends – but that isn’t helpful when it comes to budgeting. This guide gives the real 2026 cost of hollow core doors, solid core doors and fully custom interior doors, as well as the hidden costs, hardware and labour that can impact the total cost.
No matter if you’re updating one bedroom door or changing all the interior ones in your Toronto home, knowing these price ranges will help you make an informed comparison and make sure you don’t end up paying more than you should.
What Affects Interior Door Installation Cost in Toronto?
When considering specific ranges, it’s useful to know what factors either raise or lower the price of any interior door project:
- Configure the door size and type – slab, French doors, double doors, barn doors, or pocket doors
- Pre-hung or slab only – pre-hung (door + frame) is more expensive, but installs faster
- State of existing frame – older Toronto houses, particularly those constructed prior to the 1980s, frequently have frames that have settled or are out-of-square and require correction
- Hardware – hinges, handles, locks, and closers come in a variety of styles, from the basic builder level up to designer options.
- Finishing – pre-primed doors require paint or stain, increasing the cost
- Labour rates –Toronto and the GTA have higher rates of labour, typically because of greater demand and costs of living as compared to smaller cities and towns in Ontario
- Number of doors – many installers will make a discount if you install multiple doors at the same time
Now, with that backdrop, let’s examine the actual cost of each of these door types when they’re installed.
Hollow Core Interior Door Installation Cost
Hollow core doors are the least expensive and are the most popular choice for closets, secondary bedrooms and low traffic areas.
Installed Cost (Toronto average): $200 – $500 per door
- Door only (slab): $80–$200
- Basic hardware (hinges, knob, or lever): $20–$60
- Labour: $150–$300 per door
Hollow core doors are lightweight doors constructed with a thin wood-veneer or laminate on both sides, surrounding a honeycomb cardboard core. They’re light and generally easy to install because most jobs can be done in less than two hours per door (assuming the frame is in good condition).
Where hollow core doors are applicable: storage rooms, rental properties, secondary bedrooms and closets where budget is more important than soundproofing. Not really suited to bathrooms (moisture may cause the veneer to warp over time) and not suited to rooms where you want noise reduction (the hollow centre does not provide much sound damping).
Solid Core Interior Door Installation Cost
For those looking to upgrade their door for increased durability, soundproofing and a more robust feel without paying the price of solid wood, solid core doors are the answer.
Typical installed cost in Toronto: $350–$800 per door
- Door only (slab): $150–$400
- Hardware (mid-grade hinges, lever set, sometimes a lock): $40–$100
- Labour: $150–$350 per door, depending on frame condition
Solid core doors use particleboard, engineered wood or composite core, making them heavy when compared to hollow core doors. More weight adds more installation time, as it is often necessary to verify and sometimes re-hinge existing frames for which there are many of the pre-war and post-war era throughout the Toronto housing market.
When solid core doors are appropriate: primary bedrooms, home offices, media rooms, and bathrooms where privacy and sound control are important. Many homeowners in Toronto also opt for solid core doors in the area between the living room and a garage or basement, as solid core doors have higher fire resistance levels than hollow core doors.
Custom Interior Door Installation Cost
Custom doors come in all different varieties: solid wood species (oak, maple, walnut), glass panel doors, barn doors, pocket doors, French doors, oversized or non-standard size, and decorative/ historic millwork doors. This is where the price is most different.
Typical installed cost in Toronto: $800–$2,500+ per door
- Slab of solid wood or specialty door: $400-$1,500
- Custom hardware (designer handles, soft close hinges, smart locks): $100-$400
- Labour: $250-$600 per door, additional if framing adjustments are required.
- Pocket door conversions: $500–$3,500 total – often this means opening the wall.
- Retail door installation: $1,200–$3,000 for the 2 doors, installed
Extra labor will be needed for framing and casing and extra work to match an odd or non-standard opening (which is often found in older Toronto homes and heritage properties) for custom doors. Glass-panel and French doors add to the cost, too, due to the extra handling and hardware.
Where custom doors are appropriate: Entryways, home offices that are design oriented, heritage home renovations, and any place you desire that your door be a design element and not simply a functional barrier. The following table shows the costs of interior door installations.
Interior Door Installation: Cost Summary Table
| Door Type | Door Cost | Labour Cost | Total Installed (Per Door) |
|---|---|---|---|
| Hollow Core | $80–$200 | $150–$300 | $200–$500 |
| Solid Core | $150–$400 | $150–$350 | $350–$800 |
| Custom / Solid Wood | $400–$1,500 | $250–$600 | $800–$2,500+ |
Additional Costs to Budget For
Even a basic interior door replacement can have a few additional pieces of extra info Toronto homeowners might not anticipate when planning their replacement budget:
- Old door removal and disposal: $50-$150 per door for non-bundled costs
- Repair work on frames and/or casings: $50-$200 per door, often in older homes (40+ years)
- Painting or staining: $50-$150 per door if the new door is not pre-finished
- Drywall or trim touch-ups: $50-$200; particularly when the new size opening is slightly different than the old size opening.
- Multi-door discounts: some Toronto installers offer a 10-20% discount for the fourth door and each subsequent door installed by them.
When asking your contractor, always make sure you question if removing, disposing and touch-up work is part of the price. Sometimes these extras are not listed on paper and can cost several hundred dollars for a whole house project.
Tips to Keep Interior Door Costs Down in Toronto
- Combine several doors in a single visit to lower labour costs per door
- Buy standard sizes (usually 30″, 32″, or 36″ wide x 80″ tall) to prevent extra milling costs
- Consider pre-finished or pre-primed doors to reduce painting expenses
- Re-use existing hardware when still fit, particularly hinges for mortises
- Obtain alternative quotes and verify the details carefully – door, hardware, labour, removal and finishing

Frequently Asked Questions: Interior Door Installation
How much does it cost to install an interior door in Toronto in 2026?
Hollow core or solid core doors cost $200 – $800 per door, materials and labor. The range of prices for custom or solid wood doors is typically from $800 to $2,500 or more depending on the size, material, and complexity of the door.
What is the difference between hollow core and solid core doors?
Hollow core doors are light and economical, with a honeycomb interior and are ideally suited for closets and where traffic is not that high. Solid core doors are doors which have a dense engineered wood core that offers higher sound resistance, strength and weight of feel, suitable for bedrooms, offices, or bathrooms.
Is it cheaper to buy a slab door or a pre-hung door?
Installed as a slab only, the door is cheaper initially but the frame must be in good shape and square. A pre-hung door (door and frame) is more expensive, but is a better option for older homes in Toronto where frames may have shifted over time, ensuring that the door fits properly.
How long does interior door installation take?
Generally, one simple, basic interior door replacement can take approximately 1-3 hours. Half day to full day will be required for custom doors, French door or pocket door conversions, depending on the requirements, such as framing or wall work.
Do I need a permit to replace an interior door in Toronto?
In general, no – interior doors that are replaced for a similar purpose and don’t alter the size of the opening or do structural work on the wall do not need a permit. When widening an opening or removing a load-bearing element, consult with your contractor as approval from the City of Toronto may be necessary.
Can I install an interior door myself to save money?
If you have an existing frame that is square and still in good condition, then it is possible to do it yourself to make a simple slab swap. When they are not properly aligned however, drafts, sticking doors and uneven gaps occur. With solid core, custom, and pocket doors, professional installation is recommended to prevent rework costs.
Does replacing interior doors add value to a Toronto home?
