Interior Door Installation Toronto & the GTA
For most people in Toronto, the front door is the first thing they consider when upgrading their home. But so do the doors within your home – how each room feels, how sound carries from room to room, how private your home office will be when you’re video calling, what amount of natural light flows through your floor plan.
Milano Windows & Doors has been installing interior doors across Toronto and the Greater Toronto Area for over 27 years. From replacing a hollow-core door that makes loud noises when closed to installing a solid-core set of interior French doors between your living and dining room to installing solid-core doors throughout your home, our team brings a clean and professional installation, no damage to walls, trim or flooring.
Installing interior doors in Toronto can range in price from $200 to $900 per door installed, depending on the type of door, what it’s made of and if the rough opening needs to be modified. No-cost, no obligation written quotes and in-home consultations available.
Types of Interior Doors We Install
Milano installs every style of interior doors in Toronto and the GTA area. We’ve described in detail what we provide and who each style is for.
Solid-Core Interior Doors
The most popular upgrade for Toronto homeowners. Solid core doors are composite or wood core, heavier, with significantly reduced sound transmission properties, with longer service life and feel heavier when closed. They may be smooth or textured finish, can be primed for painting, or even be pre-stained with various wood stains.
Hollow-Core Interior Doors
Hollow core doors are inexpensive and lightweight, and have been used in most builder homes in Toronto up to 2015. If you want to replace a broken or warped hollow core door with an exact replica, it is the cheapest option. They come in handy in spaces where sound and privacy are not needed like laundry rooms, closets, and pantries.
Interior French Doors
Double panel glass doors opening off the centre, for light flow and openness between two rooms within the house. From living rooms to dining rooms, home offices to hallways, main floors to open floor plans. To achieve privacy, interior French doors come in clear glass, frosted glass or decorative glass.
Barn Doors & Sliding Interior Doors
When a swinging door takes up too much of valuable floor space, a horizontal moving barn door which rolls along a track affixed to the wall is ideal. Barn doors are popular in Toronto renovations, especially for older homes with a small hallway and can be constructed from wood, painted MDF or glass.
Bifold Doors
Bifold doors fold in on each other and are primarily employed for storage rooms, washrooms and wardrobes. They are able to give a complete opening without taking up floor space for the swinging arc. It comes in various finishes including louvred, solid, and glass panel to accommodate different interior design styles.
Pocket Doors
Pocket doors open into a recess in the wall so they completely hide when opened. The perfect space-saving interior door solution, perfect for en-suite bathrooms, walk-in closets, and between kitchen and dining spaces. A pocket door will necessitate cavity work in the wall – we will determine feasibility at the free consultation.
Why Interior Doors Matter More Than You Think
Interior doors are opened and closed hundreds of times a year. If a door sticks, squeaks, hangs crooked, or it just looks dated, the way you use your home will change every day. In addition to their role in providing access, interior doors have a direct influence on:
Sound Privacy
A solid core interior door will typically provide up to 50-70% reduction in sound transmission between rooms, compared to a hollow core door. It's a big deal factor for home offices, bedrooms and media rooms in the growing work from home Toronto households.
Light Flow
Without sacrificing interior space, you can let natural light in through your house with the use of interior glass doors – French doors, barn doors with glass inserts, or doors with transom panels.
Energy Efficiency
Properly fitted interior doors can also help control the air exchanges between the heated and unheated parts of the house, which will give a more balanced internal temperature.
Home Value
Toronto real estate agents discuss this consistently, as some of the top things on a buyer's radar when viewing a home are interior doors, hardware and trim. Modern hardware combined with solid-core doors conveys a sense of quality that hollow-core doors cannot rival.
Interior Door Materials: What to Choose
Solid Wood
Real wood interior doors add warmth, authenticity and good sound dampening. Highly stainable and can be painted to fit any interior color scheme. The high-grade option: Solid wood – more durable, heavier, and more costly than composite options. Perfect for heritage homes, traditional interiors, and homeowners seeking the real deal.
MDF (Medium Density Fibreboard)
MDF interior doors are the most popular option in Toronto renovations. They are also very dimensionally stable – not expanding, contracting, or warping like solid wood would in varying humidity like it does – and they accept paint exceptionally well, giving a smooth, uniform finish. MDF doors are low maintenance, affordable, and best fitted for modern interiors.
Hollow Core Composite
Standard in most new developments in the GTA. For projects that require low-volume spaces and have a lower budget, they are more appropriate and work best for projects that don't have to perform well.
Interior Door Hardware & Finishing
As with anything else, a door is only as good as its complement. From matte black to brushed nickel, satin brass, chrome to oil-rubbed bronze, Milano offers interior door hardware in a variety of finishes to match both modern and classic styles. We handle:
- Work with sets and lever hardware
- Privacy locks for bathrooms and bedrooms.
- Hinges – standard or concealed.
- Door stops and magnetic catches
- Soft-close mechanisms for barn doors andentry
You can also have your new door primed and painted for an extra fee, so it comes ready-to-hang without having to be primed and painted first.

Interior Door Installation Cost in Toronto
Interior door installation costs in Toronto are generally between $200 to $900 per door installed, but the average installation price is $350 to $600 per door in an existing opening with hardware in place.
Key factors that influence your final cost:
Door Type
Each of these – solid-core, barn, pocket, or French – has a different cost for the material. Solid wood and pocket doors are at the top end, while hollow-core costs the least.
Opening Condition
If the rough opening is the proper size and the frame is in good condition, it will be easy to install. Additional labour is required if the opening must be modified, framed or re-trimmed.
Hardware Selection
Our typical quotes include standard hardware. Enhanced finishes, privacy locks and soft-close features are optional.
Number of Doors
Multi-door projects – where 5+ interior doors are replaced in a single trip – often are cheaper per door because setup and travel costs are not distributed among the doors themselves.
To get the most accurate number, you’re best to schedule a free in-home appointment. Each opening is measured, options are discussed, and there are no surprises – it’s all in the written quote.

Frequently Asked Questions – Interior Door Installation Toronto
What is the difference between a solid-core and hollow-core interior door?
Solid core doors have a heavy composite or wood fill in the door body, which makes them more well-built, soundproof and dense. A hollow core door has a light weight cardboard honeycomb core, which is lighter and less expensive, but less effective at blocking sound. Solid-core is the best option for homeowners to upgrade for bedrooms, home offices, and bathrooms in Toronto.
Do I need a permit to install interior doors in Toronto?
No, there is no building permit needed for interior doors in Toronto, unless you’re making structural changes to load bearing walls. If a door is already in place in an opening, or a barn door is already installed in a wall, then no permit is needed for replacing the existing interior door/barn door.
How long does interior door installation take?
Interior door installation does not normally require condo board approval and does not involve altering exterior walls, common elements or building systems. Inside doors are installed in condos throughout Toronto, North York, Scarborough, Etobicoke and the surrounding GTA.
Can you install interior doors in condos and townhouses in Toronto?
Yes. Interior door installation is entirely within a unit owner’s scope and does not typically require condo board approval, as it involves no changes to exterior walls, common elements, or building systems. We install interior doors in condos across Toronto, North York, Scarborough, Etobicoke, and the wider GTA.
What interior door style is best for small rooms or narrow hallways?
Barn doors and pocket doors are the best choices in small areas. They don’t need the room for a swinging arc, freeing up much of the square footage available in narrow Toronto hallways and small en-suites. The best choice is pocket doors which are the least visible when open.
Can you replace just the door slab without changing the frame?
Yes, in many cases. When the existing door frame is structurally sound and the rough opening is of the correct size, the door slab and hardware can be replaced. We evaluate this in the free consultation and will recommend the most economical solution depending on your particular circumstances.
