Interior Door & Trim Renovation Toronto 2026: Big Impact, Smart Budget | David Reno

Most Toronto homeowners think about big renovation projects — kitchens, bathrooms, basements. But there’s a category of renovation that consistently delivers outsized visual impact at a fraction of the cost: interior doors and trim.

Walk through a home where builder-grade hollow-core doors have been replaced with solid-core panels, where tired 2-inch baseboards have been swapped for substantial 4-inch profiles, and where crisp new door casings frame every opening. The home feels more substantial, more finished, more thoughtfully designed — without a single wall being moved or a single fixture being replaced.

This is the “big impact, smart budget” renovation that too few Toronto homeowners explore before spending five figures on kitchen upgrades. In 2026, a complete interior door and trim refresh for a standard Toronto home typically costs $5,000–$12,000 — often less than a single bathroom renovation — and produces a transformation that affects every room in the house.

At David Reno, interior door and trim renovation is a core part of what we do — as a standalone project and as the finishing layer on every larger renovation we complete. This guide gives you real 2026 Toronto pricing across every door type, trim profile, and project scope, plus the decisions that most affect your result.

Why Interior Doors & Trim Make Such a Big Difference

Interior trim — doors, casings, baseboards, crown moulding — is what interior designers call “the architecture of the room.” It’s the framework that defines how finished and intentional a space feels. And in Toronto’s housing stock, where the majority of homes built between 1960 and 2000 were outfitted with the minimum builder-grade trim package, there’s enormous opportunity.

Consider what happens when you upgrade:

• A hollow-core door replaced with solid-core — the moment you close it, the room feels quieter, more private, more substantial. Sound stops travelling between rooms the way it used to.
• 2-inch builder baseboard replaced with 4-inch profile baseboard — the room feels taller, more finished, more designed. It costs $600–$1,200 for a typical room and takes less than a day.
• Plain door openings fitted with proper casing — openings that used to look unfinished now look intentional. The wall-to-door transition is clean and architectural.
• Crown moulding added to a living room — the ceiling line anchors the room. One of the oldest architectural tricks in home design, and still one of the most effective.

These changes are especially powerful when combined with fresh paint — a standard two-coat repaint paired with new trim and doors is often the most transformative renovation a Toronto homeowner can do before selling.

Interior Door Types & Costs

Door Hardware: Handles, Hinges & Locks

Door hardware is a small cost item that has a disproportionate impact on the finished feel of a room. Mismatched, builder-grade handles undercut even the most beautiful door. Consistent, quality hardware throughout a home — all in the same finish — elevates every room.

Popular finishes in 2026: Matte black is the dominant trend in Toronto new builds and modern renovations. Brushed gold (champagne) is popular in warmer or transitional interiors. Satin nickel remains the classic neutral that works in almost every home. Avoid mixing finishes across rooms — consistency reads as intentional design.

Trim Types & Costs

Painting Doors & Trim

New doors and trim need paint or stain to look finished. This is where many door and trim renovation budgets run short — the trim looks unfinished and sits unpainted for months. Build paint into your project from the start.

Colour recommendation 2026: White remains the universal choice for trim in Toronto homes — pure white (Benjamin Moore Chantilly Lace, Sherwin-Williams Extra White) reads clean and crisp. Warm white (White Dove, Alabaster) suits warmer or more traditional interiors. Black doors as a contrast to white trim is a strong 2026 trend that works particularly well in transitional and modern homes.

Whole-Home Project Cost Examples

Factors That Affect Your Total Cost

1. Opening Size & Condition

On-site adjustments are common — some doors go in straight; others require trimming, hinge repositioning, or jamb shimming to function correctly. Older Toronto homes with settling or uneven framing often need more adjustment work per door. Budget $50–$150 per door for adjustment work in pre-1990 construction.

2. Existing Trim Removal

Removing old baseboards and casing adds labour time. In homes where trim was installed with construction adhesive (common post-2000), removal is more damaging to drywall — expect patching and touch-up. Budget $1–$2 per linear foot for removal and any drywall repairs needed.

3. Ceiling Height & Room Complexity

Crown moulding on 9-foot or 10-foot ceilings requires taller ladders and more precise cutting — adding 15–25% to labour. Cathedral ceilings require compound angle cuts that few carpenters execute cleanly without experience. Always confirm your contractor has worked with vaulted ceilings before quoting crown moulding on these spaces.

4. Door Size — Non-Standard Openings

Labour typically runs $100 to $500 per door depending on complexity. Standard 80″ × 32″ doors are the most affordable to replace — they’re pre-hung and widely available. Non-standard heights (84″, 96″) or widths require custom-ordered or custom-cut doors, adding lead time and cost. Toronto’s older housing stock frequently has non-standard rough openings — always measure before ordering.

5. Painting Finish Level

A brushed-on semi-gloss finish is standard for trim and adequate for most applications. Spray finish produces a smoother, factory-quality result — particularly noticeable on flat-panel doors. Spray finish adds $60–$120 per door but is worth it for high-visibility statement doors (black doors, feature entryways).

6. Number of Doors — Volume Efficiency

Replacing one door costs proportionally more than replacing ten. Door and trim projects have fixed mobilization costs (trip, setup, disposal) that are shared across the project. A 10-door replacement costs less per door than a 3-door replacement. If you’re considering a partial replacement, think about whether the additional cost to do the full home is worth it.

Installation Timeline

Important: The home is fully liveable throughout a door and trim renovation — this is interior finish work, not a structural project. Rooms are accessible while work is in progress in other areas, and there is no need for temporary accommodation.

How David Reno Can Help

Interior door and trim renovation is a core part of David Reno’s finish carpentry and interior renovation services. We handle every component — from door supply and installation through casing, baseboards, crown moulding, and painting.

Every major renovation David Reno completes — kitchen, bathroom, basement, home addition — ends with a door and trim finish pass. We understand how the final details define the quality of the project. And for clients who want a standalone door and trim transformation without a larger renovation, we deliver the same standard of craftsmanship.

What David Reno handles:

• On-site assessment: We measure every door opening, assess frame condition, and provide written fixed-price quotes — no surprises for frame repairs or adjustment work
• Door specification & supply: We source solid-core, French, pocket, and barn doors from our supplier network — you choose the style and finish
• Door installation: Hanging, shimming, adjusting — doors that close smoothly and latch properly in older Toronto homes with settling frames
• Hardware installation: All hardware installed, aligned, and tested — consistent finish throughout
• Casing installation: Custom profile casing cut precisely to each opening — clean mitered corners, no gaps
• Baseboard installation: Old baseboard removed, new baseboard fitted — including scribe cuts for out-of-plumb walls (very common in older Toronto homes)
• Crown moulding: Compound miter cuts, coped corners, consistent reveal — this is skilled work we execute on every project
• Drywall repairs: Any damage from baseboard removal patched and ready for paint
• Painting: We can include a full trim paint pass as part of the project or leave primed and ready for your own painter
• Written warranty: All David Reno work is warranted in writing

Tips to Save Money on Interior Doors & Trim

1. Upgrade Hardware First

If budget is tight, start with hardware. A consistent set of quality levers throughout the home costs $800–$1,500 and upgrades every door you touch — even if the doors themselves haven’t changed. It’s the fastest, most visible impact for the smallest investment.

2. Upgrade Solid-Core in Bedrooms & Bathrooms Only

Sound isolation matters most in bedrooms, bathrooms, and home offices. Closet doors and utility room doors can remain hollow-core without meaningful impact. Strategic solid-core upgrades cost 30–40% less than a full-home replacement.

3. Start with Baseboards

If you can only do one trim upgrade, do baseboards. They run continuously through every room and have more visual impact per dollar than any other trim element. New 4-inch baseboards throughout a main floor cost $650–$1,600 and transform the space.

4. Combine with Adjacent Renovations

Door and trim work combined with another David Reno project (bathroom, basement, open concept) shares mobilization, trades scheduling, and disposal costs. Adding trim work to a bathroom renovation adds far less in proportional cost than doing it as a standalone project.

5. Buy Doors in Standard Sizes

Standard 80″ × 30″ or 80″ × 32″ doors are widely stocked and significantly cheaper than custom sizes. If an opening is close to standard size, reframing to standard is often cheaper than ordering custom. Confirm sizing before purchase.

6. Paint Yourself

Painting trim is the one part of this project that motivated DIYers can execute well with patience and the right tools (quality angled brush, semi-gloss paint, painter’s tape). Saving $1,500–$2,500 on trim painting leaves more budget for the finish carpentry — where professional installation makes the most visible difference.

Frequently Asked Questions

How much does interior door replacement cost in Toronto in 2026?

Interior door replacement in Toronto costs $350–$700 per door for a standard hollow-core door fully installed (door, hardware, casing, labour), or $550–$950 for a solid-core upgrade. Labour for a standard interior door swap runs $100–$300 per door in Toronto — slightly higher than smaller Ontario markets due to GTA wage rates. A full 10–12 door project for a typical Toronto home costs $4,500–$12,000 depending on door type, hardware grade, and whether trim work is included.

Is solid-core worth the upgrade from hollow-core?

Yes — consistently. The difference in sound isolation, weight, and feel is immediately noticeable. The premium is typically $150–$250 per door. For bedrooms, bathrooms, and home offices where privacy matters, solid-core is the standard David Reno recommends. For closets and utility rooms, hollow-core remains adequate.

How much do new baseboards cost in Toronto?

Baseboard installation in Toronto costs $4–$10 per linear foot installed, including removal of existing baseboards. A standard Toronto room (12 × 14 ft) has approximately 50 linear feet of baseboard perimeter — costing $250–$500 installed. A main floor refresh (3 rooms + hallway, 150 lf) costs $750–$1,500. Painting is additional.

Do I need a permit for interior door or trim work in Toronto?

Replacing a door in an existing opening with a unit of the same size generally does not require a permit in most Canadian municipalities. No permit is needed for like-for-like interior door replacement, baseboard, or trim installation. A permit is required if you’re creating a new opening in a wall (especially load-bearing), widening an existing opening, or if structural work is involved. David Reno confirms permit requirements at the estimate visit for any project involving wall modifications.

How long does a whole-home door and trim renovation take?

A complete door and trim renovation — all doors, hardware, casing, and baseboards throughout a typical Toronto home — takes approximately 5–10 business days. Adding crown moulding or wainscoting adds 1–3 more days. Painting is typically done last and adds 3–5 days. The home is fully liveable throughout — this is interior finish work, not structural.

What’s the best door colour for Toronto homes in 2026?

Black interior doors are the single most popular statement door choice in Toronto’s renovated homes in 2026 — they work in modern, transitional, and even traditional interiors when the trim is white. Classic white (semi-gloss or satin) is the safe, universally appealing choice for doors that blend rather than feature. Natural wood stain finishes are making a comeback in Craftsman and warm modern interiors. Choose based on your overall interior palette — doors should complement the trim and wall colours, not fight them.
