Complete Guide to Door Replacement Costs in Canada
Complete Guide to Door Replacement Costs in Canada
Replacing a door in your home sounds simple — but once you factor in the door itself, the frame, structural modifications, hardware, finishing, and labour, the total cost can range dramatically. Most Alberta homeowners budgeting for a front door replacement should plan for $3,500–$9,738, depending on door type, material, and whether structural work is required. A full door replacement project including frame and structural modifications runs $9,738 at the high end, while a standard single pre-hung fiberglass entry door with one sidelight comes in around $3,500. Patio door replacements fall in the $3,500–$5,400 range depending on material.
This guide breaks down what you will actually pay, what drives costs up or down, what permits and licensing you need, and how to plan your budget before the first contractor sets foot on your property.
What You'll Actually Pay: Door Replacement Costs by Project Type
The single biggest variable in door replacement pricing is what you're replacing and what you're replacing it with. A like-for-like swap of a standard exterior door costs far less than a conversion that widens an opening, adds sidelights, or changes the door style entirely.
The data below reflects Alberta project costs. Costs in other provinces will vary based on local labour rates, material availability, and regional code requirements.
Exterior Front Entry Doors
| Project Type | Cost Range |
|---|---|
| Pre-hung painted single fiberglass front entry door with one sidelight, supply and install | $3,500 |
| Fiberglass front door with frosted half-glass panel, painting, installation, and lock hardware | $3,900 |
| Standard single unfinished pre-hung exterior solid wood door (minimum) | $4,500 |
| Oversized fiberglass front door with dual sidelights, ornamental glass, stained finish, premium hardware | $8,500 |
| Exterior solid wood door installation (custom, premium) | $5,000–$15,000 |
| Full door replacement including frame and structural modification | $9,738 |
The gap between $3,500 and $9,738 for a front entry door isn't accidental — it reflects the difference between a standard pre-hung unit dropped into an existing rough opening and a custom-built, oversized door system that requires framing changes and premium materials throughout.
Fiberglass sits at the middle of the cost spectrum and is one of the most popular choices for Canadian homeowners. It resists warping and swelling from freeze-thaw cycles, holds paint and stain finishes well, and offers better thermal performance than steel at similar price points. A basic painted fiberglass front door with a glass panel and installation runs around $3,900, while a premium oversized fiberglass unit with dual sidelights and ornamental glass climbs to $8,500.
Solid wood doors carry the widest cost range. At minimum, a standard single unfinished pre-hung wood exterior door starts at $4,500, but custom wood doors — particularly those with premium species, carved details, or architectural glass inserts — can reach $15,000 or more.
Patio Doors
| Project Type | Cost Range |
|---|---|
| Fiberglass patio door replacement, supply and install | $3,500–$4,000 |
| Aluminum patio door replacement, supply and install | $3,600–$5,400 |
| Wood patio door replacement, supply and install | $3,850–$5,800 |
| Aluminum patio door (alternative scope) | $5,000 |
| Fiberglass French-style garden doors with blinds inside glass | $4,200 |
Patio door replacement costs cluster in a tighter band than entry doors because the rough opening size is typically standardized. The main cost driver here is material. Fiberglass patio doors offer the best thermal performance and are the lowest-maintenance option over time, coming in at $3,500–$4,000 installed. Aluminum doors are durable but can be less thermally efficient without a proper thermal break, and cost $3,600–$5,400. Wood patio doors are the most expensive to maintain long-term but offer the warmest aesthetic, running $3,850–$5,800 installed.
If you want to convert a standard patio door to a French-style garden door configuration, budget for $4,200 for a fiberglass version with blinds integrated inside the glass — a popular choice that eliminates the need to clean between blind slats.
French Doors and Structural Projects
| Project Type | Cost Range |
|---|---|
| Custom wood French doors with triple-pane glass and structural modifications | $5,500–$8,000 |
| Full door replacement project average (all types) | $8,933 |
| Door installation project average | $6,518 |
| Interior door installation average (multiple doors) | $5,796 |
When a door replacement requires structural modification — widening an opening, removing a load-bearing section of wall, or adding a new opening where one didn't exist — costs rise significantly. Custom wood French doors with triple-pane glass and the framing work required run $5,500–$8,000. Once structural modifications are in scope, you need more than just a skilled installer: you likely need a licensed contractor, and potentially an engineer.
What Drives Door Replacement Costs Up or Down
Understanding the cost levers helps you make smarter decisions before you request quotes. Most homeowners are surprised to find that the door itself is often not the largest single line item — labour, framing, finishing, and hardware regularly match or exceed the door cost.
Material Choice
Material is the first decision you'll make and one of the most consequential for budget. Steel doors are generally the least expensive upfront and offer good security, but they can dent and are prone to thermal bridging at the frame. Fiberglass costs more than steel but performs better thermally, mimics wood grain convincingly, and doesn't require the maintenance of real wood. Solid wood commands a price premium at every tier — from the $4,500 minimum for a basic pre-hung unit to $15,000 or more for custom architectural pieces — but nothing matches its aesthetic impact for a high-end home.
Door Size and Configuration
Standard door sizes fit into standard rough openings and require minimal labour beyond installation. Non-standard sizes — oversized single doors, double door configurations, transoms, sidelights — require framing modifications that add both material and labour costs. A single sidelight can add several hundred dollars to an entry door project. Dual sidelights with ornamental glass push a fiberglass entry door project to $8,500.
Structural Modifications
This is the biggest single cost driver. If your project requires widening the opening, installing a new header, or modifying framing, you're looking at a substantially larger project. In Alberta, the Alberta Building Code requires a structural engineer review and stamped drawings for any door installation that affects a load-bearing wall or creates an opening wider than four feet. Budget for engineering fees on top of the installation cost when structural work is in scope, and expect the project to take longer.
For French door installations replacing a sliding patio door, framing modifications are often required. These projects typically take one to two days from removal through trim work and finishing, assuming the rough opening doesn't require significant structural changes.
Hardware and Finishing
A bare-bones installation includes a basic lockset. Premium deadbolts, multi-point locking systems, smart locks, decorative handles, and coordinated hinge hardware add up quickly. Budget $200–$800 for quality hardware depending on security and aesthetic requirements — and make sure your installer's quote includes hardware, not just the door and labour, or you'll be surprised at the final invoice.
Finishing — painting, staining, and sealing — is another variable. Some doors come pre-painted or pre-finished; others require field finishing. A custom stained finish on an oversized fiberglass door is included in the $8,500 price point, but not all quotes bundle this. Clarify whether finishing is included before you sign.
Labour and Local Market Conditions
Labour rates vary across the country. Remote communities pay more for skilled installation labour. Urban markets in Alberta have higher baseline labour costs than smaller centres. Multi-door projects — like interior door installations across an entire home — benefit from economies of scale, which is reflected in the $5,796 average for interior multi-door projects.
Permits, Licensing, and Code Requirements
Door replacement is not uniformly a permit-free job. Whether you need a permit depends on the scope of work, the province, and in some cases the specific municipality.
Alberta
The Alberta Building Code sets the standards for door installations, including clear doorway widths, energy performance requirements, and structural specifications. Key requirements include:
- Accessibility: Alberta Building Code requires a minimum 32-inch clear doorway width for wheelchair accessibility in renovations; 36 inches is recommended for best practice.
- Structural openings: A structural engineer review and stamped drawings are required for any door installation affecting a load-bearing wall or creating an opening over four feet wide.
- Energy performance: Doors — like windows — must meet the Alberta Building Code's thermal performance standards, which are more stringent than in many other provinces given Alberta's climate.
- Licensing: General contractors and trade professionals working on door installations must be properly licensed through Alberta's apprenticeship and industry training system. Work on licensed trade systems (electrical, gas) requires the appropriate certified professional.
- Worker coverage: Contractors must maintain coverage through WCB Alberta (Workers' Compensation Board of Alberta). Ask to see your contractor's WCB clearance certificate before work begins.
If your door replacement project requires structural modifications, don't assume your contractor will pull the necessary permits automatically. Ask explicitly, confirm who is responsible for the permit application, and get documentation that the permit has been issued before work starts.
New Brunswick
In New Brunswick, a building permit may be required when replacing an entire door assembly, particularly in heritage areas such as Uptown Saint John where heritage preservation overlays apply. Before proceeding with a full door assembly replacement in New Brunswick, consult the Technical Safety Authority of New Brunswick and your local municipality to determine whether a permit is required. Worker protection falls under WorkSafeNB, and the NB Building Code governs minimum installation standards.
Ontario
Ontario door projects are governed by the Ontario Building Code, with safety oversight through the ESA (Electrical Safety Authority) and TSSA (Technical Standards and Safety Authority) for any work touching electrical or fuel-burning systems. Worker compensation falls under WSIB (Workplace Safety and Insurance Board). If your door project involves electrical work — power for a smart lock, exterior lighting, or a heated threshold — ensure your contractor uses a licensed electrician.
British Columbia
In British Columbia, the BC Building Code sets standards, Technical Safety BC oversees safety-related work, and worker coverage falls under WorkSafeBC. As with Alberta, structural modifications require permits and potentially engineering review.
The universal rule across all provinces: if you're not sure whether a permit is required, call your local building department and ask. Unpermitted structural work creates liability issues when you sell your home, and it can void your insurance coverage for related claims.
How to Compare Quotes and Avoid Costly Mistakes
Getting the right price means more than finding the lowest number. A quote that omits disposal fees, hardware, finishing, permit costs, and structural contingencies can look attractive on paper and deliver a nasty surprise at invoice time.
Get At Least Three Quotes
Always get at least three quotes for any door replacement project. This is not simply about finding the cheapest price — it's about understanding the market rate, identifying what each contractor is including, and assessing who communicates clearly and completely. The contractor who provides the most detailed written quote — itemizing door supply, hardware, installation labour, disposal, finishing, and permit fees separately — is usually the most trustworthy.
Understand What's in the Quote
Before accepting any quote, confirm it includes:
- Supply of the door unit (including frame and weatherstripping)
- Removal and disposal of the existing door
- Installation labour
- Hardware (lockset, deadbolt, hinges — or confirm these are excluded and budget separately)
- Finishing (painting or staining, if applicable)
- Any required framing or structural work
- Permit fees (if required)
- HST or GST
A door replacement quote that omits structural contingencies is only valid if the existing rough opening is confirmed to be the correct size and in good condition. If your existing frame has rot, moisture damage, or an undersized header, those costs will be added on-site. Ask contractors explicitly what they will do if they find rot or structural issues during removal, and get a contingency range.
Check Licensing and Insurance
In Alberta, verify that your contractor is licensed through the appropriate apprenticeship and industry training system. Request a copy of their WCB Alberta clearance certificate. Ask for proof of liability insurance — a minimum of $2 million in general liability coverage is standard for reputable contractors.
Do not pay more than 10–15% as a deposit before work begins. A contractor who demands 50% upfront before materials are ordered is a red flag.
Timing and Scheduling
A standard door replacement takes one to two days for most projects without structural complications. If your project involves framing modifications, custom-order doors with lead times of four to twelve weeks, or heritage area permits in New Brunswick, build extra time into your planning. Scheduling door replacement in shoulder seasons (spring and fall) typically offers better contractor availability than peak summer.
Budget Planning: What to Set Aside Before You Start
Use the ranges below as your baseline planning figures. These reflect Alberta data; if you are in another province, expect regional variation in both labour and material costs.
| Project Scope | Budget Range |
|---|---|
| Basic fiberglass entry door, pre-hung, no sidelight | $3,500–$3,900 |
| Fiberglass entry door with one sidelight | $3,500 |
| Standard solid wood exterior door (unfinished, minimal scope) | $4,500+ |
| Fiberglass patio door replacement | $3,500–$4,000 |
| Aluminum patio door replacement | $3,600–$5,400 |
| Wood patio door replacement | $3,850–$5,800 |
| French-style garden doors with glass and custom fit | $4,200–$8,000 |
| Oversized custom fiberglass entry door with dual sidelights | $8,500 |
| Full door replacement with frame and structural modification | $9,738 |
| Exterior solid wood door (premium/custom) | $5,000–$15,000 |
| Interior door installation (multi-door project) | $5,796 (average) |
Add a contingency of 10–15% for hidden rot, structural surprises, or hardware upgrades you decide on mid-project. For projects involving structural modifications, increase your contingency to 20%.
Before You Start: Action Checklist
Use this checklist before you hire a contractor or purchase a door:
- Measure your existing rough opening — confirm width, height, and depth before ordering any door unit
- Identify load-bearing walls — if your project involves widening an opening or removing framing, consult a structural engineer before proceeding
- Check permit requirements — contact your local building department; in New Brunswick, check heritage overlay requirements; in Alberta, confirm with the Alberta Building Code requirements for your specific scope
- Set your material priority — fiberglass, steel, or wood? Each has different long-term maintenance and performance implications for Canadian climates
- Get at least 3 quotes — itemized, written, including all materials, labour, hardware, finishing, disposal, and permit fees
- Verify contractor credentials — Alberta: licensed through Alberta Apprenticeship and Industry Training, WCB Alberta clearance certificate, liability insurance; adjust for your province accordingly
- Confirm the timeline — custom doors often have 4–12 week lead times; plan around your schedule
- Budget for hardware separately if not included in the quote — quality deadbolts and multi-point locks add $200–$800
- Ask about the warranty — what does the manufacturer warranty cover, and what does the installation warranty cover?
- Plan for finishing — confirm whether painting or staining is included; exterior doors in Alberta's climate require high-quality exterior-grade finishes to prevent early deterioration
- Document the work — keep permits, inspection records, and warranty documents for your home file; this protects you at resale
Door replacement is one of the highest-visibility renovations you can make to a home, with meaningful impacts on curb appeal, energy performance, and security. Whether you're spending $3,500 on a straightforward fiberglass front door swap or $9,738 on a full structural replacement project, the difference between a satisfying outcome and a frustrating one comes down to preparation: understanding what you're buying, hiring properly licensed contractors, pulling the right permits, and budgeting realistically for the full scope of work — not just the door itself.
