Most homeowners in Montreal should request a quote for a finished metal staircase, fabricated and installed. Current prices are on our website. Simple, short runs sit near the low end; wide, multi-landing or heritage-sensitive stairs push toward the top. Ask every contractor for an itemised quote that separates materials, finish, installation and permit costs.
TL;DR:
- Material choice affects both upfront cost and upkeep: painted or powder coated steel is usually cheapest, while stainless costs most and needs the least maintenance.
- A guardrail is required when a surface is more than 60 cm above ground; minimum height is 90 cm or 107 cm, depending on the drop.
- Montreal calculates residential permit fees at $9.80 per $1,000 of work, with a $167.40 minimum; an understated project total can cause inspection problems.
- Permit review can add several weeks, and winter weather can delay footing and anchoring work, so begin approvals before setting an installation date.
- Send every bidder identical photos, rise and run measurements, access notes, finish preferences, and permit status; request itemized costs and verify licensing.

What goes into the price of exterior metal stairs?
A quote is a sum of a few predictable pieces. Knowing them lets you compare two bids line by line instead of just by the bottom number.
- Material: Painted or powder-coated steel is the usual budget choice. Aluminum resists rust and weighs less. Stainless costs the most but needs the least worry. Galvanized steel sits in the middle on price and holds up well against road salt.
- Shop fabrication: Laser cutting, bending, profile rolling and welding are billed as labour hours. Work done in one shop keeps tolerances tight and avoids subcontractor markups.
- Finish: Hot-dip galvanizing, with or without a powder-coat topcoat (a duplex system), adds cost up front. It also cuts repainting later. See our notes on galvanizing, duplex coatings and 316 fasteners.
- Installation: Anchoring, concrete footings below the frost line, labour and any difficult site access all add to the total.
- Permit and drawings: The permit fee is a budget line, and some projects need professional drawings or engineering.
Costs keep moving: Statistics Canada reports that the residential building price index in Montreal rose year over year in the second quarter of 2026, so old quotes age quickly.
Which Montreal site conditions raise the cost?
Montreal winters shape the price more than most buyers expect. The ground heaves, salt can damage exposed steel, and drainage at the base affects a stair’s longevity.
- Frost and drainage: Practitioners point to the “frost well”, where water collects at the base and causes ground heave. Deeper footings and proper site preparation cost more now and prevent a rebuild later. Good drainage channels at the base help keep water away from the footing.
- Borough rules: Some boroughs set stricter aesthetic or material requirements, which can force a pricier finish or a different railing style.
- Geometry and access: Wider stairs, intermediate landings and two-sided handrails mean more steel, more welding and more install time. A tight backyard with no truck access adds labour.
- Engineering: Tall stairs, unusual anchoring or a structure attached to an older building may call for engineering review, which is a separate professional fee.
Pro Tip: Photograph the drainage at the base of your existing stair after rain or snowmelt and send it with your quote request. It tells a fabricator more than measurements alone.
Which code and permit rules affect design and cost?
Code compliance shapes the design, and the design shapes the price. These are the points that show up most often in Montreal quotes.
- Guardrails: The City requires one when a surface is more than 60 cm above ground, at minimum heights of 90 cm or 107 cm depending on the drop, with openings that stop a 100 mm sphere.
- Handrails: Check the applicable handrail requirements for your exterior stair with the City of Montreal or your borough.
- Permit fees: Montreal calculates them as cost of work divided by 1,000, times $9.80, with a $167.40 minimum for strictly residential work. An understated project total can cause trouble at inspection.
- Licensing: The Régie du bâtiment du Québec specifies which work requires a licence. Using an unlicensed contractor can void insurance coverage.
Ask for code compliance as its own line on the quote. For heights, see our guide to reconciling City, RBQ and National Building Code handrail rules.
How long do fabrication, permits and installation take?
Plan on weeks, not days, and plan backwards from the season you want the stair finished.
- Fabrication: A code-ready commercial stair’s fabrication schedule depends on the project and the shop’s workload. Residential stairs are often quicker, depending on shop load.
- Permit review: Local practitioners report that approvals can add several weeks. A visit to the permit counter early helps avoid surprises.
- Installation: Concrete footings and anchoring depend on weather. A winter start can mean waiting for a workable window.
- Contingency: Leave room for borough questions or a drawing revision before you book a hard deadline.

Which Montreal fabricators should you contact?
A local shortlist saves time, and each name below is worth a call. Whoever you choose, ask about code-ready drawings, finish options such as galvanizing or duplex, and whether the stated lead time includes permit-ready documentation.
- Manara Corp: We fabricate in-shop in Lachine and install across Greater Montreal. We cover steel, stainless steel, aluminum and copper. Request a quote for your project.
- Fer Forgé Héritage: A Montreal business that paints and restores forged iron structures, including stairs, railings and balconies, adapted to the local climate. A strong fit for restoration rather than new fabrication.
- HBW Fabrication: A local fabricator worth contacting for fabrication quotes. Ask whether installation is included.
- Balcons Verdun: A local balcony and stair specialist. Ask about residential versus commercial scope and permit documentation.
- Groupe FORGEX: A fabricator to contact for larger or commercial projects. Confirm the lead time and who handles drawings.
- Alumix Aluminium: An aluminum-focused option if you want lighter, rust-resistant stairs. Ask about finishes and railing integration.
We have no published price or lead-time guidance for the other businesses, so request those in writing from each.
How should you prepare to get comparable quotes?
Quotes only compare when every contractor prices the same job. Send the same package to each one.
- Photos of the site and the existing stair, plus measurements of total rise and run.
- Preferred material and finish, such as galvanized or powder-coated steel.
- Permit status and any borough constraints you know about.
- Access notes: gate width, slope, distance from the street.
- A contingency for site unknowns and permit-driven changes. A common rule of thumb is a modest buffer on top of the quote.
- Questions on warranty, code compliance, anchoring details, finish specification and lead times.
Pro Tip: Use our guide to vetting fabricators before you compare price.
Why does local fabrication matter in Montreal winters?
Local, in-shop work can help avoid problems you only see in February. When the person who welds your stair also installs it, nobody can blame the other trade when a footing heaves or a weld corrodes. Corrosion protection and footing depth are worth paying for: a stair that fails costs more than one done properly. Insist on code-ready drawings before you sign.

FAQ
How much does outdoor stair railing cost?
It depends on length, material and finish, and there is no single Montreal figure we can cite. Ask for the railing as its own line in an itemised quote. Our railings page lists residential and commercial options.
What is the average cost to build a staircase?
For exterior metal stairs in Montreal, request a quote for fabrication and installation. Wider stairs, landings and difficult access raise it.
Do I need a permit for exterior metal stairs in Montreal?
Often yes. Montreal bases its fee on the cost of the work, and your borough may add rules. Ask your fabricator to confirm what applies to your address.
Does an exterior metal stair need a guardrail?
Yes, when the surface is more than 60 cm above ground, per the City of Montreal. Minimum heights are 90 cm or 107 cm depending on the drop.
