Steel doors on GTA warehouses and plazas live a hard life. Road salt and slush sit against the bottom rail all winter, and prime-coat doors rust from the bottom up. Uninsulated doors sweat and frost on the inside. Forklifts, carts and dumpsters dent the skin until it separates from the core, and the door starts to sag on its hinges. Eventually the door either will not close or will not stop drafts, and staff start propping or chaining it. When the frame is still sound, there is no reason to rip it out. A direct swap is faster, cheaper and less disruptive. ## What Is Included in Steel Door Replacement? A new hollow metal leaf fitted to your existing steel frame by our Toronto commercial door installation [/ →](/) crew, with hardware transferred or upgraded and the weather package renewed on exterior doors. ![Installer fitting a new door sweep to a galvanized hollow metal door at a plant](https://placehold.co/1200x750/12151A/f8fafc?text=Installer+fitting+new+door+sweep+to+bottom+of+galvanized+hollow+metal+door+at+plant) The written CAD spec lists: - Leaf: 16-gauge galvannealed or 18-gauge prime-coat steel - Core: polyurethane insulated, polystyrene or steel-stiffened - Preps: hinge reinforcement, lock and strike locations matched to the frame - Weather package: door sweep, thermal threshold, weatherstrip - Hardware: transfer, upgrade or new - Frame: confirmed reuse after inspection Technician confirms specs and price at your free on-site measure. ## Types of Steel Door Swaps ### Exterior service and man-doors Galvanized, insulated, with sweeps and thresholds. The most common swap on plazas and warehouses. ### Interior corridor and utility doors Prime-coat leaves in sound frames, often during a building refresh. ### Pairs Double steel doors with astragals, typical at loading areas and mechanical rooms. ## How Much Does Steel Door Replacement Cost in Toronto? | Scope | Typical range | Main cost drivers | | --- | --- | --- | | Interior prime-coat leaf, hardware transferred | $1,600-$2,400 | Size, preps | | Exterior galvanized insulated leaf, new weather package | $2,400-$3,600 | Core, threshold | | Exterior leaf with new exit device and closer | $3,200-$4,500 | Device, closer, pair | ## When Should a Steel Door Be Replaced? - The bottom rail or skin is rusted through - The door sags or the skin has delaminated - Daylight shows around or under the door - The door is uninsulated on a heated space - Repeated repairs have not fixed latching ## Door Swap vs Door and Frame A door swap keeps wall work out of the job. If the frame is bent, rusted at the base or loose in the wall, a new door will not hang right, and the spec will move that opening to frame replacement. ## Codes and Standards Replacements on rated openings use labelled leaves to keep the assembly valid, exits keep their egress hardware, and doors follow ANSI/SDI A250.8 steel door standards.

FAQ ## Commercial Steel Door Replacement FAQs Straight answers on price, timing, codes and scope. Prices are ranges; a technician confirms specs and price at your free on-site measure. How much does commercial steel door replacement cost in Toronto? Most steel door swaps run $1,600-$4,500 per opening. An interior prime-coat leaf swapped into a sound frame with hardware transferred sits at the low end. An exterior 16-gauge galvanized insulated leaf with a new exit device, closer, sweep and thermal threshold sits at the top. Pairs, vision lites and louvres add to the range. A technician confirms specs and price at your free on-site measure, and the written CAD spec shows each door. Can you put a new steel door in our old frame? Yes, if the frame is square, solidly anchored and not rusted at the base. We check every frame before quoting and mark it reuse or replace in the spec. Galvanized or prime-coat? Galvanized for exterior doors, wash-down areas and anywhere moisture sits. Prime-coat for dry interior doors that will be painted. Do insulated doors make a difference? On heated space, yes. A polyurethane-core door cuts heat loss and stops the inside face from frosting and sweating in winter. Will our existing hardware fit the new door? Usually. We order the leaf with preps matched to your hinges, lock and closer, so most hardware transfers directly. How long does a swap take? A few hours per door on site. Spec-to-install is typically 7-10 business days. Which door brands do you use? Steelcraft, Ceco Door and comparable Canadian hollow metal lines, chosen for availability and the right gauge and core. Do you replace steel doors at Scarborough plazas? Yes. A Wexford plaza recently had both rusted rear service doors replaced with prime-coat hollow metal matched to the existing hardware prep. What if the frame is bent? Then the frame needs replacing as well. See commercial door frame replacement. Still have a scope question? Our spec desk answers the phone.
