Steel entry doors installed in Ontario typically start around $2,057, standard fiberglass doors start around $2,112, and a custom fiberglass entry system with sidelights, upgraded glass, and a multi-point lock can run up to roughly $10,962. The width of that range exists for a real reason: door type, hardware, and glass configuration move the price far more than any single "average" figure captures, and lumping every entry door into one broad number, the way general retail estimates often do, hides the decision that actually matters most.
Steel entry doors: the lower-cost, high-durability option
A steel entry door typically sits at the lower end of installed pricing, starting around $2,057 for a standard configuration. Steel's lower cost comes from the material itself, not reduced quality: a steel slab is less expensive to manufacture than an insulated fiberglass panel, while still offering strong impact resistance and security. Where steel costs more is in add-ons, upgraded multi-point locking, decorative glass inserts, or sidelights, each of which adds to the base price the same way it would on any door material.
Fiberglass entry doors: a mid-to-upper range investment
Standard fiberglass entry doors start slightly higher than steel, typically around $2,112 installed, reflecting the material's higher manufacturing cost and its ability to hold a wood-grain textured, stainable finish that steel can't replicate. Fiberglass also resists warping, denting, and rust in a way steel and real wood both struggle with over time, particularly through Ontario's humidity swings and freeze-thaw winters, which is a real factor in the price difference, not just a finish preference.
Custom fiberglass systems: where the range tops out
A fully custom fiberglass entry system, sidelights on one or both sides, upgraded decorative or sandblasted glass, a premium multi-point lock, and a stained or painted specialty finish, can run up to approximately $10,962 installed. This isn't a single door anymore; it's a coordinated assembly of multiple matched units finished together, which is why the top of the range reflects a meaningfully different scope of work than a standard single-slab replacement.
What actually moves the price
The variables that move a quote within these ranges are straightforward once they're separated out: door material (steel vs. fiberglass), whether sidelights are included, glass style (clear, frosted, sandblasted, or decorative), lock hardware (standard deadbolt vs. multi-point system), finish (factory paint vs. stained wood-look), and whether the installation is a standard-size retrofit or a custom or resized opening.
Why a big-box installed estimate isn't always apples-to-apples
General retail installation pricing often bundles product and labour into one broad range without breaking out what specifically drives cost within it. A specialized installer's pricing tends to reflect a narrower, more predictable scope, in-house measurement, sourcing, and installation as one coordinated service, rather than a retail markup plus a separately contracted installation crew. Comparing quotes side by side means confirming whether each number includes the same scope: removal of the old door, disposal, hardware, and finish work, not just the door slab itself.
Rebate note: Entry door replacements may qualify for up to $100 per rough opening under the Home Renovation Savings™ program when you bundle two or more eligible upgrades. ENERGY STAR® certified products are required, and eligibility and approval depend on the current program requirements and administrator, with an energy assessment needed before work begins.
