How Much Does It Cost to Convert Two Garage Doors Into One in the GTA? (2026)

Updated 20267 min read

In the GTA, converting two single garage doors into one double door typically runs $1,500–$3,000 if the centre post is non-load-bearing, and $4,000–$8,000+ if it's load-bearing and needs an engineered beam, stamped drawings, and a permit. Most homeowners land somewhere in the middle. Here's what drives the number.

The single biggest cost factor: is your centre post load-bearing?

Everything hinges on this. If the post between your two doors only holds the door tracks, removing it is straightforward. If it carries the roof or the room above your garage, we have to replace its support with an engineered header beam— and that means structural drawings, a permit, and more labour. It's the difference between a ~$2,000 job and a ~$6,000 one.

You can't tell by looking, which is why every quote should start with a structural assessment (ours is free).

The cost pieces, broken down

  • The new double door:A quality insulated 16×7 steel door installed in Ontario averages around $2,000–$2,300; premium wood, composite, or glass runs higher.
  • Removing the old doors + centre post: Labour to take out both doors, tracks, and the post.
  • Structural engineering (load-bearing only):A structural engineer typically charges $100–$200/hour, with stamped design drawings running $300–$2,500 depending on complexity.
  • Building permit (load-bearing only):Roughly $150–$500 depending on your municipality.
  • The engineered beam + framing (load-bearing only): Materials and the extra labour to install a properly sized beam.
  • Opener: Re-hanging your existing opener is cheapest; a new belt-drive or smart opener adds a few hundred dollars.

Why the cheapest quote can cost you the most

If a company quotes you a suspiciously low price to remove a load-bearing post withouta permit or engineered beam, that's not a bargain — it's a liability. Structural work in Ontario requires a permit and P.Eng-stamped drawings for a reason. Skipping them risks structural damage, a failed home inspection at resale, and no legal recourse.
