A practical cost breakdown from licensed structural engineers
It is the first question almost every homeowner asks us: what will it cost to remove this wall? The honest answer is that it depends on the wall, but the costs are more predictable than most people expect once you understand how they break down. This guide covers the two parts of every load-bearing wall removal in Ontario: the engineering and permit work, and the construction itself.
The Short Answer
For a typical single load-bearing wall in the Greater Toronto and Hamilton Area, most homeowners should budget roughly $10,000 to $13,500 in total for engineering, permit preparation and construction. A standard dropped beam sits at the lower end of that range; a steel beam hidden flush in the ceiling sits at the upper end. Finishing work, municipal permit fees and any new footings are additional.
The Two Parts of the Cost
- Engineering and permit: a structural engineer designs the beam and supports, prepares stamped drawings, and the drawings are submitted to your municipality for a building permit.
- Construction: a contractor installs temporary supports, removes the wall, installs the new beam and posts, and finishes the space.
Keeping these separate makes it much easier to compare quotes and avoid surprises.
Engineering and Permit Costs
A typical load-bearing wall removal package from our team looks like this:
- Site visit and engineering design by a Professional Engineer: about $1,400. We measure the existing structure, confirm what the wall is carrying, and size the beam, posts and connections down to the foundation.
- Architectural drawings: about $1,125. Most municipalities require existing and proposed floor plans with the permit application.
- Permit application handling (optional): $425 if you would like our team to submit and manage the application with the city.
That brings a typical engineering and permit package to about $2,950 before HST. Municipal building permit fees are charged separately by your city and vary between Oakville, Burlington, Hamilton, Mississauga and other municipalities.

Construction Costs
We do not perform construction, but we review a large number of contractor quotes. In our area today, contractors typically charge:
- About $7,000 to remove a wall and install a standard dropped beam (wood or LVL sitting below the ceiling joists).
- About $10,000 for a steel beam installed flush within the ceiling, which takes more labour and coordination.
- About $3,500 per new footing, if the posts carrying the beam need new support in the basement.
Contractor quotes usually include demolition and disposal, temporary shoring while the wall is removed, and installation of the beam and posts. Check carefully whether yours includes:
- Moving electrical, plumbing or HVAC ducts that run through the wall
- Drywall, taping, priming and painting
- Flooring repairs where the wall used to stand
Always confirm exactly what a contractor's quote includes and excludes before you sign.
Two Worked Examples
Standard dropped beam between a kitchen and living room:
- Engineering and permit package: about $2,950
- Construction: about $7,000
- Typical total: about $10,000, plus finishing and municipal fees
Flush steel beam for a clean, uninterrupted ceiling:
- Engineering and permit package: about $2,950
- Construction: about $10,000
- Typical total: about $13,000, plus finishing and municipal fees
If a new footing is needed, add about $3,500 per footing. These figures are a guide only; every home is different, which is why a site visit comes first.
What Drives the Cost Up or Down
- Span: longer openings need deeper or stronger beams, often LVL or steel.
- What is above the wall: a wall carrying a second floor and roof is a bigger job than one supporting only attic space.
- Flush or dropped beam: a hidden beam looks cleaner but costs more to install.
- Foundation support: concentrated loads at the posts may need new footings.
- Services in the wall: ducts, plumbing stacks and wiring all add cost when they have to move.

How to Keep Costs Under Control
- Bring in the engineer early. Knowing the beam size and support locations before you collect contractor quotes means every contractor prices the same job.
- Consider a dropped beam where appearance allows; it can save around $3,000.
- Plan the finishes at the same time so flooring and ceiling repairs are not an afterthought.
- Never skip the permit. Unpermitted structural work can cause problems with insurance and when you sell your home.
