Load-bearing wall removal in Markham
Subdivision lots take a crane and a bin, and lots along the Rouge add a conservation authority review. The floor above is shored on both sides, the wall comes out behind dust walls, the beam is set and landed on new footings, and the finishes are patched so the wall was never there. Taking out a load-bearing wall is an engineering job with a demolition inside it: the engineer sizes the beam, the posts and the footings, and the crew shores the floor, cuts the wall and lands the steel.
Markham, on the ground.
Markham is heritage districts in Unionville and Markham Village, 1970s and 1980s subdivisions in Thornhill and Milliken, and newer stock in Cornell and Berczy. In those houses in Markham, the wall between the kitchen and the dining room is the one that usually comes out, and it usually carries the floor above. The Markham brief is usually a second storey on a 1980s house, a rear addition behind a heritage house, or a custom home on a deep Thornhill lot.

Paper first.
A load-bearing wall needs a building permit with an engineer's drawing, and the inspector sees the beam and posts before they are closed in. The City of Markham issues the permit, and heritage designation adds a review to anything visible from the street.
- A building permit with engineered drawings is required in every GTA municipality for any wall that carries load.
- The inspector sees the beam and the posts before they are closed in.
- Ducts, plumbing and wiring moved out of the wall are permitted and inspected with their own trades.
The paperwork wall: WSIB, insurance, licences, the HCRA status and the warranty, on one page and dated.
| Driver | What we look at |
|---|---|
| Span and load | A long opening under two floors needs a bigger beam and posts on new footings. |
| Flush or dropped beam | A beam hidden in the ceiling costs more than one below it, and the joists above decide whether it is possible. |
| Footings | Posts need something to land on, and that can mean new footings through the basement slab. |
| What is in the wall | Ducts, plumbing and wiring that have to move before the wall can go. |
| Finishes | Matching an old hardwood floor across the opening, or refinishing the whole room. |
No price per wall on this site. The engineer's drawing sets the number.
For a load-bearing wall, yes, from the City of Markham, with an engineer's drawing. For a partition wall carrying nothing, usually no. We tell you which at the site walk.
Often. A flush beam sits between the joists so the ceiling stays flat. It costs more than a dropped beam, and what is above decides whether it is possible.
Most can. The engineer confirms the foundation from a test pit, and the lots in Thornhill and Milliken have the room for a crane.
Yes, with a heritage review of anything visible from the street. Additions usually go to the rear and follow the character of the house. We bring that into the design before the permit application, not after.
