An open-plan kitchen and living room is one of the most popular renovation projects. However, removing a load-bearing wall requires careful planning. Here are the steps to do it safely.
How can you tell if a wall is load-bearing?
A load-bearing wall supports the weight of floors, the roof or joists. It generally runs perpendicular to the joists and is often near the centre of the house. However, only a professional can confirm this. That is why an inspection is the first step.
Step 1: engineering plans
A structural engineer then calculates the loads and sizes the replacement beam in steel or engineered wood. The plans also specify posts and supports extending down to the foundation, ensuring the weight of the house is transferred safely.
Step 2: the municipal permit
With the plans ready, an application is submitted to the municipality for a building permit. Most municipalities require one to remove a load-bearing wall. A permit also helps protect your insurance coverage and your home’s resale value.
Step 3: temporary shoring
On the day of the work, the contractor installs temporary supports on both sides of the wall. This keeps the structure supported throughout the process.
Step 4: remove the wall and install the beam
The wall is then demolished, electrical wiring, plumbing or ventilation is relocated if needed, and the beam and posts are installed according to the plans. The beam can be concealed in the ceiling or left exposed, depending on the desired style.
Step 5: finishing
Finally, drywall, joint finishing, paint and flooring are restored where the wall once stood. The result is a spacious, bright room that looks as though it has always been there.
How much time should you allow?
Once the plans and permit are obtained, the work itself often takes a few days to two weeks, depending on complexity and finishes. Preparing the plans and obtaining the permit can take a few additional weeks.
Mistakes to avoid
- starting without engineering plans
- forgetting the municipal permit
- underestimating the relocation of plumbing or electrical wiring
- overlooking supports down to the foundation
