Common questions
Do I need an engineer to remove a load-bearing wall?
Yes. In Ontario, removing a load-bearing wall needs a building permit, and the city will ask for an engineered beam design. We confirm what the wall is carrying from the floors and roof above, size the replacement beam, and design the posts and footings that take the load down to the foundation. You get sealed drawings for the permit, and we answer any questions the city sends back.
Will I need an LVL or a steel beam?
It depends on the span, what's above the wall and whether you want the beam hidden in the ceiling (flush) or hanging below it (dropped). LVL (engineered wood) suits most shorter residential spans and is easy for a framer to install. Steel is used for longer spans, heavier loads or a flush beam where there isn't enough depth for wood. We specify the beam size, bearing length, posts, footings and connections, so your contractor knows exactly what to install.
Do I need a permit for underpinning?
Yes. Underpinning changes the foundation, so municipalities require a building permit with engineered drawings.
How much will it cost?
Every project is different. Send us the details and we’ll give you a clear quote before any work starts.
Can you work with my contractor or designer?
Yes. We coordinate directly with your contractor or designer and provide drawings they can build from.
