Adding a floor puts new load on your walls and foundation. We frame the new storey to the engineer’s design, and build any new footings or underpinning the added load needs.
No waiting on rental stock or another crew

The engineer confirms whether your walls and footings can carry the new floor, and what has to change if not.
New footings under new posts, or underpinning where the existing footings are too small. We do both.
Floor system, walls, roof framing and sheathing, tied into the existing house to the drawings.
Footing and framing inspections booked and passed in order.
Most second storey jobs are thought of as framing. But the new floor’s weight goes down through the walls to the footings. If the engineer finds the footings undersized, that work has to be done before framing starts.
Because we do concrete and framing, one company handles both and keeps them on one schedule. Send the drawings and we’ll price the framing and any foundation work together.







































That’s the engineer’s call. They check the walls and footings and specify any changes. We build to their design.
Yes. New footings and underpinning are our core work, so they are priced and scheduled with the framing.
It depends on the job and the roof work. We plan the sequence with you and your contractor before we start.
Yes. We frame additions for homeowners, builders and renovation contractors.
