Home Addition Contractors in Los Angeles CA
Adding a new wing to an LA house is a massive structural undertaking that goes way beyond just framing a few walls. Most older properties in the city have foundation footings that weren’t designed to carry the load of a modern second story or a heavy room extension. As home addition contractors in Los Angeles CA, we focus on the trenching and the rebar cages first. We dig down to the bedrock or the compacted soil to make sure the new structure doesn’t pull away from the main house over time. Whether you are adding a master suite or a sunroom, we prioritize the seismic anchors and the foundation bolts needed to keep the whole building tied together.
A successful addition is only as good as the tie-in point at the existing roofline. We handle the complex rafter cuts and the flashing to make sure you don’t end up with a leak where the old house meets the new one. By doing the structural steel-work and the heavy framing ourselves, we cut out the typical sagging and settling issues that fail a city inspection. We provide a clean, level transition between your old floor plan and the new square footage so the transition looks like it was always there. We build these extensions to handle the shifting California ground and the high-wind loads of a coastal or hillside lot.
