Overview
Home remodeling in Altadena
Sage n' Slate is a senior-led design-build firm working throughout Altadena and the surrounding Los Angeles County area. The neighborhood is defined by craftsman bungalows and mid-century homes set against the san gabriel foothills, and our work respects that context — we remodel and build homes that read as if they were always meant to be there. We cover ZIP code 91001 and pull permits through Los Angeles County.

Process
How a project runs
Every Altadena engagement follows the same disciplined sequence.
Discovery
a no-cost site walk and conversation about how you actually live in the home.
Design
drawings, materials, and a transparent line-item budget developed together.
Build
senior trades on site, weekly client check-ins, and a single point of accountability.
Walk-through
a punch-list closeout, written warranty, and a clean handoff of the finished home.
Craft
We build with materials that hold up for decades — rift-cut oak, honed stone, hand-troweled plaster, unlacquered brass. The detailing is what makes a Altadena remodel feel quietly resolved rather than newly built.
