Reviews

What San Jose homeowners say.

"Full Home added a 500 sq ft master suite over our garage. They matched the stucco perfectly and had the framing inspection passed in two weeks. Zero surprises on the final bill."

James L.
Master Suite Addition

"Our 1980s galley kitchen now flows into the living room thanks to the beam they dropped in. The crew protected our hardwood floors and cleaned up every night. We cooked dinner in the temp kitchen they set up in the garage."

Alicia R.
Kitchen Remodel

"They converted our detached garage into a 600 sq ft ADU. The separate electrical panel and tankless water heater were installed to code, and the inspector signed off without a single correction. We’re already collecting rent."

Kevin M.
