What Our Clients Say
“Gadget Construction transformed our 1940s Sunset District home into exactly what we envisioned. They handled everything — permits, inspections, the works. The crew showed up on time every single day and left the site spotless. We couldn't be happier with the result.”
Michael R.
Complete Remodel — Sunset District, SF
“After the last earthquake, we knew our foundation needed work. Gadget Construction came out the next day, explained everything in plain English, and gave us a detailed estimate. The work was done on schedule and on budget. We sleep better at night now.”
Sarah & David L.
Concrete Foundation — Bernal Heights, SF
“We wanted a deck that could handle San Francisco weather without constant maintenance. Gadget Construction recommended composite and walked us through every option. Six months in and it still looks brand new. Best investment we've made in this house.”
Jennifer K.
