Can you work on hillside homes in Palomares Hills and Five Canyons?

Yes. Independent providers handle the access-sensitive hillside lots — decks, gutters, and exterior work — with everything documented in before-and-after photos.

Are providers background-checked and insured?

Yes — every independent provider is background-checked, identity-verified, and insured before their first job, with general liability coverage on every job.

Is aluminum wiring & knob-and-tube replacement in Castro Valley backed by a warranty?

Yes. Your pro backs every Castro Valley job with a workmanship warranty of at least 30 days on general repairs and at least 90 days on tile, flooring, doors, and windows, and your pro may offer more. If covered work isn't right inside that window, your pro makes it right at no charge.
