Our Services

From rooftop solar to backyard decks, Alpha One Construction handles full home upgrades across Los Angeles.

Solar System Installation

Our NABCEP certified crew mounts 6-14 kW rooftop arrays with Enphase microinverters and 25-year panels. We pull all LADWP permits, tie into the grid, and set up net metering so you watch the meter spin backwards. Typical payback in 5-7 years.

Energy Efficient Doors and Windows

We swap old single-pane windows for dual-pane low-E vinyl units with argon fill and foam-filled frames. Doors get multi-point locking Andersen or Milgard systems that cut thermal transfer by 30%. Every install is flashed, sealed, and city-inspected.
