If your room addition project includes a new bathrooms, kitchen, or laundry, we can do the rough and/or finish work required to complete the job per your choice. Each project is different, hence, we’ll provide you with a custom bid per your desire. In case you are looking for a 100% complete plumbing job, we would still need you to select and pay for the fixtures (tub, toilet, sinks, faucets, etc.). We will provide you with a custom-list of fixtures for your project, including specs on building code requirements, best places to shop, and when you’ll need to make your selections by. All and any plumbing work cost is ADDITIONAL to the basic package cost.


Our “Single Story Room Addition” package includes all the receptacles required by CEC (California Electrical Code) such as: indoor & outdoor outlet, outdoor light installation (fixture provided by the homeowner), light switches, dimmers, and hard-wired smoke detectors (in the new addition ONLY!). Other electrical fixtures, such as: recessed lights, LED lights, ceiling-fans, bath exhaust-fans, etc, or other fixtures required by the building inspector for the existing home area, can be installed per request/design for ADDITIONAL charge.
