Guest House, ADU and Addition Plumbing in Apex, NC
Guest houses and additions need plumbing that ties into the existing house without overloading old drain lines. We locate the existing sewer, check its condition with a camera and confirm there is enough fall to the new building. Supply lines can be branched from the main house or run as a separate service, depending on distance and pressure. We also handle the trenching between structures and restore the yard when we are done.

Commercial and Multifamily New Construction in Apex
We also plumb small commercial buildouts, offices, retail suites and multifamily projects. These jobs often require grease interceptors, backflow assemblies, commercial water heaters and ADA compliant fixtures. We read commercial plans, coordinate submittals and keep the general contractor informed through each inspection. Our crews scale up so plumbing never becomes the bottleneck on your schedule.
Gas Piping for New Homes in Apex
We size and install gas piping for ranges, water heaters, furnaces, fireplaces, pool heaters and outdoor kitchens.

The system is pressure tested and inspected before the utility sets the meter.
