Phoenix Home Addition Top-Out Plumbing Done Right

Top-out plumbing is one of those phases that most homeowners never think about - until something goes wrong later. It's the stage where all the supply and drain lines get run through the framing before the walls close up. Get it right here, and the rest of the build goes smooth. Cut corners, and you're dealing with costly fixes after drywall is already up.

On this Phoenix addition, we just wrapped the top-out. Red and blue PEX supply lines are run clean through the framing, drain lines are set, and the pressure test gauge is in place to confirm everything holds before we move on. That pressure gauge isn't just a formality - it's how we know there are zero leaks hiding inside the walls before they get covered up.

This is the kind of work that separates a well-built addition from one that causes headaches down the road. When supply lines are routed properly and drain rough-ins are set at the right locations and heights, every fixture that gets installed later just drops right into place. No re-routing, no surprises, no callbacks.

Additions are one of our core services, and this is exactly why we take the rough-in phases seriously. The finish work gets the attention, but the bones of the build - the framing, the plumbing, the mechanicals - those are what determine how the finished space actually performs for years to come. A solid top-out is just part of how we do things.

If you're thinking about adding on to your Phoenix home or starting a remodel, this is the kind of team you want behind it - one that sweats the details you'll never see once the walls are closed.
