New Construction Plumbing in Hamilton, NJ
Building on an existing lot calls for a different plumbing review than starting on an open site. For Hamilton new homes, replacement homes and major additions, we start by looking at what is staying, what is being removed and where the proposed utilities will enter the building. Existing water and sewer connections should not be assumed to suit a new floor plan without a review. The same applies to the capacity and condition of piping that an addition will depend on. We work from architectural plans and the fixture schedule to lay out the underground, drain and supply work, then coordinate the rough-in with the framing and other trades. Tell us whether the site uses public water and sewer or a private system, and include a site plan if one is available. From the first underground connections through the final fixtures, the aim is a clear scope that fits both the new construction and the existing conditions.

A few practical questions
Before we get started
Do you bid plumbing for Hamilton additions?+
Yes. Include drawings of the addition and the existing plumbing connections it will use.
Can existing utility connections be reused?+
That depends on the proposed demand and site conditions. Existing connections need to be reviewed as part of the scope.
Should demolition details be in the bid package?+
Yes. Mark what stays and what is removed so the plumbing work can be scoped accurately.
