New Construction Plumbing

Built Right From the Start

Plumbing That Lasts Decades

New construction plumbing sets the foundation for how a home or building will function for decades. Get it right at this stage and you avoid years of avoidable repairs, callbacks, and code issues.

As a new construction plumbing company based in Catonsville and serving Baltimore County and Howard County, we work with builders, contractors, and homeowners to design water and drain layouts, install complete plumbing systems before walls go up, and coordinate with the project schedule.

That includes permit handling, code compliance, fixture placement planning, and proper venting. Plus on-time delivery so we don’t hold up the build, and clear upfront estimates so plumbing for new construction stays on budget.

  • Underground, in-wall, and in-ceiling plumbing
  • Water supply and drain/vent systems
  • Fixture connections and shutoffs
  • Sump pump piping
  • Permit acquisition and inspection coordination
  • Custom layout design

How New Construction Plumbing Works

New-build plumbing happens in three coordinated phases, all permitted and inspected by Maryland counties. We work with your GC, architect, and inspector from rough-in through final.

Underground Rough

Drain, waste, and vent lines installed before the slab is poured. One shot to get this right. We plan it carefully.

Above-Slab Rough

Supply lines and DWV branches run inside walls before drywall. County inspection is required before close-up.

Trim & Final

Fixtures installed, valves connected, system pressure-tested, water heater set, and final county inspection passed.

Frequently Asked Questions

Do you handle new construction plumbing?

Yes. From underground rough-in through final fixture set, for new homes, additions, and tenant build-outs.

Residential and commercial projects?

Both. See our commercial plumbing services for retail, restaurant, and multi-unit work.

Do you handle permits and inspections?

Yes. We pull the required permits and coordinate inspections so your project stays on schedule and to code.

Can you work from our architect’s plans?

Absolutely. We plumb from your plans and flag any issues early, before they’re built in.

When should a plumber get involved in a build?

As early as possible. Involving us during design and rough-in avoids costly changes later. Call (410) 242-3111.

What areas do you serve for new construction?

We are based in Catonsville and handle new construction plumbing throughout Baltimore County and Howard County, so builders and homeowners nearby can line up a reliable crew for the whole build.
