Plumbing Systems Installed Right From The Start

DNI Heating and Air handles plumbing installation for new residential and commercial construction projects in Boulder.

When you are building a home, apartment complex, or commercial space in Boulder, the plumbing system needs to be installed correctly before walls close up and floors get poured. You need licensed plumbers who understand how drainage, water supply, venting, and fixture placement work together in new construction, whether the project is a single-family home in Boulder or a multi-story office building.


DNI Heating and Air installs plumbing systems for new construction projects including homes, apartment buildings, restaurants, office spaces, retail buildings, schools, gyms, and hospitals. The work covers drains, sewer lines, water supply lines, appliance hookups, water heaters, and all rough-in and finish plumbing required to bring the building online. DNI Heating and Air is fully licensed and insured.

Rough-in, inspection, and finish work coordinated with your build

The plumbing installation in Boulder begins with reviewing the building plans, then running supply and drain lines through the framing before drywall goes up. The rough-in phase includes placing pipes for sinks, toilets, showers, dishwashers, water heaters, and any other fixtures or appliances that require water or drainage.


Once the rough-in passes inspection and walls are finished, the plumber returns to install fixtures, connect appliances, test water pressure, check for leaks, and verify that drains flow correctly. You will turn on faucets that deliver steady pressure, flush toilets that clear completely, and run showers that drain without backup or pooling.


The installation meets local building codes and coordinates with the general contractor's schedule to avoid delays. The service does not include site excavation or foundation work, but it does cover everything from the main sewer connection to the final fixture installation, including any specialized plumbing for commercial kitchens, medical facilities, or multi-unit buildings.

Most contractors want clarity before breaking ground

Builders and property owners usually ask about coordination with other trades, how inspections are handled, and what happens if plans change mid-project.

What does rough-in plumbing actually involve?

DNI Heating and Air services breweries, restaurants, and coffee shops throughout Boulder. The work covers any commercial kitchen or food prep space that relies on refrigeration, ice production, or cooking equipment.

How do you coordinate with the general contractor?

DNI Heating and Air schedules rough-in and finish work around framing, drywall, and inspection timelines provided by the general contractor. Communication happens throughout the project to keep plumbing on track with the overall build.

What types of buildings do you install plumbing for?

DNI Heating and Air works on residential homes, apartment buildings, restaurants, office spaces, retail buildings, schools, gyms, and hospitals in Boulder. Each type of building requires different fixture counts, drain sizing, and code compliance.

What happens if the building design changes after rough-in starts?

If fixture locations or layout changes occur, the plumber adjusts pipe placement and stub-out positions as needed. Changes may affect the timeline and cost depending on how much work has already been completed.

How long does plumbing installation take on a typical project?

Timeline depends on building size, fixture count, and how the work fits into the construction schedule. A single-family home in Boulder might take a few days for rough-in and another day for finish work, while larger commercial projects take longer.
