Builders and homeowners searching for a new construction plumber need a contractor who can hit framing schedules, pass inspections the first time, and document the system for warranty handoff. In Dallas–Fort Worth, that means coordinating with framers, HVAC, electricians, and inspectors while clay soils and fast build cycles leave little room for rework.
CMH Plumbing Solutions provides new construction plumbing from our Richardson office at 888 S. Greenville Ave, Suite #202, Richardson, TX 75081. Call (469) 972-6679 to discuss rough-in timing or a walkthrough.

What a New Construction Plumber Does
A new construction plumber installs the water supply, drain-waste-vent (DWV), and often gas piping for a home or commercial build that is not yet occupied. The job is scheduling-driven: miss a rough-in window and the whole project slips. Miss an inspection and drywall waits.
This is different from remodel plumbing, where walls are open selectively and fixtures already exist. New construction work follows plan sets, fixture schedules, and city or county inspection stages. Change orders happen—move a sink, add a bath—but they must be captured before insulation and drywall.
See our service overview for new construction plumbing and related commercial plumbing when the project is multi-unit or light commercial. Share CAD or PDF plans early so material takeoffs and lead times are realistic.
Rough-In, Top-Out, and Trim
Underground / groundwork places sewer and water services before or during slab work, depending on the foundation design. Mistakes here are the most expensive to fix later because concrete and grade are already committed.
Rough-in installs supply and DWV in walls and ceilings after framing. Nail plates, proper slopes, support spacing, and cleanout placement matter for inspection and long-term serviceability. Poor slope on a drain is a callback waiting for occupancy.
Top-out / stack-out completes vertical runs and roof penetrations so the system can be tested before insulation.
Trim sets fixtures, valves, and trim kits after finishes. A new construction plumber who disappears after rough-in leaves the builder scrambling at certificate-of-occupancy time—confirm trim responsibility in the contract. Include who supplies fixtures versus who installs them so there is no finger-pointing on delivery day.
Codes, Inspections, and Coordination
DFW cities adopt plumbing codes with local amendments. Your plumber should know the jurisdiction—Richardson, Dallas, Plano, and surrounding cities are not identical in every detail. Inspections typically include underground, rough, and final stages. Failed inspections usually mean slope, support, protection plate, or testing issues.
Coordination checklist for builders:
- Share latest plan revisions before rough-in—not after copper or PEX is hung
- Confirm water heater type and location (tank, tankless, recirculation)
- Align HVAC condensate and plumbing drains so conflicts are solved in framing
- Schedule pressure tests with enough time before insulation
- Confirm who pulls permits and who meets the inspector on site
For inspection-related testing after construction or during real estate transactions, CMH also provides hydrostatic testing when required by inspectors or foundation partners. Keep inspection tickets and photos in the job folder alongside the signed plumbing contract.
How to Choose a New Construction Plumber
- Licensed and insured for the project type
- References from builders on similar square footage and finish level
- Clear communication on lead times and change-order pricing
- Willingness to attend framing walkthroughs
- Documented testing and punch-list process
- Photo documentation of rough-in for future service
Price-only bids that ignore fixture count, material grade, and inspection rework risk are not savings. Ask what materials are specified and what happens if a plan changes mid-rough. A short interview about past failed inspections will tell you more than a polished brochure.
DFW New Construction Challenges
Expansive clay soils affect underground plumbing and future slab performance. Proper bedding, material choice, and coordination with the foundation contractor reduce callbacks. Summer heat affects crew productivity and material handling; winter freezes require attention to hose bibs and unfinished spaces before occupancy.
Labor and material lead times fluctuate. A reliable new construction plumber will tell you early if valves, specialty fixtures, or tankless units are delayed—so you can adjust the schedule instead of discovering it on trim day.
Custom homes and speculative builds both benefit from labeled manifolds and cleanout maps. Future service plumbers and homeowners need to know where shutoffs live behind finished walls. Spec builders should standardize layouts when possible so crews work faster and inspectors see consistent quality.
Materials and Fixture Planning
Decide early on supply material (PEX vs copper vs hybrid), water heater type, whole-home filtration or softener loops, and whether recirculation is required for large homes. Tankless units need correct gas sizing and venting coordination. Luxury fixture schedules change often—freeze the model numbers before trim orders go in.
Builders should also plan hose bib count, refrigerator water lines, ice makers, and outdoor kitchens in the rough—not as afterthoughts drilled through finished walls. Those “small adds” create the callbacks that wipe out thin plumbing margins. If the homebuyer selection meeting happens late, pad the schedule or hold a contingency allowance for plumbing changes.
Builder and Homeowner Checklist
- Confirm permit holder and inspection contacts
- Freeze the plumbing plan before rough-in day
- Walk the framed house with the plumber and superintendent
- Attend or review rough inspection results
- Verify trim fixture list matches what was ordered
- Collect as-builts and photos before closing walls mentally “done”
- Test every fixture at final before final payment
Homeowners buying new construction should ask the builder who the plumbing sub was and keep warranty contacts. If issues appear after move-in—low pressure, sewer smells, or leaks—call a local plumber quickly rather than waiting for punch-list season to end. Early photos help prove whether a defect is workmanship or misuse.
Warranty Handoff and As-Builts
At substantial completion, request: fixture model list, valve locations, water heater manuals, pressure-test notes, and a simple map of cleanouts. Store them with the home packet. When a future remodel needs a wall opened, that documentation saves days. For multi-unit projects, keep a unit-by-unit punch list so one suite’s issues do not block CO for the whole building.
CMH Plumbing Solutions can support builders who want a clear handoff package as part of the new construction scope. Call (469) 972-6679 during preconstruction, not the week of drywall.
FAQ: New Construction Plumber
When should a new construction plumber be hired?
Before groundwork when possible, and no later than framing, so underground and rough-in are planned together.
Do you work with custom home builders and production builders?
Discuss scope and schedule by calling (469) 972-6679. Provide plans, address, and target rough-in dates.
Can you handle commercial new construction plumbing?
Light commercial and multi-unit work is discussed case by case. Start with our commercial plumbing page and a plan review.
What if plans change after rough-in?
Expect a change order. Moving drains after drywall is far more expensive than moving them in framing—decide early.
