Our Core Remolding or New Construction Services
New commercial plumbing and tenant improvements involve installing heavy-duty pipes and systems for businesses. Remodels require rerouting main water lines, adding gas hookups, and updating restrooms to comply with legal requirements.
Commercial remodeling requires specific steps to ensure everything works properly and complies with the law.
- Tenant Improvements: Customizing commercial spaces for new businesses or apartments.
- New Construction: Installing new piping, backflow prevention, and water heaters from the ground up.
- ADA Upgrades: Modifying restrooms to comply with the Americans with Disabilities Act (ADA) guidelines (e.g., grab bars, sink clearances, and automatic-flush valves).
- Commercial Retrofits: Upgrading old pipes to meet modern safety and water conservation standards
Most Common Commercial Plumbing Services for New Buildings
Water Pipes
The first important component of new construction plumbing is installing water supply pipelines. These are pipelines specifically built to bring in fresh potable water from an external water source.
Drain Pipes
Drain pipes are another essential component in almost all plumbing construction projects. These pipelines, which are often much larger than water supply pipes, transport wastewater to an external location.
These pipes connect to common amenities such as sinks, showers, and toilets before exiting the facility to the city sewer system or a private septic system.
Water Heater Installations
Another common component in new construction plumbing is a water heater system installation. New-construction plumbers install them and connect them to the water supply piping so that hot water is available at fixtures such as sinks and showers.
Water heaters are frequently installed in a pan connected to a drain. This method is done so that if the water heater leaks, the resulting water will be captured in the pan and carried away through the drain pipe.
Fixture Installations
Plumbing fixtures are often the last components installed in new construction plumbing. At this moment, we install sinks, toilets, faucets, bathtubs, and showers in a bathroom.
This work is typically done in the last stages of a building’s construction, and is considered the finishing touch to any new construction plumbing project
Common Commercial Plumbing Services & Repairs
Commercial plumbing serves large buildings such as restaurants, offices, and schools. Common services include drain cleaning, sewer repair, and water heater installation. Plumbers also fix leaks, install gas lines, and test backflow systems. These tasks keep businesses safe and open.
Drain Cleaning and Hydro-Jetting: Businesses experience heavy clogs in pipes from grease and waste. Plumbers use hydro-jetting, which blasts high-pressure water to clean pipe walls.
Grease Trap Maintenance: Restaurants must trap oil before it enters city pipes. Plumbers clean and pump these traps to stop nasty smells and huge fines.
Backflow Testing: Backflow devices prevent dirty water from entering clean drinking water. Cities require annual testing to ensure these valves work properly.
Commercial Water Heaters: Offices and hotels use massive amounts of hot water. Plumbers repair and replace large commercial boilers and tankless water heaters to keep guests happy.
Sewer Camera Inspections: Instead of digging up parking lots, plumbers send video cameras into pipes to find exact break points.
ADA Restroom Upgrades: Public buildings must comply with the Americans with Disabilities Act (ADA) rules. Plumbers install touchless sinks, low-flow toilets, and grab bars to comply with these laws.
A well-maintained plumbing system is vital for keeping your business operations smooth and avoiding costly disruptions. Many plumbing emergencies can be prevented with consistent care, proactive inspections, and the right professional support.
Key Commercial Maintenance Tasks
Commercial plumbing needs regular care to prevent costly business shutdowns. Routine leak checks and fixing running toilets are also important to save water and money.
Drain and Sewer Cleaning
High-traffic facilities get clogged fast. Routine drain cleaning removes soap scum, hair, and scale. For severe blockages, plumbers use hydro jetting, which uses high-pressure water to blast away buildup.
Grease Trap Maintenance
Restaurants and commercial kitchens require frequent grease trap cleaning. Traps catch Fats, Oils, and Grease (FOG). If you do not pump them out every 1-3 months, they cause foul odors and pipe backups.
Backflow Prevention Testing
Backflow happens when dirty water flows backward into the clean water supply. Commercial buildings must have their backflow devices tested annually to comply with health and safety codes.
Water Heater and Boiler Service
Commercial water heaters work hard. Maintenance includes flushing out sediment every 6 to 12 months. Sediment acts like an insulating blanket, causing the heater to run longer and use more energy. Plumbers also test the Temperature and Pressure (TPR) relief valve to prevent the tank from exploding under extreme pressure.

Proactive Leak Detection
Monitor Water Usage: Check your monthly water bills for unusual spikes. A hidden leak wastes thousands of gallons.
Test Water Pressure: High water pressure (over 60 psi) puts excess stress on joints and pipes. Use a simple pressure gauge to ensure your building’s water pressure stays in the safe range of 40 to 60 psi.
Check Fixtures Regularly: Inspect sinks, toilets, and urinals daily. A running toilet or a dripping faucet wastes hundreds of gallons per week. Replace worn washers and flappers quickly to avoid large utility bills
