Plumbing for Renovations & New Construction in Greater St John's
O.N.L Plumbing & Projects provides professional plumbing services for renovations and new construction projects in St. John’s area.
​
We work with homeowners, renovators, and builders to ensure plumbing systems are properly designed, installed, and code-compliant from start to finish.
General Home Renovations & Project-Based Work
In addition to plumbing services, O.N.L Plumbing & Projects takes on select general home renovation projects for homeowners in the Northeast Avalon.
For the right projects, we provide start-to-finish renovation support, including:
​
-
Bathroom renovations and upgrades
-
Flooring installation
-
Fixture and appliance installation
-
Plumbing and heating system integration
-
Coordinated renovation work for smaller residential projects
​
This approach is ideal for homeowners who prefer working with one reliable local contractor rather than managing multiple trades for smaller renovations.
​

All renovation work is completed with the same standards applied to our plumbing services:
​
-
Careful planning
-
Clean, professional workmanship
-
Clear communication
-
Respect for your home and timeline
​
By combining plumbing expertise with general renovation capabilities, we help streamline projects and reduce delays—especially for bathrooms, basements, and utility spaces.
