Gas Line Installation in Trenton & Quinte West

Whether you are adding a gas range, connecting a BBQ on the deck, running a line to a new fireplace, or roughing in gas for a new home in Quinte West, the work must be done by a licensed gas technician and pressure-tested before any appliance is connected. Brandon handles the full scope — from sizing the line to the final pressure test and connection.

Gas line sizing is not guesswork. The line must be sized to deliver adequate pressure and flow to every appliance connected to it, accounting for the total BTU demand and the length of the run. An undersized gas line causes appliances to underperform, leads to pressure drops during peak demand, and can cause nuisance shutdowns on high-efficiency equipment like Navien tankless water heaters and condensing furnaces.

For new construction in Trenton, Quinte West, and Brighton, Johnston Mechanical handles the full gas rough-in — meter connection, main trunk, and branch lines to each appliance location. Brandon coordinates with the builder to ensure the rough-in is completed at the right stage and that all lines are properly supported, protected, and accessible for future service.

For existing homes, Brandon can extend your current gas system to reach a new appliance location, add a dedicated line for a BBQ or outdoor kitchen, or run a line to a garage or workshop. He assesses your existing meter capacity and main line size before any work begins to confirm the system can handle the additional load.

All gas line work by Johnston Mechanical is pressure-tested before any appliance is connected. Brandon uses a calibrated gauge to hold the line at test pressure and confirms there are no leaks before signing off on the installation. This is not optional — it is the standard that protects your family and your home.

Gas line work is one area where hiring an uncertified contractor creates serious liability. If a gas leak or fire occurs and the work was not done by a TSSA certified technician, your insurance may not cover the damage. Brandon is fully certified and carries the documentation to prove it.
